Re: Adjust boost on GT25?
by by motor! the reason u not feeling gains is cuz standar ecu can only suport 0.8 bar then you run lean give it another month or two your valves are gonna burn or you gonna get a knock

1bar is very very close to the maximum rotational speed of the compressor on the t25..

you right if he has disconnected the waste gate then the turbo is going to spool to its max the turbo isnt gonna last long and the motor isnt either without a fuel management system300sx wrote:1bar is very very close to the maximum rotational speed of the compressor on the t25..

Go get some dyno graphs, youll see your power fall down after 5500rpm on that small turbo at 1 bar

Re: Adjust boost on GT25?
ah ok, i get it.. just out of curiosity, if it does fail, put a few pics up.. i for one would find it interesting to know what first point of failure is, turbine or compressor..Obsession wrote:Well aware, like i said, testing something....300sx wrote:its not that the turbo wont do this.. its just that it wont do it for very long..Boost goes up to 1.2 bar at bout 4300rpm from 3rd and up. and yes, u can feel the power drop from 5700rpm

Re: Adjust boost on GT25?
HAhahahahaha....Will do, u can even come and study it....
On my old motor i ran that Skyline turbo from the RB25Neo2...The one with the ceramic compressor wheel at 1.2bar, used to boost creep to 1.3bar, and max was said to be 1bar before it would destroy the compressor wheel.....funny enough it destroyed the blades on the exhoust wheel and also after 9months....
