Thanks, no it doesn't.
I looked at some of the upgrades from 928motorsports and others (like the billet wheels, "better bearings", etc), and a lot of it had bad reviews, with a few good ones here and there. If you google search 928 motorsports and powerdyne bd11a rebuild and billet wheels you will find lots of threads on other forums, even a few on here if I rememeber correctly. Most people had issues and the ones that didn't still couldn't spin the powerdyne much higher without eating belts (internal belt) and it destroying itself. They just aren't made to make much more than 5 lbs of boost reliably (probably because of internal belt design and no oil lubrication). Some people did get good results from the billet wheel though, made more boost with the same pulley they said.
I just didn't want to risk it and spend the money to still not be able to spin it faster and for less than the price of rebuilding and a billet wheel, I bought a lighty used Procharger. And the D1SC has great reviews from people using them.
the Bd11a is good up to 5 lbs or so and lasts a long time if not over worked, but you don't want to spin it faster, that is when you start running into issues. If you search, most people will say when it comes time to rebuild, it isn't worth it if you want to make more power

Lol I just picked up a rebuilt bd11 with billet compressor wheel.....don't make me feel bad.....
If I just run the stock psi it should be a good durable unit, no?

The bd11a is a good unit for under 10 psi/ish, with the billet impeller. We used to use these back in the day on 5.0 Mustangs and never had problems at 9 psi ALL DAY. Besides the bmw v8 does not like high boost, so no worries. I am going to locate an AI port in front of my S/C so it can stay cooler for the long hauls.
I am not saying the BD11a is awesome, but it does do the job on our cars nicely.
I suppose if money was not an issue, I would go bigger.
I figured that, i'm not trying to break records here, just get a little more omph from my m60
I picked up a rebuilt bd11a with 0 miles on it and a stage 2 billet compressor wheel.
I want to see this when it's done, looks like a awesome project
I think you should be fine as long as they used quality parts and bearings
Most of the people I knew who used them (also on their 5.0 mustangs and a few camaros) had problems and would have to rebuild it alot when they pushed it past 6 lbs. They usually would only be able to get 7 lbs by adding the billet wheel, but once they pushed it for more, it would have problems and need to be rebuilt frequently. Mainly the internal belt slipping.
I think it is a good unit if you are going to run 5 lbs or 6 lbs. Only reason I am replacing mine is because it doesn't even make that anymore and I didn't want to spend the money to rebuild it when I got a better supercharger for close to the same price as rebuilding it and I wanted to upgrade anyway and add an intercoooler.

i FINALLY fixed my misalignment with the belt this weekend. it kept throwing the belt off, usually on longer trips. not sure if it was the heat that was stretching the belt and then it would throw itself off or just the slight misalignment i knew i had, or both. i made a thick washer a wedge shape, like a angled shim. stuffed it behind my belt tensioner bracket and turned the shim till the belt straightened out on the tenioner pulley. well see how it holds up. now i need to figure out how to tune this thing and i should be alright for a while. need to get it to stop maxing out the maf with the resistance, and then tune the rest of the map. it runs real rich all over right now. hopefully i dont toast the cats before i fix it.

rich is better than lean lol
exactly why im not worried about driving it around. it goes like a bat outa hell when it actually decides to run right.
-Alex
I can second that, but now with the newer tune and mismatched maf I am back to throwing fireballs. I have almost enough money to get the new maf and piping built. It does light up the night though, and anyone behind me usually stays back once I light the sky. I only have been testing it at night, lately.
Someday, before summer, I will have it as a DD, hopefully.
I haven't had the belt throw for a while now, so I guess I have some made improvements.
Ahenry, if I'm running the tune that was meant for my s/c through a war chip, with the "stock" injectors for the kit, etc. On "stock" psi, I shouldn't be running into any maf scaling issues or really any tuning issues, right?

you "shouldnt". i dont have a powerdyne charger, so i assume thats where my issues running at stock psi lay. OR it has to do with the DV, which miller claimed the car had when then tuned it, but ive not seen a dinan powerdyne kit with a DV on it. i believe that my charger flows more air, but it shouldnt matter since the maf is calculating all the air regardless.
all we can do here with custom put together kits is "give it a shot".
-Alex
It's looking more and more like my ESS V2SQ chip (and 803 maf) will be available in about a month and a half to two months. Probably longer than you're willing to wait, though.
Note to those that want to avoid the resistors... running an 803 maf without resistors leans the car out A LOT. There is no longer the "overflowing the maf" issue but I had to go from 30 => 42lb injectors to get my afr's back in the 12 range (aem uego readings... so hopefully mildly accurate).

hey guys
i pussed out and pulled the kit. these days, with it being my only car, i need it to be reliable. dont have the time to get the kit sorted. just gonna put it aside for now. might get back to it someday.
ill keep up here to see what you guys accomplish

That's a bummer. Issue(s) you couldn't overcome?

no i could figure em out. but i drive 30 minutes to work, 30 minutes home, every day. no extra car to drive. this is it. if i had the time i could figrue it out. the bracket needs to be strengthened, the belt alignment/tensioner needs work, and the tune. i just dont have time to mess with it at this point in my life. its on a shelf for another day, or if someone wants to buy it, feel free to make an offer. i really want to get myself into a turbo i6 someday ultimately.

Damn that's a bummer. Well one down...

^^ Total bummer. Well it's not over yet, you still own it and I have been inching forward on my new tubing/maf mount. Hopefully I will be able to DD the machine this spring. My goal anyways, though I have other cars to work/drive around in the nicer months. If I was in a 1 car setup, would probably pulled the s/c off and drove reliably to work also. Slowly chip away at the problems and soon you will be having fun again.
exactlyyyy right now im happy with it and its reliability, dont have to worry constantly. feels nice.
-Alex
Can someone please make or send me a bracket for a m62tu.
Thanks.
I tried to put my mod list in my sig, but it wouldn't fit.
