A GT35R is a big street turbo but inconsideration of race turbos, is on the smaller size. That turbo ia a 65 lb/min turbo. that almost 650 hp rating. Now a larger turbo rated at 850hp would make 650 hp at a lower boost because you arent maxing out the flow rates. Its as simple as saying a a 50trim at 15 psi can make as much power as a 16g at 21psi. It isnt just boost pressure, but to maximize potential of the tubro, you do. All the fast guys in DSMs run 35plus psi, and they are making almost the peak power of their turbos rating. so can someone make 648 hp on 28 psi?? sure, i bet its big,. and with that low of boost on a big tubro the graph was almost flat until it started to spool and make any kind of power. And that lag, isnt a good drag turbo unless you are launching it at 7k and keeping the rpms in the range where boost is being made.
