Yeah as a Volunteer, Organizer or Racer the last thing you want to hear on the Radio is Full Course RED, Stop In Blocks.

On a side note i will be uploading my pics later this evening, i did not get many different angles because i was flagging the turnpike and it kept busy most of the day. Lots of roll overs, a fire and a near fire.

Congrats to all the trams that finished.

here's one of us over the first obstacle in suspension, more to come as we get back to NY and get photos organized.  The race was awesome, the endurance track was lots of fun.  We have helmet cam footage from our first lap and totally cleared the landing on the table top jump (does anyone have a still photo from the grandstand of this? we didnt hit it that big after that...)



edit: it appears that chris reedy may be lurking in the background

Here is a quick pic of our winning car... Many of our team members have more pictures of us and the other top schools but we are all just getting back after the long trip back and it may be a while before pictures are uploaded.

So it looks like Cornell went from Razrs up front and and 489s in the back to Quadcross in front and Mudlites in the back in between S&T and Endurance.
 
Hope you all talked to tech...

C2.6 "As-approved" Condition

C2.6.1 Once a vehicle has passed technical inspection its configuration may not be modified. All accessory components such as roofs, wings, bumpers, etc. are considered part of the configuration and must remain on the vehicle at all times.

C2.6.2 Approved vehicles must remain in "as-approved" condition throughout the competition. Any repairs of a part that is not identical as the broken part must be approved prior to the repair.

C2.6.3 Non-identical parts not approved will be subject to an appropriate performance penalty.

Cornell is the master of controversy at Auburn it seems... magically transorming carbon fiber to carbon steel halfshafts in '09 and shape shifting tire treads in '12!?

yeah, sorry for no explanation -

we transported the car and drove it around in the parking lot at school with some worn out mudlites and quadcrosses (I sure hope we wouldnt run such awful and bald tires at comp!).  That photo was taken as soon as the car showed up in the paddock and was un loaded.

If you look at some other pictures we had some black rims with razrs and 489s on them for comp, had 1 trashed rim from suspension and a flat tire from endurance so we switched two wheels to the polished version of the rim with the same tires on them (and they had the same tires as when we went through tech).

Yea, what Otto said. We ran the entire competition with 489s out back and Razr Ballances up front. We had to use 2 spares but they were 100% identical except the rims were not powder coated black on the spares. It didn't take long for the accusations to start though.

As for 2009, we did change from carbon driveshafts to steel driveshafts when we broke 1 carbon in suspension and then the 2nd in endurance. We did not have any spare carbon shafts and had to get the steel ones reapproved from Tech and we followed the entire process. We talked to tech before endurance saying we thought the 2nd one was going to go but they said we could not change it out until it broke so we ran for about 45 minutes if I remember correctly, then swapped it and showed them the cracked one to get back out on the course.

Our team has never cheated and has followed all the rules for the "as approved condition" when we did not have appropriate spares ready to go.

Congrats on your first finish!  Are you all racing at any other races this year?  It's good to see another Kentucky team competing.  UK-Paducah had a car for a few years, but I haven't seen much out of them in a while.

Did you guys bring spares for the carbon parts this year?  I don't think I would feel comfortable going to any competition without spares.

We had a total of 6 carbon suspension tubes on the car and I made share to crank out a full set of spares right before we left, plus we had a full set of steels that we had been using for testing earlier in the year and we brought them too, just in case.

Just to be clear, we didn't break any of the carbon parts this year despite that fairly punishing suspension course and a rear suspension encounter with a very large rock during endurance.

Well, Sherbrooke had aluminium suspension arms all around. I think one of the front corners failed in the first few laps of endurance. The wishbones were replaced, I think, with steel ones (there are pics on their facebook) but since they did not finish, no one cares. They might have re-approved the new arms though.

Everyone loves to bring up that carbon driveshaft controversy from Cornell but I find it pretty stupid. They did something new, it backfired. The carbon shafts probably weren't that much lighter than the steel ones especially if you consider moment of inertia as well. As Dan said, they went through the proper procedure as well...people should lay that to rest.

Also, the tires swapping thing would have NEVER slipped by the tech during the post endurance inspection, accusing Cornell of cheating is preposterous!

Just to close out the carbon driveshaft discussion, they were on the order of 0.25 lbs lighter each than our optimized steel custom shafts which are way lighter than stock shafts.

The failures in Alabama 09 were from a combined torque and compression shock load that failed the bonded interface, not the actual tube. If you all remember correctly, we fixed this problem in time for Wisconsin 09 (but not Oregon) and ran the second generation there. We failed one in endurance when FEI rammed us at full speed and took out an entire rear corner. The other lasted that entire race. That is why we now always run a rear bumper.

They were designed again for 2010, but not used at the last minute as the drivers and team captain decided they would rather have some ductility and peace of mind than 0.5 lbs less rotating half unsprung weight and any kind of innovation points in design. That decision panned out as we took 5th in SC and 1st in Rochester with a very durable car.

I did the suspension tubes for my Master's project and think the risk / reward here is much more suitable for baja.

Cornell guys,

Why the unpainted firewall?  Seems like there are lots of teams every year that do this.  I've never been a fan of the look, although the rest of your car looks great.

It is not painted. We like the aluminum finish and it matches all of our polished wheel assemblies and gearbox nicely. We actually painted very little on this car to keep the weight down as much as possible.

official weigh in was 308 lbs and when you get that light, yes the paint matters.

