BassJunkie Posted November 8, 2010 Report Share Posted November 8, 2010 Looking into getting d1400's with a vcm module. I'm just curious if my 2000 pontiac sunfires stock electrical could handle charging at 16 volts without frying the BCM, Instrument cluster, sensors, etc. Any reports of frying of such things?

TeejayBee Posted November 8, 2010 Report Share Posted November 8, 2010 no youll need a h/o alt for sure you wont be powering a 16v current off what 105a alt? and when you run 16v you do know you need to run a splitter for your regular car electronics because your car is usually okay up to 15.x volts but 16v its a no no i could be wrong but i think for daily driver i just summed that all up Quote Link to comment Share on other sites More sharing options...

BassJunkie Posted November 8, 2010 Author Report Share Posted November 8, 2010 (edited) Not worried about the alt in this scenario, more worried about other electronics. Seen a video of a gmc stock 105 amp alt and said it had 100,000 miles on it with the vcm and d1400 batteries. I of course want an HO alt to go with the vcm, but no point in buying a vcm alt and 14v batteries if its going to render my car useless two weeks down the road. I just like the idea of a higher voltage system in my car if I'm going to upgrade, if it can be done safely. edit: btw boilermaker...what part of ohio?

AMI CUSTOMS Posted November 8, 2010 Report Share Posted November 8, 2010 Suggested to go that high? NO, I wouldn't advise that, once you start to get that high with the voltage weird shit starts happening. I have had my walled sierra actually up to 16.2 with ZERO issues on a 12 volt system with the quad alts just to see how it would like it. It did fine. I did notice on other GM's and my truck that when you start to raise that voltage up over 16 volts, the main components that really doesn't like it is the fuel pump, on my truck that bitch was screaming. I have another competitor I know that ran 16 volts on his daily with zero issues. You are gonna charge anywhere from 2.2 - 2.9 higher then the base voltage(not rest voltage) of the system. Example, 12 volts you charge at 14.2 - 14.9, 14 volts at 16.2-16.9, and 16 volts at 18.2 - 18.9, you can go higher will all these, you may peak up to 19.5 on a 16 volt system for example, just know your battery limits. And yes the GM ecu has no problem with voltage in the 16 volts range, haven't tested past 16 volts, so I can't say if it is higher, I don't have to brass at the moment to brick my ecu yet.....LOL Quote TEAM SOUNDQUBED -- TEAM SOUTH TEAM S.O.B. - Founder & Captain 3x Streetbeat World Record Holder 2017 MWSPL 1st place Mayhem & 4th Xtreme 4 2016 MWSPL 1st place Mayhem/2nd Adv 4/2nd Xtreme 4 2015 MWSPL 2nd place Mayhem & 4th Xtreme 4 2014 USACI 2nd place Streetbeat 5 - 162.6 db 2014 MWSPL 2nd place Xtreme 4 - 144.9 db 2013 USACI 1st place Streetbeat 4 - 161.9 db 2013 USACI 1st place Street Q+ - 162.8 db 2013 MWSPL 3rd Kaos2 & 4th Xtreme 4 2011 USACI 2nd place MOD 1001-2k - 160.0 db 2011 MWSPL 4th place: Adv3 - 157.8 db, Kaos2 - 150s db, Xtreme4 - 140s db 2010 ARSPL 1st place 501-750 - 160.3 db Arkansas loudest Best score to date 164.4 db - Termlab Outlaw Streetbeat 4 - 161.9 db Streetbeat 5 - 162.6 db MWSPL on Dash Legal door open (Music) - 162.5 db Sealed on dash Legal (Music) - 161.1 db - Termlab THE BLACK NASTY CURRENT BUILD & FAB The Black Nasty (6) 15 Rebuild Log 2012 (4) 15 Walled Sierra Build Log Evo X build log Facebook page The Black Nasty Link to comment Share on other sites More sharing options...
AMI CUSTOMS Posted November 8, 2010 Report Share Posted November 8, 2010 Where's the answer then? Lets see where you research this stuff? I've looked before and NEVER found a REAL Technological answer from an expert. Just people giving their opinions on the subject... Not saying you aren't right, just wanna know where you get your info from... My testing and other people that have done it and I have seen the voltage read outs to confirm it was actually at said voltage confirmed by DMM. <<<<<Is that a run on, felt like it.
