I saw that same pic, that pic was stupid, it was fake, i can tell, you just have to look at it good. there wont be a 500cc 2stroke banshee with that high top speed, they arent allowed to do it.

 

Snowmobile engines are pretty insane. I'm betting it's the Polaris 700 triple? I heard about that once. I am into sleds and quads and hopefully one day, I'll modify a quad with a snowmobile engine. I'm thinking of putting a nice Ski-Doo 800 Twin[img]i/expressions/face-icon-small-wink.gif[/img]
Heh, I have a 583cc Ski-Doo and it flies, and I imagine an 800 in a quad would rock!

 

stock, quadzilla or maybe ds650, i know the DS's do about 80, im not sure exactly how fast the zilla goes. but modded, theres no end, i saw a pic of a "banshee" (the only thing banshee about it was the front plastic) with a huge jet engine on the back, i bet that thing hauls, lol.

 

i doubt it "hauls". i bet it flat out flies! [img]i/expressions/face-icon-small-smile.gif[/img][img]i/expressions/face-icon-small-happy.gif[/img][img]i/expressions/face-icon-small-tongue.gif[/img]

 

id say a yamaha breeze....falling out of an arplane will do about 120mph before it crashes.

 

johnny was that quad called the kamakazi? i seen one at national trails drag strip during the spring nationals here in ohio it had a jet engine on it. that thing was wicked

 

fastest quads(not in order)
Quadzilla 500
DS 650
Kawasaki tecate 4
Yamaha Raptor
Honda trx250r
quadracer/lt 250

those are the fastest in my opinion

 

i dont remember the name exactly, but kamikaze does sound familiar, wildman.

and hwytohell, i cant believe you forgot the banshee! its just as fast as a raptor.

 

are we talking stock.. because i dont think a 250r is gonna beat a shee on top end stock.. i could be wrong tho..

 

i know i would like to see one
