AMR 500 Supercharger Testing - is it as Good as the Internet Says?

The AMR 500 supercharger is a 500cc supercharger that sells for a very cheap price at around $200 on Ebay / wish.com. In this video, I argue that people make it out to be better than it actually is.

[@HatersGarage]

[DISCLAIMER] I've been told a few times that I'm an idiot and I should have known this wouldn't work and blah blah blah, keep in mind this is a review of a CHINESE "rebuilt" AMR 500. Which are basically used and worn out with a fresh coat of paint, reason being the average person would most likely end up with one of these. I'm mostly making fun of the listings you see of these claiming that they're good to 2.0 - 2.2L, which is laughably wrong as we saw. It could MAYBE make 1-2 PSI with a tiny pulley, but it already ran nuclear hot with the pulley that was on it. I've also had some questions about the 13:1 AFR, saying that it should have been richer for boost. We never actually made any boost with this thing, so there was no need for a richer mixture. Richard Holdener is experimenting with the AMR 500 if you want to see someone use one correctly. All hail Richard Holdener.

[@tutunci]

i am sorry brother but keep in mind that 500 says how much cfm wich indicate the max volume of air the blower will be able to make. at 5000 rpm your car will need at least 750cfm . these measures say u are doomed with a 2.2l. u need a eaton 62 or a eaton 90 . wich have 620cfm and 900 cfm . u can tune those with the size of the pulley gear.

[@tutunci]

yje more u compress the air the more u need a 9liters intercooler.

You're not going to guilt China into changing their advertising. Besides people who are building a vehicle with a mini-supercharger are already aware of China's marketing antics and know to adjust expectations accordingly. I wouldn't want to discourage people from taking on a project with this product, it's the learning process that has value anyways, not so much the contraption that results.

[@paulwheway4553]

ents If you had actually done your research first. Blower displacement x drive ratio ÷ engine displacement per rev ÷ 2 due to intake stroke on 4 stroke. This gives you your boost ratio Then you remove 1 atmosphere from this to get your boost pressure. So. 500 x 2.33 = 1165 2200 ÷ 2 = 1100 Then divide 1165 ÷ 1100 = 1.059 1.059 minus 1 atmosphere = 0.059 bar pressure. This is at 100% efficiency which never happens with superchargers so problem in the minus pressure wise. These superchargers get a bad reputation but it doesn't help when youtubers like yourself, donut media and grind hard fit them wrongly without doing any simple research

[@ExUSSailor]

The crew at Donut Media just installed one on their VW Cabrio. It took it from 81 wheel hp on the dyno, to, 46.8 wheel hp.

[@chinupofficial4421]

That was the wish one. He may have bought a wish one I'm not too far into it but they have legitimate ones that work pretty good for small engines. I use one in my golf cart build to spool a mini turbo. Granted a good one of these is 380+ USD but the power increase was damn good

[@sexyfacenation]

Percentage wise that's a great improvement, just the wrong direction.

[@JohnS-br3xk]

There’s a lot going on here, that revolves around overestimating and miscalculating. These superchargers were intended for and fitted to 600cc engines. The Amr500 displaces 500cc’s of volume per revolution. But that is not taking into consideration of efficiency range of a roots style blower, and the air density of the blower output. The reality is roots style blowers are only efficient at low speeds, so just because it’s “rated” for 15k rpm, does NOT mean it’s actually displacing more air at that speed. Roots blowers rapidly heat up the air from friction, with a linear increase in heat directly tied to rotational speed. The reality is you wouldn’t want to spin it faster than 6000-7000 rpm. Which is around 60cfm of airflow, and your 2.2L engine at redline is displacing at least 160-170cfm of theoretical airflow. That 2.2l engine is breathing far more n/a than this blower could ever keep up with. It’s really cool to see you mock this up to your car, but this really in no way reflects the real world use case or performance of the amr blower. You definitely could have done these airflow calculations beforehand to find this wouldn’t be a good fit. I in no way intend for this to be hostile, and I hope there is value taken from this.

