I do not think the 08 Gs will be hitting 550s....So far, the most cost efficient way of raising the HP output on this na motor is to replace the breathing system and recalibrating or remapping the ecu, which are both environmental UNfriendly. Such environment conscious US market (sarcastically) is the biggest market for Lambo spa thus, I hardly doubt the techs at santagata will let their vehicle breathe better. other than such simple way of raising the output, the only way to na tune the car is to rebuild the motor with reinforced, lighter cams, valves, head, cylinder coating to sustain increased compression ratio. I feel the motor already has high compression ratio with very high redline considering its displacement. Unlike the other comparable v10 motors, the strokes are not short and the combustion chambers are quite square(not over squared). Such modifications on low volume production motor are not efficient in terms of cost vs conc; at least in my opinion. I think the change in gear ratio has been enough to compensate the 'slower' acceleration. Upfront, na tuning is much more costly than using forced induction, although i much prefer na tuning due to its revebility and faster dropping of rpm needle. Besides, i think na motors are always more fun than the forced induction tuned motors. IMO, by any means a awd v10 G is no overweight, but weight reduction is probably a better solution than just further increasing the output. A few hp gain will probably only be accessible at high rpm if not on the redline, with not too much change in the whole output curve; IF the increase ever happens, which i hardly doubt.
