guys,
further to this i have used Terry's figures for ratios to work out some
ofthe various speed limits vs the revs in fourth gear for us people whose
speedo don't work propper:)
this is based off 3.90 with 195/50r15's
110kph 4,100rpm (110.208)
100kph 3,720rpm (99.993)
80kph 3,000rpm (80.64)
70kph 2,600rpm (69.888)
60kph 2,250rpm (60.48)
50kph 1,900rpm (51.072)
40kph 1,500rpm (40.32)
i know i'll remember these figures when i see a cop tailing my 510:)
hope this info helps someone other than just me!!!
SIMON
