no, purely road use, normal road tyres.

9.85 @ 145mph
202mph standing mile
speed didn't kill me, but taxation probably will

Not to poo poo your R&R Colin.

But what’s the point..? I don't just don't your question really.

You can now get a Minispares gear kit for about £250.

You've just spent nearly that on a Kad Pinion support.

I my eyes it’s not worth the bother finding out. A man with your skills could build a box with your eyes shut.

I know yours is a road car ( noise can be a pain ) but just save yourself the hassle or smashing stuff up just for fun. With all those revs of a K engine and turbo its not going to be quieter anyway.

Are we not all after more time driving our cars than rebuilding them?

Si

P.S. Please don’t take my comment the wrong way.

I drill holes in everything..!

Straight cut gears is not a problem on a road car. Just use helical drops.

I'm sure I did near 80k over the couple of years I used mine as a daily drvier back in the 90's with SC gears.
You end up spending half the time in 4th anyway, so its just as quiet as a normal setup.

So when some joey comes on here about how his 16v turbo vauxhall is great compared to ours, he can be given the 'bird'...

Exactly the same as a standard car.

Gears make no noise when there is no loadings on them.

I have the 24 teeth drops with timkin idler and I can't say it's that loud at all. When your just setting off in first with a 3.1 FD it's quite noticable as you are really loading up the gears (in a car park people that are walking past suddenly turn around and stare, haha silly people...) 4th is OK on constant throttle, infact today on the way home from work the road noise was drowning out the drops.

But with that said I can see why people try to avoid using straight cut gears, I would rather listen to the exhaust and turbo boosting than gears TBH.
