good to know. thanksI think you definitely should have a fuel pressure gauge if you have forced induction. Also an oil pressure gauge is good because the ones in are car is just a dummy switch that turns on at a certain amount of pressure. I like to know what my oil pressure really is. That being sad I have oil,fuel,temp,and air to fuel.
lolfuel level gauge is important. if you dont track your miles you may run out of gas and be stranded.
Since you have a A/F ratio gauge you don't need a fuel pressure gauge.as for the fuel pressure gauge, which one should i get? the one in water? or no?
That's some good info on the fuel pressure gaugeSince you have a A/F ratio gauge you don't need a fuel pressure gauge.
Personally, I think a fuel pressure gauge is useless on a returnless fuel system. If you datalog the computer you will see a constant 39-40 psi. That is the differential fuel pressure at the tip of the injector. That is not fuel pressure at the fuel rails and not what an aftermarket fuel pressure gauge will read. I have one. It jumps up and down from 30 psi at idle to 49 psi at 6000 rpm WOT.
There is a formula that you can use to calculate what the pressure in the rails should be. It's 39 psi minus vacuum/2 or 39 plus boost. I challenge you to calculate that as you are racing. But you can't even count on using that formula. On warm days I've see idle as high as 55 psi as the computer increases fuel pressure to prevent vapor lock in the fuel rails. An absolutely useless gauge.
I think all of the gauges in the dash are good except for the oil pressure gauge. You already have boost and A/F Ratio. You might add oil pressure. After that I'd go with oil temperature if you race a lot.
Only problem is that those gauges are too damn complicated to understand, especially while driving. I usually just stop like every 10 miles and put my oil dip stick in the gas tank and see how much fuel I have. Much more straightforward. Also I heard the little bit of oil that gets in the gas from that is good for the car.fuel level gauge is important. if you dont track your miles you may run out of gas and be stranded.

I had a Dodge with a gas gauge that didn't work. It averaged a whole 10 mpg. I carried two gallons of gas in my trunk just in case. On one cross-country trip I ran out of gas in the middle of the Nevada desert. I put the two gallons in and drove 50 mph hoping to see a gas station. I ran out of gas again about a quarter mile from a gas station. As I walked toward it with my can I just prayed it wasn't one of those that was closed and shuttered. It wasn't.fuel level gauge is important. if you dont track your miles you may run out of gas and be stranded.
