My Progress

[JET]

Well I went to the dyno today.

I'll just say that my car went up in flames on the dyno. :( :fworld:

Hopefully it isn't anything too serious, the head gasket had a catastrophic failure due to boost creep. It went from 20 psi to 28.2 psi in .7 seconds at 6k rpm. There was no knock, but the AFR's did go lean right at the very end. I will be pulling the head Mon at the latest or whenever I can find a 2.4l head gasket. I may try a stocker, but I really don't want to.

I did make 353 whp and 321 torque. The torque was flat from 4k to 6.2k, partly due to boost creep. It started at 17 psi to 5k, then up to 20, then it went balistic from 6k to 6.2k. So, the lesson for the day is twofold. Do your first dyno on C-16 for safety's sake and a stock PTE housing won't flow enough out the wastegate with a 2.4 and a larger turbo.

I did notice that the lower radiator hose is hitting the shifter for 1st and 2nd though.
it could be on backwards...check that, i know from experience...

i know this is the least of your problems...but just thought ide throw it out there

sorry to hear that man, that's a total buzz killer.

I am pretty sure it is just the head gasket. It didn't get lean until the boost creeped so bad that the boost comp table in the AEM couldn't keep up to add more gas. The AFR was good for all but the very end, and for a split second it went to 13.8-1. But the car didn't hardly knock at all. Not enough to cause that kind of blow out you wouldn't think but something happened in there. We won't know until we pull the head off and see what happened.

That is sad to hear, hopefully there is nothing major wrong and a HG is all thats needed. What type was on there?

[TheBlizzard]

Cometic HP.

I had to bend my water pipe back to clear the turbo. That is what caused it to get closer. And the fluidyne radiator is also thicker. I cut off 1 1/2" and all is good now.

Well, none of us know exactly what happened, but the melt down was more severe than we were hoping for. The car never went lean except for the very end of the run (like .2 seconds), but something was definately off. I am thinking there must have been a value in the AEM that was setup different between mine and Mo's ECU.

I melted some good sized channels into the head, matching ones through the head gasket and melted the sides of the pistons a bit. The head looks fixable (you will be seeing it sometime Mike) but she needs new pistons and probably bearings too. I am thinking it had to be something with timing to do it, but I am still unsure.

I will post up pic's tonight.

OH damn dude, that's horrible news, especially with the shootout right around the corner. If I were rich I'd buy ya some new pistons, but I'm in the military, I can barley afford converse shoes.
