damnn!!! over 430hp on 8lbs??!!?!?... makes me wonder what I am going to make on 8lbs. I'm almost done with my build. I have a fully built sleeved 11:1 k24 with a z1 head. stock cams with supertech springs retainers and vavles. I went with a bwr sidewinder and a GTX3582r. I just installed my MVR today I put the 8lb spring in it. Wonder what it will make and how it will feel on 8lbs. what do you think?
