Compression Ratio Confusion... help!

Bump bump? :O)

Anything? lol! :O(

The Seal Power H802CP shares the same CH 1.592 as the H825CP along with the same dish volume.
The difference between the two is that the H802CP piston uses a metric ring package that has less radial tension.

less radial tension.

I would go with the H802CP for this reason.

 

[svshaw82]

So its better to have more radial tension or less? Seems like higher would seal better, or is the pressure against the cylinder wall too excessive

 

[Talyn]

Less radial tension = less drag. Both seal equally well.

I have about 120k on my 4.7L stroker with the H802CP's

 

[svshaw82]

Sounds like the H802CP is the better ticket?

Thanks guys!!
