On the ball. At shannonville in the summer between events 4 and 5 vlad’s butterfly bolt snapped and flew into the throttle body because of a design flaw in the shape of the Greddy Intake manifoldhe had purchase for his setup. Later in the season, Hideki of Team Toyo verified that there was a recall in japan for Greddy SR manifolds.
That SR was running strong at the time on an all stock block. And after doing events 5 and 6 on his “new” block from U2n its still running fine as it sits for the winter season.
