Yes it seems good at converting fuel to noise!
I did see a +8 at Beaverbrook last year with a JE 4.6 and SSL suspension, but it had alloys which I really dont like, and it sold by the time I sold my Caterham.
I've always wanted a supercharged car and now I have one.
I've been on with the machine polisher the last few nights as it was well below my standards, but its a great foundation and will make an amazing car once I have tweeked it a bit!
