pistons

[kawiking]

has anyone ever used WSM pistons in their shee's?

[letsgetthisdone]

i always use wiseco, everyone i know always has too.

[locogato11283]

ive heard of them. honestly idstick with whats for sure proven. wiseco has proven themselves time and time again. i see no reason to ever run anything but wiseco in anything.

That is unless you want to run 65.75mm banshee pistons or pistons larger than 66mm with a piston pin offset 5mm higher to accommodate a long rod crank or stroker. Wiseco does not offer pistons in these sizes. WSM makes forged pistons as well as cast pistons. They are made in Germany and last time I checked German cars are some of the nicest machines around.

WSM is what I'm running right now. I have zero complaints about them, and they were cheaper than the wiseco pistons.

[RedRustler]

i have wsm pistons in my bike now and i dont have any complaints to gripe about.

 

and also if you have standard cylinders the wsm pistons have a third intake hole in them that lets the wristpin get more lubrication. and they have bigger windows than wisecos

bigger windows with the third window ='s better flow

im running them right now and they are great no complaints and they are wayyyy cheaper

Fouledout421 uses them in his 4 mil cub done by Nate McCoy, and Nate will swear by them...

I get good pricing on Wiseco locally, or I'd use them in my 10 mil with no reservations.

[kawiking]

damn thats a old thread.. hell , i still have those pistons sitting in a box.

[dajogejr]

D'oh....thread miner, my bad...didn't even think to look at the date...

If you have a Cub, it uses the Blaster pistons, which do come in Wiseco. Not 100%, but I think you can get them up to 72mm. I've actually wondered if you can use the Blaster pistons in a stock cylinder big bore. Doubt it though.

[dajogejr]

You can use the blaster pistons in a stock cylinder big bore, if it's a long rod motor.

The blaster uses the same 5mm offset in wrist pin height as the 795 series wiseco, they're just available in different size bores (bigger ones)

 

HOWEVER...

 

Whomever is cutting the head or domes for the motor needs to know that because the crown shape and deck height is different for the blaster pistons vs. the banshee or 795 series.

did u have a prob with ur ring gap... mine was off, but i late blew my motor becuase one cyl was bored a tad to much

They look good but had some serious problems on the intake skirts, at least on the 68mm Blaster versions originally, hopefully they have it handled now. I scattered a 10mill Cub on the dyno and took out the cases, pistons, domes etc on a brand new set...and I'm not the only one who's had the same issue. .......Jim

I doubt it was an issue with the pistons themselves.If it was a totally stock engine,then more than likely the piston is to blame,but with any ported engine,I would blame the engine builder.

 

No piston was originally designed for the aggressive portwork that some builders utilize.The more material the skirt has to ride on,the more the forces are distributed.The less surface area a skirt has to distribute the forces,the more strain it will put on the main contact areas.Performance has compromised reliability.

 

Engine builders are quick to blame the manufacturer,but the manufacturer never intended the part to be used the way it was.

 

Wiseco are by far the strongest pistons made,but they are also the heaviest.So again,reliability compromises performance.Where you gain on one,you will lose on the other.
