Anyone have this (Neal)?

Just wanted to get an idea of what others are using in the car-setup parameters for things like friction coefficients etc and some other detailed parameters. Trying to set up the model to reflect typical dragstrip conditions.

I think I've got it reasonably close based on what my car has been running but was hoping to compare with some other people's settings too.

 

I can check them when I get home. I'm out of town right now.

 

That's cool.. no rush. Send me a PM or email or whatever.. or we can do the AIM thing

Aha, I forgot about this. I'm home now. What do you want to know. I've got cartest up and running. Static friction I manipulate between 1.15 and 1.25 usually, whatever gives me a reasonable 60' time. Sometimes as low as 1.0 or as high as 1.3. It doesn't seem to affect terminal speed, trap speed, etc.

Shift times is another thing I play with. Personally I shift very fast, one of the reasons I usually have pretty good 1/4 mile times. I've got manual shift time set to .3s and engage time to .2s.

 

Unfortunately I'm at work now. lol.

Hmm... I forget is there a way to export the custom car settings, or failing that send me a screenshot of the two main parameter screens? I know I wanted to compare both static and kinetic friction numbers, but there were several others I can't quite recall right now without looking at the program... basically the more detailed/obscure parameters on the custom page...

So you just play with the friction numbers until they reflect your actual 60' times? That's basically what I tried to do. I shift quickly too but as a conservative first guess I think I set it at .4 not knowing really how long it actually takes

 

Yep those are the two parameters I mess with mostly, other than tire size, vehicle weight, HP/TQ.

I can just send you my entire datafile, you can swap between datafiles if you just move them into and out of the folder the cartest looks for them in. It has some cars modeled pretty well including my old car, Jclaw's 3.5 4th gen, some turbo and SC and nitrous 4th gens, mikeDs I30, tons of other cars I've seen dynos for on other boards, etc.

 

That'd be awesome... thanks!

I am just starting to play with this thing...
