Did some testing this past weekend with the Ninja and Ninja 2053 pipe, short manifold 14006. Motor had 15 tanks of fuel through it. Ran motor in a 777 SP2. O'Donnell 30% fuel. #6 plug. Track is off-road with multiple doubles, triple and two straights. One about 70 feet and the other starts with a 45ft sweeper into a 130-140ft straight. Lap times were 36-38 seconds. Tuned motor for decent performance, but still on the rich side. Motor still has metal pinch. Used exergen to get a reference point for temps and was at 224*. We got 9 minutes 45 seconds on tank. Car was tech'd at 124.5 cc's. The car had plenty of bottom end and was over-shooting the triple by a good 10-12 feet. Motor ran awesome! Can't wait to see how it runs after it loosens up and is leaned out a bit.
We're going to slap it in a ST-R next weekend to see how it does in a heavier truggy with big wheels/tires. Also curious to see the run times will be in the truck with the larger 150cc tank.
Best regards,
