Hohn, and others, here are some schwitzer/ borg warner turbo maps. What sense can we make from them?

Same as you'd learn from any other compressor map.

I personally can't make much sense of them because they are illegibly small.

I can't figure out what the "compressor spec" means. It appears to be exducer and some other spec, but those are VERY low numbers to be trim! I wonder what else they would be?

Wow, a GT 6041 ought to make a great bottom turbo for my 2000HP Diesel Drag Truck! At 180lbs/ min that aught to be plenty to feed a Phat Bastard top turbo.

It's not THAT big to where it would feed a PB. You'd need a turbo in the 240#+ range to feed that big of a turbo up top.

I'm guessing this would be an inducer size around 140mm---huge!
