Engineering as art

To create something that terrifies its creator.

Beauty is an engineering objective at Kyan Motors.

DI-10 stands for “Dies Irae,” Latin for “Day of Wrath.” Its musical inspiration comes from Mozart’s Requiem.

A short-stroke V10

The 97 mm bore makes room for 41.2 mm titanium intake valves. The 40.57 mm stroke limits how far each piston travels.

At 19,000 rpm, calculated piston acceleration reaches 9,700 g at top dead center.

Pneumatic valve return

The spring is nitrogen.

The intake valves lift 15.5 mm. At 19,000 rpm, the cam profile demands peak acceleration above 8,000 g.

A small piston compresses nitrogen as the valve opens. The compressed gas supplies the return force.

Variable intake

Outlawed by Formula 1’s 2006 engine rules.

Intake length sets when pressure waves return to the valves. Timed correctly, a compression wave helps fill the cylinder before the valve closes.

Hydraulics move five trumpets together on each bank.

About the founder

Joshua Kyan Aalampour

I am a classical composer and the founder of Kyan Motors. My background is originally in physics.

I graduated from UC Berkeley two years early, attended the Eastman School of Music for a master’s in composition, and dropped out after a month. I continued composing on my own and built an audience of about 7,000,000, with a body of work that ranges from string quartets to piano concertos to symphonies.

Alongside the music, I taught myself engineering: first a flat-plane V8, then the DI-10.

This is art to me. All of it.I am an artist before anything else.
