Drivetrain Ported SC, good for 10% HP gain?
YOU were doing great up until this point. 
If you want to lie to yourself that's okay BUT the WHOLE community shame LB. 
If you actually do stop it is because there is NOTHING left to do.
On a serious note, LB is correct that gains can be had under a variety of budgets. Most important is that the road maps lie within this forum on proper order, parts combos, what is tried and true and an occasional good deal in the marketplace. LB has certainly contributed in this regard.

is that while there was a lot of learning that happened way back when (and in internet time, that can be a recent as a few months), many of the lessons that were learned was forgotten by the "collective". Seems like information just doesn't have the life it once had.

Do you think if someone needs to have a complete SC rebuild, would it be worth the extra $100. to get it ported?
What would you say is cheap cheap price for the FSD's???
I honestly don't know...
I just caught up with this thread, I have been gone all weekend. I understand that this has been gone over before, but there has been nobody that I knew of that could completely rebuild the M45 until now? Plus with the 02's and 03's now approaching 100k and more miles, it seemed like a good time to bring it up again Do you think if someone needs to have a complete SC rebuild, would it be worth the extra $100. to get it ported?

got it back
OK my supercharger is back here are some pics 
and a nice little emblem they added
I do not have before pictures so nothing to compare it too.
when I spin the pulley the supercharger feels tighter ,as all of the slop was removed. I had some binding when I sent it out and one could hear the inner workings of the supercharger. Now the binding is gone and it is much quieter when rotated by hand. I thought that the binding mite be the water pump drive, but that ended up not needing to be rebuilt. So in the end it cost me 595$+S&H for porting and rebuild not cheep, but seeing the end results a good and fair price.

I had the Endyn modified supercharger for a few years, in addition to the porting and pressure relief port closures; Endyn applies an anti-friction coating to the interior case. I also had a special coating applied to the lobes. I was able to see different states of the porting processes with the supercharger disassembled and the precision with which the details were executed was exacting; all lobe edges matched their corresponding case features without radiuses. These photos are borrowed from Endyn and are not of my SC.
I can’t give delineating dyno data, but can say it helped attain a 60hp/45lb-ft torque over stock baseline in conjunction with a 19% pulley, Endyn head, 380cc injectors, and Helix/GIAC flash. Logs of IAT from other stock vehicles and my car on the same course, traveled on the same day, at legal speed limits, showed higher temps on all others. Unfortunately, the coatings and porting were not enough to keep temps down on the dyno or high demand road use. With the options available today, I believe money could best be spent elsewhere, but if one can afford it, why not leave no-stone-unturned.
I forgot to add this story, the Endyn SC also had resistance when turned so I thought it best to run-in the SC before installation. I fabed this rig and couldn't resist putting my hand on the intake port out of curiosity while it was running; the vacuum was scary intense.

Let us knqw what you think once you put it back on. Looks good.
Hey thanks for following up Let us know what you think after reinstallation

Looking good Qtip.
Do you have any higher res photos; I see something in the 1st pic on the right side of the SC inlet.

the hole for the vac tube
I'm just curious - how's life with only 7 fingers?
I've been thinking about this a lot...
But without more data, this is just a guess....
Matt
the SC is much quieter but with all the mods that went on at the same time, I cant tell how much power the porting gave me.

Thanks for the follow up.
Is it possible that your SC grinding or worn noise is gone as opposed to the whine?
