OMG...that "port job" looks absolutely horrible. Stear clear of that like it's the plague.

It's hard to judge the quality of the porting by that thumbnail picture, but IMO the only port I would even consider would be Stiegemeier's. Proven quality. Proven power. Proven service.

472rwhp for a ported blower isnt very much, If i got a ported blower I would expect around 500 get the Stegy so you know it going to perform!

Hmm, I wonder if its one of those ports that those guys were trying to do for people, but they kept losing power.....I think his name was Soap or something

"Ported Eaton Supercharger off of 2003 Cobra with 4087 miles. Includes 2.8 pulley. Made 472 HP at the tires, have dyno sheets."

Umm... my friend has a steigemeier port and a 2.93 pulley, just intake and exhaust/x-pipe and with the SCT flash it made 502 RWHP. That blower sucks. It also does not look smoothly machined. No wonder the owner took it off and put a KB on it :nono:

I can relate to that claim. I made 504rwhp (2.90 pulley and basic mods) with my early Apten blower (ported by Stiegemeier) and Stiegemeier has optimized the porting to produce even more power. So 472 rwhp with a 2.76 pulley and an unknown port isn't squat IMO.
