mtg,

I'm the engine leader/team captain for BYU. As far as suspension goes, it has been our weak point this year. Our car could have been much faster than it was, but we never got the suspension dialed in as you mentioned. As for design finals, we were told it was our engine, drivetrain, and weight reduction (437 from 528) that got us through. In enduro, our first driver misjudged that corner, spun, killed the engine, and a still unknown electrical problem kept him from restarting. Apologies to those who were stuck behind us. Lack of testing really hurt us in all the dynamic events. Congrats to A&M for two in a row and to OU for #1 in Design.

At least the safety crew at Indy had fire extinguishers and were there relatively quickly... wish the same could have been said for the OU fire. Thankfully it put itself out after a second, but it could have been much worse.

That's how we roll.... on three cylinders. We found the problem after the first auto cross run, fixed it and ran the rest of the auto cross runs. Then we took it back to the dyno and got it up to 59hp.

We left it alone figuring if it's not broke don't fix it and the car never did run right during the endurance. I haven't looked yet, but it felt and looked like it dropped two cylinders for some reason. We would have still finished, but the fuel pickups that were supposed to draw fuel from one side or the other of the tank in case one side was in air decided to pull both check valves closed and the car stalled out with about a lap and a half to go. As soon as we got home tonight we turned the car on and it started right up without touching anything since we pushed it back to the trailer after endurance. It was still down two cylinders, but at least it was running

jakez,
No need to apologize.
It's pretty impressive what you were able to do in your second year.

I know that mtg is talking about this:


(Sorry if the image is huge)
This is from the autocross - the left hand uphill on the far side of the track.
Many of the cars were disturbed/upset by the bump at the start of that turn.
The BYU car absolutely bounced on it though.
The image above is not from cornering so hard the car lifted.

Fun picture either way. Good luck next year.

I'd like to thank Oklahoma for letting us borrow their CO2 regulator on Friday and Saturday after ours failed. There is no way that we would have been able to complete our accel and skidpad runs if we had to wait for a team member to buy a new one.

Alright,
I've culled the herd a little.
This is the best of my Dynamic pictures:

Lehigh's muffler is starting to lose it. That's packing flying out. A few other pictures around this one in the Gallery tell more of the story.

Fair enough, you still made a very impressive showing. I was just curious, thanks for the explanation.

Sorry for the lack of zoom but blame that on the camera.

After the accident all the fire trucks arrived in a timely fashion, nice work FSAE West organization!!

The EVs (emergency vehicles) were California Speedway staff, so they're used to playing with the big boys (NASCAR). I'm sure the moment they saw flames they were already in drive and going to the site.

I don't want to complain, but the corner workers had a terrible reaction time to the incident. I was on course spotting for our photographer and noticed that the corner working team located before the incident did not yellow or red flag until well after the EVs showed up. Infact our driver was well before the corner (~20 seconds up course), saw the smoke and fire, looked for a flag, and proceeded past the corner when he saw none. There was no flag until after he passed the scene, and had to be directed by a worker around the incident. In every autocross/HPDE event I've participated in as a driver or worker, the moment you see a car gush fire out the back you do something besides stand with your hands in your pockets. I know the course steward probably wanted to control all flagging actions so there might have been lag there, but throwing a yellow flag would have been my first instinctual reaction. Particularly if I'm the corner upstream of a car on fire I would have done something to ensure the safety of the emergency crew, drivers, and responding workers.

I know the workers were volunteers, but they seemed to be fairly lackadaisical during the incident. Just my $0.02.

I saw another instance where a car had been leaking oil all over the track, the crew threw down kitty litter, but then they didn't have a red and yellow flag to throw so they just stood there... seems like at least a yellow would help since it was in a very tight corner. After awhile they got a flag, but this was the main flag man, it seems like he would have known what to do to slow down the cars out of anyone on the course.


Also while driving with our car off the pace I some how chased down a car. The blue and yellow flag was flown for what looked to be the car in front of me. They did not pull in at several passing lanes, so I just thought they were ignoring it. During this time another car had chased both of us down. Once I finally passed the car in front of me I was shown the same flag so I immediately pulled over and they let a car pass me and then held me until the first car I passed went by. Once back on course I was shown the black flag and told I had ignored several flagging stations.

If they want the second car in line to pull over they need to have a better way of notifying that driver. If I ran someone down and the flag comes out in front of the front car I'm not going to pull over unless they show me something else to tell me to get out of the way.

I guess I'm partly to blame, then. I was on the opposite side of the track from where the car blew up his engine. One issue is that we each had our own little section to be responsible for, so if something happens behind or to the side, there's a delay before you know. Plus, us cone weenies weren't given yellow flags, though we did have red ones. Then there's the question, do I red-flag on-coming cars, or run for the fire extinguisher. I chose the latter, only to be very nearly run over by the fire truck... That said, yes, you're right about slow reactions.

First off, I would like to congratulate A&M, Purdue, Toledo, and the other top finishers of the event.

Secondly, here's the video of 'ricky bobby' as performed by Ohio State.

There will be updates here every day.

OK, I finally got all our pictures uploaded, all 1884 of them...

Loooove them hubcaps!

I knew that you and the other grey-shirts were mostly just cone-shaggers with no real authority. The people wearing whites should have known better. My complaint was that the three people wearing whites at the far east end corner of the course upstream of the incident failed to yellow or red flag oncoming cars within 10-15 seconds of the incident. Sure the incident was downstream of the station, but you can't miss something like that. Not between three people. *shrug* What's done is done, I just was worried about the safety of the EV crews and the OU driver. I suppose it's a good thing our (TAMU) driver was more on the ball than the corner workers.

(Thanks chuckBYU)

So did LeHigh get pulled after there muffler became a fart can?

Good to see they got 30 after the bad luck at MI.

Hilarious, that's exactly what I was saying at the comp.

Would anyone like an in car video of the autocross event?
Driver 1, Run 1

Edit: I should point out that the wrong map was loaded into our piggyback on this run. That's at least one of our excuses for being so slow!

Will get around to posting more tonight or tomorrow. I've got video for all of our autocross runs and endurance.
