Top speed per gear

[green02crew]

Does anyone know the top speed in each gear for the manual on the 5bw? I can’t find it listed online and my local streets don’t allow me to find out myself.
What rpm is ideal for a roll race start?

I'll help a little on the gearing, theoretically, using this equation:
MPH = (RPM * Tire diameter in inches) / (Gear ratio * Final drive ratio * 336)

Assuming:
- 6500 RPM redline
- 26.3" tire diameter
- Wikipedia gear ratios from Tremec TR-6060 transmission - Wikipedia
- Final drive ratio of 3.73:1

The top speeds in each gear at 6500 RPM are:
1: 59 mph
2: 84 mph
3: 112 mph
4: 146 mph
5: 166 mph
6: 252 mph (which obviously is power/aero limited)

I wrote a gear ratio calculator, here are the numbers for the M6 and the A10.

I found another source for the gear ratios - I think the wiki ratios and calculated speeds in my post are correct.

In his ICON review, Jason Cammisa from Haggerty reported redlines of 58mph in first, 83mph in second and 113mph in third. Link: ICON review

Huh. Not sure where I got the other numbers from. But yeah, cadillac.com is probably trust worthy. I've updated my page...

Thanks all!
What rpm/speed do you guys decide 3rd instead of 2nd for a roll?
