Engineering explained best watch out! Good white board work man!

[@bigbertha441]

Lmfao!!!

[@brocklndrs]

Engineering explained don't do sound effects though, 🤔

[@nerbon7164]

Hughes Performance, Richard Holdener sound effects and Engineering explained all in one!

I was gonna say, does Jason know you coming for this gimick🤣

[@coyotefury]

Just wait until Alex does a white board explanation on clutch slipping

[@Prestiged_peck]

I learned so much more from this than I do from getting yelled at in the streams, thanks for the video Alex! Looking forward to more science of hotrodding videos like this

[@even_i2622]

Thanks for the break down about the why’s and why not’s of torque converters. I hope you keep putting out videos like this one . I feel like I understand torque converters much more then I did before watching this.😊

[@prodbybigl]

See I never understood torque converters but this video helped me gain a better understanding of it. Thank you Alex‼️

[@darrenhart2309]

This was very helpful, i just installed the 3c on a 03 cobra with a gen3r and 6r80 and i noticed the exact same graph in a data log when the converter locked! Awesome info!

[@Christian_sama]

Johnny sins doing side quests in the car genre now. I like it

[@Thickercarton]

I was hesitant to click on your videos just because I thought you were another KZbin “expert” giving dumb advice but you know your stuff and have good explanations and advice. I was wrong therefore I subscribed. Keep up the good videos!

[@guthrie_1]

I love converter lock up. That direct connection feeling is great.

[@GTiGuy316]

I vote for keep these vids up. I learned and enjoyed your explanation.

[@ConnorCG317]

Researching to buy a converter for my Gen2 truck , love that you’re diving into this topic!

The white-board Coyote Crash Course, love it.

[@snaken9561]

Favorite youtuber right here! Alex for the win! Thanks for the info sir

[@TheChevykid93]

Have a way better understanding for converters now. Thank you for this very good video

[@RetroFoxZach]

Reminds me of the hot and crazy woman matrix chart 🤣🤣 Good video though Alex! This is good stuff!

[@monterogers]

Really great noises. I added in my own wheel hop chatter for that authentic feel.

[@blackmotorsmatter7012]

I think I remember you talking about this when you had the red car at the track. You could hear the converter lock and the MPH was faster in the 1/4 then leaving it unlocked. I may be mistaken…either way great video Alex! Love the whiteboard series 😅

[@andyali13]

Damn! Alex pulling out the whiteboard. It’s a great change to your channel Alex.

[@AbduMad]

the noises you make is what made us understand lol

[@zrgray]

I love that we’re getting a converter lockup tutorial on international women’s day. Classic.

[@tuloko16]

Great explanation!! One thing you should had touched on is: When the RPM drops you are “resetting” back to your torque peak, or just below it. I think that point makes people grasp the concept a little easier. That also explains the “why my car got slower with a higher stall converter?”. Many times is because you “flashed” past your engine’s torque peak.

[@adamleighton8052]

This makes a ton of sense. I have 2022 tacoma, 6 speed auto, with a 3.90 rear gear I believe. The converter will lock in 3rd gear. When the converter locks it’s very noticeable. (Thought it was a gear change, after the video realized it just lock up) the trans was the only complaint I have with this vehicle, however after this video I generally have a better understand now what’s happening in the trans and it isn’t as bad as I thought. I thought the gear hunting was bad, however it’s just the converter locking and unlocking, not necessarily gear changes to help aid in lack of LOW end tq with the N/A 3.5 v6

[@petermandics1517]

Expertly done, Alex, and please, more whiteboard/professional soundtrack demos. My experiences with Turbo Buick's (way back when) was exactly the same, especially the stock vs. high-stall converter lockup experience and better performance.

[@jpsantone]

I like these white board videos

[@Swindez95]

Other aspects of torque converters such as torque multiplication and stall speed as it pertains to engine power curve and optimal launch rpm would be good to talk about as well. In a nutshell, torque converters actually multiply the engine output torque on acceleration but once rolling under light load, the turbine and pump start to reach the same rpm, there isn't enough slip in the converter to effectively multiply the engine torque and that's where the lockup clutch comes into play. The lockup clutch turns a fluid coupling into a mechanical coupling reducing heating of the fluid within the converter from constant fluid shear through the turbine and pump.

[@yuma6089]

The whole whiteboard series is a great idea and your visual explanations of what to look for in the dat logs are quite helpful. I have just recently started to data log my gen 1 Mustang GT to try and gain some insight in how the ECM manages things. There is so much to learn and you are helping to put everyone on the fast track. Thanks for your many, many, hours of content.

[@Khalid_Sbawi]

I like this style of videos! Keep it up Alex

[@braggersum]

love these type of breakdowns

[@DivisibleRex]

Good to see a visual of what yall see while tuning. As always best channel for info explained in a way to easily understand.

[@blown0595]

Love the info bicho. Good stuff

[@ridinonchrome1374]

Good video. Thanks. Don't have a higher stall in Mustang but had one in my last car. I was always curios how it was different it was from stock one. I had a issue at issue at first with it where it was locking and un-locking constantly while driving. I had to get a better tune to fix that.

[@twitchfpv6797]

Damn Alex you should do more videos like this. Good shit.👍

[@tannerfaye2285]

I have no idea about how any of this mechanically works. I just understand what it does on a time slip. So this is very very entertaining and informative to watch.

