This is not "spirited" driving, but just commuting? The CS has an optional performance package which would have an auxiliary transmission cooler. Does your car have the optional performance package?

On track, there are times when you are riding down the brakes hard from a very high speed to a very slow turn, and the transmission will start downshifting a bunch of times, each time sounding like a double clutch downshift as the engine bumps the throttle enough each time to keep the engine...

Exactly. And I bet Racer57 agrees. On the other hand, if I put 93 octane in my 8:1 compression 350 small block from 1974, I am not going to get any more horsepower, so Racer57 is also correct that octane, all by itself, does not add horsepower. I am just saying no need to fight about it...

Well, I am not going to pretend to answer for anybody else, but yes, for me. Using the paddles kind of sucks, because there is this lengthy delay. You click it and wait and then it shifts. Just leaving it in D in track mode keeps the rpms up. With 10 gears, that is a lot to try to keep...

I did not use my paddles, but let the transmission shift itself. I experienced no problems like this.

The advanced timing and higher boost pressures mean more horsepower. You are being pedantic. I think you are on the same page with us if you stop to think about it. If you look back, you will also see that nobody, not one post, made the claim that higher octane gasoline makes more horsepower...

It appears that this is not what he was referring to. His car was actually malfunctioning. So this and all of the one throttle body closing and other theories are not what was going on. Some sort of camshaft issue - hopefully we get some more detail about what was going wrong with the camshaft.

Fixed under warranty?

Nothing like that available here in Georgia, to your north.

I could swear I hear the little springs sound of light pinging when at low rpm and adding load, but not enough for the transmission to downshift . . . and this is on 93.

The Dodge Charger RT in the article is 10.5 to 1. So I want to ask a question. What if you use 87 octane in your 12:1 compression Mustang GT religiously and drive it hard even on hot summer days? I have to think that there must be some sort of longevity issue that will arise at some point...

The F150 is interesting. So using 87 octane lowers the boost down to 16.2 psi. Imagine if I said I was going to build an engine for boost and run 87 octane and force 16.2 psi into the cylinder with turbos. Would you tell me I am crazy? The F150 pickup did lose add a second and lose 4 mph...

And lol at the BMW making 617 to the wheels on 93 when that is what BMW says is the flywheel number. No wonder those cars can accelerate so quickly. But, no, they did not risk putting 87 octane in this car. Whew! You can pick these cars up now with less than 50k miles for about $55k

Imagine 18.5 psi forced induction but only getting a total of 190 hp and 179 lb ft of torque!

krisk, For what it is worth I was quoting a post about the other system coming loose, not the rear camber arm.

Which camber plates did you install?

You say "best," but do you need/want more than that? I guess I assumed that even at -2° you are starting to hamper the ability to apply throttle early coming off the turns in that 500 horsepower beast. Wouldn't that problem just get worse the further you go?

Looks small. I guess I was just more concerned about what a 20 pound chunk of metal would do in a collision (which is also lighter than I thought it might be).
