One of the reasons I switched to a CS144-normal output is 140 amp-is that my 120 amp OEM type alternator could not keep up with an idle high load situation. Generally speaking high amp 10/12SI alternators are not a good idea since they were never made to produce 100+amp outputs. The casing cooling is not great for that level of output and the components will eventually burn out. If you need a 10SI high output alternator for occasional high amp output, it will suffice. The CS144-140 amp alternator puts out 60 amps at idle!!

I am thinking about running two alternators…one for the engine and EFI stuff..and the other for the 900 watts of power my amp. is making pushing the two 8in subs and 2 sets of component speakers.

No need to-They sell CS144 alternators with 200/250 amps!!!! These alternators have excellent cooling for added capacity and you can get them with external rectifiers as well for added cooling.

That is correct the alternator has to be clocked for our cars and the place I bought my CS-144 did that before it was shipped.My shorty headers are ceramic coated-no issues. When I bought it a few years back, I recall it was $169/179 new-great alternator.Clocking your alternator yourself is not hard-just loosen and remove the casing bolts, slightly separate the 2 sides and turn to the desired position-not a big deal if you have to do it yourself.

Another question : how does the CS130 or CS144 work with tall valve covers and how close does the distributor get to them ? I have a space limited combo and the alternator currently is almost at the end of the adjustment outward.
