Turbos : Front mount vs. Rear mount pros and cons
Any experiences or opinions would be appreciated, the obvious is heat and weight distribution favor rear mount, spoolup is supposed to be better with a frontmount....enlighten me !!

It is less efficient. However if pure performance isnt the prmary consideration, the advantge for a daily driver is the better cooling and less underhood temps.

front mount all the way. The closer you keep the turbos to the exh heat energy the faster they spool.
STS and the rear mount guys do tremendous work and rear mounts will "get you there" but not as efficiently as front mount.
Look at Audi and the Mercs they tuck the turbos inside the intake valley and run the exhaust outside and spool those tiny turbos to make instant torq.
Rear mounts will always be playing a bit of "catch up" in terms of overall efficiency but if you are willing to live with the trade offs they work and do indeed sound awesome unmuffed.

It would be nice to quantify it. I wonder if anyone has ever taken a single turbo engine, run it on a engine dyno, then extended the turbo and piping 15 feet and then retested?

I doubt that, but a corvette exhaust routing is pretty short compared to some cars. A lot would depend on piping size, heat wrap, cubes and maximum expected output of the system.

Spool, transient response etc etc.
But it would certainly be a very interesting and relatively easy test to carry out.
