i change gear at between 5k to 5.5k revs when im driving it hard, can u push further, and does pushing further actually gain u any more power, the engine changes tone past that and i worry about the health of the engine. replys from N/A owners/ previous owners would be preffered...cheers in advance!
no wonder you lost. 5-5.5 k? 
LOL These cars need to have the revs kept up to make the best of them! 
You want to change up at peak power, whatever that is. Peak power is 6600rpm, so thats when i change up. For example a Rev 1 tubby will run out of steam maybe at 6k, whereas a Rev3+ will keep going till 7k. Try experimenting (on a 1/4 mile track is possible) to see which gives you the most power. If your engine is healthy redlining it wont harm it (although try and not bounce it off the rev limiter!)....does the change in engine tone mean i shouldnt do this? it a gradual build up in tone then it drops to more of a straining sound which stays constant....bad sign? to be expected? also im due a cambelt change soon....so shud that matter? i phoned toyota and they said after the first change, come the next one if it hasnt gone it never will? so ive left it.Karl wrote:i have a 91 n/a and in an other post i was asked if i red lined the gears during a challenge i had and lost

It means its safe to rev to the redline (and a little beyond). Of course the tone of the engine will change but thats fine, don't worry about it. Its the kind of thing that you try not to do all the time, but driving to the redline (7Kish on a MK2 NA?) will be fine. Cambelt is more likely to snap if you labour the engine than rev it high. I wouldn't run it over its not worth the hassle if it does break.Lauren wrote:
It shoudl be done every 60K.
- the guy who did mine this week told me that it wouldnt do any serious harm to the engine if it did break - non-contact engine?- it sounds like it could be the induction kit doing this.? Barney wrote:when driving my N\A hard i notice engine tone change from 5/5.5k upwards
I notice that up at the 6k point the pull starts to drop off a bit.
Id make sure she is oiled up properly if your driving hard
My question is does this high rev gear changes strain the clutch
Rushing gear changes doesn't do the clutch any good, but there really is no reason to do this as the gains are not worthwhile. It puts more strain on the syncros if you rush it. The change in tone is the ACIS opening that gives you more power.'02 VX220 2.2 n/a Daily driver - Exige Size TD 1.2 - TAT shorty Diffuser - HardTop - Chris Tullet 4-1 Manifold.'97 mk1 Mazda Eunos Turbo track car with 260bhp/ton - soon more as Chris Wilsons going to build me an engine over the winter 
) ....xxxx yeh 
need to take the rpm past peak power point...so on the upshift you dont drop out the power band...think type r. 7100rpm should do it. My MIVEC kicks in at 5500 revs. peak power is around 7000-7500 revs. redline is at 8250. if i change at 7500 revs, next gear revs in at 4000 which means it is out of MIVEC and bloody slow. If i change at 8250, next gear comes in at 5500 revs, which gives me a tad more power. pizza boy wrote:with certain cars there is a
