RACING VALVE SPRINGS 944 / 951 / 968



944T (951) / 944 8v LR RACING VALVE SPRINGS:



These are the springs of the future for the high performance 951. This spring is currently being used on racing 911 engines using 2" valves, turning 8,000 RPM and running 25-30 pounds of boost. These high quality springs are made from silicon chrome with vanadium and are heat treated, shot peened, polished and low temp stress relieved.

The Spring Kit includes 8 Inner and Outer valve springs, 8 spring cups and 8 Moly Retainers. You can also choose the Titanium Retainer option for additional valve train weight savings.

These Racing Springs have a installed height pressure of 145#. We tested a set of these springs after "2700" miles with a loss of 7#'s of installed height pressure which translates into a mere 4% loss.

We tested a set of Genuine Porsche springs which have a installed height pressure of 130# and after only "500" miles had a loss of 10# of installed height pressure which translates into a 8% loss.

Genuine Porsche Spring after 500 miles = 8% loss.

Lindsey's Racing Spring after 2700 miles = 4% loss.

RACING SPRING 72.3 grams 19.0 grams


We currently have 3 different spring rates available for the 944/951 8v heads. 140#, 150# and 160#. We do not recommend going higher then 140# on a hydraulic lifter. We typically use the 150# kit on solid lifter cam set-ups and 160# if a very high boost and/or RPM solid lifter application.

NOTE: You must use our spring cups. They are custom for these springs and are designed to set the proper installed height and eliminate the shim. Do "NOT" install a shim under them.

944 8v LR RACING BEE-HIVE VALVE SPRINGS:


This is a Beehive shaped spring. This is a single spring arrangement with replacement spring cups and chrome moly.

The Beehive style spring has several benefits. Because of the changing spring diameter, the harmonics associated with a straight spring are not there and they don't need a inner spring to cancel out the harmonics of the outer spring. The wire is actually oval shaped versus round. This allows for more lift before coil bind and the spring is thicker where it is usually prone to cracking making it more resilient. The smaller retainer end of the spring allows for a smaller and lighter weight retainer. The moving mass of the spring is lighter since that's the smaller end. Without a inner spring, they run cooler because there is no friction between the two. This can aid in cooler oil temps.

These high quality springs are made from silicon chrome with vanadium ovate wire (oval) and are heat treated, shot peened, polished and low temp stress relieved.

This "Beehive Racing" spring has the following specs:

115# Seat Pressure at Installed Height of 1.520".
240# Nose Pressure at 0.500" Lift.
Coil Binds at 0.930" Lift.

These high quality springs are made from silicon chrome with vanadium ovate wire (oval) and are heat treated, shot peened, polished and low temp stress relieved.

This "Beehive Racing" spring has the following specs:

80# Seat Pressure at Installed Height of 1.490".
202# Nose Pressure at .400" Lift.
235# Nose Pressure at .500" Lift.
245# Nose Pressure at .550" Lift.
Coil Binds at .600" Lift so max .550 lift cam recommended.

This spring works well on NA application or Turbo'd up to 15 psi of boost. If going higher in the boost, we go to the next set.

"Beehive Racing Plus" Spring Kit


This is the same Beehive shaped spring as the Beehive Racing spring kit. This kit simply uses a thicker spring base to increase the spring rate. Better suited for higher boosted applications of the 16v heads.

This "Beehive Racing Plus" spring has the following specs:

90# Seat Pressure at Installed Height of 1.450".
TBA# Nose Pressure at .400" Lift.
TBA# Nose Pressure at .500" Lift.
TBA# Nose Pressure at .550" Lift.
Coil Binds at .560" Lift so max .510 lift cam recommended.
