A few Gauge Questions

[HParfitt]

Hi,

I finally got around to getting gauges. I decided to go with Isspro. Since I have a 6 spd I went with Pyrometer on an SRT-10 pillar, 60psi Boost on a Gauge Works single pod stering wheel mount. I am also going to do an engine Oil Temp and Fuel Pressure on an overhead. This weekend I got around to doing the cab work and running wires into the engine compartment. I'm slow. My questions are. Sorry for being long winded.





Ques 1:

The SRT-10 pillar does not have a lot of material to hold the Isspro gauge retainer. The tan powdercoated retainer that is affixed on the 2 brass posts. Actually I needed to turn the gauge sideways. Kind of good in a way since now I just need to watch for the needle to be straight up. Anything over that and I'm getting into the trouble zone. My question is looking at the SRT-10 pillar it appears that the Mopar gauge in the SRT-10 Ram must be mounted on some kind of shelf as opposed to a gauge clamp. There are 4 posts on the SRT-10 pillar near the gauge mount that are not on the stock pillar. What kind of gauge is in the SRT-10? Did anyone ever look into how the actual Mopar SRT-10 gauge mounts?



Ques 2:

I decided to use the Piers Boost Bolt. Everyone seems to recommend inside plenum bolts near the rear of the motor near the 4-5-6 cylinder. Looking at these bolts there seems to be a lot of injection hardware in that area. Has anyone used the first front inside intake bolt? Is there any reason not to use this one? It seems unobstructed and easy to get to.



Ques 3:

There appears to be 3 ports on the top of the Oil Filter housing. Would this be a good place to mount the sensor for engine oil temperature?. Would it provide a good indication of actual oil temp or is there a better place? Anybody have any ideas how long it takes to circulate the 12 quarts through the motor in a stock system? For exampe the oil pump flow 5 quarts per minute. I have no idea what the flow rate is.



Ques 4:

Does the stock oil pressure gauge give an accurate oil pressure reading? I hear a lot of people saying it's a glorified idiot light. Would it be worth while adding an additional gauge?. What I did notice. I was running Delvac 1300 for break-in. I recently switched to Delvac 1 at 10,250 miles. Actually the truck and suv since I can't seem to find Delvac 1 in my area. Anyway now that I am running a 5W-40 instead of the 15W-40 the gauge seems more responsive. Warm motor on the 15W-40 oil the gauge just seemed to hang at 40psi on a warm motor. A little under at idle a little over at speed. Leading me to believe the smart idiot light theory. Now the gauge seems much more responsive. Anyone else notice this.



As always thanks for all the reads and responses.

1. Ran into the same problem, I cut one of the legs off the bracket but left it so it still uses both posts to keep it from being able to turn. I put foam tape on the gauge housing so it was snug against the inside of the pillar cup, once the one leg was tightened up on the other side it is very secure, it has not moved and has stayed tight.



2. I have a picture in my reader rig of where I put the boost bolt, it is as far back as I could mount it, I did not want the capillary line going over the engine.



3. I used the center port for my oil temp probe, works great, reads about 215-220 degrees normal driving up to 230 degrees if towing or running sustained high RPM.



4. I have noticed similar things with the factory gauge, if it is just an idiot light as everyone says why does it read higher right after I change my oil? I can see it reading higher when it is very cold out as the truck "knows" the outside temp but there is no way it "knows" when I change the oil.
