- Wondering how to add more horsepower to a Cat C15, C7, C13, or 3406 engine easily, this video describes the best and easiest way to do it. A simple rerate can added 15, 25, 50, or even 100 horsepower to your Cat C15, C7, or any electronic Cat Diesel Truck engine without changing injectors, turbochargers, pistons, or other expensive hard parts. Interested, then watch the video to learn more. A Rerate can be performed at any Cat Truck Dealership. Comments and questions can be left in the comment section. Did this video help you save time or money? @AdeptApe on Venmo or AdeptApe@yahoo.com on PayPal for donations, thank you so much for supporting the channel!
I think Its Great what you do AdeptApe! Thank you from Proud C15 Acert owner!
That was a really good way of telling the pros and cons of both sides of the story, at least for someone that has worked on them. Thank You.
That answered ALL of my questions. Thank you.
Awesome.. I like your channel got 2 c-15s and you been very helpful.
my company uses cat and cummins isx. the intermodal uses 579s and volvos with 600 hp isx and the flatbed and heavy haul uses cat c15s and c18s. we have a c500 with a quad turbo 3412 (1300+ hp) for 150 ton heavy hauls. the cummins dont break down much and get 8+ mpg and seem to be money makers. the cats (especially the c18s) have more power but burn more fuel. break downs are not common theyre both pretty solid. if i was an owner operator it would be a volvo with a cummins over a 379 with a c15 or c18.
Am really enjoying your video,thanks a lot
Dude, you're the man
THAT was the most enlightening information that I've had in a very long time!THANK YOU!!!Just a thought,I wonder does that apply to all BRANDS?Like I said,just a thought!
Thank you as always for sharing your knowledge brother😎
very informative.Thank you.
can you make a video about single turbo conversion?
This was useful in trying to understand why an engine with 775,000 (Mack) might fail if the HP was increased from 415 to 485. FYI, over-runs on the engines were eight with each instance being more than a half hour! Must have been some enormous hills to descend. Again, I am neither a mechanic nor driver so I don't know. But I do know that the only change to the engine in the shop was software - no hardware at all.
I learned a lot. Thanks
trucks and 966 loaders.great engines.
Good Channel and Good video. Keep up the good work, drivers need a Mechanic doing videos from your perspective.
thank you for the info
Very interesting 🤔
Good information, thanks 👍🏽
Really good information, thanks
Thank you for the kind words.
A re-rate here At Blanchard in Summerville SC according to them is 750 for the Cat password to get into the ECM then 2 hrs labor. About a grand. I'll run my c15 475 and like it for a bit longer.
thnx buddy you the man
9-11-2023 Praise our first responders. When I started driving professionally, I was informed to never allow the pyro to hit 1200. I could do very serious damage to the engine. So I held to that reasoning. even though this is 7 years ago It really hits home. These drivers today have no idea what this is about since the computer will not allow it to happen.
If your Cat dealer has dyno I would also recommend a PAR dyno. Just because you engine flash file is for 500hp it doesn't guarantee your engine is producing 500hp. The engine is run on a dyno at the factory when it was build and the fuel rates were adjusted to with in normally 1 or 2 hp of what ever your rating happens to be. In some rare cases after an engine has been fully broken it or is several years old it can be up to 15 to 20hp low at the rated RPM and sometimes even more in the usable RPM range of 1100-1600RPM. If the dealer has a PAR certified dyno they can adjust the fuel rates back up to meet or slightly exceed factory specs for your engine rating. I have always recommended doing a PAR dyno before doing a top end and not after. The reason for this is if you valve lash is on the loose side you are loosing valve lift and reducing hp, when the injector rockers and rollers seat in and start to wear this normally retards timing reducing hp and throttle responce. Doing the PAR dyno before to top end set will compensate for this and bring your hp back up to spec. Then when you have your top end set it will advance the injection timing and the tighter valve lash will increase the valve lift for on average of about a 10hp gain. Not a huge number but in some cases every little bit helps. It might be helpful for some guys if you have a video to better explain what a PAR dyno is. In some cases it may not be available since most dealers don't invest in the required building separate from the shop, the very expensive dyno equipment and the trained technicians to operate it due to the low demand and profit. Hope this helps
I am confirmed.
I read the Pittsburgh Power past articles in a Truck magazine. "Cannot understand why rebuild and not also increase rhe horsepower?" and "The rebuild price is about the same for a. 350HP as it is a 550HP engine" and "Improve fuel mileage" "You only live once'".
