K front pully in ali?

[DohNut]

I am sure that Folia-Tec would do you a Carbon /Titanium look sticker to cover up the existing pulley if it bothers you that much wink.gif

The imbalance of the front pulley is irrelevant because it is all at relatively small diameters and you can;t do anything about it. The only balancing that is worth doing with a K is crank (unit), flywheel (unit) and crank and flywheel (assembly) - according to my engine builder.

 

You shouldn't have too many problems with the alternator. You have the Rover spec alternator. You might find that a large pulley on the alternator alone is all it needs. Standard Supersports and SLRS rev to 7600-7800 without alternator problems, so just take the ratio of the pulley sizes and see if the safe 7800rpm turns into a safe 8200rpm. Sorted.

If your clutch is approaching the weight & diameter of your flywheel (which it does with any of the stock clutches and the lightweight flywheel) then it's plain to see that it's as important balance-wise as the flywheel.

 

No Nig, I wasn't suggesting that every time you remove the pulley you need to rebalance, merely pointing out that it's not a particularly savoury piece of engineering.

Think I'll just apply a lick of paint to it... wink.gif

 

Thanks all. It's interesting what you learn. Just when I think I know enough talk with confidence, I realise I only know enough to be dangerous. Ah well, at least I recognise that fact.

 

One day, maybe I'll go down the "ultimate K" route, but I doubt it given my current mode of operation (less racing and more touring).
