Heeltoe's Take On Alloy Crank Pulleys for Honda/Acura Engines

[@ayowser01]

Adding lightweight/under drive pulleys really added response to the engine. It's noticeably quicker to acceletate, especially when rev-match/heel-toe shifting.

[@jimhiscott2918]

And your probably still running the stock flywheel right. Dont use an aluminum pulley. It will eventually destroy your oil pump and crank bearings!

[@HondaAccordPerformance]

I used a lightweight underdrive pulley on my 3000gt for 10 years zero issues. I’ve used an underdrive pulley on my Trailblazer ss for 30k miles zero issues.

[@jimhiscott2918]

@@HondaAccordPerformance Excellent. We were discussing Honda engines. Mainly the b series where the crankshaft runs through the oil pump.

[@HondaAccordPerformance]

@@jimhiscott2918 The only issues with lightweight pullies I’ve seen on 3000gts are twin turbos making north of 500awhp at that point you wanna keep the stock heavy balancer because with a lightweight pulley it can cause the crank to flex, weaken and snap with higher horsepower applications.

[@نايف-ع3ن7ك]

If you have manual transmission you should try lightweight flywheel it will change the car 😂😂

[@jamesj.litteriojr.433]

Very well explained!!!!! My lightweight crank pulley made a definite difference with no issues and I redline it multiple times a night since I only drive it once or twice a week. "A Redline A Day Keeps The Carbon Away And The Mechanic At Bay" :)

[@danielcalquinhas447]

The CTR N1 Pulley is a perfect example. If Honda can run a B16b at 9500rpm for 24 Hours straight you guys really think its not safe for your commute to the grocery store? Common guys LOL

[@Heeltoe.]

Bravo

[@coachgomes]

So, I've read and heard that a light weight pulley gives the motor 5 to 6 more horse power....? Your video was very good, and very technical. Thank you for such details and information. So, theoretically the motor will not have to work as hard, do you think there will be a slight improvement in gasoline milage... ??

[@Heeltoe.]

Technically there could be but honestly I would not upgrade with the expectation of mileage increase.

[@michaeljonathan6886]

So far I've been afraid to rev until redline, but after I watched this, I was brave enough to rev until redline

[@Heeltoe.]

There would be no point to a performance part that would not permit you to rev it out to a safe rev limit.

[@jerzeyonlyone]

And this is why I buy with confidence with heeltoe 👌🏽

[@Heeltoe.]

Thanks so much! #HTinyourcorner

[@assassin_asa]

Harmonic damper/balancer I do believe we mechanics just call it a harmonic balancer because its a combo and it flows off the tongue a little better. Its universally agreed that its 'the thing at the end of the crank that drives the serpentine belt'

[@assassin_asa]

Also, working for an engine manufacturer, the names are all used interchangeably

[@Heeltoe.]

[@sethallison5682]

Didn’t Honda even sell an oem optional lightweight crank pulley for the original CTR with the b16b? If these were so bad I doubt Honda would sell them from their parts department.

[@Heeltoe.]

Yes they did as a matter of fact, the N1 CTR pulley. We actually just got a shipment of five from Japan right now :)

[@David-nb2bc]

I do endurance racing and would the light weight pulley affect the reliability of the K24 engine that are redline for 8 hours a day for an race weekend of about 25 hours total? I already have a lightweight steel flywheel.

[@Heeltoe.]

Without testing it is hard to say for certain. My opinion is, if it is a standard tolerance engine, something off the Honda factory line, it would be fine. If the engine is highly tuned, blueprinted, boosted or otherwise a critical build I would more likely recommend a Fluidampr or ATI unit, which we sell at Heeltoe.

[@chasemcclary8861]

for the crank pully isn't it bad to not have a vibration dampener?

[@lrod312]

Most Honda/Acura engines, especially B, K and J series engines are balanced internally, and NOT via the crank pulley. Most '80s V8 and V6 engines are by and large balanced externally though, which is where I think a lot of the confusion comes from.

