... no seriously WHAT PART are you questioning if he used 40 grit sandpaper.

the edges of the silencing vents to be filled

I would cut a groove into the wall to make the channel shaped more like
this: =====< >======
instead of this: ======l l=======

thanks cody

Maybe we should just forget about filling the silencing vents...

Is that yours?? That sucks man.

Oh snap! what happend?

When I took the blower off to replace the gaskets and stuff now, I just found it like that. I had no idea that it happened. That chunk was just MIA. So I said screw it and punched out the rest of the quickweld. I really don't understand how that happened because the rest of it didn't come very easily. It took some work. Anyway I really didn't notice any difference in how loud it is after I put it back on vents open and it isn't supposed to have any effect on performance so I'm deeming it pointless to fill them.

so... that quickweld chunk is somewhere in the engine? scary...

ok, i'm reviving this thread to get some feedback.
here is my stock blower:


from what i'm seeing of all the pics the V isnt really enlarged that much. Also, most of the cnc port jobs remove the bar and port it all the way back to the bypass hole. The lim is only like 4" long so unless that too is ported all the way out i dont see how porting anything past the bar would help.
As for the V, is there such a thing as too aggressive?

here is what i'm thinking for the V:



I will post pics of the lim later.

a pic of entire blower:


LIM with a line to show where i think i'm going to port it.

I wouldn't even go that far with the opening. A sure way to do it is to simply angle cut and smooth the edges where they are and basically turn the arrow head shape into a triangle. Don't make the body of the opening wider or longer - just take care of the back area. The angle cutting is very easy work for a machine and quite a bit more work to do by hand.

I would do nothing to the LIM as far as opening it up unless you plan to fit an IC now. You could just trim the front edge of the opening (the side away from the BBV port) to make sure its clear of the blower outlet after you port it. There's no reason to open the intake if you're leaving the blower partitioned.

Make sure you grab a couple shorter bolts for the bottom of the blower driveneck so they don't stick out into the outlet area after you port it.

well i had already started the lim before you posted so i just kept going.
here is the lim finished (except for the studs in it). still a little bit of carbon in the runners, but i'm out of cleaner for the moment.


Im getting ready to start the blower. Here is a revised drawing of my plan (does it look alright?):

Matthew,
What kind of tools are you using to do the work.
Just curious, do you have air tools ?
If so, what are you using to cut, grind and blend the cast aluminum. ?

no air tools. just the neighbors dremel with 420 cut wheels and a grinding stone attachment.
I've literally been working on the car all day today, and plan to again tomorrow.

Did you ask Travis if he still has a LIM for sale.
He advertised 2 L67's for sale last month, but he probably moved them quick IDK.

progress shot of blower:
still have to finish removing the bar and then a final hand sanding to smooth it more.

hmm looks pretty good dogg.

wow! interesting work.

are you using shorter polts now on the snout?
(2 of the polt holdes are shorter now and open to the interjor of SC)

planned on it but couldnt find bolts like them at the auto store. i'll have tom check somewhere else later. main thing right now is getting the car running so i can go to work and school.

For her blower port and polish; I think the wife made some thick aluminum washers on the lathe the correct length so that the old bolts could be reused. I assumed she would just cut the bolts, but she assumed she would make some washers. Differences in how guys vs girls solve problems i guess.
