What do you mean by "any other bits"? There are lots of bits when it comes to supercharging a 928.

You might want to consider a supercharger on that list.

All ready bought stage 2 supercharger. Thinking about cams and headers .

Headers/exhuast with bigger diameter possibly make sense but cams? Most who bolt on these things seem to do ok with stock 928 cams and whereas I am sure cam profiles can be optimised for supercharging I suspect the benefits are comparitively marginal. However if you have the $$$'s burning a hole in your pocket try talking to Colin [Lizard] about a set of his cams and whether he has a profile well suited to supercharging [I seem to remember someone has done this].

Funny cams were mentioned. I spoke to Victor yesterday and he put a set of Colin's cams and a stage 1 kit on a car for a customer. Said once it was tuned for the supercharger/cam combo it was a beast.

I just found this thread Peter.

I just replied to your email.

Regarding a windage tray. I would not recommend putting one on without increasing the big end clearance.

What I recommend is to rebuild the engine and install the SC AND THEN see if you really want the extra HP.
