The Fast Lane with Stevie Fast: Unlocking the Secrets of the Lock Up Torque Converter

For the first time publicly Stevie breaks down the lock up torque converter from the worlds fastest NHRA Pro-Mod legal nitrous run in history (Bahrain 1 Racing’s Barker Max’s Cameo named “Moby Dick”). In this video Stevie tears down inspects, how to set, explains the do’s and do nots and assembly of his Neal chance lockup torque converter.

I firmly believe that one reason Stevie is such a successful racer is that he obviously understands the equipment he runs. Love this tech stuff. Keep it up from time to time. Thanks 😊

The guy is dead on! When you wanna set world records this is how dead on you gotta be. I can’t tell you how much I love watching these vids. Keep up the work KTR!

[@SModelMafia]

This vid popped up after something else I was watching. I doubt I will EVER have a converter like this, but I watched til the end. You are a good dude Stevie.

[@roddogg914]

Awesome video SF. Racing fans who are not subscribed to your channel, don't know what they're missing.

[@janetlidvall3777]

Stevie you are a steely eyed missileman. Pro Mod is the future of NHRA. By far the most entertaining.

[@souqmadiq4835]

This longer style of informational videos are awesome I could watch them all day

[@reallybadaim118]

I've learned more here in 36 minutes than I thought possible. Thanks for the video.

[@cpbarnes24]

Best video I have seen to date on a lock up.

[@CentralVAracer]

Best converter video I’ve seen. A+

[@WilliamCShinn-zl9ll]

This is valuable info for all walks of life, thanks a million Stevie look forward to alot more video's. You can never have enough info. God Speed brother

[@cpolt1192]

Thanks Stevie! Was out with a Cust and we wanted to change stator, but hadn't done one like this before.......then I rem, you made this video! Thanks brother! KTR FTW!💪

[@prestonedmonds4128]

Thanks Stevie. Now I understand how lockup works.

[@dardenboyzracing5526]

Baddest man on the planet! Thank you for everything 🐐

[@sanger440]

Outstanding content and humor. Thank you for that.

[@alfonsominopoli9301]

Great job Stevie! I watched this video before and I just watched it again. I think you do an amazing job sharing what you do with us. I’m looking at getting a Chance billet bolt together converter soon and you definitely gave me a comfort level that makes me feel like I could manage adjustments on it without too much difficulty. Thank you!

[@mikebonge7206]

That was best video I have seen. Thank you. It is a really first class piece of equipment

[@mannieecker8602]

BadAss peek into the workings of a modern day race car.......Thanks for this Stevie, I appreciate your time and effort!

[@Spad68]

Great video during these crazy covid19 times . Liveit . .keep them coming .

[@mattunes5823]

This was awesome. Thanks for the information. I'm cringing thinking about someone jamming those bolts on with an impact without starting them by hand.

[@dmeemd7787]

Oh God, me too! As I was watching this (I can just imagine walking from a pit I'm working in or just hanging out and walking over to another pit) and watching someone load one of those bolts into their impact like they are putting up drywall, lol, and immediately hearing the impact beat the sh*t out of the bolt...followed by 2 more scenarios in my head 1) the person quickly stopping and realizing they might be able to salvage it with a tap but still sh*tting themselves because they won't be working on the car anymore or 2), they don't let off the trigger until the impact stop hammering because there's no aluminum threads left or no head of a bolt left.. LOL.. and my guess on that is oh, they make that kind of mistake, then god only knows what else they've done to that car (which is SKETCHY) haha Speaking of, anytime teams are just straight-up shorthanded and/or have volunteers that aren't too experienced, the anxiety level definitely for me being on a crew or watching a team (especially when they are shaking down a new.car, etc..especially high-power stuff, people aren't looking at stuff such as header bolts, body fasteners and so on, just to name a couple examples, things that you do not want falling off the car and going under the tire or on to the track for somebody else to run over and so on. Something I've seen with a few different promod is they may only be running a high seven or eight second quarter mile because they literally are making their first hits and slipping the crap out of the clutch or converter, usually intentionally and anytime you're potentially adding a few SECONDS of ET, the guys GOTTA check everything, especially once they're at the shop - otherwise you don't know how often things will rattle apart oh, what kind of service live your particular car might have and so on...AAAANND I'm going to stop here because I didn't mean to derail THIS much LMFAO 🤷🏻‍♂️😂

[@dmeemd7787]

I've heard people and do dome of the DUMBEST stuff when it came to converters, and everything I could remember them saying, never sounded right and you just made fun of 80% of them LOL - makes me feel a little better 😂 - awesome video and thank you for the time to do this!

[@oikkuoek]

Very nice video! Thanks! Btw, if your O-ring doesn't stay in place, that means your install grease isn't thick enough.

[@That_Corvette_Guy]

We definitely need more videos like this!

[@hotrodriguez549]

Keep up the great vids Stevie Fast. Thank you big time this is the best description on tear down of these I've seen. Baddest man on the planet.

[@wymple09]

Mechanic at the top of his game. Now how about some kudos to the scientists & engineers who design & build this stuff? Highly technical world we live in.

[@johnbowen2963]

Dam good video, very well to the point. , do drama no music , just good info, GOOD ON SFJ!!!!!!!!!!!

[@TopNotch50]

Would have loved to see you send that piston flying after dropping the hammer on the airgun. Lol Great video.

[@young11984]

So glad to see somebody else not treating parts like egg shells, good vid with comedy added

[@projectleftoversracing-mat234]

You guys are killing it. Keep up the good work on and off the track

[@TCDallas]

Excellent! Learned new stuff! Thanks Steve!!

[@Cise82]

I absolutely love in depth technical content like this. I would love to see more content like this! Keep up the great work and keep grinding and making shit happen. KTR TTFMFRS

[@dennishensley1150]

He'll yeah, Grovetown Groovy , very thorough and detailed . If and when we meet at TRACK I might have to beat you on tree (light) . Build then, race them,and service them ! You're Good,Real GOOD !!!

[@ryansaiki6768]

I’m ready to tear into a lock up converter after this! Great video! We need more in depth videos like this! Maybe one on a screw blower vs roots and one on the trans?

[@jrsgarage3244]

Wow Stevenson what a super great teacher you are very impressive details !!!!🌝⚡🏆🏅

[@hoost3056]

Never forgot him explaining the tune on his blower car....Donkey, drop, Bermuda Triangle, Promise Land. Fuel is squishy ( or something like that ), ignition gives a harder change. I think I got enough to tune a Pro Mod!😝

[@toddberry1617]

BFH is a Matco part number glad you remember

[@jeremyeubanks2387]

That was a great instructional...thanks for your time

[@charlesrives9092]

Great technical content. I would love to see more about the servicing you guys do- especially the blower.

[@cooltrkin]

Love it, I might need to buy one of those transmissions.

[@scottrussell2281]

I hope Marty helps your program out for doing this. You are extremely good at instructional videos.

[@neilrobertson1345]

Excellent video Steve

[@mann5353]

Another great video Steve...

[@jeffbrooks6166]

KTR converter school now in session! Great video Stevie thanks

[@myefhatch]

Great video! I actually learned something from a KZbin video!! I've always been a stick shift guy so it was cool to learn more about an automatic. 🙌🏻🙌🏻🙌🏻 Thanks for making this video 👍🏻

[@bobbysears6626]

Great video Stevie!! Keep up the good work on and off the track! Stay safe!!

[@micahbuchheit1283]

Been needing some KTR !! THANKS FOR THE CONTENT !!!

[@rafatrill]

That's crazy I've never seen that before very interesting pretty much the same as a transmission

[@crazyoilfieldmechanic3195]

Man what a loooooong dry spell since the last tech vid and when is a Q and A vid ever gonna happen again ? Really enjoyed the info about that type of converter. How much do they cost and how much do T/C drives for the trans cost ? You need to do another ping pong ball drawing for fans that lets them help with the car in the shop. I'm not gonna anything about the clutch disc left on the table or anything about turbans (since you have been to Bahrain so many times) or ask you where your mask is or remind you to stop touching your face lol Needed to see some Stevie Fast .......thanks for making the effort and keep yall safe there now.

[@ira_peavy]

Best video yet! Thanks for the tutorial Stevie

[@G55STEYR]

Most beautiful thing in cars!

[@RaceProvenMotorsports]

Redoing a converter with a 12K dollar watch on.... I like it haha

[@ryanveret4088]

Thanks A Lot Stevie!!!! Always appreciate your videos!! 🤘💪

[@davidmcnerney3048]

Didn't realize those things had a whole stack of frictions n steels.That is a thing of cnc beauty

[@monzahunter]

I love the leftover clutch laying on the table after assembly is done. lol Great video, I never knew much about those things.

[@pistoninthewind]

Keep them coming!! Thank you.

[@mikeschwindt7407]

That was a great converter video. Thank you Stevie

[@andyb9767]

Very well done!!!

[@bennyboom63]

Great video Mr Fast. I do wish you were able to build a car that was more geared to us normal blue collar guys who can just build what we can afford. I think we would learn stuff we could put into action more. Thanks for shari g brotha.

[@AndyB718]

Good stuff and thanks for the knowledge.

[@fordsfarms1297]

Thanks for doing this! Great information! That answers every question I had on how you all use a lockup converter. Love seeing the shop stuff and thanks for taking time to put this together. Do yall typically use only Brad Anderson motor parts?

