Turbo Data Base

[johnl]

I have a knowledge gap in terms of basic turbo specs.

The gap is made worse by retailers and manufacturers who use proprietary marketing language that's good for them but bad for us.

I don't want to learn their boogie woogie terminology - tell me what the part measures! When I know which part is bigger or smaller, I can envision the rest.

How about we all contribute data to a data base that compares the specs of turbos - dimensions of wheels, OD/Height of inducers/exducers, OD/Height of turbine wheels, wheel fin counts, ID of compressor inlets/outlets, shaft axial play, inducer to compressor housing clearance, compressor base to compressor cover clearance, A/Rs and so on?

Because we do not have such a data base, we have no way of knowing whether a used or rebuilt turbo is "Go or No Go." This is especially so with respect to remanufactured covers, shaft axial play, and wheel to cover clearances.

What format, best way? Good idea?

That is a good idea. Some of that is covered on thedodgegarage.com and other td sites as well but not compiled into one place.

Sizes arent cut and dry as you think. If you look at the sizes between the different garrett generational wheels, you can see a huge difference. Your best bet is to just compare compressor maps even though some o fthem are computer generated, not based on real measurements. You can find the database of compressor maps at my site.... http://www.squirrelpf.com
