stroker pistons


Recommended Posts

can you run stock pistons with a 4mm crank?

 

You can with a 110mm rod. But I advise against it because

 

1. Stock pistons are cast, not forged. The piston speed will be increased because of the longer stroke and it will most likely cause a failure.

2. 115mm rod provides a more reliable rod angle vs. a 110mm rod. Using a stock cast piston with the longer stroke can cause great wear and stress on a cast piston's skirt.

795 wiseco pistons are used with a 115mm rod. 513 for use with a 110mm rod. So, you can run a 4mil stroker (with 110mm rod) with 513 style piston or a stock stroke longrod with 795 pistons.

 

 

If you run stock pistons on 110 rod stroker you still need to either cut the head or run a spacer.

The 795 is not a "stroker" piston,it is a longrod piston.

If you run a 4mil long rod with the 795's you still need a spacer or cut domes. The added 5mm pin height on the 795 is made to compensate for the longer rod,you still have to compensate somewhere else for the added stroke.

 

Even if you run a 795 with a 110mm rod stroker you will end up with negative deck height or the pistons would hit the crank

Of course theres lots of crazy setups,and im sure someone has set up something im not aware of
