Boost Guage

Derk_eliso · #1 03-21-2007, 01:21 PM

I bought the Gloshift triple gauge pillar pods with the included tinted Boost, A/F and Oil Pressure gauges..

I lost the directions for my boost gauge and I was wondering if anyone knew how to install it...

There are 3 wires on the back and a nipple for a hose attachment. I know you T a vacuum line, and red = positive, black = ground... but there is an orange wire. Does anyone know what it connects to???

So theres 3 wires total?

Derk_eliso · #3 03-21-2007, 07:06 PM

correct, 3 wires and a nipple... I'm thinking that it might actually be for the dimmer??? because they're tinted, and they light up when the car is on...or are suppose to...

2nd question, which vacuum line should I use?

gloshift gauges are junk. Everyone sold out of our stores have been brought back. T- off the vac line from your FPR. i Have no clue what the orange wire is. Another reason i'll choose autometer, there are directions online in PDF format for every gauge they sell.

Hey Cody, i've called like every auto parts store in the 30 mile radius and no one has that clip for the injector... you think a hose clamp would work? it's just piece of metal the looks like a little C with a big C on top of it...

like if someone got bored and decided to do this..

I put a hairpin on the injector so that they were they same thickness, then put a hose clamp on it... The injector will not move, do you think it's safe to do this? lol...will it work?

Try it, once run the car see if it leaks. If its not leaking, then take it for a spin and really get on it so your in boost.. stop the car. Check to see if its leaking. if not, then your fine. You just don't want gas dripping onto a hot motor. Its going to make for a bad day and dangerous situation.

lol yeah.. well I tried to pull it out and I can't do it... it actually has a little less give then the ones that were put on right... hmm.. yeah and I can't start my car right now cuz my alternator is laying on the ground and my turbo isn't mounted, and I don't have my downpipe on there yet, lol... I will have my intercooler Monday, and the exhaust should go on Tuesday, we will tune it Friday, and I will be ready to go after that... I will check after we start tuning...

you have to run a few vaccuum lines when you turbo your car...the best thing to do is to buy a vaccuum manifold. You T into the vac line that leads to the brake booster BEFORE THE BACKFLOW VALVE! You're going to need to run vac lines to the BOV, Wastegate and your boost gauge....if you get the vac manifold, you can also T the FPR off of it...

that looks complicated, lol... I have a nipple off of my wastegate and one going into where the charge pipes connect. I appologize for my ignorance, but can someone educated me on those and the purposes, and what connects to, each other or something else... I'm sorry, but I am just not intellegent when it comes to vac lines... you're lots of help schister, but can you elaborate a bit more...

I have a boost gauge that I know I'll have to T for, and I have a boost controller... but aside from that and the actual turbo/wastegate what other vac lines are there?

Vac lines do the following:

BOV: The vac line keeps the bov shut during idle by creating negative pressure inside the bov diaphragm. During boost, the vac line transfers the boost to the diaphragm of the bov in order to keep it shut. There is a small spring inside the bov, but once the boost pressure overpowers it, it would open and leak if there was no assistance.

Wastegate: The vac line does basically the same function as it does to the bov because the two units are nearly identical parts. The difference however is that you can use a wastegate as a bov (in certain apps) but not the other way around because a BOV is not designed to withstand the heat. As with the bov though, the vac keeps the wastegate closed during idle and part throttle. Once boost is seen, it is transferred to the diaphragm in the gate. The diaphragm is designed to be an exact size so that the combination of the spring inside the wastegate and the boost pressure equal the desired boost level.

Hope that some of this helps....

yeah a little bit, I know the excess exhaust air flows through the wastegate because of the boost, it can't push all the air through the exhaust side so it goes through the wastegate and leaks out... I am a little bit confused because mine is internally wastegated, I can look where the exhaust gases come into through the manifold, and there is a slot for it to go though the turbo and another slot for it to bypass, then at the end of that "bypass chamber" we'll call it for now, lol... there is what I believe to be the blow off... a circle looking thing with a nipple at the top...

here this is easier...

have you heard anything good about SSBOV's? I bought generic intercooler piping. I know they won't fit and all that jazz, but I don't have any pipes at all, this way with pipes I can at least bend them and cut them to fit... so.... anyway this the pipes comes this...

SSQV BOV with intercooler piping:

Turbo Blow Off Valve SSQV style:
The Super Sequential Blowoff Valve (SSQV) Style is a dual stage pull type relief valve. Unlike other blow off valves that are push type, the SSQV will not leak under high boost conditions nor under vacuum at idle. Being of a pull type valve structure, the SSQV can not physically leak under any level of boost because boost pressure also keeps the valve closed against its seat
On typical blow-off valve designs, a large valve is utilized in order to accommodate high boost / high horsepower applications
The SSQV Style is constructed of polished billet aluminum, which ensures long-term durability and visual appeal. The mounting base utilizes a circular mounting flange that provides exception flow and complete secure mounting via a C-clip snap ring and O-ring gasket. The triple-fin discharge port design produces a powerful and unique aggressive blow-off sound along with added visual distinction.
Come with Adapter pipe (addition Reducer might needed to hook up pipe with piping kit.)

does anybody know how these work and if it would be better than my internal wastegate?... sigh. I love waiting til the late minute with everything...

Schister66 · #12 03-22-2007, 07:47 PM

hook the brass nipple on the compressor side to the port on the wastegate (part of the turbo)

Also, the SSQV is a good bov, but for my setup it is too small...since your turbo is a little smaller, the HKS one will work...

Does Autometer make tinted guages?

Derk_eliso · #14 03-23-2007, 12:36 PM

so since it's right in the piping, I don't need a vac tube to it... right? lol. and does it go on before of after the intercooler? does it matter? Thanks for all your help schister

chevboy · #15 03-23-2007, 07:38 PM

the orange wire is for your dimmer your right. You should hook it up to the side after the dimmer on your dimmer switch to do this on this car pull the top off the dash and then pop the fron fascia off of the dash and hook right up near the switch then it will illuminate for night when you turn your lights on, and wont unnessarily be lit all day long causing it to burn out faster. Yes autometer makes glow gauges i got them at the shop. I have a lot of injector clips i dont know where you are located but an easy bet and this is what i did is i got a ton at the scrap yard they are pretty much universal for gm. You shold really get one since if those wires are not clipped in perfect the car will run like shit and throw a code take five minutes at the pick and pull it will be worht your time.
