HP? I would only be guessing but I would GUESS that these guys are in the 800-900 neighborhood... UNless it has Paul Grichar power, then it is MUCHO higher...Kidding about that, kinda... GN7 BOB would be a better one to ask but I do know they run pretty high PSI manifold pressure for what they do...
The GN class is my absolute favorite of all the classes, when you know a little about building engines and then see what kind of torture these guys endure in the LONG runs, with such a heavy hull, in comparison to a K or an SS hull... These guys could break an ANVIL in these boats, its some serious torture and GN7 had the whole engine combo figured out... Going fast is cool BUT finishing the FINAL is even cooler, there is MAJOR fallout in this class due to the torture...
The first time I heard the Plan B 305 boat really crack on it I got an erection like a 18 yr old kid...![]()
