HAS THIS EVER HAPPENED TO YOU?
NEW! Redblockpowered valve spring kit, available here: https://www.redblockpowered.com/shop/p/beehive-valve-spring-upgrade
Made for B230s, the Redblockpowered Beehive valve spring package saves almost twenty grams per valve improving valvetrain stability and RPM capability. Spring pressures are not terribly high making these a good upgrade for stock or close to stock RPM limits (less than ~7000 rpm or so).
Available in high and low lift form, and includes retainers.
Two installed heights available: 37.5 mm and 36.4 mm. The latter offers slightly more seat pressure at the cost of total available valve lift. Beehive springs should be shimmed to as close to bind + 1 mm (for clearance) as possible for optimum performance.
Spring force:
62 lbs @ 37.5 mm
160 lbs @ 25.5 mm
Bind height: 23.9 mm
Always check your installed height and coil bind!
