It can work...I just don't understand why people think they need to run a turbo with a twin screw blower....it's a freakin' positive displacement supercharger...it won't stop making boost on that 2.3 at any rpm...low-end, mid-range, top-end...doesn't matter...sell your turbo and make your car a little lighter...you'll be faster.


About the positive displacement I will be adding a bypass valve eventually so when the bypass valve is open the sc cannot make boost. That will solve that problem and just the turbo will be working. And about making the car ligher well ill post some pics of my car.

I think most turbo/supercharger setup's (designed to work together) bypass the supercharger at high rpm's.  I don't know how they do it.

A bypass valve set at a given boost rating would do it.  Since the blower is feeding the turbo I would think that you can put the bypass valve in between the two.  The trick is to pick a good point where the turbo is starting to make it's own power.  There would most likely be some experimenting involved here.

The only issue now that I need to solve is the belt routing. I also filled the supercharger with oil and now its super smooth. Won't be long before its done.

Something I would do.  Install a boost gauge on that pipe going from the supercharger to the Turbo.  If you started reading vacuum at high Rpm then you would know it was a restriction.  Would be interesting to compare the reading off that pipe and the pipe going to the intake.

Also are you overdriving the supercharger?  On SC's they run at something like 12k rpm because of the jackshaft.

Yes I will be checking with a boost gauge on the sc to turbo pipe that's why I installed a nipple on the pipe.
