Ok so I took my car for the longest drive sense I've had the turbo (on3) on the car! I went to make a hard pull an when it starts make boost it starts falling on its face like the is no timming in the motor! Sounds like its making power but its just not pulling hard! Got home and it sat for about 30 min or so and I opened the hood and started looking at things! Grabbed the cold side pipe where it goes into the TB and it was pretty hot! Almost hot enough that it kinda burned if I held my hand on it too long!

It's this consided heat soak?!? If so what's the cause/fix?

after sitting for 30 minutes the engine heat escaping the bay will get the pipe hot like that. or sitting at idle for awhile, but when the car is driving it gets cooler

I dunno what the temps are in South Carolina but here in Texas, heat soak IS a major issue. After converting from supercharger to turbocharger it was even worse! So it is very possible your intake temps wetre getting too high and timing was being pulled.

It's cooled down significantly here and now my car feels like a rocketship the entire trip.

I'm thinking I should wrap the down pipe and maybe the headers and even try a spacer between the upper and lower intake. Wouk weaping the cold side pipe where it's close and crosses over the down pipe help too? Any other suggestions?

Definitely wrap the down pipe and crossover. On3 doesn't warranty the pipes if you wrap the headers.

What was the outside ambient temp?....How much boost was it cranked up to when it was falling on its face? My car will fall on its face at the track if the outside temp is over 85 and my boost is over 15psi no matter what timing I have in it.....Intake air temps just plane get too high. Methanol will most likely take car of it but I dont have my car tuned yet for it or e85. Too much timing, high boost and heat makes turdblower cars run like crap....Thats why all the drag racers run air to water inner coolers and e85 or methanol. I can almost assure you that your intake air temps was too high..

Ambient temp was in the mid to high 70s. Only making ard 5-6lbs of boost right now. And I've been reading up on meth injection! Seems like the way to go...

Well the cold side tube coming from the turbo to the intercooler is only 1/4 away from the cross over exhaust pipe and the the cold side pipe going into the throttle body is almost touching the down pipe. On3 design.... Not to mention the day I had that problem I was going down the hwy turning 2800 or so for like 1 1/2 hours. Wrong gear for the turbo I know, haven't got around to a new gear set yet!
