hello all....we all now you can gain some horsepower by adding a cold air intake quality header and a good flowing exhaust system. with that said im wandering about the "air raid" throttle body spacer in the summit book. is it really worth the money? im thinking about doing a little bolt on build ( i dont want nothing crazy on the horsepower at the moment) so im thinking a S2 TB P/P a f22a1 head and IM re-rout the cooling lines on the IM and a insulating IM and TB gasket a pacesetter header and 2.5in pipe out the back no cat...gotta love florida. so im wandering if that would be a good 50-75 whp gain?

 

you'd be lucky to get half of that.

 

kinda figured that do you know anything about the throttle body spacer?

 

Hell be lucky to even get a fifth of that lol..
It does nothing. How exactly do you figure it will increase HP?


Good luck with your bolt ons OP. Youll quickly realize that all they do is make your car noisy and youll gain very little power.

 

reason for only bolt ons at this time is because later on it will be getting 89mm bore with some 11.5:1 comp bisi pistons so all the little "bolt ons" execpt the throttle body spacer will stay
