Hi guys another update..
The Overboost/Dump valve is finished and was quite and expensive idea, once you machine up aluminium ferruls, 4 port solinoid, price of braided lines and the wastegate itself. Total was well over $1000 for the setup but will be worth it.
Overboost:- Will be setup if the turbo Gate fails and will vent off excess boost at a predetermined setting in the computer.
Dump valve:- Is an idea that a few of the boys (Gas motorsports, Godzilla Motorspots) are running with so that you can be instage with turbo producing full boost eg. 40PSI and be venting the majority of it to atmosphere. As we than through the Vipec V88 computer ramp the boost on with speed or gearchanges..
Hope this fills everyone in..
ProGate 45 was a cool $500
Solinoid on the left is Turbo Wastegate still gota plum in manifold pressure line,
Solinoid on the right is the 4 port for the Overboost/Dump valve and also needs manifold pressure line,
