How much horsepower can Probe pistons handle?
There really is no limit. Probe forged pistons (SRS Series) are machined on 2618-t6 blanks and can handle as much horsepower as any piston made by anyone. The truth is, its all about the tune-up. If the mixture and timing are correct youll never have a problem. If they are not, thats when you run into problems no matter whos pistons you are ruining (we mean running).
