120 Volt varible Speed Motor for new EFI test/build bench?

[EagleMark]

Anyone got a suggestion for a plug in varible speed motor with enough power and RPM to drive 2 distribuotrs, probably off v belt and pulleys? Building a new test/build bench and want to have front and rear distributors mounted for when I build and test a system...

The idea is a 1/2 inch aluminum plate machined like an intake with all possible scenarios to mount TBI sensors grounds etc with small cap distributor on front and rear for differant engines, with drive under plate or bench to run system.

I have one dedicated bench for this with an intake but it's turning into a cobbled up mess and time for a remake. May also look for power supply for 12 volt side and do away with batterey, may add simulater to do away with vacuum pump.

So besides the varible speed motor any other ides for EFI system build bench?

A simple brushed motor and electronic speed control connected to a servo simulator would work fine, all connectd to your new 12V power supply.

Any one of these:

Or you could use most any small appliance motor and run it through a dimmer switch.

I use an older 120 VAC electric hand drill with an adapter to spin the distributor. The draw back to this setup is one of my hands is tied up when spinning the distributor, and the max rpm is about 3200. I'm sure there are second hand tool stores in your area? I've been thinking of cannibalizing a second hand electric drill, similar to mine, then add pulleys / belt to increase speed. I'm thinking some kind of variable rheostat to vary the motor speed. I think McMaster-Carr http://www.mcmaster.com/# has many options to look at.

Well I have a one speed drill hanging down side of bench and it has done well. But since I'm making plans for dual distributor so I can build the harness in place, run and test before install, this way has saved tons of time, everyone just works right first shot.

Hey I've got all sorts of left over RC car stuff! Was thinking of a servo for throttle position. I've got a remote for 3 way so I could run three servos or motors?

Looks like this will be a non functional RC Rock Crawler now...

Wonder if I could add a VSS to the distributor drives as well?

If it weren't for the purpose of building a harness and system on and then testing before install a simulator would be easier... but I need to build systems, but also like to have one available to check parts and funtion? hmmm... now I need 2...

For speed control, you could use foot pedals that are originally intended for domestic (non-commercial) sewing machines. I have one of these pedals kicking around that I know I'll come up with a use for one day. Originally I was using it for a variable speed Dremel, when the single speed Dremels were easy to come by and the variable speed versions were expensive.

I've found an Ohm meter to be a good quick tool for verifying pin outs of the harness. For simulation, I think all that would be needed would be the spinning the distributor reluctor (pole piece) for the distributor pickup coil to generate an AC signal for the distributor module. Sending an AC wave (about 1.2 volts) of different frequencies will trigger the ignition module for different RPM's. The VSS is also an AC Signal Generator. Maybe you can find an AC Signal Generator (Dual Output) for cheap?
