I own a P1 and it needs it cam belt changed, so I thought at the same time change my front crank pulley for a lightened one, but I've heard so many conflicting stories. Any advice, should I go for it or not?
Also my last scoob had a Hks SSQ dv which I loved, but can't face the outlay again, the sound was the bollox, but the Forge Dv is much cheaper, but is there any compare in sound, or does it sound like a VTA dv on a ford?

Cheers

I run Go Faster Bits lightened pulleys on both wagons. These are under driven and available from Rich Wild at Jap Innovations. May also be available from Scoobymania. Main pulley = 2.5kg. My replacement was 400grams. my total weight saving was from 3.025 kg to .635kg. ie 2.39kg. Expensive however.
Roger Clark Motorsport also do alloy pulleys but they are not under driven. They may do a crank pulley on its own.

The Perrin crank pulley is very (very) popular in the US, this is a std size pulley and costs about $125.

Does replacing the pulley with a lightweight one not have any effect on the crankshaft? I always thought that the heavy pulleys acted as vibration dampers.
