    Here are the numbers of the turbo. I know the help identify turbo stuff gets old but i just want to see iof he can use this turbo or if he got screwed.

    AirResearch
    Detroit Diesel Allison
    Numbers on center tag -----5102117 & JJ0331


    Hot side AR is a huge 1.84
    Cold side is .95


    could this turbo be used in the future? He obviously doesn't have a 600+ ci motor to spool it. But what would it take to make it work with a 383 sb motor.


    Guys thanks for any help.

    Divided turbine inlet? How big is the inducer on the compressor?

    Not sure what size turbine wheel you've got, but a 1.84AR sounds pretty big for a 383 if the wheel is large. If it was a divided scroll, you could have looked into some of the approaches to sending all or most of the exhaust flow into one of the ports to get it to spool, but this one is undivided. My guess is you're going to have a tough time getting it to spool on a 383 at any reasonable rpm without feeding the engine nitrous to "bulk up" your exhaust flow to get this thing spinning.

    Moving over to the cold side, if you can get a measurement in mm of the compressor inducer diameter (blade to blade) you can start looking at maps of compressors with similar inducer diameters to at least get you in the ballpark of how much air this turbo can move. A rough rule of thumb is every pound of air it can move per minute is good for 10hp. Is this turbo a Garrett?

    Looking over your post again you said it was an AirReseach which is a Garrett. You could look at Garrett's current catalog but it is likely your unit is old school and may not produce as much as the current models. Here's a link once you get the inducer diameter:

    If it turns out this is a TV8101, you should be able to find the map for it even though it is not in the current Garrett catalog.
