Orlando, FL. Customers normally ship me their blowers via UPS. My prices vary on how much work you have done i usually give discounts the more you get done at once. You will have to PM or email me for the work you want done and we will go from there.

Thanks,

Logan,

I'd reccomend taking a look at an S ported 94-95 and earlier ported 89-93 SC M90. Although the outlets may be sim the inlets require different attention than what yoru used to.

Also how do you recoat the rotors?

Damon

05-14-2010, 12:25 AM
Im aware that the inlets are different, im in the works with that. I use an epoxy powder coat that is superior to the factory coated gtp rotors. I have done dozens on the gm ones and generally see a 1.5psi increase.

Nice work... How long would the rotor coating last?

minichopper6hp
05-14-2010, 01:24 PM
It is supposed to be a lifetime coating. It will not peel or flake off like the factory gtp coating.

Im in the works with a member on here for porting to gauge prices, depends on the amount of time it takes to port them. For the coated rotors though, it would be the same amount of work so rotors are $80.

Thanks and if interested just email me.

What would be the normal turn around on the rotors , if your not backed up.... would it be OK to get a signature on the received item if i ship it UPS , just so i know you have it, and its not lost lol ? I need a few items powder coated over time as I rebuild my sc , and your work looks great ....

minichopper6hp
05-14-2010, 10:13 PM
If i receive the rotors around 5pm (generally when ups man comes), i can have them ready for shipment by around the same time the next day.

Ups requires signatures on all packages, so you will know when its delivered. Trust me, i send ALOT of stuff in the mail.

Thanks for the nice comments!!

Are the GTP rotors also teflon coated from the factory like the SC Eaton M90? Do you remove the rotors and coat them then re-assemble?

minichopper6hp
05-15-2010, 03:44 PM
The gtp rotors are coated from the factory with epoxy paint. I disassemble the rotor pack, strip the coating, blast the rotors, apply my epoxy powdercoat. I then inspect the bearings and seals (usually good) and re assemble and then time the rotors with precision measuring setup.

Out of curiosity, has the coating you use been tested with rotors that are spun up to 17000+ rpms with temperatures getting close to 400F.

A stock pullied SC will see about 14500 rpm's, but with the MPX setup some guys are OD'ing over 25%, and so far we haven't seen any coatings last that long with those rpm's and temps.

The coating i use is a high temp epoxy powdercoat, rated for 1200*F. The coating has been tested on customers cars on the gm version (same blower basically) with no issues. This coating does not come off very easily at all. Actually, because of the prep work done, its extremely difficult to come off. So i would not be worried about it flaking or anything to that nature. Like all other coatings, it can be scratched but only if you are not careful on the assembly. It is best to send your case so it can be matched but most of the time they are fine when fitted and timed onto a case of mine.

For the other question of putting on un coated rotors, i would not see an issue with it, to my knowledge they are the same diameter and spec rotor, just with no coating to take up the clearance. They still had to allow clearance for rotor to bore and i would not think that it would be different size for the coated sets, would make no sense to take off material and add it only to be at the same place you started. The whole premise is to take up the most gap you can between rotor to bore.

Hope that clears some questions up!!

The clearance on the rotor packs in the MPX cases is tighter than a stock M90 case. From what I have read and seen there hasn't been any coating that will stand up to the MPX case due to clearance and rpms more than temp issues.

Sounds like a good Idea but keep in mind Grand prix m90s dont turn near the rpms that the m90s overdriven on an sc do. I am putting my mpx together with a set of Gen V m90 rotors as we speak. if any coating will stay on the rotors the gen V coating should. Do you seperate the rotor pack from the bearing plate and put new bearings in and re time the rotors or do you just tape them off scuff the rotors and powder coat them?

minichopper6hp
05-20-2012, 03:09 PM
The m90s i do work on are not stock. The pulley size has been drastically reduced from stock to put out more boost. The rotor pack is completely dismantled, bearings and seals replaced upon request at additional cost. The rotors are blasted, coated and re assembled and checked for clearance on the housing. Gen v coating is better, its more of an abradable coating, but i have seen first hand eaton did not blast the rotors before coating and it too is susceptible to flaking off if it gets a chip started in it.

