What is your favorite combo.
I need to stay in the 4500-6500rpm powerband. I can tach out at 7-7300rpm on the limiter. I have a spare trans I can build up now and then install... whenever. KT |

yes - of course. but we were talking about shift points, and the example in question was 6500 rpm. i agree not all the posts were totally nonambiguous, but there's a limit to how much i'm willing to recap prior posts in each new post :-) so - for completeness - we are talking about the optimal shift point for low ET... i believe this implies we're talking about higher, rather than lower, rev ranges... the lightened flywheel effect does two things (trying to stack a couple of responses here...) one is improve the "engine braking" effect when off throttle. the other is to make sure that the engine has fully dropped to the revs it's going to be at when you upshift. in our 2->3 *high rpm* example, if you can shift faster than the time it takes for the engine to coast down ~2500 rpm, letting out the clutch will drag the engine down and unsettle the driveline. it also makes shifts smoother if all the rpms are matched nicely |
