How close to the red line do you normally get?

OT.

Gibbo,

Are you interested in the trackday when the calendar is out?

You should be gearchanging (on a track) so that the revs drop to around the peak torque area, as this is where max acceleration happens... on a road, doing this, you are just wasting fuel unless its for an overtake...

I'm pretty sure you want to change up when current engine torque * current gear ratio = engine torque when changed up * next gear ratio. This is the 'perfect' shift point. Even better interpreted as when torque to the wheels in the current gear = torque to the wheels in the next gear.

Don't usually go above 7,500 rpm, it pretty much sounds like all hell is breaking loose at that speed so I change gear.

Dash starts flashing at 9,000rpm. I change shortly after that

That's the spirit.

I miss do the rpm sometimes. :cool:

Not sure where my limiter is set but it's getting moved today.

6500 by default

Most the time its around 4K to 5K which is fine in most circumstances. If I am pushing on I use the full range so change up around 8K. The redline is 8200 and I have hit the limiter twice in 10,000 miles, which is something I try to avoid. Its about using the car to be effective not to rev the nuts off it and on the road its doing silly speeds in seconds so running it high in the rev range in anything over 3rd is likely to see me in the papers!

A big lump of my power comes in a 4.5k, however this comes along with a snarl from the exhaust and quite a loud induction noise right up to the redline, so when in town i usually keep it under 3k, when i'm going for it down my fav back roads the revs never drop under 4.5k and since the car pulls strong right up to the 7k redline i'm usually someplace between the two.

Shoei · 12 Jan 2007 at 11:34

car, keep it sensible, around 4k tops.
The NC30 is another matter, redline at 14,500rpm.
Change as close to it as possible in 2nd, 3rd and 4th.
In first i can hit 60mph just before i get to redline.
The noise from the race can is spine tingling at high revs.

I rarely bother going above 5000rpm. I've got enough torque to outdrag most cars without having to rev the engine.

Bikes different. That needs to rev. Had it up to 16,000rpm

When i'm hammering it I rev it about 250rpm short of the limiter, drops better into the powerband in the next gear i've found through trial and error.
