Cause if it's just the clutch, that seems like a really simple problem to get in front of. |

If its just a clutch issue, someone could come out with a nice twin disk to take care of the problem.

Tons of X3M/X4M guys have been running stage 2 tunes including myself for many miles and no issues so far. Sure you get an outlier, or someone that gets bad gas, or miscalculates their ethanol mix and we all know what that leads to... |

Did anyone notice how much torque this motor is making? Basically double the amount of torque as the stock s58 yet at the same rpm, those were some magical turbo's
Not sure what they were doing to the head but it seems they lowered the compression even further by taking out material. |

@forcefed it looks like a port and polish. The screenshot you have is performing the "port" part of that by increasing the size to align better with the gasket and block it's getting bolted to

Porting and polishing is done inside the intake/exhaust runners. Some clean up is often done from the combustion chamber side, but this picture shows fresh metal in the first combustion chamber compared to the second which leads me to believe that they are CNC machining the combustion chamber. Plus the tool doesn't look like a tool that would normally be used for port/polish. It's been a long time since I've done head machining though, so take what I say with a grain of salt. |
