C5 stock dyno numbers??
Hey everyone.. I was looking for stock dyno numbers on C5's.. I tried using the search and typed in stock dyno and it didnt come up with anything..
I would like to know some stock dyno numbers if anyone could help me out.. Preferrably numbers you or a friend has got.. And if it was auto or manual.
Some guy on a different board was talking about it and said a C5 usually dynos less then a m6 camaro because the c5 has IRS!!
Is that BS? I wanted to call him dumb but I dont know for sure?? I know vettes weight a little less and have higher HP ratings but I would guess it dynos a little more then a M6 camaro(all ls1's)
Thanks for any help you can give me.. I love C5's and hope to have a C5 or a Z06 within a yr or 2..
Thanks again
Ryan

Ryan,
See my dyno results in my sig (Dyno numbers were achieved when my car was bone-stock.) Remember though that correction factors for dynos are not all the same. My numbers came from an STD-corrected Dynojet, whereas SAE-correction generally results in lower numbers. I'm guessing that my RWHP would have been about 308, had the dyno been SAE corrected. Mustanf dynos are said to produce lower numbers.

LS1 6 speeds usually pull 308-318
LS1 Autos usually pull 290-300
LS6's are 350-360

We have a Mustang MD1750. MD #'s are always lower due to the design of the dyno (full load bearing).
We typicaly find inhouse stock A4 will run 255-265 and M6 will run 265-275.
As for the F-bodys..Yes..even with less flywheel hp they will typically be in the same hp range as the vettes. They have significantly less driveline loss's.

Re: C5 stock dyno numbers??
So a C5 should have more HP then a Camaro with the ls1 then correct?
From what ive seen and heard the camaros usually pull somewhere between 280-300rwhp if I am thinking correctly..
Anyone else care to share theres?
Thanks to everyone that replied so far..

Hey man. thanks, your saying camaros and c5's have similar dyno #'s and the camaro has less drivetrain loss?? Is that correct??
Thanks

Re: C5 stock dyno numbers?? (jfss3bat)
What you were reading on the other board is true. LS1 Fbodys (Camaros & Firebirds) usually dyno a little higher than LS1 Corvettes. The engines that went in both were basically the same, just the F-bods were underrated and have less drivetrain loss. That said the vet with an equal driver will be faster given its 300lb weight advantage over the typical F-body.

Re: C5 stock dyno numbers??
See I kind of agree.. Dynos are used best for tuning.. But on the other hand I like them as long as they are the same one.. Say you pull 300rwhp at one place then add an intake exhaust and go to a different dyno and pull 305rwhp.. Now you would think you would have more hp then that..
As long as its the same dyno you can get a good idea of what mods are worth the money...
Thanks guys

Dave, did you get your Vett dyno'ed in SD? If so who did it and how much did it cost? I'm thinking about getting mine done prior to making any mods.

Re: C5 stock dyno numbers?? (olly281)
Bone Stock with the original air filter and exhaust my 97 dyno'ed at 298 HP in Aug. 99. The car had about 10K miles on it at the time. A year later I got 296 on the same dyno at the same place.
As mentioned above dyno runs are best used to determine the effects of tuning. But even then they not provide useful data. They Dynojet unit is accurate to within +- 1%. At 300 HP this is a potential 6 HP range. If you only see changes in HP with some mods you may not be getting any improvements. For example, given a car in the 300 HP range going from 297 to 303 doesn't prove anything since that is the margin of error. You could have gotten that difference from one run to another without any changes. The only way to tell is to make multiple runs at each data point so you can average out the error. That costs a lot of money at $75 for 3 pulls.

Re: C5 stock dyno numbers?? (Bill Dearborn)
Just an FYI:
Chassis Dyno is a representation of engine crankshaft power minus all drivetrain losses.
Gearing is not accounted for (*except for inertia with a higher ratio*); meaning that sticking your car in 2nd, or 4th gear will produce relatively equal power curves and peaks at certain RPM.
Put equal Vettes side by side, but change the gear ratios in one. Use 3.23 and 3.73 for example (before anyone flames me, let's pretend the gears are matched to the driveline and motor :) ).
The car with 3.73 will have a higher torque multiplier and plant more force to the ground...yet the dyno wont show the multiplier.
That will explain (for the most part) why lower HP cars sometimes out perform higher power cars. It's all in the gearing (tranmission/differential/Tire OD)
