It depends, I don't know to much about the Van Aaken box or if they offer different models. Anyways, you don't want to stack more than 1 box that advances timing. The edge will advance timing for sure and I don't think the Van Aaken does, in which case it is fine to stack them. But look into it and make sure first. With that said, I would look into injectors over and above stacking boxes. As is your stock injectors are too small to flow the full amount of fuel the edge will provide so you won't get a huge gain from stacking boxes on stock injectors. Also with stock injectors trying to squeeze that much out of your pump is really taxing it pretty hard. That just my .02 though. I would hang on to that Van Aaken though and stack it down the road if I were you.
my buddy ran the stage 3 jammers with an edge comp and was starving for fuel. We ended up putting a FASS on his truck, but if you aren't looking to spend that kind of money I would suggest looking into a stand alone pump and a big fuel line kit. http://www.glacierdieselpower.com/product.asp?pf_id=9852MAX
That is the fuel line kit
Starving your VP is something that you don't want to do. If you have the money I would suggest going with a full on FASS system or an Aeromotive or Glacier system because they have better filtration, but if you're on a budget, the stand alone works fine.
The VA box advances timing. It is real similar to the Edge EZ. I would not stack it with a juice. You will have alot of timing stacked. Probably too much. Definatly go with injectors instead. An aftermarket lp will give you reassurance that you aren't starving the pump.
Thanks, I didn't know if the V.A. box did timing or not, good to know. Since it does timing I would say don't run it. You'll risk popping your head gasket with too much timing, and you would almost definitely over spray the bowls on your pistons.
Yeah you can use your stock injector bodies for those and shouldn't have any problems, its an easy switch. If you know someone with a set of stock cores just lying around I'd put the nozzles in those and then give them your stock ones when you're done. It just makes it easier that way you aren't sitting with your injectors out for a while, and if anything happens during the swap, you aren't screwed cause you still have your stock injectors.
Go ahead and replace the o-rings and copper sealing rings while you are at it. They are cheap and give you a little insurance against leaks. You can get them at any shop that sells or services Cummins engines. Just give them the engine serial number and they can pull up the part numbers. Don't go to the dealer though. They quoted me $3.75 per o-ring (I don't remember which one now) and I got them from Triple-T for 60 cents each.
Here is a pic of the injector.
If you save it to your computer you will see the copper ring and one o-ring. The other o-ring goes on the crossover tube.
Also be easy with the injectors and nozzels when doing the swap. Don't let the nozzels fall to the floor or take any damage. I've had two injector tips break on me, the second one taking out #5 piston on it's way. Like said above though the new copper washers and orings are a great idea. I keep a spare set in my toolbox at home since I've gotten so good at changing injectors out.
Have fun with the added fuel and start saving for the tranny upgrades. :Thumbup:
