Hey I want you guys and girls to know this channel is high quality , the mic quality , the music mastering with your voice is on point , thanks for being so humble and sharing this building tips and tricks !!
Thanks for your feedback and thanks for watching. We appreciate your support 🏁
That's very nice of you to say 🎉.
My builder literally made me buy one and ditch the 'lightweight' crank pulley on my Subie. Heck, it could have been a culprit for all I know. Thanks Jay for another good video to show people real life scenarios and actual facts. This is certainly one part that gets overlooked on many modded cars. keep up the good work on the videos guys!
You never want lighter weight on a crank Pulley
Lol my builder done the opposite and my oil pump exploded
Agreed. I never knew this about the balancer.
Probably one of the the smartest in the business
I'm in the middle of my 2jz build and I was using a cheap "flashy" aluminum pully set. I had no idea how important having an actual damper/balancer is. Thank you!
Kurtis Koepke
change that asap
Literally same here vro luckily i have no ordered yet🙌🏽
Thanks Jay! As usual only the best informative info on part's we see everyday but not really understanding the importance of them until explained in detail! Realstreet's the Real deal.
Just installed mine and I must say what a difference it made. Little to no cabin vibrations now.
Without the vibration damper, the engine experiences torsional vibration - the front of the crankshaft moves back and forth with respect to the flywheel. This can cause a very rough running engine at certain speeds and the back and forth rotational motion of the crank will eventually overload the rod bearings toward the front of the engine ultimately leading to failure.
Also, crankshaft balancing will help with this.
This one video made me subscribe, and I've literally never seen any others. Informative, concise, and it doesn't go traveling off into unrelated territory to beef up the runtime. Great video, I will definitely be back for more.
Thx for your tech tips. Theyre very useful and contains topics which normaly nobody thinks about. After watching this video, a few months earlier, i purchased an ATI for my rb26.
Thanks man, I finally found some no bullshit information on balancers for my build.. Cheers
best channel on RUclips 👍🏻thanks
Exactly what I am going through right now. Bought a 1987 E350 ford. Motorhome and its just fucked everything. Belts burned snapped off, blew transmission line and snapped another belt clean off. Thank God I noticed the rubber dampened sticking out and mentioned it or they wouldn't have fixed it or noticed. 🤦♀️
Music is on point, I learned something on that note lol
Favorite car channel period. Great info from legends in the industry. I’d love to see some N54 content, it’s a very affordable platform for your average joe, that can also make good power
Great vids that I always keep coming back to.
I wish Evan or Jay was on the west coast for sure. These are two tuners that I would love to have at my disposal to tune with.
Jay's Tech Tips back at it again! Super informative and great source of information! You are doing the work that many wont take the time to explain, appreciate it @jay
Been running solid well-balanced aluminum crank pulleys on several different tuner engines over the years and haven't had any of the failures stated.
Checking in 3 years later and yes I still have light aluminum crank pulleys on 9K RPM 600whp 4AGE, 375whp VG30DETT and 300whp J37A1 with no failures or problems.
@@DJToneRI I like you. That's the way to comment. You came back after 3 years and reply to all of us. I hope everybody has that in mind.
@iris baez 🤣 no problem! Just one man's experience but at least that's worth something!
@@DJToneRI Nice man. Good to know. Know anyone running one on a FBO and tuned K20? I should be good since my engine is internally balanced.
This comment 👌 👏
Honda F and H series from Accord and Prelude where 2.2l-2.3l had extra balance shafts in the block that ran along with the crank driven by a timing gear.
I have a Honda crx which came from the factory with no dampening at all just a steel pulley I "upgraded" to an aluminum one and had the machine shop balance it. After watching this it makes me want to put on a heavier stock dampener. Since the alum one weights less than a pound
FiendForLows never use lightweight crank pulleys it leads to bearing failure
Even a new fresh oem style one is a good idea if your on a budget until you can get a good one, if needed for your hp level
It's a misconception it's automatically a balancer. If your engine is internally balanced it's a harmonic damper. If your engine is external balance it's a combination balancer damper.
thanks for your time! great video
Glad you enjoyed it. Thank you for commenting.
