I like your style. Can't recall the last time I saw so much negativity on one of these threads, and all over some guy who just wants to ask some questions and mod his own supercharger. I am really curious to see what that porting does, and I applaud you for rebuilding it yourself. There are some threads on here where people act like rebuilding these chargers is a dark art that can only be mastered with an engineering degree. I would much rather buy one or two broken spares and learn something about it, so long as I know I can make something semi-functional.
I'm into it- my car is a shitbox and that's part of what I love about it. There is nothing on my R53 that I will feel bad breaking, modifying, replacing with some chinese amazon crazy stuff, or bumping into my garbage cans backing out of my drive. I am gonna drive the **** out of it all winter and love it. If I had bought a new mini, or had a car worth more, it would serve none of those purposes. I don't dislike the guys who want to spend $10k trying to make their low mileage R53 pristine, but those guys should realize that not everyone has the same goals with their cars.
When you get your sensor straightened out, put the ported one back on!
Because to rebuild one "right"......you need to know what you are doing. There is a reason there are companies out there that do nothing but speciciles in rebuilding superchargers and air ends. Because to make them last, you need to know what you are doing. Sure, anyone can "rebuild" one (if you call rebuilding one just putting new seals in them).....doesn't mean it's going to last. I could probably "rebuild" a jet turbine in my garage......doesn't mean I would trust it.
And then there is the issues with using JB weld to close up intake ports on the supercharger......please tell me what about that makes any sense if you are wanting to INCREASE airflow? So you open up/port the main inlet port to gain a slight amount of flow.....and then you close up two other ports? Why? Does this make logical sense to anyone?
Any then there is the issue of having two big plugs inside your supercharger made out of JB weld......what happens when (not if) one of those plugs comes lose and drops down into the rotors when they are spinning at 14,000rpms?? If you are lucky it just locks up the supercharger and leaves you stranded on the side of the road....if you are unlucky, catastrophic failure. If this was a good idea, the shops that rebuild them would be doing it.....but they don't, because "common sense".
These are the reasons people are calling him out on some of this stuff........it makes no sense at all.
But...his car, his money, his time........he can do what he wants, but just don't get on here and try to tell people it's a good idea to do the same thing to their cars, because it's not.

Won't argue with you about the flow path on the sc but obviously its beneficial to design it that way or aftermarket made superchargers like the tvs would have them in it WHICH IS DOESNT BECUASE ITS NOT BENEFICIAL. I will say it one last time , you probably get .5 psi through those silencers, BIG DEAL ! I guarantee you I made up that lost volume with my porting,easily. Those are silencers , all THEY DO. They aren't there for better air flow or power. They're there to adhere to strict noise standards for an engine..
And what would you suggest yo cover those ports better n smoother? Can't weld them you will warp the **** out of that flange in there or over heat seals or something .YOU are obviously unaware too of the strength of the jb weld and your lack of mechanical experience shows as you sit here and try to start a pissing contest with me...my car has NEVER left me stranded once so I must be doing something rite consider I bought it sight unseen , used , 200k+ miles , unknown mods and history and within a month transformed it into MY car and made it more reliable . 16 months of owning it , 20k miles about and 1 track day , I have yet to have a full breakdown where I couldn't limp my car back at worst case.. even then thats happened 2x only now. My tensioner issue here i caused and then I had a crank pulley separate..
And I NEVER advised ANYBODY to do this porting mod yet , I'm not even 100% sure how effective it will be..it will be easy to tell if the porting has done anything with all my data logging i will do so I will post up my result and either this is gonna be a AWESOME win or a fail and just some lost time , big deal. But how do you know until you try ? Find me another forum where someone's done this ??? O you can't? Ok , well I'm going to do it then. Guinea pig or what idc. Its fun for me , I'm learning as I go and in the end I could wind up with a more efficient supercharger made out of a formerly BROKEN one , so again . What I got to loose ? I have a completely stock one as a back up too so I covered my bases.

Well, whatever the consensus, I enjoy seeing someone working by trial and error and figuring out the answers to their own questions. Much less fun and interesting to see someone who has done a job 1000 times and already knows all the pitfalls.
Sweet...I got the seal out no problem and the bearings are perfectly fine..so I ordered all needed rebuild parts and now ille be stuck with 3x superchargers so i guess ille part with one of them as I really need to recoup a few bucks from this.
but check out how toasted the seal is, daaaaaang.
After ready through this entire post.....I've come to the conclusion that 90% of your issues are self induced.
anyone who adds an aftermarket part is in this group. Keep doing it!

But in all fairness we had to rig back on my tensioner without the tool AND it was already kinda shotty.
but yes had I took a little extra time all this could have been avoided. BUT in all fairness each time the car came apart it got better parts like new coolant hoses or all new sensors belt and now a tensioner, o yea and a ported sc
Agh well, no point crying over spilt milk...
that is a big reason I usually work on my car alone so things don't go over looked and I try not to work on it when its late at like 2am. Thats when I tend to do dumb dumbs.

Every home mechanic made/makes mistakes, would be a damn shame if you would stop working on your car because people tell you not to do it anymore. And he might have done it "half assed" because, maybe at the time he didn't know any better.
I applaud MiniManAdam for being so open about it and making his situation discussable over the internet.
We used to have a crew back in the day that I was apart of, ie my signature. I think we may have to open enrollment for Team Halfa$$ again!!!
