День добрый!
Хочу поделиться опытом решения проблемы недостаточного наддува на моей машине, напомню "Subaru Forester sf5 99' двигатель EJ205"

После исследования некоторых англоязычных форумов, таких как
epifansoft.com subaruforester.org

Очень быстро нашел решение...
Проблема является очень распространненной для моторов до 2001 года, у которых байпассный клапан с двумя вакуумными штуцерами, и решается элементарно
Вот выдержка из поста
"-Simon, tell me please about boost on forester!
engine EJ205NWYKB? and I have only 170 hp
When I look my logs by program "ecuedit", i see that my max boost is about 0.45 bar.... Is it normally?

-OK, stock power is 168bhp for 99/00MY (and 177bhp for 01My on).

Your stock boost should be between 0.5 and 0.55bar, mapped against rpm, if you aren't getting that its possible your recirc valve is leaking, this can be fixed by deleting the pipework to the chamber closer to the intercooler. Boost should be at 0.5bar from about 1600rpm (fifth gear) if its not its a sure fire sign that the valve is leaking (common fault).

The pipe marked "5" has two connections to the recirc valve. If your's has the two connections the pipe to the connection nearest the intercooler needs to be disconnected and the open pipe plugged. Leave the connection on the recirc valve open.
This gives greater pressure drop across the valve diaphragm and will help keep it closed.
-Can you see my log? pressure become bigger, but not standart!
before removing pipe 0.38-0.43bar
now 0.45-0.48 bar
-Stock boost is "0.5 bar" (read from a multitude of means, but most 50mm guages) rising only to nearer 0.55 at the red line, your log doesn't go over 4000rpm and I'm not going to quibble the difference between 0.48 and 0.5 bar!"
В принципе все стало хорошо, я доволен.
