[Jon Huddleston]

I have not seen chalmers wheels from what I can remember. Their's carbon as well?

[Denny Trimble]

Yup. Photos by Pat Clarke are available here:

How heavy is that wheel including centre

[Jon Huddleston]

I'm pretty certain a wheel with bolts and center is 4.8 lbs or about 2.2 kg. We are using a 4 piece mold. It took a while to get it all figured out, but inside/outside is smooth with no machining. The wheels have done pretty well so far, no on-track failures, tires go on better and have less leaks than the old aluminum wheels. We had some bridging problems with the first carbon we used since it was not "hexel quality" and we've broken one/damaged another from a "discount tire trained" tire changer. Inexperience can be pretty expensive sometimes... Anyone know Chalmers weight? It looks pretty rough on the inside but overall looks very cool.

Check out the Delft Rims, the show them first @ FS 2003!

[MH]

Our last years rims weigh 1.4 kg (front) and 1.5 kg (rear). Including center, bolts, valve and balancing lead. No worries with them.

Delft's are 10" rims and UTA's are 13", by the way.

http://www.dutracing.nl/ go to "pictures 2004" then "rims".

[Mad Ruska]

2003 they had 13"

[MH]

You're right, our 2003 rims weigh 1.84 kg. You don't want to know what the weight of our rims is going to be this year http://fsae.com/groupee_common/emoticons/icon_cool.gif

By the way the 2003 rim's can also be found under the 2003 pics (http://www.dutracing.nl/html2/car03_pagec.htm).

So let's say you get your whole car down to about two hundred forty pounds. At $100 per lb, thats darn near the $25,000 cap right there.

Oh, I forgot your carbon engine would be costed only by its displacement.http://fsae.com/groupee_common/emoticons/icon_smile.gif

The Chalmers 2003 13" wheel was 1450 grams something I recon. 950grams aluminium and 450 grams carbon plus some bolts The two parts were sealed with an O-ring. The inside is rough because we used a single mould with vacuumbag and the smooth surface is towards tyre and O-ring. Cheap and simple but not as *Bling*

UWA talked about two piece alu/carbon. Anyone know if they did or what happend?

hi all,

our full carbon wheels and centres weighed approx 1.5kg at fsae-a. they certainly created lots of interest! were hoping to get them down to around 1kg for formula student http://fsae.com/groupee_common/emoticons/icon_wink.gif we were able to make a carbon wheel in 2 hours and have it cured in a further 2 hours. the benefits are easy to see. will try to post some photos when i get a chance.
