What car apart from a diesel reaches peak torque at 1.5k RPM you dick
Did I say 1.5krpm? No I said 2-3kRPM  
You quoted me saying to change just after peak torque so if you put 2-3k RPM i'm assuming that peak torque would be 1.5k rpm. As I said change just after
So please wind your neck in and read what you post

steve is right. although the argument is pointless as it depends on the engine. for example, look at this graph:
thats my x16xe on tb's. best gear change will happen at 7400rpm so well after peak torque.

well 90% of the torque is available at 2000rpm in my 328, as a comparision my bike makes peak torque at 10,000rpm but peak power at about 13,000. Now I know exactly where to change gear to make the bike go fastest and its not at 10K.....
its not at 2, 3, 4 or 5K in the BMW either.....

if i changed just after peak torque(6300 rpm) then I would be too far down the rev range in the next gear to make use of the rise in bhp at 5000 rpm and only using 130 bhp.

That is correct it is pointless as I said all along it depends on the engine.
Your car develops much more BHP than Torque so yes it would be right to change high up the rev range.

Doesn't matter what I said because at the end of the day:
- You're a muppet
- Everyone knows you don't change after peak torque

How can I prove? Just look at anyone that races at anywhere....they take it high up in the rev range before changing.
Do you see people at Santa Pod changing at "1.5krpm" ? Erm no.

No you don't see people at the Pod doing that because as I said
IT DEPENDS ON THE CAR
me and steve had a quite sensible debate that has been ruined by some 12yrs old who knows nothing but wants to post "your a muppet"
FFS get a life if you can't join in the discussion then fook off

The only person that is making some real sense, he has hit the nail on the head, if youchange to early you will be out of the power band in the next gear, listen to this guy

In my old vectra, going by your theory i d have to change at 3,400rpm to get best perfromance!
Doesnt make alot of sense that mate, cos your going to want to change at peak power(bhp) and that for me was at 6,400rpm.
The engine wouldnt even show its ability till you take it past the 4,000rpm. That kinda proves ur theory wrong there doesnt it...

Why do you keep changing what you say about optimum shifting time mate?

i used to change gear when the CAR felt like it wasnt accelerating anymore, NOT when the rev counter told me to. its all about knowing YOUR car, not doing what people told you to do.
Incidentally, my car used to stop pulling at fairly high revs, probably about 6900-7000 revs, peak power, not peak torque

I don't as I said
IT DEPENDS ON THE FUCKIN ENGINE
as a rough guide on a standard n/a engine changing just after peak torque is what i'd do.
When I had my 16v SRI peak torque was 4k RPM so i'd change at 5k

why would i change that low?! you dont really know what ur on about do you? the revs would drop too low and out the power band if i changed at 5,000 rpm!! Why change gear before you engine hits its top potential/power?
Plus by holding the power till peak power your stretching the gears and getting the most out of them! id change at 30 at 6400 but at 5000 id be changing at a slower speed!

3 things
1. stop arguing with rcb, its pointless and not constructive
2. i wasnt aiming the comment at you, i was trying to tell gary my opinion, i dont care about the arguing which has developed
3. Vtec. try changing at peak torque in a honda and then see the 0-60 times get dramatically longer

Just the way I drove it was more than quick enough driving it thst way it was only a corsa SRI not a race car. Just how I drove each to there own.
That is my opinion as I said I could be wrong.

When you were doing some 'spirited' driving what RPM did you change at in the SRI then?
