Is it new or an old one as they have a great reputation for starting most engines from cold and have been used successfully on v8 engined cars too

I always assumed (probably wrongly!) turbo charged cars turned over easier due to them having a low compression ratio

Im not too clued up on the difference between cold starting amps etc but apparently it can supply 680amps for the first 5 seconds, its got enough grunt to get my st engine into life as quick as my old mahoosive bosch battery anyway

yep was new fully charged etc etc. it does turn it over but just not enough for it to catch. the saab needs 500cca standard holding current not peek, plus i have the draw of 4 stupidly power hungry vw sequential coils, megasquirt 3, 4 huge injectors, a pwm idle valve, etc etc

the vw coil packs alone can make the lights flicker in test mode on full chat as each one has a built in igniter. i did think it was the supply cables to the starter at first but after replacing them for stupidly big 10mm core cables it didnt make a difference.

i have had 2 offers for it within 2 mins of each other. ideally i would like to test it on another car before i let it go just to make sure it is ok. i would rather it go back to the place i got it from than it go to someone i know and not be fit for purpose.
