So it looks like there may be some silver lining with the Racer X intake for my purposes. The TT class I am competing in this year has a standard HP/weight ratio. I am too high on power to be competitive with the e85 on stock intake at 195 without a ton of aero and sticky r7/a7 tires. I'm not ready to commit to a full race car yet, so I need to be around 185 to be in an ideal spot.
Yesterday I went back to the dyno to run 91 octane on the stock intake which would put close where I need to be. I ended up around 180hp with some slight potential to lean out further and possibly gain a little more power. This is a good safe spot to be for my class, but I decided to have an overlay of the RacerX with e85 vs the stock intake on 91. I'm glad I did, as there is a lot to be gained under the curve and still keep my max HP within class range.
Below you can see there are considerable gains in areas that will be very beneficial for my classing. I know it's not a fair comparison for most scenarios, but it's perfect for my purposes. I may go back after re-installing the RacerX to dyno test on 91. Best to not hold your breath on that, as it will be a while before I'm able to.
