im doing a 408 stroker motor and a HP Performance stage 3 twin turbo kit that has twin t67 turbos (rated at 1200+rwhp).

i am wondering what this kit is capable of and also was wondering if anyone has had any personal experience with HPP and their twin turbo kits.

i was also wondering if it is possible to make it so that the t56 tranny can be made to handle bursts of over 1000rwhp.

im planning on running around 15 psi for the street and then running like 18-20psi for the track maybe.

any helpful info from you all would be much appreciated as im new to the vette FI area.

im looking for a killer combo with this setup

Check out this thread and others that can quickly be found with the search function.

For Tuners, get in touch with Jason @ Texas Speed or Bob @ EPP (Exotic Performance Plus)

Couple forum members to contact about the HPP kit are Mr. Big and Corvette4ever.

Good luck, lots has been discussed about the performance/quality of their product and their customer relations (HPP's).

Definately keep us posted with pictures of your set up. Sounds like a monster.

We've done it before. We've made 1000+RWHP on a forged 346 with our own custom kit that had twin 67's and all through a 6 speed. We actually drag raced this setup. Give us a call if you like, we can get you pointed in the right direction.

Im also building a 408 Iron Block...................

2003 LQ9 Block 9.4:1 Compression
Patriot Stage 3 Ported Heads (LQ9)
Patriot Gold Springs
ECS Big Blower Cam (Have no idea on specs)
D1SC 3.7 Pulley (8 Rib Set Up)
RPM A4 Transmission

Hoping for around 800+ RWHP

im still debating the heads: cartek stage 4 or 5 heads or ET Performance 255cc or 245cc heads or AFR 225cc heads.

also what would be a good cam for FI. i want something thats quite aggressive. def over .600 lift if possible and like 111 or 112 lsa. like i know with boost you dont want alot of valve overlap, but if the duration is something really close shouldnt it be fine with boost (ex. duration 247/251 lift .656/.660 111 lsa)

How did it run at the track? That must have been amazingly difficult to shift a car with that kind of power.

That was PaulZ's car. I think it ran a 9.8 or so with the 6 speed, but from what I hear it was very tough to get it down the track and he was short shifting first and second. He eventually went to a glide and solid rear and went 8.4's or so. Not bad considering this was few years ago and stock cubes with ls6 heads and intake.

Good luck!!

HPP aka Turbocharged power. GOODLUCK. Unless their customer service has increased DRASTICALLY then prepare for an endless wait and excuses ad infinitum. Tom is almost laughable with his constant excuses.

i was also thinkin about the APS twin turbo kit with upgraded turbos since it seems that is the best TT package around for the vette

Bonnetts02Vette

i would like to be able to stick with the 6spd t56 and be able to get into the 8's with it, but if need be then i will switch to powerglide. trying to stick with it also as a street car

Vince99FRC

Are you serious? How old are you?

A glide street car is really hard to accomplish. I mean they can be driven on the street but as far as a daily driver its pretty much out of the ?. As far as 8's with a six speed its going to take much more power then the APS kit can produce. You'll need a big monster of a motor, and two very large turbos. I think a sub 1.5x sixty would also have to happen....none of which are easy or cheap with a corvette. Might want to start off looking to bust into the 9.9x area with a six speed...

Ok ok, ok, ok, lets take a closer look. I don't even know where to start. Well the beginning is always best. You joined this forum 5-28-08. WELCOME! (loved your introduction to the forum btw) So 6-4 you were planning to buy a boost ready 402 motor. Sounds like a great start. I guess that wasn't appealing cause 3 days later, 6-7-08, you were waiting for Julian to get back to you from Cartek cause you were looking for their Head and Cam package from them. That didn't workout so then 6-20 you went to a Livernois thread for a Head and Cam package. That didn't work out so 2 days later sounded like you made up your mind and decided to buy a KB from Jeff. NOW, from looking at all these 500-600 rwhp Head and Cam combos to a 800-900 rwhp KB combo(pending ofcourse you were going with a built block) to now looking at a 1200 rwhp TT set up and looking to run 8s. I'm still trying to figure it all out.

MPRTKLR

8's with the 6sp shouldn't a problem at all. I'm going for 7's myself

highpockets

I would second this WHOLE post ! Its gonna take a WHOLE lot of motor,Luck and cubic yards of money to go 8s with a six speed. Good luck.
