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

[GeeTee]

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?

[2KTA]

well thats pretty close to actual rwhp for a stock ls-1... might even be a little less, and the 1/4 mile time would range from mid 13's to low 14's from what i have seen run

[BlackHawk T/A]

A4 ~290-300rwhp
M6 ~310-320rwhp

1/4 Mile: 13.2-13.4 for both cars @ 104-106mph

[LS1-450]

Stock LS1 will run in the 13's w/ good driving (launch mainly). Half the guys driving one would probably run 14's, but, that would have nothing to do w/ the engine. Should dyno between 280 & 300 rwhp stock. With an intake alone would likely dyno over 300 rwhp.

[Sarge]

The GenIII LS1's are consistently dyno'ing in the high 280's to the rear wheels...the LS2's are as consistent in the low 300's RWHP.

[third_shift|studios]

well thats pretty close to actual rwhp for a stock ls-1... might even be a little lessummmm no.


A4 ~290-300rwhp
M6 ~310-320rwhp

1/4 Mile: 13.2-13.4 for both cars @ 104-106mphummmmm, YEP! :yup:

[GatorSS]

My '00 SS dyno'd at 306 RWHP bone stock when it was new (about 1,500 miles on it at the time of dyno). Needless to say, it wasn't long after I bought it that it lost it's bone stock classification. None of my other LSX toys were dyno'd while still stock.

1/4 Mile: 13.2-13.4 for both cars @ 104-106mph


This is accurate info. That crap they are telling you is wrong. Maybe if you don't know how to drive your stock LS1 won't do better than a 14sec 1/4 mile but anyone halfway experienced should pull exactly what Black Hawk said.

My stock except aluminum flywheel and k&n airfilter 98 forumla had 313rwhp and 322 FTlbs of torque at 110,000 miles.

[WishIHadAPantera]

Those are times and hp from sea-level, at a place like Bandimere the times are probably fairly accurate.

[gnomee]

Those times are accurate for Tulsa area. We are at about 740 feet above sea level.

I wonder if that guy on the other board is thinking LT1 instead of LS1

[Mr. Luos]

I love Bandimere. Very nice track.
Just the DA ALWAYS sucks.

I was last there in April. DA was 8200+.
Ran a 14.1 at 105.23. Short times SUCKED bad. Clutch wouldn't allow any kind of launch, so I rolled it off the line.
Stock on a good weather day LS1 cars run mid-upper 14's. Bad day....some people have problems staying in the 14's. :think:

[BlackTAWS6]

With the whole thing about running in the low to mid 14's, I can believe that on some. It isn't always the drive I think. The location I feel is key, too. I ran mine the 6th day I had it at Little River in Temple, TX and came out something like 13.5 - 13.7, I really dont remember exacts, but, when I went to LACR in Palmdale, CA on a Wednesday (Test and Tune night, with no track prep) The best I could pull was only a 13.8 with some intake and exhaust, so to me the low 14's are possible.

[BlackTAWS6]

Also, stock I did dyno over 300 rwhp, something like GatorSS

I'm not giving the car any more than it deserves. If you can hook that's what they run, plane and simple.

[Billz90L98]

hey guys......My wifes 2000 RAM-AIR WS6 TA ran a 13.4 bone stock....even the air cleaner was stock. I have also seen a stock LS1 run a 13 flat at the track......

[Billz90L98]

yeah.....and my 90 5.7 TPI is faster than her car......and its only 215 rwhp and 338 rwtq.

[bigjay]

sorry, i stand corrected, i just called him, it was a 13.1@104 and the 12.86 was 108, all these numbers floating around in my head get mixed up sometimes.. especially when its not my car. it did however g-tech a 13.2 @110.. lol.. ya right they are accurate to a 1/10th of a second but the MPH is WAY off.

[area51m7700]

i ran a 13.2 at 104 in a stock 1le

[02z28ls1]

I think the 1/4 mile times vary a great deal cause of atmospheric conditions and traction and driver skill/guts.that's why you line 'em up and run 'em side by side.If they ran the same times every time you wouldn't have to run 'em.I've seen run offs in GM High Tech magazine where a stock motor LS1 with a sharp chassis tune ran mid 11's-no BS-aftermarket rear suspension stuff and an airbag in the rear spring and a girl driving!The mag guys were there supervising the runs so no fish stories-look at back issues.

I race at 5800 feet up. Bandimere.

Stock LS1 F-Body's seem to run upper 14's. A couple get mid 14's. Not seen one deep into the 14's without a couple mods.

Gee I was finally correct for once..........:think:

Except for the nun part, of course.....:)

Whats a dyno run show at that altitude for a stock LS1.??

Have fun......

[Mr. Luos]

Most dyno's show corrected numbers.
I did have a non-corrected graph printed out once though.

