As for how much power the Variomatic can handle I'm currently finding out with my 66, it's the Gordini engined one that was turbocharged in 2021.
It is now normally aspirated again, ported Gordini head, 1690cc based on a B14, Emerald engine management and independent throttle bodies.
It's about 130hp at 6000 rpm and I'm experimenting with a nitrous oxide kit on it this year.

How do you get on with the propshaft and clutch ? This was a problem even with the standard engine. I always wanted to use a manual clutch with a CVT !

I've seen a few videos of your 66 - very impressive!

cheers

Beautiful! I bet that's a proper pocket rocket, are you going to retro rides at Goodwood with it?

Thank you, it's my pride and joy.
The drivetrain is all standard spec, new belts from the DOC, new standard clutch kit fitted. The clutch has stood up to all of the abuse I've thrown at it including a special launch mode I have that allows the engine to rev higher before engaging the centrifugal clutch.
I'm most concerned for the propshaft, but so far so good. I now have everything set up to only use high power at high revs, I can control the Variomatic through the engine ecu and an electric vacuum system to hold the engine revs really high while accelerating flat out, the reasoning being that the faster the propshaft is spinning the higher the power it can handle.
The belts have slipped occasionally, but only for a second or two before gripping, mostly with the turbo set up which had a lot of low end torque and before I was using the latest Vario control to keep the revs up.
