I just got my S&B intake and my 5" exhaust is on its way, next i wanted to get a good chip for my rig, I was just wondering what everyone is running and how you like it, perfromance, economy, any problems?
sorry its an 01 24v. cummins i mostly tow my rock crawler to the sierra's and want some more juice going up the grades. but wouldnt mind having a hot rod so i guess both?
Personally I like the Edge Comp box if you have gauges, The Edge Juice with Attitude if you do not have gauges. Fuel pressure is a concern on your rig too, especially if you are adding a chip. Do you research on fuel pressure, spend a few bucks there to insure you injection pump does not get taken out from too low of fuel pressure. Talk to Diesel Nut who posted above me on this thread, he is a wizard when it comes to this stuff and has great pricing! Hope this helps waytogo
I did a little research, and found alot of great stuff about the FASS fuel system, herd some others taking about a few other kits that were much cheaper, Has anyone had good or bad experiences with other systems? oh and i have gauges so ill be looking at the edge comp box.
Looked at the BD, lift pump and the aux. pump Prices look little more appealing than the Fass. Anyone running these?
That is one of the few items produced by BD that I don't like. First, its a similar pump to the stock unit, and requires use of a proper functioning stock unit. Also, the BD kit seems to run what I feel is an excessive amount of pressure for the VP44. Personally, even though they are more money, I am totally sold on the FASS units. They are very reliable, and with the addition of the extra filtration it is a much easier set up to maintain as well. Regulated at about 16 psi. AS for the chip, the Comp is a great unit, as is the Juice Attitude combo. Now the J/A combo can monitor your fuel pressure. Since you have gauges, looks like the comp is the one for ya. The SMarty is a great way to bring in the power on the bottom end. Only a 65hp increase total. PM on the way for pricing!
I disagree... I think this is the first thing we have ever disagreed on DN LOL The VP44 can not be damaged by too much pressure, especially 20-26 PSI like our Auxiliary lift pump kit is rated for, what does the FASS put out for pressure? Too much pressure can cause a hard start issue, that is why the BD Auxiliary lift pump kit works off of an oil pressure switch, it is designed to come on after the truck is started and oil pressure builds up. This will eliminate the hard start issues. If you are concerned about too much pressure, run the BD Bypass kit but I assure there is no concern about too much pressure, not under 30PSI anyway. Not too take anything away from the FASS kit, it is a great kit but in my opinion it is too expensive and over kill. I definitly agree with the Smarty though.
I added a Holley BLUE with pressure regulator, and upgraded to high flo banjo bolts. The Holley runs off a relay that only runs when the stock pump runs. Have been running this almost 3 years now. My stock lift pump went out last year and the Holley has been primary since. I have been running around 25psi on fuel pressure at idle. Just below 20psi running down the road. I have read in the bosch 'bible' for the vp44, that bosch doesn't recommend over 20 psi for the pump. Several I have talked to run over 20 psi and have not had a problem. I run the edge comp, but didn't pierce the pump wire. I added bosch 275 RV injectors and its a really nice combo. My injectors made stop and go driving much more enjoyable and the egts are very reasonable. The injectors pushed me over the top on my stock trans converter and started slipping, upgraded to a Goerend bros VB/TC and love it. This is just MY experience and 2 cents, good luck!
thats sounds like the direction im going with my truck, next up is exhaust, then the Fass, or alternative fuel system, chip and injectors... if my tranny holds up that long
Here is another thing to think about that will save some $$$... The non-common rail 24v Cummins motors do not need the extremely fine filtration that the FASS offers; whereas the common-rail trucks demand much cleaner fuel to keep functioning properly. The stock fuel filter provides more-than adequate filtration for the relatively low-pressure fuel injection systems on the pre-common-rail trucks. I am planning on getting the replacement lift pump made by the same company that doesn't include the filtration system. It is significantly cheaper then the full FASS system and will still provide good pressure to the VP-44.
By the way... Here is the link to the website that talks about the FASS vs. the pump without the filters. http://www.pdrdiesel.com/oldsite/FASS.htm
what is the price difference? Does the BD system hold the fuel pressure constant or does it fluxuate under a load?
so what is a good fuel pressure for a stock pump, and is it ok if it fluxuates somewhat...I.E. is there a pressure which we don't want to drop below? And is this fuel pressure in any way predicated on the mods or hp we are running? Lastly, does the vp-44 require a higher pressure?
For the factory lift pump: Should be putting out about 15 lbs at idle and maybe 8-9 at WOT from what I understand. The threshold for the VP-44 is 5 psi; if fuel pressure coming out of the lift pump drops below 5 psi, under any condition, you will begin to damage the injection pump. That is why BD offers a warning light which illuminates when fuel pressure drops below 5 psi.
I looked at the FASS and the Airdog about a month ago. Ended up going with the FASS system. The Airdog was $165.00 cheaper, but I wanted the higher filtration and a system that has a proven record. Just my $.02 Your investigations may find a different system. waytogo
i have the edge juice set up on my truck with the fass fuel system and when i replaced the stock i lost the hook up for my fuel pressure gauge. is there a fitting from some where i can get or order so i can hook it back up.
