Yep, as you can see on ws6.com they gained an average of over 5 HP under the curve with just the addition of the airfoil. I have seen even more especially with headers and full exhaust already done.
It really shines with a built larger cube motor, and of course a power adder.
Most aftermarket TB's have a type of "airfoil" machined into the body of the TB.
Would buying a 52 mm throttle body do any good, because i just have a stock one w/ an airfoil on it. Seemed to idle smoother, other than that i noticed no difference.
Fred could probably give you a more concise answer on a larger throttle body, but suffice to say, unless you're going to be putting out well above 500HP, it's not needed.
