Questions on whitch rods and pistons to use.

[JET]

I would be careful with the Mahle, I don't know of anyone using them in a DSM personally. I know Shane put down nearly 700whp with them and there are several of us in MN with over 500 whp with them in. For a street car short side skirts are bad. They don't offer as much support and will scrape the cylinder walls more. For a race car that is an easy way to lighten the piston and make more power though.

Wiseco's also have a higher silicon content than a lot of pistons. This gives them a expansion rate close to the cast iron in the block. The key to that is that the hole doesn't have to be extra big when cold, so you get less piston slap on startup from a cold engine. I would definately go Wiseco. If you think saving 10 grams on a piston is significant for a street car, you need to do some more research.

*DING*

Honestly,the Weisco's are all around a better piston when you "add it all up" when concerning a street car.
1) More available
2) More support
3) Usually cheaper
4) Great piston design for a street/strip car, the weight savings are probably not worth it. I guarantee I can find something else in your setup that will rob your of more power compared to the few gram weight savings.

just to clarify, in jets first paragraph he is NOT saying shane and him use Mahle pistons; they use wisecos.

you probably got the idea from the 2nd paragraph, but i thought the first was oddly worded and that i'd just point that out
