No worries, Mike. You asked a question about changing gears and I didn't want to make any assumptions about what you wanted to achieve. That's where my question came from.
I literally can offer you a dozen alternative 2nd gear ratios, and an even greater number for 3rd and 4th. You see maybe half a dozen "stacks" thrown around here as popular but there are many more options than are usually discussed. I recently spent several weeks working with a guy who has a low boost 3.4l in his Carrera. He doesn't track it at all, but wants the car to be a rocket ship to 100mph. Then he wants to cruise down the highway at 85 mph in 5th gear with his engine at 2500rpm. We went back and forth on the merits of a new mainshaft, what he would compromise with a 100mph 4th versus a 110mph 4th, and many different ways to get to that goal.
That's a very unique stack and not something you see in the usual popular "race" or "3.6l conversion" stacks that people talk about. What I am getting at is I am here to help, even if thats to tell you that what you've got right now is pretty good for you. I'll give you advice that's specific to you and not just something generic. I just need you to let me get to know you first so my input means something to you.
