Supercharger build up

[Shadowbug]

Gut my megasquirt today and have begun assembly, also rebuilt the supercharger, powdercoated a different color too.

first order of business after the megasquirt build is the intake manifold, plan is to build it so I can bolt the TB directly to it in order to run N/A and get it tuned in, then add the Supercharger. I need to figure out pulley sizes to drive the supercharger at the correct speed, cause the teflon coating begins to melt at 14psi, which is WAY higher than I want to run it, I'm thinking 8 psi is max.

I wish I had my own machine shop, or at least a Lathe, it would speed the process along considerably. Pulleys and the toothed wheel for ignition need to be machined to get it all working together.

Sounds like a lot of fun!!! Get those pics up so we can ride along with you on this little fabrication journey.

finished the workover on the engine, the guy who I had build it did a pisspoor job putting it together and there were a few issues I wanted to fix before putting it into service.

#1 oil leaks, brand new build and it leaked like crazy, so I dissasembled the top enf cleaned everything and redid the pushrod tube seals, Beadblasted and powdercoated the pushrod tubes, and coated the seals with silicon before reassembly. also did the picup plate and the othe plate on the bottom (I think it was for some industrial application)

#2 oil pump, rather than doing it properly the builder opted to grind down the heads of the bolts holding the cam gear onto the cam. and when they still hit, he cut a gasket out of thick rubber to space the oil pump out. of course when you tigten the oil pump down the gasket squishes out and provides no seal whatsoever. so I pulled the pump and ground a little off the back side for clearance, slid it back in with a regular gasket and clearance is fine.

now that the engine is back together and hopefully drip free, I will begin on intake fabrication. I rebuilt the supercharger (it was a matter of replacing bearings that couldn't be found anyware this side of japan) and will need to fabricate mounts for it, as well as machine the ignition pickup wheel/pully to fit onto my engine, and find matching 6 rib serpentine belt pullies to use on the supercharger and altenator.

so I do have my work cut out for me, but things should be strait forward, as I know where to get the pieces I need, but have to get most of them machined up to fit with what their intended use would be. I wish I had a Lathe at least.

the pulley setup I was running with my porsche fan gave about a 1 to 1.5 ratio on the altenator, Jake Raby figured this was too high, would a 1 to 1 or a 1 to 1.2 be alright, cause it looks like this wouls be the easiest to do
