Default New personal best at SP Main

Here's the video of my new personal best at Summit Point Main, this past weekend. Yeah, I know the video sucks, I think I'm going to be a VBox on my Christmas wish list (hey Evan, we need to talk .... ).


I was actually on track (no pun intended) to get a couple of 1:19's, but got hung up in traffic going into turn 10 both times.

suggestion...just based on that ONE lap.

you are pinching off turn two. let the car run out to the left edge of the track on exit, then don't drive down the right side of the track to turn three. that ain't the shortest route. make a line from left track edge at T2 track out to the turn in for T3. you will find that you gradually cross the track center half way there. i teach students to aim for the T3 flag tub as soon as they exit T2 and it takes them straight to T3 turn in point.

if you pinch T2 and drive up the right edge of the track to T3 you are losing time. this is really obvious if you stand in the T3 tub for a session and watch cars.

disclaimer - i don't drive porsches, but i have been racing BMW's and instructing at Summit for 17 years. any suggestions i have may be useless for your application!!

My biggest comment would be to work on throttle application. Seems you are very late and heavy footed....no real builds or transitions....more of an on/off
Make your goal that a passenger has a hard time feeling whne you go from brake to power....
Stable platform is key

Car definitely screams, nice lap and congrats

I teach a different line than marshall but its always fun to try out different lines and go back and check the data....(video, harrys, vbox, aim, whatever it be)

Let me know next time if you wanna try out the Vbox for a session, if I have time im happy to throw it in and go over some basics afterwards...it can be eye opening for sure. Hell a stable camera would be eye opening....maybe just go slower and the pic would get better

Thanks for posting that, Bill. Are you still running RE71Rs? I’m trying to work out target speeds for 3, 4, and 10 because I think I’m about 5-10 mph off.

Yes, still on RE71Rs. The video above is the last run on those tires, since they were basically bald after that. So, on a good note, they really are good all the way down to the cords.

Work your way up in those corners in small increments. Every car is going to handle differently, and you can't really judge the limits of your car by how a different model handles.

Paul said the RE71Rs have more grip than the NT01s, but the NTO1s will last longer. Interesting. Love the RE71Rs.

Impressive, Bill. Very impressive.

Nice lap but will be interested to see this on something else besides Harry's or whatever that is. The vid shows 34 min in T2 which is way too low and I think 88-89 at the apex of 3 is a bit optimistic and speeds seem to be off in other areas. Time to buy a Vbox from Evan.

Aaron, not sure on street tires but w/ a dialed in race suspension / 964, you will probably want to aim for a min speed of around 76 for T3, 96 min for T4 and 76 for T10. Those are just guesses though as I've only driven street tires at Summit a few times and that was a long, long time ago.
