From what i have seen, the air foil really isn't worth the money. That money could be put into a new larger diameter throttle body that will not need an air foil.
Quote:
? 15-20 hp on a stock motor
? 50-100hp w/ cam and mild head work - i.e. valves & hand port
? 100hp+ on hot 383ci and larger motors
You will not get these kind of gains from just a throttle body. IMO there are more important mods to do such as intake, exhaust, gears, stall, etc. If you are looking for a throttle body, you can have yours ported out to a larger diameter, or you can spend some more for a brand name tb. You can get a holley 52 for a very reasonable price from some of the sponsers.

I have a Air Foil in my 97, and I could feel the difference. I mean I didn't even know it was there until a buddy and I took it all apart to look at my TB, and found it all cocked in my ducking. I was pissed. The one you are going to buy is better than mine, because of the set screw. I would go for it.

an increase of 30 CFM, at WOT, running 5+ grand RPM. That's equivalent to 2 HP peak. Unless the total cost is 2 dollars, it's not worth it, in my opinion.
