Race weekend at Sonoma on test day with professional race driver Jason Richardson driving a Porsche 910 Bergspyder before the SVRA race. He took 5th place in this car after passing 19 of the 25 cars in the field. We missed qualifying race and he started at the back .

A fresh 2.0 liter race engine just installed in our 907K is being fine tuned on the chassis dyno before CSRG race at Sonoma in 2019. This engine puts out 235 HP at the crank. We spent half a day optimizing Weber main jets and emulsion tubes finally reaching our peak power.
