    Any problems with using a hi amp alternator (say 140 amps) with relatively stock battery (around 700 cca)? I thought I read somewhere that if you upgrade your alternator you should upgrade the battery as well. The stock amp on mine is 94 amps, I think (94 A is what's stamped on the case). Any thoughts? I ask because a 94 A is about $150 here, and a Powermaster 140 A is right in that same range. Don't really need the extra amps, but for the same price, why not?

    You won't have any problems what so ever. The alternator will only put out as much power as is demanded. I got my 140 amp powermaster from Kpanza (aka Keith). Shot him a PM and he should be able to save you a few bucks.

    My only thoughts are, if its not broken, don't fix it, and secondly, if it is broken, a rebuild kit is about $15.

    If you aren't running anything additional electrical load wise that requires it, I don't see any point in going way beyond what you need. Just my opinion of course! : )
