Engine/Transmission (1998.5 - 2002) VP pump + cut delivery valves = ?

[HoleshotHolset]

Anyone ever play with the delivery valves inside their VP pump?



It makes a sweet jump in power on the P-Pumps... ... and I figured the same would be true on the VP pump.



(I posted a nearly identical thread in the 1st Gen forum..... so all you rotary pump guys, including myself, can get in on the action!)

Matt,

Did you buy another truck?

 

[HoleshotHolset]

New truck for me?

Nope, but this information would apply to my car.



Working on the pic... hang on.

Here's a pic of the VP37's 'head':

Here's a closeup of the DV - notice how it looks VERY similar to what the P-7100 has in it:

MAtt,I have been thinking the same thing for a while now. No one seems to mess with them.

 

[HoleshotHolset]

I know someone has messed with them - they're just keeping quiet about it.

Thanks MAtt. Wow, that does look a lot like a DV in a P7100. Even though this does not apply to me at all I am interested to hear what has to be said. It sure seems like someone would have played around with this.

Aren't there "hot rod 44's" on the market?



Pump bidness--very close to black magic and totally shrouded in mystery.

tell ya what... if anyone has a thrashed VP out there, that you'd be willing to sacrifice for the sake of power, maybe we could modify the head / valves / poppets and transplant them onto a working VP, that way you keep the working parts working (in case the modifications don't go as planned).



Maybe I could raid the local salvage yards. Give me a few days to see what I can come up with.



Dern it Matt, now you got me started again! :-laf

 

[Brandon]

you are right they are staying quiet

 

[HoleshotHolset]

I'd be willing to buy a junked VP-44 to experiment with... . anyone have one?



Brandon: thanks for confirming my suspicions...
