Unconfirmed: Better MPG on a budget

[raisor87]

I've been installing sound systems since 2005 out of my garage not a whole ton but a few a month. Anyway there is an audio electrical must when running a high output amp or several, and I just did it my my truck and noticed my MPG got considerably better for the money I spent. The only thing you have to do is replace your stock engine and battery grounding wires with some heavy gauge amp wire, as wall as your power wires from battery to alternator and starter while your at it. Basically the thicker wire and better than OEM connections to frame and engine block etc allows the electrical currents produced to flow more freely. I used 1/0 AWG street wires power wire for my project, and just some cheap copper ring connectors. You start at your battery take one wire at a time follow it to its final connection and replicate it using your new heavier wire, I usually go about 2" over the stock size if possible to allow the wire to flex. You can crimp your wires and connectors, or do it professional and solder them together simply with some flux, 60/40 leaded solder and a simple torch kit. I noticed about a 4 MPG improvement on my 98 350 vortec

So you made your own ground wire system. Cool. I've been wanting to do that. Many of them just add the extra wire along with the current wires.

Got pics?

I'm having a hard time believing that. How many tanks of gas have you ran through to come up with 4 mpg?

I've heard of mods along this line with the imports. The tout better MPG, better throttle response, etc. all due to better grounding and higher flow of current through key cables.

At the same time, I've always been kind of skeptical, but in today's economy if it's possible, it's worth a shot. How many tanks have you gone through with this? Also, can you load pics?

calculation came from trip from cincinnati to indianapolis I will load some pics soon as I get my camera back in a next friday

Still not believing it. You could have just gotten to good tank of gas. And here is my case in point. I rode my Harley from Pennsylvania to South Dakota, on average I get 175 miles per tank (5 gal). So I was filling up every 3 to 4 hours, now sometimes I'd put in 4.75 gals and sometimes I'd put in 4 gals. I'm just saying one tank of gas doesn't equal a 4mpg increase.

dont know I always use shell 93 octane I have to make this trip to indy each month so I know a very close average of how much gas I use I will keep you guys posted with future fill ups but the better grounding allows electrical components to their highest effeciency just like keeping your furnace clean at home

wow thats pretty cool how noticeable was the difference??

[apinechevy]

also do you have any pics of the install

[raisor87]

no difference as far as power that I can tell, but my headlights don't dim with my system turned up any more pics will be up this friday
