Haraldur Péturson among his trusted team began building the car in November 1998. Davíð Ólafsson was the one that designed and drew up the roll cage. The process didn’t go as smoothly as they hoped. It took them a few tries to get the cage like they wanted to have it but at the end they were satisfied. 

At that time this build was considered revolutionary and different from the other Formula Offroad vehicles. First of all the car would be 900 kg (1984 lbs) or 600 – 700 kg (1323 – 1543 lbs) lighter than their opponents.

They put a V6 Nascar race engine that gave them 425 hp @ 6000 RPM without any NOS. Former crew member Benedikt Eiríksson was the one that took care of the engine. That engine was 100 kg (220 lbs) lighter than lightest engines in the league.

The suspension is made of home-made struts that Davíð built with the help of Renniverkstæði Exa, and had the travel of 30 cm (12″). The vehicle had also an independent front suspension system. With the IFS the kicks would be softer and smoother.

In 2008 Jón Örn Ingileifsson bought the car from Haraldur.  While the car was in his possession, Jón Örn changed the name from “Musso” to “Choir Boy” and replaced the V6 engine with 377Chevy V8 and removed the home-made struts and put 12″ FOX shocks underneath it. 

Snorri bought the car without the 377 Chevy engine only a month before the first race of that season. He and his team tore everything apart, painted then put the car back together to attend the first round. In his possession the car had LS3 GM 427 7L engine. Snorri also upgraded the brake system.

Þór Þormar Pálsson bought the car from Snorri in 2016/2017 where he then became Icelandic Champion in 2018 and 2019 and USA Champion in 2017. After few years of racing on the car he then went on to built a replica of the car and Snorri bought it back from him in 2020.
