Ok I spoke with the guy from pureflow and he said to use the ve pump airdog now and all I would need to change for a p-pump was a spring and a small fitting that could be had for less than $10 bucks. Now another ?, looks like we will be running the silver66 as a single for now with a set of 6x16's and an NV4500. How well do u think this combo is going to spool? Would I be better off planning on the he351/silver66 combo as time permits for early spool up? Or just run it and report back!

 

you just out right mudding it or actually doing mud drags or pit competitions? i believe rswords is running the silver62 and hes sittin abit laggier than stock from what he's told me so the 66 will be laggy (assuming) it'll suit your needs for higher rpm's but down low it may be a dog. just an educated guess as my turbo knowledge is so so

 

Just out right mudding and beer drinking, but I am trying to put a serious effort in tuning this setup because I want to get everything I can out of what we use. My only real diesel experience is with my '06 commonrail so this is my first tuning on a mechanical 12v. We going to be running 56" tractor tires but the rockwells have a 6.72 ratio so I think the NV4500 will help out alot with the lag. I plan on swaping a 12v in an '85 chevy that I have after I learn a few thing with this one.

 

hmmm putting the NV behind may do the trick with the 66; upgrade the clutch and you can always do boosted launches... even them putting it in 1st the engine should be able to crank up no problem... you'll have to row gears like a mother but man will it look and sound sweet. i went back and read your original post; go ahead and try the 66 set -up if you want to obliterate the lag then you can go to a twin set-up but the 66 will give you a good idea of where your at

 

why

 

studs are obvious; more clamping power. as for the gasket they're designed to hold more heat with out failing. different compound and better crush rings i suppose... overall just more reliable than our 20+ year old head gasket technology.

 

yeah, what he said

The only thing about the twin setup is trying to use the 66 with an S400, I don't know if the VE will be able to support a big setup like that. Maybe it will be doable until he reaches the power craving of the P-pump then maybe a big twin setup. Now that I am working regular again, I just have to find the time to actually work on it.

 

i've been contemplating the p pump conversion when i do my big build on the truck or to see wher ei can get with the VE... the cieling is kinda in the 500 range just b/c the VE cant flow anymore fuel w/o the 14mm head... but i love the action of the P pump... i get in the parents truck and its night and day to the VE but i also love the adjustability of the ve... no special ways to time it... crank it to the head

 

I'm assuming you're using an NP205 for your t-case. If so, you guys have the option of mating a wrecking yard 203 up to it and have a doubled set up, giving you way more gear ratios to pick and choose from, and saving your clutch and and tranny from severe floggings. Just a thought and mabey something to look into. It sounds like one bad *** machine. Hope to see some pics.

 

a wrecking yard 203? care to explain ? the 205 is pretty freakin beefy to start with; cast iron case and gear driven... i dont think youc could blow it apart anytime soon... but i think what i'm grasping is that it has more than just a 4 high, 4 lo range... more like 4 hi, 4 lo, and 4 locked? quick question; if i were to throw a 47rh behind the 89 will the 205 bolt up or do i have to go to the aluminum gear over chain drive?
