    We mostly take the sled to the field or track, do some starts and keep turning out the red caps until the engine bogs and then turn them in a click or two

    There are some aftermarket plastic rave caps out there that are set up w/a little button type thingy in the center. when the raves open you can visually see them pop so you can sync them on a stand.  Past dyno info I have seen showed that 6500 is the peak HP wise # for them to open.  Thats what I believed for a long time. However first hand info given to me by lets say A Hall of Fame Skidoo/Legend/Drag racer said, nope hold them shut until 7000/7500 cause that helps the sled gate harder.  1 218-334-3388 may still be a valid # to find these caps I speak of. ( Its whats printed on my caps.) Good Luck.  MMR
