Do some reseach is right...we tuned my friends KB 03 GT to 475/505 on 93 oct. It's all in the tune my friend. I also made 600+ with just a 2.4 KB and fuel system. Your engine will choke the blower, NOT the other way around.

Centrifugal will limit his power curve far more than a KB ever would. Why do you think you don't see many centrifugals on mod motors any more. ESPECIALLY on a street car; a centrifugal will make peaky HP vs flat TQ across the rpm band with a TS.

 

^ that + 1 x SO THERE!! =

 

haha thanks guys, plus id love to have that wine cant beat that, what would be safe boost for my all stock internals? 10 12psi?

 

What ever boost level takes you to about 475-480 rwhp. I know guys that push it and cruise around at 550, but the powdered connecting rods (same with the block) really are on borrowed time at that power level, especially if you whack on it often. Keep it under 500 rwhp and you can beat on it ALL DAY LONG!. It' should be around 15 psi give or take to get you there...I HIGHLY recommend an intercooled kit for any DD. Also get a good harmonic balancer...your engine will thank you.

 

i was at 481 @ 14lbs, so somewhere around there.... (i know i know.... different cars, but just an idea)

 

yea if i do anything with boost i will do an intercooler, but almost 500wheel hp would be sooo sick, i "whack" on my car a little bit soo ill stay around like 12 psi just to be safe

 

i hope you use protection.

 

lmao but yea how do u like ur kb so far mad?? i followed all your threads with the install and dyno videos and what not
