MmSadda's Non-Turbo (read: Supercharged) RX7 build

[RotorDad]

Were you planning on staying at 8 psi or are there plans for a smaller pulley & water injection in the future?

That's it for now! I'm actually pretty pleased - it keeps up with my buddy's new STi rather well.

Next stages will involve intercooling, upgrading the supercharger from 800cfm to 1400cfm, and porting the engine (or swapping to Turbo 2 rotors/housings/irons, and porting those.) I'm considering an aggressive streetport, but as time goes on I lean towards a bridgeport more and more.

Oh, and she's definitely coming to DGRR! Are you coming this year?

I think I understated things a bit earlier; it's supposed to be an 8lb pulley, but I'm actually seeing 9lbs pretty regularly over 6k rpms. I hope intercooling with an upgraded compressor wheel inside the supercharger allow me to run a bit more boost, more reliably. Reliability (within reason) and simplicity are two of the things most important to me in this project.

I hadn't really considered water injection, probably because I plan on intercooling, and I want to keep things somewhat simple.

Well this is different. How does it feel versus with a turbo?
