Crower's New B Series VTEC Race Core
Crower is pleased to introduce a new high performance core for the twin cam B series VTEC engine platform. This new core features bigger secondary and primary lobes for unlimited spec and the ability to run outer lobes only, grinding away the mid lobe. The fact that Crower grinds the cams in house gives you the opportunity to mix and match profiles for your particular application. Other possibilities are bigger idle lobes for increased performance on the bottom end, through the switchover point and beyond 10,000 rpm on the big mid lobe. This core is for serious race applications. Prices start at $750 for catalog grinds listed below, and $850 for custom cams with outer lobes only.
