my brother is looking 2 get some hp outta his 5.3L and is looking @ either a powerdyne or vortech supercharger set-up. the price difference is $500 in the powerdyne's favor. but i told him that the vortech is a much better quality supercharger system, @ least from what all i have read and the $500 more will be well worth it.

BUT- the vortech kit comes with bigger injectors and no tune, while the powerdyne comes with bigger fuel pump, and fmu. what do you guys recommend he do. he needs get a tune whether he likes it or not so vortech or powerdyne?

 

I have used a powerdyne with the 9 lb pulley and my 5.3 ran faster with a hundred shot intead of the blower.

 

yeah he does alot of towing and off roading so he wants power all the time. powerdyne sux, i think that is the problem

 

vortech with out a doubt!!

 

Definately.
Im selling mine in the next few weeks with FMIC(as soon as I get it off)
and it would be alot cheaper than retail for either!

 

lol only if you can finance. i got him a job working machinery for $17bucks an hour so how ever long it will take him 2 get how ever much. i will send you a pm. he might need a little longer. (gotta pay off credit cards is what he told me.)

 

go with the vortech kit, mine came with a handlheld superchips tuner btw. up to 11.5 psi on the 6.0!!(thats with the 3.1 pulley ) i have the 2.89 waiting

 

I'm not being BIAS but what about a Procharger. I would highly recommend a Procharger D-1sc and 3 core Intercooler and that would be one bad ride.

 

if he is not in to supercharging it does not matter what kit you pick up, it just will not be right. for less money he can have more fun ( that he is use too ) with a 100 shot of nos and a set of 373 gears.

 

he does alot of off roading. so nitrous isnt really for him + he hates it.
