Yes consistency is the ultimate goal.

Chris is changing super smooth. Very nice.

1.19s are possible in the 964C2 Dave. Paul is dipping below 1.20 with almost identical weight/power ratio.

The thing we have to remember is Chris as 2000-3000 laps at HD. Paul is well over 1000 by now I should think and Peter probably around 700. It takes time and practice (like golf).

Looking at the plots its evident why a dual clutch or sequential system saves time over a longer course. All those quicker smoother shifts save moments of deceleration and add up I guess.

Yes, it is an evolution to a new level but still within the Gruppe ethos i.e. we are not a racing group. I can see a lot of laptops in the pit garage in the future.

So this is a perfect lap splicing all of the selected laps together? If so I didn't even know that functionality was available. I'll try it tonight.

That's it. The result is highly dependent upon exact split placement, so we'd need to use identical track map files to be able to compare the output.

The software for my DL1 also provides simulated best times based on power/weight/traction/aero parameters entered into the program. I don't think I've found realistic values for this yet, as the simulated time is rather optimistic (1:10s).

Looking at lap times on the PCNZ website, Peter Millener's mk1 GT3 has done 1:13.246 and 1:12.200. Aside from the vast difference in driver skill, I wonder how close to standard his car is...

Peter is a very accomplished driver both Targa and track. His 1999 GT3 is probably around 1300 kg wet now (stripped interior, lightweight Rays allloys etc). Aggressive geo and plenty of suspension goodies. That said Id imagine hes no more than 380 bhp. If he can run a 1.13s at HD I would say that's about the best benchmark you could aim for as all things considered your two cars are probably very close in power/weight and overall config (light wheels, r compounds, plenty of suspension upgrades, aero etc). Not bad tho for a 15 year old car! IMHO 1.10 or below is not territory you will find any road GT3 easily hitting yet no matter how good the driver. Cup car with driver yes but road GT3 no (even a 997.2 GT3RS would be struggling to get there with a good driver IMO).

Dave Mack's 996 Cup Car does high 11s on slicks so I'd say 10s are unlikely in a 911 on R rated tires, maybe the 991 GT3?

Given slicks are good for a second I'd say if you were doing high 12s in a street legal GT3 you'd be pretty damn happy!

Macca

Totally agree.

Its hard to find data on Porsche running at HD. This bad boy bellow (2007 Factory RSR with uprated manthy racing 4.3L engine making 589 bhp - naturally aspirated!) is the only way you are going to break below 1.05s that is for sure!

As for factory "road cars" Im guessing the 3.8 GT3 (2009-2010) and RS variant would be around 1.11s with a handy driver. The 991 GT3 is the only hope of getting to 1.10 on its supplied dot rated tyres - the benefit being the new chassis, RWS and the PDK-S I guess....

Macca

Ok...one last listing....just for those designer house proud types (its listed on TM...).

For the man who has everything!

Macca

Ok. I lied. Im trying to make your boring afternoon more fun.....heres a few more for fun (brand new in box and long out of production)....RC cars anyone?

kiwi 911

Is this the $130K GT3 on TM at the moment??

mjg

Yep, nice catch.

That gives me a list of mods to compare against, thanks!

Macca

It certainly is. I believe the engine is making strong power. Theres a bit of weight reduction stuff too. Asking WAY too much money for it IMHO as its worked hard for its living and is in no way an original car any longer. I believe it should be priced more around 80k. Makes Matts car look like a super bargain!!

KiwiSean

Heck, you could buy the red 996 GT3 Evo AND an ex-Bridgestone 964 for 130k and probably have change.

peterC2S

Are there any ex Bridgestone 964s for sale currently?

Macca - need to break out the lesbots again to fight the spambots...!

John McM

Matt, I dowloaded the Map, the only problem is that I can't work out how to select the laps for that function so it comes up with up with a completely bogus number given of the partial laps recorded on that day.
