Thread: Twincharged GTP dyno video

Finally got the car tuned and on the dyno today.
Twincharged GTP Dyno - YouTube

Made 410whp and 413wtq @ 17psi with an unlocked converter (HP Tuners apparently can't lock it in third gear in the Grand Prixs), and 225 Intake Air Temps. Steve (tuner) and Kevin (dyno driver) were scared ****less when the car moved around on the dyno like it did (I told them to cross the straps, but they said it was fine).

nice!

Awesome man!

i got scared for them lol.. one or two inches from fckuing chit up nice numbers tho

Very nice! What turbo are you running?

I just can't stop drooling.

93 Pump Gas. I know I know...E85 is awesome, but it's just not plentiful around where I live.

The first pull it did come off a little and smoked the driver side tire.

I bought the motor setup already built and in a 4-door GTP from a guy in Mississippi. He was running this setup on a stock trans. I bought the car and swapped the motor and turbo kit to my 2-door with a built transmission. I'm planning on selling the 4-door with my original motor.

Bought 4-door for $6k and selling the 4-door for $4500-$5000. Basically, I bought a 3000 mile L32 and the brand new kit for whatever the difference is in my buying and selling prices.

Oddly, I like this

soo after it smoked the tires.. they tried it again.. without re strapping the car? i dont think they like you

sketchy....






nice numbers

Dont know why, but I've always wanted to see a twincharged GP. Thank you for doing this..

I honestly got scared when I saw the car start to move, cause I've seen first hand cars slipping off the dyno.


If you can (not sure if you have a build thread going or not) I'd love to get some pictures of the engine.

Also, what's your intercooler setup?

They kept tightening it down every pull. If you notice, once the car goes WOT, the front tires almost come off the front of the dyno from stretching the rear straps. I honestly, didn't want to insult the people helping me. If it went off the dyno, I would have gotten a nice check from them for damages.

Here are the pics I have on my computer:






Intercooler is a standard A2W setup from ZZP.

You should get a a2a ic for the turbo too, should help a bit and it can sit in front of the other fmhe

I thought about it, but there is literally no room. Most of the space is being taken up by my two transmission coolers and their pusher fans. My next stage of mods is to get more cooling for the motor...3.8" Pulley, Ported Blower, Ported TB, Puller Fans on the FMHE, and maybe some Meth Injection. I'm also going to research how to move the IAT Sensor to the LIM. Apparently some Cobra guys do it.

Love this!

Would there be any gains to be had from a smaller pulley?
