daverclasper Posted September 23, 2020 Report Share Posted September 23, 2020 Hi. Well this is what I have with 155/80 tyres, so not ideal, though stuck with it for now. Just wondering what is the best way to drive this car, reg fuel economy and more importantly to me, engine/gearbox/diff wear, as I guess this can labour the car?. I tend to drive mostly with low revs through the gears (live in a city). Would it be better to give it a bit more beans?. Car maybe a bit sluggish to what it should be (never driven another), though seems to cope with motorway inclines in OD top ok. Cheers, Dave Link to comment Share on other sites More sharing options...
Pete Lewis Posted September 23, 2020 Report Share Posted September 23, 2020 Dave drive it like you stole it ............!!! labouring is stressful free reving is less harmful its all down to what you are happy with Pete Link to comment Share on other sites More sharing options...
johny Posted September 23, 2020 Report Share Posted September 23, 2020 Well the gearbox, being the weakest link on these cars, has a much easier life when in 4th so the more time you can drive like this the longer the box will last.... Link to comment Share on other sites More sharing options...
Nigel Clark Posted September 23, 2020 Report Share Posted September 23, 2020 I would expect a 3.27 diff is a bit high for a 2 litre engine pulling the weight of the Vitesse. 1st gear getaway will be slower with the higher final drive. That said, I've never driven a Vitesse 2 litre which didn't have a 3.89 diff. On the move, the high final drive ratio shouldn't be a problem, it's only that acceleration from standstill will be a bit sluggish. If you can live with being a little slow off the line, the benefit of the 3.27 diff will be very relaxed cruising. Let the engine rev freely when you can. The clutch will need to be slipped a bit getting off the line but even so, the friction plate should cope for many thousands of miles. Once on the move, engine, clutch and gearbox will be fine. Has the speedo been recalibrated for the non-standard diff ratio? Nigel Link to comment Share on other sites More sharing options...
Gully Posted September 24, 2020 Report Share Posted September 24, 2020 I found the 3.27 diff too tall on my GT6 and swapped it for a 3.63 (I have overdrive). Much nicer for pulling away. Hill starts with the 3.27 took a bit of work to balance over-revving and bogging down! Gully Link to comment Share on other sites More sharing options...
Clive Posted September 24, 2020 Report Share Posted September 24, 2020 I am not at all convinced low revs =good fuel economy. Mainly as more accelerator pedal is needed to pull away and increase speed. Better to have the engine developing stronger torque. First gear is tall on these cars, and in town at 30mph you won't be needing 4th. But fundamentally, if you are that concerned about economy and mechanical wear, you have bought the wrong car!

johny Posted September 24, 2020 Report Share Posted September 24, 2020 For town driving Dave I can really recommend the original 3.89 diff as it allows you to cruise around in 4th virtually the whole time. Mine pulls well from 1100rpm which is about 20mph and at 30mph everyone gets to enjoy the great six sound😍 Link to comment Share on other sites More sharing options...
