The Reasons• Fastest car on the track.

• Virtually assured a trophy of some sort.

• Might get crushed!

• We’ll get at least 15-20 seconds of fame.

• We Could win!

• Comparable amount of work/money to another XR.

Fastest?…. Show me.• Mathematical Simulation

– Track divided into curves and straights.

– Assumed maximum lateral g’s on curves.

– Assumed maximum accel/decel on straights.

Fastest!• A gap of more than 11

seconds.• Gap of our best lap vs

overall best lap in July: 9 seconds.

SCIENCE!Behold the power of

But what if…• …we crank up the boost

on the XR?– Even doubling

horsepower only yields a 4 second improvement.

• …we improve the handling of the XR?– Raising the skidpad from

.8 to .9g’s gets you only 2.4 seconds.

Watch and BE AMAZED

We’ll get some kind of trophy!

• Even if the car completely craps out we’ve got the Banned Technology award wrapped up!

We might get crushed!• Validation that we

outperformed expectations.

• Most awesomest story to tell friends, family, acquantances…

• A smashed fan would look awesome next to banned technology award.

15-20 seconds of fame… at least!

• Increased value for remaining 14 fans!

• Endorsements! (read:Brawndo!)

We could win!

But Brian… isn’t it all a lot of work?

• Not really:– Minimal performance

mods to the Civic. Mostly anti-roll bars.

– Motor/fan module can be built separately.

– Vacuum manifold hung from A-arms.

– If all else fails we can still drive the Civic.

…and you spent how much on shipping?

• Much of the fan money is recoverable (Al scrap is $.50/lb at Star Metals)

• Other Expenses similar to new XR– Cage (cheaper!)– Wheels/Tires– Used motorcycle motor

($100 on craigslist).– Manifold materials.

The Reasons: Recap• Fastest car on the track.

• Virtually assured a trophy of some sort.

• Might get crushed!

• We’ll get at least 15-20 seconds of fame.

• Could win!

• Comparable amount of work/money to another XR.
