Has anyone on this board measured and confirmed the reported %15 increase in spring stiffness with the new springs? I know very well that they have new part numbers but numbers are just numbers. I want to see test data!

I know importreview did a thorough test on valve springs but he only tested one TypeR valve spring with no mention of year or function (intake or exhaust).

Thanks,

Sure, nice thread, but it didn't answer my question. I spend half my day searching through the vast Honda-Tech archive. I think I have read everything here on this subject but I haven't found my answer.

Thanks anyway