Omg thank u sooooo much bro…especially going into details 💯💯
Thanks from England.
I'm planning on having the ATI super damper installed on my 07 Z06 with an 10% under drive. The OEM just doesn't last very long. I'd rather pay 3 or 4 times the price over OEM than to have to deal with it again sooner.
C6Z06 if you take the rack bolt out on e one side and the motor mount on the other and jack the engine a tiny bit to one side you can sneak the crank pulley bolt out no problem
How about having the rotating assembly of the engine balanced? I am a fan of that for helping to reduce engine vibration.
Mr. Adventure haha yea tear it down to bare block might as well rebuild the whole entire engine while your at it.
Damn! I never knew about this car part and this video was incredibly informative! Thank you!!!
Should have added something about underdrive/ overdrive pullies. Alot of people run them that don't even have dampening
I'm running perrin lightweight crank because it really does free up hp and i dont mind rebuilding after 150k to have reliability but thats my opinion
Lightweight pulleys seem to be good idea when you have lightened flywheel and removed a/c and power steering pumps.
But for lightly tuned street engine they may cause more problems than benefits.
I made the mistake of buying and eBay lightened underdrive pulley/dampener for my DSM it completely change the low RPM and start off characteristics of my engine it was like having a lightened flywheel I had to go ATI to get my daily drivability back.
Did you also use a lightweight flywheel? I like the zippy response of a low inertia bottom end, but yes I agree it decreases driveability
I have a lightweight flywheel in my Honda B series build. No power steering, no AC. Should I use a good aluminum crank pulley?
I'm thinking the ATI pulley might be a bit too tight for mine.
1.3820 inches crank snout OD vs 1.3745 ID ATI hub.
I accidentally turned the bolt on the harmonic balancer off of spec trying to replace belt any how I noticed vibration at speed how do I reset it back to spec?
If its bad, does it throw the belt off a bit to shred it on 1 side?
An aftermarket balancer is definitely a must for any engine build
Im glad you popped up everyone else talks to much
I didn’t have a damper on my b series turbo and u guest it 😢
Please don't tell me I need this on my 156K 1999 Ls1 Camaro I get a bad vibration at a low RPM if when in Park, Neutral, or driving at a low RPM like under 2KRPM. Been doing it since 140K miles. Will I ruin the bottom end of the engine or driveshaft? I try to run it at a higher RPM and it goes away.
What is your background music? I want to use it for my podcast
Not looking for a ton of hp or looking to be at high revs all the times so a lil lightweight forged aluminum crank should last a bit ?
Let’s say my car doesn’t have an ati damper application, would a simple $100 aftermarket/replacement harmonic balancer react the same way as the oem?
Thanks buddy,I’m into vw air cooled and the harmonic balancer does not exist from factory so would it pay to put one on thanks 😊
Why does this come up in my recommended one week after my OEM balancer's rubber disintegrated in the middle of a cruise...
How about underdrive pullys and the rumors that engine accessories will suffer? Can they still dampen out engine vibrations as well as factory? thanks
Hi I had 2x crank shafts broke of behind nr
4 big bearing can that be the reason for not use a damper
Hi, I have a question, so I am looking into getting a lighweight crank pulley for my car but as you've said it can't absorb the vibrations at high rpms. But my car only produces 90hp stock from the factory and the rpm redline starts at 6.5k rpms. And Im mostly just daily driving at decent speeds at around 3.5k-4k rpms. So is there alot of vibrations in those kind of rpms in the first place?
ATI has pretty crazy instructions. Kind of covers everything and not just what you bought. Confusing. This video make me think their instructions about honing the ID of the hub for the interference fit might be not what I need to do. Steel hub on LSA crankshaft. Hub is about .002" undersized. Thinking heat in boiling water might work best.
I bought a fluidampr instead of an ati super damper both are Well worth iT
I have fluid as well, i've got my fingers crossed. I might pull it off after 30,000 and see what state it's in. Though my timing marks were incorrect on mine. What about yours?
