I'm looking for the best (and cost efficient if possible) way to increase air intake velocity at the throttle body of a late model LS V8 engine.

I see there are companies that have specially designed throttle bodies (like the JET Powr-Flo Throttle Body) that have dyno proof that their throttle body increases air velocity... If anyone know of companies other than Jet to look at for this, please let me know.

Another option I've seen is throttle body spacers which should do the same thing to increase incoming air velocity even though they sit behind the throttle body.

Anybody have any recommendations for a good spacer that increases velocity?

Just wanted to get some recommendations from those that have done what I'm looking to do... increase incoming air velocity - Thanks!

 

And, the folks at Jet claim their JET Powr-Flo Mass Air Sensor provides "airlow increases of up to 45%".... can a mass air sensor do this?

If so, are there any other options other than Jet to consider?

 

Both are bogus. Tell us more about your build and we can point you in the right direction.

 

<p>Stay away from those mods until you require them. &nbsp;Right now neither is your largest restriction.</p>

 

best way to increase velocity? forced induction of course.

 

Run a smaller throttle body. That ought to increase air velocity at the throttle. Why someone would want to do that though...I don't know.

 

Air velocity only applies to carburetor or TBI setups. You're fuel injection, not to mention your intake runners (inside the intake behind the throttle body) are what control velocity anyways.

Looking to up velocity is not the answer. Looking to reduce restriction of air to the intake runners is the answer.

Or go boosted, then both velocity and restriction are largely moot points.

The stock intake system is good to around 350RWHP before it becomes a real restriction on power (just keep it in mind). If you wanted to go better, you would need a true cold air intake setup that draws air from under the bumper, not the engine compartment (the stock system pulls cold air from the inside of the fender, just not high volume).
