Maximum power reached

bonzo · 17th September 2007, 21:00

Could someone please tell me at what revs is the maximum power reached on a type r.
I am trying to maximise the acceleration and have hit the limiter a few times,,so at what revs is it ideal to change up at for the best performance?

Hello mate,

When VTEC...ing I change up at 7800rpm as thats when the engine is pushing out max bhp, although it does sound rather nice from 7800 to 8300rpm

You want to change just after max power. You will still get plenty of good power, and this is a better place to be than changing up and getting much reduced power (lower revs and disadvantageous gearing). In reality, just before the rev limiter.

At what revs does the limiter cut in ??

OK Mr cleverclogs,,,I thought this forum was for asking questions and receiving answers,,,maybe i'm wrong (in your case).
If you think it's a daft question, simple, don't reply to the post, end of.

That wasn't meant to come across as it did Bonzo! I don't know the answer (obviously) just keep revving in gear until the revs no longer rise and hold steady, thats how you know the limiter has kicked in.

For maximum acceleration change gear quickly (i.e. dump the clutch) at about 8,100 rpm so that when the clutch re-bites, it hits the peak bhp about 7,800 rpm.You'll probably wheelspin abit in 1st & 2nd though and I hold no responsibily if something goes bang or breaks during this process

Anybody know the optimum revs to change gear in the 2.2 cdti for maximum acceleration

, as the above only really suits a petrol engine

he he, I keep getting it. It hurts

Many thanks for that, this is my first diesel and a bit different from my previous DOHC petrol engine(s)

Thanks czechplastik an interesting post.....
The spec sheet for from honda say max output (140PS) at 4000rpm...
I have normaly driven upto this point then changed, but sometimes find it takes a little time for the turbo to kick back in. I may just have to try your rpm listed in the morning

Sorry I actually posted the wrong one, that was for a chipped diesel.

Correct one up now!

All credit to Pottsy btw!

Thanks,,,,,,,,,,,Rant over!!!!

i think its actually 8250rpm

redlining puts a lot of stress on the engine. not recommended imo
