well that's what this list is here for so we all can learn but I think 8:1 is to low for the GSXR motor the combustion chamber is so efficient that you don't have to lower the compression I run a squish of .050 on the GSXR any closer and you are going to have contact how much power do you make at 20 psi?? yes I do run water injection for land speed racing ( 2 to 7 miles at a high boost setting ) but not because the engine detonates because the water injection reduces the thermal stress on the engine and makes it last longer. I just see no reason to waste money on part you don't need. the stock pistons have proven them self's to me,after racing it all year making over......I don't know 150,200 dyno runs.........you tell me would you change anything?
