1st: .8 bar(11.60psi) 254whp@ 6200- - 244 lb/ft@ 4800 A/F 10.8 -10.12nd: 1 bar(14.50psi) 275whp@ 5900- - 276 lb/ft@ 4700 A/F 12.2- 10.13rd: 1.1 bar(15.95psi) 280whp- - 291 lb/ft, shut down early due to detonation(13.1 a/f)4th: 1.1 bar(added fuel) 277whp@ 5900- -282 lb/ft@ 4900 A/F 12.7-10.1
The a/f readings I listed were high/low readings.
Just seems to me that the turbo is good for around 1 bar. Then starts blowing hot air bringing the torque up tremendously. The consensus on the GTiR T28 is 14-15psi is the max.
So I am happy with the outcome and will take my 1 bar to the track next wed, looking for 7.xx @ 90+mph.
The dyno chart doesn't show pull # 3.
Cams and 3" downpipe are in the works.
