and alot of good info here. I just don't agree on the "tremendous parasitic load" as stated, I think as far as stock kits that the Radix and Turbo kits are about equal.

[QUOTE=JERRY2500]Well here's my dyno chart on a base kit before i put on the IC, fuel pump and injectors.
NICE!!!!! I love to see that Torque curve... flat as a table top!
As far as parasitic losses got... are we talking about at idle or cruising speed? Or full blown throttle? At 5psi, for example, the turbo will put out more power, and from what I understand, it's because the supercharger has a big loss in power just to move the motor (for a lack of better term). That fact has been beaten to death though.
Do I personally care? No. Again, I'm sure I'd be happy with a Radix setup as well. But from limited supercharger experience... I had 2 Lightnings pushing 13-14psi. Both were around 370hp/480tq. My Denali is at 9psi making 470hp/520tq, through a (ha ha) smaller motor.
One interesting thing to note: most every vehicle that has a turbo added to it will increase gas mileage. Mine, for example, went from averaging 13mpg to now averaging 14.5 (roughly). I do 95% city driving. On the freeway the difference would be even more. My average in the Lightnings was around 11-12mpg. I know I know, "it was factory blower, blah blah blah..."
Now, for $5000, would I get a "base" STS kit for Radix? That's a tough one. I bought my "base" STS kit for $3400, then added injectors, Methanol, bigger Turbo. So for around the same money, I would definitely go with the STS "upgraded" kit. The problem is, I now need a new Trans because it can't handle an extra 200hp and 225tq at all-wheels. If the Radix puts out 120hp at the wheels, I wouldn't need a new trans........
Anyway, just throwing in my .02.

I want a radix cause I love the sound of a blower whining under the hood and the instant boost to get my truck moving. If I had a rcsb I would get a sts kit but my truck weighs alot and I do tow quite a bit. Well not so much since I got my tci converter it doesnt like towing very much so its gone when the engine swap comes for a yank truck thruster. Anybody know who has the best deals on a radix I would rather get it new. PM if you need to.

Turbo's can tow just fine. Durring normal acceleration I can see a couple pounds of boost just pulling away from a stop sign. With a lil more throttle I can sit right at the 5psi limit ofr low boost and not even be at 50% throttle. A lot of people seem to think you have to be at WOT to see boost with a turbo. That's not always how it works, especially when the turbo is sized right.
For heavy towing the same mods will need to be done to any FI setup.. A good intercooler and no I highly doubt the stock Radix unit is up to the task any more than an STS kit is without an IC since they seem to put out about the same IATs and the Radix will heat soak worse.
