- I finally put my 1996 Dodge Ram 3500 on a Dyno to see how much power it's making!

Thanks for watching! - Auta a dopravní prostředky
I'll be happy with 350hp to 400hp out of my 1998 12 valve 4x4 5 speed lol 😅
Yep that’s a good driver!
Nice dyno pulls! Those are good realistic numbers for a good driving truck. You’ll break 600 no problem once you work the bugs out and start tuning.
Thanks man!
Good job explaining your logic. Appreciate the video. Cool rig as well.
Thank you!
Not to knock the setup at all but you'll unlock a good amount amount HP without losing much response with the use of a larger primary without one of the typically used larger turbines(96/88 clipped wheel being the worse which is used nearly everytime). The s369's are great for a tow rig at high elevation but if you're going for power a s472 or 75 with 83/74 or 87/82 turbine wheel and 1.10 T6 housing.
Thanks I appreciate the info. I have a 1954 Mack B20p that I will be swapping a 12 Valve into. That will be more of a high hp build and I’ll keepbthat in mind.
@Micheal
That’s not true. PDD already tested the k27/s472 on Wills truck and proved its only 10-15hp better.
Limit is the k27 turbine side….
On my PDD kit,I use a SXE 372 w/ 1.10 t4 housing instead of the sxe369 w/ 1.0 t4 used in stocky baldmans kit.
@Drew Sharpe I'll have to find that test. Was it on CZcams or the forums? The thing is you're spending $2-300 more in the case of the s369 and $4-500 more in the case of the s372 and giving up durability and power potential to the S472 without taking much of a penalty in spool up. Unless you high elevation and not going for a bunch of power it's fine but the simplicity of primary being an s400 is tough to beat.
Getter done👍
👍👍👍
I have the same build going. Good to see the progress and issues you've come across so I can better prepare. Are you towing heavy with this?
Awesome! At some point I would like to get a camper and tow a medium sized trailer. It will be loaded down pretty good especially considering how many steep hills there are around BC.
Can’t remember, do you have 4K gov springs and bigger delivery valves? I’d say the numbers you got are respectable given your big tires. Not only do you have big tires but you’ve got 4 big heavy tires to push. If you wanted to cheat, next time pull the outer duals off and run it that way. And I agree about the cam.
Ya I’ve got what Power Driven Diesel calls their 7mm delivery valve and 3/4k govenor springs. I plan on doing a bunch of test videos on the Dyno. Definitely gonna do one where I just throw two stock sized tires on there just to see how much power I’m losing with the 37” duals
My 12 v did 553 HP 1305 tq with compounds 😊
Awesome!
I spent 17k on upgrading my Duramax, I'm here to see what it takes to get a Cummins built right. Seems like the Cummins is more expensive because the front end. Cummins is better overall and overtime though.
Awesome, Ya I think they are both pretty capable platforms.
I'm curious which radiator you went with? Would love to see you do a run up a steep mountain towing before and after the new radiator for comparison!
I had to just bite the bullet and get a stock one for now. I am definitely going to go with the cold case based on your recommendation. I will definitely do a comparison between the stock style and that one when I get it. I just have to get this truck done and stop spending money on it. 😆😆😆
@@StockyBaldmanI'm to the same point with mine!
I almost went for the Mishimoto but I think that big dual core rad from cold Case is the way to go. Thanks again for the recommendation!
@@StockyBaldman absolutely!
Clamp is too big. Should not be touching...
Awesome that’s good to know!
I'm guessing it's going to make 675hp.
I was thinking right about the same
YOU NEED a different clamp
You are correct, it has been replaced now. Made an immediate difference
Tires robbing you of some . Noticed big difference going from 29 to 33 on my f350 diesel .
Yeah I bet, I’ve often wondered how much power I’m losing with 37 inch duals
What size wheels and tires are on that rig? I have the same rig
Awesome, they are 37x11.5r20 Nitto Trail Grapplers. Rims are 20x8.25 XD Machete
Thanks for replying with info.
Absolutely, thanks for watching
Wonder if putting 2 valve cover breathers and sealing up the tappet cover completely would help get ride of your oil leaks. It’s what Will at PDD is doing with his new build.
I was crawling around under the truck today, the leak is actually coming from the vacuum pump. But you’re right I was wondering about getting some more venting in the system. Possibly changing out the oil filler cap at the very least
Vaccumm pump will definitely be an easier fix than the tappet cover. Venting through the oil fill cap is a good idea to
Yeah I rebuilt the vacuum pump, or I should say I resealed it it was a doorman kit and the main seal never really seated in there that will. I have had problems with it leaking from the get go. I might have to go to Cummins and get a proper kit
Curious how the vacuum pump relieves crankcase pressure? Mine leaks too, but ill get to it.
I think it’s more than the vacuum pump when it’s leaking can put pressure in the crank case
What gears are in the diffs?
Stock was 3.55 but I put in 4.11s and air lockers front and rear
@@StockyBaldman bet you'd get your number with 4.56's
Yeah if I had to do it again I’d probably go with 430s or 456s
Why is your idle so high?
I think technically it’s still too low. I think it’s currently at about 650 to 750 rpm in Drive at idle. Probably should be 850 - 900 from what I’ve read
When it’s in neutral tho it’s around a thousand wasn’t it?
Those are good numbers tho you can’t turn your nose up at 1200 just shy of 1300 ft lbs. That will be all kinds of fun to drive.
Yeah even higher maybe like 1100. I wonder if that’s a sign the bands are tight it really bugs the engine down a lot when I put it into gear. Possibly it’s the triple disc torque converter I’m not sure but it’s always been that way
Yeah totally the thing is an absolute beauty to drive
Another $100k and you’ll probably be leak free.
😆😆😆 I was crawling around under there today I’m pretty sure the leak is coming from the vacuum pump.
Word of the day is dramatic.. smh
