So I just cut my 90 degree elbow that was in the fender off so it's a straight shot into the intake. The pipe that goes into the fender is only 3.25" or 83mm so it's definitely still too small, I ordered a 101mm maf adaptor for my air filter to attach to in the fender. With the 3.25" pipe on it, I am now pegging my lightning maf...
a 3.25" tube will provide more than enough air for this engine.

I thought with my heads breathing the way they do, the higher intake duration would help. My mistake I suppose. Thanks for the reply NA svt. What sct mad do you recommend since I'm pegging my lightning maf?

the intake centerline is far too advanced from where it needs to be to make any power at 7400rpm and is the reason for it peaking so low. For example, I have a bb/s peaking at 7500 with only 233 deg intake lobes.

I would degree the intakes to 112 and the exhaust to 114.

Who came up with the 107ILC?

I think his name was Mark at bullet racing cams.

Larger headers will add a lot of average power above 5000rpm. Peak gain could be 20-25 at peak.

BBK headers are shit.

My guess is that moving the cams and adding larger headers will add 50hp at 7000. The larger headers will help a lot due to the short exh duration.
