now the 5.5 is were im getting the best fuel but there is a notable low end power loss " i'll save that for the big tracks"
pipe= rdlogic's mid range pipe long header
going to start testing pipes and headers

"this weekend"

i will report findings and model
running the blackmagic case and head with mamba x2 internals
yea thats what i noticed the smaller restrictor i think caused me to be on the trigger a little heavier than normal cause with the large one(restrictor) and a jp-2 pipe ive gotten 10 -101/2 mins on the mamba. so this weekend ill be using large restrictor i run on a large track need all the help i can get:smile
