ok, i have a 06 with the 4.7. I love the motor but im kindofa speed guy. I know someone knows the best supercharger out there for these little motors. I read somewhere of 350hp and 400tq but newais. Any help is appreciative!!!!!

 

www.krcperformance.com has one out for our trucks. 5500.00.

 

i personally would try the paxton but im going a different route.......
try krc... if ur really committed keep us posted if your doing it or not.......

 

if you are serious about supercharging a 4.7
you should be serious about changing the stock pistons
which from the factory have
small 'ring land distance' above the top ring groove
and the weakest one of your eight pistons
will fail under supercharged boost
unless without fail
a high octane fuel is used like E85 all the time

 

Hank, shouldn't you also go with a forged crank and ported heads?
