Hey

You're late to the party. I'm already back. 400 miles round trip door-to-door.

I'm sending you splitter along with a few other people's parts that were held until after the 1st of the year this week.

This is the missing piece from the #4 cylinder of my 2.5 951 engine.

This engine had ARP headstuds and MLS headgasket, pretty high boost too.
But when the cylinder broke i did not push the engine hard at all.

Sorry to see that happen George - you have quite the devotion to the 944 to keep going!
I have quite a few MIDs out there with lots of miles on them - this is one of the situations where they shine - you can't have this type of failure with an MID engine.

Do you know if this happened under full load or just afterwards? If you have a significant head gasket failure while under load you might not see it on the dyno until you close the throttle - then the coolant will be sucked into the cylinder and hydrolock the cylinder - that could easily blow out the cylinder wall (or bend a rod)

Amazing the similarity in the shape. My guess is the crack starts at the top and propagates nearly straight down then the "ear" rips out catastrophically.

George- Sorry to hear. I have a 3L Darton MID from since 2007 and have since put 10K into the motor on pump 93 running up to 1.45 bar without any issue. I am only making 400hp with a smaller turbo so no where near 500+ that you and some others are running. I had mine built for strictly weekend, street/show car and at this current hp level, is a hoot to drive.

Sorry, I was thinking Payson.

George,
