Engine on stand starting question

Mean416 said

My setup just uses a regular starter. What you're talking about you'd need a tremendous amount of torque from a motor. Think about the gear reduction of the spur gear to the ring gear in a starter motor. And a starter motor is a beast.

What you're talking about doing.... Quite frankly...its never gonna happen.

What I'm attempting to offer here is a couple basic bolt on parts that use the starter you already have, to let a guy verify stuff is working while it's on the build stand.

Anyway, you do you. Some people want everything to be special. My brother is like that lol.

You’re correct about the torque needed to start a fresh engine. Old D8 bull dozers use a gas driven motor as a “pony motor.” For starts before electric driven motors could handle it. Remember a starter does not care what end it turns over as long as it has the proper gear ratio it works. It got me thinking…I’m not trying to be special. I just do not want a run stand since most of my engines I have a professional machine shop with a dyno break them in for me. This is a stock 318 with a few items changed. I did not want to spend $1500 for the stand or $1450 for the dyno run if I can help it. Just another thing for my kids to dispose of when I pass.
But thank you for the sediment. I love to run things up the flag pole before I pull the trigger- if you know what I mean.
