What ever happened to the one George M built with the carbon air box?
Last thing I saw it was running but needed some setting up on the Dyno.

The car George did is up and running, and is very strong top end with around 165lb/ft torque at the wheels, this may well increase with further tuning.
It is about the only ZS (with std ratios) I know of, that can accelerate through 5th gear, G said 152mph top speed, not having seen it do 152, I can not confirm, but it is a different animal to a std ZS.
That was simply an intake/plenum, and used a 1.8 small throttle body, proving that power is not necessarily found in size of, or throttle bodies, but rather design of the intake trumpets from plenum and volume of plenum along with venturi design and bellmouths.

George would be the man, or steve who owns it, I think the car has 270cams and some cat back exhaust, but it made 25whp+ with the only difference being the inlet plenum, so yes, it appears that just that mod is worth 25-30bhp alone!