[@Heeltoe.]

It's amazing how lost people are on this topic. Even really smart people just spread misinformation.

[@mayjahjay2297]

would this be the same as changing out to a lighter flywheel ? would a lighter flywheel be required at the same time. ive heard reports saying a lighter flywheels puts the car in limp, will the lighter pulley do the same as well ?

[@Heeltoe.]

Performance-wise yes the impact is the same. Lighter mass on the crank means faster revving and better acceleration. And sometimes yes people will say that the light flywheel is somehow not good for the engine. The "limp" mode is not a real thing, not in the Honda range. Some Hondas and Acuras with a lighter flywheel will get a check-engine light (not the same thing as "limp mode"). This is because the system in these cars that monitors engine misfires will detect minimal changes in the crankshaft speed that makes the system think the engine is misfiring. There isn't any performance impact to this light, but it is something annoying and you want if off. Many people use engine tuners to disable misfire detection to resolve it.

[@snowleopard4689]

@HeeltoeAuto At 4:15, on the lightweight pulley there are 4 distinct 'marks' along the outside diameter. Are those timing marks that are also present on the factory pulley in the same location relative to the hub key?

[@Heeltoe.]

Yes those are timing marks.

[@Heeltoe.]

We aren't familiar enough with that engine to say for sure.

[@hydrocarbon82]

I'll try with a nicer comment so this doesn't disappear too: you don't know what you're talking about here. If you do an actual simulation of forces, you find out an inline-4 has fairly nasty 2nd order harmonics. It's a up-down rocking of the crankshaft ends. On a B/D/H engine with an oil pump gear riding on the crank, this can be DEADLY. Coyote V8's offer great examples of similar 2nd order harmonics shattering crank-driven pumps when they are under-dampened (particularly with a supercharger reducing it's damping power). K-series use chain-driven pumps so it's less of an issue. It still imparts much heavier loads on the outer-most main bearings with an undampened pulley. Also accessories like AC & PS add to the dampening effect, so motor with them deleted need even more dampening. Same for engines with lower rod-stroke ratios or higher redlines - they need more.

[@Heeltoe.]

Given that the majority of engines we deal with are K and J and they all have the extra accessories you are talking about, you are supporting the point of the video. But in reality, the people this video is intended for are the vast majority of street-driven engines without power adders and not having the abuse of a racecar. Myself included, ZERO people in DECADES have mentioned to me once any issues whatsoever using a lightweight pulley. Model it all you want, the reality is, telling the world doomsday stories of grenading engines is largely a lie.

It's a total myth, right? Do you do any oil tests?

[@danielcalquinhas447]

@@Heeltoe. This myth was originally spread because American cars from the 1950s-1970s were externally balanced with the crank pulley as a damper. When racers would replace that pulley to something lighter the motors would shake apart. This is not the case with Honda motors because they are internally balanced, I dont see why this is so difficult for the internet to understand.

[@Heeltoe.]

@@danielcalquinhas447 likewise, the secondary reasoning for not changing this part is the risk of stress fractures due to repeated flexing of the crankshaft under powerstrokes. Weaker crankshafts will fatigue and fail if the harmonic vibration from this oscillation isn't dampened. Honda makes no such flexy crankshafts. The only reason to run a racing damper on a Honda engine is under very high load high stress conditions.

[@jimhiscott2918]

@Flash Jones The rubber in oem crank pulleys and in very expensive after market race pulleys is there to absorb harmonic vibrations. With no rubber there is nothing to take up these vibrations except for your oil pump and the crank bearings closest to the pulley. Look on any serious race engine builders motor and you will 100% of the time find a rubber dampened pulley. Especially with us B series Honda engine builders where the crank runs through the oil pump it is imperative to run a very well dampened pulley! I just spent $6000 building another 650hp boosted B series long block and forked out another $365 for a race dampened crank pulley with a smile because i know what will happen if I don't! Again, avoid non dampened or any plane aluminum pulleys!

