Is there any other company that make rail pressure guages other than dipricol? I have been reading threads all afternoon and the is the only company i see mentioned. And they are proud of there stuff.

 

they are the only ones worth the $$$ tho IMHO...... think of it as a diagnoses tool and a tuning tool

 

Quadzilla Commander reads pressure but it's not cheap either. The benefit to it, is that it will do a lot more than read rail pressure.

The only other option I've heard of is John at Floor It had a custom one made before the DiProcal was available. It will read 40,000psi. Of course, it cost him $1500. Makes $300 not sound as bad.

 

iI already have the attitude so i hate to step up to the commander. i dont mind paying for the rail gauge but i want matching gauges and i like the phantom II

 

The DiPricol RP gauge is really an excellent investment if you plan to ever install fueling mods beyond the basic idiot-proof levels.

 

I have had mine in for about a week now and am pleased thus far.

 

Mine's gone bad already. I was up at Floor-it over the weekend for other reasons, but the gauge always read high. Since then I've been looking at the SPA gauges. They have a modified one that will read rail pressure. John told me they were the original rail pressure gauge. It's not analog though.

 

Diablo predator reads pressure plus a whole lot more. It reads it in Mpa so you have to multiply to get psi.

 

Mine too. I should have a replacement this week. Mine was reading low though.

 

oma, how did you confirm your gauge was shot? I'm having trouble with mine reading low.
Initial start up reads 7k~, seconds later needle drops to 3k~ or less, notice driving the needle will go up and down even when the load has not changed???

I have a new one coming but have no solid evidence that the gauge is faulty.

 

Did you just order a new one and going to pay for it?

That's exactly what mine was doing. It would read normal for a little while and then fall off. On a long haul on the highway it was down to zero. Obviously my pressure wasn't zero or the truck wouldn't be running. I hooked up my Diablosport and wernt into the live data menu and drove around watching the pressure with it, and it was normal.

I don't have the info with me right now, but I'll get you the names and numbers of who you need to contact so you can return the faulty one for credit - hopefully I'll remember tonight after work. (code for - I'm playing on the internet right now at work) I don't have my replacement installed yet, but hopefully it isn't the same way.

 

Does y'alls' RPM change when the RP gauge surges?

 

How would you guys feel about a very inexpenisve but, nice rail pressure only gauge?

Or would it be better to have a gauge that read rail and lift pump pressure?

 

great! wanna a gineau pig truck quad?

 

all joking aside. could you give some more info? such as method of connection, does it plug into a quad race module, diameter, color. etc? i am in the market for one quite soon. thanks
