Battery size?

[Knodty]

Hi Guys fitted the biggest battery I could find to see if it would help with the slow cranking when the engine is hot. Managed to get this beast in the Vette.
So far no problems which is good as it kept cutting out a few times when in drive. As I couldn’t get it to idle consistently at 850rpm in park.

How much was that mofo battery Pete?
I still get the hot start issues with mine sometimes......it usually re-starts after resting a couple of minutes.....I had thought about re-wiring battery to starter in significantly larger diameter cable to lower the load resistance (and matching the earth cable diameters too)

It was £105 from Shield batteries limited. It is a tight squeeze through the compartment Door and it is a touch higher. But with 830 cca it is well worth the money.

A high torque starter motor cures the hot cranking issues on a C3 and is smaller and lighter than the standard massive starter so suffers less from heat soak as it has more air gap around it . It also puts less drain on the battery and is a popular upgrade . I fitted one a few years ago and have been very impressed .

I have one of those mini starters fitted already.

Perhaps the mini-starter is OK for a small block and auto transmission - some big block manuals have different starter fixings. They can be a b'stard to shim-up correctly as you can't get to the reverse side of the starter pinion to measure 'gap'.......potential risk of damaging ring gear teeth.

I think it was a 096, I’ll check tomorrow
