Hey Garm,

I was just thinking of engine longevity from not sucking abrasive dirt particles into it.

The full 180 degrees of the velocity stack profile actually extends well into the air filter because it attaches to bottom edge of the skirt...



...and those 6 inch filters are massive.

This is what I was referencing in a previous response. My buddy's SR20 set up has:



With the rpm's produced along with speeds he pretty much has not seen any issues inside his engine from running with a "direct" porting through the driver's side headlamp assembly. Sure, there could be a possibility, but when you are racing you are always aware of what is going on and used to taking calculated risks.

Competition is a totally different mindset where winning races outweighs making an engine last 100,000 miles.

Running like that would creep me out. What happens if another racer's tire kicks up even a small rock and it gets sucked into the turbine impeller and into the engine?
