Engine/Transmission (1998.5 - 2002) Difference in VP44's????

[Bobalos]

Im looking @ replacement VP44's for my truck & I see that II has a stock & a "hi Perf" pump. what is the difference? the only mod I have on my truck is a Bully Dog outlook. I use the truck to pull my trailer & race car to the track, thats it. I want it as reliable & low maint as I can get it. but... ... ..... that trailer is REALLY damn heavy & the truck gets a workout every time I make the tow up the hill to the track. I figured a little more power would not hurt it any, which is why I went with the outlook (& am thinking about an exhaust).



thanks a bunch guys.

the high perf pump will give you some more power beccause it flows more fuel. Im not sure that you will like it if you tow a lot. ost people that run this pump have a lopey idle. It can make it difficult in backing a trailer and towing at low speeds. I would just get a stock IP.

Blue Chip Diesel has a brand new VP44 that has upgraded electronics like the II HRVP and also has some other upgraded parts that will certainly add to the life and performance. It's a upgraded option to a stock reman.

not hijacking the thread, but do the hot rod pumps put out more total fuel then say a so or a ho pump would? Would they be more reliabe also?

After the VP I would install a set of RV 275 injectors.

You will love them, 55 more HP and better mileage.

Best Bang for the Buck out there.

what is the down side to the 275 injectors?



thanks

Hey Bob

As far as I know there is no Down Side.

If you are looking to stay fairly stock, not going to fall off the HP slope towards never enough.

Just my thoughts.

Actually I think it's more like 40 HP from everything I've read. You will definately see an improvement in uummph! Not huge, but you will see a bit more power while towing. If you add a used EZ for a couple of hundred bucks you will really notice even more uummph!

I didn't read your signature though... . If you have an auto trans only add one or the other or your trans will not like it. You would probably be able to find used 275s & a used EZ for about $400 for both in the TDR classifieds.



JMHO,

Right on guys, thanks for the info. the Bully Dog Outlook that I have, has 5 programable power stages, & seems to work pretty well. it also has a defuel feature if the EGT's get too high. I just put it in, so I dont know how well it works other than the few miles Ive put onto the truck since Ive installed it. when its on max HP, it sure makes a good difference in power.



I guess the trans went out on the previous owner & she had it rebuild @ Aamco, Im counting the days until it drops over dead. so far it runs like a champ. I have to say with the exception of this injection pump, the truck as been pretty darn good to me.



thanks guys.

The RV275's are a pretty nice upgrade and they're pretty affordable too.

Bobalos,



If you need a pump it's a good upgrade, the lumpy idle is rare but does happen. If you're not needing a new pump then add the 275RV's and a Edge or Van Aaken box and you'll be real happy and it'll cost you less too! The combo is tough to beat and lost of customers here have done it and are very impressed. Some MPG if you drive easy too as a bonus.
