PE4200 & ScottyII Installed

[Cummins4Life]

PE4200

Hopefully this will rid me of any lift pump troubles. Friday I had Rip Rook install his PE pump and upgraded fuel lines to the fuel filter. Acouple hundred miles later so far so good. 22psi at idle and 17psi on kill uphill and 18. 2 mpg to boot.



ScottyII

The same day I got a ScottyII-AFE from Rip and installed it with the help of acouple fellow Northwest Bombers. It didnt lower peak EGT's on 4x5 and up but below that setting it lowered them at least 100*. However it does slow their rise and cool more quickly than anything I ran before so it works well. The only drawback is the noise, with the windows down I cant hear any difference. In a sealed cab to me it sounds quite retarded, not overly loud just kind of a cheesy sucking sound.



After these installs we went to a local dyno and I layed down 417 hosepower Aint no monster but it sure is fun! Oo.

Hey Zach!



Good to hear the Scotty is working out for you, although I am a little surprised that its not working all that well at 4x5 and up. Did you check for any 'cooler boot leaks, or a leak on the cooler itself? It may simply be that the HX35/12 just can't keep up to your mods, as an HX35 really isn't much good over 350 ponies (not sure what a Piers 35 is good to), however you may want to snoop around for some other leaks. How much boost are you pulling in 4x5 and 5x5 mode?

Was rated at 350hp and recommended wastegated at 36psi, when they were first released a while back. Not sure if its changed since I had mine.

I'm sure I need a bigger turbo or exhaust housing at least. I hit 40psi on 5x5 with no boost leaks, used to hit 50 before the adjustable boost elbow. The ScottyII gave me what I wanted, the most EGT reduction I could get without stepping up to a new turbo.

Somewhere along the lines I missed something, maybe. Are these pressures safe for the inlet side of the VP44? Seems that I read that the pump was designed for a max inlet pressure of 18psi.



Or, maybe I've been smoking too much of the funny stuff. Can someone set me straight? I don't want to start a flame war here, just gathering info as this thread applies to my situation as well in that I need to replace my lift pump.



Thanks!

Same numbers here

We put the PE on my truck on Saturday.

I have the 22 psi at idle, 20 down the highway and 17 at WOT with the TST Powermax Comp [level 9 all the time] and DD 3's with the B1 Kwikspool.

I fully expected to have 'limp mode' from the over 18 pressure... but nothing yet.

I am still concerned that this is overkill and might change out the spring to lower the pressure some and maintain volume.

I have my PE mounted up on a custom bracket on the frame right under the drivers floor area. Nice safe spot... no road rash on it there and ties into the stock line there real nice. Heck it bolts right onto that hole where the factory bracket is.

Kat, I remember eating dinner with Bill and Stefan Kondolay and Piers Harry (among others) at a get togther some of us NW BOMBers had a few years ago. Anyway, the topic came up about the PDR HX35. At the time, Stefan was racing the DTT Ram with the aforementioned turbo. Apparently he had also tried an HX40. He seemed to favor the spool-up of the HX35. He was also running it up into the high 40s (psi). I remember Bill telling Piers that he should really advertise that the HX35 is the turbo to go with to at least the 375 BHP range.



I ran 448. 2 BHP/1,018 lb. ft. Torque with my PDR HX35/modified Banks 14 cm&sup2 at Diesel Thunder II (Sept. 2002). Before I set the Banks wastegate actuator to 40 psi (ok, it will actually peak at 41 psi... ), I peaked at 49 psi (courtesy of my SPA tattle-tale peak recall).



Piers did in fact change his recommendation as to wastegate setting on the PDR HX35... it's now (and has been for quite some time now) 38-40 psi.



BOTTOM LINE: I still believe that the PDR HX35 with a 14 cm&sup2 turbine housing strikes an excellent balance between performance and great driving manors... no lag, almost no barking (manual), none at all with the auto. , and performance right where I live!



Now, if being the Dyno King is your game...

Thanks for correcting the new figures. Just was relaying what was goin around back when I had the turbo. I ran it w/445hp a while and yes it works, but its hot. It was my backup turbo when I was playin with HX40's.

Well Kat, some of you moved on up to the BBD (Bigger, Better, Deal) while there were still those of us that thought the PDR HX35 was pretty much everything we ever thought we needed.
