Willwrens instructions are very good , I read everything thoroughly a couple of times and although it seems like a big job I think having a press is half the battle.Just read alot about the Sc as there is alot of info and I dont think youll have a problem.Mine runs great but I have a coupler and nose bearings I purchased and will eventually replace them but I feel confident now if I had to do the needle bearings,Although I cant get to the rebuild site either, I also get an error.

I have a 16 yr old girl going for G1 also , god help us and our Bonnys

I spent some time porting & polishing the */C today but ran into 2 problems.

1. I didn't realise that the whold gear and the turbine part came apart so when I was grinding down the outside part I would turn the turbine part to air out the metal fillings and in turn slightly scores the inside. See pictures below. I'm wondering when I polish the inside whether that will take care of it.
2. I use throttle body cleaner, varasol, and brake cleaner to clean up the inside but there are still stains that I just can't get out. I used the strongest tootbrush I could find and the pictures show how well it turned out.

I would not recommend polishing the large bores where the rotors spin. That would increase the clearence and reduce your boost. Cleaning is fine.

Use Castrol Super Clean to get the carbon out.

The scratches in the compressor housing will fill with carbon buildup in time and re-seal themselves.

I don't see any evidence of porting or polishing????? But you say you have? Didn't my pics on the website clearly show the rotor assembly removed?

i don't think its worth opening new thread for this one question... so here it is... will any speed shop port and polish a supercharger? or should i go to some place that works exclusively on superchargers? also, about how much does it cost to have this done.. i would definately never have the time to ever do this on my own

Well today I spent about 3 hours with a can of throttle body cleaner, brake cleaner and a 1/4 can of varasol, and cleaned the inside and outside of the */C and throttle body. As well I started to P&P with a carbide 'twist' bit and sanders. Based on the comments I received it sounds as though I need to do a lot more work. Thanks for the input and suggestions I guess Iím going to have to spend more time on it.

This is looking good Frank... looks like you are more cleaning up the casting flaws than actually going further into porting.

Either way..looks great.

Ok, I'm going to atempt this again over the weekend. These are the steps I've done so far:

1.I've used a carbide twist bit to grind down the rough edges and sharp casting on the outlet as well as all around where the depression is. unfortunatly I also smothed out the two small slits to either side of the outlet which willwren did not recommend. My mistake!
2. I went with 80 grit sanders along the depressed side of the outlet.
3. Cleaned the Throttle body and Inlet thoroughly.

Next step:

1. Polish the depressed area of the outlet. ...Should I use a stone or a flap wheel, or is there another tool of choice?
2. Sand down the inlet (snout) and throttle body with a flap wheel. Is there any specific grit I should use?

I really appreciate any and all comment.

Thanks
Frank

I took another look at willwren'* Porting & Polishing */C page and I'm unsure as to how the outlet and inlet ports are supposed to look once completed. Are they supposed to be totally smooth or still have somewhat of a rough feel?

Thanks.
