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! ! !
