whats the max HP a billet banshee transmission can handle?
when the hp gets to 200-250hp do they just start to be totaly unreliable?? Anyone know the hp at which they get unreliable? What hints do you have to make them last longer? I just dont want to tear the engine down every 10 runs to replace shift forks or gears...want to do it right...once...
Thanks!

just depends , they have the ability to hold 400+ but like anything out there at 250+ when things go wrong they go very wrong , my twin 1200 has never even burnt a fork but the 4 cylinder has ripped 9 trannies apart, the triple has been relatively good on tranny parts, its between 250 and 300 the difference is weight of rotating mass and how hard you hit it IMO, just some clutch work on the quad and it has done good on forks and gears but I promise if you loose a chain or something similar 400 hp wont even blink an eye and grinding metal meat most all of our trouble was caused by a separate incidence.

you wont have any problems with a charged 535 overpowering the tranny, not saying you couldnt hurt one but the tranny itself is strong enough

Great info The bike will be 290lb's... drag slick... wierd, I thought the banshee transmission was weaker than that?
for 250hp...can I just use a billet second and cryo the rest? Do folks use billet seconds because they are the weak link?

he is talking about a full billet robinson tranny

LOL, so the billet tranny can do 250hp no problem...... got it

On a side note....anyone ever use a harley transmission on the banshee? I was looking at doing that with a snow motor.. but it would not fit my frame. Seemed like a great option. Tranny is cheap and tough...$2k comes with under cut gears, beffy setup ready for drag racing. Maybe with the big hp motors it would be a option... simple to repair, no need to split cases every time the tranny messes up? Has it been done??

oh man lol sorry bout that i just assumed thats was what was meant with numbers like 250 hp I did run a stock banshee tranny with a billet 2nd on a almost 200 hp cougar it did pretty good till I rode it lol it let 4th go. for the most part any thing over 160 i would go full billet, either the 5 speed or the 4 speed, if you are wanting a 1/4 mile pass the 6 speed from Robinson does good

the biggest problem with other trannies , and I do know of a couple of guys who have tried is the ratios between gears are never in the right ball park.

I think Packard did something with a baker tranny years ago. But not sure on the setup.

triple heat? I believe. that is one of my favorite bikes I have seen but I think the ratios just keep it put up we are limited to a 2.36 primary ratio

Ya, with big tires out back.... ive got 236 gears in both my 535 engines...motorcyle drag bike...17 inch slick.. goes through the 1/4 traps in 6th.. with a real small sprcoket in the back! I think the baker tranny can be setup with diffrent gears...I was talking with them the other day... anyone got a pic of a bike with this setup? Wouldnt that be sweet to never crack the cases again for a simply tranny issue SWEET...
