Conventional turbocharging is done from the manifolds. Or as close to as possible. In the last few years, a company (STSturbo) came out that designed a system for rear mounted turbos, that seems to work well. What I am ultimately trying to figure out is the most efficient way of turbocharging a gasoline engine. I came up with this idea. Normal pulse matched headers, going into a y exhaust setup (say 3 1/2") running to the back of the car, mking a u turn, then up to the front, where the turbo is mounted sideways (So the compressor inlet faces grille) Now plumb compressor straight into intercooler. Dump turbine exhaust behind front tire. Compressor inlet has filter on it poking into grille. REASONING. 1. Exhaust temps to turbo would be at atmospheric temp or close to. (Denser, pulse matched and you would not lose velocity, you would gain because of size of piping used?) 2. Turbo would run 2x as cool as a conventional or rear mount. 3. Oiling is easier to plumb. 4. Turbine exhaust has little to no backpressure. This setup should make more power than either setup. (Traditional or rear mount) Questions I have are... 1. Must the turbo have the heat element in it to function optimally? 2. Would you need to have a smaller turbine housing with cool air pushing the turbine? or would a larger turbine housing work the same? 3. Out of the 3 setups mentioned which would produce the greater amount of compressed air (boost) This is more for a personal project than anything. So any insight would be appreciated.
