Hi guys,

Do any of you have a compressor map for a Garrett hybrid turbo - T04B cold side with 67.5 mm compressor wheel and T3 hot side with a 64mm turbine wheel. My turbo toasted big time and I'm just toying with the idea of going for a different unit but need to see how others will compare. I was never completely happy with the Garrett as I always felt it ran hotter than it should at full boost, so maybe this is the time to change.

Cheers, Bruce.

Turbo maps are a little hard to find but Garrett is the easiest. They have a website someplace that has a bunch of 'em. Google what you're looking for. However, I think one for a hybrid will be a bit tougher because unless the combo you're after is something the factory is doing, there won't be a map for it. (you might get close, but...)

I was under the impression that a compressor map is just that: a map of a given compressor wheel, which would be independent of the turbine assembly to which it is attached. if i'm right, it shouldn't matter that you're looking at a hybrid...but I might be wrong...