I know Michigan - ann arbor was 307 but had to replace a couple bars to pass frame tech and I heard rumors someone else was 306 but it wasn't UMBC or OU who I was expecting and Laval wasn't at this race.

What was Laval's weight last year? I thought they were closer to 320-330lbs.

Good job on that weight, that's impressive.

powder coat adds up, spray paint not so much

I did 2-3 coats on the a-arms and the deli scale we have didnt measure any difference (it reads to .01 lbs so it added less than 1/100 of a pound in paint).

to get paint to look nice over fiberglass or carbon is a different story, takes a lot more material in paint etc. and that can add up fast.  painting metal is generally not as intensive

anodizing the firewall would be pretty cool... but I also like the stock polished look

The prototype cost is in there 0.0...first time I see that!

EDIT: And I am impressed by Sooner Racing. Isn't it there second or third competition? First in acceleration and maneuverability. Congrats!

LAVAL and UMCP did not participate?

Laval is only doing two competitions this year.

Sherbrooke broke their front suspension, replaced it, and then broke their gearbox. I think that was on their twitter/facebook.
ETS had a part failure (brake?), which part is a mystery. But yea from the results, their baja didn't seem to preform very well.

How about putting pigment in your composite matrix?

Last time they included prototype cost it was a mistake. They quickly pulled the results down and censored the cost values. Unless they changed their policy, save a copy now if you want to use the numbers.
 
It looks like general wisdom still holds; you lose one point off of a perfect score for every $100 over some target cost, except instead of ~$8000 for the target (several years ago), it looks like $9000 is the target now.

I can promise you I have thought of and tried everything for body panels in the last 5 years. We used to use automotive primer, pigments and clearcoats and had to sand and fill any tiny imperfections. We did this until the panels were perfect and I think our 08-11 cars reflect that, but we added a large % of weight to the panels by doing this.

We have used red dye before in our epoxies but the part usually looks too murky and / or pink. We dyed all of the Kevlar in our float and fenders black in 2010 and 2011 but it is more of a matte finish to keep from drawing attention where our panels are a completely different story.

Everyone loves the exposed CF look and thinks its something new this year for us, but I have been doing it for 5 years and decided that it wasn't worth the weight and effort this year. It goes much better with the car's overall color scheme this year.

UMCP will be coming to Wisconsin only this year as far as I know. I saw TTU being towed back during the endurance race with a broken tie-rod and I saw them only a few more times afterwards. As for ETS, I heard they were trying out a new gearbox setup this year and they broke the main gearbox and the replacement one so there was nothing they could do to continue at that point. That's just what I heard through a couple people so take it how you want.

TTU had many problems and only got in 1 or 2 dynamic events and a few laps on endurance. I heard they exploded a gearbox bearing on saturday and then I think broke an a arm and a driveshaft among many issues on sunday.

ETS broke their new planetary box twice, the first was on friday on the practice track and was fixable using Auburn's shop but the 2nd failure was during suspension on saturday and was catastrophic. They left before endurance to try to get everything fixed in time for Oregon.

I was Right there both times it broke it just seamed to pop out of gear and then i would not go back in. To bad, there car was quick. One of only a handful that looked real good on the suspension course.

As Danny said, we have broke our new planetary box. We broke it just before auburn (17) in Montreal, after some analysis, we noticed a calculation error on the planet strength. Before leaving Montreal, we machined other gears and they should be ready for Oregon.

We decided to go in Auburn even if we knew that the planetary box had like 90% chance of breaking.

Friday, the press fit retaining the ring gear failed. That was easily repaired with some radial dowel pin.

On Saturday, as suspected the planets broke.

Yesterday, we did some metallography analysis on the broken gear, we also noticed a quench problem that should be solved for Oregon.

We hope to be ready to run tomorrow.

Did it look like they were making measurements for another car characteristics spreadsheet again this year? If so, do you think the organizers will publish it later this year? Was that not Auburn, but Alabama section of SAE that did that in 2009?

The Car Characteristics will be released. Not sure on the ETA for them.
 
The Auburn organizers did it in 2009, as well as the 2012 race.

I was the event co-captain for S&T and saw Cornell's runs. Nobody except RIT* was even close! Cornell hit the first railroad tie on the stair steps, launched, and completely cleared the second step.
 
For endurance, I was stationed between milepost 115-135. Cornell came through what seemed like tens of seconds ahead of the 2nd and 3rd car. Believe they ran a 6:11 lap. Next closest lap (not sure who it was) was 6:48, although I'm sure that was due to all the lap traffic encountered. I joked, tongue in cheek, that Cornell must be cheating since they were going so fast!
 
The endurance co-lead took the old Auburn 2004 test mule (Grandma/Granny) for a hot lap on Monday. Ran a 6:21. I ran a hot lap before the race and got about the same. Not too bad for an 8 year old car with various issues.
 
 
*RIT got hung up on the radial washboard (after the culvert) on their 2nd run, which is a decent chunk of the time they gave up.

We will not be at any other events this year.  I'm not sure yet if there will even be a car next year.  It was planned to cancel the program after us, but I think our team may have turning things back around.  WKU's baja program is set up a bit different than most of the other schools, it is more of a semester and a half project management/prototyping class.

I've got a ton of photos I need to upload.  Caught the Cornell roll sequence during enduro.  I was working suspension during dynamics and got quite a few carnage pics from my vantage point by the rock garden.  I'll have a link to them in the near future.
