MBC installed

[QuA]

Ok im not even sure if I installed this right. But after a few runs my spikes are even higher then before so i lowered the boost, but i dont think its adjusting it lower. It pulls pretty damn hard. I hit limp mode a few times.

If I install incorrectly would it not even work?

Re: MBC installed

Ok I did more testing this morning and hooked the Turbosmart MBC to the wastegate tube line and then right to the n75, the TIH part of the n75 is still in there same with the other hose. Electronic part is connected still as well.

This morning I didnt hit any limp mode. I was still seeing 19-20 PSI spikes in 5th gear which i want to lower around 18. My 3rd gear has changed for the better. It holds at 17psi till 5000 and drops really slow. 4th gear holds around 17-18psi and then drops really slow. I'm still not 100% sure I even have this hooked up right. It seems like its working

Re: MBC installed

Ok during my lunch break i tested the car and put as least amount of boost as possible. The car was still doing boosting the same. I think instead of hooking up in the line with the waste gate actuator im gonna try the other line that feeds to the compressor i think.

Replaced N75 with inline pressure relief valve and pressure regulator valve.

There is a check valve letting air flow backwards to prevent wastegate creep.

One problem with pressure relief valves is that they usually have different pressures for "cracking" and staying open...

Re: MBC installed

Ok,

I got the MBC working to control the boost. However this MBC can only handle 15-16PSI. So im thinking about getting a boostvalve strong spring MBC to hold this damn boost. But when I hooked it up wrong before and was holding 20 PSI... DAMN that was fast.
