Not sure what the differance is...

Boost and oil pressure..

 

Mech goes off like real situations (i.e. Your boost guage is a tube that goes from the guage to the vac source)

For ELEC. You have the same tube that goes to like a map sensor thing. Then the map sensor thing has wires coming off of it to the guage.

 

Mechanical needs a physical connection to the engine. Say for the oil pressure, you would have to run a line from the back of the gauge to the back of the block. With an electric you have a sending unit that screws into the block (or t fitting) and you run a wire from that to the gauge.

 

so whats better..is one usually more expensive then the other?

If you run a mechanical oil pressure or fuel pressure gauge inside the car not a single race sanctioning body will tech you in. Something happens to the gauge and you have ultra hot, high pressure oil, or flammable gasoline blowing all inside your cockpit. Mechanical is fine for boost, but try to get electric for most things.

Boost and oil pressure.. </TD></TR></TABLE>

the difference is.. the gauge is only as good as it is calibrated. either one can have correct/incorrect readings.

2 reasons to get electronic gauges:

1. with electronic gauges you have an option of peak/hold readings, because its impossible to always notice peak readings, and these would be the most vital
whats good is a gauge if you missed vital readings?

2. as mentioned already, hot oil lines and fuel isn't something you want inside your cabin in case of failure, even minor leaks will created a mess inside cabin you wouldn't have to worry if using electrical gauges. even boost gauge, a small vacuum leak can cause overboost, so why add more lines when there are better options for street car

 

Soooo electrical for oil/fuel and electrical would be better for boost but mechanical will work just not as good for crit readings ??

Please feel free to correct me lol...

 

Get electrical gauges for every thing except boost pressure. A machanical boost gauge is fine cause if a line broke inside the cabin it would only leak air. If a fuel or oil pressure line broke you'd have serious problems.

i'm reffering to peak-n-hold feature, it records highest reading so you can view it later and be aware. its possible to have same feature for mechanical, but i haven't seen anything like that on the market. other features are warning.. electronic boost controllers with LCD also have these features.

Those are really nice to have but they are really expensive. I dont feel like paying 250$ for a electric greddy gauge when I can pay 50$ for a greddy one. But I'm biased because I use my V-AFC for boost pressure play back and I LOVE it!!!!!

 

i use mechanical.. i use a steel braided hose. so i think i shall have no problem with oil being in my cockpit

Same here. No worries at all.

What's to stop you from being in an accident, rolling over, having the gauge ripped out of the a-pillar, and covering you in boiling hot oil? Nothing. That's why tracks won't tech you if you have a mech oil pressure gauge inside the car, they don't do it because they like being ********, they do it for YOUR safety.
