Thread: Supercharger Outler Porting

I have another supercharger and am planning on doing the following mods:

3.4 pulley
headers
intake
plugs
Tunetimeperformance tune
considering 1.95 rockers also

I have access to a bridgeport at work so porting the outlet would cost me nothing except a little bit of time. Is it worth the time for me to do it with this setup? From all I have read, it doesn't sound like I would gain any more power out of it, but I was hoping it might help with keeping the knock down when it is all done. Thanks for any input.

If its a GenIII, there is gains in porting and polsihing. GenV, there is no gains, its perfect the way it is and then some.

Pretty much in a GenIII port job the main goal is to get rid of the snout bolt boss's that poke into/extrude into the outlet, and open it up just a LITTLE. Doing machine work to the "slits" on the out let is up to you.

I did, and it gave my old GenIII a very unique sound with a engine rev. and under boost. It screamed louder. You can leave the slits alone, and be alright.

This was my first GenIII rebuild, and the FIRST ever supercharger in the forums anywhere to have a A+ show quality polish job on it. This is what it looked like 3 years after running it when I removed it to install a GenV.




Inlet was bored to 75.5mm to match the LS1 TB.


My unique outlet I did on a Bridgeport as well.
