Yep, right at 30 hp improvement from the porting that Wilson did on the intake. This was a back to back test with everything else staying the same. All the gain is from 5500 rpm up so you wouldn't notice it on a street car but a drag car that leaves at a high rpm would notice it.
Awesome!
Don't know if you saw the results or not but my 505 picked up a tenth and 1mph using a Holly Street Dominator that was ported by Streetwize vs. A stock one. In my estimation it was 12-13HP? Sound correct? Motor is all done by ~6300 rpm.
As an interesting aside, I also tried back to back runs with K&N vs. no air cleaner at all and the car ran identical 11.41 times.
