You are the man! I wish more guys in the Facebook Fummins groups would watch you! Everyone wants big compound setups, big injectors, and the engine runs like crap or the EGT’s are through the roof! Thanks for all the videos Rob! Also, thank your wife for being patient!😂 Much love brother❤
Ya. The up coming dyno series should help that some and the new better cameras and editing the comes with it lol.
My wife is a angel that is for sure
Great video! It really shows the difference / advantages for the max travel kit!! Keep it up!!
Many thanks for this and your other videos. Totally new to the 6BT and P-pumps. I am in the (slow) process of converting an old Bedford 4x4 firetruck to a 6BT and Allison 2500 auto here in Australia. While powering up my 6BT (a 215hp UK built engine ) is not an immediate concern (it represents a doubling of Hp and Torque over the original petrol/gas engine), your videos are helping me understand what does what etc. Cheers from Oz and thanks again. Greg
Thanks for watching
I appreciate the time and willingness to share your knowledge and experience in every video I have seen you do.
I have heard to talk about this bench setup before and FINALLY found this video which shows how. I did a few of the mods already but have not done the spring yet. Next on the list. My 47RE has just been rebuilt and my transmission guy has the foresight to ask if I am going to put more power to it than stock. OF COURSE I am. So, he put some extra goodies to handle the mods.
Your videos are my go to for my 96 5.9 I have been subscribed ever since I found you, keep up the good work.
Thanks brother I appreciate it
@@CUTTERUPROB hey Rob have you made a video on breaking in a rebuilt engine properly if so can hit me up w the link
Great video on this mod. Thanks😊
🙏
Expand vary well thanks will be doing this
Great video valuable information.
🙏
Great video 👍🏼
🙏
Excellent
Good stuff Rob👍👍...I've got AFC live on a daily driver/ grocery getter...I like it I guess... The turbo I have on it at the present time is the main issue .... would like to try some kind of VGT ,but.. we'll see...but anyway..👍👍
It’s a slippery slope. Fule then air then fuel then more air lol
Great idea for a video. Trying to envision how it all works while the pumps on the truck is a little difficult.
🙏
Great info for the new guys out there. I've done all the mods, but didnt put the max travel nut on because forums and such say not to put it on a 215hp pump...is that true? Anyone else have any comment because Rob asked us not to do this.
With the 215 pump you have to watch the travel doesn’t go to far as the you will loose powe r
Great videos....... Is there any reason to do this mod and spring change with the 180hp pump #8 fuel plate installed, stock injectors, BHAF filter and an automatic transmission? I'm looking to get better power while towing with 3.54 gears. Runs well now but of course who doesn't want more power?
just adds a bit more control with the afc
so what's more travel of the rack actualy do? more rpms or more fuel or what?
Thanks Rob good stuff. I'm having troubles after doing the max travel kit ,and other mods. My pedel is hard to push until the rpms go up. Assuming it has nothing to do with my linkage. Do you think that's related to the AFC or governor adjustment. I was having trouble getting the smoke out so I turned everything down, AFC all the way back, smoke screw all the way out. As soon as I hit 1 lb of boost it's crazy powerful but very doggy off the line and still a little smokey.
Have to do the afc tuning. Your holding the fuel back to the afc moves. Play with how the afc is located and the star wheel
Thanks that did it! Now it's fast off the line and faster when the boost kicks in. It's hard to keep the tires on the road.😎
Are you going to be selling the max travel kits soon? I couldn’t find it on your website.
yes i wil be
I have a 97 5.9 cummings 12 valve,4inch exhaust,0plane fuel plate,spindle all way out,havnt done smoke screw yet,Cant hear turbo, unless air cleaner off,help
If it’s stock filter setup take that off use a different one then you should
Thanks for posting. I pushed the AFC all the way back to the rear, released all the spring tension on the star wheel and backed the pre-boost screw out until it just touches. But it won't crank in this position. Had to crank in the pre-boost screw about 2-1/2 turns before it would crank. Is this normal? Even full throttle would not crank until I turned in the pre-boost screw.
What you did went in the complete opposite direction of what you want to do for performance and power
@@mattleonard5268 I have performed all the max travel mods outlined in this video. Did I not hear Rob tell us with the increased travel, we can move it to the rear for more adjustability?
Just slide the afc a head bit. Some of it depends how the pump is set up
@@CUTTERUPROB Thanks for the information!
I just bought a truck, took the AFC housing off. No fuel plate at all and AFC is gutted what is your take on this, should I change it
Get a different afc or the pets to fix it. It will make more power with it working. Now I have to dyno they’re will be videos on this kind of thing
i got just under 15mm when i modded mine. i have thought about trying to get the starting point farther back. i think that’s where your getting more than me. i wonder what the difference is.. with my smoke screw all the way out the diaphragm is just neutral. i wonder how your getting a starting position a bit farther back than me. hmm. did you grind the raised ridge on the inside of the afc cap? the small ridge around the smoke screw on the inside?
Did you get rid of the cup washer and grind the foot?
Also depends on the part number of the android. And flatb washers on both sides
@@nategunn2830 I ground the barrel on the foot yes. Max travel looks to be at the same ending point as me.. But my starting point is not that far back. i ground lip off washer. i know some guys use thin washers. gonna have to dig back in.
@@CUTTERUPROB i think i used the stock washer and ground off lip. but maybe two thin washers is better. i will have to dig back in.
@@CUTTERUPROB it was my afc i modded off my 160 pump. i never knew there was different AFC housings. interesting.
What’s your take on afc live ? You think it’s worth it ? Does it really work? For towing! Be nice if you had one there to see in action!
They work. A regular and switch and a needle valve
What do you do with the wastegate on a stock turbo if you’re running this afc setup?
Depends on what your doing with the truck. Most of the time tight it till it opens around 38psi. If you can keep it cool at that point then you need more turbo
Right on thanks
Do you have the max travel modded afc available for a customer to buy and direct bolt in swap for easy power?
I don’t sorry
You could make money on selling max travel modded afc’s with core exchange
If i did the max travel mod, but not the rack plug would it still serve its purpose? or is it pointless to do the max travel mod and keep the stock rack plug?
You don't have to do the max rack plug it just gives you a little more travel. You can still produce crazy power without it
Nate answered it right. The plug will just limit a couple mm of travel
Probably a stupid question, but does this apply to VE pump?
What are your thoughts on fuel plates? No fuel plate? #0? Or #100?
I like the 100 plate for most things
Maybe a stupid question, does this apply at all to VE pump?
Kind of. I will be doing some ve stuff shortly I will explain
wouldnt having a broader fuel range through the boost range improve efficiency? full fuel at 20 psi sounds like a huge waste. especially if unloaded. i want a powerful truck, but i also wanna keep it to where i can just drive and have as best efficiency as possible
In a stock engine you want to fuel to be full fuel around 20psi. As they only build 25-27 psi of boost stock. I set performance ones 40-50 psi depending on the setup.
Does the same apply to the 4bt pump ?
It would yes
Do you sale a afc mod kit
As of right now no. I will in the next few months. Now I have the dummy o I have put all my sale on hold so I can do testing
Your shorty project is taking forever got bummed out it was taking so long a year ago ever happens to slow
Ya your telling me. Lol. I have reordered a few things i need to get this thing done so I can get on to the next project.
