![M90 Supercharger Intercooler Plate Fabrication(Design & Assembly) [Part 1 1UZ W2A series]](http://i.ytimg.com/vi/NoWK8O9c7Gg/mqdefault.jpg)
Got my '98 Grand Prix supercharger apart now and a friend told me about this procedure. Doing mine tomorrow. Most informative. Good job!
I had a '99 GTP for my first car when I was 16 and sold it when I was 25 or so. It was a torque monster... I never did the pulley on it because I was worried about breaking something bigger on it. With a pulley you can expect about 320 ft-lbs. People rarely change the supercharger oil, so I'd highly recommend you doing so. The oil is a special oil, so buy the right kind.
@@UA-camHandlesAreStupid its not special oil its just lower drive oil for a outboard motor. grab a bottle of lucas marine and it says so right on the bottle
@@evanrosario I'm saying it's not engine oil is all
10:00 Scoring inside the case. Yuk. It will only mean a mild boost leak. If it concerns you, scrub those clean with Soap and Water, brake fluid then acetone and naptha. Use overkill to get down in the grooves and remove every bid of oil. Use a toothbrush and clean lint free rags. Let it dry real good. Then with a Razor Blade or the edge of a credit card, scrape regular JB Weld into those grooves, and only in the grooves. Let it dry a few days before assembly. Sand High spots with 400 grit sandpaper.
Nitromethane funny cars and dragsters use this method on their superchargers, it works. The JB weld stays in place. I've used it to fix a Weiand 144 and thousands of miles later, the scoring is still fixed.
It looks alot worse on camera then it actually is due to poor lighting ect. I have heard of people using that technique to fix housings before though. Its good to know that people have success repairing them.
sadly i dont even think thats scoring. its probably just the manufacturing tooling marks just like on the sealing surfaces.
i was looking at those like man i bet you smoothed it out some it would have alot cleaner flow. but removing material will also lower boost. but increase flow potentially. and lower charge temps.
filling and smoothing it out would be the same as 2 stroke case porting and stuffing so its pry the best way to go.
@@chehystpewpur4754 If you've ever taken one or more apart, yu would know that is scoring. Even the maker of this video says it is.
A great video mate! Everything is very well explained and done in a timely manner. You now have me looking for a M122 for my LS400!
Thanks mate, i appreciate the feedback 😁. A M122 would be sweet, i may even go down that route as well in the future when I decide to chase abit more power. Would be a perfect match for the 1UZ 👌
Dope video.
Some funky slipknot playing as the snout went back on lol totally dig it
Before you cut those 210 mm bolts down thread a die over the bowl cut the end off and then thread the die off will save you a lot of headache in time
He said that’ll give ya sloppy in ya charga 😎🤘🏻 that had me going
Good Video Brotha and nice drift car you got rockin! keep it up!
doing this for a 4.3, intercooling it and pully swaping it should turn out nice
People like you that do videos on the superchargers and turbos are really awesome these days because of you know the fluctuating of gas prices and stuff and the over marketing of electric vehicle.. general electric vehicles like diesel trains for instance are very efficient in generating the power right then and there and delivering it mechanically and efficiently no matter what the fuel type is.. I'm just almost thirty and already feel really because times are changing very fast.. and the information age is or rather has turned into dis information age.. ten years or more of my life is what it costs to have the education for electrical engineering and that has nothing to do with automotive.. or my time to even do that
Awesome video mate and truly appreciated. Seriously look forward to seeing more from you in the near future.
No worries mate and Thankyou for for the appreciation. I will be dynoing it soon to see what gains it made 👍
Wish I could get my hands on an rwd m90. My s10 would be fun with an rwd m90 on it. The m90s in the fwd have too long of an inlet
Great video dude! Very informative, and filmed well enough. Keen to see more👌🏻
Nice. I'm doing research on getting one of these on my 350z DE engine, I've really only seen one guy do it and he made 350whp with it.. (they make about 250whp or so NA). I'll be doing this mod while I'm messing with it, why not?!
cool video! Im gona use a m90 on my 2.7L mopar
Really cool, now I know how..thank you.
try making a harmonic slot vent by adding drop of metal dot dot dot pattern so u get happy middle ground, still hve slots but not wide open instead 1/2 as much. Like an instrument design.
one of my first jobs at a repair shop was finishing the job on one of the 3800 supercharged cars. the boss couldnt stomach the smell of the oil or figure out how to put it back together because it had been a while and the only one hed seen.
i laughed having done a few gasket jobs on them but never smelling the oil.
i opened it and was like yeah thats bad but gear lube is my least fav but this is up there with it.
end of the day i had it back together cleaned and serviced and running pretty quick and he realized he got a great mechanic. he didnt wanna pay better after a few years so i planned my leaving and got my chance. his shop went under some time after that.
but im glad you pointed out the smell. some people literally cant stomach it. and is the worst part of messing with these.
"Dead Fish Beer Cheese" ?
Amazing video very informative and helpful good job
TY
Wow, simple inside them, thinking getting one for my vt, seen them for sell for like $250 on marketplace. Wot else U need to do to add one, cheers Graham
i found this supercharger for around 130 bucks is it a good deal ? btw its used and i think only came with the head it self
Cheers m8....
Heck yea
Great vid, mate. Been trying to make up my mind whether to put a supercharger in the commodore since the v6 packed it in? Are they high maintenance? And what do you have to watch out for if buying one?
