Hey my car is currently making 420rwhp and 408rwtrq via an intercooled Vortech and some nice cool winter air. Prior to installing the SC I installed a Richmond 3.90 gear set. The 3.90's worked wonders with the naturally aspirated 2V but there were some problems. First of all RICHMOND GEARS WHINE....ALOT. I came to live with the constant whining but after installing the supercharger and than intercooler it almost seems like too much gear. I know a set of FRPP 3.55's will be quieter and help my mpg's but what do you think about performance. In the cold weather traction is definitely an issue until 3rd gear. Even in the dry weather with Nitto 555 315's outback I get squirly in boost. What do you think I should do?