[@JohnS-br3xk]

Also the leaking oil happens from overfilling the units, and could have to do with the speed your turning it at as well.

[@HatersGarage]

I had assumed it wouldn't work, however I see people putting these on their cars all the time, and Chinese Ebay sellers are selling these as if they will work with these larger engines. the video basically to get people to stop doing it.

[@LivingMyBoostLife]

Jerry may I hassle you with a question which you may be able to answer. Say I have a very inefficient 2.5 litre, 70hp, small carb, low compression, not built for performance. That thing is surely not consuming as much air as this Plymouths 2.2. What does this 2.2 make stock, 140hp? With far less power to start with could my feable 2.5 make use of such a small supercharger? I know there's better options but I'm just considering the Aisin rip off for novelty factor 😀

[@tjewett1967]

@@LivingMyBoostLife The AMR 500 is completely useless on any engine over about 1600cc. It doesn't matter how much horsepower your engine currently makes it all has to do with volume. Jerry pretty much spelled it out. Not sure how you could possibly read his post and not get it.

[@johnbelwell2461]

@@LivingMyBoostLife well, the displacement is there to stay so this supercharger would remain insufficient, if it's just inefficient due to low airflow and fuel then swap the carburetor to a bigger and better breathing one and the things would drastically change. You'll need a bigger carb in either way even if this one worked.

[@mikecorleone6797]

Bro.. smaller pulley, lighter oil in super charger.. i have the same one on my 67 vw bug and i can keep up easily with 1914 vw’s with my baby 1600 engine.. getting on the freeway is fun and my boost gauge shows 5psi wide open which isn’t the best but definitely a huge improvement for a 44hp vw bug..

[@boosted0079]

that's exactly what he needed was a smaller pulley. those little blowers ain't gonna push that large of an engine very well, especially while using that big ass pie pan of a pulley lol. They claim to be rated up to a 2.2L, but I would be very suspicious of it don't that on the stock pulley. a2a intercooler would be a must have a well after overdriving the blower because it's going to create heat.. but in reality, those amr blowers are cheap junk.

eaton m62 is over double the displacement per revolution amr 500 500 cc per revolution = 30.512 cubic inches per revolution m62 = 62 cubic inches per revolution equivalent would be 1016 cc per rev

[@Mitchd03]

Its an amr500, The 500 stands for 500cc. In theory, one revolution pumps out 500cc of air, not including any losses or temperature increase or any other... math. That's just the size. And a 2L engine has 4x 500cc cylinders, that take air every second crank revolution. So the 500cc supercharger needs to spin four times just to fill the cylinders in one engine cycle (two crank revolutions) I was considering adding one to my 1L 3cyl and I thought it might be too small for that lmao.

[@petehira1594]

Your calculations are pointing toward smaller pulleys which may be the answer to the issue. I turbod' a 1.8L using a 1.2L turbo and it added a crazy amount of power simply because it spun so fast.

These superchargers were originally manufactured back in the 50's for carbi 4 bangers that made 30-50 HP from the factory. It works wonders for the cars they're made for. I've got one on my 58' Renault Dauphine Gordini and it's made it that much better. They don't do shit on modern cars. They can't keep up; restricts air flow that modern cars have these days They're only good for 60 ish year old 4 banger engines.

[@craigengelman1369]

i use these superchargers all the time with zero problems . you have to change out the oil from the factory to acdelco 10-4041 Synthetic ($12) . you can not have any leaks at all with the piping . when you do the pulleys you want at your motor at redline to be at 9k to get 6-7ish pounds of boost .

[@Tristanwendt]

I run an Eaton m90 from a Pontiac on my Vw and it works great. Your best off picking up a junkyard blower like me.

[@koolHalo3clips]

I saw it advertised for 0.8 to 2.0l displacement. You need a smaller pulley. I think it would be worth trying at least. I saw it works on Del sols well with 1.6l engine.

[@HatersGarage]

The advertising seems to be a tad random. I've seen people on forums running them on 2.2's claiming that it made a difference in power, however I think it's placebo. I don't think It's worth it to set it up for a smaller pulley.

