4.08 Gears @ VIR and CMP?

Mike

CMP it would be great with. VIR has 140+ mph straights though. The time to make the extra shift up a gear might negate any gains. I know at Daytona on the banking watching my harrys lap videos, I was losing 3-4 mph on the 5-6 shift.

Yea this was my concern about VIR. I've only ever tracked it in my LS1 FD RX7. Which while it had 4.10s as the FD, the trans gear ratios are much longer on the t56. So winding 4th out on the straights is all you needed to do. I digress...

Let me throw the following at you and get your input: Like you said VIR has a couple of long 140+ straights. The theoretical shift point at redline for the stock gears, running a 305/30r19|26.2" diam. tire in the back, is 125mph. Whereas with the 4.08s it's 113mph. Either way you are going to see a upshift somewhere in there. That earlier shift to 5ths 1:1 ratio would cost me some mphs by the end of the straight, correct? Which obviously is unfavorable. However, would there be any gains in the rest of the course? Also, would the loss in speed at the end of the straight, in theory, allow me to brake a little later. offsetting some of the loss in time on the straight. I only have a few track days under my belt so I am still green overall and 100% newb in the 370z. So forgive me if that last question is completely absurd.
