Hi all, I just sent an SC off to M7 for their port and polish. It's $695 plus $25 for some internal shipping costs. Of course, after I came back from dropping the package off at UPS, one of my e-mail enquiries was returned. Turns out there's this guy who just port and polishes Eaton SCs. Any Eaton SC.

I sent him an e-mail, and he quoted the Mini M45 SC port, polish inspection and fluids for $400! That's three bills off!

I don't know if the work is better or worse. Anyone out there want to try them out to see?

Matt

Bob's reply....

Yes we can port those for $395.00 That includes the porting and to have all
new fluids added and to be inspected.
Thank you

I committed to the work with M7, and I'll follow through because I said I would. But I wish I'd seen this earlier.....

 

Interesting. I feel that m7 has the highest quality in many of their products. You may pay a little more, but you know it will work. The old saying holds true: "you get what you pay for"...

 

hey thnx a million 4 d info!!!
had u asked bob what type of fluid he uses and is it better 2 use a better fluid?
i wonder if d supercharger has especific settings for d mini?
when do u get urs back from peter?
did u pull it out yourself? how many miles on ur mule?

 

who does the M7 porting?

 

IIRC, one of the gains in '05 MCS bhp is due to the SC coating, changed to the same coating previously used only in the JCW kit SC's. Would a port and polish remove this coating? I've dropped an email to them to see about a little feedback on total number of MCS SC's they've handled, and prospective gains for MCS owners.

Cheers,
Matthew Z.

 

The coating is only on the lobes, so the case work would not effect that. The only one I'm aware of who coats the case is Endyn.

 

I had two PMs indicating that Dyno Bob Steigemeier (or however it's spelled) is the one that does the M7 porting.... So now it's like the Webb head, get it from Randy, or get the work done by the guy who does it, for less. But Randy adds a cam and the delta isn't such a huge percentage. If it's true that Bob does the SC for M7, then it's about 40% less expensive for the same work!

Matt

So,you do get what you pay for, it's just sometimes the deal is better or worse than you percieved!

M7, it's not my fault! Blame Google!

 

Hi Guys....


Yes, Stiegemeier is our source for porting the SC. Steigemeier and M7 has an exclusive deal for MINI related SC porting, IE if you want a Stiegemeier ported supercharger you have to go thru M7.
The work done on the ported MINI SC is an evolution of a normal porting job
that could be expected out of their shop. We are currently on the 3rd generation porting design, taking the envelope further for better performance.
For more info feel free to call us any time.....

sounds like the old catch-can-22

 

Sounds like one of you doesn't know what 'exclusive' means

 

The M7 mod sounds interesting. Anyone have a ballpark of how many labor hours a supercharger take-off/reinstall would run? I know shop rates vary, but what do you guys think, maybe 4 hours total? That is a total guess...

 

Anyone???

 

Put front bumper in service mode.
Remove intake stuff And IC.
Don't know how far in this goes.
Remove belt etc.
Drain Cooling system (water pump on back of SC)
Remove SC (heard it's a pain, but I don't know as I haven't done it yet).
Put it all back together.

3-6 hours? 50-120 per hour... $150 t0 $720 in labor! At $150, I'd pay. At over $250, I'll skin the knuckles.....

Matt

 

Thanks Matt. The shop I use charges $68 an hour for labor- so it isn't TOO bad. Anyone have a better ballpark on taking off and re-installing a SC?

 

Matt- I forgot to ask, any idea when you will get your SC back from M7 and installed? I'm anxious to hear how much of a difference it makes.

 

I spoke with Peter today and he said that on a JCW car they added a 16% MTH and the SC mod and got an additional 17whp. He also said that a customer in Portland with a much more modified car did not get any gain. Peter chalks that up to difference in dyno, etc. But the jury is out as how much gain a highly modified engine will improve vs a JCW type modded car. I am very interested in this because if i could get 10 more WHP for that price I would do it. For 5 more whp probably not. All those of you doing the SC mod I'll split the cost of a pre post dyno with you for your car and consider it R&D money. Maybe a several of us could go in so it is $10 from everyone. There are group buys why not share the cost of research and testing?

Since you brought up the car in Portland, here is what the tuner (Joshua)had to say on another forum:

"I have one (M7 SC) on the dyno right now... seems to lose 12hp over a stock blower..."

