As most have said your over springed with a big dia. triple, a smaller dia double with the correct spring rates are possible but you already have your springs.Thanks,
I hear you on the over revving. I’m going to put a 7600-7700rpm chip in the limiter and shift it at 7200-7300 to make sure it doesn’t overrev, but I would like to stay off the limiter on nitrous for sure.
Are you saying that I can and should drop the installed height down from 2.1” with this spring, or that I should change out the springs?
I always ASSumed that the more clearance you had from coil bind the better? I learned something new tonight. Thanks for this.
I had no idea that I had way too much spring in this thing. I’m not a fan of using stiffer springs than necessary, and I know that a lot of people err on the stiffear side, which is just more stress on the valvetrain and robs a bit of power.
The spring info all manufacturers list are a starting point and a way to verify there spring rates ,coil bind, etc. IMO start with the coil bind 1.130 add your lift .836 and then .050-.060 for spring gap which comes up with your installed height which is how most quality spring manufacturers suggest to do. Set up at those gaps at full spring compressoin the gap would be in the middle of the spring and the ends will slightly be touching. Better spring control , when your running big gaps in the spring it could lose control of the valve easier causing spring surge/bouncing.
I dont know your cam supplier but they should have given you a spring rate or required spring pressure to control the specifics and their lobe design.
Is this a stainless valve or titanium?
You will likely need the other keepers as well as Scott has stated if using these spring which should be done before any height measurements to set up springs.
