Its putting out some tidy power that mate, i already have 2 C18XE's, one high mileage standard which i am thinking about maybe stripping and re-building with a supercharger over a long period of time. And the other i have in the garage with no top end on atm, 38k miles from new, doing quite alot to it and hoping for about 170+bhp. Gotta love the C18XE's :-)
