pontformulalt1 Posted April 8, 2013 Author Report Share Posted April 8, 2013 (edited) What exactly is the point of this? Lol Are you asking for help or showing? I wanted someone to confirm what I believed was belt slippageHow much load do you have on your alternator? Amps, fans, fuel pumps?5 amps totalling around 6k r.m.s. One red-top under hood and 3 kinetik 1400's in back. I clamped the car itself with the radio off and it pulls around 20-30 amps depending on if the cooling fans are on.I did some math I found and I'm not sure if this is accurate? 6,000 r.m.s./ .75 efficiency = 8,000/ 14.5 charging voltage=551amp draw + 40 amp draw for the vehicle itself. So almost a 600 amp draw at peak performance. Does this sound right? Edited April 8, 2013 by pontformulalt1 Quote Link to comment Share on other sites More sharing options...

A stock vehicle in most cases use about 60a alone. Sadly there are too many variables to give a "perfect" solution. Example max engine rpm, drive pulley, ohm load ect... I would try a larger diameter pulley and see if that helps.. Quote 1-888-MECHMAN www.Mechman.com [email protected] Link to comment Share on other sites More sharing options...

I am seriously considering an a/c delete with another 320a in its place. To even out the load. Would you happen to have any brackets for that? I'm guessing its going require me to do some custom fabrication myself. Quote Link to comment Share on other sites More sharing options...
Carbon Posted April 8, 2013 Report Share Posted April 8, 2013 if thats slippage than I'm fucked. My 320A is Covered in black dust Quote Link to comment Share on other sites More sharing options...

We can set those alternators up for a number of bracket locations. Feel free to call us if you do decide to make a bracket.

Kyblack76 Posted April 8, 2013 Report Share Posted April 8, 2013 What exactly is the point of this? Lol Are you asking for help or showing? I see what he is looking for.. that is the best belt wrap you can ever see also...

Kyblack76 Posted April 8, 2013 Report Share Posted April 8, 2013 When was the last time you put a new belt on? I put a brand new one on when I got my Mechman, and I think rocking.that.eclipse had slip until he put a new belt on also. Gates Green belts are preffered I believe, and it sure looks like you have plenty of wrap on it. Do agree... The first purchase was my HO alt ( not gonna say from who, it doesnt matter) and my second and third purchase was my bad ass GATES GREEN, and then, a new idler...

Peyton Cole Posted April 9, 2013 Report Share Posted April 9, 2013 Damn I got a new alt doesn't really matter who from and it slips for like 10seconds after I crank or less then stops it has a new belt half inch shorter then stock ima try and see what's up with my tensioner tomorow bad thing about my deal is if I did need a new tensioner which I doubt my car is so rare that I won't find it without going to dealership Quote Team CNGraphix 2013 sonata Dc power 320 alt 3 kinetik 3 shuriken All knue and sky high wiring Dd m3b x2 Rockford 1000-4 2 fi sp4 18 4 vo 6.5 4 nendo pwx8 6soundqubed tweets 2 b1 tweets Pioneer avh4500 hu Link to comment Share on other sites More sharing options...
HunterJohnson Posted April 9, 2013 Report Share Posted April 9, 2013 mine didnt work and I got a 3/8 smaller belt, now it doesnt slip. I wish I could have gone 1/2 inch but they didnt have it Quote Scion tC SQ BuildiPad mini, lots of fabrication, daily drivenFord Explorer C Pillar Wall Build Just a cheap car to destroy with bass Link to comment Share on other sites More sharing options...
