    Gallons Per Minute based on Engine Displacement

    patprimmer, pontiacjack, I found an interesting web sight that provides a tune up calculator that will give you a complete baseline fuel system set up. Fuel Injection Enterprises is the name of the company. www.fuelinjectionent.com Tells you everything you need to know and eliminates the need...

    Gallons Per Minute based on Engine Displacement

    pontiacjack, The original GM Detroit 71 series diesel engine drove the roots type air pump at 1:1 crankshaft speed. That resulted in the air induction being slightly higher than atmosphereic pressure. In later years the 71 series engine was offered in a turbocharged version. However the roots...

    Gallons Per Minute based on Engine Displacement

    patprimmer, pontiacjack, Several of the old mechanical fuel injection companies are moving to electronical systems, but they are extremely expensive. There's a fellow in Canada that's converting old mechanical fuel injection systems to EFI and his price is more affordable. I will probably...

    Gallons Per Minute based on Engine Displacement

    Pat, Another very good point. I had not considered the volume of the blower. I will call Don Hampton and get an exact number. My engine is 400ci and I'm using Air Flow Research 23 degree heads and they will flow 350 CFM @.750 lift. Thanks, Ron

    Gallons Per Minute based on Engine Displacement

    To All, Back in the late 70's I ran a blown alcohol 364ci small block Chevrolet in Pro Comp dragster. My career best was 6.29 @226 mph. I always consider myself to be capable of a good tuneup. Back then I was young and lived for nothing other than drag racing. When it came time to purchase the...

    Gallons Per Minute based on Engine Displacement

    Pat, Thank you for your input. I had done some research in an effort to factor by weight, but the weight of 1 cubic foot of air was something like 0.0807 lbs. Air is a rather ambigous gas so I was uncertain as to whether you take it at face value or break it down to oxygen content. 1,600,000 /...

    Gallons Per Minute based on Engine Displacement

    Hello, I'm trying to calculate the GPH of fuel required to maintain a 6.5:1 Air to Fuel ratio. My engine displaces 400 cubic inches, but being a 4 cycle it actually pumps 200 cubic inches per revolution. The engine will operate at a maximum RPM of 8000. 200 * 8000 = 1,600,000 cubic inches...

    Opening Files

    JAB1961, Ctrl+Alt+Delete will open the Windows Task Manager. Select the Performance tab and then open a file that is known to open slowly. Watch the CPU usage in the Task Manager. If the CPU usage is high then shut down any firewall and anti virus programs and then re-open the same file. If CPU...

    Protocol for Interface Between Laptop & Docking Station

    Hello, I have an application that I would like to use an external expansion buss similar to a Magma expansion chassis, but very dissimilar to their price. There is an abundance of new & unused laptop docking stations and several of the earlier units facilitate both ISA and PCI expansion. My...

    Disassembling a Permanent Magnet Motor +

    Stardelta, Does the metal slug need to be the same diameter as the armature and how much time does one have to insert the slug? I'm working on a motor that cost $1,800.00 so I'm slowly proceding with caution. Servo

    Disassembling a Permanent Magnet Motor +

    Stardelta, Your statement regarding the reduction of the shaft size is true however my application does not lend itself to an alternate solution. The motor shaft fits into a gear box and the shaft receiver is harder than my head. Servo

    Disassembling a Permanent Magnet Motor +

    Hello, I have a 2HP AC permanent magnet motor and I need to remove the armature so that I can reduce the shaft diameter. I was prepared for a battle due to experiences with smaller motors but I under estimated this task. What is the proper method for removing the armature so as to prevent...

    Inverse use of a Transformer

    Hey Guy's, Thanks for all of the input. I went into this project with very little knowledge, if any, for what I was wanting to accomplish. I soon learned that 12/24 does not always, if ever, refer to the actual secondary current. The balance of the knowledge came soon after. Beyond that I all...

    Boost Transformer and Line Reactor

    Hello, Along with modifying the voltage does a boost transformer in effect accomplish the same task as a line reactor? Servo

    Inverse use of a Transformer

    Thanks Guys, I have not purchased the GE transfomer so I've not lost any money. Due to your replys I believe that I'll search for another solution. Servo

    Inverse use of a Transformer

    Hello, I wish to thank all of you for your input. I was in error when I reference the ratings for the transformer and my application. The GE model 9T24C401 transformer is rated at 75kVA and my application requires 2.2kVA. The transformer taps are as follows: HV=192--222; 318--526, LV=120 or...

    Inverse use of a Transformer

    Hello, I have a 3 phase "step down" transformer that has multiple HV inputs and two LV outputs. My need is to raise 208/220 up to 230. Mathmatically I can accomplish that by reversing the roles of the HV inputs and LV outputs but I do not possess the knowledge to know whether or not that is...
