SM is definitely only for the adventurous. But that's whats so great about it. Every year its just like a car show to see what new craziness the other guys are doing/have done.
Stuff that would just seem over the top and dumb in other classes is right up our alley. Like the S2000 with the "rocket engine" which I think is something about porting fuel to the manifold to spool a big turbo. Or the sequential trans in the Subaru from Colorado (drawing blanks on their names). All the aero, carbon, billet, electronics, 500+ hp, widebodies.... Gets me excited just thinking about it

Why do you think I've been codriving an FS M3 for the last couple seasons? Way cheaper to operate... although we chew through a set of tires in about 60 runs. I can't really foresee SS being any cheaper... rear heavy, rwd car and all. That and 305/30/19 RE71Rs are not cheap by any means. It's almost like buying Hoosiers all over again.

2 years ago at crows tour I was about 85mph coming into the back sweeper and 3 years ago at Nats I had to shift to 3rd 5 times. That left course (cant remember east/west) just totally screwed with my head trying to downshift that many times.

Do you have a 153mm rod on the 94mm crank? If so, it's good to 9500.
I'm revving to 8200 on the 2.3l and on a 25.3" tire. Local events I keep it to 7500 but let it stretch for bigger events if I need it. That puts me at 70.X mph but I think next year I'm switching back to the 285 to get lower and will swap to 4.31:1 final drive ratio which will put me at 72.X mph.
I should probably also pull the motor after this next season (3rd season on it) and just inspect things, replace rings and bearings, re-hone, etc. But its been pretty rock solid so far.

I would magnuflux the crank as well. Measure the pistons to make sure they are within spec. The 100mm crank and 150mm rods beat the **** out of everything.
Absolute power corrupts absolutely.

Not saying you're wrong, but my stock 2.0L rev's to 8k for 30 minute sessions. If you needed extra RPM to stretch a gear at the end of a straight, I'm sure your motor can handle it.
