"As for 180hp from an A-series on Webers, Im yet to see one. [I guess its not impossible] It would need some very serious money thrown at it. "
Maybe I should be a bit clearer, I mean 180 RWHP. It would be no walk in the park to get those figures out of an A-Series.
At the end of the day it is the results on the track that do it for me. Its not just the power output of the engine that determines the lap times and 1/4 run times.
