** Alternator?

[Ryan1126]

I plan to put a 270 amp alt in my 2010 tahoe, but i remember someone saying something about a voltage regulator or something along those lines... Or am i just crazy? I believe they said i need to leave the stock alt, and buy a bracket to run them both at the same time to fix the problem.....is this true?

Wrong section bro, but no...most ** alts, ie, mechman, EA, DC etc, are internally regulated on voltage...you do have to buy a bracket, and keep the stock if you dont want to. You can get a factory replacement ** alt.

i had a feeling this was gonna be the wrong section.... Im looking to get a DC 270xp.... I can just do a direct swap? Cool saves me $300 for a dual alt bracket.

All DC Power 270XPs. One of them is for the stock OEM position, and is controlled by the ECM, so it won't always be at 14.9. The other three are on a separate harness and run at a straight 14.9.

how bad of voltage drops will i get with a 270 xp in the stock position?

Ryan which amplifiers are you using?

Also are you running any extra batteries? I used to run XS Power and they are beasts.

Impossible to tell, the ECM uses some complicated algorithm to adjust the voltage. If you have big subwoofer amplifiers power them with separate alts, only use the ECM-controlled alt for maybe a highs amp and other accessories.

Just curious, how long did it take you to get those alts? Nice setup and I'm just looking for one and DC is top on my list.

Im going to be running a sundown saz-2500 at .5 ohm and a sax 100.4. i will be running two XS batteries, both biggest i can fit under the hood. i dont want any batteries inside the car.

Well i went through mike singer for an alt and he said he can configure the alternator to basically bypass the ECM so i wont have to worry about it.

8 weeks. Running flawless since then, only a few minor install issues but that's to be expected with such a cutting-edge setup. Sickening power at idle, you will NOT get good idle performance from the simple rewound alts competitors offer.

That setup is nasty and 8 weeks ain't bad considering the setup is really out there. Trust me when I say I found out the hard way buying a competitors alt only to have a lagging idle output and basically rebuilding it every year. I spent the same as DC's top of the line XP on some BS but I'm going to have one soon. They seem to be in a league of their own with the XP series.

Hopefully the Beiber fans don't have them all busy after West Coast Customs did the custom CTS V w/ a DC 270 alt.....nah..but it was a cool looking alt.
