I would nto go over 1.5 bar on good gas and maybe EBC to control the TQ... ( keep it low).
Im guessing half of the members keep the blown motors quiet and just fix them. Not something to brag about. you can run hard at 800rwhp 20 times but the 21s time it can go...
so be smart...

Mark what alpha turbo is safer for our stock motor??

 

Alpha 3076 on stock motor
GT3076R's with forged internals

 

868rwhp on a stock motor the motor came out working 100% (dynoed month prior and made 840rwhp in the Summer heat). We decided to do the motor build when I fragged 3rd gear.

For the 8XXrwhp setup I ran around 3k of the 6k miles on race gas (so 8XXrwhp at anytime). During that time (9months to a year) I set every stock motor record for the 996TT platform, except the standing mile. Previous to that I made 666-700rwhp on a GT3076/K24 Hybrid Setup for a decent amount of time.

Downfall... Motor had 4 rods you could see and not have to guess that were bent. The car was 100% working order and had dynoed a month prior. I've heard from others that a few builders have seen the same while the cars continue to make big power.

Big HP setups on a stock motor is keep the torque low. Boost level doesn't matter. 1.5bar on GT35s and 1.5bar on K24's is a LOT different ballgame. Cylinder pressure is what blows stuff up and is not not 100% relative to a set amount of boost (it's HP basically that creates cylinder pressure). Would I recommend anyone to do what I did? No... I have a lot of experience with high HP cars and understood the risk of everything going into it. One small mistake could have been VERY expensive.

 

What do you think about A3071??

 

I've had them for few years and its more than enough power for what I need, if I ever get caught I won't get a ticket - I'll be going to jail That said I don't believe in road racing, to dangerous for other innocent drivers, take it to the track were it belongs.
