What does it take to go 100mph?


Recommended Posts

I am going to compete in a local radar run on a frozen lake this winter, I want to run 100mph, for bragging rights more or less but I figured that would be fast enough for a win. I have a 99 banshee with pro circut platinums, no airbox lid, boysen superstock reeds, 4 degree timing adjustment, will have a fresh top end and *maybe step the cool head domes down from 22cc to 19, depending on funds. I will run 22'' tires on the rear, what size sprockets should I be running to achive this MPH? The question I should have asked first is do I have enough horse power to pull such tall gears to 100 MPH in 1000 feet? For you guys that have no experience with ice it is just about like running on tar when you have studs, it doesn't drag on your machine like sand or even dirt can, there is little resistance. What do you guys think?

 

I know I'm retarded, that can't be helped... I plan on using long snowmobile picks on the rear tires and ice screw on the fronts.. Any suggestions are welcome, thanks for the in put, Seth

I would say no not in 1000 feet and maybe not even at all. I have 14 41 gearing and 22"tires and on asphalt i had a gps on me at 90mph. I did this on a road which was between 1/4 and 1/2 mile. (guessing)

It will take tall gearing maybe 15 36, a lot of hp, and a good rider. Personally i dont think this can be achieved in a 1000 ft on a banshee on the ice. maybe if you start back a lil before the ice drag you can do it though. if i were you id be thinking about some ice water skimming on that beast and leave the dragging for the sleds. http://home.earthlink.net/~gellett/banshee.htm pulling that 6th gear will be hard in 1000ft

It's gonna be about a grand for every MPH. ;)

Thanks for the input guys, I think I'll shoot a little lower, It pulls about 75 no problem on 20" razrs so maybe I'll just change the gearing a little and throw the 22" on and change the gearing a little and shoot for 85-90 and see what happens, I'll keep you posted, I have a lot of work to do before then and of course the lake needs to freeze up haha

Quite honestly, no. You don't have the motor to go 100MPH. As said, you can gear a bike to potentially do 120...but without the motor, it's not going to happen. Banshees are about as aerodynamic as a cinder block...that works against you too.

No BS...take off the front and rear fenders to gain 3-5 MPH...we've done it at the 1/4 mile.

 

There is resistance, the picks have to penetrate the ice then come back out...from a rolling tire.

You're putting steel through solid ice...the ice gives...:)

You can see the rear tires I used off the to the side here. To be honest, after my bike went up the back of my buddie's leg on a pass and it looks like he got bit by a shark...I like to go and watch. That was a rough day...

We've got a lot of guys that go on the ice to drag here, it takes a lot more motor and gear to hit 100MPH...

Did he make a full recovery from that Dave? Yea, I want to have a drag racing event on my lake this season, but we will see... Might just use the trusty trail bike for a little added safety :huh:

If you have a weak stomach, these pics aren't for you.

The first was taken by our boy brady080 in the ER with a camera phone. The second is at the hospital 60 staples and over 100 stitches later. We all BS and exaggerate sometimes, but when I say it looks like a shark attack, I'm not kidding.... Be safe out there on the ice.

Frank did get vengence, however... A few months later, I sent my bike down for a buddy to just ride at Planet Sand 2008. Frank jumped on it and ended up taking 2nd in the class 0-475cc and took home some cash.

 

That doesn't remove the scars...but it helped, a little :)
