what does it take to make 150+ hp

big 535 cheetah PV on alky won't do it?

that would do about 120 to 130 I think

RDZ posted a dyno run of one with block offs on his site

here is a link top one is a 10mm cheetah bottom one is an 18mm twister

do you think those motors are triples?

That's pretty much my thoughts as well. I have to be honest...I've seen some Cheetahs flat out rip, but some are just turds for what they are.

I've never seen them as consistently fast as they should be like the cubs are out of the box....

 

On all motor, no...a 535 cheetah isn't getting to 150 HP. Not even on the most generous dyno in the country.

well, I think someone should be studying rotax engineering before they design a cylinder for the banshee....or cases as well. They seem to get tons of power out of very basic set-ups....i found a guy who put twin pipes , big carbs, and some port work and made 153 out of a 583 motor. I saw a set of banshee cases machined to fit a rotax engine on ebay the other day. I WANTED THEM....670 rotax banshee worked over with the right pipes would make that all day long. i just figured trinity would be making more power with there big dogs

 

just a thought... the right twin would make that easy

[dajogejr]

Sleds need to make that kind of power, because their CV transmision and huge track suck up literally 50% of what is taken from the crankshaft.

 

Now....are you talking Crankshaft HP or rear wheel HP?

If you're talking crankshaft HP, then yes...a 535 cheetah will probably make 150 HP, give or take.

But there is a calculated loss going through the clutch, transmission, chainwheels and rear tires/axle.

 

So...apples to apples here. I'm 100% certain a 583 Rotax motor with minor work did not put out 150 plus HP through the transmission or to the track.

 

When I quote or read HP numbers for the quads, I think and see them in real world, rear wheel numbers.

[TurboBanshee420]

yeah i think it was a jackshaft "land & sea" plate he used, so....yeah take 30% off for the cv and maybe 12-15% more for the track and resistence.

 

but not on a banshee trans!!!! take maybe 20% for all of it and call it dill pickle right there.

[dajogejr]

Yep...so a Cheetah that puts out 140 to 150 at the crank is probably 120ish at the rear tires.

I would agree with 20 to 25% loss from crank to rear wheels on a banshee trans.

 

That's another reason why you see guys that run snomo bikes building such HUGE motors. They need a lot more power to push the CV type trans and get the power to the ground.

 

Nice part about a snomo bike is consistency. No such thing as shifting too early or late, too much or not enough clutch out of the hole.

Time the light, pin it.

hmmm.... i have a 583.......

 

[sheefreak]

I would put my 10mill cub against a 583 any day of the week...

583 what?

 

Whoops I just read above.

has anyone ever posted crankenstein numbers?

[shanYE west]

Dont quote me.. but I think I remember 130's..

Snomo setup of course....Kinda missed he mentioned mated to Banshee cases