@@Skirk84 mines were fine, check your TCT & chain.
@@PatrickMeloModesto I just built the engine. Base Timing is set correctly, but the marks were just off.
Team Spintop weird man. Does the car run fine otherwise ?
@@PatrickMeloModesto yep its good, makes good power, doesnt ping, spools super quick. Just the timing marks. You set it to tdc and its out by 10 so highlight the new mark for tdc, degree the cams, set the base timing, check it with the gun and its exactly what you set it to in the ecu. Just out by 10 originally
Thanks for sharing
Elastomer vs Fluid?
i kinda want a ATI damper for my na 2jz 🙄
buy one...?
There is an alternative to Fluidampner or ATI, dayco powerbond.
What about a video on how to ensure TDC on a 2jz when the engine is sealed ( i.e. Head and oil pan on )
Hi, iv been looking at your real street dampener and fluid dmaper. The only reason I look at fluid damper is its self tuning. The Ebay real street model does not say the Durometer specs. Also videos say you need to tune the ATI. Is their a safe window for a 2jz-na with bolt on's that Rarely sprays nitrous, that i can buy and bolt on without tuning? Thank you.
Will a lightweight flywheel needs a different tuned harmonic balancer?
What brand are good harmonic balancer s?
What about honda engines? are they just pulleys or "harmonic" balancers?
hey guys ,so a bad harmonic damber can affect the power and rpm of my car ? i have a sportage 1996 gasoline with harmonic damper just cracked :(....
I can't find a balancer for my mazdaspeed 6 the balancer is toothed for the crank position sensor maybe that's why they are rare
Hello which brand is better under drive pulley. One by summit or jet performance. I have a 2014 Chevy Silverado 1500 5.3 z71 LT. Suggestions plz
Hello can you my question please
*has some of the best advice on youtube* -
*only has 91k subscribers*
Come on guys, stop sleeping on real street
Can a bad SFI harmonic balancer that's gone bad ....keep eatting the front seal out of my 302/347?? I keep having to replace them ...and when pulled out they look like a dog chewed them up ...also it's a Supercharged build ??? please help ....
I'm doing a diesel engine swap. It's an older Cummins A series inline six. Made before the famous B and BT series. This engine is the outside size of a 300 CI Ford inline six or a GM , JEEP inline six. I'm having to fabricate everything about this swap including Flywheel and Bell housing. I gotta get with Cummins and see if they can recommend a balancer for the front because it only now has a direct drive V pulley. I have a couple inches between the flywheel and the back of the block. Would it be a good idea to mount a harmonic balancer on the flywheel itself to help the whole engine be smooth? This engine has a cast iron crankshaft which I thought was odd. I sure don't wanna break the crankshaft as I've seen done before when using cast iron crankshafts. I'm wishing to use Teflon around the flywheel bolts to take out part of the jarring when the clutch is engaged. Would this be possible to take the shock out of engagement of the clutch?
I change to Work Engineer lightweight pulley on my K car, which they claim to have pro balance technology. I am not sure how safe is it, still monitoring after a year plus.
Can anyone tell me which brands and/or sizes will fit my 87 mazda 323??? Please???
How can you boil water to twice it's boiling point? I know it's not important to the video but it made me rewind and wonder "wtf" lol
Bone-Harmonic thug balancers in harmony:)
Lol😂
literally laughed out loud when i read this.. brilliant! :)
i had my chevy 383 stroker internally balanced. i am running the 400 balancer on it now. but im about to change it to a 6'' street balancer. is it going to throw off my internal balance ? and cant i just change out the short timing marker for the longer one to keep the correct timing setting ?
Dp you suggest the Dorman replacement for the jz motors?
I would love to work at Real St. and meet Jay
Can I run this on a rotary?!
Good Demonstration
What about light weight under drive pulleys???
what about light weight aftermarket harmonic balancer on a built 200 HP na civic d16 engine
My evo 8 got balance shaft deleted now I getting buzzes at certain RPM would this pulley help?
