Pretty dang interesting watching a diesel tractor motor running on a dyno for work, compared to a race motor for speed. I understand you want torque for both motors, but one relies on torque more than the other. Great video.
I've pulled Donner Summit with 600 horse loaded and had a cattle truck that i know was loaded to just suck me up and leave me trying to act like i missed a shift when we all know he had some Pittsburg goodies that i didn't
well done ,, i love seeing big Cats on the dyno ,,personally i don't have any CAT power ,,my pulling truck is a very old Pete 359 powered by a very unusual 12V92 TA ( unusual for a truck ) ,not the most fuel efficient vehicle there is ,, but when i start climbing a long steep grade and i start passing people it's a sight to see ,cause i don't slow down on hills ,,my horsepower and torque figures are really close to this 6NZ CAT ,,it's also turned up just a bit , i'm at 820 wheel HP and 2580 torque ,, at 1300 rpm i've got a huge weight penalty too because that huge 18 liter engine weighs 4200 pounds without intercoolers
yes 18 is big ,, it's also not very common the 12V92 was not commonly used in highway trucks other than heavy haulage trucks meant to pull huge loads and my truck was speced exactly that way 34K rears 20K front with a really odd transmission setup ,,I have a 4x6 twin stick 24 speed with a 3 speed final drive

My friend’s 2 peterbilts are broken down constantly. Today, the 6nz needs a new head and turbo and radiator. 11k. Less than 100k on rebuild. Never ran hot. No racing or hard driving. Pittsburgh box on level 1. PDI exhaust and turbo. Turbo cracked. Head cracked. Machine shop said too much fuel. The other truck, a c15 accert, constant issues. PDI cam, platinum cat rebuild, pDI computer and Pittsburgh computer. Blew head gasket or worse. Just now realized factory 18.1 piston may be issue. Needs 16.1. Gonna go back to all stock on all trucks. Gonna rerate both to cat 625hp tune. Possibly switchblade turbos. Mega money game. Yikes

