Cause there are no restrictions anymore and everything works properly Link to comment https://www.sau.com.au/forums/topic/453567-valve-float-next-step/page/4/#findComment-7553389 Share on other sites More sharing options...

GTRPSI Posted June 20, 2015 Share Posted June 20, 2015 Springs are supposed to have a installed seat pressure. Has anyone checked the Jap brands at seat VS the others at seat? Most people simply fit them without looking/thinking twice. You supposed to know your free length which varies when reseating valves then check it before fitting to each valve individually, its part of blue printing the head. Dont forget to check for coil bind depending on the lift and reinstalled height. To break a spring may point to a scratch on one leading to a fatigue crack or over rev or a softened spring. Now that leads me to question if the Jap springs are good when new but may be softening with repeated heat cycles.....food for thought.....

r32-25t Posted June 20, 2015 Share Posted June 20, 2015 Yea I stated earlier that the reason we took them out was due to the fact we couldn't get the correct seat pressure without having a bind problem even with just using a pon cam Link to comment https://www.sau.com.au/forums/topic/453567-valve-float-next-step/page/4/#findComment-7553645 Share on other sites More sharing options...

Girorostar Posted June 22, 2015 Share Posted June 22, 2015 Hey guys. Reading through this thread had made me wonder. Couple of months ago i dyno my car and it wouldn't make any more power above 17 psi. I thought i hit a massive restriction. But now i'm thinking if it's valve float. At 16 psi it made this. And at 17 psi it made this. Is this valve float? Thanks in advance.