[@koolHalo3clips]

Yeah they really work best on engines 1.6l and below. I think the inlets and outlets are too small on the supercharger. They are only like 1.5in opening. I’ve seen people make bigger flanges but these things were ultimately designed for a 660 cc engine. Id love to try this on my 1.9l bmw but I don’t want to waste money if it doesn’t make boost.

[@HatersGarage]

@@koolHalo3clips Yeah I forgot to mention in the video that I made 2.5" flanges for it to match the charge piping. You could put a micro V belt on it to spin it faster and make some boost for your 1.9l, but I wouldn't expect more than 5 PSI. However then you run into the problem of it possibly leaking like mine. The math suggests that it should be enough for a 2.2l, but they seem to be very inefficient; as in they don't seal well.

Had an Eaton M65 on my 4 banger 8valve BMW E30 (M40B18). Got 6 psi of boost at around 5k rpms. Although couldn't feel horsepower increase, throttle response was way better and much much torque from 1200 rpms. With a welded short ratio diff and weight reduction,it was really fun.. Later swapped to 6 cylinder M50 with a snail 😂 and became man😂....

[@HatersGarage]

Yeah the bad thing about superchargers is you use a big chunk of your extra power turning the supercharger itself.

[@EthyrDesign]

The other thing no one in the comments is talking about is the fact that scavenging has changed with the additional airflow, so without mods to the exhaust pipe, the frequency/flowrate of exhaust has increased, changing the length of the runners to correct amount may be helpful. (Since the supercharger isn't relying on pressure differentials on the exhaust side)

[@curtiswiancko693]

You could change the input and output to a larger size might help it get more air flow they are restricted from out of the box

[@plightn]

Glad you tested it! :) Good info!

[@tynkky]

The pulley ratio is 1 : 2.33 so AMR 500cc can make you 1,165 liters of air per one cycle and 2,33 liters on full revolution (two cycles). That means that it only slows you down cose there is no boost ;)

[@James-qr6rp]

Sounds sick can't wait to try one on my car

[@Flumphinator]

It literally made his car slower.

[@glennjames7107]

It's leaking gear oil from the blower. This is because the seals in the blower (I'm assuming) are designed to operate in a positive pressure environment. If what your saying about the blower causing a restriction in the intake at wide open throttle, then that would mean that the oil seals in the blower were exposed to a negative pressure environment for however long it was ran at wot. Thus drawing gear oil from the blower casing.

[@turbosaleen347]

[@dbdbdb1111111]

Im sorry you had to learn the hard way. You did gain experience and thats priceless. I looked into it myself and all it does is it makes a lot of noise and makes you lose power. Just to give a heads up even proper electric turbos arent there yet. Restriction is the issue. They work awesome the 2% of the time you use them, but for regular driving will block air flow. People negate having a well in order working vehicle foremost. Keep fiddling

[@paradiselost9946]

an electric turbo will never get there. a few simple calcs on the power required to simply compress a given volume to a given pressure in a given time is a dead giveaway. unless you have an alternator the same size as the engine itself and are willing to dump half your produced power into that generator simply to drive the "turbo" which at this point is a centrifugal supercharger, not a "turbo". and then that also requires a motor driving said compressor capable of delivering teh power required... 50 hp is a lot of power to drive an electric motor with. ever seen how big a 50HP electric motor is? and thats only going to give you 25-30 hp anyway. yippee... those big blowers strapped to drag cars? they might be absorbing up to 1000HP, simply to flow enough air to GAIN 1000hp at teh shaft... meaning the engine actually had to make 2000 hp over its stock output, 1000 of it to drive the blower. go find me a 1MW electric motor that can be lifted by hand, and doesnt require a 100T crane and wide load truck with special permits to move around. find me the 1MW generator required to drive it... a belt and a pulley is FAR more effective than generators, batteries, speed controls, and electric motors. as is an exhaust gas driven turbine. electric supercharging is a delusional pipedream sold by advertising teams and charlatans with no concept of basic physics, electrical theory, or mechanical designs. and they rely on the fact that you dont either!

