To all whom own a Bull Moose

[OldIron82]

Just curious as to what equipment you need to support it. Turbo size, bottom end upgrades, timing, piston coating, etc. In a nut shell, is this pump streetable without rolling coal to horribly?

I'm running one on my rig. 6.9 idi. No major upgrades, head studs, 0.015" decked and ceramic coated pistons. HX35 turbo w/ intercooler, max ~19 psi boost. Seems to be a good combination. It will definitely smoke if you get into it too fast, but once the boost comes up it seems well matched. I'd say 15 psi boost minimum to use it effectively, 20 being better. I would hesitate to run that boost or that level of fueling without dropping the cr a bit and ceramic coating on the pistons.

a GOOD 093 or larger turbo and innercooler ARE A MUST!!!
i would also get the mark II injectors.

i ran a bull moose with the misters and a worn out turbo, EGT's spiked to 1250-1300 which cracked my head.
and stress cracked my pistons.
i will be running this pump again after i get my engine back together.
with a rebuilt 093 with a wicked wheel.
with a buncha performance parts i decided to get.


i did opt to ceramic coat the pistons.
the less heat to the compression rings the better.
keeps the aluminum alive!

i did not have studs on the last engine, and the headgaskets did just fine,
however i will be running them on the new engine.
im also thinking about getting a stud girdle.

now while normal driving with the set up mentioned above
i could keep up with a stock powerstroke in my crew,crew cab, short bed (stock CC LB frame) with 3.55's and a ZF5

if i drove conservatively, i would get a small puff of blackness out of my pipe when under a load (lower rpm's after shifting)
not bad at all, and nothing johnny law could complain about (less than the required 10 seconds)
BUT....
if i had the hammer down, running it hard, plumes of fuel can be seen behind me until i decided to let up.

so the answer is yes, it is a streetable pump, if youre running the required equipment.
but, you will be driving by pyro....
again, my pyro would only exceed recommended temps when i was well above the posted speedlimit which noone obeys.

stay below 1100*
or you will have a nice paperweight.
timed at 9.5*

FYI, make sure you tell them you're an OB member! you get a slight discount!

but dont tell anyone else

Everything Idioit said. With my 093 I can still blow smoke up to the redline. Need more air but $$$. Intercooler absolute must. I went without the first few months. Bad idea. If I hadn't bought my bull slightly used at a discount from this forum I would've gone with a moose junior since I'm not in an all out hp race in my truck. But I have the fuel now

Call Conestoga Diesel Injection. They have a great web site and offer from simple mild to wild pumps. They are great to work with too. Nothing needs to be done to the bottom end like studding the mains or a stud girdle. Its plenty strong in the stock form.

if you don't have an intercooler get one first.with my 2nd gen banks and cxr intercooler it's a match made in heaven.
most likely not many people would bother with a smoke puff limiter with my setup,because i could only roll coal under one condition; under load in OD before a downshift.
once i added the smoke puff limiter (which with the e4od trans,i probably could of simply cheated using a lower tps wot voltage setting,to get a sooner downshift,i didn't want to do that because i love how hard it pulls in od! lol) i have to work pretty hard to make smoke.i can't and couldn't before the smoke puff limiter,roll coal off idle.the banks simply spools too quickly.
i keep my EGT's @ 900 - 1000
(banks states 1050 is a safe max w/probe located @ turbo pedestal)

the bull moose isn't just steetable,it's very heavy duty work ready.if it wasn't it wouldn't be of any use to me.i was pretty happy with the trucks performance before the bull moose.now it's just a super hard pulling fun mother to drive.

i went from like;
oh man i have to use the dump trailer today.i sure wish i had 4.10's when i need to load truck and trailer on days like these.
to;
oh hell yeah! i get to use the dump trailer today!

Great feedback guys! Thank you. We don't hear enough about what other tweaks our customers do to get the most out of their Moose products, so this is very informative.

Mel, what does the fueling curve look like with the omega pump? I see 130 cc max, at what rpm? Do you have a graph you could share? Also still 3600 rpm limit?

 

[Agnem]

All of our fuel ratings are guaranteed spot on at 1400 RPM. As the RPM's climb, the fuel curve does start to drop off after 3000 RPM. Most pumps will make within 5cc of the advertised spec at 3000. Once you get to 3300, it starts to drop off sharply by design. This is to keep the engine from blowing up if you ever got into a full throttle no load situation. By 3600 RPM most of the fuel is gone.

 

[Greg5OH]

cool, so basicaly up to 3300 the omega would see approx 125cc, then a sharp drop 3300-3600?

 

[IDIoit]

also, is there a way to to increase the RPM's?
mine seems to die out @ 3100-3200. maybe less timing?

 

[icanfixall]

Brian we can and have seen some members install a chevy pump advance spring. I recall a member rotinely saying he saw 4400 rpm daily..... Till it blew up. Just because we MIGHT be able to rev to God knows what does not mean we should do it all the time. Some like it hot and some not...a

 

[79jasper]

Maybe if you had everything balanced and such.

I had my original 6.9 spinning 4k when it spun the bearings. Hit a hill grossing about 10k so I wound it out in second (c6) knowing id need it. Started running out of power so I dropped to 1st. Held that for a little and still ran out of power. I pulled over to pull it in low range and about the time I got it in it stalled. Lol after It cooled off it started back up and made it another mile before it was totally locked. 230k on original engine and never dropped below 35psi of oil WITH 2 spun mains!!! Poor old thing was worn out.

The 7.3 turbo in it now will spin about 3900. Not always necessary but sometimes it makes things easier.
