I highly doubt 10psi will do any thing to the blower. I'm hoping to be able to purchase this kit in july as a birthday gift to myself =)

Although, getting 10 psi out of this blower will be pushing its efficiency limits.

The blower, no. The motor, boom.

The intake pressure ratio is not the only factor in efficiency. The compressor's efficiency map is looking at pressure ratio versus airflow (CFM). The F20C is going to have much higher airflow than the Miata engine, given the larger displacement and a much higher flowing head. As such, the MP62 is restricted to lower pressure ratios (and therefore boost pressures) on this engine.
The MP62 is going to be limited to somewhere in the vicinity of 330 RWHP. If you want more power than that, start looking at turbo kits. The MP90 is too big for the F20C, realistically.

I posted on the BR forums today asking about some specifics, I am curious how this setup will work on a built motor with a lower C/R?
Also, I spoke to Eaton today and they said the MP62 has a rpm limit of 14000 but many have spun it past that mark and he just said it would shorten the blowers lifespan. No one has said what this blower can produce in the way of PSI !

FYI for those still anxiously waiting, BR is still "tweaking" the kit a little bit. They are working on a new bracket for the blower because after more testing, it showed some signs of bending. So, thicker material and more bracing is in the works. They are also looking at using a W/A intercooler instead of the A/A one because of some drivability issues they encountered after a few weeks of testing. Brant says it's providing the same intake temps with better throttle response and will be easier to install. They're also working on the final fuel maps for the ELF. Other than that, he says it's close for us beta guys.
