The fastest banshee I have ever seen, which doesn't say much, had the T-Rex top end on it. It was VERY fast. The only thing I know about it is that its a powervalved motor and it ran something other than gas, I think it is in the lower 400cc range. He had like a 4.1 or 4.0 in 300 feet. Being that it has a power valve might help the rideability of it.

 

Hey 14, You can also check out planetsand.com. There are alot of helpful people there who run some wicked fast shees in Utah. Ask Bansheechick she knows her stuff. I got alot of help on some alky carbs I had. They run some custom frame shees with 75+ HP.

 

To give the most HP avaliable, get the Hyper Technoligies Turbo kit. This kit makes 135HP, searously. All you have to do is of corse instal the Turbo, get different pistons, (Vitos power Pistons), convert to alchol, and instal Hiper EFI system. You will not believe how much it will eat 510cc stroker Banshees. Remember a engine basically stock designed to produse 40HP, putting out 135HP, is going to really accell the engine wear, the most common thing to replace, is the pistons, and the reeds. I've heard Vitos pistons work best, because they have a thicker skirt than most forged pistons, whick keeps the skirt from cracking. Vito's are also light which is what you want for a turbo enging that's wanting to turn 12,500 RPM.

An alternative is also to just convert to Alcohol, it's not too expensive, call a local race track, they usally know where to get it, a 55 gallon drum of alcohol will run you about $70. Believe it or not if you run it off alcohol the "correct" way you are making it more reliable. Heres how it does: with alcohols high latnent heat of evaporation, combine it with an EFI system, the EFI system highly atomizes the fuel coming from the injectors, making for a really cool running engine (150 deg).

Alcohol has a high octane rating, and can be ran at much richer air/fuel ratio, which usually adds 7% of power over gas. The down side of alcohol, is that it is very corosive to engine components, after just 12 hours of sitting, it has to be plunged.

Get the turbo kit and you'll be running 10.40 @ 114 MPH on asphault. this kit costs $5600, yeah it's expensive.

 

Hey 14 I thought you said you diddn't like the rink a dink. Finally glad you are seeing the light.

 

Hey 14mins, My friend has a 420 Long rod, port and polish, +6 swingarm, CPI out of frame drag Pipes, Dual 34 lectrons, alcohol, and lowering kit. let me tell you, that thing is VERY fast. But a friend of his has a banshee that has stock 350 bore, cool head, GRR drag pipes, and ported and polished very well. There are more mods but i cant remember them all. His bikes is faster than the 420! So you can make a 350 very fast without the expense of a big bore kit. Its all about getting it done right. Sorry for the long post but i hope this helps.
