Thanks


1900rpm@100km/h is about right for a 4 speed auto and 3.08:1 diff gears with 215/60/16 rubber

If you have shorter diff gears and smaller tyres then is should be around the 2100rpm mark

Lol, I love how all our Sixes are sitting around 2000RPM at 100Kph, and my dads little pulsar is at just over 3000RPM at 100Kph
(he has an older car than I do, and he hates that)

1900rpm@100km/h is about right for a 4 speed auto and 3.08:1 diff gears with 215/60/16 rubber

If you have shorter diff gears and smaller tyres then is should be around the 2100rpm mark


my car does 1750-1800 with 3.08 and auto (with 235,40,18) and did around 1800 or just over with stock 15in rubber :S
