Dam that's a big statement.. So the Sibler is not performing like it should or is the Poo clutches that much more efficient over the pdrive, since you should be making a decent more power from the 850


I all aspects. they are consistent, they are easy to service, i can tune it in under 3 min without removing the primary from the machine, i can remover the secondary and service everything behind if need be, me clutch heat issues are virtually non existent anymore, the track speed is faster, the infamous etec turbo bog is no more from a dead stop full stab and it lights rite up. i can go on and on. Im gunna go out on a limb and say my 5lb xm with the p85 and team will give an 850 turbo at the same boost with the stock ****ty doo clutches and embarrassing spanking. I can say that because i have an 850 silber turbo...

Well, im gunna blow ur mind here for a sec. the silber works perfect, Theres a misconception the 850 makes more power then the 800r..... if that is so can you tell me why and 850 mpi with 5lbs boost runs the exact same pin weights as my 800 boost it 5lbs?
Exact same clutch set up. Now i know your all gunna wanna come on here and call me out on it BUT! the cvt's done lie. on a side note, yes... that was a big statement for me to make, and i wouldn't do so if it wasn't true. they are more efficient. For me ill never run another doo clutch again.

I believe what your saying, but your the first I heard saying it.. Good to here the Sibler works well, so does the clutches makes the difference or is the 850 a under performer?

i been waiting to compare the motors as well, but never had a chance yet..

The motors are only 6hp difference. Not quite enough to warrant more pin weight.

im thinking they are the same HP... i dunno. all im saying is the clutching is the exact same from the 850 at 5lbs to the 800 at 5lbs. U would think with the extra volume in each cylinder you would be able to make substantially more hp based on the amount of air and fuel you can fit in there compared to the smaller 800 cylinder.
