Huh??? My brothers 9lbs boost it 800 174 apparently made his stock 2021 doo turbo look pretty silly.
Not all systems create the same power hp/1lbs of boost. This has been my point for years.... But yes a Boostit @ 9lbs running against a stock turbo doo should annihilate it as they do make greater hp/lbs of boost probably an honest 9-10. The new poo based on my poor boy calculations it is probably +|- 5hp/lbs of boost maybe less. If I'm wrong please correct me as I'm not the smartest guy on here.
The 3" is about the worst track you can put on a sled. Just trenches and is very heavy.
2.75" is also a 3.5" pitch vs the 3" pitch of the 3"
