I have a BBK 58mm TB and I wnt to get an airfoil before I go to the dyno on Wed. Will an airfoil fit in the larger TB, or is it made just for stock?

 

i also have a bbk 58 mm tb never seen a air foil for one ive looked at holley,slp and acell

 

so are you saying that holley might make and airfoil for one?

 

Any aftermarket throttle body will have an "airfoil" built in unless it is a stocker rebored to 52mm...

 

First off I don't have a BBK 58 in front of me.

The BBK 58mm TB is cnc machined from aluminum. It is not a bored out stock TB (AFAIK no 58mm is). BBK should have and likely did include an integrated airfoil into their design. There is no need for an airfoil on anything but a stock or TB or stock bored to 52mm TB IMO.

Eddie beat me to it, i'm too slow....

 

If I'm not mistaking, the 58mm TB has it built into it so that it has the same effect as if you bought an AF for it.