[@jimhiscott2918]

@Flash Jones Got to love that vtec👍. Look at the Honda OEM TypeR N1 pulley/damper. It is a single belt pulley that is "underdriven" and its ⅓ the weight of a standard oem pulley. I have ran this pulley with great success on many B series. Honda oem Pn#13811-PCT-000 This is a very nice pulley I think you may be interested in.

[@nobodynoone2500]

This 100%, ALL HONDAS COME STOCK WITH HARMONIC DAMPERS. They are internally balanced, but that is not the same.

[@johnr154]

Goes well with turbo?

[@Heeltoe.]

In general I would say yes. HOWEVER, as boost pressure rises and toque increases the issue of crankshaft deflection becomes greater and greater. Especially if the engine is built up with stronger pistons, sleeves, rods, etc you will want to consider an upgraded damper like a ATi or Fluidampr unit to dampen those forces. On a factory-turbocharged car with a stock bottom end (most cases) or a mild turbo on a mild build...I say go for an alloy pulley. It will help you generate more power off-boost to help RPMs come up and get exhaust flowing.

[@vdubsterw2516]

Lightweight crank pullies are nothing but useless junk on my 1.8t vw mk4. I tried 2 different ones, underdriven and not. All they did was make the motor more snappy and rev faster with the clutch pushed in. I even had the car dynoed and it showed a 3 horsepower gain which almost made me a believer. The issue with these is that on a dyno there is no real world load on the car while its accelerating. No wind resistance, no traction and tire resistance on the road. No weight distribution or accelerating under weight. All these load resistive factors working against the car while its trying to accelerate cause the crank shaft harmonic vibrations to be amplified way more then on a dyno. These load factors and harmonic imbalances will cause the engine to lose over all power output at high rpms. You might gain a little quicker torque response but the over all horsepower will suffer. And the best way to figure that out is to use draggy. And do test runs with a light weight pulley in 4th gear to redline and then do the same thing with a balanced pulley. You will see the results for sure. I lost 5 tenths of a second on multiple 60 to 120 pulls with a light weight crank pulley. And that was consistantly done with 6 different runs on the same stretch of highway. Light weight crank pullies look good on the dyno. But in a real world scenario they actually lose over all power. They actually rob horsepower. And i can verify that. And the 1.8t crankshaft is just as balanced as a honda cranshaft by the way.

[@Heeltoe.]

Thanks for contributing your experience! Careful not to mix terms between harmonic vibrations and balancing. They're two different things.

[@vdubsterw2516]

@Heeltoe. yes you are correct. There is a difference. The 1.8t balancer i am referring to is a vibration dampner not a harmonic balancer.

[@cvpifanatic]

I wonder if they have one for a R18 engine

[@Spacedout209]

High performance academy has a video you should watch on the subject my friend 😂😂😂🤦‍♂️

[@Heeltoe.]

I'll take a watch but don't expect it to change my mind. In 15+ years, nobody has yet. Have yet to see practical real world evidence that a modern Honda engine *needs* any kind of harmonic damper, short of a high horsepower race engine.

[@Spacedout209]

@@Heeltoe. that's true your over engineered very reliable low hp honda engine may be fine but that's not the case with all 4 cylinders depending on bore stroke overall smaller piston less torsional push and pull on the crank ie less need for a damper but like my 2.4 nissan motor it's at about the end of the spectrum for a for displacement to still be able to rev past 7k that's not to say that a damper wouldnt help your honda last 20% longer by dampening those vibrations that are just vibrating the main bearings the oil pump the rod bearings the snout 9f the crank, even vibrations being transferred to the valves from the timing chain if u have one and u wouldnt be able to notice a problem until years and years later after it's way too late u cant feel torsional vibration at all it's a harmonic frequency that happens at different points in the rev range that the damper dials out not an actual vibration u can feel or hear

[@Heeltoe.]