I am benefiting from longevity with a low rated 370-435HP Cummins N14 Celect Plus (It is to increase the horsepower and torque in the last two gears only when going up a grade). I do actually feel it kuck in at times. It has 43.5k hours and over one million miles. Day cab undef 4.7k idle hours.
Intermodal also helps: I am not hauling steel or heavy liquids. Most loads I pull are are under 30k lbs net. I am empty 50% of the time.
I do care about gradeability: I just run my low horsepower N14 at 1450-1600 when loaded and chop my way the upper midwest hills. Eaton 13-Speed allows me to stay in the aforementioned range 95% of the time from 20MPH to 65MPH.
I drove and MBE 4000 for a while with a 10-speed. Good low end for the bottom eight gears dow to 1,000. Poor Volvo Detroit lije gradabimity losing 10MPH up 3% grades.
Cats may be the most poweful engine but in my experience they are also rhe most thirsty. I average 6.25-6.5 with my N14.
THANKS
Great vid
Cummins in Amarillo Tx did just that to my 97 freightliner with a N-14. I went from
435hp ( 1600 trany torque ) to
525hp ( 1850 Trany torque ) and daammmmm that’s a beast now. Cost ???? $$$ 350
The highest torque rating you can get is 2050 for the transmissions but trucks at sled pulls put out 3,000 plus foot lbs through these or lower rating transmissions with no problems. It's all about proper use of the transmission.
great video
I love that am look forword to see it
I did a rerate to my 3126. It was gutless, 175hp. Dealer said I could go to 190 with no changes. 210 if I changed the turbo, or 230 if I did the turbo and injectors. I’m sure injectors would’ve been pricey, so I installed a reman turbo. It seemed the only difference was the new turbo has a wastegate. Then I had them do the rerate. It’s still slow, but definitely noticed it has more power.
Garbage engines those 3126s are. How you gonna get 200hp out of 7.2l?
@@benjaminturpin2749 7.2 isn't the problem, it's the design of the engine , it's a natural turd
awesome video, I'm quite interested in hearing more about the tuning end of things with not only Cats but on diesels in general. keep up the good work my friend.
Thank you for the kind words. The tuning on these engines can get pretty intense, but I just wanted to show that there is also a Cat certified alternative to the aftermarket.
i still find it hilarious that you can plug in a computer and load a tune for a 550 or 600 horse C15 onto a motor that originally had 425-435 from the factory. perks of having a Cat versus a Cummins or Detroit lol.
+shortfuse1993 You can do the same with a Cummins or Detroit... js
@@AdeptApe u
Hey what do you recommend for a fuel additive to clean the injectors? If there's such a product out there?
Yeah this what I do to electric Cummins motors, I take em to the Diesel Doctor I'm Effingham, IL and have him turn the motors up via file thru the ECM port. He normally turns em up to max 600hp 2050 ft/lbs torque if it's a non dpf motor or max 550hp 1850 ft/lbs torque for a dpf motor! I just didn't know it was called a rerate!
I'm looking to doing 700 HP with a 6NZ when I get my first cat without screwing up the engine
thanks alot
What are your thoughts on diesel freaks power harness could you maybe do a video on the pros and cons?
Can you please tell me where can I find those re-rate charts at 4:45 in this video? I am looking for the family delineations for my 3406E 5EK. Thanks!
Does rerating require a change in the governor?
I just bought a ecm from goecm for 1375 . Had it in 3 days from when I ordered it .
Very interesting. Is there a camshaft upgrade from a 2277508 that will allow for more horsepower? Thank you in advance
Hi can you explain the science behind re rating the ECM? I mean what components does the ECM command to work differently?
I have a question;
Can I still add the exhaust, turbo, & Banks power-pack on top of this re-write if I have Cat rebuild my engine?
КЕТ РУЛИТ!!! ХОРОШИЙ ДВИГАТЕЛЬ!!! БОЛЬШОЙ РЕСУРС!!!
I built a 3406E for a customer 5Ek was the stock engine family
He wanted a serious up grade and buying all cat parts we put 6nz parts on his engine loaded liners head , cam, injectors and turbo being 19k in parts we had a rerate for the Ecm print out was 550 hp @ 1400+- rpm 1300 +- torque at 1400rpm i think it was a genset file not sure but oh man that truck will pull 100k up hills in sc like nothing else in the area kinda like it doesnt care how much weight it pulls never more that a dark grey cloud of exhaust smoke and clearing right up. The man is super pleased with his engine after 10years. Question educated guess on power at 2300rpms the print out states hp and torque at a very low rpm setting it would be interesting to know what it has at high idle
Adept Ape any recommendations on Detroit Diesel 8.2T turbo??
