Pauls engine (or now Bob's), made 190ish rwhp and 130ish ft lbs of torque last I knew. BUT, it was pushing the limits on the supercharger and was (supposed to be) using alcohol injection to cool the charge when under full boost.
On a stock engine the system is not very efficient and creates a lot of heat (which kills hp). I've actually run against stock engines with the superchargers and wasn't all that impressed (other then the look and sound). Even at the Thompson drags I was actually running about a half second faster with a stock bike with Kerker and one of our jet kits (a lot of that is rider but I think his MPH wasn't much better anyway).
The bike in the video is most assuredly faster then most gen 2's.
I do have a 1500 longrod engine that I am either going to use or sell (wouldn't mind selling and we will build a stroker motor to replace it). It was making 200 on engine and 300 on the nitrous. It was running 8.30's at 160rwhp.
