“Beehives Done Right” by Dan Ruddock also fits T4 Price: $250
|
•Designed to work optimally when used with Porsche/ratio-rocker style rockers. (adjusted
at pushrod end). Can also be used with stock VW style rockers.
•Intended for high performance street/strip car, bus or buggy
•Installed height 1.700 (the extra spring room is provided by the special extra offset
retainers)
•Max actual measured lift is .550" (more than enough for a high-performance daily driver)
•110 lbs. seat pressure and 295 lbs. full lift pressure
•Oval shaped wire allows more pressure without a loss of spring travel
•Extra-long valves are not needed
•Kit comes with everything seen in figure 1
The main advantage of “Beehives Done Right” is better performance.
Here’s how:
“Beehives Done Right” the over the nose spring pressure of dual springs without the need to cut and therefore weaken the guide boss. “Beehives Done Right” also fit the VW head with no modifications and reduces the possibility of a dropped intake valve guide. In addition, extra-long valves are not needed. Having standard size valves maintain the original geometry that the rocker was designed for.
“Beehives Done Right” have the same or better “high rpm performance” of your typical “5 coil HD dual spring”, but they do it with less seat pressure (110lbs) and slightly less pressure at maximum lift (295lbs). This is possible because this kit’s 4140 heat treated steel retainers are as light (12.5 grams) as full-size titanium retainers. The top half of the spring (the part that does most of the moving) is also lighter than the old dual spring setup. I ran my 1835cc 48 IDA 42X37.5 test engine into the 7100 rpm limiter many times without any signs of float and when I tore down the heads, the valves were still sealing well and had no signs of seat hammering. Although you should contact me with your valve train combo and intended usage for a recommended RPM limit.
A good set of dual springs will have an interference fit to keep harmonic vibrations under control. The downside is that the friction from rubbing increases oil temperature. On a beehive spring, the different size coils resonate at a different frequency for a harmonic canceling effect with no extra heat. The long term cost of “Beehives Done Right” thus becomes very competitive against standard dual springs with titanium retainers.
Use the correct spring for the application. The reduced number of coils in the 4 ½ coil 650 spring (with the same free length) bends the wire more and shortens the life of the spring. A single purpose drag car can afford the shorter life of a 650 spring, but daily drivers cannot. “Beehives Done Right” has 6 coils and will last longer than any 5 coil HD dual spring on the market. See figure 2 comparing the beehive (center) with a standard HD single spring (left) and dual spring (right).
On T4 engines the guide boss will need to be cut down to fit the I.D. of the Beehive spring. This will leave plenty of support for the valve guide.
For T1 and T4 engines with stock style rockers, you will also need to shim out the rockers about .060" add elephant style feet and clearance the rockers so the screws turn in deeper into the rocker. Screw the adjuster in as far as possible still allowing room for adjustment and swivel movement and then lock the screw. Then make pushrods to fit. This link is an example of what needs to be done.

Others have sold beehive kits with springs smaller than the VW 1.25” outside diameter. Their very small top to bottom size differential negates most of the harmonic canceling effect. “Beehives Done Right” are the full VW diameter and fit the head perfectly.
Will not work with CB SINGLE GROOVE SUPERGRIP VALVES.
WARNING: Due to inconsistent advertised rocker arm ratios, it is MANDATORY to check total lift and ensure you have a minimum of .060" from coil bind before final engine assembly.
Sorry my cost have gone up. The hike just maintains profit margin and could go up again if things keep going as they are.
