How much HP does a Paxton Super Charger add to the GT 350? 

How much HP would Twin Super Chargers add to the 428 CJ with the 1967 GT 500 Intake?

      The Manufactures have over the decades made claims of 30+%; but speaking in big round numbers, in reality one would probably realize something more along the line of say..............20% +/-.   

      The multiple superchargers one might install on the greater cubic inch engine are more for the volume requirement, and not necessarily find that they would actually produce greater manifold pressure, as that over the S.B. with just one supercharger, so the generally the rule of thumb gain remains relatively constant,  more or less.

I would say a lot less than that

But got to say they made their heaters work better by generating all that lost horsepower

I seriously looked into running twin Paxtons on my car. Cobra automotive had the Paxtons , custom engine plate, and related hardware. To say they were expensive would be an understatement, and the gain was just not worth it. Sure it would have the wow factor but not the go factor, the goal was to run the vintage parts like they might have back in the day!
