Depends on how much HP you have and how shitty your car turns. I've seen a few cases where it was DAMN close, but I've never seen one we were sure it would be faster to hit. Obviously I wasn't at this event so I can't really comment on this exact situation, but it is highly unlikely.

The cone in question I would never say you could save 2 seconds on. Maybe .5 -.7 at best. You would need to nearly stop to have a single cone save that kind of time. - AB (who has pondered such thoughts at National events)

DCCD = Driver Controlled Center Differential

It has an auto mode, where the computer takes inputs from various sensors and decides what to do, and it works okay at the right grip level. If you exceed that grip level, or the grip decreases below that grip level, it gets really stupid. Oversteer, understeer, back to oversteer, horrible understeer, etc.

Switch to manual mode and you can adjust the amount of lockup the computer gives the center diff without it deciding to change that amount mid-turn. Turn the dial all the way forward, it gives it full lock. Turn it all the way to the rear, and the center diff doesn't lock up at all. Since the open center diff's torque split is 35/65 front/rear, the rear tires will spin first. "Full rear" is actually full open, so it becomes a rwd car. I liked the setting about 2 lights up from full open for autox - good amount of rear tirespin, but the front tires were involved enough to pull it in the direction I steered. For driving on slippery stuff like gravel or dirt, I would lock it.

Most people never explore what the DCCD is capable of, so they complain constantly about how badly the STi understeers in certain situations.

IIRC, Donnie/Chris/Jonathan run theirs in Auto all the time, but I think the program for the '05+ STi's was different. - AB

05+ auto mode works better (more sensors, smarter computer, diffs were changed), especially when the suspension is modified. Mr. Herring liked the same setting I liked on my 04 when his was on stock suspension, but started using the auto mode after modifying it. He had an 05.

Agreed 100%. I made it through there a couple of times without braking so even .7 seconds might be generous.

We could try an experiment during a setup day to see what it would take to actually make a "2 second cone". With 3 cones and a datalogger, I bet we could figure it out in under 30 minutes.

Are you going to use your dinky little Jap car, or a big 'Mer'can V8 sedan?

I'm thinking Walter's car would be the perfect test vehicle.

Jim

Any time!

Not sure I'm going to be very much help here as this was not my best event and I'm still figuring out how to drive the darn thing. I *can* say that I did ONE high rpm launch - and it wasn't worth it (but it was darn fun - Bernie (working start) might have even heard me yelp). While I didn't mow down any cones (at least not at that point! ), I had to completely get out of the gas to make the first turn. I think the remaining launches were at about 4000 rpm or below and that seemed to be about right. But again - I'm still figuring out the car.

As for the first two gates.....not sure if I even remember. I beleive I went with easy launch, light throttle to the first cone and then hit the gas. Pretty darn helpful, aren't I?

Since it gave the S2000 such problems. I think that all the starts from now on should be like last weekend. I was launching at 3500RPM and backing off slightly because of wheel spin and then was full throttle till I shifted to second just before the slalom.

Looking back the course was about perfect for the Boxster. The launch was good(who needs a limited slip when the motor is over the rear wheels). The slaloms on the taxiway were not that tight. I was in the variable valve timing( what a mouth full I quess they couldn't call it VTEC) all the way down the runway. Torque is at maximum and flat when the variable valve timing kicks in between 4500RPM and 6000RPM. I didn't hit the revlimiter till just before the finish.

The start was one of the grittiest I've seen in a while. I launched at around 2500 and maybe 1/4 throttle, then immediately had to feather the throttle and keep it dialed back until about 1 second past the first cone.

I guess my favorite two starts were Pastorious's giant offsets course at the Golden Knight's end of Laurinburg two years ago. The concrete was really grippy, and I was able to pull off full throttle 3500 RPM launches, just like Super Ford Magazine used to recommend for 5.0s. My second was a night series RBC course in the summer of 2003. Not a long distance to the first 180 degree turn, but it was uphill and the pavement was clean. I upgraded to the "King Cobra" clutch the next week

Rodney is a waxer (but in a good way)

Last Run. Clean but slow.

I did grab a shift to third on the taxiway, but wasn't in it long enough to even get my hand back up to the wheel. I think it was faster. Just enough to almost make me pay

And then there's this one: My third run.

I was expecting a lot more slide on the sweeper and need to correct there since I had more grip. Incredibly late on the FAST part of the course. I look in the mirror at the end to see if I got the cone.

The first part of the course looks painfully slow in both of these. I want get these overlayed or PIPed to know exactly where I was faster.
