Remote mount turbo?

Dollar for dollar it's going to be more effective to go with a "reg". That's not to say one shouldn't do a remote mount, maybe some one wants to make it appear as a sleeper and run a completely different setup (mid placed turbo, hidden intercooler, etc). I know people personally that have done remote mount turbo setups on C5's and had great results. That's not to say that it was effective. Just imagine if they would have been willing to cut the inner fenders to fit a turbo in the engine bay? What's going to be more effective? Now the C5 != S4/5 and so they'd spend more money altering their engine bay to fit the turbos which means for them it would be cheaper to do a remote mount.

As far as this particular facet of the debate goes:

The C5 around here running this setup puts out a little over 580whp at 6psi. Up from its previous 390-410 in with various exhaust setups (engine also had other mods). Now, if you were to put a traditional set of turbos in the engine bay, maybe it would make 600-610 at 6psi? Hard to say, but the difference is very negliable make no mistake about it. Its not like running a turbo in the rear automatically means its 50% less efficent. Either setup would be VERY comparable when you omit the install/fab headaches of doing a rear mount turbo. Shit, Randy even has EMP on his setup and 6psi of MAP there's only 6.75psi EMP which is an extremely close ratio (edit: yes clsoe ratio for "low" boost, but nonetheless.)
