zrkie Posted May 11, 2011 Report Share Posted May 11, 2011 Heya guys! I’ve looked into Dcalternators to get a HO alternator. I’ll think about getting Dual brackets kit to run 2 alts including the stock alt. My ride is an Escalde 2003. 270XP : $599 (210A idle) 270SP: $449 (180A idle) 280PRO: $399 (160A idle) My system is: 3x batt (75Ah Running Bull AGM) all 0 gauge, 2x Rockford t20001bd at 2ohms, SoloX 18” I see most people get the 270XP. Is there any other significant difference between these alts than the idle output?? I hoped to use a dual alt setup, so maybe it is enough with the 270SP?? peace Quote Don't like sharing your knowledge? Welll.. Don't come here and grab others then! - GTFO.

RickyFriery97 Posted May 11, 2011 Report Share Posted May 11, 2011 mainly people get the XP for the high output at idle with the dual kit, either the 270XP, or 270SP will be fine Quote 2014 Chevy Silverado Crewcab 1994 Chevy Full Size blazer Link to comment Share on other sites More sharing options...
hdorre Posted May 11, 2011 Report Share Posted May 11, 2011 (edited) Shit, that XP is expensive! The XP has more idle voltage than DC's other lines. The dual SPs will be MORE than enough. Extra alt current isnt necessarily bad though. It limits/eliminates voltage drop.

hdorre Posted May 11, 2011 Report Share Posted May 11, 2011 He wants to run the stock alt with the dc power alt Not two dc alts Reading > me. With around 390amps of charging current when revving, im sure he'll still be fine. He may still be fine at idle with those 3 batts (if theyre really 75a and good).

JustinWilson Posted May 11, 2011 Report Share Posted May 11, 2011 I think with the dual alt, stock and any of those DC alts you would be fine. Do you plan to keep the stock alt for just vehicle functions like charging starting battery and maintaining, or do you plan to use both for vehicle and system use simultaneously.

Do you plan to keep the stock alt for just vehicle functions like charging starting battery and maintaining, or do you plan to use both for vehicle and system use simultaneously. I plan to run them together, not divided between audio and car function. He may still be fine at idle with those 3 batts (if theyre really 75a and good). It seems better to go for a HO alternator at this point than adding a few extra batteries.. Since this is for daily driving and not indoor demo's... The XP has more idle voltage than DC's other lines At least on paper there should be no difference between SP or XP series in output voltage; 14.8V. But experience >>> paper.

It seems better to go for a HO alternator at this point than adding a few extra batteries.. Since this is for daily driving and not indoor demo's... You misread my post. I meant that between the alts and batteries, you should be okay at idle. The XP has more idle voltage than DC's other lines At least on paper there should be no difference between SP or XP series in output voltage; 14.8V. But experience >>> paper. I thought the XP has a voltage regulator set to 15.1volts. I may be wrong, but im almost positive.

zrkie Posted May 11, 2011 Author Report Share Posted May 11, 2011 I guess they might put out 15.1v... I've seen that on youtube videos as the 'regular' resting voltage. I dunno if there are external VCU that easily fits to these alts? (url anyone?) Quote Don't like sharing your knowledge? Welll.. Don't come here and grab others then! - GTFO.

zrkie Posted May 17, 2011 Author Report Share Posted May 17, 2011 DC alternators sell the kits clearly stating how they would perform together with stock. I've never seen or heard about anyone on the forums who has done that. People always tend to go for as many XP's they can fit/afford. What would happen to the output voltage? The XP' seems to be put at 15.33, probably way higher than stock (and SP's too!). What kind of output do I get when mixing XP and stock? Plus, I was thinking to do 3 runs of 0 gauge (all positive?), that be enough right? Quote Don't like sharing your knowledge? Welll.. Don't come here and grab others then! - GTFO.
