A few housekeeping items:
MAF idea is dead. Can't get a California emissions ECU that isn't a horrible P.O.S. Megasquirt/Microsquirt or Speeduino it is. Anyone wanna buy some 2.9 MAF sensors? ?
Found a Merkur Scorpio air box. When it arrived, it was a lid and tubes. No box. Freaking eBay... So, found this on amazon:
Not exactly an elegant solution, and waaaay too freaking expensive, but it will let me use the Scorpio plenum with a stupid cone filter for now, and attach the intercooler plumbing later.
I've done some reading on throttle bodies both before and after the blower. Have read pros and cons for both. Interested in opinions.
I am planning on running the blower with its electronic clutch and use the Mercedes bypass valves for boost control and to kick it into natural aspiration for idle, same as it was in the C230. If I can't get the C230 bypasses to work, Bosch apparently makes mechanical ones that are respectable.
I had considered using the electric fan relay on the Microsquirt to control the supercharger clutch. Not sure if it would work; would depend on the input parameters. If not, I chopped a MSD rpm switch out of a riced-out Nissan at the boneyard the other day. SOB had a nitrous kit on it. Looked like someone had beat me to the bottle, and whomever grabbed it took a pair of bolt cutters to all of the like-new steel braided hoses connecting the kit into the car. Why you would ever chop up all that good tubing... Guess ricers all have the same level of intellect.