[@Nawsad1]

Class is in session Mr. Flores! Explanation was clear, and well represented visually. Maybe once a month you bring the whiteboard out for more

[@Vaca1950]

This is badass. Believe it or not, I used to always hear this lockup on your red car and always wondered if it was meant to do that. Badass work Tio, love this new style of teaching us kidzz

[@mattoliver7650]

👍👍 Solid. This is solid. I learned something today. Learned about what a "Lock-up" converter is. So helpful. I did find myself curious about the temps and the difference in temps between locked and unlocked. Then again, "Everything gets hotter" doesn't need to be elaborated upon.

[@Shamilt3]

Good explanation Alex, especially for me being a guy with not much auto experience. This is how we would interpret clutching for snowmobiles for racing application.

[@davidgodinez7154]

peasants explained lol

[@showmerepair]

I love data. I wish I could work at Lund. Love the white board videos. These should be you highest viewed videos. But because your not acting like other nut job KZbinrs people don’t like it.

[@camyota]

I would love to see the look on someone's face as they passed by Alex's office as he's going over datalogs. 😂😂😂

[@YDBT4LIFE]

I work from home.

[@slidewayz432]

I love this content 5min in and learning new things! Now I know the diff between a shift and converter locking

[@Rebel635csi]

When i had a 5C in my N/A gen1, i loved the torque lockup, it would literally shove you forward as it dragged the engine down.

[@rsoito74]

Good shit Alex, and keep the sound effects!! Vroom Vrooom..👍💪🤙

👌👌 great explanation.. Would like to see more of this.. come on guys. Lets support 👍

[@akbarroosevelt2246]

This new series is awesome

[@alex_5.sl0]

My F250 locks up after 4rth before the 4/5 shift, just the way Proven tuning has it, maybe its the same in stock configuration and everything you just explained is just that . Couldn’t be anymore clearer, hope this helps others understand that a dip or “bog” is just converter lockup

[@timo1642]

Professor Alex Class is in session 👍

[@LearnSomethingHelpful]

Thank you for sharing

[@nawaf0621]

Thats a good explanation Alex, Thank you. We need some explanation on 10r80.

[@YDBT4LIFE]

I'll work on that with Jr so I can explain it to the poors

[@mjcmustang]

Coupling is correct terminology for "locking" the converter. A torque converter is quite similar to a hydraulic coupler, with some slight differences

[@10r80sergio]

great content as always

[@JustMakinHorsepower]

Good visual tut

[@blown06tc]

Good info. I found it beneficial at the track with a centrifugal to not lock it. Locking it seemed to drag RPM down further where the car wasnt making as much boost and therefore making it harder to pull itself back. I dont have too much inherent slip compared to 3C or 4C, I have a 2c.

[@YDBT4LIFE]

Wrong. Lock it always. locking it and shifting it higher in a Centri application is key

[@blown06tc]

@@YDBT4LIFE about 7700rpm shifts. Locked rpm would drop to 5300 roughly, lucked no lower than 6300. Jr agreed to unlock it to see and car dropped close to 3 tenths and 3mph at pbir. Also 60-130s quicker too

[@YDBT4LIFE]

@@blown06tc must have a tight coupler

[@blown06tc]

@@YDBT4LIFE 245 2C. Jr said unlocked it doesn’t have what he would consider a lot of slip. Based on logs at the top of the RPM is 2-300rpm of slip

[@YDBT4LIFE]

@@blown06tc makes sense that's why I referenced the circle d 3c

[@zekevillarreal2694]

I have a great video of me doing some shenanigans but you can clearly hear the lockup on my converter. I know it doesn’t help anymore with this video being released but I’d love to send it !

[@3turbo144]

My 6R80 Gen 2 behaves kinda like it has a high stall in normal mode under normal acceleration. The converter never grabs and it just sits at a constant rpm but keeps accelerating (kinda like a cvt). It’s shifting through the gears you just don’t hear/feel it. If you accelerate harder or put it in any other drive mode it shifts as normal

[@sabinoguzman7780]

When I saw the link picture I thought it was a other F around and find out video lol 😂

[@halfboltedon9162]

I love this type of video, I have a question. If locking a converter is more beneficial to ET and MPH, wouldn’t it be more beneficial to keep the converter locked all the time from the start to have more torque?

[@anthonygrebner]

Nope. Torque multiplication in the unlocked convertor is a huge advantage on initial acceleration.

[@halfboltedon9162]

@@anthonygrebner thank you for the explanation I appreciate it. I didn’t think about the torque multiplication and how that would be beneficial at the start.

[@brocklndrs]

Back of Alex's head, a rare sight, 🙌🏻 😂

[@robhunter2435]

I put a non lock up convertor in my 86 fox... maybe should have put a locking one in. Not sure if this pertains to plain AOD cars. This does make sense. Thanks

On today’s episode of “the more you know” by Alex

[@notacoyote2790]

What controls lockup in the converter? Is it something mechanical or is it something in the tune? I’m a stick shift person so I know 0 about automatics but just bought a 14 f150 so I want to learn.

Hi Alex, would it be possible to lock it up in 2nd instead or 3rd. If so have you ever tried it. What were the results? 👍

you dont want the converter to lockup at the shift of 3rd correct? you want it to lockup once it been in 3rd for a lil bit right?

On a lower hp application like a fbo gen 2 car. I notice my car lockup on the 3-4 shift. Which on a N/A 15 with 3.15 gears I don’t see all that often when I’m WOT. Is it a disadvantage that I don’t lockup within the quarter mile? Thanks!

Here's a great video where you can see a c7 Corvette shift, lockup (and continue on to get gapped by a 2013 gt500) kzbin.info/www/bejne/bnfLaWp8fKihfZY The 8 speed transmission converter is a terrible design on GM's part. The "5th gear wall/bog" Camaro owners talk about is a real thing.
