You might want to run the calcs for steering effort and diagonal load transfer to make sure you unload the inside rear enough without killing your endurance drivers, I think Erik Zapletal's papers on...
Both sets of shocks are sold, sorry.

The Elkas are 10.25" eye to eye with a 3" stroke (a 0.5" bump stop is currently installed, so 2.5" free travel). Let me know if you need a CAD model.
The Stratos are 8.25" with 2.25" travel.

We also have three CBR600F4i engines available:
<LI>~180 psi on all four with 4000 miles/6500 km in the motorcycle, one competition in the car and no dyno work; shortened stock oil pan with...
We are clearing out parts from previous cars and have plenty of stuff to sell...make an offer.
2 x CNC master cylinders
1 x stock Torsen differential housing
4 x Wilwood Dynalite two-piston...
You can get linear geometry (or your choice of progression) mostly independently of motion ratio, I'd look at wheel and damper travel first - with typical FSAE travel values, something close to 1 is...
A decently detailed cornering simulation with the tire data can be useful to highlight the effects mentioned by DohertyWins! when you take a look at the slip angles and corresponding vectors through...
Could you please send us the following pic at fsae@polymtl.ca? http://supercarfreak.net/gallery/albums/album334/Shootout90.jpg

Thanks a lot to the hosts, great venue and organization...as for us, hopefully we'll show up with more than three cylinders next year.

Critical damping in roll will be equivalent to 2*sqr(Ix*Kr), the variables being your moment of inertia in roll and the roll stiffness.

In this Pacejka version it's the normalized load increment, the coefficients provided include Fz0 (nominal vertical load) and dfz = (Fz-Fz0)/Fz0.

For all Quebec teams, we will be hosting one of Claude's seminars (en français) from November 17th-19th at École Polytechnique if there is enough interest (30 people), so let us know here or at...
Hello,
We're looking for a full set of Torsen T1 washers - preferably new, using worn ones didn't work out too well.
Thanks-

I'd like to extend our thanks to Cal State Northridge as well, we really owe them after they let us ship our crate to their university then use their shop for last-minute preparation at basically two...
We tried that after some trouble at the FStudent noise lottery last year, didn't seem to register a change though (same for mixture, FWIW).

Just to make sure as we're currently settling travel arrangements for FSAE West- as far as I know and as mentioned in the first post, the seminar is three days, but the OptimumG website says "You...
That was pretty much why I made ours as well, ADAMS is needlessly complex when you're just looking for RC positions and camber curves. I think the learning process involved in making your own...
We got pretty good results last year by logging power and MAP on the dyno, then replotting against TPS. Even in transient runs, it was pretty close to CFD data- I don't know if that was just blind...
FWIW - our set of Brembos ended up cheaper than Dynalite Singles with much better construction.
We haven't tested them yet, but other teams have successfully used them and I really don't see us...

SAE paper #983033 has a good example of an "integrated" approach to this, and it's pretty easy to implement. When you throw in the non-linearities and geometric characteristics, there's definitely a...
