CastAway Guy Posted July 12, 2014 Share Posted July 12, 2014 Most people might think this is abit stupid but I am curious, the gear ratios are completely different to my previous car which I had for over 7 years. My question is, at what rpm do you change your gears when driving casually ? My second question is when cruising at about 30mph in a 30 zone ( call me sad but I don't want to kill a child ) what gear are you in ? I am unsure if I should be in 3rd or 4th. I don't want to over use 3rd but at the same time I don't want to put pressure on the engine by sitting in 4th with revs as low as 1.5k. When in 3rd and 30mph I'm at 2k rpm when I switch to 4th at 30mph I'm at 1.5k rpm Thanks 1 Quote Link to comment Share on other sites More sharing options...
quit Posted July 12, 2014 Share Posted July 12, 2014 30 @ 3rd I learnt on my speed awareness course Quote Link to comment Share on other sites More sharing options...
savage bulldogs Posted July 12, 2014 Share Posted July 12, 2014 Driving casually I normally change gear at about 2.5 k ,keeps me just off boost . In 30 limits the old uk 5 speed didn't like 4th . Since fitting a uk 6 speed gearbox 30 in 4th is about 1.7 k and feels better . Quote Link to comment Share on other sites More sharing options...
CastAway Guy Posted July 13, 2014 Author Share Posted July 13, 2014 So when casually driving, try to keep the rpm at about 2k ? 1.5 seems low and I can only assume it's making the engine work harder then it actually needs too ? Also try to keep rpm below 3k because this is when the boost is kicking in ? Thanks Quote Link to comment Share on other sites More sharing options...
savage bulldogs Posted July 13, 2014 Share Posted July 13, 2014 Mine will hit 1bar @ 3.2k although it will make boost before that if I'm heavy on the throttle . I do tend to use 4th for most town driving but, change down for inclines. even though my 6 speed is a uk version 1 to 4 are a much shorter ratio than my uk 5 speed (im still getting used to the switch) Tbo I'm probably not the best person to offer advice on economy and keeping of boost as I bought and modded my scooby to give me smiles per gallon rather than mpg Quote Link to comment Share on other sites More sharing options...
Gambit Posted July 13, 2014 Share Posted July 13, 2014 I can use 5th gear as long as the traffic stays at a constant flow, but do find I have to change gears more frequently. Quote Link to comment Share on other sites More sharing options...