Can you rerate to the fire/Rv ratings now that the 3126 are beyond any factory warranties? I have a 190hp 3126 in a 2001 C5500 and would like at least to be at the 300/860 mark but more is better. I have seen the PDI tune/turbo/manifold aftermarket options but not sure if worth putting on a such a low HP engine. I assume it would be cheaper just to find a running used engine in the HP range I’m looking for. What do you think is the most cost effective way to change 190hp into 300hp?
I need to know if fuel additive is needed in a 3406b engine, because of low sulfur fuel, and what do you recommend? Thanks!
"Your engine family that is" LOL
Wowzers, you get alot of comments! I don't know how you keep up with them all. I must say that I love your channel. Your devotion to educating others about CAT diesels is really cool! I enjoyed studying the C7 engine family re-rate chart you showed in this video. Do you have a chart of these families for the 3126B/3126E? It would be very interesting to look at (I like numbers!). I'm thinking about buying a bus and considering the T444E and 3126 as possible choices, but it will be a while before I can afford one. I know little about the CAT motors, but I've been learning quite a bit watching your channel.
As a side note...do you ever plan to do a video on how to set the injectors (synchronization) for a 3116? I have no need for this, but just find the topic really interesting. I imagine there aren't that many out there these days, but probably still a few. I know a guy who used to work at a CAT dealership and said they were an awful pain to do. He was the only one in the shop who could (or would) do them.
Thanks for any information you have. Keep up the great videos!
+Jonathan Bopp I used to reply to every comment before, but I don't have enough time for that now. I'm not sure when I'll do a 3116 rack sync video. We only get them about every 6 months, but I'm the lucky guy that gets to do them. They are very tedious to do. It isn't that they are crazy hard it is just a ton of little steps and the Cat instructions are hard to follow.
As far as the 3126 rerate chart, probably won't be putting that up online because it is much more difficult to follow. It is much more component dependent and is several pages long.
I can see where keeping up with so many comments would be time-consuming. I figured you didn't see too many 3116s these days, but I know they are still out there. I rode on a 1995 Bluebird GMC bus for years and it had the 3116. It never failed us, but was a real dog starting out...particularly on a hill. The turbo lag on them (or at least the later models) was something awful. The mechanic I knew said that they used to get that complaint at the dealer constantly. He said they would put the bus in gear and push down the pedal to see how many seconds it took the engine to reach a specific rpm. If the time was too long, there was an adjustment screw you could adjust to turn up the pre-boost fuel. I realize doing a video on that would be tedious and time-consuming. I know the timing of when you get one also might not be at a convenient time to do a vid. From the little I know, the process is vaguely similar to Detroit's "rack" system.
Ah, so it would seem that a re-rate on a 3126 would involve more than than flashing the ECM in most cases. I had just assumed that it was similar to the C7s. If you ever get motivated, I'd still find the chart interesting, even if nobody else did. I love specifications and numbers.
Thanks for all you do for all those who watch. I'm going to send you a donation this evening. :)
Just curious how hard is it turn up 3116 have one in 96 topkick says 170 hp but a tick more would be nice nothing crazy just dab @AdeptApe
Nice moustache
what would injectors run for 6nz c15 3406 engine ? can i get mine rebuilt or dosent it matter as far as seating them back in?
I have a c-15 serial SDP how can I find the chart that you used in this video to see how high I can go with my HP
This is in a 2008 Pete and it had been deleted by 2nd previous owner. Shows 475hp on the computer but KW tech said it could be different HP because it has been deleted is this correct and how can I find out what the HP is?
thank you for your time.
3406 and the c15 do we look at the same family ?
I have a 2005 lexion combine with C9 engine. It's at 360 hp. Can we safely add more hp? Not driving the snot out of it. Just need a boost once in a while
Hey guys! I have a C7 engine family 5CPXH0442HBK with the cylinder head off and the walls on cylinder #3 with some scratches, if not gouges. The original symptoms were huge blowby coming out and blue smoke / oil coming out of the tail pipe. What is weird is that cylinder and head area for cylinder #3 are dry and we found oil on top of the other cylinder / head area. Also, only cylinder #3 exhaust manifold hole is wet of oil and the other ones are dry. Please let me know what are the chances that this engine can be rebuilt, maybe by cutting the walls and putting bigger pistons. Or, what are the margens /specs / limit for cutting the walls. Thank you
Where can I find the charts that you show in this video?
next valves on cat15 I am waiting
good morning adept,I want to thanks you for the videos that you have make us,I really learn alot of things from them,pls can you make video for me,a video of how to drup and engine from the a track☺☺
+raymond idirigbe I happily try to take requests, but I'm not exactly sure what video you are asking for?
