    honestly, for something like that, you could teach for an enitre day, but in the end, going to the squirrel performance page is not only faster, its more foolproof...

    BTW: i've only got about 680 BINs left to label.... then comes the organization...

    i'm thinking of posting it on TPB... its only about 15MB uncompressed. i'm sure other people could use the help...
    1995 Monte Carlo LS 3100, 4T60E...for now, future plans include driving it until the wheels fall off!

    Need a wiring diagram for any GM car or truck from 82-06(and 07-08 cars)? PM me!

      unless I'm missing something (and that could very well be the case), the squirrel calculator doesn't really take turbine size into consideration.

        it doesn't need to. in the end, its about whats flowing air most efficiently for your application.

        since the compressor maps have the info you place into the calc plotted on them, EVERYTHING is taken into account.

        not sure what a bigger turbine would do: select a different turbo from their list that you know has the same compressor.

        look at the changes, see if there is any benefit, if so:

        GOTO 10

          Info about turbine selection is meager, at best. Here's some excerpts from Maximum Boost that at least provide some "rules of thumb" considerations.:

          I found the discussion about turbine exducer size to be interesting, but would have preferred to see something a bit more in-depth on selecting a turbine A/R ratio.

            thanks for posting that. I do own that book (although a friend is borrowing it).
