    Default Data Systems

    I've been thinking alot about getting a data system. I probably dont need one but right now i'm working on dialin the boat in and a few people have said things like "if we had a data system we could see.." I've also been wanting to see what my oil pressure is doing during a pass, after a pass, cruising, etc... A data system in this boat is always somthing that can be moved to my next boat so i think it may be worth the money. especially if i can catch somthing starting to go wrong before it goes really wrong. What do these units normally cost. At this point i'd like to just watch engine vitals (oil pres, oil temp, water temp, water pres, rpm) and pump pressures. I thought i remember reading some where that the sensors where what were really expensive. Anyway just want some thoughs and would like to hear what i will expect to pay. Anything else i should monitor?

    Shaun, give Jack a call. There's at least one of his setups up here and they look nice.......john

    Rpm, hi and lo suction pressure, bowl pressure, speed, oil pressure, fuel pressure are some of the most common. Sensors are $220 each. A six sensor system will run between close to 3k. Oil temp and water temp are nice but not on data. Have a regular gauge for those.

    I've bugged jack enough lately, i'll give him a call when i'm pretty much sure i'm going to get the system. Figured i could feel it out here first before talking his ear off

    Start here.....best of my knowledge still the best bang for the buck:

    Check on racingjunk.com or yellowbullet spam section you might be able to find one or better yet one of the other dragboat sites.

    Happy New Year

    Two that I have used at a little different ends of cost are Rack Pak and Innovate Motorsports.

    The Innovate Motorsports stuff is cheaper and you can buy any type of sensor you you can think of to measure pressure, volts, rpm, egt. The cost of their system is cheap but it is not the most rugged and has some downfalls.

    Race Pak is the most well know Automotive datalogging systems out there. They have a new Sportsman logger that is $895 I believe. It comes with RPM, Accel, volts, shaft speed. You add sensors to it from there by stacking the CAN cable.

    Either way you can get the into you need. We have a Innovate setup on my brothers boat and he is less than $500 into it.

    Brian,

    I am familiar with the Race pak but do you think it will do bowl and intake pressures?

    Personally I dont think Shaun would need anything like a 6 sensor system for what he wants to do right now.

    Shaun you could move some sensors around from pump to engine to get the data you need, 2 sensors to start would be okay then build up from there.

    Yeah your probably right. It is easy to change which ports you want to read. Its' easy to add more sensors later.

    Default digital VS analog

    I understand the difference between analog and digital signaling but what type of sensors would be digital? I would assume rpm, pressures, temps would be analog but what type of sensors would be digital, speed maybe? what else?

    RPM is the only thing that uses a digital channel for the majority of the guys with data in their jetboats. Most everything else is analog. You dont need to buy a sensor for RPM or voltage they are both freebies, atleast with a Quikdata they are.

    The way we do speed is through an analog channel and its measured off of water pressure with a pitot tube like a regular marine speedo. Some are using GPS or accelerometers, I don't have any experience with accelerometers but Im told they can be misleading The data systems we use have them we just dont use that feature and rely on the pitot tube data which is very useful. Ive tested alot of parts and thats the most important piece of data usually when testing.

    So far there has not been anything we could not find a way to record. The other cool thing is Rodger at Race Pak is always willing to listen and help figure out a way to make a new sensor or make one work that he has. How are you getting intake and bowl pressures? What kind of sensors?

    All the sensors that I'm using so far are pressure sensors or what are called pressure transducers. 12 VDC input. 1 - 5 v output. 3 wire.

    Bowl, hi and lo suction, speedo, oil pressure, fuel pressure, keel vacuum, crankcase vacuum, nitrous pressure. These are all analog sensors.

    Voltage, and RPM are digital I believe.

    RacePack certainly takes care of buisness, I am running race pack on new boat, product is excellent, service is excellent, Ive had them boys on the phone at midnight on race weekends getting help. Its pricey though
