Give the guy a break. He's not ready for a full blown post so he's just putting his toe in.
There are lightweight master cylinders fittd to many production cars. Try looking at clutch master cylinders eg Hyundai.
Frankly I find those numbers hard to swallow. I suspect your chassis wasn't even made of cheese. (I'm milking this for all its worth.) In fact your whole post stinks like a rancid Limberger.
If it kicks back on the starter the spark is early (advanced). If you hear a feeble pop without any acceleration of the starter, the timing is very late (retarded) and you should try moving each of...
Sounds like you have fuel and spark but the spark is not happening at the right time. Are the spark plug wires going to the correct cylinders?
Orange spark is not ideal. Blue spark is better.
Looking at your diagram, it appears you already know exactly where the spring centre is.
That would require the Roots to be sized/geared to less-than engine displacement ie negative boost when turbo is not helping - not so good for scavenging. BTW, the engine would need a scavenge pump...
A restrictor with downstream throttling would create the possibility of inserting a large plenum between restrictor and throttle, enabling short term power capability in excess of the steady-state...
Z, not sure if you noticed, but the 2012 UWA car is in fact your "Z-Bar Concept" drawing shown at top left. The differences are : "Centre-pivot Leaf Springs" replaced by the aero undertray acting as...

Quite the opposite of what Z proposes.
Agree with all that Tony, and even the spidery truss fron beam will have better camber compliance than a double wishbone.
After reading a good chunk of this thread, I am amazed by one thing. A couple of posters have stated that beam axles are OK - on smooth roads only - and no-one, not even the proponents of beam axles,...
You may not have intended it this way Claude, but this line of argument is dubious because it smells like "You don't have success, peer acclaim, lots of experience etc therefore your views carry less...
They are usually the wrong ones.
I can't think why it would be different for centre lock nuts, but standard practice for normal wheel nuts is LH thread on LH side. I have experienced wheels coming loose on cars a couple of times and...
For those (including myself) who don't want to struggle through the maths.
The most frequent1y analysed aero situation assumes a 2D system ie no nett force acting perpendicular to the vehicle's...
So you decided the transmission efficiency gain would be sufficient to make 45kg unsprung weight a tolerable compromise. On the other hand you don't know what the transmission efficiency gain is and...
I need to repeat my original question. Has any of your team studied any thermodynamics? You need to take an analytical approach and many of your questions and "wierd ideas" can be quickly eliminated....
Has any of your team mates enrolled in a thermodynamics unit yet?
If you want to cool something that is already hot (water or oil) you cool it by transferring the heat to the cooling medium...
Although I would also side with the naysayers, as MechanicalChris says "Put it together and measure it". I have been surprised many times by the accuracy of Japanese bike engine components.
Does anyone have information about the composition of the E85 supplied at FSAE Australia? Caltex states that the proportion of Ethanol can vary from 70% to 85% depending on season. If a team tunes...

You are misunderstanding Coastertrav. You can rotate the turbine and compressor housings about the shaft axis to any orientation you like and still align the centre housing within 15 deg of...
