How much horsepower will I gain if I buy a BBK 52mm throttle body with the mods in my sig. Also, I hear with this TB makes your camaro sounds identical to a superchargered camaro, is this true?

 

Haven't heard anything about making it sound like an sc'd camaro...as for power you may pickup 5 rwhp...I don't think you'll pickup a lot honestly...I could be wrong though.

 

Little too nothing!! The money could be spent, more wisely
somewhere else. Your car looks great already, spend it on a
suspension mod.

 

I just put a BBK 58mm TB on mine, but then again, I have heads and cam.. Although I don't see how it can hurt stock. I would just get a 58mm.. Later on you are going to want to go from 52 to 58.

BTW you have to have the intake ported to take advantage of the 58mm.

 

Yup...the BBK will make you sound S/C'd at idle.

 

I am also running a 58mm BBK TB and I havent noticed that mine sounds s/c... but I did notice an increase in power especially when I ported out the MAF...

 

I have a 58mm Holly. I dynoed 10 peak hp less vs. stock 48mm. Through the rpms tho I only lost no more then 5-6hp so nothing noticable. you'll have a better throttle reasponse with either TB's 52 or 58. I belive that with my rr's ill actually see some gains from the TB but who knows.

 

If I remember right www.projecttransam.com has dyno sheets of hp/tq improvements on every mod they did to the car....might want to check that as well.
