210psi running 93 octane
To prove a point I have decided to cut some heads to try and find a squish angle that will be cool enough to run 210psi on 93 octane.
My plan is to lower the entire squish angle another 2 deg and cut and recut the deck to give me the compression. I dont think this is going to be good for turning a lot of rpm's but it should be an animal on bottom end. I think a simple prop up will do the trick for the speed.
anyone ever went this route?Input would be appreciated.

That will be the highest compression ever run on 93 octane, it should be interesting.

Thats compression is common place on the stand ups and smaller skis since they are never in the throttle for long period of time.

raise those exhaust ports with that much compression you"ll get your rpm's- been there done it and will probably do it again-the sound of a single pipe 65u screaming at 7400rpm's is intoxicating and... rather fast

Hey j, you should race mark from 0 to 60 or run him 500ft. That should be a race.
