fastest banshee

[Hilarious]

the fastest banshee i ever saw went like this.....

[andrew3160]

I WANNA GO FAST!!!!

 

You know how it goes, if your not first your last. Just put one of those belt driven super charger thingy's on your banshee, bet you could do 120 then.

[overrevtricky]

this is all mad lolz! Why are u defending this 90mph+ claim so hard?!? unless u got yourself a BEAST of a machine ur not doing that speed. Yeah it seems fast as shit but actual speed will vary. How about u jump on ur 90+ rig and RIDE it instead of boasting this BS on here?!?! at this point ur doin 100+.............on the interwebs!

This is kind of interesting, got this from a professor at my college.

 

Hi Steve,

 

It's possible in principle to determine the top speed of an automobile using information and calculations, but you would need to know a huge amount of information: not only the tire size, engine rpm, gearing, etc., but the aerodynamics of the body, including the underbody, and the amount of frictional power loss in all of the power train components, from crankshaft to differential to axle, etc. You might even need to know the quality of gasoline used, the kind of carburetor, etc. I imagine some people have tried to put this all together into one equation, but unless you get all the various parts characterized very accurately, your final result will be a poor estimate, maybe even garbage. A car is a very complicated system! It turns out to be much easier to take it on the road and test it!

 

On the other hand, if you're working with a system you mostly understand, and change just 1 thing at a time, then a calculation (or better, a detailed computer model based on physics ideas) will give you results much more cheaply and quickly than building a revised system (lots of expense) and running a real test. That's why, for example, Boeing runs its new jet airplane designs through a computerized (simulated) wind tunnel before they build a life-size unit and run parts of it in a real wind tunnel, or actually try to fly it. The computer simulation might not be really accurate, but it's so much cheaper to do, and it can catch gross errors, so when the real-life test comes (the way to get accurate results) the results are likely to be workable, at least.

 

To your second question: Physics, like any other natural science, tries to understand parts of nature. We sometimes gain that understanding by just observing, more often by experimenting, and occasionally by just thinking and theorizing. We often express our understanding in theories, using mathematics and words. So a major result of doing physics is a set of theories, but physics is more than just these products. It's also the set of skills that enables people to investigate new things, and to know how to create new theories (about whatever is the current object of study).

 

I hope this helps!

 

Best regards,

I would like more (friendly) discussion on the first part. There will be power loss as described, due to heat and friction. BUT if the crankshaft [thatturns the transmission - > that turns the sprocket -> that turns the chain-> that turns the rear sprocket-> that turns the axle and tires-> that move the vehichle on the road] spins, the tires will also turn a simple calculated number times per the gearing chart, regardless of power loss to the rear wheels. When the power loss occurs (due to the above examples) it will limit how fast the engine can turn, thus limiting how fast the tires can turn. The vehicle cannot slow down without the engine rpms slowing down, unless there are tires spinning, transmission slipping, sprocket or chain skipping, or cluth slipping. If I am wrong please give an example that goes against what I have described. My math and physics are rusty, so I could be looking at this situation all wrong.

[papa_smurf49319]

okay what your prof said is very ture. But im pretty sure the calculator that we are using DOES NOT take into consideration losses threw the drivetrain and environmental factors. Its a best case example!

JESUS.... i dont know this dude but i can tell you that most of you are being complete jackasses. he never said the bike was stock, all he said was stock carbs and he didnt list the mods. If its .040 over already its pretty obvious the bike has other mods as well.

 

 

he ALSO never said he had stock gearing. his very first post also said 15 42's.

 

 

 

 

yeah he needs to work on his debating skills but some of you jackasses are putting words in his mouth and then calling him a dick head for these magical words he never spoke.

 

 

and yes, i read through all the posts. he never claimed 120, he never claimed anything in the quarter mile, he said he was on a long ass road in the middle of nowhere.

 

 

and also, for the jackasses saying it defies physics but then also saying that a GPS isnt accurate????? LMFAO... really guys??? really???

 

 

GPS is 100% positively accurate so long as the road is 100% flat with no elevation change. Once there is an elevation change it is no longer accurate because you are no longer moving on the X axis but also on the Z axis as well. BUT technically you could still figure out exactly how fast you went based on how far your traveled and if you could also pull the elevation change out of the GPS as well. (good ole pathagorian formula)

 

 

 

 

anyhew....... if your going to flame him at least flame him for what he actually said.

