Can't figure out how to upload here. I mean I am a cave man running a carburetor LOL
I just noticed I hadn't made any update since the little detonation party I had in cylinder 3.
To fix that issue I got some deeeeeeeep dish pistons and some forged eagle con rods. Compression should be on the high side of 9.4:1. Before the compression was about 11.1:1; thats kind of a lot for 93 octane and 8psi of boost. There is a weee bit of detonation now; only after a good heat soaking on the highway. I might be able to dial the ignition timing back a hair and fix that. I might be investing in an ignition box to control timing a little better, but for now its good enough.
Fuel ratios are a little fat. 8:1 at wot... I'd like 10:1 but I wanna get the ignition sorted before I start pulling fuel out. This is my first roots blower, and from my experience so far the heat soak is real LOL. You do a few pulls and everything is super, then the intake gets warmer and warmer....
