Re: gt28rs/jwtbb700 updated flow map ? " Hi Dee,
I can't find a test date for the new map on the Garrett site, so I'm not sure where it came from. What ever it actually is, it doesn't show data above the 144K speed line or wasn't tested. This may be someone's way of encouraging one not to go their! Attached is the original map with speed lines up to 165K. The compressor and wheel haven't changed (T3 62trim .60 A/R T04 HSNG LARGE "B" width WHEEL) on the GT28RS from the original map. The original map was used here during testing in 1999 on the "Disco Potato Sentra" (Nissan/Garrett project Sentra painted a gold brown Chrome Illusion color, looked like a Disco Potato. The Disco name interestingly stuck with the turbo after the project car retired to Nissan's museum.). My notes show a very good correlation to the original map for speed and eff. With as many TT cars actually butting down 650+hp at the wheels, I'd say the original map is a much better look at this compressor combo when pushed to the limit. P.S. ignore the hand drawn lines on the left of the map, I think they are old notes on a port shrouded inlet. Best Regards, Jim " Flowmap provided by Jim Wolf original post about an upgraded flow map my initial post yesterday unverifiable GT28RS flowmap
short story - the GT28RS / JWT700BB can handle 28PSI based on the original flow map ( assuming the proper setup on the Z )
