I don't have alot of money now and still looking for some small mods but will this special material be better then the aluminum. Will it make the nice whistle noise. I know aluminum material heats up and also with friction faster. Here is the info and picture.

Why would that make a whistle noise? All it does is smooth the air separation as it enters the TB.

 

Not sure if one Air Foil is better than the next, they all look pretty much the same-ish.

 

its the difference between .0003 rwhp and .0004 rwhp in either direction. I would buy the cheapest air foil. it seems like everyone buys one then ends up putting it on a shelf 6 months later when they upgrade the TB.

 

Agreed, it is not a mod that is going to make very little difference, it's not going to matter which vendor you went with.

 

Why in the heck would you want it to whistle?

 

Some people stated that with the air foil or smoothing out the air foil makes it whistle and I would love to have that super charger sound. The girls might get more wet.

 

Poser.

 

I was thinking the same thing. My throttle body kinda whistles and it bugs the crap out of me.

 

You can get the "supercharger sound" with a worn out power steering pump too.
I have one here somewhere you can have, but I don't think anyone is gonna get wet off of it.

Put a baseball card in your rear spokes while you are at it.

 

Gotta love the LT1 crowd.

 

get this and u can sound turbo too

lol

 

Da whistles go WOOOOOOO WOOOOOOOOOOOOOOOOOOOOOO!!!!!!! (Bub rub)

 

Would you even see a difference in an airfoil on a dyno?

 

My K&N whistles in the higher RPMs during throttle let off, that's enough for me....if yours doesn't maybe you should clean it.
