Do stock ringlands have a limit? Future build question.
I'll be quick. I don't really see ringlands being discussed or what the limit is of stock piston ringlands. Anyone know or can anyone share what they have learned/ experienced?
I want to do a rods only build and my goal is 300-350hp using strictly e85. I want compression to be at least 10:1. I've seen one example of a failure and i think they were around 270hp but I've also read plenty of builds using stock pistons and are well above 270hp. |
Ringlands have a thermal limit. It's not like rods where you have a torque limit, and if you exceed that limit there is instant catastrophic failure. You can destroy the ring lands with lost boost but long load time or high boost and short load time. In general, anything above 250 and you are limited in how long you can retain full boost.

When running 11.5:1 AFRs, was probably barely holding on, but it did hold on with 28 PSI boost. All E85 of course. |
