Raced my buddy's '07 F1000. He has a boat load of work done to his sled.
D&D y-pipe, pipe, can, heads, porting, clutching, boondocker, O2 wide band.
He has 204 1.450" studs, I have 168 1.325" studs.
We raced four times so far. I'm sure we will race more.
Three of the four times he got me out of the hole but only got me by less than 2 sleds lengths on top. Which probably equates to with all the work done to his sled. About $1000.00 per sled length. One time I got him out of the hole he couldn't go by me and I got him by a sled length. I have only 600 miles on the sled.
I'm sure after 1000 miles I should gain some more speed.
