That is a beautiful truck, where I live they are just a memory. Back in High school you either dreamed of a 12 valve Cumins or a 7.3 with a turbo.

[@thesunflowchannel1995]

I dreamed of a 12 valve in high school. Now I own one.

[@Fassfords]

David Does I’m tryna do the same

[@warrenmcelroy4718]

Yeah when I was in school we ran Old Ford HighBoys and idi diesels, some of the more unfortunate guys drove square body Chevrolets haha. My senior year I bought an ‘84 F250 4x4 with a 6.9 and a 4spd and that was one sharp truck, but, thanks to a blown head gasket I drove my uncles 93 F250 4x4 that had a ZF5 and a 7.3 Turbo. I remember picking my buddy up on the way to school and some dude was driving slow as hell up a pretty long, steep hill so I went to fourth gear and passed him “on the hill” and my buddy looked at me with his eyes wide open and said “Damn this thing picks UP speed on a hill!!”... we had a pretty good laugh cause there was NO passing anybody when going up a hill with the old 6.9 hahaha. The P-Pump 12 valves came out in 94 but around here people didn’t really start juicing them up till around ‘99 and 2000, those P-Pump trucks were one hell of a game changer

[@nicholascravens6674]

P.s I had the AFC live on my other truck and loved it. I still have the truck but it’s been in a crash that took it off the road. I definitely liked the 12 valve 5 speed manual better than the 24v with with the automatic. I’m considering swapping out drive trains.

[@johnlong384]

Nice info-video - thanks for that. I did play (~300 hp) with my '97 Cummins, 2WD, 5-speed manual and pulled (too) heavy loads, close to 22K total trailer wight and yes, the truck pulled pretty good but it started to eat tranny's. I saw that you took a heavier clutch disk but haven't heard anything about the NV 4500 and like to know if you suggest to do any changes to the gear box too? Thanks again and take care!

[@utdesertghost199]

Just ran across this video and was curious what the mods you have done in this video would cost and if there are any other mods needed to ensure reliability and durability with the added power.

[@lowellmiller6663]

Thanks for the excellent video! I have used two of those clutches from South Bend and they are a bit stiff on the pedal especially for all the city driving I do. If you drop down to the 400 hp clutch it's a softer and more stock like pedal. I'm also curious what was the boost numbers you needed to achieve that horsepower/torque level. I've had my share of blown head gaskets on stock turbos and head studs. I've blown 2 head gaskets at 40 PSI on stock head bolts and two at 40 PSI with head studs. 17* timing. Needless to say I made some upgrades. 🙂

I will continue watching no harm done I hope just personal opinions I’m curious to see what will come of this I currently drive a Ford F-150 with 300,000 original miles with its original motor who nows I might decide to drop a cummins in it but I thank you for the clear explanation of everything it does make a little more sense my apologies non the less great sounding CUMMINS ...

[@ryanc6574]

Careful swapping a Cummins into a half-ton, a fully dressed 12 Valve weighs over 1,200 lbs! A 4BT could probably safely work & still have more torque than your 5.4 Triton, while also nearly doubling your MPG's.

[@cubpak89]

You should do a video on how to do the fuel timing please. You speed by that part

[@sjfodor]

Great video for possibilities for a 12V, but not super helpful for a diy guy. Would be nice if you did several videos that detailed the steps of what you are doing other than here is what we are going to do and three seconds later, “it’s done” next step.

[@arriviste2020]

Interesting video. Just a coup;le of questions. What do you lose in the conversion? Increased Horse Power doesn't come free.Injection timing, has this been set up on an apparatus similar in concept to a Hartridge machine? Original Injector timing has been set to gain max burning of fuel at the moment of injection. Plus all injectors are bench tested and pre-set, equi spray patterns verified and formation of sprays checked inc delivery pressure to each injector.Spray patterns checked and delivery valve closure verified for efficiency and leakage.That plus the spray pattern of the injector determines the efficient generation of power from the cylinder. If the injection phase is early, then the flame travel / ignition will be early which immediately has a slowing effect on the piston travel. With all that in mind, what exactly has been lost, in able to gain the figures which are quoted? I am not slagging it off, just curious.The engine has been rated at a Horse Power for given RPM, increasing the RPM, unless original dyno info is available does not necessarily mean an increase in Brake Horsepower.. Again, I am just curious.

