Whats the general opinion on these? Heard they arent great?

 

Cant comment about the car pistons mate but i used to use them all the time in my 2 stoke bikes and they were by far the best! If thats any use to you at all

 

+1

 

mate too used them in his yz125, but for cars ive heard they're very soft and warp?

 

iv used them im both my starlet engines and never had a problem with them

 

Are you sure the soft piston comments are not getting mixed up with WOOSNER ?
I have used wiseco in many things never a problem, but that's been mostly n/a V8 stuff.

We all have our own favorits those arnt mine, For Me Mahle for under 500hp and CP over 500hp.

i think i am getting mixed up, i stand corrected

 

below 500hp, any forged piston is likely to be more than good enough.

 

I used them on my turbo bike project with no problems, I started with a 13:1 CR and they put up with det with no sign of damage, fitted a de-comp plate under the barrels for 10:1 and had no issues at all.

I've used Woosner many times on 400+ engines and never had a problem. Many cars have been used on track, including our Irish Time Attack Evo, which is the current Irish champion.

I'd go for Wossner

No mate, but I will be getting Dave to map my car when I finally get it done !
