[Fot] Valve spring pressures

[marty sukey]

Hey all. I am trying to decipher some power loss weirdness I was experiencing on the dyno Thursday over 7000 rpm on my Spitfire. One of the paths I am going down is valve spring pressure at full open. I know its cam dependent but what are some of you other Spitfire folks running so I can get some ballpark ideas. Heading to PittRace on Wednesday.

Thanks,
Marty
