Just thought I'd let people know, the TPiS airfoil (59.99 Jegs/Summit) is well worth the money! I thought I had nice accelleration before, but this made it noticably better!

 

It's nice to know someone had a good experience with it. I noticed jack when I had it. I ended up returning it.

 

i didn't feel it pull any harder but i did notice a nice trottle responce.

 

just a better throttle response.

 

Whether or not you notice it, it's there.
Flowbench tests have shown real CFM gains... just a teensy jump. Those are important tho too IMO. The little things that is.

The airfoil is said to allow about 10-15 more cfm thru the stock 48mm TB.

 

i have a airfoil, cheap mod, took the one from my 88 formula and put it on my 91.. easy install..

 

you paid too much, SLP sells them for like 30 bucks www.slponline.com those things are always on sale.

 

Ok, maybe not worth $60, but when you buy a used throttle body off ebay for $30 and it comes with the airfoil and the TPiS brushed aluminum top cover, then it is worth it!

 

60 bucks? Damn. I have an SLP airfoil mold and like three air foils in my garage, I wish I could get a quarter of that for them ;p

 

I'll buy one from you. PM me.
