I'll be taking the V12 to the Texas Mile in March. Place your bets on what it'll run.

5090 lbs with driver.
2.65 gears now with Quaife torsen style diff.
5 speed auto.
Wheel dyno and 1/4 time slip attached.

If I get the opportunity to make multiple runs each day I'll let it shift itself at 5800 then start short shifting to see if it picks up. I'm still pretty sure running it out to 58 is a waste of time. Where would you shift it?

This thing is a monster that comes alive at speeds most cars struggle through. It just doesn't stop pulling.

I'll be happy with 160 - 170 mph, depending upon atmospherics.

My wild guess is 29.6 @ 172.
