[@bryanhonea1981]

You don't need a smaller belt. You need a bigger pulley. Thall fix all the problems with the high boost and the heat.

[@raymondhjelleverli3720]

You cant drive a supercharger so fast Just stupid making heat and now power

[@RankTitan]

Exactly what I was gonna say

[@Berm_Blaster]

No you add a wastegate to the charge pipe lmfao. The only boost control you have for a supercharger is by changing the pulley size, that's it.

[@Berm_Blaster]

​@@raymondhjelleverli3720 a bigger pulley on the supercharger would spin it slower.

[@mastercricket7626]

You can only go down in size .. going up is unacceptable 😅

[@MArcin91]

Move throttle in front of supercharger, as in most cars with a supercharger (Hellcat, Chevy LS9 etc.). Something like a draw-througt turbo system. This will significantly quieten supercharger at low revs. The disadvantage is that there will be negative pressure in entire intake system and intercooler when the throttle is closed, so you will have to ensure intake is tight. At the same time, intake will not heat up as much because in negative pressure supercharger will have nothing to compress.😉

[@MArcin91]

@@StingrayOfficial I don't know if that makes sense. Superchargers in Hellcats, Corvettes and Mustang GT500s work in a vacuum and nothing bad happens.

[@CordobesErrante]

might also need a bypass valve

[@4port]

As said either move the TB to a draw threw, or put a recirculation /bypass circuit ..

[@scrappy110683]

Procharger kits are a belt driven blower mounted on brackets, they all have a bov to bleed boost at idle

[@duanebailey6253]

That's what a blow off valve is for. Helps bleed off the boost at lower throttle positions.

[@exploringpuertorico5052]

Put the stock pulley on the supercharger it's bigger and it will turn less

[@SilverCrestGamingHD]

If you put a bigger pulley on the charger not only will it make more tension on the belt it will also lower the boost

[@void_op5770]

Get a larger pulley to lower boost. If its making that boost at that low of rpm its going to make alot more with rpm.

[@OllamhDrab]

(Bigger diameter pulley, of course. Possibly making all the other connected pulleys wider like the unit came with to prevent that belt slippage, ...if they'll fit. )

[@Synthetic-Chicken]

Superchargers do generate a lot of heat due to constantly building boost even at idle, especially if they are stationary and not moving air over the intercooler, and top mounts, they are incredibly bad when stationary and even moving a heat soaked engine bay with turn the intercooler into an interheater. I've got a Toyota GTT Caldina with a 3SGTE and they come factory top mount, first thing I did was convert it to front mount just cause how bad top mounts are, that little intercooler would be better placed in one of the cut outs in the front bumper.

[@bambam23406]

The exhaust is open and rite there dumping to which wasn’t helping

[@3magikarpinamansuit281]

Top mounts work if there is a good scoop to bring air down, otherwise it is very bad.

[@Synthetic-Chicken]

@@3magikarpinamansuit281 Works good for a short time, again, I've got a car that comes with one factory, its good but once you've been driving for 20-30mins, the heat soak from the engine turns it into a interheater.

[@nickalderman5943]

you just need a bigger pulley. It will spin slower and make less boost. The heat is from over spinning it because of the size of the crank pulley, and that is what blows them up too.

[@OllamhDrab]

Well, you obviously have too small a diameter pulley for your engine speed there: remember it turns just about as fast as your engine in a linear way, modified by the leverage on the pulleys. So supercharger will spin slower with a bigger pulley on it, thus not give too much boost till you get the revs up. :)

[@grapsorz]

when you compress air it heats up. the same in a turbo. you have "X" amount of energy and you compress it in to a smaler space. the heat get "concentrated" if you have the throtlebody in front of the compressor you will not be pushing air thru it at idle. and you adjust the boost lvl by switching out the pullies.

[@sinformant]

#1 you may be overdriving the amr500 so it needs a bigger pulley #2 you can run a blow off valve in between the supercharger and the intercooler that stays open under vacuum and closes under boost and pick a vacuum source on the other side of the throttle body so at idle it will be open and then as rmps kick up and the s/c starts boosting it will close.

