I'v been researching a little bit, and both me and my brother are thinking about buying some magnachargers, i have a 08 rcsb 5.3 3:73 he has a 08 rcsb 4.8 3:08. Would we be ok w/ just the 112? or should we get the newer ones that are coming out, i dont wanna drop 5g's and 2 weeks later come out way better, Also what kinda boost can a basically stock 5.3 take?? can we upgrade pullies like i use to on my lightnings?? what kinda power???

 

ttt bump

 

Yes!
Go with the TVS units if you want the newest badest ****'s on the market. The 112's are just fine too and maybe had a little cheaper but not sure about fitment for your new trucks.
As far as the engine goes, it'll take a licking and keep on ticking and yes you change pulleys (and tune) for more boost.

 

^^^^Yep listen to what the Man said. ^^^^

 

Im happy with my 112 on my 08 4.8 runs 5-6psi stock out the box http://www.youtube.com/watch?v=6Y4EdoXGxGQ

 

seemed like it would barely get the tires spinning until it got into some boost... guess thats the 4.8L tho... your truck looks DAMN GOOD Chev...

I just did mine and I am very happy with it and the output it has given.
Well worth it. I will be doing another one very soon that belongs to my boss.
He was amazed at how much of a gain it made.
