Well if nothing else this discussion has me thinking I should "stay the course" and come up with my own pressures.....

My guess is that the higher pressures loosen up the tail of the 8 a little bit so you can decrease push.

It is when you're generating max G loading

Not only is the additional loading going to cause more body roll, but then the front outer tire corner is going to further compress and rollover more

This is a Stock car, not FSAE. You can't make the necessary adjustments in the conventional race car sense. In Stock you have to resort to the unconventional to achieve the desired result

Like running full rear rebound?

Don't get me wrong - I'm not married to the pressures we currently use, and we'll be doing some more focused testing with datalogging later this season to see if we can get repeatable, measurable improvements with a change in air pressures. However, I'm of the opinion that any potential gains are going to be small enough to be lost in the noise of a regular local event, so I'll stick with what I like until we have a chance to really do some controlled testing.

I never ran full rear rebound, I personally recommend 50% and that was running a stiff front bar no less

did Woody pull a TeamRX8 and cone all his runs yesterday

I know. My point was that there is no single "absolutely right" way to set up a car, even with the unconventional choices that Stock class rules sometimes dictate.

Nope, I really drove that poorly...

The surface fell apart in the afternoon (literally)...Look at National Champ Vic Sias' times in the SM car...about 2 seconds off of the fastest morning times

Still, I just had major problems/spins/crxp in the run group. I did 3 fun runs right after and each run was 1.7 to 2 seconds faster than the time I stood on in class

Cooper47

So does that mean you made it into the 39's? I was pretty bummed about the surface yesterday even though I think it helped me drive a little more conservative and potentially smoother. Still, I thought Oakland was the last location that was half way decent.

Here's a video of my last run if you want to disect the course (and my driving) some more. Fun course, too bad there was no grip.

I thought about sticking around to adjust the rear toe and do some fun runs, but I was kind of beat as it was. We had grip problems in the early sessions too. I was completely sideways and lost all my momentum on my fast time. tried to smooth it out on my last run and just went slower. The car felt like it had a low 40 in it ...

I'm surprised the results aren't up yet, I can get to the actual and PAX time list, but not the basic results ... Glenn told me they'd be posted that night

It's up late Sunday night when I checked, http://www.sfrscca.org/solo2/Results...p/round12.html. You can always get the event result link from baautox.com faster than waiting for the main site to be updated.

Wow, Mike, 39sec run? I heard 40.2 on your fun run while getting ready to leave. There is no doubt you are faster than all of us in BS and other SFR folks, in my mind. I'm sure all the talks about Shelby GT in FS is getting you a bit too pumped up for your own good and that of RX-8

did you actually click the event results link, it just brings me back to the results index page

when I was looking on baautox.com they weren't posted yet, late Sunday night EDIT: they have the same link = failure, sent JM an email

you can get to the PAX and Fastest Actual Time page, but not the overall results page with the run by run times, fun runs, etc.

I can just see it now......"Mwood at Oakland collesium, nobody else is there, all the cones have been picked up and it's getting dark but he's still out there try to beat Matts' time"......Seriously, if nothing else I admire your ambition to be the best.

I got to the actuall run-by-run result from the link posted on baautox as of Sun nite. The link always increments the event number but stays the same format/syntax.

The homepage link has been known to screw up.

TeamRX8

iTrader: (25)

I've been clicking on it since Sunday night, same result. I was incrementing the number before the results index page was updated that night and it was doing the same thing then. Somebody else noted having the same issue, 2nd post in the baautox.com results notice thread,

lol, his ambition is not to be the brunt of Ulllose's pointed stick

mwood

I don't know about any ambition, I just made such a mess of the official runs and, since fun runs were immediately after our group, I figured I might as well stick around. I went 40.003 and then got greedy and slowed to a 40.22, so no 39x, but nearly 2 seconds faster than my class time...but, that's with the benefit of an additional look at the course! Matt did great, as did CRX, both coming through when it counted

Being humbled is not a "bad" thing...I should know, I have plenty of experience with it!

What mess? Just a spectacular spin right before the showcase straight =)

We all knew that you had a bad day, while us having a better day than usual. I wouldn't expect anything less but you coming out and beating on us. I should know, since I get humbled every single event.

TeamRX8

iTrader: (25)

as Ullose has so amply demonstrated, the capability to go fast is meaningless, going fast when it counts is all that counts ...

mwood

That sums it up nicely.

But, more seat time is more better, so, while practice runs don't win jackets, there's nothing wrong with 'em...

Something else discovered at the Oakland event: The course developed quite a bit of gravel and sand off line, by the afternoon, with some of the crxp actually on line, as well. After my first run, I dropped tire pressures front and rear by a good margin, thinking that might somehow help on the low grip surface...and, it didn't really do anything. For the "fun runs", I just let the tires go back to wherever they wanted, ending at about 40f/38r with no real difference noted in grip. So, I'm beginning to believe that tire pressures, with the V710's very stiff sidewall, are not really of that much importance...as long as you're not getting big time roll over. On the other hand, I do think that f/r pressure differential is a significant factor.

Reza and I were running 38/35 before run, up 1 down 2 on the f/r hot psi right before my last run.

Many have pointed out the indifference of V710 re tire pressure. F/R bias is indeed more critical, accounting for rollover.

TeamRX8

iTrader: (25)

obviously less lateral grip = less rollover forces on the tire so running lower overall pressures makes sense

the asphalt we've been running on in NV has much more grip than the stadium, we see excess front edge rollover if the pressure drops below 42 on our gauge, 44 provides the best turn-in response and control there

I should be at the next several Oakland events, we can compare gauge readings