Adept Ape I think he was trying to say "drop an engine from a truck"
Im considering buying a 310 catapiller 3406 1992 FREIGHTLINER FLA104, can this be done with this semi truck? Thank you
im looking for a pre emission truck and found a pete 379 with a 3406 5ek engine with 550 hp with new platinum overhaul from cat
would that increase in hp damage engine from overheating. its probably a different pistons pack but all that extra heat
what u think ?
Are you familiar pre emissions Cummins ISX?
Thanks for the great videos. What would it take to increase a 3126 from 230 to 300+?
+george jetzon A 230 hp engine usually has different pistons, injectors, turbo than a 300 engine.
Very nice info. Hey boss, where are you from?. I got 1.3 mill on my pete 379 with cat, c15mxs. Start leaking right next to head. May be you can help me. Can you? Thanks
I have Cat ET at my work. I mostly use it for diagnosing fault codes on C7 Cats in school buses. My dad just bought a 2000 Kenworth with a C-15 6NZ 475 HP engine in it. He is complaining about the lack of pulling power in it compared to his old 3406C. Am I able to rerate his engine for him with my basic Cat ET program? If so, do you think you could make a video of it? Or at least explain where to find it in ET? I don’t work on Cat much, usually Cummins. On a Cummins I would just download a file from QuickServe.
Hi I have C 13 industrial engine and it runs for 5 years without service
C13 AND 3306B HAVE SIMILAR PARTS ON VALVES SETS AND VALVE STAM.
Just bought another MBN C15, @ 435HP. Had CAT turn it up to 525HP, as it states on the passenger side of the motor. You have to find the right CAT tech for the job, because I've found out that most guys won't do it.
+sTEVAL570 I think many people are intimidated about it, unless you've done it before it can seem hard to find the information to do a rerate.
Adept Ape thanks for video . I have c15 6ng single turbo . My fuel mileage is around 4 mpg . I put new turbo and manifold by cat but fuel mileage is still 4 mpg . Need some help
Clean the soot🤔
I just bought a 2004 Monaco motor home with a ISL Cummings 370 me have found no maintenance records so I will be doing a complete Oil and filter change to include fuel filters and such. The Engine has 67k miles what Oil should i start out with.
How do you clean the turbo oil drain pipe
How about a motorhome Cummins 8.3L engine, is it the same process?
Can you do a rewrite on a Cummins isx 2012 ?
Ok...am i the only saw that lady walked across the room @7:59m
What can I do to get more hill pulling power out of my 3208T? It's in a motorhome, pulling hills can be a pain, struggling at 35 mph on some hills.. bigger turbo? Fuel adjustment?
What if you add or install aftermarket bullydog tuner
What do u think we'll happen if I but a cat 3406e turbo on a cat3406 b
Where does the the tachometer cable plugs into?
I am going to be rebuilding my c7 in my c7500. I would like to build it up to the c7 360hp spec. Would you know where I could find this info?
Got a 550e 1999 in a kw blue turbo up wanting to upgrade it any suggestions
Looking for some help on a fuel issue on a 3406 b model
I work for Finning/CAT in Canada. I've been toying with the idea of throwing a 3126 or C7 in a pickup as I've already put a 6BT cummins in an F350 and want to try something different. From what I've seen, these engines highest ratings are for emergency vehicles and is around 330/350hp, but the marine engines are rated at somewhere around 450hp. Do you think it's possible to get the software for the marine engines to work on an industrial? I know cooling capabilities is probably the biggest issue but I'm just curious. My end goal would be making somewhere north of 500hp with compound turbos and whatever mechanical fuel modifications I could do.
+Max Mcrae I think the best way to go about it would be getting a marine engine to start with because the injectors, turbo, software, cam, and pistons are probably all different. Then you just need your throttle, cruise....Etc inputs.
Ive heard of a place that hired a mechanic that worked at and was trained by CAT and he is rerating many of their trucks. Is this possible since the codes have to be purchased from CAT?
friend, good morning
Could you sell me that list that shows the specifications according to the engine ...
Cheers
HI i am wanting to re-rate my c7 caterpillar engine and i have a cat on my computer im not sure how to go in and re-rate it thanks if you can hlep out and keep up the good work.
I have an old 3406b, I’ve watched most of your videos but haven’t seen what you have described as my issue. The turbo wasn’t getting the boost it’s supposed to, so I changed the turbo, before watching your video. It helped a little but still not what it was. The motor rpms seem to rise fast without building boost. Changing fuel filter and air filter and still nothing. No fuel leaks either. What should the fuel pressure be on these? Above 80 psi??
