If there is one challenge to the beehive revolution, it’s the perception of the masses. While most engine builders and performance enthusiasts know that the beehive works to improve their engines, many don’t realize the true benefits. Some established enthusiasts are confused and concerned that the smaller valve retainer and single spring used in the beehive system are capable of handling the same high performance loads carried by the conventional spring with two coils.
Beehive springs are a precision component just like any part you select for your engine. Using a tech line expert to help find just the right Beehive springs is critical to your engine’s ultimate performance and durability.
“There are some very knowledgeable engine builders who don’t understand how a single coil spring can be better than a dual conventional spring,” stated Thomas Griffin Head valve spring engineer for COMP Cams.
“The fact is the beehive springs, by virtue of the ovate spring shape and a variety of internal upgrades is compatible with virtually any application where a dual spring is used. That includes some engines with mechanical roller camshafts. The key is to review the required camshaft load and assess the aggressiveness of the camshaft.”
The key profile consideration of a camshaft can be denoted in the camshaft profile section. By reviewing the duration specs for your potential camshaft at 0.050-inch lift and again at 0.200-inch lift, the shape of the lobe can be projected. These are the key figures engineers use to determine beehive spring compatibility. Currently beehive springs for camshafts measuring up to 0.750-inch lift are available.
COMP Cams engineers used a Spintron machine to determine exactly what happens with valve spring dynamics at all levels of engine rpm. This high tech sensor was installed after cutting the cylinder head to make room. The Spintron data noted improved performance at reduced valve seat pressures, among other benefits previously mentioned.
