I was looking around at parts for another vehicle, and came aross this site that offers Eaton SC porting for various Mustangs. They just so happen to do LSJ Eaton porting.

Cobalt SS

Apparenlty they claim that they got a 30+ HP increase with just a ported SC and throttle body, the dyno they posted shows a 36 HP and an 11 ft lb torque increase. I think someone has been tricking the dyno IMO, because I don't see that kind of power happening on just a ported Eaton and TB alone. I could be wrong, and I hope, because if that kind of power increase can be had for $375 then sign me up.

Anymore it seems that no one fools with homemade dremel porting to the SC inlet that people used to do back in the day on the LSJs. I don't think I recall seeing anyone having them professional ported. Is there really anything to gain from porting the SC?

 

There's no way for that to increase 30hp. As far I know of to port Your supercharger to increase at least 10hp. 30hp!? If smaller pulley with LS4tb then maybe but will be close!

 

30 crank hp is believable.. Search around. The right port will net some decent gains
