Well, first off you posted in the classifieds.

the VP44 is the standard pump that comes factory the 98.5-02 autos and 5 speeds got the SO or standard output and the few 01.5-02 6speeds got the HO or high output.
The HO is built for high pressure low volume it can support upto 480 in most cases sometimes 500+ if the pump is real fresh.

The SO is made a little different with less agressive timing but larger plungers and offers high volume at low pressure so while the low end isnt as strong it can support upto 600 or sometimes 650+ if the pump is super fresh.

The HRVP is a combination of the SO and HO parts to create a high volume and high pressure pump that can be run on both trucks and with the extra pressure and timing of the HO parts and the extra volume of the SO parts it adds from 40-100 hp and is suited to those that dont want to run a comp or other fueling box but need a replacement VP anyway OR those like me that Have a HO truck and want to make more than the 480hp limit of out worn HO pump. It must be noted that these pumps compromise the already short life span of any VP44 with their high performance design.



The dragon flow is similar to the HRVP only is that much more Volume at high pressure and the increased HO timing. where the sleeves or whatevers are bored in the HO pump to accept the bigger SO pistons on a HRVP this pump gets bored out that much more to accept even larger pistons/plungers. This pump Is considered Competition only as it Has to bee run with 250hp or larger injectors and has to be run with .93 or larger crossover tubes and or lines. The reliability is completely compromised on this pump so its for only the most serious enthusiasts to run on the street or for Off road only dedicated pullers or drag trucks.

Hope this helps if not Use the Frappin search feature or Get the money to buy any of the three and call the vendors themselves that is why they make the big bucks to put up with all of our questions and to SELL(twist our arms into buying) us the products! ! !

I have put in 2 of the industrial injection hot rod pumps. Big difference between it and SO pump.

I have the HRvp44 and i love it so far. It gives your truck a little bit of a higher idle, but i love it. It's alot better then a stock vp44. It improved the bottom end and makes some smoke. I have about 2-3000 miles on it so far. I'd suggest the HotRod pump, worth the money. I also put on a stealth cover while doing the pump and i recently got a comp box and there is very little interference with the two working together. There is a little interference at slow speeds when your bearly on the throttle. It really rolls the smoke with the comp box on level 5, till my clutch slips. Thats another thing, i put my hotrod pump on and i only had an edge ez on and the clutch started slipping when you lay into it. From what i heard the hotrod pumps are a true 100hp.

As usual they are full of ----. pgdsm from this board said "15 k KM or about 8 months. On bd hp vp44 seized rotor, always ran two stroke and never below 16 psi of fuel for it's whole life."

i would never put anything but an SO pump on my truck. the difference in price is immense, and once you start lookin at 1500-2000+ dollar vp pumps whos failure is inevitable, i would just p pump it.

on the other hand, if i had deep pockets and enjoyed doin vp swaps, i would prob put one of those high horse pumps in. but my pockets are shallow and have holes in them, and i have bad dreams about vp swaps.

not sure how long the BD HP pump has been out but according to Dave @ BD they have had only 1 come back and it was chalked to contaminated fuel...

would wire tapping a hrvp44 have even more power gains?
less. The HR's are already slightly turned up so there is less to be gained before you hit the 650hp wall.
