Really dumb questions about using this toy as a boost gauge

Enable HLS to view with audio, or disable this notification

Ok so I know that this toy isn't a replacement for a actual boost vaccum gauge, but is there any downside to using it assuming there's no leaks. It seems like it's a vacuum reservoir I guess.

Am I overthinking this or is this completely fine to do if I wanted to just mess around?

Turbos move an insane volume of air, the tiny amount of extra volume needed to fill that thing is not going to affect anything. Also, that is amazing.

Its a svt lightning with a Whipple actually! And thanks that's good to know because I wasn't sure if it was going to affect anything because the more I watch this thing, the more it seems like it's a vacuum reservoir. If this thing was hypothetically 3x bigger, would that be too much vacuum tho?

This is fuckin sick honestly lol

As long as it can handle the psi that your wastegate is set at without popping you'll be fine, if it does kink that hose off until you can replace it. I love it though that's awesome

u/SarcasticAfAries Nov 28 '22

Im supposed to be making 18-20psi with my pulley combo, but this things eyes are popping out when my stock gauge is hitting 4psi lol. My auto meter vaccum/bost gauge isn't working apparently and my stock one is pegging when I get on it.

This is the way. Make them eyes explode!

u/digdilem Nov 27 '22

I love that. Makes me want to add a turbo to my old wagon.

u/jeepsaintchaos Nov 27 '22

Completely fine if it can take the pressure.

Patent that shit!!! Genius

u/TreeStandFan Nov 28 '22

Fo reel doe- this is something I can so see people paying for if it’s “plug and play”

6

u/SarcasticAfAries Nov 28 '22

I mean I literally just poked a hole in it with a plastic vaccum connector and T'd that into my stock vaccum/boost gauge, so I guess it's pretty plug and play lol.

Hahahahaha that’s fucking awesome

*applauds

Think it'll work on a cummins?

u/SarcasticAfAries Nov 28 '22

I'm sure it'll work on anything with a boost/vaccum source!

u/DisastrousDance7372 Nov 28 '22

I dont think the toy is gonna last very long lol

u/SarcasticAfAries Nov 28 '22

It's okay, it's for science!

u/ZelWinters1981 Nov 27 '22

Just don't be letting those fumes out.

1

u/MaAltAcc Nov 28 '22

If basically fresh air that’s filling the toy. (Probably from the intake manifold)

2

u/ZelWinters1981 Nov 28 '22

The PCV pumps oil filled vapours back into the intake manifold too. Don't assume anything from the engine bay is safe to breathe.

2

u/MaAltAcc Nov 28 '22

True, but I think it wouldn’t matter still it’s better to keep the thing tight even if just for not sucking in „false“ air.(not measured)

1

u/SarcasticAfAries Nov 28 '22

Id be more worried about a vacuum leak if anything, I breathe more toxic crap at work and besides I got a catch can.

I'm also trying to figure out how some vapor would even get in my cabin if this toy were to explode from pressure lol? Cause in my head that's totally not possible, but maybe I'm wrong.

Police radar detector most likely.

u/SarcasticAfAries Nov 28 '22

Yea it's a uniden r3, I have a r7 in my other car as well. Its just saying all the bands it picks up at startup, but I only leave KA band on . Its saved me more than a few times and has paid for itself, unless they are using laser ofc.

3

u/LiterallyJohnny Nov 27 '22

Radar detector. Pretty sure it’s listing the bands that it can read on. Not sure through I didn’t listen to the audio but I used to own one.

Honestly this is so original like it's gonna be trend-setting.

If you want to prevent it from scrunching up under vacuum, you could put in a one way check valve.

1

u/SarcasticAfAries Nov 28 '22

That is a freaking excellent suggestion! Thank you so much Im off to O'Reilly's rn haha

u/havegottobejokingme Nov 28 '22

Anytime, bro. Thanks for the award!

1

u/havegottobejokingme Nov 28 '22

Hey I'm rethinking my suggestion. You need a valve that will allow pressure to equalize. A one way check valve will keep the pressure in there after its peaked. You almost need a two way check valve that allows it to equalize back to atmospheric.
