Sheena Posted August 12, 2012 Report Posted August 12, 2012 so a few of us honda guys got to talkin in pm and in our little thread about when our belts would start slipping. basically what we want to know is since DC power makes a 270 amp alt for our vehicle and no one else on the market even comes close.. would our belts slip on their 250 amp and 270 amp units? if no load is applied at idle then the load is applied at 2-3k rpm would we still get belt slip? if we rolled into the volume knob would the belt slip not be a factor?

crunkjuice1 Posted August 12, 2012 Report Posted August 12, 2012 I would assume the the actual amount of belt wrap on pulley is the main player with slip regardless of company. Quote
n8ball2013 Posted August 12, 2012 Report Posted August 12, 2012 correct belt wrap is the key. All of us chevy guys with multi alts get slippage Quote THERE IS NO BUILD LOG! 1998 Chevy Silverado ext cab Alpine CDA-9887 4 Team Fi 15s 2 Ampere Audio TFE 8.0 2 Ampere Audio 150.4 3 Digital Designs CS6.5 component sets Dual Mechman 370XP Elite alternators inbound! 8 XS Power d3400 6 XS power d680 Second Skin Stinger Tsunami Wiring Sky High A Real Voltmeter not a piece of shit stinger.
C-Fizzy Posted August 12, 2012 Report Posted August 12, 2012 You should be fine tho. when I had a 270 on my Toyota 2.2l I had belt slip, then I tightened up the alt correctly and I never had a problem after.

Sheena Posted August 12, 2012 Author Report Posted August 12, 2012 Can you define belt wrap for me? I just want a full answer and not have any more questions about belt slip lol. Basically just make sure it has the proper tension on it?

Maebros Posted August 12, 2012 Report Posted August 12, 2012 But doesn't the slippage hinder the output amperage of the alt. So wouldn't having a lot of slip defeat the purpose of having an the 270 over say some of the smaller ones Quote HU: Pioneer AVH x5800BHS SP Amp: AQ 120.4 Front SP: Hertz Hsk 165 Rear SP: DD cxs 6.5 SW Amp: Crescendo BC2000d SW 2 DC level 3 12" Electrical: Stock alt for now XS D2400 XS D3400 Knukonceptz Kolossus Second skin damplifier On 8/8/2012 at 4:50 PM, Brandon15zzz said: I heard he actually graduated college with a 4.0 gpa.

So wouldn't having a lot of slip defeat the purpose of having an the 270 over say some of the smaller ones yes this was the question raised in our discussion. with the proper tension on the belt, would a 270 amp alt be too hard for a 650 rpm 1.8L engine to turn properly?

Real96SS Posted August 12, 2012 Report Posted August 12, 2012 I have a triple DC Power alt setup on my Avalanche and have never had belt slip. I don't think it has anything to do with which company you use but like everyone is saying the belt wrap.

Tarball Posted August 12, 2012 Report Posted August 12, 2012 define belt wrap. I believe belt wrap is the percentage of the pully the the belt actually comes in contact with. This contact introduces friction. Less area with pully/belt contact = less friction = gretaer chance of belt slip. More area with pully/belt contact = more friction = lesser chance of belt slip. The above assumes a properly fit belt and a good working tensioner if applicable. 1 Quote CURRENT SYSTEM: Alternator: Stock alt on mids/highs Isolated DC Power 270 SP - Charging @ 16.8v Batteries: (2) XS D1400s Power Cable: Double Runs of 1/0 KNU Kolossus Fleks Headunit: 80-PRS Sub Amp: DC 5.0k Subwoofers: 2 RE MT 15s /PSI dual .7ohm recones Subwoofer Enclosure: 9.1cubes @ 32hz - brutal.
