Matevos Isaakyan took his first win World Series Formula V8 3.5 win of the year as he ran longer than the opposition, leap frogging them in the pit lane during the second race at Spa-Francorchamps.
The Russian driver had started from fourth but dropped back in the opening lap. From there he extended the life of his tyres in the initial stint, stopping on lap ten and coming out ahead of Rene Binder.
Once again it was Pietro Fittipaldi who made a poor start, dropping two places off the line. Fortunately for the Brazilian, this proved to not be as fatal as it was on Friday, taking second place before Eau Rouge.
Fittipaldi would fight back, taking the lead from teammate Binder at Les Combes and building up a one second gap by the end of the first lap. Elsewhere, race one winner Alfonso Celis Jr, jumped two places to chase teammate Diego Menchaca for third by the end of the opening lap.
As the leaders spread out, battles would continue further down the field with Nelson Mason the first to dive into the pits when the window opened.
It was all action as Fittipaldi came in, though as the Lotus driver went to pull away, he stalled the car losing 19 seconds. Celis had made the biggest gains, ending up provisionally second with only Isaakyan left on track.
The SMP Racing by AVF driver had benefited from the mayhem though, maintaining the lead and pushing Binder and Celis back one position. A three-way fight for the lead would eventually conclude with Isaakyan using his cleaner tyres to open up a gap to Binder.
In the end, Isaakyan took the flag by over three seconds with Binder once again settling for second place. Celis meanwhile truly enters the championship battle with a strong third place as his rivals faltered.
Roy Nissany took fourth on the penultimate lap from rookie winner Menchaca as Fittipaldi came home to a disappointing sixth, though will take solace in his late overtake of points rival Egor Orudzhev.
The top ten were rounded out by Yu Kanamaru, Mason and Damiano Fioravanti, while a troublesome race from Konstantin Tereschenko and Giuseppe Cipriani saw them round out the field.
