Unfortunately I don't have pictures of the new pistons (battery on my phone was getting low), but I did see them. There are some subtle differences. The skirt is a little bit longer and that land has a bit more material below it. The upper ring land is in the same place as the last forged piston but they added gas jets to keep it pressed out at higher RPMs. I had never heard of this but it seems to be common for race pistons (I looked it up before posting so I knew something about it LOL).

Although Aaron couldn't see any signs of blowby but the guys at Wiseco said they could see some and suggested we add the gas porting and stronger compression ring. Hopefully everything is built to handle the power now and we get to put down some good ETs/Traps.
