Stillen CAI and Invidia CBE

Dsphoto · 10-07-2010, 06:19 AM

I opted for the G2 CAI so the bumper wasn't off. I elected to go for the reduced maintenance hassles. I think that the total gain is more evenly divided between the two bolt ons than the dyno results indicate. The improved pumping efficiency resultant from back pressure reductions on both sides allowed the engine to breath. Had I installed the CAI first and the CBE second the results would have been the opposite. Stillen's dynos results show only 1.5hp increase in max hp and 9 hp in midrange, far below my total numbers.
Most important for everyone to see is that by improving pumping efficiency on only one side of the motor does not allow this wonderful engine to really sing. You need to improve both intake and exhaust to realize major gains.

To clarify you have the Stillen Gen 3 CAI and not the Gen 2 right? I would think the Gen 2 are easy to maintain than the Gen 3.

Why is that ?

The gen 3 mounts the air filters behind the bumper while the gen2 mounts inside the engine compartment. No need to remove the front bump to clean the filters.
