It seem the c160 reach lower speed at 7500rpm in each gear. However, I am curious that whether rpm climbs faster due to the 4.529 final gear? If so, can I conclude that, c160 acelerates faster than c52? Let's put the strong/weak thing one side. Just focus on aceleration. 450hp+ seems to be unrealistic to me... Can't imagine how can I make use of that big power.. I would prefer something more practical to drive... let say 200hp? Can c160 manage this hp? It should be real fun to drive with a diff!! Why would you say it's better than cusco? Sorry for many questions. I just want to understand more about this area. by the way, is it possible for put c160 final gear into c52?
