Been re-searching this & seem to get conflicting answers, Would a straight through system (best free flowing system)give the best results for a Turbo Car,
I.e
Lower charge temPs
Less chance of det
More Power
More torque
More Low down Grunt (thought this is where back pressure would help ?)
Thanks

You want zero back pressure after the Turbo!

So! bigger, straighter, and just a backbox

Yup, you want no backpressure.
If there is backpressure, you may get boost up earlier, but this doesn't mean more power in any way whatsoever - it simple means that the system is more bunged up. When you read the other notes, just remember that boost is simply a measurement of air that can't be processed yet
