The Ultimate Piston poll!

wsm all the way

[T_Shee]

im running wiseco right now but only because i traded top ends. i had just rebuilt my last top end with wsm platinum series and i was really impressed with the quality. cant say much for durability since i only had maybe 10 hours on them when i swapped. the rings wsm uses are extremely tough looking. they look to be a lot thicker than wiseco rings. my next rebuild will be with wsm pistons, not to mention they are about 50 bucks cheaper

[dirtydownunder]

if they have thicker rings and its not needed, thats more surface area on the bore so there will be more drag = less power.

 

has anyone got pistons weights ? pin and circlips included ?

[camatv]

i would vote for wiseco's that were built 3-6 years ago. if you look at the bottom there should be a lil bitty W on them. i believe if the W is not there they are the "newer pistons"...

 

wossner and vertex pistons are also nice. used vertex in dirt bikes for a long time..

that is not nesicarily true....depends on how they are designed. also, it may be to help prevent sticking and/or deflection for a longer seal life. another thing about wsm- their ported/windowed piston is the only one made to retain structural strength with the extra boost port and widened windows, as apposed to a modified piston, where you risk it breaking.

I've been keeping my eye on that as well...

I gotta get a new set of slugs for my motor this year, hopefully it's not the case.

With the state of the economy, it wouldn't surprise me although I would be dissapointed.

 

Vitos for a stock piped bike. +5 WHP

Weisco or wsm for ported bikes because the exhaust duration should already be ideal

wiseco pro lites hea !!!!!!!! they are running strong for me.b ut then again i have a je piston in my 686 raptor and thats running strong also.

speaking of "other aplications" the first thing i looked for when i got the shee was sealed power teflon coated pistons, lol. they had a verry noticable improvement in throttle response and power in the hp454 i built for an airboat.....man, that thing ran

Have your own done.

[AKheathen]

that was my origional plan with the cp-9 friction/ceramic combo from swaintech, like yours......in a prolite....but i heard/saw pics of major galling, but idk if it was oil starved or not......anyways, i decided to go with the wsm ported/teflon piston

[noscuda]

i dont know about the banshee's yet but i run diamond in a 360/408 stroker sb mopar with 100-300hp of the laughing gas have 5 yrs on them several other problems but same pistons one even has a little ding from a valve still np

[mercury65]

well thought i would let this one run a bit to see how long it would take for some one to say that vitos pistons are wisecos funny no one has.

Wiseco is all I will use!

wiseco

probably because everyone is running wisecos from wiseco, not wisecos from vitos.
