Dyno results at AMS 57 hp increase
Had my 200sx tuned at AMS today after upgrading the turbo from a t25 to a t25/28 hybrid (t25 housing with t28 compressor and turbine wheels) and a 3 inch downpipe.
Results
15 PSI: 282.90HP/275.24TQ (57HP & 61TQ increase)
7 PSI: 229.42HP/202.01TQ
The boost spikes to 15psi and holds it for a bit and drops down to 13psi.
Last Year Dyno Results with t25 2.5" downpipe
9-10 PSI: 225.11HP/214.16TQ
About the same as the t25/28
Chris Black the tuner said I have plenty of fuel and see's no fuel issue's going over the 290whp mark (injectors are at 4bar rated at 290hp). The plugs were gapped at 20. He also felt the boost could be raised a bit more.
AFR 11.2:1-10.7:1 (playing it safe)
The car feels much quicker then before. Boost comes in a 300rpm later. I am very happy with the results
Power increase from last year t25 vs hybrid
7psi vs 15psi
