so how did each feel on the road? Dyno's only tell part of the story
. how did each feel seat of the pants. I think I would be happy to see 80/90 with stock heads. Do you think I could do it with the 21's?
Stock heads with the TW21 will produce similar results. As one dyno I posted showing my run with mildly ported heads and a 2001 Ultra with no headwork. Both produced mid 80' HP, high 90's TQ. But more important than numbers, the TQ began down low and climbed very nicely.Mtclassic said:so how did each feel on the road?
