Does anyone have compressor (sp?) maps for common junkyard turbo's? I rather try a single turbo setup but duel turbo set ups are cool too.

Thanks, Verv

 

Garrett charges on turbo coupes and PSDs can be found at egarrett.com or something similar. As far as the Holset, IHI, etc. turbos I'm not sure.

 

There are quite a few listed at www.turbonetics.com...

 

With the exception of the T3’s, and some of the Holsets you won’t find a turbo in the junkyard that will be clearly labeled in a way that you can relate to the compressor maps. A T04e 50 trim won’t have T04e 50 trim written anywhere on it. The holsets will have the model on there tags, but that isn’t that helpful, since there are quite a few of each one (ex, there are 9 different sizes H1E that I know of, and 6 HX50’s, there are 2 HX55’s that are smaller then most of the HX50’s, most of the H1D’s are smaller then the H1C’s even though the H1D is a “larger frame” turbo).

 

dont forget the Warner/IHI turbos like the GM-5 and GM-8

 

What about them? As far as I can tell, the GM 6.5L diesel turbos are all roughly the same size even though they have different designations. They’re also fairly small acting compared to a relatively large physical size

 

I found my mitsu flow maps here -

I dont know about all that stuff although when I look at the hulk of a GM-5 I have you can tell its huge size belies a small intent by the size of the tiny ports on it.

I also know that when 6.5 owners ditch the GM-3 for a GM-5 or GM-5 for a GM-8 the get a huge improvemnt in power.
