[QUOTE="Surfergeek, post: 13436341, member: 140984"] So an update ... Have done several track events with the 3.08s installed and the factory FRPP 624HP tune. Next step is a CAI and Tune try to get close to the 600whp target on 91 octane. Gone are some of the concerns about mileage because it's no longer my daily driver ... yay! It's all part of a learning experience and knowing what different things will do. I don't regret doing the 3.08s at all and if I put in 3.31 or 3.55 and decide to change again, that's a part of the process. You'll never how it works for you until you try it. Some thoughts on the 3.08s Easy to get on it coming out of corners on the track, much better than with the 3.73s and the blower. Cruising on the freeway at speed limit speeds 65-70 the engine is under 2K RPM in 6th and actually not where it seems happiest. The car feels at home around 2,100-2,400 RPM ... Best economy / lowest noise level, most responsiveness. I want a little more responsiveness for daily driving and to cruise at a little higher RPM. I am considering taking the ratio back to a 3.31 or 3.55 ... Probably the 3.31 ... and I think that will be the sweet spot for on track performance and street duties with my power levels. Will see how it drives with the tune. But having had the 3.08s has made it easier to concentrate on learning to drive the car fast, and not have to worry as much about throttle adjustments and managing the power. That comes next and I am ready to give that a shot. [/QUOTE]
