Rob,
we should hit the Porsche Driving Experience when they switch to 997. all 6speeders!

 

Arling,

Why wait? I would much rather do the 996 anywho since that's what I gots! But either way, I'm in! Maybe we can convince, Da Boyz to do it this year. We can get a better price if we take over the entire class. How cool would that be?! 6Speeders take over PDE for a few days. Love it!!

 

talking about pissing the instructors off... Don Relentless must go. he can do DONUTS around da boyz while i'm going the WRONG direction!

 

Yum they serve donuts

 

Oweyea:

You are expressing a very common misconception. Lat g is probably the second most important variable to monitor after speed, That is how important it is. Also, I am an engineer with quite a bit of experience using Data Analysis and you will have to trust me, it is critical to proper analysis.

For most people, they won’t care or notice what I consider absolutely crippled analysis. When they correct the problem, I will go as I have heard very good things about the group.

 

I concur with 20C4S PDE is a great course. They run a class act and have the best of the best as far as instructors concerned. I personally had Hurley Haywood, Doc Bundy and Chip Robinson provide me with instruction. No I'm not much faster but it is a class act

 

Their Data Acquisition provides 3 things, MPH, "Lateral G's" and Engine RPM. They absolutely show the lateral G force that the car is exerting. Yes, the lateral G's show when you execute your turn in, how well you're holding the line and when you execute your turn out. I agree that the lateral G's are critical criteria to determine if you’re executing properly.

I also know the benefits to data analysis and agree that with proper data acquisition and "professional" analysis you can make the proper modifications to extract the best results! However, in a 2 day class you're going to spend "most" of your time just overcoming the bad habits you've created over a lifetime of daily driving. Only "after" you overcome these personal obstacles can you really "nit pick" the stack chart to further fine tune your laps.

What I'm saying Tim is GO Dude!!

Rob:

Are you sure they have lateral g's? I was told and shown grpahs where they showed longitudinal g's (braking and accelerating), not lat g's.

 

After a "thorough" analysis of my stack chart, I've determined that I am "not" correct. Yes, you are right, I believed that the middle section of the stack chart they gave me were lateral G's but indeed they are "longitudinal" G's.

I take back what I said Tim, don't go. You're right without the Lateral G's the class has no value.

 

Rob, come on, lighten up. I never said it had no value. In fact, I said most people wouldn't notice or care. I do, and therefore won't be going until they fix it. Most other people, like yourself, are likely to be very pleased. I would get significant value without it. Unfortunately, taking the time away from the family for sub-optimal training doesn't work for me.

 

wow - that looks like so much fun

 

Rob, you'll have a rollcage in your GT3 in no-time.

 

Noel,

If the GT3 would only come in a cab!!

 

Tim,

I guess we're not communicating. I don't see how not knowing your lateral G's will make the experience any less worth while. Maybe you can explain it to us. I, like most people, realize that the L G's help you fine tune your time around the track. But, since you're never going to race the Derek Daly track again what's the use? You're there to learn and practice several driving skills that are in it of themselves a hand full. I guess everyone has to find an excuse for not following through. I guess no L-G's is as good excuse as any!!



I'm just joking with you Tim.

 

Rob:

OK, no problem I approach my driving very technically. The fastest driver does only 2 things (driving, not racing situations), maximize g forces along the ideal line. Skipping line selection for now, you want to maximize a number called combo g or g sum. G-sum equals the square root of ((lat g)^2 + (long g)^2). So, to monitor if the driver is gatting the maximum capability of the car, you need lat and long g's. This is the best starting point for any detailed analysis. To go further would take a long time. If you are really interested, I can point to links of discussions I have had on other boards and name references.

Finally, don't think that it is only for expert drivers finishing touches. It is much more enlightening than the simple long g only analysis you did.

Final caveot, it doesn't apply as well to those that are not very technically oriented.
