Those liter-bike powered little open wheel karts...

[makenzie71]

...the ones that look like indy cars.  Do they have a particular name or something?  i've been trying to find some good pics of their suspensions but it's hard to really find much.

im wanting to say they are one-offs but im not sure. ive build a gsxr600 powered unit b4 but not a liter size, ill look. if i find something, ill post it here

they're not one-off's because there's people who race them...well they are 'one-offs's" in a way because they're built by the individual.  Closest thing I can think of is like the skip barber racing school open-wheelers but I think they're powered by 2.4 liter i4's.

Whatever they're powered by I just want to see the suspension.  I know how it has to work just out of common sense but I want to see if there's something different they do that's better than what my mind's conceived.  I want to build one of these things but I don't know why...not like I can race it or anything (no place to race).  Thinking of picking up one of those 2-seater oversized go-karts to invest my time in, instead...with a real motor I could actually use one of those...



One of those things with a 400cc 51hp twin should be fun.  Thing can't weigh 500lbs...

Formula cars. University of Texas SAE builds them for competition.



We have been using CBR600F4i engines for the past couple of years

Here's the last entrant:

[makenzie71]

Alpha is it just something UT does?  The ones I saw last didn't have any kind of college endorsement or anything on them and they had double wishbones up front.  Either way, can you find any pics of their suspensions?  That's what I'm looking for now and it's slow progress on a dial up machine...

I'm sure there are ones that don't, but here is the quip from the SAE site:

"Every May, teams from over 130 universities worldwide converge in Detroit- the automotive capital of the world- to compete in a prestigious engineering competition entitled Formula SAE (FSAE). The program gives students the opportunity to design and build a small, formula-style racecar and compete head-to-head in a three-day, multiple-event competition. Professional engineers judge the car's performance, cost, design, preparation, and safety, awarding overall and categorical prizes to the best teams.

The Longhorn FSAE team is comprised of students from various fields who dedicate their time to the completion of the project. The team is primarily funded through the donations made by our sponsors. We are constantly looking for new members to help maintain and carry on the tradition of the Longhorn FSAE team. If you are interested in helping us complete our goal through sponsorship or by joining the team please contact us for more information. "




Big ones (damaged suspension linkage due to an offending light post base)

That work for ya?

[makenzie71]

works great.  see that one has double wishbones up front and it has the suspension set up close to what's in my mind...I think it would be better for the shocks to be vertical but it would interfere with the rider.  it'll be easy for me to get around it...I think I've going with the off-road kart thing.  Biggest thing I want is some crazy looking suspension.

My best friend did it for Lehigh- there is annual competition in Detroit for SAE. I believe he told me that there are privateers who enter their own fabrications also. From what I hear, it's very expensive and time consuming to  be competitive in any way. Their car is here:

SCCA Formula 1000 cars is what your looking for.

cars are produced by some of the same companies that make Indy cars such as Lola, Van Diemen and Reynard.

Look to the big boy's for suspension ideas.

[makenzie71]

i found some pics of the SCCA 1000 suspensions.  A lot of what I saw had both the front arms linked to a single shock...I just can't see that being a good thing.

Shifter Carts.  Doesn't Rainey driver one now?

[makenzie71]

dude these aren't just "shifter karts"...


(clicky)

That's Stohr's entrant this year.

[makenzie71]

^$35,000 sans motor.  I want one soooooooooooo fun bags....

[sanjay]

I learned a lot of FSAE stuff from UT Arlington, and then I was on the Cal team doing suspension design.  I have some decent suspension pictures from several different teams at trackdays that I can either post or send you, Mak.  Brian, are you on the UT team?

FSAE is limited to 600cc, but you can add a turbo if you want (as long as you design the turbo system).  Some of those cars are faaaaast.

[makenzie71]

I have enough of the front...I'd like to see some rears, especially how the difs are setup...if they even really run differentials (surely they do?).

[bettingpython]

Quaife limited slip differential with fully-machined "Stohr Spar"

[makenzie71]

yeah I just posted all that stuff from stohr.  I'm looking for SAE stuff...scca 1000 stuff is as crazy as indy/f1.

[sanjay]

Argh, I think my CD with pictures is packed in a box (I'm in the middle of moving).  Here are some pictures of Cal's car, and I'll dig some more up in the next few days.

If you want to do off-road karts, there's also a SAE competition called Mini-Baja.  I know absolutely nothing about it, so Google is your friend on that one.
