Is there absolutely no way to get a reliable boost/vacuum source (for an aftermarket boost gauge) on the Exige S other than having to drill and tap into the intercooler (outlet) pipe?
Can those of who have fitted a boost gauge share some pics of how and where they tapped for the boost source?
I hunted high and low at all the pipes I could physicaly get at, I did not manage to find one, I got Proalloy to weld a bung into the pipe from the intercooler to the inlet manifold as I wanted to see boost after charge cooling. Good luck if you do find one tell all
Ade, can you please post some pics on where exactly you drilled and tap your intercooler pipe? And I assume you had to use some kind of an adaptor to connect the nylon/silicone hose to the welded bung?
Is there not a vacuum line from the brake servo that we can T-off?
Hi Hackzi, sorry for the delay in replying to your PM.
After Ade told me there was no souce (which I agree with)
I drilled and tapped the high pressure side aftercooler pipe. Then fitted a 1/8 male threaded bung, with a rubber cap to seal it once id finished using it for the dyno.
If you open the boot and look inwards, its the left hand aftercooler pipe.
Doesn’t really matter where you drill, but I went for a place on a straight section, and pointing towards the rear window.
If it’s just for a boost gauge I personally wouldnt bother as there is little point in a boost gauge on a supercharged car - but if it’s for dyno testing then that may be worth while.
If you do drill and tap like I did, just ensure it’s really clean afterwards (blow it out with air) and use some thread lock on the fitting.
I cant get you a pic of mine for a couple of weeks unfortunately.
I tried using the vac hoses from the air idle solenoid but these do not see +ve pressure.
