What do stock LS1's dyno/run in the 1/4?

[2000z28]

DarthD
its a dynojet model 248x

[IrS89IROC]

yeah.....and my 90 5.7 TPI is faster than her car......and its only 215 rwhp and 338 rwtq.
Hell yeah, i have 89 iroc L98. got rebuilt with stock parts, so it's a 355. All i have is a home made cold air running into the stock gutted box and a dynomax cat-back system and i beat brandnew manual 350zs all the time.

[tx77015ls1]

A stock IROCZ can do 14.5@95 all 350 IROCZ were automatic

They were rated from 220 HP fpor the early ones allthe way to 245 for the later models

I love the third gen f-bodies I has Two 84 Z28's

a LG4 305 Automatic T-Top

and a L69 H.O. 5 speed hard top

[DarthD]

If your car is an auto, then that is a little on the low side. If it is a six speed then it is very low. Are the numbers corrected to SAE? If not, that could explain it.

From what I have heard, a Flowmaster muffler will not give an LS1 any power increase and there have been mixed results for the programmers. (I assume this is what you mean by 'chip'.) I think some people have said they have lost power with a programmer.

[2000z28]

i dont know what u mean by corrected by sae, i am new to the whole drag racing scene, the programmer "chip" i have is made by superchips, i only bought it to recalibrate my speedo for my 3.42 gears, in some ways i like it, but a lot of times it seems like it is slower than before, does anyone else have the same programmer? i was pretty pleased with my 13.5, i thought it was pretty good considering it was my first time racing and i didnt deflate my tires at all, but apparently others are running the same times stock, so should i take the flowmaster off?

[Ramairgod]

I had mine Dynoed this past weekend...324rwhp and 334rwtq

[tx77015ls1]

RAMAIRGOD, did you ever run yours in the 1/4 or just the 1/8th?

I ran a 8.6@85 8th

http://www.cardomain.com/ride/2348722 my car

[Roastem]

I have a 02ss with slp options includes the blackwing box, cat back dual dual. The factory rated it at 345rwhp I wanted to add some stuff to it but before I did I had it dyno and it was 345rwhp. I could not believe it but that what it ran. Since then I added a mass air sensor BBK throttle body and got a Diablo turner and I can tell it is faster now but I haven't made another run on the dyno yet. I haven't taken it to the track yet so I don't know what it runs in the 1/4.

Factory rated at 345 rwhp? And you dynoed it and spat out 345 rwhp with just a lid and catback? Sounds a little fishy. Did you buy it used, maybe somebody slipped a cam in it or something?

[Toadman]

Mine was dynoed on a mustang dyno 2yrs ago. It was 279hp and 304 tq (all mods except headers and pulley). Then I did a 1/4 on it and ran a 13.7 @ 104mph. I was very dissappointed with it. I ran a GTP that ran 13.8 on the street before that and beat him by 3 to 4 cars 2 different times and the last time spun starting out but passed him at 70mph. Something does add up but I will get it redynoed on a dyno jet after I get a throttle body and pulley installed.

[tx77015ls1]

Do you have a K&N? I raised my air box as far as I could. I also cut the bottom out 0of my air box to expose as much of the filter area as posible.

I think that helped alot.

how many miles?

[Toadman]

I had probaley like 17000 miles on it when i did the dyno. I have a K&N filter but the box isnt raised. I did think about it after I dynoed it that day and my hood was partly latched and I think the rubber seal that came with the hood blocked alot of the air coming from underneath the car.

[BobsSS]

Factory rated at 345 rwhp? And you dynoed it and spat out 345 rwhp with just a lid and catback? Sounds a little fishy. Did you buy it used, maybe somebody slipped a cam in it or something?



The factory rating is 345 flywheel hp. I don't know about his dyno #'s. I have the 345 option but have never had it on the dyno.

[onehotcavalier]

Glad I live in Houston!!!... If I only Ran 14's I wouldn't bother going. I ran low 13's at 106 in the 01 cobra. Haven't had a chance to run the vette yet. But I would see LS1s running high 12's low 13's all day at baytown. Saw a friends ls1 z28 Dyno at 305 rwhp stock

[Cobra2WS6]

Never had it dynoed but ran 13.4@107 stock. SO I am guessing it had over 300rwhp

[CockerKid009]

lookin @ the dyno sheet on the second page made me wonder about a torque converter.. i have a stock 99 A4 w/ 20K miles. I think im gunna put a B&M Transpak w/ tranny cooler and then prob. a converter... should i run a 3600 or is that too high, keep in mind it's bone stock. Should i spend my money on a comp cam and K&N Cold Air first or not?

