Proper shift point / powerband for racing?

*sigh*

The fast and furious series has gotten everyone saying "double clutch" this and that and they don't have a damn clue what that even means. I guess it's a peeve of mine to see the term used as relates to anything but large trucks or blown synchro's or race vehicles or something.

Or if you're trying not to abuse your synchro's on a downshift. If you skip shift on an AP1 s2000, it's smarter to make sure everything is spinning the same speed before you go into gear. The 2nd and 3rd gear synchros go out with 20-30k miles of failing to rev match while skip shifting.


A lot of people overuse it, but it's actually a pretty common/useful thing to do.

Since torque is flat from about 2500RPM to redline, you really want to drop as low as possible assuming you will stay in gear longer than the next shift - at 70MPH you will be about 5300RPM in 3rd and can run up to about 95MPH before shifting (about 4.5 seconds), so definitely the right choice if you have the traction. (I'll assume you can shift faster than 4.5 seconds with the 6MT .)

Hmmm - need to figure out how to convert torque in gears to acceleration to compute time to estimate the difference more accurately.

I really need to post my Torque in Gears spreadsheets!

I raced a GTI tonight in 5th gear from 30mph and he walked me, he probably had a chip.
