Crank case breather

I've never heard of putting an intake cam on the exhaust side of a 14 before. What made you try that?


It is a familiar idea, my old Bonnie has an intake profile on the exhaust cam as they fitted a very tame exhaust cam to downtune the engine so it wouldn't kill the crank bearings.

Using intake profile on exhaust side is a common trick in turbo Volvos and turbo Hayabusas etc. More lift and duration to exhaust side.
And notice lobe centers.
You can compare this to Kent Cams "turbo cams" for 14.

T24  ..the system I'm using this time is the Finnish pro boost system. I could get one from BIG CC , but  to be honest it's never gonna see a track.so doesn't warrant 3 times the cost .its a street bike at the end of the day so nothing fancy or overly expensive. I've also got a 100hp nitrous kit off my old GSXR1100...So I'm gonna chuck that on aswell but knock the foggers down to 50hp.
As I guess you already know.the pro boost systems bolt on to a standard engine with heavy clutch springs.although I'm going for an MRE lock up clutch...probably realistically looking at 200 hp without gas..which is enough to put a grin on your face on a street bike
I,ll photo document fitting,  although its straight forward enough,and post for those guys who are interested
