throttle body question.
throttle body question. Ok, i have a basically stock 97 Z28. It has a Loudmouth II exhaust and an offbrand CAI. I am looking at getting a throttle body air foil for my stock throttle body. I can get one for about $20. Would I get a noticeable horsepower gain OR should I spend more and go with a 52mm throttle body. If i would go with the 52, would i notice more power with the setup i have or would i have to add a bunch of stuff to make it noticeable?
You wont notice the power difference in a 52mm TB. Nor will you notice the difference in an air foil. But if you plan on upgrading latter on I would go with the TB. over all you get more power out of a 52mm tb

As for the first post why dont you not buy either and spend the money on something more useful such as a stall/clutch, headers, gears, etc. Your really not going to feel anything from either one of those mods. The airfoil will help your TB flow like 40 more cfm, so it is worth maybe 1 or 2 hp. For 20 bucks id probably ****** it, but dont buy the TB. get something useful instead

I would have your present TB ported.
I believe the stock is 48MM, I had mine ported another 4MM.
Its just not worth more than $100 IMO.
Dont worry about your TB right now, get other things. Gears/Stall ( if auto ), Headers, are better choices.
If youre going to mess with your TB, you might as well re-do the valvetrain @ the same time if you want to maximize HP.
Say a nicer cam, 1.6 RR's and Roller Lifters.
