The advantage of more displacement on a boosted engine means you can run less boost and obtain the same power levels. Lower boost levels make fore a safer and easier to tune vehicle. A factory box stock car running 15PSI is pretty insane but the GT500 is all forged....that helps too.
I'm sure Magnacharger and Whipple will have upgrades available shortly have the ZL1 hits the market.

YES SIR.. the 1.9 will start to struggle... and run out of steam and start to just make heat way before the 2.3.... thats why my friends cobra did not like the 18psi.. it was all heat...
