I just purchased a throttle body air foil from ebay! I am I going to notice a difference in hp??

 

Not really. GM HiTech just did a dyno test and saw a few HP. I have one. Cant hurt.

 

Agreed. You will not notice any performance gain.

Maybe 3 to 5 HP.......again, not enough to notice.

please make sure u secure the screw/s so it does not back out.

A member on corvette forum had one spit out its screw and it went in to join a piston for a lil while... it was like metal hamburger in there.

Oh thanks everybody! I tighten it down good but I think I will be rechecking it before I start driving it again. Thanks popo8!!

 

My pleasure man. Id hate to see anything bad happen.

Well I re tighten it really good. I think I stripped it. It shouldn't back out now.

 

lol what?

 

Well, I hope you DIDN'T strip it......because if you did, it won't hold at all.......

Yeah...if you stripped it, then best to remove it and get another one. You also need to make sure that shavings from the threads don't get into the engine(if possible). That may involve taking off the throttle body and removing the airfoil on a workbench. Then you can turn the throttle body upside down to make sure any metal gets removed from it.

Next time, use some blue thread locker on the threads and snug it up tight(no He-Man like force needed).

 

At this point it's probably a good idea to remove it, throw it away, and never buy a new one again.

 

im hoping he mean he stripped the end of the screw....

No just the head. I can't get it to back out. I over tighten it. I wanted to put some thread lock on it. I'm such a amateur!
