530iii

Hmmm.....maybe i can swing an ED 06 550i this spring or wait for an ED 07 550i in October?


As for "rods" one is ambiguously gay...Rod Stewart?

Don I'm in Canada and even I know that that is the nick name reserved for gay boy A-rod of the Yankees Unless of course there is a new use for the term? haha That name suits him!
Your new name is cool, and apparently you put a lot of thought into it!!!

Oh, I see. Nope, no gay-nod here. I don't follow the details of sports at all unless one of the Phoenix teams or Texas is doing something good. I'm definitely a fair-weather fan--at best.

well you're fortunate enough to have Gretzky in your fair city coaching your team. He is the greatest Canadian who ever lived, and as far as I'm concerned, the greatest athelte who ever lived! He exemplifies class and humility and his records speak for themselves! His Mother just died last week and he only returned to the team last night for a 5-4 win in San Jose!
ps...we're looking forward to kicking your guy's asses again in Turin
You're almost Gretzky-like on this forum Don! I have learned more from you then I thought possible on these cars! Have a good day!
[/quote]Yes, Gretzky is a great athelete/guy. Thank you for the compliment, but you have over stated my case. Still, if you have learned something of value from me, then I am very glad.

Trev550i, thanks for the clarification on Gay-rod. I actually meant definition 2. Below is a link to the "urban dictionary:

http://www.urbandictionary.com/define.php?...od&defid=952531

"Small car (usually japanese) with loud exhaust, spoiler / wing, body kit, "NOS", fruity colors, a "cold air intake system (how useless), and are always extremely weak and very slow (0 - 60 in about five minutes). But for some reason, the driver claims it to be the fastest thing ever. Variation of the phrase "Hot Rod".The fast and the furious had a lot of gay rods.

Billy's purple lowered Honda Civic is the slowest car ever made but he picks up plenty of guys in it because it's a gay rod.

Look at the two fags too curious in the gay rod over there"

There's always somethig new. . . .
[/quote]That's all interesting. No gay-nod here under any definition, but I have zero problem with gay anything--not that anyone invoved in this discussion does.


IMO the 550 will be slightly faster to 60 than the 545,but maybe not as much as we would like.I'll list some reasons why it will only be marginally faster to 60
1-550 will be traction limited due to the extra torque and horsepower.Starts on my 545 are already a problem with traction.

Me too.

2-M1 gear ratio in the steptronic(4.17) is too low for the 545 & 550.It is more suited to the 525 & 530 because of the much lower torque & horsepower figures.Ideally should be about 3.50.

I am not sure about this one, but you may be right. When my car hooks up, the 4.17 feels good.

3-Standard tires for the 550 sport & non sport are the same as on the 545 which is already traction limited.A set of BFG drag radials on both cars would benefit the 550 more because of the higher power ratings.
After 60 mph I believe the 550 would steadily pull away from the 545.

I hope they don't pull away from my 545i at least after the Dinan CAI. The 550's and some others are in my sights. But, darn, you gave my "secret" thought away. If I had it to do over again, then I would not upgrade to 19" wheels since neither BFG's or Nittos are available in 19." I would get 18" BBS wheels, which would be even lighter than my style 101's, and would have BFG's on my car at least some of the time. Actually, I am thinking of selling my 101's/PS2's if my warranty-replaced new PS2's don't hook up better than my old ones. Then, ....

Probably should have qualified my statement on the 4.17 M1.I was speaking from personal experience with my stock wheels and tires.With better tires(drag radials) I am sure the 4.17 is better.I think the ideal start would be with light torque braking,mash throttle to floor and get a slight hazing of the tires.With the stock setup I now have this method results in instant smoke.
[/quote]Exactly; me too.

0700700

just a quickie....

80-120*km* times on both cars with manual gearboxes in 4th gear

545i > 5.9s
550i > 5.2s


from bmw website :0

swajames

Both times are "in gear" and in neither case will reflect actual times which will be quite a bit lower....

of course but the difference isnt 0.2seconds like the dash to 100km/h ... by looking at the torque curve
you can clearly see that max torque arrives earlier and is held for longer... also the curve is far more flat (around the maximum value) than the 545i engine.

Plus the engine is 12kg lighter...


So technically speaking if you raced the two would not be far apart (standing start) but in any gear the 550i will pull away from the 545i ...

Hi Ray:

Where do you find the torque (and/or hp) curves for the two cars?

Thanks much 700700. HNY. Oh, and, by the way, do you have anything from English sources?

Whats the problem? Wetterauer speaks English very well. Go into their site and select English. Well respected tuner in Europe.
