stroker hp ??

[LT250RMan]

I'm thinking of buying a hot rods 4mm stroker crank and was wondering does anyone know how more hp i will gain roughly ?

i think you need to do some research on hotrod cranks. do a search in this forum.

I would estimate it to be around a 3 hp gain. With the bore size remaining the same it makes about a 14cc difference in displacement. I just got one running this afternoon and am dialing it in. I hope to get a dyno run of it soon. I did go down four sizes on my bore size as compared to before, but added the +4 hot rods stroker crank. Initially I can feel the power difference which is impressive, but my old motor was whooped out!

well i have to say i did this once before. i do know you will need a top end with the timing ports for a stroker i didnt have it and the motor had inconsistent power

hp gain will be minimal since you are increasing displacement marginally.

if you go with a hot rod crank, don't even think about installing without getting it trued, welded, and balanced.

your stock stroke-cranked cylinder will need to be reported as everything will be off.

I decided to go with a CT Racing Pro-x 330 complete power package, thanks for the info guys.
