Just wanted to add a little (ok, a book) to this one. I've had 4 Boss Hoss bikes and two trikes. All bigblocks (GM ZZ502) with the exception of my wife's '63 Vette trike which was a ZZ4 (350 smallblock). Currently have a highly modified V8Chopper (see v8choppers.com) and an '05 'Busa, '05 BMW.
First, Boss Hoss is NOT a Harley. It is a privately owned company out of Dyersberg, Tenn. Largest mfg of V8 bikes and trikes with a current production of appx. 250 units p/yr.
Are you from Minnesota? The guys who are running up there mostly bought from Marv Jorgensen from Chopper City Sports in Fridley. Marv has some very badass 800+ hp bikes and is one of the few that are really accomplished riders. Marv,like me, is an old guy and has a few world records including snowmobiles. He sells a lot of nitrous sleds. Very cool guy. Most of the guys he does Boss Hoss modifications for end up with an 18" rear wheel and big car tire vs the OEM wheel which is 15" with a 230 Avon. I had tried one of Marv's rear wheels with a 285 Sumitomo (Viper tire) and it sucks beyond belief for anything other than straightline. My buds would give me a real wide berth on those interstate cloverleafs you refer to, hee hee. The guy was actually able to get up to 15 mph?!
I had posted on another thread much of this info including a run between a ZX12R and a bigblock Boss Hoss. It was the BH factory guys and the results were embarrassing. Not a good race from any speed. The 12R kicked it's ass. It was deserved as the head honcho at Boss Hoss was extolling the Boss as the fastest production bike on earth. "Buulllllshiiittt".
99% of the guys riding Bosses with NOS bottles are all show and no go. I've met a bunch that are skeeered $hitless of getting into the secondaries no less hitting it with a 150 horse nitrous shot. No, the guy you came across was probably on a stock setup, short of nads, and not giving it a squirt or it would have been close.
We run Bosses and V8Choppers at the track here in SW Florida a few Fridays of each month. Some of us (like yours truly) also have other bikes like 'Busas. Here is the for real skinny...
Any STOCK Boss Hoss, whether bigblock or smallblock, cannot touch a ZX12R, ZX11, GSXR1000, or certainly not a 'Busa. Even the modified motors such as a stroker (383) smallblock or stroker bigblock (540), won't come close from a roll. From a launch, it's a joke. Wheel spin, especially on the bigblock puts up a bunch of smoke but no linear acceleration. My FJR1300, with the saddlebags still on and brand new, beat a stock smallblock Boss repeatedly at the track. We video'd just to ice down some of the Boss owners that thought their bikes were the fastest thing on the planet. Here's the real numbers guys....a stock smallblock Boss, 1/8th mile = low to mid 7's. A bigblock isn't much faster and only occasionally will get into the very high 6's. I've seen stock 'Busas at the same track doing mid 6's consistently. These are with accomplished riders. I've seen bigblock Boss bikes running mid 8's due to poor hook-up. No shifting as we go through the 1/8th in first. No gearing issues as there are only 2 sprockets and only 2 teeth different.
We have convincingly beat R1's, 'Busa's, and others when spraying a "good" Boss and from a roll. When I say "good", that doesn't resemble factory jobs. We throw out the Edelbrock carb, change the fuel pump, change the ignition, and adding at very least a Sniper nitrous setup with a minimum of 125 hp.
Just thought I'd set the record straight as I've had 4 years of experience with the V8 bikes and a number of other bikes. No wonder I have a 'Busa in the garage eh?! Best,
Elliot
