In car GTRS Brands Hatch GP with real time data logger
Discussion
Guys. This is the final edit for the total911 download. I've posted it again because fastfilms have added a natty little real time data logger visual for the two laps with the least amount of traffic - I think about the middle of the download. Anyway, you may find it interesting. It starts just after I pass Tim Chandler's beautiful GT3RS and appears as an additional window at the bottom of the screen. It is a GPS based system. Note how constant speed is after turn in until apex. Also how crap the accelleration G is compared to braking G.
The Roosh Mustange at the end of the clip was being driven by a Mr Justin Wilson. So that will be Porsche 1, Ford nil.
Hope you like it.

Steve, as I mentioned on the last thread...great piece of driving with good technique. Footage is a lot better than last time and miles better than Spa. You put me to shame!!!

Amazed you pop down to 2nd before Sheene's, you can hear the engines screaming way up in the rev. range, couple of seconds your forced back into 3rd then back down to 2nd for Stirlings. Barely enough time to get back to third and then down to second again. All looks somewhat busy.
Same for Graham Hill, short squirt from druids and you've gone from 2nd to 3rd then back down to 2nd for Graham Hill, the third as soon as you're onto the Cooper Straight, then 2nd for Surtees then as soon as you're out of Surtees 3rd again.
The car obviously has plently of low down torque, you're happy to do Westfield in 3rd when the engine revs are audibly lower than other corners.
Can't imagine it would be an approach that would work for the majority.
But then what do I know....

Hi all,
Had great fun filming and creating the clip for Total 911, Steve and others on the day. Just a shame you can't all view the full quality DVD, still, we managed to get this clip a reasonable file size and quality in the end.
The data does add something to the clip, particularly for me in the speeds achieved at the end of the straights, and how quickly the car decelerates, as well as the balance on the throttle through the corners. A pity the data logger doesn't also show vertical G, as the compression you feel at the bottom of Paddock is amazing.
Cheers, Dave

An option of the traditional heel and toe is toe and edge. It involves 'plipping' the throttle with the right side of your foot (easily acheived in a 911 due the proximity of the pedals) and allows far better modulation of the braking and less foot movement - and sprained ankles!
That's exactly what I do!

He went to my school! But whereas I am the fastest GP in Northumberland, he went on to become the second fastest Champ Car driver in the States. I'd rather be number 1!!

Yep - me too. Glad someone mentioned this technique as I think it is a more efficient technique that allows [me] more precision in modulation of the throttle blip. I've found that using the heel is a bit ham-fisted and you often over-rev the engine instead of allowing a 'flat' transition between the blip and the clutch re-engaging.

and me. It makes it easier to "roll" onto the accelerator pedal and get back onto the power quicker leaving less of a gap after coming off the brake

Yep. It's quicker for me that way on the logger, but it's whatever works for the gearing, engine and driver. The RS engine pulls hard at 8000 rpm, and it is relatively long legged. It is easy to balance on the throttle up there but looking at the footage I can see where you are comming from especially if you are used to changing up at a 1000 rpm earlier. You couldn't do it in a cup car because the gearing is shorter. Not sure about the gearing in a 993RS but I'm guessing that it's shorter also so added to a lower rev limit I would guess that many of the corners that I take in 2nd would be 3rd gear corners in an earlier car.

Yep, its a good alternative. I works really well in single seaters where the pedals are close together but I can't modulate the brake well enough in a 911 to make it work properly because my feet are too narrow. Drivers with wider feet definately have an advantage for using this technique!

Not sure what the relevence of the 993rs comment is, I don't own one and was commenting with regard to a GT3.
Sorry, Did'nt realise it was you John. Assumed that you were a 993RS driver not a GT2 driver. Not sure of the gearing on them or the rev limit on the engine, but i would be surprised if you wern't in third at Graham hll and sheene? With all that torque I'd be interested what you would take Surtees in?
Getting back to your question, yep, even with the change it is quicker on the logger.
