Boost is the one time where there is absolutely no advantage whatsoever for having an electrical gauge. Of the half dozen Ive installed, none has been electrical.

This I would do. I lost all 4 quarts of oil from my engine into the cabin of my convertible when a compression fitting decided to fail.

My plan is an oil filter sandwich plate and an electric gauge

I bet it smelt like a gokart track for months good thing I love that smell jk ya I wouldn't want that pro sports electric gauges aren't much more then their mechanical so I'm probably gonna go ahead and get electric oil pressure mechanical boost and I have one more blank spot for a gauge soo what should I get is oil temp that important if I already have pressure any other gauges I should worry about got the wideband covered? Might end up throwing a volts gauge in there

Nope no smell. It all ended up between the subflooring and the body and drained right out the plugs

Wish I could give you some feed back on the prosports overall.

My sender just arrived back with them to be checked to see if it was bad .

How many gauges are in your car? And what are u using to hold them? I have 4 gauges right now in my NG900: Boost, A/F, Oil Temp, and Volts. I have the Elkparts dual a pillar pod and I had to custom make a gauge holder next to the cigarette lighter for the other two, but im interested in what you did seeing as I want to put a few more gauges in my car and I'm running out of room.

BTW, I had a friend use prosport gauges and he seems to like them very much and they havent given him any trouble yet. I was thinking on switching over from Autometer, but i like them too much.

I would only do electrical. At a minimum a peak recall feature is really handy to have. Plus, they're generally self calibrating, meaning that whatever atmospheric pressure you're at when you go through the start up sequence will be the zero so you won't have any type of offset.

So I'm not the only one .

Currently in the car: Prosport Volt and Boost, Autometer oil pressure

Waiting to go in the car: Prosport Oil pressure and temp, water temp, fuel pressure, EGT.

also if you order gauges from prosport you can use the coupon code fastspecv or crooked to get 10% off just a heads up


and also im going with a blue boost gauge to match my inovative wideband but for the oil press and volts down by the cigarette lighter should i go with green to match the interior or blue to match the rest of the gauges?

BTW, if you have a gauge in your headlight socket you won't be able to put the switch back in the socket and expect it to stay put. When you cut out that lip to put in a 52mm gauge you remove the part that holds the headlight switch. You'll need a new dash to replace it with.

If you have the base black dash in your I have a brand new one that I've been trying to sell. You can PM if you have an interest.

My lower gauges next to the cigarette lighter are green and they look great which led me to switch my other gauges to the same green color. I'm also looking into putting a three gauge pod on my dash for more gauges, i just dont know how they will look, but if you have any other ideas Id love to hear them.

I still say I wouldn't buy prosports again, since I can't dim that dang things and I do a lot of night driving with deer.

The big advantage for me with electrical is that I just put the sender over by the throttle body and ran the wires to join up with oil presser wires. Vacuum hoses for a gauge are just more hoses for leaks.

You can dim any gauge you want. Just buy a rheostat.

My Glowshift boost gauge is a searchlight right out of the box. An in-line dimmer brought it down to factory dash levels and it now dims quite well with the dash illumination dimmer.

just made my order for mechanical boost gauge im guessing i should be able to dim that one because ill just dim the power supply? and it wont affect how the gauge works and i also ordered oil press electric and voltmeter

I've always gone with mechanical boost gauges. From my experience, mechanical gauges generally gives you faster, more accurate readings.

However, with oil pressure I would go for an electrical so you don't have to worry about leaking oil into your cabin.