I made 376.8 RWHP and actual was right around 320 RWHP.

The one time I had it printed out was before cam....284.0 RWHP 290.9 ft/pounds un-corrected.
Corrected numbers.....335.3 RWHP and 343.4 ft/pounds. Correction factor tends to be around 1.20-1.25.

WOW that is quite significant, stock LS1 would be lucky to run 14's at 6,000 feet.:hyper:

Thanks

Have fun

[Mr. Luos]

Tell me about it.

I should be in the 12's here at the beginning of next season though!

[svt_eater]

I went to the track stock 2 years ago with about 15000kms on my Firehawk T/A and ran consistent 13.6's. I did about a dozen runs in way to short of a time and the clutch started to smell on the last run so I kind of took the hint.

It sure took a good beating. It was about 40C(104F) and really humid. I still ran a 13.8 on my second last run with a buddy in the car.

That was at St. Thomas in Ontario, Canada. Not sure of the elevation, but not likely over 500ft I don't think.

I've heard that most are dynoing stock between 300-310, with some factory freaks at up to 325-330 at the wheels. I've just done the SLP bellows kit and all Royal Purple fluids in my M6 and the car feels like its gained a good 15-20HP...probably in my head! I've not made it to the dyno as yet. $75 to find out what it puts down seems a little pricey to me...although I do think bragging rights may have some worth.:yup:

[Zboner]

$75 is great price around here its $100 and for specials its $65.

[BlackHawk T/A]

I don't think i'll even bother with going to a Dyno just to get numbers...an A4 with a converter isn't going to be very impressive anyway.

[Bob'sWS6]

I didn't dyno my car stock. Right now it's pushing 351whp w/ a Z06 cam and a few bolt ons. Stock my understanding is that LS1's typically dyno as follows:

98-00 = 272-300whp (Depends on whether equipped w/ A4 or M6)
01-02 = 282-310whp (ditto)

The dyno numbers don't mean squat though, as obviously track times are what people want. Most bone stock LS1's run high 13's in a decent drivers hands (Dunno what downhill tracks, besides E Town, that people are driving at, but most tracks aren't exactly at sea level). In a sucky drivers hands they will run 14's. Of course there are freaks, such as the guys making 320+ whp stock, which is why there may be cars in the low 13's, but that isn't on average from what i've seen at Speedway by a long shot (And i've been there for years).

[BlackHawk T/A]

Mine is probably one of them at the moment...I can't even get traction from a 25% throttle takeoff...even as I ease into it the tires go up in smoke at about 50-75% throttle at 25mph...and I haven't even gotten into it yet :burnout:

But not for long :yup:

[Bob'sWS6]

Yeah, i'm not stating that there aren't low 13 sec. LS1's, but they are few and far between. Not everyone of them puts down 310-325 whp stock. I read of some dude in a WS6 that put down 330 whp stock. That's almost as much as I have in my Z06 cammed WS6. I feel cheated.

(Typo, don't type at night

[BlackHawk T/A]

Yeah...I meant the comment about the high 13s maybe even 14s due to poor traction though.

[Killer_bluebird]

My Wife's 00 A4 Z28 did a best 13.4 at 104mph with only a K&N filter. Here is the Dyno:
http://i6.photobucket.com/albums/y206/killer_bluebird/05Z28Dyno.jpg

My car is a freak and Dynoed 332.3 with a lid, K&N, descreened maft and 160 stat. See below the first run was with HPP3 (It robbed me almost 5hp to the wheels) My best 1/4 mile was 13.2 at 106mph on street tires with 2.1-2.2 60".

[Bob'sWS6]

Well having a 6 speed makes it hard to get outta the hole. That is why you only ran a 13.2 sec. 1/4 mile at 106 mph. I'm running a 13.1 sec. 1/4 mile at 109mph w/ 351whp at a 1300 ft elevation track. Of course I know i've got 12's in my car at the track, but i'm not the greatest driver.

[Killer_bluebird]

Well having a 6 speed makes it hard to get outta the hole. That is why you only ran a 13.2 sec. 1/4 mile at 106 mph.

Yup I Know. The car has 12's written all over, unfortunately the driver doesn't:lmao: . I just need a nice set of Drag radials, but since I only go to the Dragstrip once or twice a year I can't justify getting the them. Maybe next year after the cam swap.

[Mike's02Z28M6]

Dyno'd w/lid & catback which shoulda been worth + 10-15 rwhp combined.

[Killer]

bonestock ls1 will dyno from 310-325rwhp run 13's or high 12's

So to make a long story short, our cars are fucking SICK no matter what! Im sorry i just had to say that, and thats how i honestly feel.

