Like Mom calling you home for dinner when you are half way up the tallest tree in the forest...except there is a bear behind you with [insert auto manufacturer emblem here.] "Mom! You just don't understand!" Get to the right.

Been researching, and tinkering with gear ratios, but mostly for my own understanding. I have been looking at the C&D gearing matrix in this post. Can anyone comment if there is anything that is incorrect?

If all is correct, then the Porsche 997 TT has a much more challenging time with higher speeds in terms of acceleration which would match my statement. Almost like Porsche engineers wanted only low end, mid-range, great start acceleration, and then as an afterthought for drivability they worked out expected top speed and geared it that way...not exactly the most efficient use of HP, but likely MORE than OK for track usage. Just leaves them exposed on the Autobahn where speeds exceed 200. The C4S yesterday was not fooling around, and he was damn fast. He let me have the lead with plenty of space after a couple of acceleration runs where I out shifted and out ran them...and I get to watch the conversation in my rear view mirror between him and his wife.

But of course, do not believe me (I am a troll or a little girl or whatever.) I am likely a liar.

Just look at the gear ratios. Substantial differences in the higher gears.

I will spare you the excel sheet I am tinkering with.

If you are considering a Porsche for the track, this post is likely irrelevant to you.
I am not going to mod mine. I have zero experience in this category (one of the reasons I was interested in this forum - that and the USB thing), so I would love to hear other opinions. Guess that would be in tuning?

I have another story about a 4S that I will just not talk about since this post went so well (not.)

I did discover that the extended electronic limitation that is supposed to kick in at 270 - did not...I hit an indicated 300 today, and it was still pulling. Mech at the shop says it will do 330 unlocked (indicated speed.) Glad I paid for that option.
The e92 M3 has a 60hp advantage on the C4S. 414hp for the M3 and 355 for C4S. And the 997tt is 480hp. I would think that the M3 should have an advantage against the C4S, but will get blown away by the 997tt all the time. I don't understand why you're not getting this. And you're telling me you actually did 186mph on your M3! I didn't know they can go that fast with the rev-limiter off.
