Chrankshaft orginal or a milled one

[frandecoolTopic starterBerichten: 43]

Hallo there.

Should i use a orginal chrankshaft or a miled one for the polinie evolution engine???:con

[November RainBijdragerBerichten: 535]

dunno what “miled” is but you need the one that fills te most space in your engine. This way the pressure is the highest which results in better performance

This is what i mean.

Look under how to`s

you mean: an original or milled (=gefreesde) crankshaft.

because the Evo Engine works with a membrane (?) intake, you need one like this : link JMPB parts

:! you can use an original crank just as well, but there will be somewhat loss in performance.

:! there won’t be any, or at least not much, difference between an original crank or a milled one, because the crankshaft is not a part of the intake system, like it is on an original engine 😉

I think i will try whit the orginal because 139 euro is a lot of money:'(

How much do you think i wil lose.

somebody on this site has got that crankshaft for sale, if it’s still there. he asks 99 euros I think. but i think it’s a 12mm one. so you need a 12mm piston too.

Yea thats fine but i need it now :lol
And my new cylinder kit piston whit a 10mm

Try it with an orginal crankshaft.

Its better to drive with 1 filled up one because that will get you the best performance.
