High Pitch sound when accelerating

[simonthepostman]

Hi -
I just got my 1st Caterham 7 - 1.6

All well except when I accelerate there is a high pitch sound. It's really only when I accelerate.

Any ideas ?

Passenger screaming?

What sort of sound? From the front or the back?

Alternator belt slipping perhaps - check the tension of it.

Diff?

The 1.6 sigma I drove was terrible
