I talked with Kenny Bell just for reference and they say it cannot be done. I still have to wonder if the right valving can make this work. It really is just a matter of pressure spikes when chopping throttle and bypassing flow at idle so it is not boosting.

I am curious if this can be accurately done? Obviously we can determine the resistance in copper wire per diam, and determine over all resistance, BUT actually determining how many turns??? See, I think you can estimate how long the wire is but not how many turns. In sum, what I am trying to...

Thanks a bunch guys for the info. Due to design issue, modding or replacing the throttle body will not be an option but designing a separate bypass system or building it into a supercharger IS a possibility. In theory, it sounds like we just need something that will mechanically open at a...

In a custom application, we would prefer the instant performance that only a twin screw can offer. I have also not found much to support that a centrifugal type will really give any additional boost at peak rpm than the twin screw. (open to debate). Problem is we really need something that...

304 can be gummy. Raise coolant concentration to 10% or use dedicated fluid, and peck tap if you are going more than 1.5xD. Lube can be a MAJOR issue. If you are doing a blind hole with straight flute, good luck. I think most problems there can be solved with a good designed tap and better lube.

We are an aerospace mfg/eng group, not experienced with gears too much. We have a design (not aerospace) that will require some gears. Wondering if there are some references, charts, etc that would help us decide on a particular tooth cut for a given radius? Basically we have some 1" shafts...

Please, for example purposes, imagine a twin screw type compressor. We are making larger Al shafts and have to insert steel center shafts for the bearings on them. There are 2 of these running together and MUST be clocked together within a nats ass... Does anyone have any good ideas on how to...

Let me further add to the data and my questions here. A target engine is a twin cylinder 1.0L engine with a peak rpm around 8000. Problems are this is NOT a drag race only engine and more or less a closed course engine. It is important to get throttle response and part throttle performance as...

What rpm do you consider low??? Routers usually spin at 15K plus and usually more like 25K. I think I need to school up on universal motors but as I understand it, they can actually spin to the point of self destruct unless limiting is used. Also, I am sure for given designs, there are rpm...

LOL. We are going electric, not air but I agree, air would sing. Right now I am thinking about a circular saw motor. I can find the saws for nothing. Just wondering if they are a universal type motor.

My motor now gets so hot that I am sure if I put a meter on it, is pulling WAY more than plate and bogs out to nearly nothing... Certainly not "clutching" to maintain rpms. No balls... That is 500 watts but I am sure that is all of 200 actually going into the blades. I am just wondering...

OK, a bit of an off the wall question here. I am considering throwing a big motor in my blender for the heck of it. I want to find something used and cheap since this may not go all that well.. Target is 2HP min, 25K rpm. I am thinking AC/DC type motors since they usually have no rpm limit...

Have a few different applications but all will be higher rpm (6,000-11,000rpm) units. I really like the throttle response of screw but hear that centrifugal might have an edge for all our HP on top end. Can a properly designed and applied screw system be better than centrifugal? Design goals...

We are trying to make a DRO to display % concentration and PH of certain cutting fluids. I really have no idea what sensors we will even be looking for. We would want to build them from the bare component though. Does anyone have experience with this? FYI, the soluble oil is a unique oil...

In a nutshell, we have some machining fluids that need tight control of concentration. WE already have a nice circuit for an LED display but need to incorporate a way to sense concentration. Problem I see here is there is a variety of oils with slightly different SG ratings. I would also...

Thanks for the reply. I do understand that the DAQ cards will usually have some analog inputs and I understand that each sensor will have to be carefully selected and compared to the cards ability. However, my partner was mentioning an additional conditioner before the card to protect it. I...

Not necessarily looking for something for nothing but rather trying to see if there is anything else out there that can shave some time off our software build. We will need to automate our system so edit of source code will be important. I have found several basic DAQ packages around 500 bucks...

We are looking to use a DAQ card for a dynamometer project and many of the sensor inputs the the DAQ card will be analog. Mostly tach and temp and some inductive pickups from plug wires. Just curious when signal conditioning needs to be employed? Do we need the extra protection? Is that...

We are looking to build a dyno for a custom application and considering the use of Labview as the software. I have a friend that has Labview but rarely uses it or knows much about it. I am willing to get a seat if it will do what we need. For now, all we need to do is bring in approx 12...

Dido. I think we have finally put this one to bed and our math is correct. A lot of torque in 1st gear but the numbers do not lie.
