supra_24 Posted April 11, 2014 Share Posted April 11, 2014 Hey guys, Maybe another silly question from me, but I love my cars to bits. I was out an about today giving the S15 a bit of a run and I shifted a few times from 1st to 2nd at 5000rpm or just over. Is this a resonable rpm to change in 1st, if your giving it the beans and can the cars engine take it? (I assume these engines can handle these high rpm's in low gears) Would this also be a reasonable rpm to shift from 1st to 2nd in a supra, if your looking to get up to speed quickly? Or what do you guys shift at when you race about? Any advice would be appreciated. Im a bit of a worrier when it comes to my cars lol Thanks again guys.

Gaz6002 Posted April 11, 2014 Share Posted April 11, 2014 It's Easter holidays again isn't it? Anywho, I'd be changing gear when it feels right. Don't worry about hurting it, Toyotas are built pretty tough Quote Link to comment Share on other sites More sharing options...
Havard Posted April 11, 2014 Share Posted April 11, 2014 If you go over 4K all kinds of funny things happen, they start going all over the place and become difficult to control. I think this is the car telling you to behave. I never go over 4K revs, no matter what gear I am in. H. Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted April 11, 2014 Share Posted April 11, 2014 You should change gear when trying for maximum performance at a point that puts the engine at the best RPM in the next gear higher to maximize the torque band available in that higher gear. In a road car this means compromise as the gear ratios are designed for maximum performance and will have a less than optimal spread. My late mother, even in her seventies would consider changing up at 5000 RPM to be driving economically and carefully And it's "changing gear" not shifting.

Abz Posted April 11, 2014 Share Posted April 11, 2014 I generally change gear at 10k RPM, depends how the car feels on the day, after all they have feelings right As Gaz says, they are pretty tough, so keep an eye on the needles Quote Link to comment Share on other sites More sharing options...
