Radix or STS for a 408?
If you were to build a 408 (hypothetically), which boost would you prefer - Radix, or STS - and why?
|
I would do sts out of those 2. You have more room to grow with the turbo choices. I believe you would max the radix out quick on a 408. You could get the gt70 kit and run some good boost on the 408.
|
Radix, of course.
|
Turbo for sure. Like Beeftip said GT70 or 76
|
Thanks, guys, for you input thus far.
If you would, when you reply, please give the reasoning behind your recommendation. I'd really like to see what's behind your thinking. :thumb: |

just put a procharger. make it easy on your self :) |
I don't believe a Radix can support the CFM needed to make it worthwhile on a 408. The STS could easily do so with the upgraded piping and bigger turbo. One good aspect is the lag won't be so noticable on the big motor due to the great low end power.
So out of those I would definately go STS. Another factor is where you want the power. IMO a roots style would be a waste on a big cubed motor because traction will be limited. Why not make the motor more efficient in the midrange and top end instead. |
Kevin you need to go turbo if you want that big of a motor. On top of that, a turbo kit will cost less then an equivalant supercharger that can support the 408.
Besides, it's damn nice to be able to adjust boost in the cabin, and you can really get into the tuning to have low boost low octane maps, and high boost race maps, and econo maps. If you do decide on the STS route, or another flavor of Turbo, I may take that Radix off your hands. My condo sale is coming up and I'll have some cash hopefully. Forget my wedding, I have priorities. :devil: |

If Kevin really wanted to, I bet he could get that AV to hook like no other. 3. I bet that STS would pull like a freight train at freeway speeds and he does drive the highways quite a bit. (did I just say something nice about the gutter turbos? :twak: ........ok I'm back :angel: ) |