[tonyjnjz]

motertrend/car n driver.....a true testiment to what a car is capable of can be found there.........fbodys have always run 13.1 to 13.5 or so in ...at 103-108mph with 6 speeds usually being the higher of the 2. i remember an article back in 98 or 99 where they tested a ws6 6 speed at 13.09 at 107.8...bone stock obviously

[WishIHadAPantera]

While magazines are great, we all know that they have little significance when a real owner brings them to a real track...

[joe98redss]

My brother just ran his 00 trans am at super chevy (maple grove raceway). His only mods are magnaflow catback and the free mods. His best time of the weekend was 13.4 his avg. was about 13.5 his first time running the car.

[J'stransam]

At our local track where traction is a problem for every car it seems, Iv never seen a LS1(most are stock or close that Iv seen) not in the 13s usally in the 13.4-13.6 range. My car ran a 13.5 last time I ran it with 2.1 60ft.

[slpfirehawk00]

2000 6spd firehawk dynoed 320 rwhp 335 tq on mustang dyno and ran a best of 12.9 @ 109 and a couple 110's but slower times in the 1/4 mile. This was in michigan.

[GA Country Boy]

I'm not sure if I understand this thread, but a car weighing 3,400 lbs and putting down 255 HP should run around 13.81@97mph regardless of which motor. It's a weight/HP thing. I chose 255 figuring a 15% loss off a 300HP motor.

[tonyjnjz]

im not sure u understand stock ls1 camaro/firebirds in general...even the car mags posted times in the low 13s at 105 to 107 stock obviously...gm rated them at 305 and its obviously underrated....hummm

[GA Country Boy]

The INITIAL post in this thread said:"So, all you who actually KNOW a thing or 2 about LS1's, what do they dyno and run in the 1/4 stock?"

The question was about LS1's NOT about camaros/firebirds or any specific car.
As far as I know, the term 'LS1' refers to an engine NOT a specific car. In fact I was not professing any specific car knowledge, but merely stating mathematical calculations which are easily verified by anybody who wishes and apply to all HP/Weight applications.

[tonyjnjz]

instead of using math to figure out rwhp using the manufactur's stats y dont u just go by a much more reliable source like a dyno???????

Yeah, but truthfully LS1 fbody isn't really a 300 bhp motor.:true: Vette LS1(engine)= Fbody LS1 (engine)

[GA Country Boy]

I'll leave that up to you. So just post your address where everybody can take their cars so you can dyno them for free. And you will need an engine dyno since this thread (like I pointed out previously) is about the LS1 engine. Also obviously you are not really familiar with dynos if you believe they are "a much more reliable source". Again my post was merely an example of what would be expected from a certain combination. If you believe the combination should be different insert your own numbers and punch out the results yourself. Do you really think manufacturers build engines NOT knowing what to expect from them BEFORE they build them?

As to the above post: "Yeah, but truthfully LS1 fbody isn't really a 300 bhp motor. Vette LS1(engine)= Fbody LS1 (engine)"
See my previous post. This thread is NOT about F or Y body cars, but is about the LS1 engine. BUT since you made the statement "Vette LS1(engine)= Fbody LS1 (engine)", WHICH years of engines are you comparing? Or are you saying ALL vette LS1 engines are the same as ALL F body LS1 engines?

[1320 King]

I got my SS with 48,000 on it and it dynoed stock at 310rwhp

[skar]

I got my SS with 48,000 on it and it dynoed stock at 310rwhp

? On a Mustang or dyno jet dyno.

[GA Country Boy]

I got my SS with 48,000 on it and it dynoed stock at 310rwhp

AND HOW do you know if it's 'stock' when one or more people had it for a couple years BEFORE you? I am sure whoever wound up with my last car probably thinks it's 'stock' too, but it's not. The heads LOOK 'stock', but they are not. Nobody can SEE the higher compression ratio or the different rear end or cats (unless they get underneath and look) or the expert non 'stock' tune. It's also pretty tough to tell the difference between an LS1 and an LS6 intake unless you have them off the car.

