    Cam Lobe Design

    "For a fee you could get someone like Harvey Crane at cranecamdesign to design a profile." I don't think that will happen. This is just a model engine. "Try this guy he is real knowledgeable about cam design" I dont want to bother anyone off list. I am just looking for some basic...

    Cam Lobe Design

    I am in the process of designing a camshaft and need some help. When I increase the flank radius of the lobe, the positive G's go up and the negitive G's go down. I assume that the more positive G's, the more wear on the cam and stress on the valve train. Fewer Negitive G's and the spring...

    Volumetric Efficiency

    Even at 100 percent you are at 700 cfm. If you are racing i would put a 750 cfm For street use id go with the 650 cfm None of this based on scientific fact, just my personal experiance and opinion. I would like to here other opinions based on real testing.

    Using E85 for the hotrod?

    I did a search and found no thread related to ethanol or E85. I understand that ethanol and rubber are incompatible. The question was, what do i have to use to make my engine parts compatible, fuel lines, pump, tank, valve stem seals? Edelbrock makes a carb so that part is done. I could install...

    Using E85 for the hotrod?

    I am considering converting 2 of my "toy" cars to E85 use. I cant find any information as far as requirements for materials used. The first car has a stock 350 SB chevy engine. I hear Edelbrock now makes an E85 ready carb, so no problem there. What about fuel lines, pump, tank? Plan also...

    What is Medium Voltage?

    I believe the IEEE defines MV as 2001V - 69,000V

    How i am going to drying 18 medium voltage cable 20 kv

    In my area there is a conpany that test's breakers and cable. One of the services they offer is to hook up dry nitrogen to the cable to dry out a cable and push out the water. Call around in your area and see if any of your local testing outfits offer this service.

    MechE needs Elec.Cir advice

    Take a look at the Fluke 705 Loop Calibrator. It will do what you need but will no doubt be pricy!

    Arc Fault Calculations

    The truth about arc flash in the states is, there is no standard. Ask 5 engineers to calculate and you get 5 different answers. It has gotten to be a bunch of hocus pocus. Chrysler has new standards where 24volt control wiring is arc suit work because nobody can agree on what is needed. I agree...

    Can a 6-71support a 540 ci engine?

    The Weiand and the GMC 671,s displace 411 CID and the BDS blower displaces 390 CID. I have a 540 CID (4.5 bore - 4.25 stroke)with a BDS 8-71 (440 Cid) on it. At 18% overdrive she made 7Lbs boost and with a 25% overdrive she made 10.5 Lbs of boost. Im not sure and im sure someone will correct me...

    Automotive Air Filter Sizing/Flow Calculations

    Here are some formulas for K&N type filters. I believe these were found at the K&N website. Hope this helps. Area = (CID * RPM) / 20839 Area = (Height - .75) * (Diameter * 3.141593) Area = Length * Width Height = (Area / (Diameter * 3.141593)) + .75 Diameter = (Area / (Height - 0.75)) /...

    Grouping Neutrals?

    How does one know which red, black, blue is on a specific neutral if it is need a code requirement? YOU DON'T If the system was installed by a qualified electrician, the neutral should be properly marked at the neutral bus in the panel with all 3 numbers. Get a cheap amprobe and clip it on ALL...

    Button press using key stroke

    Hello ielivaz I have already done what you suggest and everything works fine. What i was wondering was, is there an easy way to make the button APPEAR to depress when the KEYBOARD is stroked. The rest of the code works fine, i was just trying to raise the visual coolness. If it's a big deal...

    Button press using key stroke

    I'm scratching out some code in VB6 and was wondering if anybody ever tried this? Can or has anyone been able to make a command button LOOK like it has been clicked when a key on the keyboard has been pressed? Say a command button on a calculator with the caption "1" appears to...

    3 phase transformer sizing

    There is no controversy!!! Just a difference of opinion. Both methods are acceptable and within the guidelines of the NEC. I just tend to over build a little more than the code book because i have cleaned up the mess after self proclaimed maintenance men who have never seen a code book work...

    3 phase transformer sizing

    I don't think 37.5 kVA is a standard size 3-phase unit. Siemans makes a 37.5 I agree with you that the installation is within the guidelines of the code book. Hey, smoke'em if ya got'em

    3 phase transformer sizing

    I guess i am just looking at it from the other end. I think you said you would use a 30Kva with the 100A main breaker panel. That is fine, Well within the guidelines but what if Joe maintenance loads the panel to 93 amps long after you are gone and the main holds on, Now there is a tranny...
