Just run on a RR and have 149BHP at 6130rpm at wheels.

Setup is 2l silvertop Zetec, 90mm trumpets, Jenvey 45mm throttle bodies, blue injectors, Kent sport cams, Scholar gass flowed head, St/St 4:1 to Technocraft can. MBE ECU 3D mapped by SBD. Soft limit at 7100rpm, hard limit at 7250rpm. I believe this should be running 200~210BHP at the flywheel, if this assumption is correct I am losing the best part of 40BHP and can't see where.

Checks so far: fuel supply ok, new filter, rail pressure tested ok. Compression test all 187psi+/-3, new plugs, new HT leads. Plug colour looks fine so no sign of one cylinder down (I thought it might be an injector). Valve timing was slightly out (3 and 4 degrees) so vernier pulleys fitted and now spot on but now the engine hits a brick wall at 6500rpm (under WOT acc'n). There does seem to be alot of electrical noise (picked up by the lambda sensor on the RR and on the MBE data logger). Ign timing not checked with a strobe but appears correct on data logger.

Can anyone point me in the right direction of my lost horses, or in the direction of a Zetec guru I can visit in the Dorset region.

Thanks

John
