    Just another gimmick similar to the 'Tornado' insert that they try and sell stating great HP gains

    Isn't the airfoil only for LT1 cars?

    According to the link below, it does work. Is it worth it? Probably not. Peak gain was about 2HP and 2 lb-ft. Average gain on the dyno was 5.1HP and 1.9 lb-ft. Unless you're a die hard racer and need every 1/100 second, I don't think you should spend your money on it.

    The original poster shows they have a 01 TA, so if it's for that car there isn't one out. The dyno shows it is on a 1996 LT1 TA and airfoils have been proven to pick up a couple h.p on those. There are throttle body spacers and vararam makes a insert to fit into the Throttle body. I seen people complain of lost TQ with the spacers and the vararam insert I did buy and it melted 2 weeks later, started to bubble and even before the heat warped it and made it bubble I seen zero gain. I ported my own TB and did see a little difference in feel and times, but only about a 1/10th. That gain could have been due to getting the angle of the butterfly on the TB perfect, more than the porting itself.
