I want to run my JRSC with 13.5 psi of boost and water injection. Therefore i need to reduce my 11:1 stock cr to something like 9:1.

How about the thickness of the head gasket i need ? 2 mm ?

Is it safe to run the JRSC at that boost level with a thicker head gasket ?


BTW: RC 440 or RC 550 for that setup ?


Thanks

 

dont run it past 11psi and do not use a head gasket you will lose power

 

Don't do it or you will feel this pain
Jrsc's don't like that high of boost, that rpm can be bad for the blower and with that kind of heat you will be at the point of "diminishing returns". In other words you will lose horsepower. Run it at 10-11 psi and spray some nitrous on it
