Here we go again. If the G3 is 50 light, the G2 is at least 50 heavy - not the 10 requested. The math does not add up, because some unknown point of data convinced the ITAC that the G2 gains 30% (or was that 27%?), yet the G3 is processed at 25%. It has the same compression ratio, longer stroke, larger bore, cross flow head with thinner valve stems that flows better than the counter flow head/valves on the G2, and uses a better flowing MAF. Now the process does not take those items into account, only a documented higher power output. The G3 is capable of the same or higher gains than the G2, but I predict that data will never be made available to the ITAC.

The cars have literally identical chassis designs, albeit the G3 has a wider track and larger brakes. If you consider the cars equivalent and assume that the power gain is the only differentiator you see that the current G3 specification must assume a 22% power gain. So something does not jive in how these cars were 'processed' at approximately the same point in time.
