The video was cool, but the constant claims of 335 HP are a bit much.
If I remember correctly, when I read Joe's book, all his "engine combinations" and HP claims were based on a "software dyno" - not true empirical testing on an actual engine dyno that was known to be accurate.
With that said, he seems to be a good dude, and his products and books have helped a lot of people.
Would have been nice to hear it run.
