I`d say some long term testing would be in order for liability issues.
some would think a couple bens for 16 hp increase would be fair.
looks-size-complexity-etc would sway a lot of buyers too.
Good luck in your endeavors.
I've been doing this for 35 years now. There is no issue with mechanical failure, carbon buildup and they are stationary. Changed the design over the years quite a few times. This was the best sustained boost I have gotten. Though I agree it needs more boost to be of real value. I'm working on a new design to increase the boost throughout the full RPM range.
They look cool, I'm working with about a 5/8ths in spacer which is needed for the butterfly clearance, and they are very simple.
Thanks for your input, I appreciate it. I need all the help I can get...
