i know the topic has been covered a trillion times, i know the best thing to do is through the bonnet release cable gromet....but i dont have small girlie hands. is it ok to run the boost hose down the side of the battery and through the passenger foot well? the hose is only going to where the clock used to be not all the way to the pillar. am i still going to get accurate readings off this? i plan on t'ing into the balance pipe where it normally is, is there a better place now that its going in the other side?
Hah, I was seriously trying to think 'hmm, whys that?' as I was genuinely intrigued... maybe he had something, maybe he discovered some new bit of information, and could enlighten the rest of us... ... Then I saw who posted it lol MoulaZX
Balance pipe area should be fine, im sure most of us have it there. its a rather long route going from the balance tube through the passanger footwell area, it should be fine as long as it doesn't kink.
i can't see why it wouldn't be accurate - assuming you have no leaks, once you start the motor and pressure is through all the hoses it wouldn't matter would it?
no problems, quick question. Why didnt you get an electric boost guage so you only need to bring the wires into the car instead of the tube itself? doesnt really matter, but for some reason i think its easier routing wires as aposed to tubing.
Even with leaks it will still be accurate. Even if you have huge leaks its still accurate If the air positive leaks out.. it still measures the pressure at the sensor. Assuming the pressure at the sensor position is an accurate representation of the manifold pressure, which it should be unless the lines are all twisted.
hmm thats interesting. i swear i have boost leaks, and im runnin OEM boost atm, and my EVC is showing 9psi, which untill now has confused me. would that mean my possible leak is after where the sensor is? where is the sensor in terms of the system anyways
I have just run some wires from the engine to the cabin by way of the driver's side wheel well. There is a large rubber grommet where the wires go to the footwell fuse block. The grommet pops out (and goes back) pretty easily. I found I could get my wires through there. Stick a torch in the grommet hole and look from the inside and you will see the light Space is a bit tight but I reckon you could get a vacuum hose through there without too much drama. You have to unbolt the inner splash guard to get at this grommet, but that's not too hard either. If you haven't removed your AIVs, this would be a good time. However, if you have an auto, drilling a neat through the clutch master cylinder blanking plate is another way to go. Don't forget to seal it up properly using a tight grommet or similar.
it's for a greddy profec boost controller, the little head unit has a built in sensor so i had to. i ended up running it past the battery, no results yet coz i bought the wrong size hose for the wastegates, so it'll have to wait until tomorrow.
If its the evc displaying this, it would be from the units solinoid in the engine bay. Its not possible to have a leak before or arfter.. it is simpy a leak. Its like blowing up a balloon and saying one part has a different pressure from another part in the balloon, where its al the same pressure. If the unit is showing 9psi, then the manifold is at 9psi.. If you did have leaks in the pressurised parts and air was leaking out, once you fix the leaks, then the measured pressure should increase. Depending on the size of the leak.