Thanks, in my opinion they are relatively low maintenance. I would just ensure it spins freely with no rubbing or strange noises coming from the rotors, that aswell as the rotors dont have visual damage to them or excess teflon peeling. It may be worth inspecting the coupling and replacing if it feels like it has excessive slop when spinning it by hand. I hope this helps.
3 words: Brushworks Slick Sixes. Nuff said.
Wonder i could make a manifold for that to fit on 1200 cc suzuki bandit.?
That would be pretty wild!
Did I miss the part were you cleaned and greased the bearings
I did mention about cleaning it in the video but yes i must have forgot to film regreasing. Good pick up.
Should replaced them not just lubed them
🔥🔥
I need to shorten my M-90 drive snout also what ratio is cool to run on my Dyna
hi man!
wanted to know one thing.
I have a 2001 Mercedes. 2 liter compressor eaton m45.
is there any point in doing porting for such a baby as m45? and about the oil for sc. Do I need a special oil or is transmission oil suitable?
Hi, I dont have any experience with the m45 unfortunately.
As for the oil Eaton do use a supercharger oil specifically so I would stick to using that.
Next time drill out the corners before you cut to prevent cracks
Hey great vid, it’s really well done. Now time has passed just wondering if you would still take the time to do this? Was the results worth your time?
Yes absolutely. It helped drop the intake air temperature significantly making the M90 more efficient.
10:41 if by now you took the plunge and arrived here, should go without saying but with some people you just never know, be sure it's clean no particulates at all otherwise you might as well drop sand in your intake and hope like hell nothing goes wrong, not smart.
Awesome video, what were the results from the dyno?
Thanks. I havnt put it back on the dyno yet but i did make a video about how it helped with intake temps if your interested in checking it out
@@Brodorsport did you see any change in boost pressures up or down
I found no noticeable change in boost pressure.
That was awesomeee. Man im trying to put an m90 in my SC400 but im trying to figure everything out right before I go for it. Do you got a Guide on how you did your Supercharger and its install as well as needed parts and cost? I would love to get more power from my 1UZ.
Trinidad Swank Glad you liked the video man, im going to do a walk around video soon and discuss what’s involved and how i went about it. Stay Tuned 👍
i'm going to be putting an eaton supercharger from bullet cars. they sell a complete kit for about 4500 dollars us. if you really want to get good power out of it though, you'd be best served porting the heads and putting in new valves/ new gaskets for everything and i'm still considering a piston upgrade as well. it will probably run you around 5 to 7 k to get everything figured out with a tune( optional) and idle control solenoid plus miscellaneous stuff.
What size pulley wheel is that?
I've heard the m90 can run pretty hot with a smaller pulley.
I have a 1uz and just bought an m90.
Want to get the most out of it without flogging either then engine or the charger
2.45”, it does get high intake temps with heavy acceleration. I would recommend a 2.9 or 2.8” pulley for a safer result. Or possibly run a intercooler setup to drop the temps. My haltech ecu is able to pull ignition timing with high temps on a correction map is how I manage with it atm.
comment 26 showing: If u r bolting 1 face onto another face, they need to work in a small change. The amount of metal under 1 screw tab & the next tab rounding the mating plate should vary, so small tab med tab small tab med tab. U will get better seal vibrational hold & the screws hve diff length easy on 1s & deeper 1s, making taking off & going back on less likely to b screwed by bad screws.
you just tap the hole and move on. its aluminum you can even weld and retap to same size. or put a stud in the 2 short holes and not worry about it either.
Would it be possible to fit the M90 to the 6G74 on my Pajero NL 1997 model and what needs to be upgraded on the engine itself.
Its definitely possible. You would have to fabricate your own manifold to fit it or find a company that already makes one if possible. Im not too familiar with the 6g74 to recommend upgrades but i would suggest installing a wideband air fuel ratio gauge to monitor it and ensure the tune is sufficient
Theres a spring in the snout. What is that for?. I cant find any info on it. It doesn't work for anything tension wise. Ive lost mine, on my 94 thunderbird m90.
It loads the bearing to keep it from walking the pins away from the coupler.
Hello! Can you tell me how to restore the coating on the rotors? Thanks
have to send it in somewhere
Great vid. Big question here though. Did the porting make any power gain?
Murray Finkle I haven’t dynoed it again yet but i will soon. Stay tuned!
It won't do much as he didn't port the inlet. The inlet and elbow that attaches are the biggest restriction on these blowers.
This is done mostly to match the efficiency of the gen 5 blower as much as possible. Not so much for power alone.
@@boosted0079 it can be if you do it right. Look up Brushworks Slick Sixes.
@@dutchylt I guess technically speaking, if you're increasing efficiency, you're going to gain power output lol.
What's the chance to find a shorter snout? Need one for this but has to be shorter.
Best bet is to have it machined down on a lathe in my opinion.
Look into the early 90s GM 3800s. My 92 Buick Park Ave has a blower with a smaller snout. I think the Gen 2 3800s and up started using the longer snouts.
@@Brodorsport yeah that ended up costing about 470 to get done, but I'm sure it'll be worth it in the end.
Great video but you could used better lighting.
Thanks man. Yeah you’re right I do need to sort that out. Thankyou for the feedback
What sealant did you use?
Loctite 515 master gasket
That's like 90 wait that goes in your dif
How much power did you pick up?
I haven’t dynoed it again yet but i will soon. Stay tuned!
@@Brodorsport Thanks for the reply.
Rinse Rinse u don't want any of those shavings
Too easy!
That the end of "Alcoholic Anonymous"
Smells like joe biden
