ну вот видишь, все должны пройти "крещение расточкой"

PS. во, нашел! подтверждение проблемы с овербустом на непортированной Evo3 16g. пишется что на маленьких бустах 15-20psi (=1-1.4) возникает передув.
"We had only linited time today to get the test done, we had a few dyno appointments. We did manage to spend some time with the MHI Evo III turbo however, notice on the 15 PSI graph the boost crept from 15 to 20 psi.... the opposite problem we have been having! This was an unported turbo with no 34 mm flapper to help control boost creep. It was only an issue when we tried to run less than 20 psi however.
15 PSI: 290 ft/lbs 344 WHP (crept to 20 PSI)
20 PSI: 344 ft/lbs 344 WHP
25 PSI: 400 ft/lbs 375 WHP
30 PSI: 436 ft/lbs 397 WHP (fell to 23 PSI at redline)
We can easily make 400 WHP if we wanted to run more timing, or if we were on our old 2.3l motor we liked to beat on back in the day! We will have this turbo back on once we go external as well."
