Default N75 Relocation

We've noticed that stage3 cars can eat through N75s pretty quickly. Because it sits at the top of the engine bay above the turbo and exhaust, it can get quite a dousing of heat. If you've ever driven your car hard on a nice summer day and after parking for 5 minutes popped the hood and touched your n75 valve, you've most likely noticed it was VERY hot. We theorized that the heat cycling might play a part in reduced n75 life expectancy.

In order to move the N75 to a cooler location, we need to extend the electrical. Bosch EV1 connectors are pretty easy to find online and pretty cheap.

We decided to move the n75 behind the firewall to keep it nice an cool. It's <b>VERY important</b> to be careful to route the hoses in such a way that they will not kink. If these hoses kink, you run the risk of over-spinning your turbos to death. We also used hose that does not easily kink.

We ran the vent back around into the engine bay and to atmosphere for the time being. The hose could be run back to the original vent location

Now after running the car hard, the n75 is nice and cool to the touch. Only time will tell if this really affects the n75 life or not.
