Chain saw with forced induction

[mweba]

I'm sure this has been exhausted by the engineers already but would be interested to see them experiment with the BP-1 concept again. A balanced piston valve that expands the crank volume on the compression stroke and compresses the volume on ignition makes for vicious acceleration and power.

Well i am almost done with my mod ms250
it was a normal consumer clam shell and now it is a bit more

no turbo this time but i had a pipe hydro formed for it

started with .035 squish band
cut off the head and ported the saw
now its down to .015 squish band

im running 4 1/4-20 bolts as my mains and they run through the whole saw top to bottom
at the moment i am waiting on the head to come back

the head gasket is .016 copper coat and tape lol

anybody have any recommendation for fuel?

im thinking either 110 or 116 possibly
