Hey guys, I wanted to provide a little dyno comparison information. This unfortunately was not generated on a roller dyno, but using the virtual dyno. Which I have used for many years now and compared to real dynos and when I say this is a very accurate comparison, I mean it. Take this information as you would like. Don't let the numbers blow you away or skew the results.
This is comparing my 2015 GT 5.0 Base model Performance pack with Steeda CAI, Stainless Power Catless 1 7/8" long tubes, 2.5" x pipe catback exhaust. I am running lots of igntion advance, more than most email tunes will provide on an e85 blend. I can definitely see why I ran out of fuel tuning e60 and had to dilute to e40. The first pull is with the stock intake manifold with tuned VCT optimized for my setup with the stock manifold on E46, the second pull is with the Boss manifold installed and with E40 on the same stock intake manifold tuned VCT, the third pull is with the Boss manifold on E40 with my new tuned VCT for the Boss manifold. After tuning the Boss manifold VCT I can no longer run over E40 otherwise the injectors hit their max. Now I must upgrade. Max flow seen on the stock intake manifold was 45.8 lb/ min at 6600rpm. With the Boss manifold and VCT optimized max flow is at 52.1 lb/min at 7800rpm.
I'd like to point out how well the stock manifold performs below 6000 with the torque it maintains, but man, after VCT was optimized the torque picked up in a few spots with the boss as well as the top end. With the way I have the car tuned now, driving around town feels better with the Boss because I am running more advance on the cams and actually making more power at partial throttle over the stock manifold with the IMRCs closed and the VCT that they run. Now, that doesn't mean the stock manifold cannot be optimized more at partial throttle and feel even better, its just the way I have optimized my current setup with the Boss. I have noticed a slight drop in fuel economy as well, but who cares. I have the rev limit set at 8000 and it loves staying in that power band from 6000-8000rpm. I am working on fine tuning from 7500-8000 to fix the drop off in power, but this might be the nature of the manifold and my setup.
