Mine is the full 2297cc engine - not the Misubishi effort found in W203`s nowadays.
Having a clutch on seemed a bit weird to me,i thought the main advantage of superchargers was immediate oomph from idle,not at nearly 2000 rpm....

A fine example of a GTG experiment I remember demonstrating this at Kettering.

When the car is stationary and in neutral, with the bonnet open, just push the gas pedal and at the magic rpm the clutch engages with a tiny click and the supercharger starts to whine.

Anyone with a k' model should try this, if only because it sounds awesome

i am by no means a rude person, the post was a perfectly honnest request for advise, to which i felt shude's reply was a little agressive.

the reason for my enquiry is that, there is may have been an option to change the s/c pulley rather than the crank pulley, thus removing the clutch on the s/c, along with chipping and mapped on r/r, would deliver an extra 40/50bhp, and along with a free flow manifold would add an extra 10bhp, all for a relatively low cost.

so i would liked to have known what the make and model of the s/c was.

I thought I softened the supposed aggression with a

Hi esox,

Glad to hear that, sounds as though you have done a thorough check!

AFAIK the reason for the clutch on the earlier models is to reduce unnecessary wear on the S/C when idling, for example, when in traffic. There is still very little lag on these engines IMO as pretty much from take-off the S/C will be spinning, unlike a turbo which is waiting to spin up from exhaust gasses.

Other than the possible performance differences, does anybody know of any other reasons why this change was made (eg clutch problems etc?)

Graham - maybe they could have fixed your ECU fault in the end by changing the pulley on the S/C, bit late now mind...

Cheers

Will
