I got a degree in Mechanical Engineering from the UofI. This was my Senior design project. The car was built by a team of ~10 guys. I did the differential design and the brake design. ~700lbs with driver.
Engine/Drivetrain Modifications:
The Engine is a Honda CBR600 F4i with 20mm intake restriction, Custom (student designed) SLA intake with a carbon fiber wrap. Tuned to ~70HP with a smooth torque curve. The brakes, differential, intake, exahaust pipe and, obviously, the body are all custom. The differential uses the gears from a Eagle Talon TSi center diff and the whole differential can be swapped with a Torsen LSD (we tested the open for active braking reasons).
Brakes
Pedals
Custom 6061 T-6 AL. CNCÂd at ITM: 5:1 ratio
Balance Bar
Tilton 72-250 converted to 72-275 for monetary reasons.
Master Cylinder
Tilton 75-750U Dual set up
¾ Bore
1.1Â Max stroke: Anodized aluminum cylinders.
Hardline
3/16Â Steel hard line from Summit Racing
Single 37degree flare done in house
Speed line
EarlÂs Speed Flex Hose: 24Â in front, 36Â in rear.
Each line is pressure tested to 4,000psi at the factory, our max pressures are under 500psi.
Calipers