@@Spacedout209 Thanks I appreciate the feedback. We just don't put stock in the idea that the stock pulley on your general Honda engine is even a harmonic damper to begin with. It's all in the video. *shrug* I am not commenting on any non-Honda engines.

[@Spacedout209]

@@Heeltoe. I seen that engine with an oem pully on the crank, i think even some porches dont come with them stock but whatever I can do to keep my nissan 4 cylinder from vibrating itself to death all I was saying is I'm sure adding one to an engine that didnt come with one would make it last a little longer even if it isnt necessary

[@austin_94gt18]

I wonder if this is still safe for high to mid range hp built cars (250hp+ cars putting alot of pressure on those lightweight pulleys)😕

[@Heeltoe.]

HP does not put pressure on the pulley...your statement really doesn't make a lot of sense. We sell these for 200-300 hp cars all the time.

[@moustachio334]

Just use a fluid damper for the crank pulley. Makes hp and is still lighter than stock but absorbs any vibrations and if you assume Honda engines don’t vibrate at all because they have magical crankshafts and can ignore the fact that they’re 4 cylinders then I’m inclined to believe you’re selling these pullies or making commission from sales. I wouldn’t trust those shitty looking garage made pullies either. There are far superior brands that make lightweight pullies. How much money do you make selling these pullies versus the cost to make them? They look like some Alibaba junk.

[@Heeltoe.]

Well a lot of hate in there. LOL, I'll tell you what you lost me at a fluid-filled damper makes power. Sounds to me like you're more interested in saying a bunch of negative things than actual facts. Every one of the pulleys in this videos is a quality made part and with the exception of one they're all made in the USA.

[@matthewscarpetta]

is an aluminum pulley safe for a SOHC D16A6 with a mild build? i'm reading that it can make your engine vibrate to death!

[@juansolo1617]

Why not just have the lightweight pulley balanced?

[@Heeltoe.]

These parts are made concentrically. They are basically balanced off the lathe. But that is not the concern people have anyway. They are worried about damping destructive harmonics, which is a non-issue.

[@nicselectronics81]

Can't wait to put my OBX set on my K24

This does help with that initial resonse! Unfortunately it's just a little more pep, not a huge difference.

I was thinking of onorthodox pulley ..hopefully i see before after video

[@KeepinItReal890]

run a 9lb flywheel and buy an ATI damper. don't be cheap on your $5000 fully built motor. all the responsiveness you need.

[@Heeltoe.]

Nobody said this advice would be taken on a $5000 fully built engine. This is general advice for the average street tuner.

[@ACamps53]

Great video! I have one question: Do you think that between all k20 specs, the crankshaft pulley are the same? Im asking because I have bone stock 8th gen civic si (k20z3) and the crankshaft pulley is wobbling, so looking for the part the exact replacement is 160$ while ive seen other crankshaft pulleys for other k20's for 40$

[@Heeltoe.]

Yes we think pretty much all the K20 pulleys are interchangable.

[@ACamps53]

Might be too late, they are interchangeable but the diameters are different.

Hondas all come with harmonic dampeners. (even if they are cheal rubber style ones) Not running one will kill your oil puimp. Stop spreading misinfo.

@@04tacomaguy1 as long as the crank is balanced these parts do not cause any of those issues on the Honda engines were talking about here.

[@04tacomaguy1]

@@Heeltoe. it's balanced for the heavier OEM one when you take one that only weighs a few ounces on a stock internal motor it will cause issues down the line. Now if you have different crank rods and pistons that weigh less it won't be as big of an issue cause its more or less counter balanced...

[@Heeltoe.]

@@04tacomaguy1 I'm sorry friend you're really off base. Size and weight of the pulley have nothing to do with the balance of the bottom end. The engine is balanced internally has nothing to do with the pulley. The pulley is balanced as well so it doesn't affect the balance of the rotating assembly at all.
