Decaf Posted March 1, 2012 Report Share Posted March 1, 2012 (edited) thanks for all the input guys, and decaf no he didn't. i would start with an overdrive pulley first. its cheap and "easy" to switch out. the same engine can be used on a 150mph car as a plow tractor... its about how where you want the output. the stock alt is a tractor, tons of output but slow and tops out fast. HO alt is a corvette, its crazy from 0-60, but let it open wide til over 150mph and it will drop your jaw Edited March 1, 2012 by Decaf Quote Link to comment Share on other sites More sharing options...
Mario928 Posted March 1, 2012 Report Share Posted March 1, 2012 Is there a way I can fix my idle output.

kickass audio Posted March 1, 2012 Report Share Posted March 1, 2012 IDK your engine but is it an electronic throttle body or is it a manual (cable driven) throttlebody? If its cable driven almost all engines ive tinkered with have a set screw on them near the butterfly opening to adjust how far open the throttle will remain when you are not depressing the gas pedal. Opening these up enough with your car in drive and getting the right idle speed to keep the alt charging will be your easiest bet. To do this id recommend getting a buddy to sit in your car holding the brake pedal down while dropping the car into gear while you are under the hood adjusting the set screw. Now if you cant find help heres what you can do. Get a brick and place it in front and in behind of your wheel to act as a wheel chuck and then test your emergency (parking) brake to see that it functions. Once you confirm it works roll down your driver side window as if there is an emergency or accident you can grab the keys and kill the ignition fast, find the set screw on your throttlebody if you have one, turn on your car and let it warm up for about 2 minutes and put it in drive with your parking brake engaged and wheel chucks in place. Now get a volt meter to help you see where your alt starts to charge at 14.4v and open up the screw on the throttle body until it gets the voltage up to that level. Once you have this change gears and put it in reverse (this usually isnt needed but while you are at it, might as well make sure you dont drop engine speed in any other gears but park and neutral) and test it. Once you have it like that ride it around the block and stop dead at a stop sign or red-light and see if your alt stops charging and adjust as needed.

Guest Posted March 1, 2012 Report Share Posted March 1, 2012 I thought messing with the idle screw is a bad idea Quote Link to comment Share on other sites More sharing options...

kickass audio Posted March 1, 2012 Report Share Posted March 1, 2012 Ive done it on my oldsmobile, my dads envoy and my moms impala and never had any problems. I have heard of people running into problems with it but mainly its the fuel consumption is increased because of it. Another thing you can do is change the size of your idler pulley if you have one on your engine. Those are super easy to change, just remove the belt, unscrew the bolt and bolt the new one on. Easy as that.

MECHMAN Posted March 2, 2012 Report Share Posted March 2, 2012 In many applications the idle speed is too low for the HO unit, an overdrive pulley can help in many cases. Quote 1-888-MECHMAN www.Mechman.com [email protected] Link to comment Share on other sites More sharing options...
