Nitro engine tweaking and hopups...
So I started with an old worn out force.28 then I dropped a hobao Mach.28 6 port into my lx2 coupled with the ofna pro tuned pipe and a pro header. I'm seeing improvement already, but like any guy, I'm on the never ending search for more power. So do the make improved button heads for engines? If so are they worth it? Also what can I do to my carb? Is there things I can do to improve the existing carb? Also I've seen "boost bottles" and from what I've read, they are a gimmick, does anybody have personal experience with boost bottles? And finally is there improved pistons out there (canted, convex, concave) things of that nature?
