A friend of mine's dad who has been a mechanic for many many years, happened to be around when i was planing to install boost gauge, still not entirely sure where to put it, he came over and told me it went here, a little port on top of my stock intercooler. it all worked excatly as he described (small dibit which i put a small drill into to break the seal, then attached the gauge using some small clamps and rubber tubing) the gauge seems to be working fine, it spikes at 9psi and settles around 7.5 - 8psi. i assumed this spot was meant for a boost gauge and alot of people were hooking it up here. but noticing that here on the forum it looks like no one else has hooked it up in this spot. since no one else had it hooked up here, i decided to post it, and see what people thought, maybe it isnt working correctly and maybe I should move it. I just wanted to hear some feedback and if anyone else had ever heard of hooking it up here?

hmm thats real interesting.... you know the only way to find out if its accurate is to move it to the normal location and see if it reads the same, if it does, well then thats some inovative s*** right there
 
yeah i could try it, but then i will have another line to seal, but where excatly should i hook it up. i know its a vac hose but you said most people hook it up on one right off the intake?? does anyone have a pic or somethin to show me.
 
well all ic cores have pressure drop then u wouldnt get an accurate reading, thats why they dont put it there im guessing.
 
maybe but in that case i'd be getting a lower than regular reading correct, im spiking at 9 psi and basically stock, i couldnt be boosting any higher than that, or shouldnt.
 
Seems like using a T on a vacume (sp) line is most stock looking. In addition a dealer could even give you s*** about making a hole in the IC. The IC is a lot more money to replace than a vacume hose. If you ever had a vacume problem, I bet they would point to that and say, "What the hell is that?"
 
no idea i was guessin. i just assume near the mani is best cause for one its a shorter line for the sample to get to the gauge (faster reaction), and secondly is exactly what the engines seeing.

the fitting is on the IC is already there stock. comes with a vac cap on it.
 
yeah the fitting is there, i didnt just drill into the ic, it would be very easy to seal and a number of ways to do it. at this point im gonna try to hook it up to a vac and see if i get the same reading. i guess my question is that does it have to be a specific vac hose i should be hookin up to or just one near the intake mani.
 
well there is some u dont want to tap into. u can use the one on the right top, it goes between 2 sensors, like a u kinda. its all alone, i used a t there.
 
and i guess pictures would be helpful if anyone has some of where to correctly hook it up cause i dont want another hole in a line without making sure it is correct
 
nice, that'l help, im gonna try and see if i get the same reading with it this way
 
yeah i just checked it out under my hood, i know exactly which hose to T off of. thanks for the help
 
I don't know about you other guys but spiking at 9 dropping down to 7 or 8 seems high to me. Just my 2 cents. Stock for me was about 6 sometimes getting to a hair over 7 in the cold weather.
 
depends on how the wg is adjusted. ive seen some at 8 psi. and a 1 psi spike isnt awful.