DO NOT underestimate the ISX with common rail injection. There is over 800 wheel hp available with just tuning and turbo swap. With the after treatment "fixed",that engine is a beast
@@dougkratz5269 ....absolutly correct. Pittsburgh Power has the know how to make them produce. Took a lackluster 600 DEF ISX Cummins to them...now pulls 126,000# gross like its running empty. Very happy customer.
What do y'all charge to put on a dyno and see why my truck acts like it's starving for fuel at 1700 rpms? Fuel pressure stats around 95 on my gauge but the boost gauge starts to fall.
Those engines are really amazing, & I build race engines! You could make a BBC make 3000ftlb, & 3600hp with out much problem! Except you will never actually pull the extreme weights those trucks do! Never mind you could never keep all that torque for so long! It’s really crazy people try to pull 20 ton with a pickup 🛻 today 🙄🙄🙄🙄! Most have no idea how big the cranks, rods, pistons, transmission & gears ⚙️ & cooling systems are on those trucks! Never mind the chassis & brakes! They are made to pull mountains ⛰ @ WOT for long periods of time! A pickup might have similar horsepower compared to low power tractors, but they don’t have the huge torque & parts! Also I love that you could make that big power, without blacking out the sky 🙄🙄🙄🙄!
David Drescher it’s a refrigeration part to fill up units with refrigerant. You can pick one up at any refrigeration store and add the adapter at the ends to suit you’re purpose. You can only put it before the high pressure pump. They don’t make any to withstand 3k-50k pounds. I think they only go up to 400psi.
@@jorgenunez1825 There's no place to in these cat fuel systems that's over 100 psi besides INSIDE the unit injector, the injectors is the "high pressure pump". The pump on the front of the engine is just to suck fuel out of the tanks and pressurized it to 80-100 psi in the fuel rail to the head.
That's funny I talked to you guys about my 6nz running hot when pulling I was told its because I have a marine cam and injectors in it theres nothing I could do to stop it but this truck is set up pretty much the same parts as mine it didn't seem to run hot
I’d like to see what kind of fuel economy he is getting pulling 80,000 on the Interstate. I expect he is seeing some good numbers if he drives it in the sweet spot.
My 700hp 6nz made 9 empty and 5.5 at 120k heavy hauling. Our stock trucks couldn't come close to that. It's all in how fast can you get it up to speed and easily maintain it. The amount of time I spent at wot was always way less just simply because I had the hp.
@Donald Clark Cruising down the interstate at a set speed, you're not using full output at either the 550 HP this engine came with or the 1000 it's making now. The better flowing components that allow you to make 1000 HP increase the efficiency at partial loads too
Donald Clark wrong mate! Efficiency is how you get better fuel mileage.... average throttle percent is king for mpg. Now you put your foot in it and yes a 800hp anything will eat the fuel fast💦
I was talking my cousin in Europe. He says the Volvo D16 has 750HP with 2560 torque and with that horsepower/torque engine not available with manual transmission because it will destroy the clutch. What is the torque on that 1000 HP engine?
I would think any air in the fuel line would be unacceptable. Maybe a little on low fuel because of that sudsy diesel fuel otherwise a fitting or gasket isn't sealing allowing air to be drawn in. Possibly pickup screen blocked with debris in tank causing higher vacuum which would cause normally sealed fittings and seals to allow air in. That's why I prefer AN fittings over pipe fittings, although pipe fittings are somewhat self locking if tighten well.
Anyone think to change the bypass valve in the filter head to correct the pressure loss, maybe the marine engine has a higher bypass pressure and the standard 6nz wouldnt hold up
Good gosh almighty , that torque makes my sticker peck up ! She hung in that range for a good while too ! Bruce you still are tops in my book ! Not trying to nit pick but you never addressed the issue of the source of the air , just a band-aid on a scab is not my style ! Boo lol .
swampratt36 the issue with air in the fuel ended up being the primary air filter housing was cracked and the customer opted to take the truck as is and was going to address the air in fuel system himself, as far as getting more fuel pressure and/or volume he had his own plans to improve it, it had stock fuel lines and fuel pump and it seemed those marine injectors demand more fuel volume/pressure than what a stock 6nz comes with
I have been driving a 2006 Peterbilt with a C 15 it has twin turbos. Me and the boss ain't seeing eye to eye I think we can get more horsepower out of single turbo but he doesn't think so. What do you think?

Also, I am befuddled at the fact a semi on average only has 15% drivetrain loss when most C5/C6/C7 Corvettes have around the same? SOMEONE PLEASE EXPLAIN THANKS IN ADVANCED AUTOPARTS
I'm just curious for knowledge purposes.... Is there anything that can be done for more power north of 550 hp on an ACERT C-15 from 2004-2005 without tearing the entire motor down to the block?
You can make 750hp easily from a bxs acert, its basically a 6nz once u remove the IVA (intake valve actuator) system which is bolted on to the rockers, delete the IVA’s, low compression 16:1 pistons, stage 1 head (you can get them ported and fire ringed) cat c15 arp head studs, anti friction coated rod and main bearings, also get your piston heads coated while youre at it, big single turbo or keep your compounds, fass or air dog lift pump (i dont remember the size of GPH needed but just contact air dog or fass and they should guide you to the right direction, and finally 800hp marine cam and the biggest injectors possible i don’t remember their full part number or size but the cat guys call them “89” injectors lol hopefully with some asking around they can give u the part number for those, but with all that you can safely and reliably push 750-900whp If you want 1000-1500hp than dual lift pumps, stage 3+ custom head, upgraded cat fuel pump, custom injectors, dual bigger upgraded turbos, arp studs on everything possible main caps rod caps head studs, steedspeed one piece manifold and upgraded valve springs, retainers and all that not so fun stuff, most guys run c18 liners pistons and rods to push that power but idk if its necessary (it probably is)
Check out Riehl truck repair in landisville PA. Dennis is a mastermind with me mechanical cat pumps. There much more to it than turning the screws IF you want the engine to last and be reliable. Also will want nozzles and a better turbo. Call Dennis, he'll shoot you straight and make it run(and fun!)
@@thinairdiesel3158 that's exactly right. I like the fass system and everything it does, but a lot of times people want to put a band aid on a still bleeding wound.
And they didn't entirely solve the fuel pressure drop either, aside from the air in the line from the gauge they were using, pressure going into the head was low at high rpm and the way the fuel pressure regulator is set up, technically you should see less tha n 5 psi drop going into and returning from the head. Should have gotten new orings on the injectors and a new valve in the regulator with the updated spring.

