3hp briggs and stratton engine help?

[Hex429]

hie i have a 3hp briggs and stratton horizontal pump engine. i want to get some serious rpm and power out of it. i am thinking about forced induction, making a fan force cool air in the carburetor, lightenning the flywheel and custom air box.

this is only what i can afford and i want to put it on a very lightweight aluminium go kart frame

Dont lighten the stock flywheel. Thats a HUGE no no.

Get a lighter flywheel off of an equivalently sized vertical shaft Briggs powered push mower. Very common.
