after removing my rats nest and ACV i realize i don't really know were to T into for my mechanical boost gauge. 89 13bt S5. any suggestions? also were is the best place to hook the vacum for the blow off valve(blitz)

I think I read somewhere years ago when I hooked mine up that the best place was the line to the FPR. |
hmmm ill give it a try. just seems odd i guess

I knew I wasn't crazy. From the hitman's old site, which I found on the evil forum, and I quote:
Map Sensor : The Map Sensor should be located in the engine bay away from any direct heat , and it should also be mounted higher than the injector locations so as to not have any fuel run down the vacuum line and kill the sensor. The vacuum line should be connected to a constant vacuum source such as the inlet plenum , or a place where it gets a vacuum signal from all rotors or cylinders. If the vacuum line is connected to the inlet manifold where it only gets a signal from one runner, that signal will be very erratic and it will pulse. This will make tuning very difficult due to the constantly varying vacuum reading. A good place on the 13BT motor is the bottom vacuum port near the Throttle Position Sensor on the intake plenum as seen below. This port is the best to use because it has little or no pulsing which gives a more consistent tune. Connect MAP sensor to bottom port. It is a good idea to also run your boost gauge and the fuel pressure regulator from the same source. That way all components read exactly the same signal. End quote. |
thank you