[@tedtolentino4955]

Thank you for this video; great information. What would be the cost these days for all the upgrades (minus labor cost) you show in this video to achieve the power numbers on the 12-valve Cummins?

[@pddofficial]

Around $3400 with clutch,exhaust,intake powerdrivendiesel.com/product/diesel-tech-fuel-package/

[@F350JOHN]

Had Dean opted to purchase a performance turbo, which one would you have recommended with your 400HP kit, and what kind of gains would it bring? Thanks.

[@daeljuma]

I have a 97 Newmar front diesel powered by a 6BT and running an Allison 5 speed transmission. Would these upgrades work on my engine?

[@emeraldstevens8922]

Would these kits work in a marine application for example 210 HP 6bt Cummins

[@martinsinclair55]

That was a 25 year old truck. How much did it cost to get that extra HP? What if you have the stock auto transmission for 95? Can it support the extra power?

[@ms.karihart2983]

Question Could you re-gear first to 35 inch tires. I’m not real sure on adding gadgets to make my 97 Ram 4x4 , it’s automatic transmission. I would like to double the horsepower for a stock truck , hauling & towing and occasional cruise night

[@AlzWorld57]

! did a few of these things to my truck and the biggest problem now is axle wrap when pulling my 5th wheel up a steep long hill...the engine wants to go but the tires are gripping to tight...traction bars/ladder bars are next I guess...

[@stiffass9539]

In your horsepower doubling series, I think it would be cool to see if it was possible on the older IDI engines like the 6.2 or 6.5

[@jonathanstansell8511]

those engines can barely hold together in stock form. hardly anyone upgrades them. much more potential out of a 6bt

[@USER-fd-me1ep]

Hey, Guys Love the channel! I have a 1993 Winnebago Vectra with a 230Hp 5.9 12 valve in it that I use to tow our race car trailer. the motorhome and trailer loaded weighs roughly 30-35,000 lbs Any suggestions how to gain a little bit of power? I'm not looking for anything huge but, some power to help it get up the hills a little better would be great.

[@recrdholdr]

With my motorhome being a diesel pusher, would the length of the tubing(30+ feet) affect the APC Live? I know it would affect a mechanical boost gauge aka slow response.

[@tigerseye73]

If you youngsters want a racing truck, put a turb'd Viper v-10 in it. Trucks are made for hauling. Not HAULIN'. My stock '97 12v has never failed to easily pull any load I've ever put in it. When I want to drag race, I bring out my 2.5L Dodge turbo powered trike.

[@shanee3766]

I need a 4k Gsk kit and 60lb valve spring full tutorial from you guys.

[@JJZBULLITT109]

Valve spring install is very straight forward. The gsk is a little trickier, one because in situ it can be a bit like playing operation with the springs and shims. A dixie cup with the bottom cut out, a hook and magnet make that much safer from dropping anything into the pump. Setting up the spring preload is up to you. Some guys go by clicks, others (like me) use a caliper.

[@shanee3766]

I figured that out since then and I picked my truck up today built 47re now... stoked triple disc billet input/flex plate/gear band, ect... So I need the 4k gov's because of the low stall I think it will help. its bone stock right now putting afclive on tmrw.

[@jonathanharger7430]

toadamine you can build the auto to handle over a thousand horsepower it’s not hard and it’s not really crazy expensive all diesel auto trans are really not built to handle more then stock some can barely handle stock

[@JC-gw3yo]

How about testing with an aftermarket intake/air filter. As the exhaust has been updated, how about the intake side ?

Would you need to upgrade your clutch if you got a decent turbo and intake system

Dont even need to do any kf thoes upgrades to add much more power. Just tweak to p pump and there ya go more power.

[@handmethatchingadera]

Could these modifications be applied to a marine 6bt in a boat? I mean obviously the exhaust would be watercooled and not really be changeable but the fuel control I would think would be ideal to be able to cut back for economic cruising or tournament day offshore hammer down.