And as SKAR was subtly hinting at, different dynos can and often do produce different results. That's why I specify in my sig the make AND model of the dyno that produced the results I am showing. Just to double check I run on a different dyno from time to time just to make sure the results are in the same ball park.

[slpfirehawk00]

Agreed to GA BOY. Except people who know the cars should be able to tell a ls6 intake from a ls1, but then again prolly not.:yup:

[Bob'sWS6]

Agreed to GA BOY. Except people who know the cars should be able to tell a ls6 intake from a ls1, but then again prolly not.:yup:

I can't tell an LS6 intake from an LS1 intake without looking at the bottom of the intake. They look identical up top. Short of the egr delete is the only way I can think of telling.

[tonyjnjz]

ppl dont know if there car is stock GA boy??? ive heard of MANY ls1's ( camaro, trans-am, vettes) 1 owner cars that dyno near or above 300 rwhp ...man your right, gm is right on with that 305 flywheel hp.....u also claim an ls1 in a 3400 lb car should run 13.8 at 97 ..funny ive never heard of anyone trapping that low near sealevel in a stock ls1 ...except maybe that heavey ssr thing.lol

So you have heard of "MANY ls1's" that "dyno near or above 300rwhp", BUT "have NEVER heard of ANYONE trapping that low". I think you nust have a great imagination or very selective hearing. OR your MANY ls1's are ALL the 350hp version
which will dyno around 300rwhp (350 X .85 = 297.50). As I posted previously
"I chose 255 figuring a 15% loss off a 300HP motor." (300 X .85 = 255) OBVIOUSLY if you want to choose a 350 horse motor the numbers will be different.
Run your numbers yourself: www.rpmoutlet.com/dyno.htm

BTW, tonyjnjz I was wondering if the numbers you are quoting are from your "reliable source" dyno? Or are you making them up to suit yourself? Or do you really believe a stock 300 horse motor is still going to be putting out 300 or more horse power at the rear wheels?

[preppy]

I'm having a gay little argument with someone jackass on another board who know's absolutely NOTHING about cars, yet he sits in front of his comp and insists that LS1's dyno under 260rwhp stock and run low-mid 14's.

I'm going to link this thread to that other board. So, all you who actually KNOW a thing or 2 about LS1's, what do they dyno and run in the 1/4 stock?

I think you are referring to a Dynojet model 178. Model 178 is specifically for Legend Cars and vehicles of the same size and power output and is limited to
a maximum of 500 HP. "Eddy Current" is the retarder option. I have no personal
experience with that model since I've never raced Legend cars so I can't vouch for its accuracy or lack of, but generally Dynojets are pretty reliable. I am more
familiar with the dynos in the Atlanta area like the model 248-C I usually use which is good to 2,000 HP, but I still make occasional runs on other dynos to make sure the numbers are in the same ball park.

[preppy]

Aaron Scott of SGC is pmimarily into vipers now, he has a twin turbo built viper dynoed on his machine at 1267hp - so its at least good for that. I went to U.S.19 dragway today an ran consistant 8.80-8.90 at 83 mph

Then it must not be a model 178. I was just going by your description.

YOU are the one who said "motertrend/car n driver.....a true testiment to what a car is capable of can be found there....", so I went to see what the "true testiment'' was, and lo and behold it aint what YOU said! BUT now you don't like
their "true testiment". It's there in black and white for everybody to see, but now instead of showing proof of what you said about Motortrend/Car 'n Driver you give us a link to somebody's personal website on AOL who SAYS it's from Popular Mechanics. AND YOU copied it as if it was from Popular Mechanics which it isn't. It's from some unknown person's web site. Which really has nothing to do with Motortrend/Car 'n Driver anyway.

As to your ignorant post: "thats also a vert ga boy?? r u kidding me...we all know there heavier and because of that slower ..your a tool"
If you don't like the link I gave to Motortrend/Car 'n Driver then give us a link to them that backs up what you said. YOU'RE the one who said the "true testiment" could be found there. I didn't pick what they did or didn't test.
Don't forget YOU are the one who said "a true testiment to what a car is capable of can be found there....", so being childish and calling me names is not going to change the facts. Obviousy you were either innocently mistaken or just plain lieing, either way I really don't care, but your response seems to

If you find it fine. If you don't it doesn't really matter. BUT you should tell us about YOUR car. I think that would be a much more interesting subject than 300 rwhp cars! Lingenfelter puts together pretty impressive machines and yours is probably one of them. A Lingenfelter 383 is something worth talking about.

