I'm not sure the BMW v12 is strong enough to take much boost anyway. If it was it would have had more publicity surely?
Actually it can and does take a good deal of boost (I believe 15psi on stock internals IIRC) and it is a popular engine to use FI on (normally a twin turbo setup).
However I only have the one turbo (GT4088R) and pipe work will be relatively cheap for me (compared to buying another turbo) I don't think I would mount it quite like STS does right at the back. I am contemplating mounting the entire engine 100mm-120mm back in the car (I know this requires alot of work) and mounting the turbo in front of the engine block that way the exhaust only has to travel about 6" more than it normally would with a normal turbo manifold. With proper insulation wrapped around the manifolds the exhaust shouldn't be any colder by the time it gets to the turbine (probably be hotter then normal).
I will need to think about the whole plan some more.
Next question: Has anyone heard of modifying a cars existing AC system to work as an IC? Seems to me that it would work quite well being a refridgeration type cooler. Does anyone have any ideas on how to make a working system (thing to think about?).
Power, whether measured as HP, PS, or KW is what accelerates cars and gets it up to top speed. Power also determines how far you take a wall when you hit it
Engine torque is an illusion.
