- BEST FIRST PPUMP 12V CUMMINS MODS !!!
DOING THESE MODS FIRST WILL MAKE YOUR PPUMP 12V CUMMINS A HOLE NEW BEAST TO DRIVE. THESE ARENT FREE MODS BUT FOR THE SMALL INVESTMENST I WTHIN IT WELL WORTH THE MONEY
The best mod I ever did after the dowel pin was timing for mileage . I run 17. 5 or 18 . Huge difference in mileage . The mods you recommended I done also along with the 215 injectors and the thin washers . I really appreciate your videos .
Great to hear!
thin washers? what are those for
Diamond eye has a very reasonable exhaust. It has lasted me,in salt country and running in it, 4 years,but I cleaned and painted the non stainless one. But, Rob, I wish you were around years ago when I got started into diesels. Great info man for alot of guys who are getting started.
Yes diamond eye is a good option. I was again just not on videos yet. I wanted to be on you tube 5-6 years ago. But just never made myself do it.
10/4 on the gov springs. Had a ‘94 manual trans, deleted the fuel plate first and was somewhat disappointed that the power increase wasn’t bigger. Then I did 3k springs. WOW did she wake up. Felt like twice the horsepower
Yep beat first mod
No kidding that 22 degrees of timing makes it hard to start in winter lol great video Rob thanks for putting them out!
Thanks for watching.
Great content thanks😊
I will follow your advise on what to do. First I want to add gauges then all the nice stuff you mentioned. Thank you again. Keep up the awesome videos.
Thanks for watching.
Did 4k and lightened the valve train with Hamilton 165 spring kit, while I was in there did the pushrod cover seal and slid my fuel plate forward. World of difference!!!
Next summer is the nv4500.....5th gear
sure does
Mine is in the middle
Great video liked how you laid out the mods.
😬🙏
Awesome video, thanks for sharing
Well said.
🙏
Love you bro not that gay stuff your doing a good job thanks for the info
Thanks man. I appreciate the support.
3k.... don't have to worry about valve springs stock can handle?
If you had to take a guess, at which number will you put the power after this mods? Great video.
Hard to tell. The rpm springs don’t really add power just change the power curve
what brand govenor Springs and valve Springs do you recommend
I use pac brake a lot as they are easy for me to get
@@CUTTERUPROB man I truly appreciate you responding back to pretty much every single question. Beyond thankful for your time and knowledge.... just pinned the KDP today! Tomorrow will be the front crank seal and zip everything back together
@@Electrictheater9 I do my best to ask every comment. But it’s getting hard lol
@@CUTTERUPROB Oh I can only imagine, it's a full time job! You're doing an amazing job just keep doing your thing man... this is my 1st cummins and 12 valve so you've helped me so much already
👍👍 right on man
🙏
Do you think these mods can improve mpgs for towing. If not what would ? On the pump side ofcourse
I will be doing some mpg stuff in the next couple months. That said answer some questions
I just watch your video over n over, my 97 fl60 frightliner cabriolet, has 71k and p pump max rpm is 2500, I need more out of it. But safe conservative ish, what do you think I start
To start I would do
Governor spring kit 3k to start
Add some timing to 16-17
Move you fuel plate ahead, just make you you keep an eye on the egt’s
@CUTTERUP ROB I'm a bit confused as to how to timing 16-17 advance, is that moving the plate towards the rad or that wheel turning to the motor?
Ok I see a bunch of #0 to #11 fuel plate , what would be a safe number to go with
What fuel plate did you go with or what all did you do with your truck? We have a rollback with a 12 v Cummins and Eaton 5 speed.
@@peterdelfs6211 I ordered akit with o plate and springs, 3k , im going to do install when weather gets better and I watch 1k more videos lol
You never mentioned changing the spring in the Lift Pump on a 12 Valve?
Will be in the next video
Can we use 4K governor springs with factory valve springs ?
you can , but you can float valves and is the boost / drive pressure is high you have have issue with power loss
new to tuning 12 valves- i purchased a 97 and it came with the "adjuster by attitude" cable operated rack adjuster.. whats your view on it? go/no go? I got a ton of stuff to build this 12 valve too
They do work. But limit the over all rack travel. So depends on how much power you want
@@CUTTERUPROB im looking to do a complete rebuild soon. Depending on wear in cylinders- a freshen up on short block.. i got a brand new head, if i can squeeze 400-450 hp out of it with a compound setup- stick with a stock grind cam or a stage 1 or 2? Its going to be a daily/ tow truck for my race car trailer and a few heavy hauls.
Thanks for your reply. Any input is greatly appreciated.
Im no stranger to the automotive machine shop so i am mechanically inclined
Do you max and balance pumps from the US if mailed to you?
I don't in house, i would call seth @ farrell diesel service
Where do I get the AFC kit with washer and spring?
as it stands i dont have them for sale , but when my website is up they will be on there
I put 4k's in my 175 pump and torque still drops like a rock at 2800rpm. 18* of timing. Fuel pressure 45psi Airdog 165. Do I need DV's too? Should I just get a 215 pump?
Overflow valve in good condition?
@@witcher71tork tek ofv60 brand new.
Can you free rev the engine too 4000k ?
45psi at WOT?
What the rest of the set up
@@CUTTERUPROB 45psi at WOT, Free revs to 4000 no problem. 103lb valve springs, pushrods, hx35/475, hamilton head, tork tek OFV60. 7x0.010 vco's. benched/maxed pump, mack plug, afclive, stock DVs. torque goes from 1000ftlb at 2400rpm to 400ftlb at 2900rpm. Edited: peak torque was lower rpm
