I would like to install a boost gauge in motorhome. I don't find hardly any guages listed for RVs since they are forty feet away from engine.
The gauges that you have do they run tubing all the way from engine to the front? I would think they would be slow to react to changes.
I have a Silverleaf but I think it calculates boost and is not an actual reading.

Yes, the VMSpc does calculate a few reading like hp, torque, EGT, however they use real data for intake air temp, psi boost, fuel burn, temps for oil, water, transmission, retarder plus many other important data that I feel gives me meaningful info. I like the Silverleaf data.

I installed a Banks 0-50 psi gauge in our 04 Essex. There are fitting up on intake to tap in which have plugs in which can be taken out to get your reading. There doesn't appear to be an lag time in the reading because when I step on the fuel the gauge starts reading right away. Would recommend getting gauge with at least 40 psi reading. Might want to also get an Exhaust Gas Temp EGT and then you will have both important diesel gauges. Both gauges came from Banks but I am sure other companies have them too.

On my last MH with Banks Stinger with EGT and boost gauge the Silverleaf and the Banks gauge were several psi off, I don't remember how much now but it was significant. I never knew which one to trust. The Banks guage was not a pressure direct gauge and got it info from the Banks Otomind.

Thanks Tom that is exactly what I wanted to know. I already have egt coming from Banks and I think I will get matching boost gauge also.
What size is the tubing to gauge?

DAJO I used 1/8 inch. Then I covered it with black plastic protector and used a lot of tie wraps. It can take some time to run it to the front and I think it was at least a 50 ft. run. Might get 55 feet so you aren't short. You will also have a long run on EGT and could both at the same time. I use the gauges a lot to judge engine performance. Just put the Essex on methanol/water injection and still working the jetting and methanol/water mix.

I installed the Banks IQ and Economind Diesel tuner. I did not install the separate boost and egt gages. I have my IQ set up to show them. I think that knowing what egts and boost you are running is probably the most important information you need. Both gages react quickly to changes. I did have to install the sensor for the egt gage. The boost comes off the computer the kit came with enough wirer to make the run on my 2003 38ft coach with a Cummins 5.9. It might be long enough for a 45 ft coach but I would talk to them on that.

Thanks Bill, I wish we had the large number of modifications that are available for ISB . There is not much available for the ISC common rail engine.

I don’t think there is that big of a need for a lot of moods. I have the Economind Diesel tuner and only run it on the number 2 position of 6 I have plenty of power. I didn’t feel that underpowered before I installed the tuner. I did have it on some good grades and no problems. The major benefit was in 6 fill ups in 2012 before installing the tuner and a Banks muffler I averaged 7.75 mpg. In 2013 I averaged 9.42 mpg for 18 fillups.

Tom, very interested in the Methanol/water injection, are you running it full time, or only on acceleration? What have you observed so far, as to power/economy? How big of a tank are you using, and how far is it going between fill-ups? Of all the performance mods/hop-ups, this sounded to me like the most logical, from a miles per gallon/ power stand point. The chips make power, but do so by using more fuel, seems as though the injection of Methanol/water is the right thing to do.

tom chelbana · 02-03-2014, 09:48 PM

GreaTOne65 I only use the methanol/water injection on 6plus% grades. There is at least 5 to 8 mph increase on these 6% grades. I have 2 tanks with a total of 13 gallons and am using a 25% methanol mix. I was only interested in staying in 5th gear around 58 to 60 mph on these 6plus% grades out here on the west coast. It did what I wanted to do for around 800$ and two days labor. Did a lot of extra things to make sure systems was safe. You can a lot of tuning with jets and mix. Using 2 jets .625 and .375 which works out to about a gallon a minute. The tanks are a problem with about 13 minutes of usage. I would say a lot of work but if you want up to 10 mph increase on 6plus% grades it does work. Tom

GreaTOne65 · 02-04-2014, 08:31 PM

Which system are you using, Tom? I had been investigating into a system, but at the moment, my resources are strained. They had said, that using plain water, continuously, showed improvement in mileage. I had thought about putting a Tee, in a line from the fresh water tank, and using a electronic solenoid to switch back and forth, save the methanol mix, for the hard pulls. Very interesting what you have observed, on the power side.

tom chelbana · 02-05-2014, 10:03 AM

We are using the Snow system. They are good with questions. That's and idea I hadn't thought about using a solenoid to switch between two different usages. The problem I see is you would also need to have two different hoses and jets because to get the power you need to use a lot of jetting but to use on the open road you would want less jetting so you wouldn't use so much water. I did also find that the methanol/water injection does a good job of cleaning intake and the top of the piston.When I contacted Snow they said they have users who use to have EGR problems and once they went with M/W injection no EGR problems. Still a lot to find with the system. Tom