ALSO.... he is 100% correct. Tires grow, quite a bit, as speed increases. ask me how i know..... (the slicks on my Z06 grew about 2-3 inches when strapped down on the dyno and made a pull, it wore down my inner fender wells so now i have to clean the damn things out every time i drive it)

 

 

 

granted.... these were 28" slicks and aired down which allows them to grow quite a bit. but he is correct. tires for sure 100% grow pretty dramatically at speeds.

I know for a 100% fact that mine goes 92 with stock gearing.

You people need to get a fucking life!!!! I don't know who is dumber, you for writting this thread or me for reading it.

Dude, it is the internets. What did you think you were going to find on a 7+page thread on a banshee forum? Only Tits and BS get those kind of hits.....lol...

Not really just means hes done a few top end rebuilds.

So lets keep into consideration, if people are saying that you must have a 22" rear tire to hit 90. Well if 20" tire expands 2" which it very possibly could (or at least i think it could) well than would that in theory make the tire 22" at full speed, which would make it more possible to hit 90 correct? I don't know, all I was stating was what I was clocked at with my modifications. I never claimed to hit 90 with a stock motor, my motor was setup to have 85hp directly from GRR. Now if it has that I don't know Ive never had it dynoed, it sure as hell feels like it considering I race SnoX with a sled that has 150hp and the power comes on just as strong. I do have stock gearing, never lied about that. Whether someone wants to take my word for what Ive previously posted, well that's up to you. Ive been a member to this site for a long time, way before 2002, granted I haven't helped as many people as some, but Ive always been trustworthy, never lied to anyone or screwed anyone over.

 

i have 22" tires.. they measure about 20". most atv tires do not measure what the tire says on the side. just saying.

Yeah, I sold tires for 5 years...Wheel and Tires sizes don't measure out to the exact inch they say.

BACK THE FUC K UP!!! Wait....Forget the 90MPH story....Your claiming 85HP on that totaly mild build!???? AN Unported 421 cub makes 88HP on gas!!! Your not wrong....your clearly insane! You keep falling back on the whole "It's not stock" story. Well listen pal, I'm running a 472 Cheetah motor with full race porting, custom cut dome from Titan racing, power valves, CPI Big Bore In-Frames, a JJ+A axle, 15-43 gears with 77 RO tires in sand and Knobby tires that say 20" on the side, but measure 22 1/2" true for dirt,(My original set said 20" on the side but measured 18") all this is mounted to A full chromoly metal tech frame and my bikes weighing in at only 310. Your bike is nice...but it ain't nothing. Bikes like yours hit craig's list every day. My wife has a 370 Long rod motor from D+M Racing with Doug's porting and custom cut domes that will run circles around yours. Forget the speed debate, I've figured you out....you are in Europe aren't you? Because you must be working with the metric system if you think your ANYWHERE near 80+HP. What have we had now... 2-3 guys who think your not on dope? I'm going to admit it...you got me. You really did get me. I totaly got sucked into your game. You managed to get alot of people all riled up and trying to debate you. But now I see....your just one of those guys who spends pages and pages of posts telling people that you don't care what anybody says or thinks, yet all your doing is justifying yourself over and over again. Ok....I think we'll all just take our toys and go home and leave you and your other attention craving speed jockey's to BS back and forth while we go out to ride our REAL HP Chariots. I'll go back to planning my dune trips, my dragstrip trips, work on helping the BansheeHQ glamis trip off the ground, post up some BADLANDS dates, and you can go back to racing up and down the street. If your bike makes 85HP...mine must make 200HP. If you can do 90+...fine, let's say you can. Let's also understand that if we all lined up side by side on your street and raced....buy the time you get to 90 most of us will be a block ahead of you, pulling in clutches and turning around. Take it easy there Evel Kinevel. I'll keep an eye out for your vapor trail........Think I'll name my next race team "Garmin Racing". Seems to be the hot new trend

[White97Banshee]

I dunno my buddy got a trailtech with a speedometer on his trx450 and he tops out at 75.2mph in 5th pinned and i pass him by at least 5mph in 6th pinned on my shee that's got t5's pods and vf2 reeds. also .40 over if that even makes a difference.