Thanks
Hi, I just installed an ATI Super Damper with 2% overdrive and lightweight hardware on my MINI R53 and I’m hearing like a wiring sound, almost like if there’s a strong airflow going through the pulley, is this normal or could have possibly installed it incorrectly like maybe too close the the wall and it’s scraping? Thanks!
Hi Jay 🙋🏽♂️
Just i would like to know your experienced idea about 2jz wobbly timing belt between intake cam shaft pulley and crank pulley while engine revving around 3,000 rpm...
Thanks for experienced ideas 💡
Regards
Do you need to boil if you use the installation tool?
So I read some replies and still don't know. Not sure of the difference on balancers and dampeners. Still go in the same spot right? Front of the engine? My engine (350 Chevy) vibrates a lot at higher rpms. I was told it could be the flywheel or clutch plate...then yesterday a transmission guy says it's rare and he's never seen that before. Says its gotta be the balancer.....???
Beetlejuice117Kc dont quote me hut i believe they are the same thing called dofferent things by dofferent people
The hub is only a balancer... ? this is nothing about the oiling system at the base ?
Thanks does that mean we need to balance the crank and balancer together to find the correct harmonics
good video Jay
Too dampen is to make wet, to damp, is to mitigate vibration .
How do I know if it's the Harmonic Balancer and not The Crank Shaft ???
You mean, how do you know if your crankshaft is bent or broken?
Yes...
Or if it is simply my harmonic balancer
Ross gold balancer or ATI and why?
how'd you get the instrumental for this track? would really appreciate it.
I have an under drive pulley kit on my K series.. Does the ATI pulley replace that or run off a separate pulley.. Thanks
Jose Melendez Jose, the ATI balancer replaces the pulley you have now and will drive your belt once installed.
thanks.
What's your thoughts on Fluiddampr ?
I replace my Harmonic balancer for an aftermarket thinking the vibration will disappear, but nothing happened, so the aftermarket doesn't do shit.
for the 2jz setup, which one is better, the fluidampr 840801 or the ATI super damper
I'd also like to know as i'm running the fluid, but have always known ATI is the business.
I went with the fluidampr because it utilizes the factory sized serpentine belt i.e. the pulley is the same diameter as the OEM pulley. I hear ATI requires a different belt size.
This is an old video so hopefully you can answer my question, but is a fluid damper needed if you're running a stock engine with an aftermarket light weight flywheel since it's a recipricating part of the engine? Reason is I recently installed an ACT light weight flywheel on my s2000 ap1.
And this is a old answer : yeah
Thank you....good info.
If you get these random vibrations during idle, could it be harmonic balancer? Changed to solid mounts 3 yrs ago and have this vibration during idle. Almost seems like care is about to stall out sometimes.
+JOe Shmoe Are you certain the engine is not misfiring? Solid mounts will definitely transmit more vibration into the chassis but won't cause the engine to stall/shake a lot at low speed. Without being there to see your car it's hard to say if your vibration is "normal" for solid mounts but the stalling condition is not related to the balancer.
thanks
What about internally balanced engines with balance shafts?
Regardless of the balance method internally all of the points are the same.
@@stevenp3176 not true. New model 4 cyl Honda’s don’t even have a “harmonic balancer”. This is V8/6 issue.
Im slgoona send it with aluminum one
Quick question! On my B18C I want to run the alternator only * no power steering or a/c *, but I want it to still charge my alternator for accessories like headlights. I have heard the *RACE* Damper will not charge well on a bseries. Is there any way to use the Race version on the street or buy a super damper without the extra a/c and p/s pulleys?
Yea
Can i get one for my chev 350 to add power?
Good info, thanks man
Is there any way to "build" your own pulley? There's a company called that makes a prebuilt ATI pulley for my motor, but it's $800.
No, they are tuned specifically to negate the harmonics produced by that particular engine through a tuned section of the rev range. Building your own would be worse than not running one at all.
Where can I get one like that for my car.
