So after tuning our engines old Motec M84 for our new engine, it pumped out 501 whp and 471 lb/ft of torque. We were pretty impressed as this engine is built for a long life instead of peak power. The championship-winning engine circa 2010 only put out 440 whp with the same displacement so we are doubly impressed. We feel that with bigger diameter primaries for the headers there is at least another 10 hp to be found and newer technology better cylinder heads would unleash another 10-20 hp. However, we are quite satisfied with our results.
The Falken S13 can probably next be seen at the Spring Gridlife at Gingerman Raceway in June!
