Matt N,
Thanks for the update.

If you really want better lap times you need good drivers...

Matt N,
Thanks for the update.

By far the best update I have seen yet.
Thanks Wesley
Just another X-FSAE guy, WAITING PATIENTLY FOR UPDATES!!!!!
Design Semi-Finals, Who is in?
Jack, both spindles in the picture are for the front. The rear are the same but without threads and with internal splines for a stub axle. Although that design has been obsoleted out in favor of a...
Here is the center lock nut(Knock-off nut to dirt track racers) and wheel that Chris is talking about. The nut is 7075 Al anodized and only cost 30$ a piece!(Bishop Racing, Oklhoma City OK) But we...
These are the centers we are using. The only problem we have had is finding time to make them on the CNC.

I haven't read the new rules pertaining to FSAE cars, but I do remember hearing that they had to have been to the FSAE competition. My only concern is how someone could maintain one of these cars...
That's great to see outside interest in a FSAE car. I have thought of building my own FSAE car when I graduate. It sure would be nice to have a lot of good competition.

Sorry for not fully explaining myself

Roadrunner's method is probably the best. We did a test to compare FEA with actual results on our frame before we finish the car. The frame was not complete at the time so we only tested from the...
Thx, I was also needing that

We are not using a dry sump, but the engine is mounted as low as possible. We also measured the cg with a smaller person, so we may try it again with someone bigger and see how much of a difference...
We just finished measuring our cg height and found it to be 10 inches above ground. We were suprised to get such a low value, but then again, what is considered low for FSAE cars.
What kind of...

Good point. There are a lot of renegade forces out there. We will be using a 5 in toe base and about 9.5 in between the A-arm pivots coupled with 0 scrub and a torsion and bending stiff upright.
...
What about the scrub radius in the rear. Eliminate scrub radius and reduce the forces on the toe base. Then you can save some of the space in the wheel for greater separation of the upper and lower...
Why doesn't someone just try it and compare times. Get a good driver that's not too heavy and start adding lead weights to the car close to the mass centroid. If the time improves then your know for...
Sounds like a fun project
I have been working on a wheel center for a three piece wheel. As far as material is concerned I am using 7075 T6. As compared to magnesium it is about 1/3 stiffer and...

What kind of openings did you have in mind for someone graduating this May

We considered building our own Shock tester. Instead we just used an MTS (Material testing system) machine. It already has a calibrated load cell and you can define the velocity. We just set it to a...
