That is a fairly misunderstood comment. The issue is this engine benefits from high octane fuel at high RPM by a fair amount. The power falls off due to fuel stability. With the BPB the falloff is not just fuel stability but now due to a runner length effect. So you still get a good 4-10% power gain at nearly every RPM with E85, you just don't see on the plot a massive WHP gap at redline. The car in this dyno is part of a project I am working on that I will be posting on soon. I have been doing a number of dynos and have been collecting aftermarket parts for an NA project, stick around for dynos of that over the next few weeks. The next parts of the build will include header, op, fp, then intake, BPB removal for comparison comparison, likely an exhaust, and then comparison of 91 vs E85 and possibly ~95 octane fuel (for track days). The last dyno showed the car @ 27%WHP gain @ peak (but with a big falloff at redline). This was on 91 octane.
