I would not trade a 545 for 550. How desperate you are to get a glass of water? can you wait 0.3 sec more to get there

 

One thing is for sure. I can't wait until Car & Driver or Road & Track road test's a 550i. October maybe?

 

I definitely will keep mine for, say, 3 years. Also, I don't like first year cars even if they are BMWs. I have added a B&B exhaust and a Dinan throttle body. Given the weight savings of the B&B, I have added the equivalent of about 20 RWHP (about 24 diluted HP)--which ought to be close to the equal of the 550i's 360 diluted HP. Dinan is supposed to have a cold air intake, programming, and maybe a MAF out at the end of Sept. (we'll see). I plan to do all, but will do at least the intake. I will take the intake and exhaust off when disposing of my car if I can't get enough for it with these items on. I don't expect the 550i to be more than .3 secs. faster in the 1/4 regardless of what has been said otherwise.

Just curious, how did you calculate that the weight savings of the B&B muffler added the equivalent of 24 HP?

I wish it did. Darn. ~(:^) My calc. was [(8 throttle body + 10 B& / .85] + 3 HP ( 30 lb weight savings of B& = 24. One also can add about 4 HP simply by removing the spare tire and jack while driving in the city (weighs almost 40 pounds)--giving a 27 HP gain. A saving of 10 pounds equates to about 1 advertized HP--which can be shown by playing with LB / HP ratios. You have a beautiful car, but see my sig. ~(;^)

Also one saves about 10 pounds per wheel going with light aftermarket wheels and non-runflat tires. I think this would be even more effective than 40 pounds on the chassis because it's rotational energy involved here.

 

Not me.

What "huge" performance jump? 0.3 sec. improvement 0 - 60 MPH according to BMW.

Not to play semantics, but as i said "some" have stated the 550i will have a sub 5 second 0 to 60mph time, .5 second improvement in the 1/4 mile meaning a 108+mph trap speed and at least a .5 second improvement in 0 to 100mph times.

I guess we'll see when the 1st 550i's reach our shores.

Of course there's always someone else faster on the road but i'd rather be one of them.

Those are the numbers I would bet on. Some carmags will not do as well, but that's what the best test results will be.

 

Whats the hurry? Cant imagine that big of a difference to go through a new set of acquisition costs. Plus the performance of my 545i is plenty sufficient...for now.

 

Thats right... "for now"

[/quote]Yes, check out the current thread on lighter after-market wheels.

 

Nope. My 325HP gets me to work on time.

 

I won't change at 7K. It's just pissing away money until yr 2-3 of ownership.

 

Evenflow, that's great. Though in some parts of Little Rock I'm sure the residents are certain they see Martians every day!

If I get another e60 it will be an M5, and then only if I hit the lottery (or analogous circumstances). Wolverine will gladly tell you Michigan grads always do better $$wise than Buckeyes, and that's why he can get his M5. I'm jealous of his car; not jealous of his football team.
