- Let’s get in-depth on many of the different configurations of the Goerend torque converters and how to choose which is best for YOU! #cummins #diesel #transmission #47rh #47re #48re
Killer video and if this helps others
Both rigs p7100 12v’s
One runs a 1500 stall converter but has a 60/67/6cm turbo and I haven’t really found out where it stalls yet. I have taken it to 2300 rpms against the breaks. And at cruise lock vs unlocked is a 5mph difference. About 250 rpms.
The other truck has a 2300 stall but has big fuel big turbo and a ton of timing advance, “sled pulling truck” and stalls at 1800 rpms.
Definitely two extremes but it is a very clear view of torque production vs stall speed to help with your video :)
Great real world comparisons! I’m pinning this to the top!
@@LoganbuiltRaceShop 🙇♂️ it is one of those things that’s kinda hard to see until you get to experience it.
Outstanding video. Very underrated channel. C’mon people comment and like and all that algorithmic stuff so our boy can blow up. I was the diesel tech for Chrysler for 10 years and I always learn something from these videos.
Thank you! Glad you enjoy the videos!
Adding a additional comment. Changing turbine housings on my 97, nothing else, the 1600 stall can almost catch and hold the low stall speed vs the smaller housings that can push right through without any noticeable effect. It starts to get a little sluggish during the stage and wants to hang with the 12cm .70 housing before pushing through. So the motor has reduced in torque production enough to Almost let the converter catch and hold it. I found this fun and interesting. My motor is not relatable to too many but it was neat having one single change making that large of a effect.
These comments are awesome! I hope lots of people read these!
Best vids i have eatched and the best info ive found on any channel now i just need the guts to bould my own trans
Thanks! Have you checked out my Loganbuilt DIY kit build series playlist?
Great information! I'm really impressed! I live near Cincinnati! I want to meet and talk! There's certain things you said in this video that really show you know what you're talking about! How Ling have you been doing this? The way I'm starting to understand it is very comparable to a turbo? It has a sweet spot ect.. the stator the weight ect!
Another great informative video!
Thanks for the info. Very interesting stuff.
That sexy bolt together converter almost makes me want to put an automatic in old yellow but the trans would cost more than the truck and that would make me feel weird. LOL Guess I will have to keep the handshaker.
Technically, there is a crossover from stall to efficiency before you would go to lock up. While yes, an overwhelming majority of stator designs
(which are technically reactors, not stators as they move) ken play a role in making the lock up work harder as they reduce the efficiency of the fluid coupling as engine rpm increases. However, there have been designs that offer a higher star, without compromising efficiency done through usually pump and turbine modifications, which therefore don’t play as much as an affect of how much you’re asking the lock up clutches to do.
Going to lock up later if you have reasonable efficiency would help, but every Cummins owner wants to lock up as soon as possible to load the chargers which at that point you’re not getting any fluid coupling and relying solely on the lockup surfaces.
Why our elders decided to stop calling them reactors and go back to calling them stators is beyond me, but in all torque converter patterns by the OEMs, they use the word reactors. 🤷🏼
This video is 🔥
I'm wanting to rebuild my transmission from my stock 2004 Dodge Ram 2500 with the 5.9 cummins (48re transmission)
I pull heavy loads often, so I'm looking for the right conver.. should I use triple disc?
i just got a 48re tonight also have a 47re for the mild first gen 48 for race hot street burnout fun 13mil daily yes im crazy fmvb rompage i will call soon from ct
Do you plan on doing anything for the 68rfe?
As far as doing 68 builds no. I have moved my transmission builds towards high performance, 1000+hp and racing/Motorsports builds. The 68 just isn’t a great platform for a performance transmission.
Whats the stall for a 18ss?
Every engine/truck combo is going to have a different actual “stall speed” but speaking in laments diesel terms around 23-2500