"The car has: header, cat/b, ported head, Schricks, extrude honed intake manifolds, M7 AGS, M7 blower, 18% blower pulley, 4% crank pulley, Alta TMIC. Runs 1.9 bar of boost!!! I ended up getting 229whp compared to the stock blowers 231whp... That was after an hour of fine tuning. It's a pretty agressive map too! I was running water spray on the intercooler. The temps were 185 CLT and 80-90 IAT although I was not watching charge temps which I'm sure were through the roof!! A/F was 11.4:1 going to 11:1 right before redline."

"I just work for a software tuning company. The car isn't mine and I didn't do any of the work to it. I think it has a Milltech header and cat/b. All I know is I tuned it two weeks ago with a stock blower and now it has this new M7 blower on it and it makes a little less power. The owner of the car had the AGS flowed on a bench and says it flows 20% better. We all know that doesn't mean much though."

"... I don't know what they cost but I wouldn't pay for one!!"

This is with the same dyno and same tuner. It made less power, not no power.

I don't care who's or what product you choose to purchase. This is just information from a different perspective.

When I spoke to the owner.....

He told me he lost 5hp not whp, on a car that's already at 260hp I would
calculate that to everything from atmospheric/temp differences to variances
from run to run. But the big question is, how many more hp would you expect at 260hp new SC or not.

The other thing to remember is you do not get higher boost pressures with the ported SC, but more cfm's allowing the charge to run cooler at prolonged
high rpm runs IE. track events, racing, canyon running etc. It's a proven technology, that we have proven on less bleeding edge setups like the JCW
car that gained a substantial amount of hp.

but I'm pretty short on time. Im in semiconductors, and Semicon West is next week, so my time is shot till the weekend.
I've got an AGS on the way for a marketplace sale with the TB and the heat shield coming with the SC.
And I'm looking at a PLX R-500 that arrived today and I gotta figure out how to hack the wiring harness to hook it all up. Maybe I can get connectors from AMP and make a UniChip like drop in.....

I'm pretty sure I can close it all by December, but it will be close!


I'm gonna think about data logging dyno stuff. Talk about simulating real driving conditions, why not measure during real driving conditions?

Then I can get data from lots of mods... But that would be so much more work, and I've also got a 7 month old....

Basically, I like to have fun, and immidiat gratification plays a significant role there! I may just stuff it all on and start logging and tuning!

Matt

 

as you probaly know, it isn't easy to get AMP connectors; however they are very good about getting out samples if you approach them from that perspective.

 

I'm waiting for Ross-Tech's BIM-COM software. It is a dyno on-the-run, an A/F logger, it will read & interpet diagnostic codes, and more...

http://www.ross-tech.com/bim-com/comingsoon.html

It will even let you reprogram your dealer modifiable options...locks, lights, etc.

How cool is that?

 

It's also been vapor-ware for a LOOOOONG time with no release date in sight, and that's all you get when you ask for one. I really wanted it too, but I doubt we'll have it anytime soon :(

 

And patience isn't one of my better skills! Lots of OBDII stuff does dyno calculations. But I'm not happy with the data rates on the OBDII connector (can only get faster than 1 Hz with very few variables, like 4-5, and only in a streaming mode that not all loggers support). I think the PLX I got does 10 Hz, and that should be enough for some dyno like runs.
Then there's the G-TEch and it's bretheren..... they have accelerometers in them.... Damn more $!!!!

I'd love BiM-Com, I'm just afraid I'll be dead before it's released..... I think the Bim Com Yahoo Group is over 2 years old!!!!!

First, I am a huge fan of Peter and M7. I have found his advice to me to be realistic and forthcoming........I was not throwing him "under the bus". I thought it was great of him to tell me straight out that on highly modified engines you may or may not experience large gains and then he proceeded to give me the two scenarios and let me decide what I wanted to do which was find out what others have experienced and that remains......

I contacted MiniSpeed in the UK and their SC upgrade nets a 10% increase in "flow" but that in and of itself tells me nothing.

I am just glad that this forum exists so that I have so many "enablers" for my Mini addiction:smile:

 

I think it depends what is done to the car already if you'll see a gain with the ported blower. I currently only have a 15% pulley and a remus exhaust on my car and would like to throw on a ported blower along with a GIAC chip and JCW injectors. I think that combo will work very nicely for what I want out of my car

So depending on what you want this could be great or a waste of $$
