There is an article in the new Walneck's Classic Cycle about Britech and it's owner Jaye Strait. In the article, there is mention of "crankcase breather modification alone adds 5 hp at the rear wheels".
I am guessing that a piston traveling up & down must alternately need to suck & displace air and that air must offer some degree of resistance.
But is 5 hp really laying around there??
Anybody know about this?
Best Regards,
Dave
