anyone ever done / considered a "remote turbo" on their mini? seems like the R53 would be a great candidate; make it a "one ball" exhaust and use that newly made space for turbo placement. since the turbo is NOT in the engine bay, this could potentially clear up the overheating issues that are commonly seen with twin charged setups.

even "cooler" would be to use an exhaust dump valve hooked up to the turbo with active ecu management. This way, you could basically press a button that would open the exhaust dump valve, which would drive the turbo, enabling a twin charged system. at the same time, the computer map is adjusted for the extra power, enabling full turbo use.

yes, its over complicated, but think of me as the "Rube Goldberg" of engines lol jk.

Thoughts? Never heard of a "remote turbo"? its a neat idea. Google it, and check the Images link!

 

Ive seen them done a whole bunch on older Fbodys and the like. I never understood them. Seemed like there was so much piping it wasnt worth it. I always wondered how bad the lag was, or how efficient that kind of setup really is on a street car.

 

well, you Dont need a turbo manifold for one, you may not even need an intercoler for 2 (since the pipe to the throttle is so long and the turbo gets so much air, it cools it quite efficiently), its much easier to install one where you have a ton of room (back underside of the car) for 3.

lag, probably, bad, prolly not, as it should be a pressurized system anyway. efficient, why not? how is it any different than putting the turbo under the hood?

piping, well, its Longer, but not More complicated per say... may be even Less complicated, since you can bring the pipe up from where ever you want under the engine.

 

Moving the turbo back does not solve any of the issues with twincharging, it probably just complicates the setup even more.

The problem with heat on TC setups stems from the fact you are running two FI sources, doesn't matter where you put them. You are cramming heated compressed air from the turbo into the supercharger where it is compressed and heated even more.

Twincharging was THE thing in the MINI world back in circa-2006...but I can tell you, there is a reason you don't see them anymore. For big power...you go Turbo-only or Rotrex, pick your poison. And FWIW, some M45 cars now are making as much if not more power than some of the old twincharged cars were making back in the day.

That's the thing, they aren't efficient, its too much distance for the boost to travel. They are cool for show, or if you really want to turbo something that has ZERO space up front...I've seen someone try to do E60 M5's with it and as far as I know, it never panned out. Tuning rear setups is a nightmare.

 

Eric @ Helix has a T/C setup with the turbo in the rear right now, was @ the dragon with it this year.