[2000 Camaro SS]

Just dynoed mine yesterday. I have a 2000 Camaro SS convertible with 35K miles with a Borla catback exhaust and a K&N air filter. Took it up to 5600rpm 4th gear pull and got 314.4 hp and 323.5 tq.

[GatorSS]

They are not kidding. It's all about air density and elevation makes a HUGE difference, much more so than even the hottest temperatures in Florida. Try your car at 6,000 feet above sea level. It will be much slower than in Florida, which is comparatively very near sea level.

Don't hack up people's driving too much before understanding the circumstances. Take a smoker from Florida up to the top of a 6000 ft mountain peak and see how their breathing is. I'm sure you've heard how Olympians have to train in the environment they are competing in to acheive peak performance. It's no different for your combustion engine.

The density of oxygen is much lower at 6000 ft. When there is less oxygen to force in, it is impossible to get the same power out as the oxygen is what makes the power. That's also how NO2 works...and turbo's...and superchargers, they all feeds more oxygen into your combustion chamber.

Other factors like moisture, temperature, track temperature, tire pressure, rim size, weight, transmission losses, differential ratio, gear ratios, shift speed, launch technique, tire quality, etc, etc...it's a long list. Yes, some people are better track drivers than others, but there are many other factors. I'm just saying don't paint the world with too wide of a brush.

[RedRamAir2000]

i did factor those in, car shouldnt run 14s

how do ya figure a car shouldnt run 14s when lets say the driver has never drivin at the strip before and the quickest car hes ever drivin was a beretta GTZ...obviously it takes some practice to start runnin those numbers....just like tellin someone to go drive a stick who has never drivin one before..takes some time...i got no prob sayin my first run was a 14 flat...kind of like me hoppin on a dirt bike and never been on one and someone say now you should be able to jump that 150ft gap

Don't forget SS and some Z28's have different rear end ratios (Performance ratio was optional in Z28's standard in SS). Also some of the SLP stuff will change performance. Are you including that stuff when you say "stock"?

wasnt sure really where to post my question where i would get the best results.... so heres the big question Im thinking about puting a set of cylinder heads and a nice .550 .580 lift camshaft in my car..:drivin: .. I thing thats been floating around.. I hear you have to pull your motor to be able to put the camshaft in? True? Not True? Also could you just pull your radiator out and your front bumer and put the camshaft in then?

[ibanez7]

Damn I can’t believe how many of you forgot to mention that 98-2000 Ls1 dyno completely different then 2001-2002 ls1.

98-2000 ls1 do have a hard time breaking 300rwhp stock. Some as low as 287 some as high as 310

01-02 should consistently be around 315rwhp stock. Some as low as 300 some as high as 330

With about 13% drive-train loss:
98-2000 ls1 crank hp about 325 about!
01-2002 ls1 crank hp about 340 about!

Drive-train loss: GMHTPM rates drivetrain loss at 13%, many others take it has high as 18%. Yes the difference between A4 and M6 plays a part too, M6 suffer less loss.

Yes dyno numbers do range and vary, due too many factors. The two biggest factors being; GMs tolerance or should I say “loose slop”, and the dyno machine.

GM engine geometric tolerance and slop:
The difference between an F-body and a hand built Lamborghini is tolerance slop. Precision cost $$$$ during fabrication. For sake of numbers GM designs to a +/- .005 and lambo builds to +/- .00005. That slop by GM equates to cheaper cost cars and inconsistencies.

Hence why there are factory freaks and extreme swings from low to high on dyno machines(even if is the same dyno machine). Every engine breaks in differently and responds differently.

Dyno Machines:
Eddys and Mustang dyno always show lower numbers then dyno-jet, it’s a know fact!

No matter where you look from here at ls1.com to heavy knowledge based ls1tech.com to GM High tech performance magazine, dyno number range by an extreme amount. Dyno numbers are just a good reference point to see the power difference with new parts.

As far as 1/4 mile times, ls1 01-02 F-BODYS have been know to break into the 12s while completely stock, while some run low 14’s.
It depends on the driver and traction. With average traction and an average (performance driver) should see consistent low 13s. With a great driver you should see 12s in an m6 too.

Also f-body ls1 DO put out the same hp as ls1 vettes.

My 01 z28 m6.
I was able to run 12.9x at Great Lakes Drag, with just a lid and deflated rear tires.
With a lid, LTs, ORY I dynoed on a dyno jet, 347rwhp and 356rwtq.

Damn I can’t believe how many of you forgot to mention that 98-2000 Ls1 dyno completely different then 2001-2002 ls1.

98-2000 ls1 do have a hard time breaking 300rwhp stock. Some as low as 287 some as high as 310

01-02 should consistently be around 315rwhp stock. Some as low as 300 some as high as 330

With about 13% drive-train loss:
98-2000 ls1 crank hp about 325 about!
01-2002 ls1 crank hp about 340 about!

