Hi,

My other high-performance cars (Ruf and M5) recommend not to exceed 3,500-4,000 RPM until the engine warms up a bit. In fact the M5 has color-coded bar-lights to remind me of the shift points depending on engine tempertaure.

Regarding the Cayman I read the manual and searched this site and found no information on rev limitations and engine temp. The Cayman engine warms quickly, and by the time I cover the 0.6 miles to the freeway on-ramp, the engine temp. is already up a bit. However, that may not be the case on very cold winter mornings. I am curious as I have an uphill on-ramp so I need higher revs to merge safely.

Here's my question: Is is ok to rev the engine past 5,500 RPM on cold start? How do you folks drive when engine is cold?

Thanks for the education.
