Not really. Considering it will be very safe


BTW, where did you get the donor engine from?
 
Ok, here is what you do : Go to a junk yard, then find a good pair of giveaway tires, they must have some tread, and preferably summer tires. Take them. Put them on the ducky and you win! :D

not a bad idea. we have considered it. ill see what i can do in the next month or so. anything but those crappy trailor tires. if we do go with those however, we did find some pretty beefy and wide ones. so it wont be too bad
 
I haven't personally been in an FSAE program, but I've followed my friend's team for 3 or 4 years develop two cars, and he's currently at a different school working with another team. They went to Detroit twice, placing very respectably the second time. Interesting stuff, but I would just want to lap it, but that is only a very small portion of the total scoring on the FSAE cars.
 
I have driven some like this, with similar horsepower and weight:

430LBS

90hp

Same site I linked you to before has everything you need

It had a 01 CR500 engine on it, thats kind of why I asked why you didnt use a 2 stroke. The engine weighed about 75 LBS and was water cooled. The top speed was limited by the gearing and how much room you had, and most of all, how far you were willing to push it. I have heard reports of people doing NOS injection and doing 120+MPH

But im sure you will sort most of the problems out your selfs, fell free to PM me with any info on these things

its a very involved sport with the University here in Madison having a nearly quarter mil in research and development. we are doing it ourselved in a semester. more than anything its an excuse to build this thing :) good luck to your friend this year!

a lightweight engine would be nice. ours weighs 169 lbs without everything required to run. the choice to use it was based on the fact that it was free, and almost gauranteed to run right away. the gearing on the bike in stock spec tops out in sixth at 115 mph, but we are changing the final gear ratio. im not sure what to exactly yet, but it will be saomewhere in the neighborhood of 1.25 times longer than the original. i dont think we will be seeing the far end of that band. the school will not condone it on their insurance policy. and the kart will be the property of the school anyway :(

thanks for the info by the way. i may very well be able to use you. stay tuned for tech questions as we start putting it together. 👍
 
March 2nd 2007

today we brought the bike frame inside form its snowy burrial out in the project cage. its been sitting there for four years and was way at the back. we had to move a riding lawnmower, an industrial blower, a push mower, a mini bike, and a GSX-R 750. all of which were under 3 feet on snow. :ouch: we then detached the front dual brakes and fluid resivior to transplant to the kart. after that we took apart the rat nest 20 year old wire harness and modified it for our use. we bypassed some of the safety leads like the kickstand switch and the neutral switch. we kept the clutch switch though. it may be nice to have. minus the lights, turn indicators and the speedometer and you have our new harness. we taped it back up in orange electrical tape.

the turbo was also disassembled so it could be reconfigured. we need to rotate the oil syestem 90 degrees. as it sat, the oil feed port and the dump port were parallel to the ground. we want them perpendicular so the oil can feed in the top and drain out the bottom. an oil line was tapped into the oil filter housing to feed the turbo. the dump will drain into the existing oil fill cap after we tap the center of that as well.​


as it sits..





destruction under way.


the brake calipers


the brake discs were on there good. i didnt have a rubber mallet to pound them off, so they remain ther for now


tracking wires


all sorted out 👍


testing connections and resistance.


me fixing a bad connection


all taped up and ready to be transplanted


turbine wheel


turbine housing


tapping the oil filter case


prepping the oil fill cap for a tapping too.
 
Did you guys keep the tach?

Its a pain in the arse to get another one or even a new digital one at that. Everything seems to be going smoothly for you ( to easy if I say so myself) and it looks like you are in good shape.

When (or if) you finish, we (I speak for a lot of people right now) Would LOVE to see some videos of it running

we did keep the tach. it will work perfectly. it even matches the new speedometer we are purchasing. we ordered a racing seat, a wastegate, and a BOV. the engine is close to running :D

things are going pretty smoothly. i havent spoken of our set backs. we are doing really well at the moment. our frame is being built down the hall from instead of at a company. some students in the welding class took on our project. thats awesome for us because we can document that too, not to mention fit things like the seat and engine as its being built.

i will most definetly post lots of videos. as soon as i learn how to upload them that is. i will look for a tutorial around here.

(i added lots of pics on the last page)

here is the team shirt!​

What are you guys doing for body work?

Fiberglass?
Cardboard? (believe me, its been done)
Paint?

Or are these thing not even being considered right now due to the time


EDIT double post, mods please merge if you could kindly do so

the body will either be a thin plastic sheet or a thin metal sheet simply rolled around the nose. (refer to page 1; the black body render) i think thats the only body work we will do. we are gathering sponsors slowly, so we may need to make more panels for more stickers. so far we have five contributors.

krylon matte black my friend, all of it :D

i checked out that site you linked. its very neat. and quite usefull. we may order our racing harness from there as well as a fuel cell. if we can make it fit that is..
 
Just to let you know, they are based in red bluff CA, so It might take a while to get to you. Also, I dont know what you guys are doing for seats, but you might want to check out their classifieds and look for a nice kirky seat.
 
well its halfway through april and we have like a month before this thing is due. none of my other teammates seem to want to work so progress is slow. we received our steel and the frame is being built as i type this. i will get some pics. in the mean time here is a render of the kart in its current state. i have a feeling my team will realize we need to work hard to get this done and i will have lots to share with you guys in the upcoming weeks.

this is what i have done in the past week or so.

modeled intercooler, and fuel cell, and racing seat. put it all in an assembly. we were supposed to have the new turbo exaust manifold fabricated by the guys that are doing the frame, but they decided they dont have the time. that is a huge setback considering none of us have great metal working skills. its on schedual for completion tomorrow during our 4 hour class.​




as you may have noticed the intercooler is no longer going to be top mounted. these things have a way a changing, you know? :) we had clearance issues with the turbo and the frame which changed everything. new header, new mount locations, and new fuel cell. thats it for now, but stay tuned for some real action.​
 
Wow that's one of the cooler things I've seen, best of luck to you, I hope you get it done and it works. I can't wait to see some videos of that thing.
 
I'm not sure if this will affect the way you build this thing but here it goes.... From my experence of gokarts it looks like the front wheels need to be moved forward about 8'' to 10'' because it looks like there would be a problem with the location of the steering hardware and then widen it by 6'' to 8''. And also have the driver leaning back more like an F1 car.
 
i appreciate your concern for our design, but that problem will not plauge us. we will use a shaft to a pulley set at the front of the frame and use tie rods to pivot the knuckles. every mechanical component works at a right angles and linear paths so binding wond be a problem. i will post pics of the steering system as soon as its modeled. :)
 
Looking good 👍

I hear your pain with a team that isn't really putting a lot of effort into the project because just last week my design project was due and we had to finish it in a series of all-nighters, but I'm sure you'll get it done :)
 
How much clearance is between the top of your head and the top anti roll bar?! I'd hate to go over a bump.

not much, but that body is modeled after the largest member of my team. he is at least twice my size. so i am not worried. (he has about 2.5 inches clearance.

Looks mire like a formula SAE car to me...

Except the Turbo part. Yikes.

thats what its supposed to look like. 👍

Is it going to have one rear axle? Essentially a locked diff! Yikes!
Click to expand...

our thoughts exactly, but we dont have the money for an open or limited slip diff, so this is what we got. its gonna ride like a bucking horse, but it will be really fast. :sick:
