just out of curiosity (and for the sake of not grenading the engine on any downshifts), does anyone know the top speeds in each gear for a c4s 997.1 stick?

 

I just Go by RPM Sweet Spot is around 6.5K - 7.5K RPM You Get Max HP on each gear

 

41, 69, 100, 125, 148, 182.....watch the the 5-2 shift (going for 4th/ooops!)as it is the killer, but you know that. The tranny will usually keep you out of accidentally finding 4-1= aaaargh! but it can be done. I try to go down one at a time but 6-4 is generally safe and 5-3 slightly less so. Ratios are pretty close up there.

 

This matches my observation through 4th gear. Never maxed out 5th or 6th gears though.

Have fun confirming for yourself!

 

I remember years ago when the VWs from the 1960s had tick marks on the speedometer. They indicated tha maximum speed for each gear. I am sure they save a lot of $$$ by doing this and eliminating a tach. These marks let you know if it was safe to downshift into third or second gear, in this case a bit more useful than a tach. Such marks would would be helpful in the 997 except I can't see the analog speedometer. For the driving I do, I just need to remember that downshifting into 2nd is OK as long as I am below 70 mph. I really have no problems getting the right gear.

 

I drive a c2 and found that when on the street cruising in 3rd at 4k RPMs downshifting into 2nd lands me in the sweet spot of 2nd gear giving me one he'll of a boost!!

4k is my downshift point
