I heard from an engineer that many modern engines now use a mechanism (fins or spiral grooves of some sort) near the throttle body to even disperse the air charge.

Anyone know if FS engines have any mechanism to spin the air charge to aid in combustion efficiency?

I'm asking because I'm looking into throttle body spacers that induces this type of motion in the air charge. NO I'm not talking about the Turbonator, SpiralMax, nor the Tornado.

 

It's the "mesh insert" thingy I believe you're reffering to. Check out the thread here for more details.

 

I checked out the thread. Quite interesting and worth experimenting, although it's not what I meant. Thanks for giving me something to do this weekend tho!

BTW, Throttle Body Spacers are also referred to as Air Intake Runners I think....
