Buddy and I tested F7 Patriot yesterday.Set up porta tree for 500ft. Driver weight was 170 it was 43 degrees outside. This sled was not studded but had high profile track. There was no oil in gas tank and put new belt every 2 runs also gave proper cool down. Friend was very disappointed with times. I know this sled is not studded but he was still getting good hole shot.I heard yesterday the way they were getting 5.300 or 5.400 at haydays they were staged deep like 6ft back and they were PROs sleds that is a good running start.The best time of the day was 6.447 at 78mph. Remember this is box stock. I think this is a very sharp looking sled but ETs need alot of work yet. Will be testing with D&D set up next time. Have 3 more F7 to test tomorrow if it don't rain.
