Just a thought...but I posted this up on the other BB board (much inferior I may say)...CAN A STOCK BB BE GEARED TO HIT 200+..????

Yes of course. Will a stock XX make enough HP to over come the resistance to do 200MPH is a better question. I really think it could on a long enough straight away(10 miles or longer) with the right gearing and setup.... They did it in the 60's with bikes making 50HP... |

Sounds like fun, let me know what gearing you come up with.. I've only done 200+ once, and it wasn't my bike, I'd like to own a 200mph bike..

18 frt...45 rear...That'll get you to 200 mph at redline.. The problem is finding the extra horsepower to pull the revs. Hank |

Hank's right... 18/45 and some intake assitance (NOS, turbo, supercharger) will do it with relative ease... at least I think so...  | |

Kent Stotz does it on his Bird in exactly 1/4 mile !!!!! Not sure the gearing tho  |

Not gonna happen!!! We ran Chris's XX which is pumped up, as well as Forrest's turbo bird and the most we saw was 187mph at Hookers and that was with a crazy little 130 pound psyco rider onboard. It was maybe 4000 ft elevation but you would need 200-220+hp at sea level, with a hellova long straight to make it to 200mph! A buddy of mine races a CBR1000RR that puts out 193 RWHP and on Fontanas looooooong front straight he only saw 185 mph. Now thats a good half mile + straight on a race bike with a 90mph run on at the straightaway. Your dreamin dood!!!!

Gots to concur with Randy and Ixxion.... this isn't going to happen on the stock Blackbird with gear changes alone. Mmmmmm...... okay, maybe if the bike was dropped from the Space Shuttle, it could see 200 mph at some point during re-entry....  |

I found a calculator for this type of thing and plugged in a coefficient of drag of 0.65, a frontal square foot area of 6.2 (Busa is around 5.9), and weight of rider and bike at 725 lbs. It says you need 205 HP to go 200 miles per hour. Now this assumes you have the proper gearing. There are also calculators to figure out the proper gearing you need. The bird will go 200 mph, and one of these days, I hope to turbo mine, and gear it for 200 mph plus. |

I dont think so, considering a MGP bike puts out 230-250RWHP, is 200+lbs lighter and less frontal area and they only hit 210-213mph. We have to remember that at 190-195 the wind coeffency is increased dramatically. To push through this barrier takes alot more than 99% of the motorcycles on the road can do.

As Dan said, and I think we all agree, the XX can turn 200. It has the mechanical foundation and aerodynamically capable. All you need is an extra 100 horsepower and the job is done. That's readily attainable with a good turbo system.

Naw, it's not all about horsepower. Getting past the drag and the force of wind against the frontal area and around the airflow is your biggest problem. Mr. Stoltz' bike is significantly different in the height and absolute shape. It's like a NASCAR car, yeah, it looks like a Taurus, but it isn't anything you could concievably get at the dealership.

I was under the impression that in those streetable classes, you weren't allowed to change the shape of the fairings....otherwise they'd just run a full funny fairing. You can slam the front, and lengthen the rear, but if you could alter the profile of the stock fairings, why do so many guys agonize over trying to fit their intercoolers into the stock fairing setup when they could just enlarge it?

FWIW, there is a whole lot more to aerodynamics than the shape of the front fairing. In fact, the rear of the bike is probably equally important. Take a closer look at Kent's bike. The rear of the tank is sloped to allow him to tuck in better. The rear bodywork is much longer than stock and, I'll wager sits a bit higher relative to the rider's butt. Take a look at the seat on any pro stock drag bike. Notice the two positions available. They are there thanks to wind tunnel research done by Pizza John Maffaro back in the early days of pro stock bike. He found, that by sliding back in his seat and humping his back up, he was able to gain nearly 4 mph in the 1/4 mile with no change in HP. That was back in the day when 160 was really fast for a PSB. One of the reasons the Busa is faster than a BB is due to the hump behind the seat. It enables the air to close more smoothly behind the bike. HP requirement goes up as the cube of speed increase. Taking a stock Blackbird as an example and using a fairly high average of the RWHP figures I have seen. RWHP=140. Top speed at 10800 RPM is 178 mph, HP limited. To go from 178 to 200 mph is a 12.36% increase in speed. Or 1.236 x speed. 1.236 cubed is 1.418. Multiply that by the 140 HP and you need 198.6 RWHP to get to 200 mph. This is probably not quite correct in that at 10800 RPM, a stock BB is well beyond its power peak. You would have to extraploate from a dyno run to determine the HP at 10800 and then apply the 1.418 factor. |

200 mph on stock body,ride height,etc ? Stock one does 175,200 would be a 14 % increase,cube that and we get about 50 % increase in hp to combat aero drag.Plus rolling resistance ( wheel bearings, tires,chain),but that is much smaller part. I guess you would need 200-210 rwhp to do honest 200 mph. Motogp bikes are barn doors,at least kawi,Yamaha and Honda are.Ducati looks pretty areodynamics,part of the reason Capirossi speeds are so high,of course him being a midget helps |

When Mark Moisan produced the XXX Blackbird Turbo kits with Aerocharger Turbo's, his bikes produced 220 HP on high boost (180 on low) and were geared 18-45. His streetbike radared at 200 MPH as tested during Bikeweek at Daytona by a couple of magazine guys not to far out of town. The bike then appeared in numerous mags, both here and abroad. This was around 1998. Don't know if he ran out of gear or HP. Thats about the best example I can offer from real world riding/testing. I can tell you that Dave Owens set a record at Bonneville at 220 MPH on a NA 240 HP Hayabusa...I'll let you guys adjust that for altitude and traction. I was at Motorheads shop in Cleveland recently and his #1 mechanic showed me a GPS screen on his TurboBusa.....234MPH, done within a mile from a standing start and running out of gearing.That was on low boost, or about 375HP. High boost on this particular bike yields about 500 HP, or roughly the same as Kent Stotz's Blackbird. Motorhead rode his Busa streetbike to Bonneville and qualified for a license and went on to set a 246 MPH record. Sorry, I don't know the HP on that one. There are some real numbers to kick around.....Whaddya think??? Hey Shovelstrokeed...funny you mentioned PJ and the seat.... He lives 10 minutes from me and is a wealth of knowledge.. Quite the character and a drag racing legend. Last edited by HANKSXXX : 12-31-2006 at 1:07 AM. |

I didn't get back to this until after shovelstroke had already posted up, so.... yeah, what he said.  When I say absolute shape, I'm taking into mind more than just the front fairing shape. All kinds of interesting things come up in wind tunnel testing that have little to do with the stock "look" of the fairings and such. Again, the NASCAR has the same stock "look" to it, but a subtle 1/2 inch lowering here, 2 inch stretch there, etc., makes all the difference. At those speeds, I just don't think it all is about horseys. Otherwise, the 1000 BHP indy car should be capable of hundreds of miles per hour faster than it is.

When I was more in to high speed runs, I could hit the wall, then slide my butt back, squeeze the seat with my thighs and pick my butt up off the seat, and watch the speedo and tach needles move up, gaining about 4mph. Do that too fast, and the front end gets to weaving.....which is too much excitement for my thin blood. |
