Again, my position is, there is no way the twin screw SC can build off idle boost faster than a Radix due to the fact that it must first overcome its greatest negative to then build boost, however, once it starts to build boost it is more efficient at it. The radix, however, is a cheetah waiting to explode into a full sprint, so to speak, it is 1 step away from productive boost, while the twin screw is 2 steps. Now, can the twin screw really boost faster off idle? I say no.
Do you have your Radix on yet?

Hey all, new here. Have an 02 Avalanche and have been looking at both kits for quite some time for added power (not looking at going to the track or anything). There is great info on this thread. What about exposure to the elements? From the pictures I have seen if you are ever off paved streets I would think an SC or some other turbo option other than the STS would be the way to go, right?

For serious offroading with lots of mud and or boulders then yes. I would say the SC route would be safer. I'll still take mine off road to hit those hard to reach fishing spots and such but for playing around offroad i wouldn't really feel comfortable with the STS kit. Just depends on what you wanna do with your truck

Something to consider in regards to off idle boost. While idleing the quantity of air flow entering the screw compressor will be of such a minute quantity there probably won't be much of any heat build up issues. With that scenario there just won't be much air to compress, especially when the bypass valve is factored in. Then there is air delivery and the distance it has to travel. The roots paddles the air around the outside of the rotors, while the screw sends it down the middle. Each, if they are the same displacement, will deliver the same quantity of air with each revolution of the rotors. What I would like to know is if each would require the same number of rotor revolutions to build like boost. I would assume the screw would have an easier time of building boost due to actually compressing the air.
