Its correct that more gears favour acceleration which means that a vehical with 6 gears will be more responsive when shifted when compared to the one with 5 gears.
That is why new bimmers are comming with 8 gears instead of 6/7 to make them more wild.
BTW this engine produces 165PS. I wonder what will you do with that much amount of power. And you'll have to install CNG as it is 20 Valve which means less fuel efficient then our normal 16 valve cars.
