I am waiting on my New Radix to arrive and want a way to be able to turn off the boost ...for like when my wife drives or when I leave my truck at the detail shop...preforably from in the cab...but if I have to I'll pull a vacuum line or something...any ideas on how to take away the power when necessary?
Thanks,
Damon

 

So you want a switch like the one in Mad Max, right? Like where he's running down the road and wants some more power and he turns on the blower?


It doesn't work like that.


But you could do a very low timing program and load it up in the truck before you hand off the keys.

 

It has been to long to remember Mad Max...but isn't there a vacuum line I could cap off or something so when my wife drives she don't know it is there...or so my detail guy can't joyriding?...otherwise it would always be "on".

 

I believe mercedes had a clutched blower a few years ago

 

yep:

The supercharger engages on an as-needed basis to reduce parasitic losses and save gas when less power is called for. Air flows right through the scroll-type compressor, so no bypass is needed. The clutch is a conventional air-conditioning compressor clutch. It is not necessary for C32 and SLK32 drivers to flick a switch to spool up the blower because a computer does that for them. The engagement is undetectable from the driver's seat. The compressor is driven off the engine's serpentine belt, which would snap if the supercharger's clutch suddenly engaged at high rpm, so the computer is programmed only to do so when the engine is below 3000 rpm.

 

I wouldnt do it when my wife drives it but tape a small block of wood under the the gas petal so they cant floor but can still drive it.

 

I'm glad the Radix doesn't work like that mercedes one. If it did that clutch would be the weak link in the system (sort of like the oil pump in a rear mount turbo...). Not to mention... who doesn't want to be able to engage the supercharger at 3000 rpm and above? You never know when you might be cruising at 3k and need a little more. If you had to slow down to get it to engage you've already lost the highway race

 

I've never seen a Radix before, but from my understanding of it, it has a vacuum operated bypass valve that bypasses air around the blower for part throttle operation. I would think you could put a solenoid operated valve in that vacuum line to lock it open and use a switch in the truck to operate it. I believe the truck would have to be running to switch it to the "off" boost mode, because it would need vacuum to hold the bypass open. Just an idea.

 

This might be what your looking for?

I wouldn't want one either, but hey, that's not the point is it.
