Re: Questions on whitch rods and pistons to use.
JET, on the issue of cylinder scuffing and higher silicon. Mahle piston's spec sheet says that .002-.003 is the recommended clearance. I believe the Wiseco's have a .0025-.003 recommended clearance. In all actuality, Mahle could possibly be a better choice.
1. They are hard anodized. This makes them superior in many ways over a non anodized piston. FYI they ring lands on the C6 Zo6 are hard anodized, and they have handled over 850whp so far. The Zo6 pistons are cast.
2. They also coat the "side skirts" with teflon. The Mahle pistons have more of a 3/4 skirt around them, where as wiseco's only have a half skirt. This may or may not make up for the lack of length on the skirt.
3. They come with a full wrist pin stock. While this add's weight, it also makes the assembly stronger. I believe this is like a $40 dollar upgrade for Wiseco's.
Now don't get me wrong, Wiseco makes awesome pistons, but there are some things about them not to like. Just because one piston is tried and true doesn't mean there isn't a better piston out there for a comparable price.
