Thanks for answering my questions, I appreciate it. I went back and looked at the first page, and I saw that it was already stated the setup included an external wastegate. After reading the 8 pages in this thread, I must have forgot.

What is your opinion of knife edging the crank? There is a service called "butcher crank" that does this, and takes 7 lbs. off in the process. Would this be beneficial to this setup, or is it too much material to take off? Would a less aggressive knife edge and a balance be better?

Assuming one were to do the agressive knife edging, how would additional lightening of the drive train affect preformance, such as lightened flywheel, carbon or aluminum drive shaft, etc?

Im aware of the rotational mass discussion, but the arguments go back and forth, so I'm not sure what to believe about this issue.

Any thought or opinions?
