Can anyone tell my why Vauxhall fit their engines in back to front?
I'd like to know why fitting the exhaust at the front of the car and have it trail underneath the engine benefits from having the inlet at the front where the air is cooler then having a shorter straighter exhaust from the back.
I would rather lose by a mile because i built my own car, than win by an inch because someone else built it for me.

Bulkhead further forward for more room in the car?
Engine further back for better COG?
Not sure. Agree it's a slightly strange idea.

i would guess it derives from rwd where the intake was on the drivers side, if you spin the engine round it for fwd application it puts the inlet on the back of the engine. its not just vauxhall that do it, look at most pre 2000 cars, they are all the same.

Ford, Volkswagen, Nissan, everyone does it.
Inlet only works better at the front if it's open, if it's a plenum it won't matter so much.
Longer manifold length and more bends = more torque?
