540 Vic Jr, 2in. vs none. I saw no difference with a 4 hole or combination. Regular 2 inch open.

Identical engines one with 4 hole one with super sucker 4 hole.
SS made +6hp/+12tq, that engine consistently pulls 50 rpm more than other. Does it make a difference in speed, prob not, but mid range cruise (where I spend most time) is probably more efficient based on tq increase.
I'm going to replace standard spacer with SS in the spring to verify results.

No, the better blue line is spacer and is making more power. The printer was running out of ink so the one line is traced over to darken it.