The coating on a Gen V is soft it doesnt chip. The stock pulley size on a tbird is 3.o which is a severe drop on a grand prix infact very few guys go that low. When these guys talk in percentage they mean it a 10% pulley is like a 2.8 on a gp in addition these guys are over driving the crank and the jackshaft pulley that leads to the blower spinning it 10s of thousands of rpms I would be willing to have you rebuild a set for me for my 95 ported supercharger if the price is right. just pm me and let me know prices

I am not putting it in my MPX I am having a set of GenV M90 rotors out of an 07 GTP put in it but I would be willing to take the ported 95 I have with mp inlet apart and post up results for everyone to see. This is a service that all of us need because most of the m90 superchargers I have had on all 5 cars the rotors are worn out at the bearing plate and the coating is blowing off of the rotors. He uses the same powder coat I am using on my long tube kooks to coat the rotors and it sounds like it would work perfect because of the heat resistance and may even make the rotors more efficiant and expel more heat. I am looking forward to having this done but I also want mine pulled apart and new bearings and seals put in the bearing plate. I will update the results when we get this done!

Most powder coating paint cures @ 400F so it will take heat in that range repeatedly and even a little higher. I don't see a need in using the more expensive 1300F paint on them as long as the pretreatment is done correctly and not just talking about blasting them. I would like to see a set that has a couple of thousand miles on them.

S_Mazza

This service sounds great. The important thing here would be price. The reason is that ESM has been rebuilding and recoating rotor packs for years and years. So this is not exactly a new thing. It is just that, until recently, it was cheaper to buy a low-mileage GM blower and switch the rotors.

What changed is that, now, those low-mileage GM blowers are pretty much dried up. The Gen V blowers are still available in good condition, but their bearing plates are different and the rotor packs do not interchange.

I think most of us are having a hard time swallowing the price of an ESM rebuild, but it seems reasonable given the amount of work, special tools, and the cost of a Magnuson rebuild. The question is, can this guy beat it?

One minor sub-question is, where did he go for 21 months? Seriously.

The simple answer to your question is i finished school, started a family and switched jobs. :)

But yes, the coating service i offer for the price is the best i believe and it is alot of work. One thing to keep in mind is that i still do this on my spare time so if you need something right away, this may not be for you. I do this after work at my full time job so it might take a week to get it done, maybe less just a heads up so no unreasonable expectations are made, i am not a business. Thanks!

A couple more questions for you.

1.) Do you have any references in terms of durability? Any satisfied customers running around?

2.) Do you have a good method for retaining the new bearings? I know the OEM method is one-time-only.

He is doing a set for me right now and as for a bearing and seal supplier I even have one not that hard to find. Motion industries out of Paducah Ky got me all the bearings I needed to rebuild my supercharger snout and the seal the same day for $23. They take the inner and outer circumfrance mic it and get the correct bearing type every time. Bonus they are made in the good old USA! I will leave feedback good or bad when I get mine back, he was going to finish mine today but ran into a hang up so I have to send another set to complete it, hope to get it back to take to stl on June 5

I hope so too, the bearings should be here in a couple days so when you get those rotors sent it can go together quickly.

Mazza, mostly gm crowd, there is a few although not in touch. I myself obviously a few years now doing 90 miles a day 5 times a week and going strong. The coating works. And for the price, really cannot be beat.

XR7 Dave
05-29-2012, 08:17 AM
Its a double lip seal. Perhaps you didn't understand my question. Is it designed to hold pressure from both directions? People typically use a double lip seal on the snout too, but it still is only designed to seal from one direction. The seal inside the bearing plate needs to seal from pressure on both sides, one to keep pressure out of the snout, one to keep oil from getting into the rotors. I know this has been a problem in the past with rebuilt rotor packs/bearing plates.

RIght. The part numbers they have listed for the seals on websites and what people have sent me before in the past have been typically the single lip seal. Im not sure how much pressure is actually present at the rotor shaft. All i can say at this point is that those seals are too expensive to be a viable replacement. Once question to ask is it really even worth it at that point if there is no evidence of them leaking to begin with?