[@2sheamotorsports199]

What an awesome video. Great job. Excellent detail.

[@Bumpy400]

Great Stuff!!! Never could quite understand how it works. Thank You

[@mrproparts]

Very informative, now that you’ve got nothing to do for a while, why not completely rebuild a car & show us every detail of everything ? Stevie Fasts racing tech channel!

[@joshshumway1971]

Do those utilize some sort of big dawg sprag or is that a mechanical diode? Or are those the same thing? Thanks for the videos, always entertaining and informative.

[@russrisley3882]

Fucking KILLER video, Stevie. Was very informative on torque converter maintenance and stater change. KTR for the win!

[@keithmott6428]

Thanks for the video very informative. Keep it coming. Hope to get back to normal life soon. Need to smell some smoke.

[@kevinscott5515]

Finally I can get a good understanding

[@TenSec86]

awesome video, thanks for doing this Stevie!

[@RussellMotorsports]

This was gold... do you guys ever experiment with different clutch stacks as opposed to always clutch steel clutch steel config?

[@keithfrisell4271]

Awesome video! Very informative! Have a great day .

[@hotrodrigs1]

Stevie,Do Not Stare at my O Ring 👍

[@movingup41]

Nice job Stevie Great tutorial.

[@marcophilhom6844]

Two dowel pins in your work bench say 12 and 6 o'clock. dowel pins line up with the holes where the flex plate is bolted. this will hold the convertor in place while you torque all those bolts.can you drive the dowel pins on the convertor through the bottom

[@markdudar6632]

Good content Steve

[@rebelboi111]

Best video yet.... love the in depth technical videos KTRTTF

[@sdelony]

Great video learned a lot

[@blown5.062]

What a difference a good billet converter makes, and they should for that kind of $$ putting out for it

[@gonmad7073]

Just curious... why was what looked like a clutch disc left laying on the table at the end of the build? Great VID!

[@ojscustoms9251]

It was there in the beginning of the video.

[@superjdog100]

Great video love the info

[@ericwilson3684]

Nice, thank you Stevie!

[@kellybrown1860]

Great video

[@patbarrett9263]

Are the "steels" coated or sandblasted? Also, where are the levers to add counterweight? Oops, wrong package. I'm used to the other type of drive mechanism.

[@kennethatchley3355]

Very good instructional video and like the tech tips 👍👍👍👍

[@mutants98]

I see you use trans fluid. Why do I see some with hyd fluid and some with trans fluid. pros and cons to each please. Thanks for the videos. learn something everytime.

[@bcarpenter72]

Craig Phillips the different viscosity of the fluid affects the stall speed. It is a way to adjust without having the correct parts or used in a converter that cannot be taken apart. Sort of a poor mans solution.

[@fascistpedant758]

You may be seeing the same fluid without the red dye.

[@christophercrafts8283]

We've been messing w/ different blade counts n pitch angles trying to dial in our toy 😬 trying to be 1st diesel in the 3s 🤞😎

[@f5garage401]

More stuff like this please

[@krazziee2000]

cool video, thanks

[@chrisjohnson6554]

Cool explanation of the converter , what shop towel/paper do you use to stop the fiber transfer into the converter ?

[@hidog420]

Had no idea that lock up torque converter's were this cool. Stevie know's his stuff, I'm sure that has nothing to do with his success?

[@brentwilliams947]

Stevie Fast #1!!

[@genemounce8302]

Tell Bill Stocklin I said howdy. .......I used to drive for him.

[@CoreyJMunze]

Kickass video. Thank you!

[@misterbutterfinger]

Great video Stevie! Was surprised that you guys use a sprag in the convertor, especially with the amount of power you guys make. Any advantage to using it versus the convertor being spragless? I've heard spragless is good for 1/8mi racing and a sprag is good for 1/4mi racing, any truth to that?

[@curtpratt7566]

I just watched your tutorial in the Shadow and there is was sitting on the bench behind you ..... your salad bowl ...lol

[@SampurpSCR]

Good stuff

[@lenpolidori3568]

Shit! I looked at the o ring. Have to start over now!

[@DSRE535]

This is what gets you subs, awesome video!

[@proline440]

Q&A for you .. The keyboard worriers wanna know why u don't run a Mike Janis Hat/ blower set up?.....I'm a fan of a Pro Mod group on Facebook an we all wanna know what your idea is on that set up lol.... Thanks Kelly from Toledo Ohio!

[@pmreng]

Awesome content, thank you!

[@thedrocca]

Damn. That makes it look easy!

[@yinzer_412_]

The fluid looks good. What transmission fluid do you use?
