Ryan and I are running on R6s but a 997.1 RS doesn't have a chance of catching a .2 if both drivers are fairly equal.

911SLOW

Gentlemen: for the sake of accuracy please note that according to the published technical information for the 997.1 GT3 you can completely turn off the electronic aids.

I have driven a 7.1 GT3 with the traction control off and never felt that it came back on, even at extreme angles ..





Traction Control/ABS
In “Traction Control” (TC), the 911 GT3 is provided for the first time with a system to promote driving stability during acceleration. This system comes as standard and is used in a similar manner on the Carrera GT. It incorporates the following features:
• ABD (automatic brake differential)
• ASR (anti-slip regulation) including MSR (engine drag torque control)

In conjunction with the familiar anti-lock brake system (ABS) and the Traction Control (TC) system tuned specifically for the new 911 GT3, the latter now possesses a system to promote driving stability during both braking and accelerating. TC supports straight-line stability and overall driving stability in particular in adverse weather conditions such as rain or when varying levels of grip apply on the road surface. When drive wheels begin to spin, the automatic brake differential function (ABD) first of all brakes the wheel with a higher level of slip. If both wheels are spinning, ASR will intervene within fractions of a second. The purpose of the anti-slip regulation (ASR) function is to prevent excess wheel slip on the drive wheels in order to increase cornering traction at the rear axle. The ASR function is activated when accelerating across the entire speed range. As a result of intervention in the engine control system, the engine power is decreased via a reduction in torque, acceleration and ignition angle. When ASR is activated, the relevant information light lights up on the instrument cluster. This yellow information light displays a warning triangle to indicate that the adhesion limit has been reached. Engine drag torque control (MSR) is a function within ASR. This function takes effect, for example, when there is a risk of a loss of lateral stability at the rear axle after a downshift on a slippery surface due to rear wheels locking as a result of engine drag torque. In such a situation, MSR can quickly open the throttle by demanding more power from the engine management system, thereby restoring driving stability.

SPORT / TC OFF
To enable the car’s driving dynamics to be increased according to individual needs, the standard “SPORT” button for Traction Control on the centre console enables a sporty set-up with delayed intervention by the ABD, ASR and MSR functions or, alternatively, the entire system can be switched off via the “TC OFF” button. “TC OFF” appears on the instrument cluster display when the system is switched off.

Carrera GT

There's plenty of video of people drifting GT3's far beyond any point where SC/TC/PSM would intervene. I'd take that mean the system is fully defeated, not waiting for an ABS event or other system to sound the "all hands."

Fritz Flynn

Some folks had suggested the TC was coming on because the rear tires were over inflating but that was because the rear toe was off.

If I forget to turn off the TC I notice in the 1st corner and everything feels normal after turning it off so from what I can tell it's completely off but as mentioned above in the 997 GT3 some people in the KNOW say it can't be COMPLETELY turned off.

The rear pads and rotors wear much slower than the fronts so I also don't think TC is doing much even if there's some ghost of a TC remaining when it's turned off.

TRAKCAR

As far as I can tell off is completely off. I spun GT3.1 180 degrees at 100Mph and nothing was there to help me. I've been behind and gotten GT3 very sideways plenty of times. Off is off.

I had the RS.2 crossed up plenty sideways too and never felt anything. IMHO off is completely off untill you turn it on by button or restart the car.

FTS

I am just catching up to these threads

Niiiice driving Fritz, very fun to watch, not to mention the guitar solo

Next up Hurricane region Master driving sessions in June

Fritz Flynn

Thanks!

Like the rest of us J is getting older but he still ROCKS http://www.picsnow.us/photo-j-mascis.html

Have fun on the south course I'm planning to drive it with FSR this fall

The track time will be soon forgotten but the event will forever linger in my memory as cursed

Just could not get out of town. Starts with one of those chaotic busy headache variety work days and I finally leave and as soon as I step out of the truck in my driveway I realize my tow straps are back on my other trailer at work holding down my FD so back to work I go. Now back at home with straps in hand I find the car is a PIA to load on the open trailer and I'm about to have a tantrum and just say eff it but after tall drink a water I'm refreshed and get it loaded without too much trouble. I finally leave at 5:30 (no possible chance of dropping the car early and going to tech) and there's a serious accident on 81 (40 minute delay).

Finally arrive at the hotel and the poo is still raining down, the computer doesn't show my reservation but thankfully it's there but under Friday/Sat not Th,fri,Sat so no fist pounding required. Go up to the room and you guessed it, my key code doesn't work.........MAN!!! SOME DAYS!!!

Arrive at the track and don't have time to get the car through inspection and because I don't drive often w/ PCA I don't even realize instructors have other instructors tech or PEER TECH so tech wasn't even an issue. NOW is where I really step in the DOODIE. SOOO I go to the chief tech inspector and he notices my harness are out of date (1/2 the people at the event probably had harnesses out of date) so I spend the morning buying and trying two different harness from OG (on site track store) but both will be a major PIA to install so end up borrowing some from "Bret" RP Performance (track side race shop) who's been doing me all kinds of favors for 10 plus years (great friend to have).

Harness fiasco and ball busting HPDE tech insp behind me along with the morning track sessions I'm finally able to exercise Fiona but it's my 1st time at SPR, I'm on old 888s and the track isn't in the best shape so I'm not feeling too groovy, it's basically a blown day at the track but hey my student was good so I'm feeling thankful for that

The next day I get some driving instruction from Rmag and things start coming together so I decide to throw the HOOS on and WOW the car jumps off the mat and starts kicking some *** but it doesn't last too long because I have a very fast leak in the R rear tire combined with RAIN so I pack it in and call it busted weekend.

Here's a vid:
My buddy in the .2 GT3 that passes me into t5 is super fast but he was on 888s and the car was pushing so bad I actually started laughing out loud to myself while following him around the carousel.

I'll post up a another vid from the same session running a 1.20 lap which isn't horrible but also not as fast as I'd hoped. I think under better track conditions and a tire that can hold air the car has low 19 or 18. Didn't notice much problem in the turns but braking was not good, when I came in the pressure front was 35 rear 25.

Fritz - these are the weekend that you look back and realize - it was still fun. Been there, changing radiators with 20 minutes before the race in 110 degree heat at Road Atlanta, rooms not showing up. This is what separates a real junkie from a fake one!

Fritz Flynn

TRUTH BE THAT!

When you track an FD, GT3 or racing anything you're vacuuming the living room carpet, sifting the dust and reaching for the pipe

Brent Dalton

truer words have never been spoken! I'm expecting big things from both of you at VIR in October.

kurt M

Did not know you were a Rennlister or I would have stopped in to say hi. I was the noisy rude white 911. I think I might have some video of your car on track from T1 to T9.

Sorry you had a rough start at SP. The belts is a National thing not Potomac and even the locals have been changing out belts.

Fritz Flynn

Hi Kurt,
Hmm t1 to t9 doesn't sound good hehe, hopefully I wasn't holding you up.

I remember your car, VERY COOL!

Next time I'll track you down and introduce myself

Fritz Flynn

I may not run in Oct. but if Alex is that will give me more motivation.

At the moment I'm planning on it. Trying to get some weight out and with colder weather who knows maybe a 2:01-02 possible for the tired 6GT3.
