shifting at higher revs, better than at lower revs ??

[96LSIntegraRocket]

I just read the turbo-kits.com faq section and they say " The load is actually harder on the engine at 2000 RPM 5th gear 30 MPH than at 6000 RPM 2nd gear 30 MPH " is this true??? i always used to shift at 3500 rpm no matter what then i thought it might be better to shift at 2500 rpm or slightly lower,...... any info or comments would be appreciated

hmm, I dunno... I shift a 6,000 or 7,000.

If i run 2nd (AUTO) into the ground I get 85 mph @ 7,200

if i ride it out normally my tans kick down cable will shift a 4,500 to 5,500 depending on how hard you are pressing the gas.

I do suggest you shift at least above 4,500 rpm that way when you drop into the next higher gear there will be less strain.

definately. ever realize that your car shakes and make evil noises when you go uphill in 4th at like 35mph? thats cos its bad.

my dad taught me when i was 14 and learning to drive a standard to shift at around 2500...so i did...then i realized...my dad drives like an old lady. so i shift quite a bit higher..like around 4-5k...usually.

what engine revs 6000 in 2nd at 30mph? i can go almost 60 in 2nd around 7-8k..

2000 civic Dx


1st 35 or so
2nd 67
3rd 103
4th ??? over 120 ... im not sure how much but i hit my govonor

and remember the civic dx only goes to 6800

i shift @ 5 grand in first every time 4grand in second and third and 3 to 4 grand in forth ... that is how i daily drive ... totally different in a race...

See thats what you guys get for letting a computer control your car... I used to have what is called a "FUEL CUT" which turns off the pump @ 6,200 rpm... I've long since disabled it and although the physical rev limit for my car is about 8,000 I keep it to 7,200, or on a flat road I may go to 7,500... I did some vlave train mods, you can check up on it at my web site...

Honda engines are build extremely well, people like to nag about honda and they like to say that it needs to rev high to get power. True or not I still think it's a good thing.

are you asking about transmission longgevity? i've never heard about the 5th at 2k v. 2nd at 6k thing. the only thing i know is shifting earlier, before vtec if you have it, will help gas milage a smidgen. were they specifically talking about honda cars or cars in general?

u guys are going a bit extreme on the shifting thing.. shifting around 3500 rpms would be good enough to not labour and stress your engine at too low rpms on too high a gear. revving high like that all the time will also put stress on your engine..

Are we talking about normally aspirated cars or forced? I think it would be different. I know for n/a, the lower you shift, the better. Gas mileage is better and there's less strain, as long as it's not so low that your engine is bogging. Guess it all depends on how you drive.

well..FI would be the same situation. the lower you shift the less gas you are going to use. the more rpms, the more gas is put into the cylanders. with a turbo the lower you rev the better chance of the turbo not spooling. mine doesnt spool til about 3500. so if i shift below that i get much better gas milage..but wheres the fun?

[CXHatchback]

Yeah, I remember doing that with my old 300z. The engine was going so I'd shift at like 2500 all the time to keep the boost to a minimum. That or I'd say screw it and beat the hell outof it.