I have had the original seals go bad on at least one blower. There was obvious leakage where the oil got sucked from the snout past the seals and into the rotors. Put it this way. If I sent my rotors to you, I would gladly pay another $50 to get the rotor bearings and seals put 100% right.

davec73
05-29-2012, 03:36 PM
Eaton m90 sc on the tbird ar capable of producing far more than 17psi of boost which is what the standard replacement seal will do. If the information on the site is correct the double lip teflon seal they are offering will hold up to 90 ps! Imo if this is correct it should eliminate snot pressurization so I am goint to order some and see.

Right. And when requested i will gladly install those seals. Until now i did not even know those seals were available and im sure neither did anyone else. Either way i agree 100% with you on the correct seal if people want to pay for the additional cost then i will keep that option available for them. Thanks for the input!

Well guys I got my rotors back from logan and they look and work great! The coating looks great used the ptfe seals good up to 90 psi and new bearings. It pushes around 17 psi and runs as smoth as a new one. the 17 psi # is on my car with stock heads, mp inlet, ported blower, intake, intake plenem, 95 manifolds and a 2.5 to 3 to 2.5 exhaust so it has all but headers and heads ported pushing 17 psi and maybe more but i didnt want to push it more than 5000 in fear of lifting the heads. Here are the pics, thanks again Logan!

Yes the bearings and seals in the bearing plate are replaced and the rotors are coated and re timed it is a true rebuild of an m90 rotor pack and they work very well!

this is the real deal guys if you have a rattle in your supercharger or just high mileage and low boost i highly recommend him for getting your rotor pack rebuilt. Even if you dont want the rotors coated it is worth it just to have new bearings and seals put in the rotor pack. With the upgraded ptfe seals you get 0 snout pressure! they are good up to 90 psi and the stockers are only good to about 17 if that.

I emailed and pm'd minichopper on this. I'd like to try out his rebuilt and coated rotors.
This looks excellent. Tightening up the tolerances between rotors and case seems to be the key.

Kindly provide me with a PM:quote for duplicating the "full boat" job above on my SCer.

Is that rebuilt rotor pack still available for $165 w/core?

Also if you have the capability to estimate the shipping from 60107 round trip.

Please PM with quote--

95 blower and plenum, stock and never opened as far as I know. 106K on it. Would like powdercoat black, ported, and rotors coated. Replace the bearings and seals too--and yes, I would like the PTFE seals.

Have a second 95 blower, would like a quote on too--powdercoat black, coated rotors, and new bearings/seals, but no porting work on this one. Please PM, thanks!

Anyone spray water/meth on the coating?
In my setup (On my ford explorer) I can't use an intercooler. Im almost ready to turn on water/meth injection as an alternative cooling method.

Im hoping that this coating doesn't break down with a meth mixture spraying thru it.

He is no longer doing this as work took time from his side business. I sent him a blower to be ported and coated, he had it for over a month and then sent it back.

Looks like he would have done a good job......but

If its still a possibility, i have a 94 supercharger with a rattle. It would be nice to get it, and the plenums ported and coated all at the same time. If you still feel like doing some work, i think it could help a community that's in dire need of a cheaper alternative. -Tom

My SC is on the way back. The transaction has been fantastic. Logan did the full meal deal ( bearings. heavy duty seals, coated rotors, and porting) on my early M90. I'm interested to see how the inlet can be opened up gently. I just don't have the skill or equipment for that.

So far, id recommend his service without hesitation. Just remember that due to parts ordering and available time you must be prepared to wait. I'm guessing express service would be difficult for him to do.

He is still dabbling in the rebuilds, for sure.

I'm pretty happy that he was able to process mine. Time line was 3 weeks to month for me. As far as I'm concerned, that's pretty fast.

As far as me still doing these, yes. I have settled in my new position at my job. That being said, i am not able to work on things every day after work like i used to. I sometimes work on the weekends. With Don's build, the holidays really set me back as i will not work on Christmas, new years etc. That makes the lead time a little longer. I actually just got 3 more chargers in the mail today, some m62's that i am doing for someone.