[tonyjnjz]

what would u like to know? numbers are 395 rwhp and 399 rwtq when it had no miles on it as the 383 package was installed when the car was brand new....picked it up used a few mths ago for 19,500 with 17k miles on it...its pewter, 6 speed, the man i bought it from is 61 yrs old..car was babied..its immaculate and im lovin it so far....traction has been a prob as the weathers getting a lil cooler..really need some drag rads out back. Car also has the stock suspension so far with the exception of a bmr tq arm i put in a few weeks ago.....has stock exaust manifolds and its REALLY in need of headers..prolly wont be able to pulll that off till spring though...i used to own a 99z 6 speed that was pretty much stock with a few bolt ons then the last 3 yrs i had an rsx-s before buying this car so im learning all over again. Your monster vette sounds even more sick though

[GA Country Boy]

That 383 Lingenfelter package I think was around 465 HP (so less 15% puts it
just shy of 400rwhp), but I am surprised they didn't feel it was necessary to put headers on it, because they would have done everything else including heads and cam. Maybe they tried to keep it a little quieter, more stealthy, 'cause the headers always makes them noisier. You got a really good deal 'cause the 383 package is worth around $15,000 by itself! And of course when Lingenfelter builds it you know you have got reliability/streetability not like mine. To be able to drive mine (on the street) in the warm weather, I had to put a larger trans pan on adding three quarts of fluid AND an extra trans fluid cooler with a thermostatically operated fan on it AND a larger Be-Cool radiator or it will overheat.
In any event it would be interesting to see what a set of long tube headers would do for you and since your engine is already forged you could always add a blower if you want to get 6-700rwhp or you could just add a little nitrous! 8-) OR you could just leave it like it is...400rwhp is nothing to sneeze at and it will blow away most cars on the road. BTW with 17k on it it's just nicely 'broken in'. You really did get a great deal!!!Have you taken it to the strip? 'Cause I would imagine you would see around 11:77@115.8.

[tonyjnjz]

nope no strip yet...definitly in the future im sure though...yeah im thinking the same thing about headers 30 rwhp maybe? i know stock ls1's usualy see about 20...as far as the 465 number my paperwork rates it at 460.....the package being installed back in 01 maybe it was slightly diff back then? i figure at 15 percent only about 450-455 though....i also figure the car had 0 miles on it when it was installed and dynoed..yes i think i got a great deal as well...thank you....its the only reason i actualy have the car..i wasnt looking for a car and took what i thought was a cheap stab at it on ebay...and to my shock the reserve is met and the gf is pissed..LOL...as far as upgrading the car i think im gonna stick to just the headers, then suspension for now and maybe brakes in the future....the car really is more than fast enough for me...i cant imagine 6-700 rwhp on the streeet....i barely use all the power the car has now with the exception of highway onramps and when im racing somone.....11.77 that would be one hell of a run....ill be more than happy if i can touch 11's !!

[tonyjnjz]

oh and this is what lpe said about y they didnt install headers on it

Hi Tony,

We looked into some long tubes for the F-bodys, but legally we weren't
allowed to modify the emission systems on new vehicles
(cats). Thus that is why we did not install LT headers on these
vehicles. I would consider the Kooks long tube headers and Y pipe
with cats for your combination. Price of the headers, cats and Y would
be $1395.00. I would then take it to someone for a tune, to
make sure everything stays safe. Just let me know if you would like a
set!

Damn ErikElvis you're a nice guy, but despite all my drag racing and other racing experience you're losing me. I don't know if it's a "generation" thing, but I don't have a clue what you're talking about!!! SFC's, STB, DD, ??? I think the LM2 is a wide band sensor, but...is this a "trekky" thing? :brick:
BUT congrats on your time. It's a good start!

[smg267]

I got mine dynoed with slp headers and ory / lid and put down 334 h.p. and 368 t.q. at 90 degrees and 40% humitdy. All through the stock Z/28 catback!:nana: I am hoping for 340+ with a new catback.

Ha! SFC's = Sub frame connectors, STB = Strut tower brace, LM2 = SLP loud mouth 2 cat back. DD = Dual dual SLP exhaust. Could get the quiet version which I had or the loud mouth versions. Its the 2 pipe on each side set-up.

stock i went 13.177 @ 110.24 m6

[S8ER01Z]

I'm not sure if I understand this thread, but a car weighing 3,400 lbs and putting down 255 HP should run around 13.81@97mph regardless of which motor. It's a weight/HP thing. I chose 255 figuring a 15% loss off a 300HP motor.

