low compression question

[Cummins12v]

how low can you go before its a pain to start without ether

 

[rockjeep73]

depends on how cold it gets where you live

If you have grid heaters and it doesn't get much below say 10 it's not much of an issue....mine is 15.5!

Need more info. All depends on climate, grid heaters, injector size, and timing. My 12 valve has about 15-1 comp, 27 degrees timing, ddp 140's, no grid heaters and likes ether below 60 degrees. It will start without a squirt at 50, but cranks for a while.
