Worked on my C&L Plenum 2nite 56k warning!

Well I started polishing my C&L plenum tonite. Worked on it for about 2hrs. Can't get much better without taking a lot of material out. There are a lot of pits from casting that are just to deep[&:]

Tell me that you did a before and after dyno on this, PLEASE.

I would be interested in the extreme. Do you expect to pick up much HP?

Never dynoed with it on. I think I might get 1 or 2 more with it. It just had a lot of casting slag so I decided to shine it up.

I used 150grit paper to get most of the high spots out and then used 320 to smooth it out. going to do a bit more today and tonight and try to get the casting seem and some of the pits out. Just not going to go to much further. then probably run 600 to finish it up.

It is 100 times better then it was when I started

and seems like it will be worth it.
