Engine/Transmission (1998.5 - 2002) PF-100 or PF-150??????

[KBrennan]

Here it is, I am ready to get a new Lift Pump and filter system. I have decide to go with the Air Dog mostly because of the cost but also to the great customer service I have received so far from the Pure Flow. The question is if I should go with the PF-100 or 150 . It is a 99 2500 with 137,000 miles running a Banks Stinger kit, S&B cold air intake and plan to up grade to an Aurora 3000 turbo, ATS intake manifold and a slight injector upgrade maybe 75 to 80HP. I have pushed the idea of upgrading the VP44 and intercooler but that is way out there unless one or both die. I use the truck as a daily driver and pull a 12,000 pound fiver for vacation trips. I don't plan on ever doing competition events are anything radical like that. Thanks in advance for your comments.

Welcome to TDR and AirDog!

The 100 is all you will ever need. I have over 300,000 miles on my AirDog with zero issues.

Godspeed,

I got this from piersdiesel.com - "PDR recommends it is best to not have more pump (rating of GPH) than what is needed for a given application, as the pump will live a shorter life by bypassing more than normal. For example: A stock engine to 600rwhp truck should run a 95gal per hr pump, as a 150gph pump would not benifit the engine at all. Under 600rwhp the engine just isn't capable of using that much fuel and would be bypassing it's life away. Also the 150gph systems tend to be louder units, which can be anoying for a everyday driver. 150gph or higher units are for the extreme hp aplications only. "

I see your points and it is good to know stuff. I was leaning towards the PF-100 but was not 100% sure why and there is always that nagging voice on one side that sayd biger is better. Thanks again. Next will be what new VP44 to go with. I'm likeing the Blue Chip Special X VP44 but ouch what a price tag.

the airdog 100 is an easier install and supports up to 600HP.

towing you are unlikley to use more than 6 gallons in an hour, the rest goes back to the tank.

the special X bluechip pump is designed for better atomization but will not flow as much. It is the opposite of a HRVP, it has the SMALLER HO plungers and slightly advanced timing. Good pumps, but I would not replace it if yours is not going out.

you can advance the timing with most chips.

Trust me i wont replact it until I have to but when I do I want the best all around pump i can get and i hear that the Blue Chip is the way to go. It coded on me twice during the winter when it was -10F out side and I got a dead pedle at 70MPH about 6K miles back. I know that these are warning signs of the begining of the end. lets hope I can squeze another 10K out of her.



Thanks everyone for the help. I am kind of new to the diesels as far as things like this goes but with everyones help here I am learning fast.

As far as the parts that go into a VP all rebuilders use the same stuff, only the configuration changes. Meaning the parts in a Blue Chip are no different than anyone else's. I had a Blue Chip and it lasted for 262,000 miles, not displeased at all. Bought a Scheid this time, closer and less $$.

Godspeed,

Trent, How many miles are on the Scheid? I understand not all rebuilders replace the VP44 electronics. How do you tell if the did. I know Blue Chip is high dollar but as the saying goes "You get what you pay for"

 

[blacksheepdiesel]

I just put the Scheid on my truck and it has 18,000 miles. However, I have installed 3 other Scheid pumps over the years and they are all still going. Scheid assures me they always change the brain.

I understand "get what you pay for" but if the rebuilder is reputable and less expensive why pay someone else more $?

Godspeed,
Trent