Its funny... my 1995 LT1 Automatic Z28 with 3.23s ran 14.1 @ 97mph on a 2.160ft. (76K on the clock and my trans required a rebuild a week later)...

That seems to back the entire LT1 being rated on the low side. ;)
Since the LT1 was a 300hp motor... think about it.

My 2001 M6 Z28 just ran 13.4 @ 104mph on a 2.1 60ft in 3200DA.

I am guessing I have a little bit more than 305~310hp at the crank. :nana:

I ESTIMATED the ET's based on the horsepower and weight indicated. IF YOUR LT1 weighed the same my estimate was exact at the same MPH and optimistic on the ET by three tenths. The same car can vary by three tenths with different drivers and also weather/track conditions. Mathematical calculations of ET's are not intended to be an exact science since there are so many variables involved, but used more as a general guide. IF ALL similar cars ran the same ET's there wouldn't be the amazing NHRA records set in the legal stock classes. For example, a '98 Camaro holds the C/FIA record of 10:68@124.20; an '02 Firebird holds the A/FIA record of 9:91@132.43.
IF you want to know EXACTLY what your rear wheel horsepower is put it on the dyno, and then if you want to know what your flywheel horsepower is you can ESTIMATE it or pull your engine and put it on an engine dyno.Here is a link with a lot of good calculators, run your own numbers. www.wallaceracing.com/Calculators.htm

I can see what you are saying... My LT1 actually tipped the scale at 3546lbs with me and a half tank of gas.

It's pure fact that the 305/310hp rating from GM was bogus on the LS1. Some 8+ years later its still lost of people...

[Wesman]

you are giving the car WAYY too much credit. There are plenty of 14 second F-bodies and cars that do not dyno above 300.

Umm no...any LS1 running 14's has something wrong with it. Plain and simple.

[GA Country Boy]

Umm no...any LS1 running 14's has something wrong with it. Plain and simple.

I don't know if I would put it exactly like that, but I think 13's should be easily
achievable without any major mods.

13's are achievable bone stock.

I think I have more somewhere. I know I am missing the Camaro from Muscle Mustang that ran a 12.8X. I also know I have more Autos somewhere.

I also have plenty of data from LT1 back and Mustangs, Corvettes, GTOs, and more. If someone wants to see anything else, let me know and I'll post what I have.

I have been saving this stuff for years.

[DarthD]

Here is some Dyno information...
(I have been collection dyno sheets from stock cars for a while. I have averaged the numbers for each car to get the follwing)

2002 Camaro SS T56 - 314 avg rwhp Rated FWHP 325-345
2001 Camaro SS T56 - 314 avg rwhp Rated FWHP 325
2000 Camaro SS T56 - 311 avg rwhp Rated FWHP 320
(none SS cars averge about 7 hp less so far, but I do not have a very large sample size for them yet.)

2002 Firebird WS6 T56 - 314 avg rwhp Rated FWHP 325
2001 Firebird WS6 T56 - 315 avg rwhp Rated FWHP 325
2000 Firebird WS6 T56 - 311 avg rwhp Rated FWHP 320
2002 Firehawk T56 - 317 avg rwhp Rated FWHP 325 - 345

It is interesting to note that I have seen no difference between the 2002 cars with and without the SLP 345 hp lid/muffler package.

2006 Corvette Z06 T56 - 443 avg rwhp Rated FWHP 505
2005 Corvette T56 - 351 avg rwhp Rated FWHP 400
02-04 Z06 Corvette T56 - 353 avg rwhp Rated FWHP 405
2001 Z06 Corvette T56 - 342 avg rwhp Rated FWHP 385
1996 Grand Sport Corvette - 298 avg rwhp Rated FWHP 330

2005 GTO T56 - 350 avg rwhp Rated FWHP 400

2005 Mustang GT T5 - 265 avg rwhp Rated FWHP 300
99-04 Mustang GT T5 - 230 avg rwhp Rated FWHP 260
2001 Mustang Bullit T5 - 235 avg rwhp Rated FWHP 265
2003 Mach I T5 - 275 avg rwhp Rated FWHP 305
2004 Mach I T5 - 275 avg rwhp Rated FWHP 310
2001 Cobra T5 - 275 avg rwhp Rated FWHP 320
96-98 Cobra T5 - 261 avg rwhp Rated FWHP 305
03-04 Cobra T56 - 366 avg rwhp Rated FWHP 390

This data is taken from hundreds of bone stock dyno tests performed on different dynos across the country.