Also there is nothing available as for rebuild kits at least here in the US nor Europe to rebuild these air pumps their selling everyone as a fake supercharger!

Then here's another option for ya.....but these things aren't something that you bolt on and you have instant power let alone no problems with them, that's a definite answer!

[@myrmeko]

You'd probably blow it up, tbh. If you ignore the actual real volume of air the Geo Metro sucks and presume it has a full rotation of sucking air, ignoring how much time it takes to open the valve and what's the lift and how much actual air gets in, it would suck in 3078L/min of air, at 993cc at the max RPM of 6200. The AMR500 at 14000RPM (i wouldn't risk using a clone at full RPM, tbh) could pump 7000L/min. So that comes down to 18.72 PSI. In reality, it wouldn't be that much, because it doesn't suck no way near as much air. So around 70% i'd say it's a fine enough approximation (i have no idea where i could even look up the timing graph of a Geo Metro), so around 13.1PSI. So... That, from the base 55HP, would boost it up to around 105HP. Which is decent, but it's already twice the power and i dunno the limit of the internals.

[@JOOLZNED]

I have an AMR500 on my 600cc bike it works really well on 10 lbs of boost and I have another pulley that gives me 14lbs, I wouldnt use the supercharger on anythig over 1600cc and thats running the supercharger very overdriven, they are probably at their best under 1200cc

The AMR 500 has a working rpm of 16,000, a 3:1 pulley ratio on a 1600cc gets you about 8 psi, as long as you're not holding revs over 5500rpm you're sweet

Well could work for a 2-2.2 liters , if that engine does not rev high , and has a not so good volumetric efficiency to begin with. But I do give you , that they could be more descriptive about what the charger can and can not do. Interestingly i found these advertised as max 14000 rpm and 500ccm per rev max. That supposedly yields 7000 liters of air per minute , where it would still be Just making loss overall. Assuming an engine with 10 to 1 compression ratio to begin with , a 0.2 bar boost is well whitin reason as a small performance bump. That would mean an engine that can not take more Than 5800 liters of air. Given a 2 liter 4 stroke that be a redline of approx 5500 rpm. If you got a smaller engine , like a 1.4 liter one , it could rev to about 7500-8000 rpm. As rpm climbs and volumetric efficiency decreases , the actual boost pressure will rise. So actually you need to have a blow off valve set to 0.2 bar , and you need an electric or some other type of valve after it. Thst needs to stay shut above a certain rpm. That depends on the engine and its ve curve. Basicly a 2 step blow off setup. Thatway near peak tourqe rpm , where ve is about near its highest , you won't overboost and have knocking. And at higher rpm where ve would start to drop , you get a slightly rising boost curve. That makes the powerband expand to higher rpm. And thats a decent tune. An other solution is decreasing the compression ratio of the engine to begin with. Then you can have higher boost without knocking , and not need a multi step blow off valve. I do plan to get one my self, for an 1250 or so ccm fiat engine. For that ,its a good match.

Two of them would probably make a few PSI. A beefy intercooler would probably keep things cool without water meth as well. At that point you may as well just get a bigger supercharger for a similar price, I've had about 8 people tell me to get a Eaton m62

What you have their is the Chinese Re-production units. You can get AMR500 Units that are "genuine" refurbs, although take the term refurb with a pinch of salt. I always rebuild the unit with new bearings and seals( $40 in brgs and seals, takes about an hour) I See everyone install these incorrectly. They are a positive displacement unit, so the throttle body should on the INTAKE side of the charger. These units do not work well in a Blow-Through configuration (They are not centrifugal). I, like yourself, Installed the Unit like you did. The engine LOST power. I Then did a ton of pipework and mounted the throttle body BEFORE the charger on the Intake/ Air filter and i gained 40hp (Talking a small 1.3L Engine here). The unit also runs a lot quieter and sounds like a charger instead of an air raid siren.
