Well, put it this way, D4nny8oy on here has a CVH engine that we built. Low comp, standard rebuilt head, Newman Cam, Stage 2 T3 Turbo and I consider that to be absolutely as far as that setup could go powerwise at 215bhp. That has been mapped extremely well on EFi and is one of the fastest RST's I have driven (obviously bar mine and Tony's), suggesting to me that I have driven alot of cars that 'claim' power, but very actually have it!
Danny's power is now restricted by his exhaust housing, in my opinion and I would be amazed if anyone could get any more power out of his spec.
I also believe that a proper 200bhp simply is not possible on a standard T3 turbo with 1600cc's. When I say 200bhp, I mean 200bhp on the same rollers as I made 350bhp.
