To those with the JL Ram Air set up, What kind of ET reduction are you seeing from the JL Ram Air set up with the Power Stack filter over the factory air box?

Thanks,

HANKFAN

 

In back-to-back testing, I got .08 to .10 difference in ETs with the filter vs the stock air box.

I did not do back-to-back tests on the ram air, so it is harder to say what difference it made. My guess is about .05 for the ram-air.

YMMV.

I know mine was sucking in some cool air when I ran my time below at Cecil County also. Not to mention, the great barometric pressure we get there Weather has alot to do with our times....
