I also have a 1500 hd and i have a procharger on it .keep in mind with a procharger u will also need injecters and a tune.prochargers are not a bottom end blower your lookin at about 2500or 3000rpm on other than that I LOVE IT

 

I had a Radix, it made great power! I attached my dyno chart.....

 

I see your engine likes to take a little break every once in a while.

Nice power.

 

I think that a lot of people have said this before, but the Radix is good for daily drivers. Procharger is more for a drag racing setup. I am sure the KB is good too, but I don't beleive they have intercoolers.

 

KB does not have an intercooler yet. If you're good at custom work the KB can be set up very nicely. (they are hard to get a hold of) Rumour is that they are going to come out with a much improved package soon.

The Radix is definitely the most complete kit I've seen.

Good luck in you purchase!

 

I was running a procharger on my 5.3 with 12 lbs of boost before i sold the procharger. I still had stock injectors and just tuning and i made 375 rwhp. it wasnt bad at all for a daily driver. but it seemed to be very inconsistant when i would get on it a lot. It would have been better with a larger intercooler or even upgrading the head unit to a D1. but all in all, i am going to stick with making my power the old fashioned way. all motor and maybe some nitrous for insurance purposes. also, when i used to be procharged, i always told myself that i would be loyal to them, but now after ive owned one, i would say to go with a roots style blower instead. Procharger has excelent customer service, but i just had too many problems with mine.

 

Like I said I have the KB I have 372 RWHP. But the headaches of trying to get a hold of someone at KB is not worth it. Get the Radix or who ever else makes a good sysem. The advantage of KB over the rest is they provide every thing from the tune to the injectors and the intake. If you want simple go with KB but be prepared for all the ******* headaches.