Drive-train loss: GMHTPM rates drivetrain loss at 13%, many others take it has high as 18%. Yes the difference between A4 and M6 plays a part too, M6 suffer less loss.

Yes dyno numbers do range and vary, due too many factors. The two biggest factors being; GMs tolerance or should I say “loose slop”, and the dyno machine.

GM engine geometric tolerance and slop:
The difference between an F-body and a hand built Lamborghini is tolerance slop. Precision cost $$$$ during fabrication. For sake of numbers GM designs to a +/- .005 and lambo builds to +/- .00005. That slop by GM equates to cheaper cost cars and inconsistencies.

Hence why there are factory freaks and extreme swings from low to high on dyno machines(even if is the same dyno machine). Every engine breaks in differently and responds differently.

That has to be about the best writeup I've seen... thanks for taking the time to post it!

[Killer_bluebird]

If I remmember correctly Driveline loss is in the 13% range for Manual 6 speed, 15% for an Automatic 4 speed and 18% if you are a Mustang!:lol:

I ran a 13.376@104.36 in my 2000 Z28 A4 last night

I was racing my friend in his 2005 C6 A4 and i beat him every time. His best was 13.6@106 WITH A 2.0?? 60 ft time. Im not sure what his problem but I think he should have beat me.

When my car was stock it did 13.5@102 Since then i have added MTI clear lid, Blue MAF ends, K&N filter and free ram air mod to run the 13.376@104


My next mod will be a good cat back with exhaust cut out, maybe a 13 flat!!!!!!!!!

I am very happy with how my car is running

[svt_eater]

Kudo's Pantera! Sometimes someone just needs to set things straight. You make a great point.

Nice numbers tx...ls1. Did your buddy have his traction control on or something? I'd be taking my 'vette back if I ran a measly 13.6. Some of my best times were with some decent wheelspin off the line, so it is not likely to be that. I would guess a 1.8 60' would be more what I'd be looking for in that.

[tx77015ls1]

he said he had it off. My dad had a 99 Cadillac Deville it semed like when i had the traction control off it was realy on cuz it would just bog down off the line and when it was on thats when it would spin the tires just right and would get the best times and not bog down.

dont know what he deal was but maybe the same deal with my friends 05 vette

The Cadillac ran a 15.4@90

no problem and thank you!

[Nate00SS]

I race at 5800 feet up. Bandimere.

Stock LS1 F-Body's seem to run upper 14's. A couple get mid 14's. Not seen one deep into the 14's without a couple mods.

:yup:
He is right on. I ran my bone stock 00 SS m6 and turned a 14.7 @ 98.9mph. That's spinning pretty good, I have a very hard tire, I like them to last more than a month. A lot of the a4's run better et's. Not many people understand that running this high above sea level really kills our ability to make big power.

[tx77015ls1]

I love Houston Raceway Park. Its 30ft above see level and cars seem to run great there. They also keep the track in perfect condition

[Nate00SS]

my 2000 a4 ram air with hooker 1 3/4 full leanth headers and slp loadmouth. ran 12.70 at 111 all stock just exhaust


First of all that's not ALL STOCK. Plus you drive an A4. Like that's hard. try to run a 1.9 sec. 60' in a M6 with street tires at the track. I don't think anyone can. Unless you slip the shit out of your clutch. Then i still don't know if it is possible. I invite you to come race at Bandimere. You won't run better than a 13.5. not a chance.

[NVmySSMaro]

No dyno #'s but my 2000 SS M6 went 13.22 at 106.7 mph with a 2.08 60ft fading clutch. but that was with LT's, Cat back, 3.73's, air intake, Power programmer. no idea on the elevation... i think i got one of the dogs as far as the avg LS1's go. :dunno:

Damn

303 rwhp with lid 336 rwhp with headers ls6 intake and magnaflow on a MUSTANG DYNO (99SS M6)
? why so much higher numbers with 2001/2002 ls1 ? the ls6 intake.

[damac]

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.

[2000z28]

i dynoed my 2000 z28 with a chip and flowmaster exhaust at torque freaks in Portland, OR and they said my car was only getting 287 rwhp with 289 torque, and then last week i ran a 13.5 1/4 mile at 103 mph, i was wondering if maybe their dyno isnt accurate? has anyone else gotten dyno numbers like that ?

[Mike KK]

What should my 98 Z28 with 3.23 gears, built tranny, 2500 converter, energy mount, K+N filter, headers, Y-pipe, Loudmouth II exhaust, racetronix fuel pump, vette wheels 275s/315s and eibach springs run?

[DarthD]

2000z28, what kind of dyno was it?
