Thanks Thierry, that was my thought too, but it would also need to be remapped, and as Morgan have, in their wisdom, locked the ECU, it would mean a new ECU plus remapping, so could cost another £1500, plus the cams and fitting plus the exhaust system, which won't be cheap, judging by their quote to me for a new silencer box. So, all in all, prohibitively expensive.

As a matter of interest, I did a rolling road power run recently, and it showed a peak torque of 168.7 lbs/ft at 6041 revs, a long way short of the 220 Nm, but interestingly peak power was 220.8 bhp at 7576rpm. But as we suspected there is a hole in the graph between 2750 - 3750, when it starts climbing again.