Look for leaks in your turbo/intercooler system, hose, condenser and anything else that's attached
Sorry buddy just saw that you asked that question 2 yrs ago
What if your engine is already getting close to rebuild time?
Where did you get the charts for Hp specs
Forgive me, I know you get a million questions! If you don't have time, maybe some of the other guys can help. I'm try to find information on the best operating rpm range for a 2001 C-15 6NZ single turbo pre-emission. I'm averaging 6.0 mpg and normally keep it around 1400 rpm's in whatever gear for the speed limit and try not to let it get over 1800 rpms under jake down hill. I'm looking at a chart for horsepower put out by "Road Choice" Truck parts online and it references a 500 hp testing at 2100 rpm's putting out 1850 ft lbs. 2100 is not a working range is it??!! Again we truly appreciate all that you do for us!!
Peak torque is at 1200 rpm. If I remember right 2120 rpm will be your top engine speed limit. You get your torque down low and your horsepower up high. A lot of people dont want to lug the engine but a C-15 can take it, and really its where the torque is. If its running right you shouldn't have no problem pulling right out of it. Generally keeping the rpm low most of the time is gonna make the engine last longer. I overhauled one for a guy one time who kept his rpm low and changed oil religiously. It had over a million miles on it and the rod and main bearings looked brand new. 6NZ is a legend so make sure you hang on to it and keep rebuilding it.
A ecm comes a dime a dozen. Just need to know the right people. I goto computer king in Dickinson tx. They warranty everything. And if you have a faulty one, they’ll hook it up to they’re truck. But I had a faulty one and came out at $850 with core.
Zeigler CAT of Rochester, Minnesota says that they don't/won't do a re-rate. States that CAT "won't allow us to." Is this common? They sent me next door to Rochester Diesel. They say 100HP for @ $2000 parts/labor. That seems odd. It's a 2000 3126 f650 that started out as a 26' box truck , shortened & now has an f350 box. It's just a big toy I use to tow my 42' travel trailer a couple times a year. Not sure now exactly what to do. I'm just looking for an improvement in fuel economy. Any suggestions?
That's a pretty high chance
Where is your shop located?
QQ:Hello Josh what do you think about change in a camshaft to a marine c18 camshaft would that give more horsepower to a c15 or 3406e? Thanks
It would hurt more than it would help without changing injectors, pistons, turbo, and flash file too. A C15 (MXS/NXS) can be built back to 625 hp and 2050 ft.lbs of torque though. Ive done three or four that way so far.
I'm trying to re rate a CAT 475 15L 2 turbos, I have the ET software and sis but idk where to start
Hey I just got a cat 3176 with 350 hp where can I check if can be rétate to a least 400hp if possible thanks
Wanting to do this on a 2004 c12 can you help me out with finding the charts or anything
What is the difference between a 3406 and a 3406b cat
anything I can do to up the power of a 1993 cat 3176? the company wont spend the money. the thing is downright dangerous because it cant hang with the speed of other trucks. most it grosses is 45k. air and fuel filters are new. thx
I have a problem with a truck I am working on and $3600 and counting haven't been able to get it running . Is there a contact or place I can get in touch with you regarding this truck . 2006 F650 C7 Acert engine - replaced cam, cam followers , rod bearings , crank bearings, oil pump , 3 ecm's , engine wiring harness
what is the main difference between the software within the same family? do cat raise the oil pressure to get more power and perhaps some duration? surely you've looked at some data and noticed something ! thanks and great videos!
+Turners Garage Its really all fuel. Since the oil pressure is controlled by the oil pump and bearing clearances there isn't much software can do to affect it. It can affect the fuel rate though. If you do a rerate you'll notice that the rated fuel limit will change, which means the engine can inject more fuel which means more power.
ahh i see, i miss understood how the system worked i assumed it would be similar to an isuzu 4jx1 engine i run that apparently has an injection system designed by cat, which is heui but has a rail pressure control valve on the pump which can control rail pressure. i am very keen on getting to know this type of injection system better as i remap a lot of new holland foragers and recently i have been asked to look into a c18 powered one which obviously i will approach with great caution!
I have cat et can i rerate a 3176 from 275 to 350? Do I still need a file to upload? If I had another 3176 that I can pull the data from could I right that to my ecu?
I have a 2009 peterbilt 367 sdp cat c15 and I'm changing the starter but lost the wires and I don't know what to do ive called peterbilt and they don't have a diagram for it just wondering if you had any ideas? I would really appreciate it
