On a side note on the Awsome rollers my modded 106 GTi 120BHP standard got 130BHP at the wheels and 142BHP at the fly. It was the highest powered 106 of the day. This was with a induction kit, decat and full exhaust. I had a L/B fly wheel and 4-2-1 manifold fitted after that. personally I think the Fly hourse power may be a little high. I'm no expert though.
