Carbon seals are light and work great in n/a high rev engines yes. And they are rotor housing friendly sorta, but they wear out FAST. Unless you like rebuilding or "freshing up" your engines frequently, use a better seal (like ceramic or at the least stock or RA super seals). IF you don't mind "refreshing up" your engines frequently, then by all means use the carbon. BTW, they don't take well to high heat or even small pings, so use race fuel and don't be too aggressive with the timming.

[QUOTE=Kyrasis6;7460822]Ouch, that is some rough port work, isn't that called a monster port though? Basically cutting a bridge port deep into the water jackets then filling in the coolant passages around it to get something as close as possable to a p-port?


Yip,its a monster port.Same problem as BLuem had.Rules banned Peripheral port,because the 2.2 Multivalve engines couldnt keep up.

As it doesnt have a starter,it gets push started,and normally comes into life at about 2500 or so RPM.

Holy ****!Look at the strange port!I will have to try that some day!