[@BOOT]

Sam don't like Blow Off Valves, LOL cracked me up every time he talked bout it and can't wait to see when he realizes later in this series

[@sinformant]

@@BOOT well not running on in a Turbo setup is one thing, especially with anti surge housings being a thing, but with a roots type supercharger where you have vanes that mesh together and have tight clearances, air pressure pushing backward through them is way more detrimental. Also the car is struggling to not lean out even on idle with the air being forced into it so a blow off valve is a must. Most all factory manifold mounted blowers have a bypass valve built into the manifold and most centrifugal style have a blow off valve inline on the piping. He is young, one day he may outgrow the fascination with the stu stu stu stu stu sound.

[@BOOT]

@@sinformant You don't gotta tell me, I'd of used a pulley RPM calculator before making anything. Compression is work=Heat! Richard Holdener played with one of these on the dyno not long ago and over spun it. Not watched Sam in awhile before i saw this series but i rem him always picking on BOV's And yup in th next vid he's busting one out LOL

[@billybreor1197]

Definitely get a bigger pulley will help with the heat and building so much boost also you can put blow of valves on supercharged engines

[@Billskins4dayz]

Definitely need a bypass valve to get an idle

[@duanebailey6253]

You put a blow off valve to an intake vacuum sorce to help with part throttle but as everyone else says needs a bigger pulley to make less boost.

[@MrOnigiriPanda]

Good content again Sammit, nice to fallow along while you try fun stuff and some r&d. nice read all the nice comments here giving good advice and knowledge.

[@Billskins4dayz]

the rotors are plastic coated they will melt eventually unless you cool them water meth would work people usually have them sucking on a carby so the fuel cools them

[@PlagueZZD]

Love the KEI car content! As others have said the ideal setup would have the throttle body before the charger and a bigger pulley to lower the boost.

[@elementmaniac]

Get a denso map sensor from a JZ or Glanza Starlet and it'll see boost (Should be the same plug). Also: intake through the headlight and make it a HELLKEI

[@kanethomo2483]

Sounded like you strapped a whipper snipper to it on that start up 😂

[@BassManBobBassCovers]

.5 BAR just bumping the throttle to 2k RPM is crazy for a supercharger. Why it's so loud. Would be cool to send it, but it might immediately fail without a supercharger specific BBV (boost bypass valve.) Superchargers do heat soak, but it's possibly being rung out way too much. 🤔

[@drgibs347]

22:36 all positive Displacement blowers like that are heat pumps they are always compressing air so they tend to need alot more air charge cooling than a turbo or centrifugal supercharger. Also, as far as boost control goes, most have a boost bypass valve like a small throttlebody.. could possibly use a wastegate plumbed into the charge piping

[@Nassim...]

Sammit is doing his hardest not to work on his abandoned S15 and his two road pink S12s. I believe he still has a black GTT that we don't have any idea where she is.

[@seangamblin1717]

Lol he’s just having fun bro

Yes a car update on all cars would be good I actually forgot about the other 32 also the give away stagea is still in his hands

[@Nassim...]

@@joshkeen6558 yeah that i subscribed to sam ever since he got that 32 🥲

[@texaspowerman]

Reverse the pulleys to start. You need to slow it down. You can also run a A/C electric clutch on it to be able to run it NA or boosted, we’ve done that on a boat motor with the little Amazon super charger.

[@Billskins4dayz]

the bypass valve will open on vacuum and close when it sees boost from the reference

[@AudiaciousLife]

weatherman here when you pressurize air it increases temp. Boyles and Charles Laws. turbo output also increases temps.

[@reecenyland2813]

Yes, superchargers make a lot of heat in the charge air due to all the friction. It could be getting extra hot though because of how close it is to the exhaust- if you could move it farther you should. If you want to make less boost, you should change pully diameters (smaller on the crank and/or larger on the charger). You could also add a wastegate or blowoff valve to the charge pipe to relieve pressure too, i think turbo smart makes an electronically controlled one.

[@Jpcoadwell80]

Mad boost …………😮 can’t wait to see this wagon leave 11’s down the road 👌

[@DISCOSHOEBOX]

The original Asin AMR 300 and 500 supercharger has Teflon coated metal lobes but it is to my understanding the Temu version appears to be remanufacturing these with plastic rotors.

