hoping for some usefull input on this one..

 

your question doesnt make any sense

 

agreed. what makes this horsepower you want to acheive?

 

9200rpm. I've been running that forever on stock itr valvetrain and itr cams or toda spec A cams.

 

I would think that its not HP that has a limit but the RPM that the valvetrain can handle.

 

ok.. can it handle 400+ whp??

 

HOW ARE YOU MAKING THE DAMN HORSEPOWER?!?!?! BOOST. IF SO, HOW MUCH BOOST. JESUS CHRIST.

 

well.. boost of course. i have not idea how much boost its gonna take cause i haven't even started on that part yet. i tried making this question as simple as possible. my basic concern is about springs/retainers/valves unless theres something else to worry about i can't really think of

 

for 400hp or anything over 10lbs, i would reccomend springs and retainers. Its just one of those things that is extremely safe to do. and the last thing you need is a valve dropping because of valve float

 

thanks for your input..

so you know

not all turbos are same size.. some may only make 240whp at 10psi.. even if its same turbo, depending on piping or other variables you could give take 10-20-30 or more hp.

 

i know. thats why i said 400hp or 10lbs.
