Yeah the Engine Master guys were having to heavily rework heads a few years back to make numbers like this and now we can hit the number with OOTB heads. Pretty cool that technology has moved forward that much in the last few years.

The 15 hp is peak to peak. The std port intake has a big hole in the torque curve which I assume is due to the mis-match. The Wilson ported Indy has a much better curve. I need to pull up the old data and look at it but this Indy intake right out of the box was a bit of a mess on the dyno. So the Wilson porting is what saved that intake.
