Anyone thought or have installed a boost gauge yet? I found one laying around the garage and thought it may be nice to know exactly what were pushing. Question is, where to mount it..

I am going to be making an insert "plate" of sorts so you can do this exact thing. Still a few weeks out though.

If you can't wait for that, you will have to splice into a vacuum line coming off the intake manifold.

Does OBDII happen to report boost pressure? Just curious as to wether that could be an option. Guessing it might not report that back though.

It depends on the device you plug in to it. Most new ones will recognize that parameter. I plan on using something like this very soon.

6thElementEngineering, the gauge I have came with a "T" to splice into a vacuum line. What type of plate are you manufacturing?

I'm going to be using an OBDII Bluetooth reader for mine.

I am going to make a plate that goes in between the factory MAP sensor and the intake manifold. It will have a couple ports so you can have a dedicated boost signla source for things like a boost gauge and Blow of valve. It will come with plugs and small fittings to hook hoses up to. That way you don;t have to cut any factory lines. Plus it will look cool too

Sounds good. I installed my gauge today. I couldn't wait

. However it is somewhat temporary. Ill post pictures here soon. Came out good.

was the sender hooked up when you took the last picture?

At idle, the car should be pulling -15 to -21 in/hg. I see that gauge at 0.

Which line did you tap?

Let us know what kind of PSI you're seeing at full throttle when you get the chance.... Apparently according to the velosters, they ae pushing 18PSI stock. I wouldn't think it would be set that high....i guess unless they were wanting to push the turbo (not to the extreme) to set the HP at 201.

I did have the vac line hooked Up in the picture. However, I have not been able to find and adequate vac line yet. The ones I've tried either pull vacuum and no boost, or boost with no vacuum. But with boost showing, the gauge showed 16psi. Now how accurate that is I'm not sure just because I haven't found a perfect vac line yet. It doesn't seem to have the same hook ups as the VT's from what I've found but I could be missing something. It is currently tapped in to the wastegate vac line into a solenoid.

Yea, if you have that installed using a line off the wastegate or turbo you're gonna have a bad time.

Best place is a line coming off the intake manifold or charge pipe between the manifold and intercooler. You will get full range reading from that. I saw on veloster forums they use a vac line coming off the throttle body. That could be an option for you until I can get this plate to market.

That was my next try would be the throttle body vac line. I cant seem to find many lines off the manifold in these cars. A mechanic at my work mentioned trying of the MAP sensor.

Yea, that's where my adapter plate will be going. The map sensor is directly bolted to the manifold. You won't have a line from that you can tap into.

Right now, I'll just leave as it is. It shows boost just no vac. I'll wait till you get that adapter plate out to us...

I thought about getting one of the small LED numbered units, just so it blends in alittle more.... only issue is the cost... I think they are around 150$
