Engineering is awesome: Doing Lat G vs Tire vs Camber test for credit, need help.

on my to-do list, I haven't had a chance yet today.

David, why don't you as Chris? He may have hookups through SCR.

[Bimmerman325i]

I definitely will. It's the easiest option. Loveland has a dog track too if I remember right, we brought the fsae car there a few times.

Give dicks a shot anyways, just verify it is a school function and for the greater good of society.

1. Yes, contact SCCA and get the deal on dicks sporting goods place they always go to.

Will do, but I'm pretty sure the SCCA/BMWCCA pays to use the lot.

2. Can I attach the G-meter to my car and do a skidpad test?

I don't see why not

3. Lets HD Hero this right at the tires to make your presentation awesome.

Hell yes! I was thinking of in car, out of car, and a couple left/right cameras would be sick. It's a poster presentation, but I fully intent on making a video and youtube-ing/having laptop set up next to the poster.

4. Who's teaching it this year?

Carmen Pacheco. I don't know if she was sr lab prof last sem, but she did measurements then.

parking lot up on 28th and iris where the pleasure shop and drivers license place is. You can def fool around in there, its not so crowded, just have to mark off the pot holes and loose gravel…

I have toyo proxies on 17x7.5...

as for your question about location...I went to CU but it's been awhile since I've lived in Boulder. I good idea would be to contact the local SCCA Solo organizer and ask what property they use for autox. They could hopefully put you in touch with the property owner and you can go from there. Or you could ask the SCCA if you could share the space they use during an autox event, if the lot is big enough to hold their course and your skidpad. Their season should be starting shortly and the timing might work out.

Another idea i have is to contact whoever runs/owns what's left of the old Denver airport (Stapleton). There should be a lot of concrete for you to use there...if it's still there.

Good luck and post your results please!

A. This sounds awesome and fun and even useful.

B. I have no ideas for parking lots you could use all day.

C. Tell me when it is happening and I can do some video. That would be fun.

This is so cool. PLEASE post up some results when you're done, I'm sure many of us here would like to see some graphs of camber vs grip

Thanks for the feedback. I did tire and suspension tests for fsae as well, what school did you go to? We are still in the brainstorming process, and are trying to keep the scope as small as we can. If i was doing this like fsae, itd be too complicated, we are going to keep as much constant and low cost as possible.

I go all out. I'm at MTU. I was originally thinking this was a senior design deal, where you have a budget etc to do your research with.

Im still thinking of a place to do it... You would have to probably rent a place, I am sure you can't legally set up a skid pad area for free.

There are a lot of things you are missing on this test, or haven't mentioned in the post. Are you going to change camber on only the front tires? Are the tires all going to be shaved for best grip? Are you going to be taking temperatures, tire deflection, tire pressures? Are you going to measure times for left and right handed runs?

I've done tire testing for formula sae and our procedure read like this:
Pressurize all tires in shade, check temps on inside/middle/outside in 3 places to make sure starting temps are equal, mount on vehicle. Run 3 sets of two laps each direction to warm up tires, run 1 timed lap each direction, and check temps on the outside tires. Check pressure on all 4 tires, then check tire wear front to rear.

This is repeated until the data from two runs is rather close, then camber is changed (we started at 0 static and went to -4 static).

I may be missing things, but this was done last June.

.....senior lab. That is the class. I think its called mech e lab officially, but its sr lab.