I have more cars, but the sample size is still small for them.

You can take the rated FWHP and subtract drivtrain loss to see which cars are underrated. Drivetrain loss for a manual seems to be around 12% when comparing numbers using GM's correction factor to the aftermarket correction factor.

The LS1 Camaro's and Firebirds are WAY underrated.
The 03-04 Cobra is underrated.
The 2003 Mach I is a little underrated.
The rest are pretty much right on.

[GA Country Boy]

Did I say something you didn't like?

I said: "I think 13's should be easily
achievable without any major mods."
You said: "13's are achievable bone stock."

Is there a BIG difference between "no major mods" and "bone stock"?
I'm not sure if anybody has a "bone stock" car anymore, but as I mentioned in another post there are NHRA stock LS1's setting records. For example, a '98 Camaro holds the C/FIA record of 10:68@124.20; an '02 Firebird holds the A/FIA record of 9:91@132.43.
I said "13's should be easily achievable".
But if it will make you happy I will retract my statement and remove 'major'.
"I think 13's should be easily achievable without any mods".
How's that?
Oh yes AND LS1 Camaro's and Firebirds are WAY underrated.
No arguments from me. I love 'F' bodies (especially older ones regardless of what they are rated at).
I personally don't care what manufacturers rate their engines at. If I don't like the power I have I add more. Even my truck has a blower on it. I can't remember when I had a vehicle that was 'bone stock' at least not for long.

[DarthD]

I interpreted your statement to mean that LS1s are 14 sec cars that can dip into the 13's with a few mods. I see that is not what you meant.

It is true that in bad conditions, bad traction, or a bad driver they will run 14's. I actually got a 14.6 one time when I dumped the clutch at 3000 rpms and spun hard all the way through first. I just wanted to see what would happen.

With a normal off idle launch, then stabbing the gas after the clutch is out, and granny shifting, my car will run 13.7s at around 105 in hot humid Texas.
I do not like to beat on my car as it is my daily driver.
My WS6 is also bone stock except for the 45lb SLP sub frame connectors and strut tower brace.

[S8ER01Z]

My car is bone stock and i ran 13.4 @ 104mph with a 2.1 60ft and 3200DA... It was at the MFBA Cordova Rental so I have plenty of witnesses. If someone would like they can come tear my car apart looking for mods. Be my guest.

Thanks for the links. I have been trying to find the first one for a while.

[GA Country Boy]

I'm convinced you should be running a lot faster than you are (according to the article you told us to read). Why would you think anybody would doubt you're in the 13's when all the other stockers are too? Especially when stock LS1 auto 'F' Bodies have set records in the 9's and 10's. (See my previous post) Maybe if you
had told us your "bone stock" car was running 8's we might be forgiven for being a little dubious, but not 13's.

[WishIHadAPantera]

Not hating, but I really have to call BS when someone says a "stock" LS1 ran 9's and 10's.... I think this is probably a gross misrepresentation of the word "stock" and giving the little kiddies out there some very misinformed statements to go spread around as they bench race...

Do you have any information as to what stock means? Does it mean stock internals? Because that's HUGELY different than "stock"? By that definition of stock the 4G63 import guys have gone nearly that fast...

Stock to me means stock exhaust, stock clutch, stock airbox, stock rearend, stock ECU. stock tires, etc... No factory car with those types of things stock is going to run 9's or 10's....

Your interpretation of 'stock' is a liitle different from NHRA's which defines 'stock' in TEN pages of rules in their rulebook. The National Hot Rod Association (NHRA) has been the premier sanctioning organization of drag racing for more than 50 years and sanctions more than 5,000 events annually in the USA and Canada.
The NHRA Stock class records I was referring to were:
A/FIA 9:91@132.43 05/15/06 Ryan McClanahan, Alto Loma, CA '02 Firebird
B/FIA 10:62 03/13/06 Frank Genovesi, Yorktown, NY '98 Firebird
C/FIA 10:68@124.20 04/04/06 Jack Matyas, Bethlehem, PA '98 Camaro

I'm very familiar with who the NHRA is.... Soooo, what is the summary of the 10 pages of what stock means? Or do I need to go look them up? Like I said, I wasn't hating, I just want to know what the definition of stock is so I don't have to listen to some tool telling his buddies that an LS1 will run 10s off the showroom floor because he saw it here...