[@NelsYouTube]

pretty stoked can’t wait to see how that van run when Sam gets it dialed in

[@bread3643]

Kei car content let’s goooo

[@R32Danny]

You need a bleed off valve (Bypass valve ,waste gate) they run off vacuum and put the Throttle body in front of the supercharger should work alot better. Maybe a larger pulley to slow it down for now to get everything working

[@Jon64scale]

Sammit the diecast car is sick but id still Yamaha R6 swap , Turbo , aero/wrap , suspension/wheels beat the heck out of it and have way more fun 👍

[@conceptautohouse141]

commented on your last video, these types of blower need a blow off valve with a very weak spring to act as a bypass valve. It will stop the blower eating itself and fix all these idle and heat issues

[@garnethart1137]

Put a bigger pulley on charger to cut down on boost at idle. That should also help with belt slip

[@mrfatbobrider1969]

Probably be a good idea to run a fan at it for some cool air while sitting idle, same as dyno always got cool air running at the front of the engine

[@Billskins4dayz]

clutches on those 660s look like a 5.5 inch indy car clutch would fit xd

[@kittyztigerz]

racegate is useful release trapped air when you get too much boost and air cant escape it become super hot where cant touch it and installing racegate to release air reduce heat issues

[@ardennielsen3761]

21:40 when you install the air intake side of the supercharger, put a fuel injector in front of the blower intake so the fuel cools it off... fuel line from OEM fuel rail "T-fitting" to added injector, put a brake peddle switch on the gas peddle to turn on the injector. a big injector that is nearly the flow rate of the engines normal injectors. ... more so get the added gas peddle switch positioned to turn on right where the engine sees 1psi boost. 90% of normal driving is in the -15psi to -8psi range.

[@ardennielsen3761]

a water mister/fogger on a momentary button as well along with the fuel injector, to cool it off before a big drag? would also clean out any carbon that builds up on the low end of the slight over fueling from the static flow/rpm range single injector. if that car has any O2 sensor and a basic OBDII system? should still be trying to self correct for fuel or put out a lean/rich fuel code.

[@user-zv6fr6jn7c]

you need to run a blow off valve to release the pressure at idle

[@Auto_Pulse_CarNews]

@sammit, I recommend using a 2:1 pulley ratio. This change will reduce the RPM by half and slightly decrease the horsepower, but it will significantly increase the torque. Lower revs will also help in maintaining cooler temperatures and prevent heat soak.

[@christopherharris6005]

Awesome video as always Sammit.

[@Berm_Blaster]

Grind Hard Plumbing did a project with I think Hoonigan where they installed a small supercharger similar to the one Sam used and it was extemely loud like that. Couldn't even hear the engine running.

[@johnt.848]

It just needs a pressure relief valve like a blow of valve on the charge pipe. Set it to 8PSI or get an adjustable one.

[@steliosz2762]

Put the exaust back put an airfilter plus a heat shield because the cat is next to it.

[@J-D..]

Bigger pully Sam and a dump valve to remove pressure on idle control it with vacuum

[@scrappy110683]

Leave the pulley alone, install a bov and plumb it to vacuum, you need the bov open at idle, most superchargers have a bypass valve that stays open at idle to bleed off boost

[@ryanleeg8521]

I need long form build videos, I love the info in this

[@scottloersch555]

100% agree with a good bulk of the other comments you dont want to go a smaller belt you want a bigger 4pk pulley the one you got is to small witch is what is causeing the massive over boost issue bigger pulley less boost plus will solve the tension issues also id swap back to the 7pk pulley for now and test it

[@TheJetadv]

bigger supercharger pulley will solve your problem as it is over spinning and that is what's creating the heat 🔥 🔥

[@syroncoda]

Digging this build and defo want to see more cheap car builds! Junkyard build when?

