[s-cars] Da Green Monstah goes back to da dyno

[Peter Golledge]

Hap

I'll second Cody's opinion, I'm running 400ft/lb in the LT-1Q which has been abused for more than
10 years in Auto-X, Steamboat, Asphalt events and joyrides.  I'm in Denver area also so my driving
includes lots of spin up the tires to 2X road speed on the ice then have them catch on the dry bits.
I run with Center/Rear locked on Steamboat/Ice stuff and that puts more load on the axles as
well.

If the stock Type 44 axles can handle that the S6 should handle the little old 300ft/lb of your
motor.  Now wheel bearings on the other hand... you are going to go through a few of those!

Cheers

Basically its a custom race clutch for the street that was concocted by Southbend with consultation from Dave Jones. For a hydraulic clutch its very heavy and Mr Jones specced it to hold 800 ft/lbs of torque. Nothing like the mechanical clutch on my Big Block Vette back in the day but stiff nonehteless. Its stiff but not grabby like a Spec. The turbo is at about 24 lbs of boost at 4500 rpm and full boost by 5000. The motor is making 300 ft/lbs at 4000 rpm.

We are taking a set of axles in to a shop to have them hardened and we'll install them this winter. The 6-speed CRB was rebuilt and I had everything hardened by Mr. Klugge in Germany before it was shipped to me.