NASCAR stands for National Association for Stock Car Auto Racing.... but if someone came on and said those cars were "stock" and the record for this or that was 200mph they would get laughed off the site... I realize the NHRA has a stock class, but the interpretation is grossly different than when people are talking about a car being stock here...

You're absolutely right. What is 'stock' to one person may not mean stock to somebody else. Everything is open to interpretation. As to the NHRA Rule Book,
I would hate to attempt to precis it down since it is so specific and technical
and any attempts to do so would just omit a bunch of stuff.
I can understand your thinking, because when I first got into drag racing I felt the same way "how could these cars possibly be stock" I kept asking myself (and others). Then I learned what is really involved in preparing a 'stock' car (and won a few trophies in the process). Many would not call some
stock cars 'stock'. (I have a friend who puts down considerably less rwhp than me, but gets to the other end a lot quicker, but these are not stock).

[cailey37]

Just my two cents but I always thought "Stock" was what you purchased off the show room floor...

[SSmoky01]

Cailey37, The whole "stock" car deal in Nascar is kinda like the "street" car deal in Drag racing at the track huh.

[GA Country Boy]

Cailey37, The whole "stock" car deal in Nascar is kinda like the "street" car deal in Drag racing at the track huh.

NHRA actually has more classes for "Stock" cars (46) than they do "Street" classes probably because it started as a 'grass roots' for street cars.
There is really only one 'Street' class (Super Street) although the track optional 'Super Pro','Pro' and 'Sportsman' classes could also be considered Street classes. In reality all the cars in the stock classes could be driven on the street and probably most of the 'Street' classes.

NASCAR on the other hand attempts to equalize the competition, and
as far as horsepower is concerned, NASCAR’s rules limit engine displacement, compression, carburetion, and the basic configuration and dimensions of the cylinder heads so no single vehicle manufacturer theoretically has a significant advantage over another. Not many would consider these cars 'Stock' the way we consider 'Stock' drag cars and probably would not be able to meet the rules to enter any of the "Stock' Drag Classes.

Well I know I can't walk onto a Chevrolet dealership and buy a 700hp "stock" car........my thought about a car being stock is just that......you've done nothing to it and it's as it was when it was built on the assembly line.......I mean hell....I tell people when they ask what's in my car all I have is a K&N Air Filter and chip.....:yup: I tell them that turbo sound is just a booster for the A/C.......:)

I definately should be running better than I am... I am not the best driver. :) I have had a few people tell me flat out my car isn't stock because I should be in the 14s... :Puke: .. My post was for those people...

Of course i have seen people claim their STOCK Fbody has gone 11s..and I saw shake my head... too much misinformation out there. :(

We had a big discussion in another thread about what is stock and what isn't and there are a lot of different opinions. IF you go by NHRA rules as to stock classes there are indeed 'stock' cars that are running 9's & 10's and will (sadly)
blow my NOT stock BLOWN car away!!! BUT I do agree with you about there being a lot of "misinformation" around. Unfortunately one problem with the internet is anybody can say anything they want true or false. (And many do)

Anyway I have to go back to work on my latest 'Go Fast' invention that will make you go much faster at little cost. I haven't come up with a name for it yet since 'meth' isn't new and wouldn't be good for marketing, but I'm thinking something like 'speed'...8-)

[Wesman]

so what is the real dyno to stock engine ls1 98-02

rwhp stock how much it do....

The M6's dyno around 290-300WHP, while the A4's dyno 270-280WHP. Many have dyno'd higher, but thats basically what you can expect from a stock car.

[HUNTER02SS]

Just got the car off the dyno a couple of hour's ago. It is a bone stock 02ss.
The result's, 309rwhp and 324 rwtq.It has 43000 miles on it.

m6 or a4? and what options did yours come with power wise?

[02Z]

2000 and 2001 Z28 M6 Bone stock (even paper filter still) both at around 3k, both were at 299-300RWHP. That is 6 runs between 2 cars on the same dyno. I would say pretty accurate.
