HELLO!!!! Q, What kind of gains in HP will i se with Headers + ported plenum with TPIS runners + Afpr and what 0-402 times will i see. For now the car is stock exept for kn filter and chip.
The car is a GTA-90 350 with 3.23 THANKS!!

 

My my aren't we energetic

you might see another 30-40hp with those mods and a nice tune

 

WoW!! thats more than i hoped for. Are runners worth the money ore should i do something else?

 

They are if your car needs them...


However the bigger restriction is in the base.


Maybe if you highly ported your stock base, then the runners would be a good buy.

 

Headers, AFPR, Edelbrock Base, and a Cam would be better!!!! Get good deals on the stuff! I got my SLP TRI Y stainless headers for $300 with shipping, AFPR for $50 with shipping, ZZ4 cam and brand new maching shop ported S/R torquer heads for $450 and thats with shipping (one of the best deals ive ever seen on thirdgen.org) I just bought my edelbrock base for $285 and thats with shipping also..... so look around and be patient and youll save tons!!!!! OH YEA I JUST BOUGHT ROH ZS 17x9.5 wheels with 275 Eagle GSC's in really good shape for $625!!!!!!!!!!!!!!!!!!!!!!!!! LOL i love to wheel and deal

 

What will new TPIS runners cost me? Someone told me that i will se gains off about 20hp, isn´t that
