Default Port & Polishing a Supercharger

Should I be overly concerned about all the metal filings that come from all the fine grinding that is done, or will a compressed air gun get rid of most once finished? I can always try to insert rags but then that may cause a problem should the grinder get caught in it by accident.

thanks

You need to take the supercharger apart to do this so I wouldn't be too concerned. The porting and polishing is all done on the body. You can properly blow it out when you're done. By the way.. you do have a spare right? This isn't something I'd attempt without a working backup first.

Have you read over Willwren'* guide? It can be found here. I found it to be extremely helpful. Use a Dremel with the flex head. A grinder isn't going to give you the flexibility to get in on the inlet.

I presently have the SC. off the car since I'm doing the Coupler. and no I don't have a backup. I hope that'* not a problem?
Yes I have read over Willwren'* guide since this is what prompted me to even attempt this project. As for cleaning, would a presure washer be a problem if I didn't exceed 3000 psi?

thanks

A pressure washer will be fine, but you'll need to replace your needle bearings before reassembly.

I must have missed the part that talked about replacing the needle bearing. Was that in the "coupler change" section or the "port & polish" section? I may be in trouble now!
Ok, I need to read up on needle bearings cause I don't know what the heck they are. Thanks for the info willwren.


I don't think I'm ever gonna get this car on the road. Frig.....

Replacing the needle bearings is already on my supercharger page. Look again.

Any time you clean or make a mess (either debris or cleaning agents/solvents) you wipe out the VERY EXPENSIVE and specialized grease in the needle bearings in the case. You MUST change them.

You SHOULD change them any time you open that case.

I saw it on the SC page willwren, I just didn't realise that it needed to be changed in that situation. Thanks for the information and I will read up when I have a minute. At this rate I think it'* gonna take me another month. I have to work this weekend again and I'm going to be out of town.

Thanks Again.

As far as inlet and outlet temperatures are concerned, yes.
