Thread: When?

When should one consider porting their supercharger? Are there mods that you should have before you do this? Should you only do it if you gonna run an ic? Also when would changing to a N*TB be of benefit?

there is a difference between porting the outlet and machining it for an intercooler. porting is really only beneficial in the sub 3.0 pullies, but it help (barely). the throttle body will be beneficial at any point so long as the blower inlet is matched in size.

here is a stock m90:




the bar running across is what you machine out so the entire bottom of the blower is exposed to help with an intercooler. to port the outlet you extend the "V" and take out those little cornor pieces. you DO NOT want to change the size or angle of the outlet.


make a little more sense?

A picture should help. Here's the rough start Reptile gave my blower case before he went about doing the fine work:

O now i get what you all are doing. Is there any point in porting the outlet if your not running an ic?

Reduced outlet temps. Removing the bridge section is just for ICs, though. I had the bridge removed for when I go IC in the future.

i removed the h-bar on mine and my LIM is opened up at well. i havent had any negative effects with it. i think it makes me feel good to think im feeding the back cylinders more.

alright thanks guys. i think ill look into possibly getting it done or doing it myself in the near future. prob summer when i have an income again and am home where my car is
