faster than a ZR1 around VIR' oak tree turn!

pixelblue · 01-06-2012, 09:43 AM

hi folks,
picked up a copy of C&D lightening lap issue. great article with some good comparo info. unfortunately they used the longer course than what I had run so lap times don't jive with mine but a notable comparo was the speed exiting this turn. as you can see the ZR1 topped the chart with 41.7 mph. I have attached a screenshot from my data log for that same turn showing 43 mph. yes I have R comps but so does the ZR1. I didn't think my car would have had a chance matching a ZR1 in any catagory but numbers show differently and I am very impressed with my little whips performance here. of course I can't match a ZR1 down any of the straights but I thought this was significant considering the vette is 200 lbs lighter than our cars with all the goodies that it comes with. on a side note, really impressed with porsche panamera coming in second around this turn. don't know how they do it but it is amazing! can't wait to see the results once I put in the LSD and a flash tune. it'll be a dragon slayer. lets discuss...

Cool, nice driving. what App is that? Those results seem puzzling though; A 1M faster than a GTR around the same Corner? Yea, the GTR is heavy, but that car was basically made to take on corners like that one..

I could be wrong though

Focusedintntions · 01-06-2012, 11:26 AM

Yandyr...that corner is very tricky to take b/c of the setup coming in there and the elevation changes that happen. Where one car's setup may keep it balanced another may be a bit skiddish.

Kori nice job on keep your speed up around that corner!! You coming out on the back straight in 2nd or 3rd? I normally use 3rd b/c 2nd will just light up the rears

the app I am using is Harry's Laptimer. that particular corner doesn't seem to suit the GTR but I am sure it'll blow the doors off most cars everywhere else especially the uphill esses.

Focus,
I tried both gears but it seem to me 2nd gear was the way to go although have to be careful modulating the throttle coming out of that turn. this was my first time there and there is a lot of time to be made up with more seat time.

Of course I speak without ever actually being at that particular track, it was just odd.. glad these cars are balanced enough to take such a corner at those speeds.

@pixelblue thanks for the App name

pixelblue · 01-06-2012, 01:04 PM

I was kind of surprised the GTR wasn't among the top 3. One would think an awd trick setup as GTR would have done better. The boss was way down even with r comps

xerox445 · 01-06-2012, 01:09 PM

What r comps are you using?

Focusedintntions · 01-06-2012, 01:11 PM

That corner will definately favor a car with a shorter wheelbase as it's a very sharp corner. Almost feels like you're doing a U turn its so sharp. Interesting though in the 1m vs the boss 302 convo going on they show the gran course lightning lap times and the GTR did blow away the 1m on the rest of the track lol.

Surprising the ttrs and cayman R beat the 1m too...

That's another surprise, I would expect maybe the Cayman R to beat the 1M, that car handles pretty awesomely, but the TTRS is a bit weird.

xerox445 · 01-06-2012, 02:06 PM

I don't have any personal experience with the Michelin PS Cup tires, and or the R1's, but are they really that comparable? You know as well as I that the tires make all the difference on track. I could be wrong but it seems its like comparing yokohama ao32r's to A6's. Those 2 tires I do have experience with, nd while they are both "r-comps"; once you drive on both the differences are staggering.

pixelblue · 01-06-2012, 02:18 PM

The R1 are not the best r comps you can get. Hoosier R6 are much grippier. Don't have any experience with PSC or how they'd compare to R1 but I can't imagine the difference would be that significant

xerox445 · 01-06-2012, 03:05 PM

In my experience, a full faced slick is going to be quite different from something with tread. For example, Victoracer v700s to v710s or an r6. Eitherway its a wicked fast carry through you have there. Way to be.

pixelblue · 01-06-2012, 03:10 PM

thanks man and I agree, a slick will always be grippier however, Michelin is on top of their game with their compounds. maybe that'll off set some of the slick advantage.

int2str · 01-06-2012, 03:42 PM

Assuming your screenshot is from an iPhone, I'll also assume that the iPhone GPS updates it's location at a rate of 1 Hz. That is likely not frequent enough to get a good instant speed readout. In other words you may have been slower at some point, but your "average" lowest speed was 43.

Not sure what testing device the magazine used, but likely something more accurate than a 1 Hz GPS.

Not trying to bash your driving at all, btw. I'm sure you put down one hell of a lap. Just pointing out that while I personally really like (and use) apps like Harry's lap timer, I wouldn't rely on it's accuracy to compare myself to others.

Ever thought of coupling that with a PLX Kiwi device?

That way the iphone acts as a dashcam and Harry's will overlay the data on the video. I saw a demo at sema and it was awesome.

great driving BTW !!!!

Yes my sampling was at 1hz while CD was using 10hz vbox. I must say though it is pretty darn accurate. The difference between the two sampling rates on my local track was less than .2 sec per lap

Was thinking of picking one up. I can layer the basic data on my videos but the kiwi will let me get more layering info like rpm and gear selection which is pretty cool

Get the Emprum gps add-on, Harry recommends this one as well. Sampling is 4hz.

How in the world is that challenger #3 on that list? OP, the difference between r1's and psc's are pretty large, but that really doesn't matter. You were moving out of that corner with some serious speed!
