Correction, I have seen 500 h.p. slants. I just didn't know it. But to my credit, the dyno video, didn't seem as lively as some 500 h.p. engines I've seen before.
That dyno test was from a few years ago with the old engine. I was still experimenting at that time. As a guess, it was making close to 450hp but had more boost going into it than the new engine.
Also, the weight on the 11.14 pass was closer to 3,300lbs & not 3,500. I had skinny tires on the car last year and added ballest to get the car to hook. It has been long since removed.
