That's just incredible, Mike. I can't fathom being that good at precision machining. Once you finish the mechanicals, let's outfit your car with a slick livery to promote your company, or whatever you want to promote, and get this baby in a magazine.

Parents, take note: This is what happens when you give your kid a Dremel for Christmas...
Mike, this is pure engineering art. Please take and share plenty of pctures along the way. Call it **** for us old folks.

Very impressive work!
640 WHP without boost.
I did a lot of CNC programming with Mastercam and setup on machines. I like the big Horizontals as the chips fall down. Your machine work looks great. What $$$ for that? 6061 T6 plate?
4spd is fine. I have a '62 Jaguar XKE (2400 lb) with a Chevy 327 and a 3 spd, 2 and 3 is all that is necessary. Just bought hubs for the back to replace the wire wheels with disk as got tired of popping and replacing the wires.

It's 4 and 5 inch plate, several hundred dollars, I'm not sure.
I do like to use 6061 and avoid 7075 for exposed parts, 7075 is very corossion prone.
There's also a heat treated chrome moly insert that holds the pinion bearings. I feel it's important to have stable, precise mountings for those bearings, they'll see big power and spin over 7000 rpms!
I mentioned having fallen in love when the BMW 850s came out becasue it had a 6 speed. I did own one and drove it as a 3 speed normally and I understand others do the same, 1-3-6. The other gears were pointless.

Not only is this very very cool, but it might be salvation of 928 racing. I was starting to think that these cars would just be transmission limited and there would never be any possible solution.
