under body turbo
I would think the boost profile would be terrible due to the very large effective throttle volume from all the post compressor piping
The only real bad thing I see is the filter location.
Right behind the rear tire.
Those filters would need to be replace very quickly due to all the dirt back there + if the filters fail to filter properly you would be sucking some major stuff through the compressor.
I would love to see this on an S there is plenty of room in the back after where the factory split is (assuming removal of the resonator for greater flow.
Also there is plenty of room in the middle of the frame rails to run the return pipe forward. Also if there was enough room to run a RWR inline A/W Aftercooler where the return piping is the system would truly be stealthy.

The throttle lag would be HORRENDOUS with this setup.
Scorpion, although the cooler exhaust gasses would have more density, their velocoity would also have decreased compared to the upstream flow. The overall mass flow rate would remain constant throughout the system. I see no reason to believe the website's claim that the cooler air spins the turbo more efficiently. Also, the dominant factor in intake charge temperature rise is compression, not turbo heat.
It would be interesting to see a turbo setup that placed the turbine immediately after the stock header, in place of the catcon. The stock header is already very efficient and I'm sure it would yield a higher bost/psi ratio than a log or a shorty like InlinePro's. The length of charge piping wouldn't increase greatly compared to most kits on the market either.

I believe turbo magazine ran an article a couple months ago on a rear mounted turbo, think it was for the tundra, and the way that the company had set it up, there was relatively little boost lag.
Yea my friend has the sts kit on his gto. We went out for a ride, wow, its sick fast. We got back, he popped his hood, and i put my hand on his intake plane, very very cold. Its an awsome set up. Hes putting somewhere like 500-600rwhp at 9lbs, and 500-600lb/ft. Its pretty impressive.
the whole idea just seems like way more work and with the charge piping that long there has to be a huge boost lag and u increase the chance for boost leake by 100 times, plus if u ever bottom out ur setup is done, love to see how much a shop would chage for install compared to a normal turbo set up
I've heard a lot of speculative negative comments about these rear mounted setups, but results speak for themselves. At least for large V8 engines. It works, and it works well. There may be a C6 in my future, and for sure it will have this system on it.
My ideal RTS would be
twin turbo setup initial power(6.5psi 310whp and 210-230Wtq)
(two disco potatoes GT2860RS with modified trim to lower spool up time, E-manage ultimate piggy back with water injection and/or PWR A/W intercooler)
There is plenty of room in the back if the factory muflers are removed.
Later going to higher boost with engine modifications and seeing if an ITB setup can be intergrated with the turbos
If you check out the Vids form STS there is an intergra in the works.
Some of the setups sound like the turbo is allready spooled when at idle!!!!!
