    What size depends on what you have done or what you are planning on doing. 52mm is a basic bolt-on for most guys. But if you are running FI, nitrous, or a big H/C, then you may want to look into a 58mm. But if you get a 58mm, you'll need to port the manifold to accomodate the larger openings.

    And post some pics of your show car.

    What kind of mods do you have already?? TB's are worth little to nothing on mildly modded cars.

    With your mods a 58mm throttle body will be worth it. Porting the intake by itself is worth a little, Advanced Induction has three stages of intake manifolds that work really good. But ofcourse you'll always get more if you port the heads as well!

    Technically, with the exception of the 100 shot, he's only running bolt-ons. Between the 52mm vs 58mm, you won't see much of a difference right now. If you plan on more modding, then you might want to consider the 58, but if you are satisfied with the bolt-ons right now, I think the 52 would work fine.

    Word of advice hypertech and nos don't mix to well with the programer will lean the out the motor which can cause damage.

    From my experience if your going to do a throttle body, 58mm (or AS&M 54) is the only way to go if you have a chance on making any power at all. 52's are virtually worthless.

    I've seen a 52 support more than 500hp.

    Stock tb isnt the restriction point on a bolt on car. Not even that much on a heads/cam car. They're pretty worthless mods. Less than 5hp in most of those applications. I wouldnt bother.

    Yeah for the money they're not worth it at all for a bolt-on car. I just spent $512 for an Air Speed & Marine 54mm for my vette and really don't even know if it was worth it since everything wen't on at once. I figured with the cam and LT's it might have added a few.
