3800 SC - Trying to squeeze out a few more HP (Page 3/3) Blacktree FEB 04, 09:55 AM If it's not a daily driver, then definitely gear it up. That will pay dividends at the track. Also, you can make a Gen3 blower behave more like a Gen5 with some port work. This is assuming you don't have access to a Gen5. If you can get a Gen5 and port it, that would be optimal.

Right on - I actually am half way done porting my G3 M90 right now. I also have a brand new G3 M90 on standby that I got a deal on about 9 years ago. That having been said, I am curious to see what the porting work translates to at the track. I may do a gen 5 as a future winter upgrade - who knows.... olejoedad FEB 04, 12:03 PM If your goal is personal best ET, your best returns may be found in the transmission, suspension and tires.

Porting the input side is pretty straightforward... just open it up. That should improve the efficiency of the blower. I am working on this part right now - finding it harder than the outlet.
