question about dynos
Friday i ran my friends modded c6 z06 on 17lbs and pulled by a car. Later on i took it to his dyno where he made 498 and i figured what the hell and dyno'd the car and i was surprised that it made only 448 on the same pounds (if you look at my signature i did 478).
The dyno where i tunned at (for the 478) was a portable one that you lay on the ground with a ramp to roll on the 2 dyno wheels that go between my rear wheel, the one where me and the z06 did was a actual dyno jet with one wheel under the rear tire.
so different dyno's really make different #'s? is it the wheel used on the dyno? Or maybe the computer?

Will work for horsepower
I understand dynos use diffrent corection factors. I have dynoed on a dyno pac at 420 at 16 lbs. and dynoed 403 at 20 lbs on a superflow! I was disapointed and wondered what was wrong but after checking et calcutator at the 403 h/p my car ran within 1/10 th of the listed time. I run 10.8-10.9 at 403 h/p if i had 478 h/p it would be close to 10.2-10.3. So if the h/p does not match et's the dyno could be wrong or your a lousey driver! Someone should know more about this as i would like to know!

Run a set of 10.5 et streets at about 15 psi air pressure and play with the launck rpm's until to find were it goes and dosent bog. For me its about 7800 rpm's. Its confusing when you dyno 403 h/p but run this well it makes you wonder if everyone with big h/p numbers are right or if your just good with a good package. Dont get me wrong im proud of the car but im not bragging im just confused!

Why the hell do you have 3.90's? Perhaps thats PART of the reason your car falls on its face in 5th.
Also, your stories are all confusing and way to different for me to believe, so I'll just say good luck in one day pulling the vette.
BTW, White Z, AWESOME car!

dynos read differently because they're actually designed and built differently. there are a ton of factors that go into them and the numbers they produce. that's why the only way to compare your numbers is to do it on the same type of dyno.

You guys over in the US always seem to get higher dyno figures than over here in the UK, even with identical mods on our cars...
e.g T04R on a street port with FMIC, De-Cat, 550cc & 1680cc inj, in the US making 450rwhp, would probably only make 400 rwhp at 15 psi in the UK...

The uncorrected numbers from any Dynojet are usually dead-on accurate in regards to what your car did at that time on that day at those conditions.
