MECHMAN Posted August 7, 2008 Report Share Posted August 7, 2008 (edited) Sitting on my desk, I have a Large case conversion unit specially machined to bolt right on to 2.2 liter 4 cylinder equipped S-10 pickups, Cavaliers, and Sunfires. We tap the mounting ear, clearance the case, and inlclude the necessary adpter harness, so it installs in minutes. This unit is a 250 amp StreetBeater model, and has an outstanding low RPM power curve, as shown below on it's birth sheet. I include the 1/0 oversize ground and charge posts and the appropriate cable ends at no extra charge. This unit has also been built with the adjustable digital internal regulator, which is a $50 option. Weekly special price is $349 (normally $449) PRICE LOWERED TO $249 SHIPPED I can't hardly build these for that price!

Stephen Posted August 7, 2008 Report Share Posted August 7, 2008 what output could i expect at about 650 rpm on the motor? whats the range of the regulator? you can cook bacon shirtless if you're not a pussy...lol not hatin, but am i wrong here it looks as if the amp is not grounded its hooked directly to the battery. it that the way it should be.

n8ball2013 Posted August 7, 2008 Report Share Posted August 7, 2008 expect next to nothing actually. Our cars idle retarded low like that and the alternator doesnt actually kick on til around 8-900 rpms.

Stephen Posted August 7, 2008 Report Share Posted August 7, 2008 expect next to nothing actually. Our cars idle retarded low like that and the alternator doesnt actually kick on til around 8-900 rpms. thats alternator speed. are they the same? i would think the alternator would spin faster because of the tiny pulley. maybe im wrong you can cook bacon shirtless if you're not a pussy...lol not hatin, but am i wrong here it looks as if the amp is not grounded its hooked directly to the battery. it that the way it should be.

n8ball2013 Posted August 7, 2008 Report Share Posted August 7, 2008 dude didnt even look at the pics my bad im at awork and they dont show up. Im not sure if a smaller pulley would help or not.

Stephen Posted August 7, 2008 Report Share Posted August 7, 2008 dude didnt even look at the pics my bad im at awork and they dont show up. Im not sure if a smaller pulley would help or not. i was told the alt spins about 3 times faster than the motor. So according to the graph it would do about 100-110 at idle (700) you can cook bacon shirtless if you're not a pussy...lol not hatin, but am i wrong here it looks as if the amp is not grounded its hooked directly to the battery. it that the way it should be.

MECHMAN Posted August 7, 2008 Author Report Share Posted August 7, 2008 i was told the alt spins about 3 times faster than the motor. So according to the graph it would do about 100-110 at idle (700) The critical piece of information is the diameter of your crankshaft pulley. The RPM on the graph is rotor RPM, which is subject to the pulley ratio of the vehicle. For example: if your crank pulley is 6" in diameter, and the alt pulley is 2" in diameter, (6 divided by 2 = 3) you would have a 3:1 pulley ratio- the Rotor RPM would be 3 times the engine RPM. Because this unit is a large case that has been modified to fit, (rather than an "overwound" small case) it will have hands down the best LOW RPM output available, much stronger than your stock alt in fact. In addition, the digital regulator that we use (the red anodized heat sink on the back) has a much lower turn-on speed than a factory regulator, which also helps. If need be, I can install a 1.75" overdrive pulley on it, that would net you a 3.42:1 ratio with a 6" crank pulley. 650 idle RPM x 3.42 = 2288 rotor RPM = 142 amps, assuming a 6" crank pulley, which I believe is stock on an S10. 1-888-MECHMAN www.Mechman.com [email protected] Link to comment Share on other sites More sharing options...
