Ya I don't quite understand that if it truly is a 1.60 housing how a duramax ever spooled that thing....Maybe a ton of spray!!
S475/96tw and 200 Nozzels experience? BP?

One of our Borg turbo vendors has them made. So far so good with them. We have one in a pulling truck and now one in mine.

got some testing done with the new turbo now that its all sealed up and not coating my engine bay in soot. this thing is a monster, even at 5000ft. This wheel just has some great momentum, it takes a second coming off a light for it to get moving but its pretty quick to come to life. It will sing just driving down the road and getting on the highway with out even trying its building 3-5psi which is nice compared to my 71/83 where i had to spool it and just felt like a dog up here. I wish i had tried a bigger exhaust wheel a long time ago!
I havent tried much hotter of a tune besides my daily which made 30psi up here and the new turbo makes 35-37psi. Ill have to log some runs on the hotter tunes as this is a very mild/easy tune.
I was surpised to find that the truck is torquier and more responsive just driving around town. a touch of the pedal and you can hear that big ol compressor singing away where as my 71 would smoke a tad then come to life.

i came from the east. i was by boston mass with the 71/83 and it was great there. I relocated to great falls MT which is right at 5000ft and the 71 became a stone. Travis i was pegging out my factory sensor at 48psi up here at just 30psi with the other turbo. i havent had a chance to check out this turbo since i got it sealed up but its a new animal. its got to be a monster at sea level.

night and day lol my tony hot tune was down right stupid at sea level. youd blink and the 71 would smash 20psi violently. up here its completely usless and smokes like a train

yeah, really interested in how some of there setups react with the Altitude. Im sure you can just spray to make up for the air but just from my setup and air i probably lost 100hp or so after the move. given i havent jumped on a dyno yet to confirm but believe me, its something else. I cant imagine on a big setup that makes some serious power, the motor just snuffs out and is totally different.
