it is a mystery

Ya. If anyone has any ideas, feel free to post up....actually, I'll start a new thread about it once I have more data.

That is weird. The before/after boost with the IX turbo looks almost identical. And it doesn't seem like the IX turbo was that bad.

Do you know what compression was last year?

[JET]

Are you POSITIVE the timing belt isn't off a tooth? That could explain it. Compression seems decent, so that shouldn't be it and if you had the head done, then the leak down should come back ok unless the rings are shot, but that isn't real likely. I am sure you have done a boost leak test, right?

Compression was almost identical last year, and shane and I checked the timing on the dyno, it was good. Yes I've done several boost leak tests; I almost always do before going to the dyno; the only time I didn't was before my session a few weeks ago, and guess what I did when I got home and guess what I found? A few small leaks, nothing catastrophic though. I thought the IX turbo was going out but it looks now as though its fine.

I thought the same with my sweet 16G

Have you checked to see if the car is pulling timing for some reason? I would do another compression test just to be sure. The problem seems weird though.

[scheides]

Yup, these are fully tuned maps, no knock, no timing pull. When we first flipped on the alky, the car hit like 340whp at like 5800rpms and literally held it flat until 7300rpms, like it had just hit a wall for airflow or something.

[JET]

You checked the timing belt timing on the dyno or the ignition timing?

[scheides]

Timing belt timing. I don't think there's a way to set base timing on an evo, like you would on a DSM. The CAS is not adjustable.
