Lol its called grudge racing... and if if my 10 super runs 5.8 5.9 on a good track why wouldn't a 16 super be like I said in the range of 5.5 5.6. it's only 2 tenths under what I'm runing now and I go from a 521 to like a 620 or something like that 100 cc = 2 tenths all day. I'm just gonna make the biggest cub possible in stock cases witch is a 16 cuz after that 18 is only billet cases and the super cub. I'll let you guys no or we can race and find out lol
