It seems that both BMW & Porsche choose to outfit their "everyday" cars with open diffs & EDL, but put real LSD's on their top performing models. It does seem like no matter how good the open diff and EDL can be, it's not as ideal as an LSD.

Everyone is entitled to an opinion, but I believe his point is sometimes getting an opinion from a person who does not have a true understanding of a particular subject is not always an accurate opinion or one that should be taken seriously. Because anyone can post virtually anything on the web nowadays, it's always good to be cautious when gathering information.

Nothing I said in this thread required expert testimony to validate any opinions I gave. Some people in these threads should spend more time reading what people actually write and spend less time trying to make themselves look smarter then everyone else.

Agreed, and I'm just seeing both sides of the argument since sometimes I get frustrated trying to gather information only to eventually find out that it came from dubious sources. Because we are just typing away and replying to posts, it's always difficult if not sometimes impossible to convey everything on your mind. It's not like having a conversation where questions can quickly be answered. Your comment about the 430 being slow and should be faster does depend on the track as we all know. I must have missed the track layout, but for folks who can't quite comprehend this, tracks with slow to mid speed turns that also doesn't have long straight aways will not favor a car like the 430.

I did jump to conclusions when I made that comment. I got so hung up on the times that were posted that my mind immediately said, "impossible." Unfortunately my emotion upon reading these numbers clouded my judgment as I initially over looked something so obvious as the track length and layout. I believe in my subsequent posts I addressed and corrected myself on that. I have to attribute this error to my brain's ability to think so fast and so far ahead that I momentarily forget where I am. Was it Einstein who couldn't remember where he lived or what his phone number was? I believe myself to have a similar problem. Now if you'll excuse me I have to come up with some solutions to problems we are having at NASA with the Martian Space-station prototype.

No, I agree with you that an LSD would definitely help. Coming around a corner in 1st gear I can get the inner wheels spinning more than I'd like. I haven't noticed this yet in 2nd gear although I would imagine with another 90 ft/lbs of torque the issue may be there. But quickly rolling on the throttle, the 335 has so much more power to pull away from many cars out there including the M3, 911, Evo, etc. (I'm talking about a 2nd gear corner for example, pulling from 2500-3000rpms). The good news is that the power never quites. Some of the higher strung motors/cars out there can't excelerate out of a corner having a lack of torque. Keep in mind you roll on the throttle around a track rather than hammer it halfway through the turn so the worry of the inner wheel spinning is much less.

That's why I like to look at the Nurburgring times because it's hard to B$ the results with numbers there.
This was the post that showed to me a lack of track experience. You outright said the OP test is BS, and I called the flag on you.

I see you have now backed off your claims, and now are starting to understand how different track layouts can favor different characteristics. Perhaps you'll even understand how a 190 HP Elise can kick a 500+ HP exotic on a club track.

The 335i isn't a sportscar, I don't care what the track layout is, if power is similar, the lighter car should have the advantage...especially on a road course.

Call it as you like... The fact is that the 335i kicked some really BIG asses on this track.

All the rest are just "philosophies" to me

Agreed.

Now, since the lap times ARE similar, that tells me the weight/usable power/handling/braking characterstics of the 2 cars ARE also similar, or at least trade each other off in near equal amounts.

Ok ...here you find the the track-map and the times between 335i ,new TT , 350Z (300Hp) & Alpha Romeo Brera

The first column on each table means
1st Column-> Total time
2nd Column->Speed while approaching curve
3rd Column ->Speed while exiting curve

and the last column on K5 ,S ,K10 & K13 is the "distance" (in meters) that each car drove from the beggining to the end of the specific curve as each car needed to be positioned differently in order to achieve maximum speed while turning.
-I hope the last explanation is comprehensive enough-

The picture quality is bad as i used digicam instead of scanner.

Pic is great, thanks!

It looks as though the 335's torque and HP ruled the day, notice how in almost every section the 335 takes up more track? It appears to like wider, classic racing arcs as opposed to the point-and-shoot style of say the 350Z, at least in this test.

This track layout reminds me of Gingerman!

There are so many things fundamentally wrong with this reply I don't even know where to start. First of all I'm still calling BS on this test, it's just that you don't seem to understand exactly what it is I'm calling BS about. Second, I don't appreciate you calling BS on "me" because there is no need to make this personal. If I feel this test is skewed in order to obtain a certain result then that is my right. Furthermore, you obviously either didn't fully read all my posts in this thread or comprehend them. You make accusations and assumptions about me based upon no conclusive factual evidence. In addition, your sarcasm is trite and misplaced. If you need to knock someone else down in order to build yourself up I suggest you pick an easier target. ZZZZZZZZZZ

You just cant stand the thought that the 335i is performing better than m3 on the (this) track...thats your problem.
Its yor right to believe what you want but the numbers proves differently.
