I was running 7 in the STS kit and about the same in the Radix. Well it depends on what you want. I feel the Radix is more reliable and less prone to a disaster like loss of all engine oil. The STS kit I think has more potential power for less money. My opinion is that I like the Radix better.

 

i thought the STS kit had a remote oil system to prevent the oil loss disaster? maybe i was reading someone who did that. who knows. whats the max psi you can run the STS? is it possible to go up to like 18psi like the livernois kits

 

I think it all depends on the turbo you get with it.

 

They also have an alarm, if there is a problem with the sts oil pump the alarm in the cab will go off. I haven't had any problems with my STS oil system for over a year now.

 

Actually my supercharger you feel right off the bat. As soon as you stomp on the gas she throws you in the seat pretty hard. I wish I knew everything my Escalade has but I don't. I just bought it and it already had a Magnacharger, Headers, exhaust, and I presume a chip. But I dunno. On a G-tech I ran 0-60 5.95 and 1/4m at 14.47. But spun all 4 wheels right from start.

 

i have also heard that those g-tech things arent too reliable but still sounds like a pretty sweet slade

 

Welcome to the site!
Sounds like on bad azz Escalade

 

Now imagine going anywhere from 10-30 mph and feeling it hit just as hard or harder. That is what a turbo feels like. Having switched from a roots to a turbo, I have experienced both. They are both a blast, but feel completely different.

 

so is it safe for me to assume silverado that you like the turbo better?

 

i've had both as well...like he says the turbo picks up power at 3000ish and the radix picks it up right from the hit of the throttle...to me the radix is more reliable as a daily driver in my world...may not be in someone else's.if i never had to get off road then i would have prolly stayed with the sts system because it would have been fine for me at that point.they are both great kits!!!
i am building a rcsb stroked 6.0 with turbo right now for playing so you can see i still have the turbo bug in me
