I won the 11.0 class with 150+ weight added to the trunk to slow it down after trying Q16 fuel which made it run .10 faster than normal. That fuel works but had to up the jets in the 1050 dominator from 98 to 102. That fuel cost alot more but it makes the 455 run consistent. 1.479 60ft times every time. Stock sealed power pistons and a big 7XR Kenne-Bell cam. Racing is good with this fuel.
