    Occasional drop in overall voltage

    As Sunlit mentioned, definitely check those connections. Personally, I would go through all the connections and CLEAN the surfaces....all of those grounds have paint under them, don't be shy with scraping some of the paint away and putting a little electrical grease on them. One connection...

    anyone do E-fans on a obs??

    Wow, that's cheap on that efan!! If that thing can pull serious CFM and the motor in NOT from China, looks like a really sweet deal! (see if you can find out the manuf on the motor and some other specs) I think Siemens makes the Mark VIII motor and durability has been rated high (the reason I...

    3/4t rear - ??

    I'm at the beginning stage of learning about the 1/2t to 3/4t 6lug swap. Would this fit my 4dr Tahoe?? Why makes this a "Posi Locker" but another identical rig did not have the "posi" Next question, anyone traveling from FL to DE/NJ/NY/MA anytime soon?? :)

    Ported Throttle Body

    has anyone measured the actual mpg improvement or lack thereof? (no guesses pls) Also, the bump for improved acceleration...why would this ported TB improve acceleration? Does it improve midrange? I have a BB tune, would it need to be re-tuned? (I'm a newb, still learning) Thanks guys!!

    HORN Question

    do this..sounds great Easy install and I wired it directly to my primary so it works OEM. Nice 300hz (low freq) with a bit of kick to wake up the world, but not obnoxious.

    anyone do E-fans on a obs??

    A guru...we've lowered the bar :) Personally I won't mod a truck prior to driving it that far as edzaar mentioned...especially with an electrical install on a critical component. If one relay is bad or the fuse blows, (or the fan motor goes) it could cause you some real pain. With the other...

    anyone do E-fans on a obs??

    There's a few write-ups online...now go buy the other parts to support that relay :Plugged: #268 (i'm guessing we hit 300 now that this Vovlo part was purchased....a bit more technical then a simply relay) check this out...i didn't read it all the way so i can't vouch for accuracy, but...

    New Rough Country 3.5" Suspension Lift

    Chevydawg - before you install, definitely check other forums for this specific lift and if you start seeing similiar user experience for your NNBS, return it before you install it. This kit may be great for your rig and all these warnings an overreaction due to their other kits....but...

    diffrence between 4" and 6"

    Did you install that or have a shop do it? If you used a shop, what did it end up running you for the install? This is more of a technical question, but I'm going to convert my 1/2t suspension parts to 3/4t, any idea if the Dick Cepek suspension kit designed for a Tahoe would still work or...

    small lift

    I have a 1.5" block in the back...and cranked 1.5 - 1.75" in the front to level it out. (looks great in person) My 285's fit nicely but when the front is compressed, it doesn't take much for the tire to hit the fender...I can turn the wheel lock to lock w/o it rubbing...but with a 5" BS, it...

    New Rough Country 3.5" Suspension Lift

    Check the OBS forum...there is a sticky at the top that aligns with Matt's comments. It may not hold true with your NNBS, but something to consider.

    Cold Air Intake tips.(hope this helps)

    Just out of curiosity, how did you come up with those 0-60 times? What engine mods? I really hate to call this one out...but knocking off almost a second on your 0-60 times JUST by installing a different air intake is tough to stomach. Unless there was something seriously wrong with your...

    anyone do E-fans on a obs??

    I agree with Retorq - if $$ is tight, buy the Jegs/Summit setup and only activate one speed of that fan. Some guys choose to activate the High speed, but under normal driving, Low is more then enough and draws less power. I personally prefer screw in temp sensors that have coolant running over...

    252 A large puddle would put you in that situation! How often does that beautiful paint come out once the salt hits the roads in the winter??

    anyone do E-fans on a obs??

    yeah, that's what i was thinking....i don't have a manual switch on mine, didn't see the need for how i set mine up. However, if i complete this "overland" conversion, I will need to. Assuming all power is off when everything gets soaked...when can I flip the switch to turn on everything...

    Thanks Atomic!! 248 Quick question....If the fan motor was completely submerged while running, would it short out?

    anyone do E-fans on a obs??

    Monstar Monstar.... Just a disclaimer - ppl have had success wiring in a Volvo 2speed setup to these fans and its MUCH cheaper then how I did it below. Spec for pipe: 1.25 OD x2 3/8 threaded ports (i.e. bungs) I believe when I ordered it, i asked for 7" in total length (not 100% sure...

    anyone do E-fans on a obs??

    that's exactly what I have and I love it.... (check my previous posts). That thing has x2 temp sensors, so have a pipe made for you that you can splice into the upper radiator hose (my previous post has a link to a company that can do it) ---------- Post added at 12:37 PM ----------...
