One of the last 1ltr Diasios Built. Well Sorted. Originally Developed and Track Driven by Chris Diasio.
Fabcar Tube Frame Chassis. Fabcar was Builder of Contract Porsche 962’s. The Chassis is basically infinitely adjustable to your particular driving preference. If you prefer a bit of oversteer or understeer, or want to set up for the corner leading to the fastest straight, you can just dial it in.

YZF 1000 Engines make 150HP Stock and 160+HP on Race Fuel. (At the Crankshaft)
Redline is 11,800 rpm. However in the interest of engine longevity, I always short shift at 11,000. It's on the pipe right there anyway. No Trophy's in HPDE.
The sound at 11,000 is Glorious, like old school F1 or Indycar.
Current installed Engine is Higher Compression, running 110 Race Fuel. (Approx 20 Hours on This Engine) Pulls Hard! Yet idles like a kitten. This engine was built by Billy Wiese, "A noted and accomplished AMA tuner", now in Florence TX. Billy founded WRW Racing, formerly in Houston.

Original Putnam Park Livery. I would describe the overall presentation as Very Clean-Nice with Attractive Patina. Never Any Accidents. Always draws a croud when you unload. It has been cleaned and fussed over after every track weekend. Stored Inside and Admired. The Custom Paint and Wrap are Striking. I never had the heart to change it. As a result, there are multiple scratches and imperfections in the body paint. The Chassis has the original light grey powder coating that has been touched up many times over the years.
Selling because we have too many Track Cars. Building a Caterham Track Car right now.
