Since I had to tear down my partially built engine (to have the case decked), I have a second chance to choose a cam shaft. This build will be a 2056, target compression ratio of about 8.6:1, and the complete EFI and electronic ignition from the Dub Shop (based on Megasquirt 2).
Any wise suggestions? |

The cam the type 4 store currently markets for being slightly more aggressive yet compatible with FI is the 9590. I've had one in a 2056 with D-Jet and now in my 2270 with microsquirt. It's excellent, with the possible exception that the first 30 seconds of a cold start require some throttle feathering. It really wants more air than the TB can give it when stone cold.
On the 2056 I was running 8.6 and the 2270 is 9.0. Same situation on each, although I think Jake said it really isn't designed for CR above 8.5 / 8.6. I've seen others say similar things, so it's likely not just me. |
