For 2011, Daniel Aeberli of  Shaffer-Motorsports purchased a class 10 car built by Full Potential motorsports in Lake Elsinore for Pacific States engineering.

A build thread can be found at race-dezert.com

Chassis
The chassis meets SCORES’ class 4 and BITD Class 10 chassis. The chassis is fully tig welded 1.75″ x 0.95″ tubing and has 120″ wheelbase and 86″ trackwidth with 19″ front and rear travel.

Engine
The engine found in our car is a direct injected 2.4 L. It uses technology based on GM’s other four-cylinder direct injection applications, but with unique features designed for its specific application. This includes an 11.4:1 compression ratio that helps build power, slightly dished pistons that increase combustion efficiency and injectors with an application-specific flow rate. In production vehicles it achieves up to
182 hp (136 kW) @ 6700 rpm and 172 lb·ft (233 N·m) @ 4900 rpm.
