Not sure what the point would be. Wouldn't the exhaust gases be moving faster right after the manifold, since the pipes are usually smaller than at the tailpipe? IIRC, between a smaller cross-sectional area and a larger cross-sectional area, the same volume of gas will move faster in the smaller area. Therefore, why would you want the turbo back there. There would be much more turbo lag, and the air would have to go so much farther to get to the intake, invariably having to go through dozens of angles and bends. This will also slow that air down. Further, what happens when you go through a puddle and end up like Sarah, with a $3K turbo and an intake manifold full of water?
Not saying it's the worst idea in the world, I just think that the amount of work and material that has to go into it is totally overkill...not to mention that if they're plumbing the compressed air (post turbo) through the trans tunnel, it's going to get hot from the surrounding pipes and mechanisms (rear end, trans, etc.). Also, if they have an intercooler up front, the change in temp is going to further slow the air down. When the temp drops, the pressure will drop (as will boost), because of 1- the loss in energy due to heat and 2- the fact that cool gases take up less space than hot gases. Didn't these people think of all this?
I don't know...what does everyone else think?