[@gateaccess818]

working on this tiny motor with the flywheel makes you look like a giant in comparison. lie a mini car for real. imagine putting that motor setup in a gocart.... that would be sick

[@Nukes25]

Like many have said, bigger pulley to reduce low rpm boost buildup. And on the other note, while big dream car builds are fancy, sometimes its more fun to build up a nugget. Currently building up an 06 suzuki every turbo 5spd rwd over here, cant wait to get it done and on the road for fun, without breaking speed limits 😅

[@2111Chriswarfe]

add a blow off valve or bypass valve like a procharger setup it will get rid of the crazy whine at idle.

[@ethangobey7722]

you could add a blowoff valve on the intake pipe to help with over boost and i think this thing needs a link ecu

[@user-fk8nw8py7n]

I know you have a spare K-series engine You know what's up

[@loganleborgne420]

You mean a few K20 and K24...😉

[@5150Failure]

also my super charger is after my throttle body. a bigger pully on the s/c will make less boost a smaller one will make more. so you could always play with pully size

[@bigdadgigachad3042]

Plastic internals, not sure it being super hot is going to work long term. Is it piped backward or something? Does it have to be positioned in a certain way? Hope you get her figured out.

[@theprogamer3365]

You need a blow of in order to not heat sock the intercooler. Because when you let of the throttle the boost has nowhere to go so it will ether go the way it came (supercharger) or it will repel the energy in heat. In this case it's a bit of both because in some

[@josephbarker4436]

You could try a stock turbo ecu, and you could do a water to air cooler and run methanol threw it to keep temps good, also a larger pulley will drop boost

[@tkx0202]

someone get sam a propper moveable workbench this man is always working on the floor

[@SoulPurposeGarage]

That's cool man! I didn't have much hopes for that supercharger but it actually makes boost lol impressive! To regulate the boost you can mess with the pulley sizes but you'll also have to get different size belts as well

[@Andy4543]

Sam you singing is too funny bro!!!

[@enorym]

I had a power steering pump sound exactly the same on my mustang when it went bad lol.

[@garnethart1137]

That amount of heat is probably what contributes to plastic delaminating from rotors. Also regarding the noise,every video I've watched with these chargers they are all super loud.makes u wonder what causes them to make so much noise. Too tight of tolerances on rotors?gear mesh? I'd like to see if there's any metal in oil even after running for such a short time.maybe look for shiny spots on rotors caused from tight clearances. Is there a way to cool rotors with fuel? Meth injection before the charger? Can't wait to see next video.(with bigger pulley on charger)

[@gregoryosborne1407]

Turbosmart makes something called a boost gate which is in essence a wastegate for the charge pipe

[@welshywilliams1692]

That tensioner is genius

[@Lesminster]

Maybe some different ratio between engine and supercharger cause it's spinning too fast?

[@leoayroles1411]

U can put a dump valve to controle the pressure in the intake.

[@240heaven]

Hey Sam great video as always, I think you should check the charger as it warms up and find out where that heat is coming from, a flur would be perfect, also I suggest adding a computer style fan under that cooler pulling toward the engine 🤙

[@marshallrounds1126]

Yeah go to the bigger pulley that should help lower boost and add tension. Adding the filter will quiet it a bit but sounds like others in the comments know a lot more than me when it comes to the throttle body moving in front of the charger somehow

[@Shoo-fly]

@ 4:30 he knew he f'd up. Lol

[@travisstamp7428]

If you have a hook-up at a machine shop, see if you can get metal internals to replace the plastic ones. It would probably sound a lot different too. I hope it lasts long enough to be a cool project.

[@kermitahnenerbe3722]

Hi some people don't use wastegate, they control boost pressure with a dump valve. Maybe you can put an e-gate and make it close when you hop on the throttle.

[@AustinLeiphart]

you can add a blowoff valve and let it blow down under light throttle like most procharged cars do when building boost that they can't use.

[@TheJamm93]

ideally with that setup you would want some kind of bypass valve to take the load off of the supercharger at idle/low revs

[@wheelsofsteel]

Put the throttle body before the supercharger. Being wide open it is trying to push all that air against the closed throttle body while at idle making all that heat and noise.

