Crabs, Nice exhaust and a tune. It makes quite a difference.
It was my first time on a dyno it was pretty intimadating lol!

the number were alot lower then we all expected, my first pass was only like 178 or something but i was almost shaking i was so nervous being strapped into a dyno for the first time. the best we pulled that day was like 190 something. the intake temp was 49 degrees c and the humidity was 100% so that didnt help at all. i also dont think i was doing it right lol, i kept letting off at like 6k i didnt know if i was suposed too let it go at a certian time or let the limiter kick it, chalk it up too inexperince, nervousness, and being a natural blonde. We arent done with it anyways so im going too clear up if i did anything wrong this week when we go at it again. i was getting a bit of knock and we couldnt go any further until we put in some new plugs. I expect some better numbers when we go at it again later this week.

49* intake temp? I take it they didn't put a fan on your intake to at least simulate driving conditions?

Given that, 190 isn't totally horrible. That translates to approx. 232 at the crank, and I'm sure it would have been better had they gotten the intake temp down.

yeah i dont remember the exact number, it was 190 something we were expecting at least 200 to the wheels.

it was so hot and humid on the verge of a thunderstorm that the fan didnt do anything too cool it down.

we arent done yet either! and im going too take off my intake resonator before i go back it should help too cool it down.

It blocks the air now so TAKE IT OUT!!

My Dyno was 205....exhaust, intake, tune and all...I dont recall the temps
or conditions. A normal day I recall....

I think your 3.9 will do allot better. This a dyno tune or are you just dyno'in?
120 is about the temp if your standing still with no air. Once the car gets moving
it should drop at least half the difference to ambient air.

Ram air brings it almost to ambient temps.

*in my experince...

I should have taken it out before i even put the intake on, its double the work now.

It is a dyno tune, im sure with the intake resonator removed, new spark plugs, and a better day its going too produce alot better numbers.

I think I am laying off the gas too soon also. I get nervous when it gets close to the red I dont want too hurt my baby!

nooooo....the resonator is below the quarter. No need to touch the intake.
Take it out through your wheel well. Easy cheesy. Need a "how to"?

190? Wow thats disapointing for sure. I had my 06 GTP 6 speed dynoed after I put an intake, exhaust, and a jet performance module in similar conditions to yours hot, humid, elevation, no air moving in the shop (the front of my car was facing a wall) still ended up with okay numbers 214.76 HP and 211.43 at the wheels which puts it at 246.97 at the crank, however there is a website you can goto and it will calculate based on the temp, humidy, baramteric pressure, and elevation. When I used it it gave me numbers of 225.60 HP at the wheels which puts it at about 263HP at the crank. But this shoudl give you some idea of what numbers you should be able to get.
