let explain the situation

the engine was already on a westfield bought from UK,the engine had a problem

so we strip it pieces,the engine spec was not good for road use as the cams was too wild,the carbs too big....

we rebored the block,change pistons and rods,new engine bearings,new multilayer head gasket, and new fast road cams from newman.

after this the engine was back on the customer car and he did with it the running in for about 1000km

by the time the customer was after more power and more usable engine so he asked for a Turbo YB engine.

the engine setting with these cams and new cr (compression ratio) was never done for after 5500rpm to 8000 rpm as it was in running in

when the German (turbo965) customer bought it he asked me to remove the dry sump system and i put a normal wet pump,he also told me that he will fit smaller carbs.

as he was on dyno with the engine....why dont stop pushing if you see with the wide band that fueling is lean and with knock sensor there is detonation
