small performance battery?

[Rabbit on Roids]

yea, gas starters work well if you have between 7-10:1 compression, they dont work so well if you have 24:1 compression.

so is the power indicated on the "sticker" the max power required by the startermotor when first cranking (1700w) ?
it's to get an idea for cable sizing ...

sticker on the battery?
or sticker on the starter?

Cable Sizing? Just use a 0G and you will never have to worry about how much it can handle. I've seen them used to power 6500W sound systems. I'm sure the starter doesn't pull anymore than that. Even most big engines have like a 4G wire. To be safe Go Big Or Go Home.

8vof,

   My big truck runs 00g wires from the batteries to the starter. Also back on subject, you can get spiral cell batteries, but if you go that route, go with the brand name, not a house brand spiral cell.

has anyone ever tried a gas starter in a diesel? did they try starting a cold diesel with one? apparently not..
the gas starters are .7 hp, the diesel ones are 2.1 hp. thats 3 times the turning power... and probably pretty close to 3 times the amperage draw. why do you think powerjokes and cummins rigs have 2 batteries? they gotta have enough juice to get everything fired up.

There was a thread here a short time ago.. the guy could not start is IDI... turned out the problem was slow cranking because he had a gasser started w/ 1/3 the required power.

Exactly - some bosch reduction starters look like the vw diesel ones but are gutless, rated at about 1.2 kw only - you need at least 1.7 kw to spin the IDI mill - or get a modern TDI or mercedes CDI hybrid starter on it, it works amazing

are you referring to optima style batteries?

[Rabbit on Roids]

yes, some type of sealed gel spiral cell battery.

why dont you hook up a pull rope and bust out the spinach with some popeye arms to start it that way? no battery required as long as you have good compression   oh and don't forget to take the guts out of the stop solenoid... and then find a creative way to stop the engine.

i was actually looking at my buddies antique buick today that has a crank starter in the front and wood wheels, how about a nice big crank arm out the pass side? i have had a few vws that would only start with a bump start maybe ill go that route again....