[@wheeln24-79]

This makes a log of sense hope he sees this

[@baltazard133T]

You should have kept the 7 rub pulley on that supercharger and you should have gotten a much larger one to underdrive the system as well. that would have helped greatly to manage heat and the high boost pressures. Those cheap superchargers lose 80% efficiency as lost friction heat anything over 4 PSI of constant boost pressure. Another reason your supercharger casing is getting so hot is because you're having to keep the belt tension so tight to keep it from slipping because you switched from a 7 rib system to a 5 rib, this is why superchargers have such wide belts is for the grip on the pulleys...

[@davidjumper8739]

Bigger pulley with help with the boost and adding a bov will help. I'm mind blown with how this is working I thought for sure it would break.

[@TheTreasure_HuntSpot]

You just need to put a blow off valve on the pipe. Thats what everyone does with these! Also if you put the stock pulley (if it's bigger) it will lower the boost and it'll run cooler. But like I said if you put a blow off on the pipe it'll definitely run cooler and won't force boost at the throttle plate and cause heat

[@rushdrift]

Larger pulley will fix the issue and yes there is a supercharger waste gate they call it a bypass valve usually its used with a combine set up with turbocharger but just a supercharge set up would be a waste, yes supercharger do run hot in your case I think they were spinning way too fast causing stupid boost

[@kridselot7383]

if you make to much boost ... use a bigger pulley to change ratio from engine rev to charger rev

[@kemargooding4960]

Plus it won't be so hot at idle and the air would be blowing through the valve instead of just being in the pipe pushing against itself

[@jasonbourne9357]

I always thought you needed a BOV for idling. For example my TIAL BOV is very slightly open on idle and snaps shut on positive pressure

[@taz275]

Bigger pulley will reduce boost, and possibly your belt slip aswell

[@Akiro0925]

You need a bypass valve back into the intake of the supervharger and it'll be quieter and idle properly + boost control.

[@SKOMPAS]

The Kei car doesn’t need a Link Ecu, it needs a FMU that raises fuel pressure with boost

[@JaysElectronicTinkerShack]

move throttle body on the charger inlet and put a bigger pulley on the charger should drop ur boost a bit

[@KylenTakeshi]

It looks like the exhaust is dumping straight down. Maybe the hot exhaust is also getting sucked back into the supercharger

[@attaurrehman-el5cy]

17:10 the car is in gear and the trans does not have any oil and may also may be making alot of noise

[@peterkopacka5741]

and what about adding some kind of wastegate? that extra heat looks like not good lubricating - maybe wrong oil? too much oil? good luck Sam

[@HIDNotfound]

She needs a larger pulley.

[@Billskins4dayz]

Don't go smaller = more heat

[@Altered.Images]

Small pulley, fast spinning. Big pulley, slower spin, lower boost, won’t overheat

[@sombrero4316]

bro you must have made 30 psi reving that thing at one point, I was worried you're going to blow it up.

[@Danny-T87]

I would do some oldschool Fins on the pipes and the charger sense it’s so fare forward? An maybe it’s own electric fan on the hood to pull air from the top Why not 🤷🏻‍♂️ I’ve been trying to find them for newer cars and im thinking of doing it for mine…. Can’t beat it!!

[@Blaw07086]

Need to change to a bigger pully so the sc is running so fast will help with heat

[@mht525]

Bush style. Great to see Yugo and Well done . Bogan Aussie style. 🙏✌️🇦🇺

[@Grumpy_Stiltskin]

Pulley size controls boost, larger diameter on the blower will spin it slower. Blowers do make a lot of heat, especially if you're spinning them to fast. It does sound terrible, you sure there's oil in it?

[@MS-hn1ek]

I just looked the compressor up on Temu and it’s says their those compressor is for 1.0 to 2.0 liter engines. That could explain why it makes way too much boost on oidle on the little 660cc engine. 🤔 Just thinking loud,don’t say it can’t work with a Link ecu and a blow off valve.

[@DomBounty]

You should look how the bmw MINI R53 supercharger setup is, in theory it has 2 throttle bodies... a main thottle body and a bypass valve to skip the intercooler for idle.

[@kanenstuff]

Think its good and helps you learn new things and hope I can see it when I go to the merch shop July 9 but dont worry I wont bother your work, aussie respect here.
