    Need help designing a "one-off" DAQ system

    Hi, I'm not sure if I'm in the correct forum, if not please direct me in the right direction. For the past few years I have been pondering the idea of building my own DAQ system. This is not because I feel that existing DAQ systems are inferior, I simply have not seen anything that will do the...

    A Different Application For A Torque Converter

    PatPrimmer, Instead of oil I would use water. Cooling the water would be done close to the same as oil. The differences are fluid temp fluctuation and viscosity. Controlling a load against the torque of the engine will be done by providing a fluid port entrance at a strategic spot, and a...

    A Different Application For A Torque Converter

    Could anyone explain (to some degree of detail) why an automatic transmission torque converter could not be used in some capacity as a dynamometer brake. With the internal stator, impeller and turbine it looks like a possiblity. If there is a question as to why not simply buy a purpose built...

    Go-Kart Track

    Kiera1, Thr first question that needs to be asked is what is the intended use for this Go-Kart track? Will it be used for concession Karts (Amusement) or will be used for competition (Organized Racing Events)? If it is for Concession Karts, I suggest you visit...

    Wind tunnel application

    Matt00000, I appreciate it. However, I wasn't getting upset, by nature I get impatient to quickly when it comes to questions of judgement. I too apoligize. Actually, my line of questions were confusing. The questions were grouped together requesting answers on two completely seperate issues...

    Wind tunnel application

    In general, the rules are designed to make the performance of the karts competitive with each other, thus allowing the driver's talent to shine. As I said earlier, the fast classes require a rear wing and full body-work. Considering the major go-kart sanctioning bodies, there are thousands of...

    Wind tunnel application

    Octane boosters or any other oxygenated fuels are not allowed. Only spec fuels are used and policed by various testing procedures including spectrometer measurements. Regarding spliters they are not allowed however, in some classes wings are required. My original request for some help is not...

    Wind tunnel application

    Why does anybody put anything in a wind tunnel? Perhaps not known to a lot of people, go-kart racing is not what it was ten years ago. Looking for a competitive edge is what drives any form of motorsport and I don't believe go-kart racing is any different.

    Wind tunnel application

    A few years ago I purchased some items from a government auction. An item that was in one of the lots was a 21", 14 blade enclosed axial fan. The fan is cast magneseum or alum. On the fan housing it indicates 18,000 cfm. Initially, I had thought it may be a good size for testing...

    Welder Generator as a Dyno?

    Thank you very much for this information. I have no illusions regarding how labor intensive this project will be. For that reason, I will continue to further my information search in hopes to find an example that closely represents the dynamometer project I'm working on. However, I am...

    Welder Generator as a Dyno?

    I've been given 3 old welder generators (W/G), and I was told that they could be used as an "Electric Dynamometer" to measure I.C. S.I gas engines, specifically Moto-Cross (dirt bike)engines. Is this possible? And if so, beside the W/G, what else would I need to build one? The W/Gs are...
