If you want ease of installation and OEM-like reliability, hands down the Magnacharger will be your best bet. If you don't mind a little more of the DIY setup, look at kbracing96's hot side turbo kits. He has introductory pricing going on right now that is a damn good deal for turbo hot parts. You can piece a really nice turbo kit together for a lot less than almost any other FI kit available if you're willing to do a little bit of the work on your own.

[QUOTE=pj4553;3898701] but, For now I need something reliable for everyday duty. I'm going to get an out of the box FI kit (magnacharger or STS) and a stall. My goal is to be able to make enough power to push the truck into 13's. I'm really leaning toward the Magnacharger because of the ease of the install and completeness of the kit. My question would be is my goal of 13's attainable with my current mods + the Radix and stall? QUOTE]

Everyday reliability/ completeness is why I lean toward a Maggie(for me), therefore that is what I plan to use first. I want to 1 day do a turbo, who knows if I'll swap from Radix to Turbo. I'll tell ya if a Radix meets my goal, I'll leave it. No matter which, it's going to lead to other stuff ($$$). Everyone may disagree on how to make power, but will agree upgrades lead to more!!!
I like to know who just put a Radix on & ran a before/ after ET test. Not added other stuff( sorry Trever). I may start a thread to ask that.

 

My truck bone stock ran 16.43, and I think it was 85 mph. With the addition of the Radix and NOTHING else (I was even still running the stock cat-back) ran a 14.38 @ 95. This was with the 5.3.

 

Or a used Maggie.

Its my understanding from PT comments, a Radix will hit a wall( eventually); turbo will go above the Radix limit. Upgrade as needed, based on parts breakage & goals, $, etc. I think, once a tranny & rear are happy, if I've got traction, I'm going to drive it.< like this.

Slowec makes VERY valid point. If u basically want to throw it in(Radix); like to tweak( turbo). I turn my wrenches, so that is also something for ya to consider. Again, everyone may prefer 1 or the other. I think some of the best advice comes from somebody like Blown Chevy( or others). Brian has done both, he'll tell both sides. Dollar for dollar, new or used, I think $ outlay will be similiar. If a blower, many like a Radix. Me too. If a turbo, my choice is Trick. I say for a supercharger, a Radix is #1 choice. More choices are out there for turbos than there used to be, but Trick will get my $ before anyone else.

 

Thanks Thunder, that's an awesome gain! I try to be fair. For now, I'm living vicariously thru u & others. When I've thrown parts on & validate, I'll say w/o any B.S. what I ran. For now, I wait...a lil longer. It's like if I went to buy a guitar. Play a Strat thru a Fender amp using song "X". Since I want to hear a Gibson thru a Fender amp w/ song "X", to compare, & make my own choice, play that. I know 5# on a Radix vs 5# on a STS should be the similar analogy. Sometimes direct comparisons are hard due to temp., other variables, is it the same vehicle?, bla bla.

 

I'm not afraid to turn a wrench. Especially after working on fbodys which seems like GM designed them as a prank. I can picture the engineers saying "Hey Joe, think they can get a wrench in here? Good, I didn't think so." I have access to a lift and every tool imaginable except a dyno. I have to pay for that. It's a pleasure working on the Silverado thats part of the reason why I came back.

Like I said in my first post I have a pretty fresh complete 6.0 sitting in my garage that I will eventually swap in the truck with a 4L80 once it's paid off. Will I be able to get maximum power out of the 6.0 with the radix or will it run out of breath? I was thinking 10 psi on the stock LQ9.

 

10psi on a 6.0L will be running the Radix pretty ragged. You might get there with the smallest available pulley and an 8 rib setup. Belt slip will be a problem, and your IAT's will be through the roof even with a meth kit.

 

Ok.. hmmm. What would be a healthy amount of boost for a 6.0? I'm just trying to get to around 450 hp.

 

Healthy boost depends on a lot. 10 psi on the higher compression LQ9 is doable IMO, but not with the Radix (high IAT's mixed with high compression is bad news). If you want 10 psi on the 6.0L I'd either go with a larger displacement s/c or a turbo. You'll need a meth kit and definitely a good safe tune as well.
