View Full Version : factory freak bolt on dyno!

car dynoed : 2001 camaro z28 m6 (3.42 rear)
miles 106,xxx
power mods:
all bolt-ons
Exhaust:
hookers LTs
ORY - no cats!
flowmaster muffler
flowtech cutout (open)
Intake
ported/polished throttle body
bumpstop mod
Fernco smooth bellow
SLP Lid
SLP MAF
Engine:
SLP Underdrive Pulley
Its a full bolt-on car.
First off thanks to Tony and the guys at OUTLAW for getting my car on their mustang dyno.
Now as far as the dyno numbers.
357 rwtq (not weather corrected)
352 rwhp (not weather corrected)
351 rwtq (weather corrected)
346 rwhp (weather corrected)
Since mustang dynos are more accurate then dynojets and show lower numbers, everyone expected my car to be at most 330 for a bolt-on f-body, which is the average for bolt-on fbods on a mustang dyno
but nope! I am very pleased with these numbers as they are extremely strong.
Last winter I dynoed the same numbers on a dynojet dyno, with a couple of less bolt-ons (underdrive pulley, bumpstop, ported throttlebody, etc). So yeah i was expecting lower numbers on the mustang dyno.
On a dyno jet my car is at 376rwhp.
Again both dyno reflect that my car is about 20+rwhp over the norm for bolt-on f-bodys!

Ok can someone PLEASE explain the difference between a dyno jet and a mustang dyno?
ibanez7
10-30-2006, 11:38 AM
a mustang dyno reads/measures differently. Its a more real world application, more accurate.
for the situation I posted above, dynojets usually read about 20 hp more.
which is why people like dyno jet numbers, looks like their car is making more hp then it really is.

10-30-2006, 11:52 AM
agree with you but you r modded
yes but all bolton mod f-bods usually dyno around 330 on a mustang dyno and 350 on a dyno jet with the exact same mods I have..
my numbers are 27hp higher! which makes me feel lucky for getting a strong engine

with full bolt ons on a mustang dyno i made 380 rwhp but the guy said the dyno was off and told me it was more like (360 rwhp)----which was still good for bolt ons------ bolt ons only i would hang with my buddies 04 cobra with 440 rwhp on a dyno jet-----

you stated the dyno was off, so what was the PAU set at and what was the vehicle weight at?

the PAU is the resistance given to your car...
It should be listed on your dyno sheet!

hmm that is still good numbers for flywheel.
flywheel to ground can be up to an 18% difference. Higher percentage for A4
My numbers where RWHP which equates to about 420 at the crank.

I don't know about calling a mustang dyno "more accurate." the only difference is that mustang dyno's apply resistance at the rollers and dynojets spin freely. I would use "more accurate" a little less loosly, most people use dynojets and so most numbers you hear are dynojet numbers, mustang dyno numbers are the oddball numbers that you don't hear near as often. It's WAY too easy to mess up a dyno run on a mustang dyno, applying too much or too little resistance etc. . .a dynojet is much more consistent with it's numbers.

to say a mustang dyno is more accurate, would be inaccurate. mustang dynos aren't any more accurate than a dynojet. i did a test on a mustang dyno. changed the vehicle weight and gained 5 rwhp with no changes to the car.
mustang dynos use an eddy brake to simulate rolling resistance. dynojets usually dont have one. you can buy an eddy brake unit for the dynojet. so, if i go and dyno on a dynojet with an eddy brake, which one is 'more' accurate now?
BTW, NASCAR uses dynojet to compare team cars to qualify for racing. not mustang dyno.
ibanez7
11-08-2006, 08:11 AM
I feel that mustang dynos are more accurate to real world application.
The PAU was set in the high 500s and the wieght was set to the stock weight of 37xx
nonetheless on the dynojet I dynoed just under 380rwhp.
three pulls on the mustang dyno was consistantly around 357
three pulls on the dynojet dyno was consistantly around 376
and my car trapped 116 at the track
so yeah I would chalk up this ls1 as a very healthy bolt on runner!

What was the ET?
The only problem I have with your statement is that I know a few people who are making just like you said, about 20hp less than you. But they are doing it with 12bolt and 9" rears which cost you, get this, about 20hp. So I am also going with the thought that you are making average horsepower for an 01/02 f-body.

12-13-2006, 02:21 PM
Did you actually dyno 376whp on a Dynojet or are you estimating? If you are, is 116mph indicative of 370-380whp?
joezee
12-17-2006, 11:54 AM
not bashing, but...116 mph IS 375 rwhp , which would give a factory rating of 425 hp or so............so how does intake and exaust EVER add 75 hp ?????
unless he bought the car new, ...sounds like a mild cam or heads or ????
again all stock ls1s trap 105 to 110 at the freakish most,.....bolt on car running 116 ? am I missing anything ? most heads & cam cars WITH bolt ons run 115 to 120 right?? not bashing , just curious.