I took mt M90 case in to a local shop for polishing, and I covered the rotors very well. What I didn't do is cover the gear side of the rotor pack. So, the polishing guy was not careful at all and my rotor pack came back with polishing compound all but seizing the rotors. Not good.

I sent the rotor pack, and case to Logan for him to fix it up. PTFE seals, etc.
I rebuilt the snout myself, and have not re-installed the snout to the case. Im just waiting on warmer weather to install the M90 and spin it up.

First thing you will notice is the silencer holes are filled. Logan assured me he has never had an issue, as he is very careful to prep the surfaces first to make sure that it will not come apart.

Once the warmer weather hits, I'll post a review. I'll first install with the factory sized pulley, then a 2.8" pulley. Here's a few pics of Logan's handiwork. Definitely some labor went in to this.

Its not the best idea filling the silencer holes. Welding them shut can wrap a case but is a sure fix for closing them. Using an alum epoxy, which I use all the time for other things, is not what I would think is a good idea. It has its limitations. That blower case is going to heat up pretty good and the expansion rate of the epoxy and the expansion rate of the blower case are likely two diffrent animals. Basicly heating up and cooling over a period of time and being subjected to pressure I would expect the plugs to pop out. Most discussion here on the SCCoA lean more toward plugging them does nothing for performance and questionable on increasing the blower whine. With luck they just end up in your IC and pieces dont make it into your engine. This is my opinion, hope your blower works for you and nothing happens like that.

The problem is the blower is inverted so when one of those plugs goes, it goes straight down into the engine. Kind of expensive. Im assuming the guy who installed the plugs will pay for any damage should that happen.:rolleyes: Not trying to bust anyones chops here but installing plugs like that can be an expense you dont want down the road. How well the case is prepped is not the issue. its the heating and cooling cycles that will cause the plugs to loosen,diffrent materials expand and contract at diffrent rates, and the rest as Dave said is that. Like I said I hope you dont have anything happen like that but is it worth the chance.

Well guys,
I installed it, and have been using it. So far so good. I am obviously concerned about the silencer ports filling coming out and running thru my motor.

The SC isnt really any louder. Of course, I didn't see any real boost gain either. I am about 10lbs boost with a 2.5" pulley and have detonation issues due to high iat's. I tried water/meth injection, but the heat builds up too fast. I have a problem.

Due to the configuration of the blower, shoe horning an intercooler inbetween the M90 and intake would require cutting up my hood (And hood supports also) and adding a cowl, or doing a body lift. I think Im going to have to go back to a larger pulley.

If I were to get Logan to do another SC for me, Id request not to have the silencer ports filled. If for absolutely no other reason, peace of mind. Hearing from someone that actually had their filling come out concerns me, of course.

This is obviously in a Mustang ? Correct me if I am wrong. The intercooler mounts next to the rad. You run a supercoupe rad and intercooler bro. Other have when converting an n/a 3.8 to the m90.

The problem is, my Supercoupe M90 is technically mounted upside down pushing directly in to my intake. Im going to have to see if I can find a custom air to water intercooler, and custom make my mount.

This whole thing has been a great learning experience for me.

Here's kinda what has gone on. You can see the mount on post 1.

Thanks for posting this. Its appreciated.

Logan did track me down over at explorerforums and sent me a pm that he needs the rotor pack back. It was nice to see he went to the effort of pro acting rather than ignoring the issue. Lots of guys would probably have stuck their heads in the sand and hoped no one would contact them. Says a lot for Logan, in my opinion.

I have a spare M90, so I will be pulling this one off to send the rotor pack to him for correction when I do a test fit for my air/water intercooler.

I was nether impressed, or uninpressed with my rotor pack rebuild as I didn't really notice any difference in boost. I'm hoping that having this correction done to the rotors turns me in to 'impressed'.

I just browsed that quickly this morning. Is that the same person who ran the blower, but had odd boost levels that stayed at about 7 psi until 3,000 rpm or so, and then shot way up?

I have to second that, after over 2 months of checking everything else it has came down to the supercharger is not in good operating condition, the rebuild was botched and even the 2nd rotor pack was out of time and had metal shavings all over/in it and the webbing arounf the gears was all ground down.

the first rotor pack had the rotors on the wrong shafts:mad:
