Engine/Transmission (1998.5 - 2002) will vp44ho work a standard output

[Turboman]

I am trying to see if a vp44 ho will work on a 1999 model pickup that belongs to a friends son and has a pump out.

Turboman,



I have been running an HO pump on a "01" SO for a year now without any problem.

Ian, how much performance improvement did you notice running the HO pump?

My seat of the pants opinion is that it added 20-25 hp.

Thats funny, because I have a HO off a 2002 6 speed, and the threads in the 911 say it wont work. I have also contacted a few shops that also say the HO pump will not work on an ETC. That is the reason I have my HO for sale!!?

I have seen those threads. I posted to a couple of them.





A little over a year ago I was shopping around for a replacement SO pump. At that time they were very hard to find.



When I contacted BD and asked if they had any new pumps they told me that the had several HO pumps in stock, but did not stock SO pumps because the price was the same as the HO and that when guys in that area had to change out pumps they wanted the HO since it resulted in more power.



I bought one.



Truck runs strong and does not set codes.



I also run an Edge EZ.

Do you run a 2002 ETC or ETH?

2001 ETC

So you have a HO vp on a ETC motor??? What year was the HO originally made for? And the motor that it is on is a early, or late 2001, (2001. 5) (Disks or Drums)?????

Yes, HO in ETC. It is 2001. 5 truck,very late in 01 model year. The HO pump is a -028 version, other than that I don't know that it can be associated with any particular model year.
