So what are the options for onboard air resevoir tanks?
I know sun performance has them.
is there any other options?
I remember reading a post about a converted propane tank.. how much pressure can they hold before the relief valve blows?
-
I have a Sun Performance 2.5 gallon tank in the Gnewt.
It takes a while for the ARB compressor to fill it (maybe 5 minutes), and then the lockers runn all day, without the compressor having to come on again.
But it's nowhere NEAR enough air to air up four 31 X 10.50's from 10 psi to 23 psi.
-
I cut down a 4 gallon tank to 2.5 gallon to fit between the sami frame but you can buy tanks almost any size from industrial supply companys. Usually 6" round are the common ones.
-
im now running a dive tank think its 60litres , just about to wire up an compressor probaly take 30 mins to fill it

My onboard air tank is inside my tube bumper. ;D

i have heard of this, i have 4 tubes, front + back. is this really practical? how much air are you really holding? got any good close up pics of the end with the air fitting?
-
 Its a little more redneck than your bumpers!  Just one 4" tube across the back.  End caps are a couple inches inside the tube with fittings and gauge there but we're going to have to move them cause they still stick out too far. Not sure how much it holds.  This is only pic I have right now.  (http://www.eye-irritant.com/august2004/bumper%20-%2011.13.04.jpg) ÂÂ

oops hit enter to quick on the last one
Lilred can we see some close ups of the those rocker knocker bars. How did you mount them? We have seen alot of steel box type rocker protection but your are the first tube ones I have seen that appear to by up on the body and not under it..
-
  Sorry but I don't have a closer pic of the rocker bars.  :( They too are pretty simple though.  Its a 3x3 (I think) piece of angle iron on the corner of the rocker.  Tubes are welded to the side facing out.  The other side protects the rocker from underneath but doesn't reduce the ground clearance much.  They're welded to the body support members underneath.

question, having compressed air in the rear bumper is that not a little dangrous if someone hits you hard in the rear ???
just a thought

Exactly what I wonder. And also the reason I will never have a pressurized bumper! Just because a lot of people have done it, doesn't make it the most intelligent move on the planet!
-
 I'm not scared!  Try to keep it in perspective. How many people with these bumpers have you known to be injured? I'm more likely to get injured in my "safe" daily driver going to work but I don't stay home because of that. Now of course, I've jinxed myself!!
-
Isn't it more about volume than pressure? I mean,,,160psi isn't going to explode if it cracks.

I wouldn't be worried either ... if the bumper is hit, the air will leak, not explode. Sorta depends on the material used for the pipe bumper (and the pressure it's holding, but an impact that splits a pipe bumper would probably have enough force to cause other worries.
-
I wouldn't be worried about the bumper full of air. I don't think it's enough pressure to really do any damage.
Somebody at my work suggested PVC pipe as an air resevoir. I was a little sketch about it but I looked up the specs on PVC pipe and a piece of 6" Schedule 80 PVC pipe has a pressure rating of 280 psi that's almost double what most of us would be using at say 100 to 140 psi.. So there has to be a reason nobody is using PVC pipe.. Is it the fittings that are a concern? I would think PVC would be really easy to work with. Think of all those spud guns we built as kids. Creating an explosion in a piece of 4" PVC enough to shoot a potato for 300 yards has got to be serious pressure...
Just some food for thought here's a link to the PVC chart.

Did some more searching and found this site where a guy found a place that sells used air tanks.
Specialty Truck Parts in San Jose.. Here is the link to his article.

Be careful with PVC under pressure ... it will shatter (like glass) when it let's go (i.e. boom)
-
PVC also breaks easy when it's cold. but the schedule 80 IS a lot better then sched 40. ÂÂ
A tip for anyone looking for onboard air storage. Hit a welding shop!!!! Buy or lease a small co2 or nitrogen tank and spend the $80-100 for a decent regulator. That gives you from 2600-4500 psi to start with, you can regulate it down as far as you need for an air locker, plus co2 expands as it's released. IIRC a 2' tall tank hold something like 400 cubic feet of co2 |removethispart|@ 2600 psi. (not sure of the exact #, but it's a LOT more then most people think!!) Also runs air tools all day too!
An added benefit if you get a real good regulator, (few hundred $$) is if there is a fire, you can run the tank wide open. Co2 is GREAT on class b-c fires!! )liquids, gases and electric)
Plus it can cool your "after run beverages" too! ;D
Anyone know any drawback to using nitrogen for this?

I'm starting to agree on the PVC thing. I have seen some threads on other sites with the BOOM warning..
Even though it's rated at high PSI it's still not recommended by the manufacturers to pressurize it.

Call Sun Performance and talk to them. That's where I got my tank, and pump. It's nice stuff, remember? :)

i found CO2 used to ruin seal as its so cold and makes them brittle
