Well, yes it is if you've put it on the 998. It's a custom ignition designed for a different engine and cam. The bob weights and springs (and possibly vacuum advance but I doubt you'll have one) are the ignition map for the engine.

I know that people think that distributors are crappy old technology but they're actually quite complicated and advanced devices which are capable of proper 3d ignition timing if they're setup right. You need to use a dizzy which is designed to work with your camshaft. And if you don't have a vacuum advance on a road car and in this weather than you'll suffer anyway.

It's not going to give you better performance on it's own, only when it's working how it was designed to. It'd be like putting the map from one car into the ECU of another car without any research and just hoping that it would be right for the car.

Yea, I had thought the curve would of been set up for the 1425, but thought I'd give it a go.

I'll stick the lovely Cosworth back on the 1425 then... :sad:

Back to points for me then... *sniff*

Just out of interest, do you know what the Cosworth ignition does?
