Will 300 mph ever be achieved on a open streetbike?

[2fast4u2c]

300MPH is not only possible, but achievable.  Bill proved that with his 296 run.  Getting the right traction and power to the pavement while keeping the front end down will be the key.  Aerodynamics and chassis design are going to be the critical factors.
I think we will have that figured out and will give it our best to make that number come true.



Front end is just about done.  3-D scanning will be next for virtual wind tunnel analysis then its off to the actual tunnel.

And nobody in their right mind would bet against Larry, either!

I remember Scott Guthrie telling me years ago that there was nothing that could make you sit up and take notice more than seeing a "Larry Forstall Racing" sticker on the bike sitting next to you.  We felt the same way about seeing Scott's stickers too!

Walt, hope to see you there at Wilmington soon.

I remember the boards at the time of his big record run. No one except Bill thought he'd bust 300 much less go ( what I say ) 312. It's an awesome feat that will be remembered. I don't think Bill will be forgotten either.

[knecum]

All I will say is good luck, be careful, and godbless you. I don't know who's gonna do the riding but they better have some massive balls. That's going to be some big shoes to fill Guy. I don't think 300 in a mile is going to be any milestone that means anything to anyone except being a personal goal to that person. 300 is 300 wether its 1,1.5 or 5. To the everyday enthusiasts its just a # that has already been achieved. They don't care about the distance. So just make sure its really something you wanna do and be willing to risk you life for just bragging rights. This is not your everyday 240 mph amusement park ride that's a blast, its down right scary stuff. Good luck to you !!

[2fast4u2c]

Its not about bragging rights anymore because it's been done.  Its about the journey, but I will say that I have made the decision that if I reach it, I'm done.  No number beyond that means anything to me, this is a personal thing now.  I may not make it, but not for lack of trying.

Oh, I'm riding it of course.

.   I hear ya Guy, its just some serious speed that if you never really been that fast you have no idea how hard its going to be. Also you may or shall I say will have a comfort zone that may be well below 300, mine for instance happens to be around 250 naked and faired.  Those type of bikes that you go for rides on are totally different to ride. I feel way more at home on regular style bikes and had bad experiences with the handeling of the other style. I know your taking your time with the build as you should. Taking your time reaching those speeds just as important.

[2fast4u2c]

Slow but sure wins the race. You are so right Steve. Baby steps.

[Got-Busa?]

Guy, what is your fastest speed achieved?

[2fast4u2c]

228 felt like a really slow pass.  I haven't been on the track in awhile now. Chassis has never been tried. New program, I've never done turbo, so I have a lot to learn about going fast. Baby steps. My runs will be well regulated by many.
New gear, new leathers, new body armor, new technology and a new power plant. This is a journey.

[gsx-rboy750]

A journey to 300 without a intercooler instead using nitrous to cool??? I want to see it but I think with your frame design which would allow for a big intercooler Air/water or air/air  behind the front wheel will be your first learning step. IMO

[2fast4u2c]

There is a method to the madness.  It's all in the tuning.

There is also something called heat, time and metallurgy.

[2fast4u2c]

Yes and as a great Dragracer Elmer Trett once told me, you go faster burning fuel than aluminum.

[Commuta_Busa]

Bill was only retiring from pavement. What he could have done on the white stuff we will never know. A turbo, methanol, tube frame chassis is resting at the farm, just needs a body. DON'T ever bet he couldn't get the "number" out there. LSL

I was counting down the days for bill to get off the pavement and just do the salt to set the mark.

[ADMIN]

Further thread resurrection (again) due to quality of posts, momentous accomplishments and legendary nuts involved, hairy or otherwise. Proud to be able to say Bill was a friend to many of us here, and the SuzukiHayabusa.org decal on his bike is still the fastest open wheel sit on motorcycle forum decal the world has ever seen. Enjoy.

To add to the perspective of this thread Ralph Hudson is in a SLC hospital with serious injuries and I hope recovering without complications. Ralph qualified at almost 270 and was on his return run when it appears that a gust of wind caused a tank slapper and there was no saving it. Ralph runs gasoline and thus has less power than the methanol bikes. His fairing is the best ever also proven by the unreal speeds of his 600.  Ralph is 69 years old, certainly a record for age/speed. As I have said before "This aint golf" it has consequences.  Get well soon Ralph     LSL

[Frank06]

Ralph is one of those people you just have to admire; I hope he recovers well (and soon) and can continue to pursue his dreams.

I think 300 in the standing start mile is achievable but all the stars will have to align, it certainly isn't easy but records always seem to fall, sooner or later.

We should remember that the famous JOE AMO went 272mph AVERAGE for the 2nd of three timed miles at Bonneville 10-15 years ago.  Based on his entry speed, experts have estimated his TOP speed at about 284mph with only 1000cc.

It was very enjoyable to read the first pages worth of comments on this thread haven't seen it since it was originally written... 🥲

[FlaminRoo]

At this time with the benefit of hindsight I guess the question is, are our modern sportsbikes (oem chassis) equipted with "full" bodywork, considered "safe" enough to attain speeds in excess of 250mph, indeed approaching 300mph ?

[scott g]

I would think that with suitable modification to
chassis and body, 325mph speeds would be reasonable ...............

[Frank06]

Aero controls ultimate speed and at Bolivia speeds exceeding 300 are very possible without big, big power. All the details better be right though!

Remove the word "suitable", replace with "extensive" 

Unfortunatly, both men who have achieved 300+mph are no longer with us due in part to handleing issues on modern sportsbike geometry with "bolt on" modifications,,

Modern Sportsbikes are constructed to have fun in the Twisties,, Top Fuel bikes have evolved (from sportsbikes) to go extremily fast in a straight line,,

I suggest an extensive rethink on machine stability at speeds over 250mph is a "Priorty",, rake, wheelbase, lower c of g, and that's even before we start thinking about slippery bodywork
