Yes and no. What is the strength of the 9R? Fast revving and more low end torque. What is the weakness of the 850 Boost? Slower revving and lower low end torque. Marry the 2 and you gain plenty. Eliminate the 850 boost because the 900 Boost will be an ideal design even if Polaris uses the heavier crank for durability.I've never understood why everyone is obsessed with the idea of a 9R Boost.... wouldn't alot of things that make the 9R good be an issue with boost? High compression, lightweight pistons... and basically everything else? I think we'll see a new ground up turbo/engine package eventually... not a 9R boost.
I guess Burandt runs one. Who knows. Probably not me.
