um i can see it fine if thats what youre asking.

otherwise, kinda disappointed he couldnt catch up to the bmw. i didnt like his line thru the carousel and it seemed he wasnt on the throttle as much as he should be, but thats easy for me to say. i timed a 2:01 lap time. slower than ITA pace...

the 928 ran some 1:59's that day I think. it is only on street tires tho (s02). the m3 is on toyo's and also has the euro engine with 6 spd. it ran some 1:58's with driver/passenger (so weights about 3800 lbs) that day.

ITA record for Sears Point is now at a blazing 1:56... that's fast.

yes... the driver in the porsche runs in lot of advance groups in cali. he tends to counter steer instead of getting on the throttle earlier to balance the car. this is a common error that a lot of advanced driver make.

is it necessary to double-clutch downshift in that car? he seems to struggle with it on a few turns, and you can hear brief lockup on one or two occasions.

and the tires scream like mad with almost any steering input.

just my observations.

I've never driven the track, or seen it for that matter, but he seemed to be taking a couple of corners using a very different line than I would, or than the M3 was. The car also seems to understeer pretty badly, and he almost never had to feed in any opposite lock, so I don't think he was applying the power early enough, or hard enough.

Is the track really short and tight, he was only using 2 gears. I know the car is a torque monster, but you'd think he would at least use 3 gears, what with that really tight harpin.

What was the car with the black rear end that passed him right at the end? It sorta looked like a Z06, or maybe a Saleen S7.

I'm pretty sure it was a Z06, but I am certain it was a Vette.

Ditto, does the guy have a model T tranny or what? It was almost painful to watch that video hearing those tires getting obliterated.

That's a Devek-modified 928. No doubt it's a handful.

his line is not perfect but pretty good. his car doesn't understeer actually, just those tires are noisy (it's also a pretty heavy car even stripped down; went from like 4000 lbs stock to like 3400 lbs).

the track is Sears Point. It is 2.5 miles and a very busy track, hardly any straights (see map below). Hmm, his car must have pretty tall gears as he only uses 2nd and 3rd (his gear shifter left up is reverse). Data below are taken from a well driven Viper...




the black car is a race prepped Z06 which turn like 1:55 or faster that day. anything below 2:00 laps at Sears Point is not bad at all, especially on street tires.

his steering inputs weren't very smooth a lot of the time.

Oh, I misunderstood the question about which car was the Z06. Nevermind.

Driving in the 2nd video clip is much better.

In the first clip, it seemed he was apexing too early especially in 8, 8a, 9. It might be that he just didn't get back on the gas early or hard enough as was mentioned above to rotate the car. Speed thru 2 seemed slow-mo. Hit that straight section on driver's left after the brake/downshift & be back on the gas @ turndown. I also agree that it doesn't look like he pushed the car thru the carousel. 10 looked early too. Line thru 11 actually looked good except he didn't track all the way out.

I should've posted the driver's own observation from the fast lap video:

"Had it not been for both the datalog and timecode on the videotape, I would never have believed this was my fastest lap of the weekend. The errors I see include:

messing up the entry to turn 2
getting on the power late in 3A
charging too hard into 6 and never make the apex
bungling the downshift before 7
easing out of the throttle too much in 9
On the other hand, the best parts of the lap are the exit off turn 7 and the speed through 10, which according to the datalog, was the fastest I ever went through there.

Sears is a tough track to learn. Trying to keep your foot down through turns 1 and 9 is, to say the least, stressful. You're going about 110 with all four tires screaming and tire walls only a few feet off the edge of the track. And there were a couple times where I was wondering if I would stop sliding before I ran out of track at the exit of 10.

After that session, I spent the rest of the day trying to get smoother so I could eventually go faster with less effort."

he goes into second for T2, and T7. which overslowed him. i'd recommend him to stay in 3rd. i stay in 3rd even in my civic. i only go into 2nd for T11. how about you mike?

Given that the dynamics are different for his car, it is hard to say. For the most part, I agree. If it was my Civic in the video, I would downshift from 4th to 3rd for T2. I would also hold 3rd thru T7. I would take the 'push' thru the first part to get the better exit (speed) thru the second part.

The driver made some good observations about his lap in the second clip. I wonder if the problems that he had in the first clip were because he was chasing the bimmer. I am sure I state the obvious when I say it is much easier to drive clean when there is a bunch of open track.

Funny, how easy it is to see the mistakes when you aren't the 'driver'. The clips remind me how much I need to improve & work on consistency myself.

going on higher gear works for all cars to carry more speed through. lot of ppl tend to down shift too much. i'm certain it would work well for the 928 too. the driver is better than the 1st video would suggest. he is still learning just like all of us too. he's really no slouch tho, as he turned a 2:07 at thunderhill full track with R tires in the 928.

"After that session, I spent the rest of the day trying to get smoother so I could eventually go faster with less effort. Here's a sequence of laps where I let a faster E36 BMW M3 by and we both chase a Viper ACR."

now check out this video. driver's description:

"In this vid, I get held up by a brand new Porsche 996C4S for a lap. By the time I can pass, a new 911GT2 has caught up to us, so I let him by at the same time. Watch me get SMOKED as I fumble the hairpin exit and his turbos kick in. A fast driver, a fast car and race tires make for an absolutely devastating combo."

jump to 2:25 mark and check out the sequence. does it look familiar anyone???

Couldn't help but throwing that one in there huh? The only difference here is the 928 crawled past those 2 cars instead of absolutely blasting by mid turn. I really cant believe your brining this up again.. I guess you would like 4 more pages of attention?
