ha haaaaa, i knew it, and yes dom did recommend something alongthose lines for my car //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

thanks for the input guys

GO CHEVY GO!!!!!!!! lol

the power curve of the alt becomes steeper with the higher output

and dont take ur car to autozone to get it tested because those idiots barely know how to put on windshield wipers //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

check this thread out about how to test a ho alt from dominick himself

Call me crazy, but I didn't see anything about how to actually test it, just why you shouldn't have them test it there.

under hometown rebuilder there is how it is tested incorrectly, u can see correctly how to do it by how they do it INCORRECTLy //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

But I don't want to have to think about it... nor do I want to have to think about how to load down 400 rated amps worth of alternators.

Low-speed charging amperage depends on several things:

1) What pulley is installed... it's possible to put a larger crank pulley and/or smaller alternator pulley, to make the alternator spin faster

2) The rotor and stator design... the more "poles (individual windings) are in there, the more times the rotor "breaks the flux lines" and the more charge cycles you get, per rotation of the engine.

3) how the rotor is energized. It's possible to use GREATER THAN 12V to drive the rotor... this will increase the magnetic field, and the charging current. You have to know what you're doing, as far as powering the rotor field (getting the right flux current vs. RPM vs. load curve), but it can make things happen at VERY low speeds.

Doing these things, it's quite possible to make an alternator that will deliver lots of current at idle... I know, I helped DESIGN the first version of the product these folks sell, back in 1991-1992:

Here's a test, from Car Stereo Review, that VERIFIES that the alternator (in this case, a 200 amp) delivered 70 percent of max output (140 amp), at 1000 RPM idle speed:

So, yeah, it's possible. It's not going to happen from some random parts slapped together by an auto parts store... it's not cheap to make it work, but it CAN happen.

Gordon.
