I did it guys i ordered the Shark 9 today at amain for 424.99 with a 25$ coupon i got it for 399.99 WOW

. I cant wait to break it in and run it this year in the North Carolina champ seires. I hope it got power like my c6 i well have it as back up this year as i only have like 5 gallons on it. It well be ok to run 20% or 30% with stock shiming right? I may try 20% this year to get more runtime out of my motor not sure thought. Thanks Speedyrob GO RB 2010
