Hey Guys, Well we finally got this thing on the dyno after ironing out all the details. The car made 622 AWHP @ 19psi on 93 pump with stock cams! When we tried to bring the car up past 20psi we ran into some missfires and took a break to check the front plugs. Everything looked fine except I could have gone a bit lower on the gap which would have probably cleared up the missfire for some more boost. We regaped the front plugs and were able to get on clean pull before the rear plugs started to miss and by then it was too late to pull the mani for the rear plugs. @ 20psi the car made 655 AWHP, and then we called it a day...


We are going to change the plugs and give it another go, we might get lucky and put down some higher boost numbers before we run out of ignition. Does anyone know what the output of the coils are as well as the stock dwell time?

Here are some vids and the dyno graphs!!!!! ENJOY...

P.S. thanks Brian and Carl for all your help with the cams and the MIVEC questions. I will probably need a set of cams to optimize this set up so i'll be giving you a call soon Carl, just want to see what is the max we can get out of the stockers before i change over...

im sure you know a lot more about all this turbo stuff than i do.. since ive never had a car with one. but i do know someone with a twin turbo vr4 3000gt pushing 900hp to the wheels.. so what have you not done to be hitting at least that with a 3.7L?
i think the 3kgt only has a 3L
no disrespect, im just wondering why the bigger engine isnt putting out a lot more power.

Your probably taking about Ray Pampena? He is the guy who tuned the car on these runs...Well, with this new set up it is going to be interesteing to see what the final results are. Right now the only things that would hold this car back from those high AWHP numbers are cams and ignition, which are both stock on my car...

so far 540@19psi and 552 @20 which is pretty good..Keep in mind that these are some huge turbo's so we really wont see the effect until we crank up the boost....Just the fact that i can spool these turbos at around 5400-5700 full boost is sick...

My thing is why didn't u just stroke the 3.0 to the 3.5 I heard about? And just go with the TD05 TT setup? About the same power I would guess and ALOT less work. But if u wanted to be the first at something and wanted a play thing then u did it and it is badass.
