So it sounds like the stock cdi is running the ignition, and the ms is running the injection, pretty much completely independant of each other. Are you running the stock wiring harness from the quad,...

Actually I was on a team that showed up to design without a car once, and we were not disqualified, no surprise we didn't do very well though. Things really didn't improve much when the car showed up...
Thanks for the response Jetser.
I figured it would be something like that, which is what I was afraid of since I have no mill or lathe.
Anybody else?
How do you know how many teeth are...
Hoping to get a bit of advice from the teams who have run a Yamaha WR450 engine. I'm scheming to put efi (microsquirt) on one in a bike, not fsae car that's why this is in "off topic"
What did you...

Question for RMIT I've seen many mentions of having not changed anything internally.
Not 100% sure on this but it seems that the main difference between the YZ and WR internally is the cams....
Chris, I would guess that the judge was looking for a response along the lines that in the rain you use less front bias because you have less weight transfer due to lower overall grip.
About the...
Not really relevent to this thread, but it occured to me while looking at that FRIP setup that it isn't actually a mcpherson strut suspension, but an A-arm suspension rearranged to fit where a...
My favorite was the request for a five horse outboard motor at the 04 comp.
No usefull information to add to the thread, just sparked a memory.
I was not on the team when Michigan tech did the backwards motors (they did it for like 4 years) but I have seen and studied the cars a bit) They ran the motor backward which required:
Modify the...
I agree with Cook, you can still stop the car with just front brakes. I maybe wouldn't count on it for a track car, but in our situation you would have plenty of time to safely stop the car with only...
I may have just had a minor revelation thanks to your prof and your post. I'm starting to think he's right.
What all of the books say is that the roll center needs to stay fixed relative to the cg...
Did your prof give a reason for keeping it fixed relative to the ground? Sounds like HE couldn't come up with a good arguement. Basically he said the reason it should be done his way rather than...
I used the output shaft torque, that would be required to smoke the tires with a coeficient of friction of 1.5.
Then I chickened out and made the mounts stronger. Lots of vibration going on there...
We use the same as CMU Racing mentioned. 1.25 inch bore on the bearings and 1.5 for the seal. Far oversized in my opinion, but they are big enough to get a decent sized stub through, and you can go...
Warning! I'm about to ramble:
Pat mentions that a little scrub radius might be a good thing, because it lets the driver feel the car. It seems like the moment arm caused by scrub radius...
I thought that if one end of the car has no roll resistance then all of the weight is transfered on the other end. There can be no weight transfer if there is no roll resistance, since the weight...
I have no idea how much kpi is acceptable and how much isn't, but one thing that was eye opening for me when I was debating the same compromise was when I actually calculated the camber effects of...
Interesting, after staring at it for a while and scratching my head, I think it's pretty much a way more complicated way to get the same thing as a de-dion (probably spelled wrong) would get you,...
SVSU had it in 05, and I think Adelaide (probably spelled that wrong) had it on at least one car. It would be nice to do gear drive for packaging reasons, makes the back of the chassis much simpler...
Just realized that what I said actually pretty much agrees with what TG says.
KURacing, I did look up the properties, it is almost exactly half as dense and half as stiff as steel. It also has a really high yield and ultimate strength. Which is great for keeping a wheel from...
Are your stub axles titanium also? What alloy are you using?
Why titanium?
Seems like the density and modulus of elasticity of most titanium alloys are both about half of steel. Since we've...
Pat, good points. Sounds like the result of frustration from looking through a bunch of sub par design reports. However, it looks to me like people are wondering what the smallest font they can get...
