700 Horsepower Hayabusa

By Paul Crowe

Getting huge horsepower from a motorcycle engine is always an interesting blend of good old engine building, forced induction and a little black magic. The DynoJet Horsepower Challenge has just produced some totally insane results. Hank Booth of Great Falls, Montana put his 1999 Suzuki Hayabusa on the dyno and turned out 701.32 horsepower! There were others in the 400 and 500hp range and usually, that would be a winning number. I guess Hank had other ideas.

Other winners in the Import Unlimited class with Booth included; RCC Turbo/Richard Peppler, of Ontario with 559.02 HP, and Glen Bertagnoli coming in third with a 445.16. Both competitors were also using the dominating Hayabusa powerplant as the framework for bikes.

Revving the scale in other classes were, Kent Stotz with 210.76 on the HRCA, Velocity turbo powered Honda in the Import V-Twin Cruiser Open class. Super Street Bike Magazine/ Don Smith squeezed a respectable 118.28HP out of the diminutive in comparison 600cc Suzuki.

The domestic bikes were represented by those from Harley Davidson. Kevin Kelly, Weston, FL brought in 247.67 in the V-twin Unlimited category followed immediately behind with Nick Trask, Phoenix, AZ generating 228.0HP. Brandon Rybicki brought his turbo-powered Harley V-Rod in at 191.74 with Harry Gunnusen directly behind him at 138.68 and Gary Salisbury led the older 89-95, Twin Cam class with 135.81

These are my kinda numbers!
