LeX Posted November 4, 2008 Share Posted November 4, 2008 RB20DET RB25 turbo @ 13psi FMIC walbro 255 2.5inch downpipe and 3" after that SAFC-II tuned by very good local tuner performance wise that's it. When i got the car it already had the tune on it and i've never had the car put on a dyno. Any idea what sort of power I should be making at the wheels, for curiosity and boredom's sake? lol Quote Link to comment Share on other sites More sharing options...
Evan Purple240zt Posted November 5, 2008 Share Posted November 5, 2008 215 rwhp, what did I win? Evan Quote Link to comment Share on other sites More sharing options...
Careless Posted November 5, 2008 Share Posted November 5, 2008 I'd say a bit more. Closer to 225? Quote Link to comment Share on other sites More sharing options...
slownrusty Posted November 5, 2008 Share Posted November 5, 2008 As a good rule of thumb, ever extra psi of boost adds between 7-10hp. Go conservative and say its 8hp in your case per psi of boost. Stock RB20 is what 8psi?..so that would be an extra 40hp at the crank as you are running 13psi. That takes you to 230hp at the flywheel (stock RB20DET is 190hp right?)....figure 20% drivetrain loss, you are at around: 185whp Yasin Quote Link to comment Share on other sites More sharing options...
jerryb Posted November 5, 2008 Share Posted November 5, 2008 A Stock RB20 ..R32..is 215 at crank.... Quote Link to comment Share on other sites More sharing options...
LeX Posted November 5, 2008 Author Share Posted November 5, 2008 i'm hoping for around 225whp.. i think so maybe since it does have a top level tune (at least for an SAFCII) and the bigger turbo. Gonna get it dyno tested as soon as I can Quote Link to comment Share on other sites More sharing options...
