How is it being done? Timing? Starting out with minus numbers? Boost control? What else?
We hear that the COPOs don't use drive by wire. Do the others?

I'm thinking this thread might belong one floor down, if we get actual tech oriented answers.
Not sure we will. It might take membership in the Six Figures Club to find out ;-)

Markie - Did you really think any of us were going to just spit out our secrets??? I'm not so sure that even joining the Six Figure Club will help you .......But I will tell you I don't use DBW in my COPO's.

Jacko, No. Actually I didn't...and so far we're still okay in this section. ;-)

I have seen data logs from a Ultra Street NOS car that is around the same weight, that was pulling over 2.2 G's on a 275 DR. If these new tires are lets say 255 I would think a min of 1.95 G's. So just a WAG for the 632.

60 Foot ET = 1.2241
330 Foot ET = 3.4843
1/8 Mile ET = 5.4284
1/8 Mile MPH = 126.1316
1000 Foot ET = 7.1115
1/4 Mile ET = 8.5372
1/4 Mile MPH = 158.1890
