Calcs on speed from a 964 and a 915 transmission

Anyone have a fast and dirty way to calculate potential speeds or times 80-120+ mph on a stock 915 LSD equipped trans backed by a mildly tuned 964 engine? I am going out to Willow Springs and the last time, same ride but with a euro spec 3.0. 14 years ago, time flies whilst getting divorced, moving three times and retiring.....

Mildly=SW chip, headers, free flow cat, no muff and a free flow intake....

4th and 5th gears specifically.....I never used 5th with the 3.0 at Willow. I'm wondering if I will this time.

Thanks in advance.

Depending on your aero, and with enough room, I'd say 130-140 top speed

I think giving you calcs for 0-60 would be relatively easy, but 80-120 will be much harder because at that point aero will be a BIG part of the problem, and then there's gearing, and those, I think, will make the calcs much more difficult.