Yes it called 625 king of the hill kit
You can make 750hp easily from a bxs acert, its basically a 6nz once u remove the IVA (intake valve actuator) system which is bolted on to the rockers, delete the IVA’s, low compression 16:1 pistons, stage 1 head (you can get them ported and fire ringed) cat c15 arp head studs, anti friction coated rod and main bearings, also get your piston heads coated while youre at it, big single turbo or keep your compounds, fass or air dog lift pump (i dont remember the size of GPH needed but just contact air dog or fass and they should guide you to the right direction, and finally 800hp marine cam and the biggest injectors possible i don’t remember their full part number or size but the cat guys call them “89” injectors lol hopefully with some asking around they can give u the part number for those, but with all that you can safely and reliably push 750-900whp
If you want 1000-1500hp than dual lift pumps, stage 3+ custom head, upgraded cat fuel pump, custom injectors, dual bigger upgraded turbos, arp studs on everything possible main caps rod caps head studs, steedspeed one piece manifold and upgraded valve springs, retainers and all that not so fun stuff, most guys run c18 liners pistons and rods to push that power but idk if its necessary (it probably is)
0955 injectors are the onces i meant not “89” and actually you can use stock 57 or 58 injectors to push 750hp
I bet that's one hill Pullin Pete
I would be happy with 650hp
What injectors number are they running?
Every diesel especially a built diesel needs a fass or a air dog system.
They're great til they go out and you're left stranded. Best to have one on standby
If you listen to the video , they only gained 15 hp after adding the fass system not much bang for you buck$$$%?????.
Given the HP on that truck; what kind of fuel economy does it get pulling loads. There has to be a trade of at that HP.
Id bet almost the same or better when cruising, not accelerating or pulling a hill
Fuel primer on the filter head is suckin air. Block it off and get rid of the primer
I got rid of the cat fuel filter base for that same reason and better flow.
anyone got any tips on making a 3406C get some more power besides turning the pump screws all the way out
Check out Riehl truck repair in landisville PA. Dennis is a mastermind with me mechanical cat pumps. There much more to it than turning the screws IF you want the engine to last and be reliable. Also will want nozzles and a better turbo. Call Dennis, he'll shoot you straight and make it run(and fun!)

@@scottsmith6960 thanks!
This makes a volvo look like a LOL!

2500ft/lbs at 2k rpm mmmmm mmmm that's real power
You mean 1k rpm!
Air in fuel = less hp and torn up injectors
What cured or lessened the air in the fuel?
He said they
added a Fass fuel system the fass system takes the air out of the fuel so I guess that's the problem .
FASS takes the air out but the real issue to solve would be a leaking fitting, cracked draw straw in the tank, or a leaking braded fuel line.
@@thinairdiesel3158 that's exactly right. I like the fass system and everything it does, but a lot of times people want to put a band aid on a still bleeding wound.
And they didn't entirely solve the fuel pressure drop either, aside from the air in the line from the gauge they were using, pressure going into the head was low at high rpm and the way the fuel pressure regulator is set up, technically you should see less tha n 5 psi drop going into and returning from the head. Should have gotten new orings on the injectors and a new valve in the regulator with the updated spring.
The issue with air in the fuel ended up being the primary air filter housing was cracked and the customer opted to take the truck as is and was going to address the air in fuel system himself, as far as getting more fuel pressure and/or volume he had his own plans to improve it, it had stock fuel lines and fuel pump and it seemed those marine injectors demand more fuel volume/pressure than what a stock 6nz comes with
I usually don't sip Yellow Kool-Aid, I prefer the Red one . . . HOWEVER . . . this thing is a beast. 😲👌🤘
Too bad they threw the towel and got out of the on-road game.😞
JIGA BACHI they saw the future and didnt want to play with the EPA no more
