crash

Pretty much what it says. What effect does it have on spool-up, Exhaust flow, etc. I was thinking of making my own Kit since PTK would want me to bring the car to them. I have the ability, and some knowledge, I just need to finish what I need. The motor is going to be a 383 with a PT-96 Turbo. The question is 1. can 1 3/4 support 1600 crank HP? 2. will going to 1 7/8 hurt spool-up that much that I won't be able to use it all in the power band?? 3. And what other bad side effects would come from upping the primary size, aside from the delayed spool??

I guess this is for you hard core Turbo guys...

1 5/8 or 1 3/4 will support 1600 without issue. 2.5" crossover.

my guess is that with a T96 this wont really be a street car.
if it was me id use the 1-5/8 that should be plenty big

The car will without a doubt see mostly track time. I was going to use a straight PTK Kit since it really is an LT1, but They don't offer a T-6 flange for the turbo. That and it's kinda big... But yeah it'll be mostly track And I'm thinking I may end up using the 1 3/4 like the PTK kit, just route it in my own way. Surprisingly though the car will see a decent amount of street miles...Nothing Like the Power Tour though. But it'll be around locally. So now the kicker is finding what primary length to go with as well. URGH, the joys of building High HP motors...

Oh, and I plan on getting it to spin to 8K. Don't ask me how yet, but I will...Figure the motor will be screaming to launch something though!

Thanks For the responces so far guys.
