Heath just got it, but alas I goofed in packaging, I surrounded the turbo I plastic & Great Stuff expansion foam, well seems either I forgot to cover the drain port, or the tape I put over the port came off, and foam got into the oil drain cavity locking the rotor, minor setback, turbo going to shop this week for disassembly/cleaning this week. Hopefully guys at heath will get some slack time from Bonniville truck to have time to play with turbo.
Chinese turbo spools faster than Mitsubishi, towing boost is there, max 10-12 psi at WOT 100% engine load, 82mm fuel, 0 psi lift pressure (heath h/o lift-time to install my Walbro) max EGT 1100F could maybe get more boost if I had more fuel to put to it, on grade 3000 rpm in 3rd I was sucking all fuel lift could supply to the IP, max water temp 212F, 7x7x16 tandem axle trailer loaded to estimated 5000# combined load/trailer 80 mph if I kept in it on grade, running 73 mph to conserve some fuel mpg wasn't greatest 9-10 depending how hard I pushed it, and how much uphill driving. From Ms coast (sea level) to Iowa via I 55 mostly just about uphill all the way.
I also have about 300# in bumper on the front, and had 60 gal of fuel in the bed, (2) "robust" sized passengers, & luggage, all in all a good ride to Wapello Iowa, and back

I just towed the 96 K2500 Burb to my buddies house on flatbed trailer about 22 miles away, newver missed a lick there either, getting ready to swap the 98 Burb engine/trans into it, coming back home sans trailer, I "goosed it some" 100+ mph according to speedo at 1 point and still accelerating when I got off of it 10 psi boost was what it was showing, remember basic physics class, pressure/volume are inverse of each other, so while my China turbo isn't making big boost pressure it's more efficient compressor is moving more volume than the GM-8 at same pressure, plus less backpressure, 10 psi boost GM-8 nets about 20-22 psi backprressure , China & Mitsubishi turbos are 15 psi avg Bp at 10 psi boost, and volune of air supply is what it is all about.
Again this turbo is best suited for towing and better economy over GM-8, guys needing to convince the wives, hit them on the economy angle worked for me :thumbsup::thumbsup::thumbsup: I don't know what China turbo best mpg is as I installed it a couple of weeks prior to the Iowa trip, but the Mitsubishi when driven 73 mph with my 3:73 ratio set I was seeing 20-22 mpg, with GM-8, similar EGT and backpressure to the Mitsubishi turbo, so I'll extrapolate and make SWAG and say China turbo should be about the same mpg. Are these
THE best turbos for the 6.5 who knows, but are they sufficient for vast majority of the 6.5ers out there; you bet-cha.