How is it a "Factory Freak" when it is HEAVILY modded?? A Factory freak is when the car puts down above average #'s while STOCK, not modded like yours is. Nice numbers though.

ibanez7, you are not alone. :) I tuned this car with similar mods as your's, although with cats and on a DynaPack Dyno. If tuned right, some late production F-Bodies are putting down great numbers.

I know you're talking about an M6, but 116 mph. i have an A4 with a factory converter/125 hp of nitrous/4.11 gears, 1.7x 60' with and 11.7x 1/4 mile trapping @ 117 mph spraying out of the hole. I haven't ever had it on a dyno, but would guess I am around 430-440 rwhp on the jug.

What was your E.T.?
ProwlerZ
12-23-2006, 08:58 PM
Your #s look about right to me. Full bolt on usually nets between 350-375 on a dynojet, so that gives you approximately 330-365 on a load bearing "mustang" dyno.
Oh, and btw, a bolt on LS1 ain't keeping up with a Cobra putting down 440 on a dynojet. If so, something was going real wrong with the pony.

Well he is FULL bolt-on, not JUST headers, tune. I dunno, I think the trap seems legit. A little on the fast side for most but overall seems right. Although, my friends cammed TA went 117mph and he was full-bolt on with some weigh reduction.

no offense bro, the dyno numbers seems legit and all but really you shouldnt have boasted the 116 trap.. thats an EASY 11 second time.
http://i125.photobucket.com/albums/p42/juiced99ws6/Timeslip.jpg
(im on left) this run was made with full bolt ons and spraying 100 shot from the 1/8 mile marker. So you can get a little taste of what a 116 trap would do

oh and for more comparison.. my car has never been dynoed but the car on the right is an 05 GTO that put down roughly 370rwhp on a dynojet. granted its heavier and has torque management out the ass but he still only trapped 100...

12-31-2006, 12:11 PM
i don't think anyone doubts his dyno # , after all dynos are great for tuning but vary wildly from one to another...BUT 116 mph with his mods NEEDS more explaining......but he posted a couple times and doesn't say anything , so....I say he got the car with a cam or heads, or both.......
3500lb cars running 116 are making 425-450 factory rated hp......
his car came with 350hp....75-100hp with his mods.....BULL.
juiced99ws6
12-31-2006, 03:40 PM
he just wont give an et... ET and Trap speeds are just as consistant as dynos. Different dynos yield different result and different tracks do as well so unless you are running all the same conditions then times/ dyno numbers cant really compare cars. Only way to compare is to line them up side by side. He could very well have pulled 116 trap but i wanna see his damned time! :lol:

I don't know the person involved, and cannot vouch one way or the other for what he/she is claiming. However...
Dyno's are for tuning. Nothing more, nothing less. Doesn't matter if it is a Mustang Dyno, Dynojet, or Dynosaur - they are a tuning tool. Also, you cannot make a blanket statement that a Mustang dyno reads xxxx HP higher/lower than a dynojet. It is a load-bearing dyno, and will read differently depending upon the inputs by the operator.
116 mph is possible with a bolt-on LS1. Not common, would probably need very good air/track, and some lightening of the car would probably be necessary, but it is not totally unheard of.
You cannot make a blanket statement that "xxx RWHP is needed to run xxx MPH in the 1/4 mile". There are too many other factors to consider, most importantly vehicle weight, and also things like gearing, track, weather, driver skill, etc.

You can get a very general idea of what kind of power you are making based on your 1/4 mile MPH and vehicle weight. Be advised that there are many variables that can change this, including air quality, track condition, track elevation, driver skill, etc, etc. However, the formula below will give you a pretty good guestimate:
HP = (mph/234)^3 * Weight
I don't know your weight, but I'd guess around 3650 lbs with driver. Using that and 111 mph, you come up with the following:
111/234 = .474
.474 ^3 = .1065
.1065 * 3650 = 389 HP.
Note that this is flywheel HP. A typical T56 street car should lose ~50 HP going from the flywheel to the rear wheels, giving you ~339 RWHP.

I knew there was a formula out there, I remember that the MPH usually reflects HP for a given weight and the E.T. represents the traction factor, which in my case sucks!
Others have said that the track I goto is poorly taken care of, but its the only one i goto because its only 25 mins away. Still fun though!:nana:
