thank you!
This is a bit heavier than I initially thought. Including a standard 25g spring retainer we're talking about 363g or thereabouts. For a non-matriculated type analysis like this I would cut the spring weight in half, so call it 323g. For a typical DC43 type cam with nearly half an inch of lift and what I'm sure is a fairly hefty acceleration rate, I'm coming up with 104NM seat force (77lbs) and 341NM (252lbs) at 7500rpm, add 5-10% for the stasis fudge factors and it appears Eibach actually did a great job with those springs. I remain shocked though, seems like a lot. thanks again
