Would it hurt to run one on a stock car? I mean I am spraying it, but the reason I ask is that I found one cheap on Ebay and was thinking about getting it. Thanks!

 

i dont believe it will hurt and i am pretty sure it wont help

 

it wont help but is worth buying at a steal if u think u might need it down the road....like if u are planning on building a 383+ci motor with heads and cam then go for it...somepeople re program the ecu once a bigger throttle body but not sure if u actually need to

 

If you have an auto, you may need to get the pcm re-programmed. I never looked too far into it, but there are some pcm tables that rely on TPS% to set the line pressure. Any of the mail order guys should be able to do it.

Also you are going to loose some fidelity in your gas pedal -- for the same gas pedal input you are now going to get a bigger opening in the TB.

 

if your car is an auto than you will have to have the pcm tuned otherwise the shift points will be messed up since it does rely partially on throttle position in part-throttle shift points

 

Spend your money elsewhere.

 

kinda on the same page i was wondering what kind of increase would somebody get if they installed a ported intake (58mm tb opening + ported runners) and a 58mm tb??? I planned on throwing all these things on when I get my heads and cam, but Im getting kind of tired of waiting.... Would I see any gains?

 

"97formulakid " I see you have a m6. mine is an auto. I just installed a 58 nos tb by holley. A kick off dead idol has a small blip or bog. very small. Im idoling at @800 by stock tack.
