[s-cars] Rear-mounted Squires Turbo System - good for S-cars?

[Aaron]

Thanks Mark,

On their web site they make it sound like the distance from the engine 
contributes to the intake running cooler and not requiring an 
intercooler.  I suspect its just the low boost levels or perhaps the air 
is somewhat cooled along its path back to the engine.
