Went to dyno today.
First run made max power of 111 bhp.
Second run with new plugs, took off dizzy and upped rev limited, made 116
Third run, adjusted cam timing which was a bit out. Both cams needed tweaking, had a quick run up to 7k rpm. Was going to do another run to record power 500 rpm per time and the car started misfiring heavily under full load. Checked cam timing, fine, checked dizzy temperary mod- fine, car misfires heavily under any load now. Had to leave it at the rollers. Would rev up fine at say 25% throttle but any more and would say that it sounded like it was hitting a rev limiter. Checked fuel pressure. That's fine.
We called matt Humpris who suggested it could be the throttle body or lambda sensor. I think I have spares but the rollers are 65 miles from the house.
Lucky had a lift back with my mate as he took his mk1 escort down same time. He got 188 bhp lucky git- goes really well
Any ideas peeps
