How fast is your car going when you're doing 4000rpm in 5th gear.

As goes without saying, this would be when you're on a private road, obviously... :D

do i fall into that category dan? he he altho mine been off the road so long i cant remember now! think at 3000rpm was around 70 or just under!

I believe you do - a 4 door P1! What's that then??

You got the lump in it?? She back on the road yet??

I was just asking cos I was thinking more and more about that gearbox and running gear from the same car you got your engine from.

Well, guess what I've just bought from our friend Dal :)

He's already sold the rear diff, so he's gotta source another one, so it's a few more pennies. Getting it fitted at the end of September - taking him the car on pay day :D :D :D

Thanks for the tip of the P1 gearbox mod :)

Just been out for a drive. Mine's doing 70 at about 2800 in 5th, so it's not too bad only being a couple of hundred revs higher.

I can live with that for all the extra acceleration :D

This may help :-

Tyre size: 215/45x17 @ 8000rpm will be

1st 41mph Approx 5mph/1000rpm
2nd 69mph 9mph/1000rpm
3rd 99mph 12mph/1000rpm
4th 133mph 17mph/1000rpm
5th 175mph 22mph/1000rpm

About 90 as I picked up a speeding ticket for 92mph the first week whilst running it at 4k max and trying to keep up with a friend in a TVR on the motorway who was supposed to be showing me the way somewhere :grr. The most annoying thing was it was done by laser and his stealthy tvr in front which was doing well over 100 most of the time wasn't picked up.
