I am building a new engine for my TVR Vixen. Power will be in the 240-260bhp range and torque around 300nm. There are very few if any stock clutches for the Daimler 250 V8 saloon that will handle this sort of power. I am buying a lightened flywheel and can have this drilled to any clutch spec, but how do I choose the correct clutch?

Take specialist advice. Craig at SF Technic is extremely helpful - they do mostly competition stuff but also offer organic for more road biased applications.

Try Helix also. They will make you a hybrid plate up if required.

The key to finding the correct clutch is knowing the spline pattern on the gearbox input shaft, you can then search other vehicles for uprated clutch plates with the same pattern.
I spoke to a helpful guy at Demon Tweeks many years ago, put together a kit for me using a plate from one vehicle and cover from another - think it was a Helix clutch too.

The input shaft is 1" 23 spline. I am hoping to find a clutch from a car that will be supported parts-wise in 10-20 years time.

If you go for a standard sized 8.5" diameter from a pinto, I think they'll be available for the next 20 years. Everyone uses them. |
