Hey guys im new to the site as ive been doing some research on a turbo setup.
Little about my truck...

its a 2005 Ford F-350, after a few sets of head gaskets and finally warping a block on the stock powerstroke I decided to do a cummins conversion as I love the truck but not the motor....

Ive not got a 2004.5 cummins 24v in place with the 5speed ford tranny and 4:10 gears.
Im running 37" Toyo MTs on 22" Rig wheels.

for help in clearance ive got a factory 2002 manifold and currently a stock holset 1 hx35 (smaller impeller) and im maxing out at about 26-27lbs of boost but my EGTs are getting quite high, and to be honest I dont feel comfortable throwing the boat or a trailer on the back...

Ive got a 5" Bullydog exhaust and a K+N Style cold air. Im also running a juice with attitude..

now where im at is trying to decide to go to a twin setup to really drop EGTs and run some decent numbers or just a single bit bigger maybe even a holset 3 hx35 or something a bit bigger.

I would love to hear your suggestions... ideally I want to keep My egts down below 1100 while towing. Id love to have the power but really the towing is what im using the rig for... I realize I could go to some smaller tires but I love the look...

The twins im contemplating buying are a Super B Turbo and an r700..

Id appreciate any help or suggestions you guys have.

I also have a Fass...

injectors are stock, but I do have a set of 80hp BD tips I could throw on... if I did that id want to put some ARP headstuds on just to be safe...

 

he351 over a ht3b is a good set of towing twins, if you can do all the piping and lines yourself you could get away with twins for less than what you could get a big single for.
talk to Brice at BBD im sure he could get the 3b for a pretty reasonable price

btw welcome to db

 

thx for the welcome!
With those twins and the 37s what kind of boost & EGT #s would I see in your opinion?
I realize theres a bunch of variables but we're pretty much at sea level in Vancouver and its generally colder.. but realistically im lookin to keep EGTs as LOW as possible

 

well im running 35" nitto mud grapplers, and pulling a 14' enclosed trailer with a kitchens worth of cabinets in it, the highest i see is probably 900* i believe

 

those are some LOUD tires
and those are some LOW egts very nice
what about boost #s ? 35-40?

 

yeah they are!! but they have real good tread life for a mud tire imo. as for boost numbers, it really depends on how heavy your foot is, ive seen well into the 70's but under "normal" driving and towing you shouldnt see over 45-50 max

 

ahh sorry didnt realize you had a cp3 and 150s, makes a lot more sense that way
you think I could run those twins with stock fuel setup other than the fass? would I be running max pressure on the rails or underfueling the turbos?

 

actually i was running this setup before pump and sticks, so i think you would be fine cause all that was done to mine was the smarty at the time of install. the He351 is the stocker on mine so its got a pretty quick spool to begin with.

im not much of a turbo guru so maybe someone else will chime in here and give you some more informed answers cause turbos make my head go

 

haha thats what Ive been doing all weekend

just trying to find out info on stock turbos has been a PIA
so in 06 the stock turbo was the HE351 and in 05 it was an hx35?

thx for all the info & help

 

that i dont know, i thought the hx35 was a 2nd gen turbo and the he341 was before the 351, but for all i know its the same turbo .

you could also run the hx35 with the 3b as for dropping egts i have no info on that.. you could also run an s400 under either one, which will make piping alot easier since its a clockwise turbo rather than counter like the 3b.
