We have adopted and renewed very popular "Independent bead shape" 4G63 yet for RB26DETT which is still very active in the tuning market.
Feature
For the race the "Independent bead" is the main stream of the water holes or Head Bolt holes. So even if the firing gas is leaked because of big power setting or degradation, it will reduce the risk of overheat by making it water holes independent bead.
By redesigning the water holes area between Head Bolt holes and bore, it will protect head from water flow in because it will prevent the crack at the Head Bolt holes block.
We also have redesigned the stopper and bead which make less likely to leak.
Bench test vehicle was 660ps and actual drive test vehicle was 600ps and 80kgm torque at a circuit.
It comes with conventional products of exhaust manifold, intake manifold and metal gasket of throttle.
Remarks
We recommend to use with strengthen head bolt kit.
For φ86 & φ87 piston (Independent Water holes)
The Performance requirement from Head Gasket.
As the cylinder block and head are not rigid body, when the Head Bolts are tightened, the gap between the surfaces and the surface pressure applied is not even across the whole surface. Moreover, due to combustion pressure and vibration while driving, the conditions are continually changing and the contact surface is being continually beaten. As a result, a good gasket must ensure that contact surface pressure is spread as evenly as possible and also adapt quickly to the ever changing gaps that can appear in the contact surface to maintain a good seal with good pressure.
STOPPER TYPE HEAD GASKET
A high pressure seal is formed around the combustion chamber through the use of stoppers which create a step within the gasket for optimum sealing. By making the stopper part of the plate also allows the fold to be smaller while maintaining structural integrity. One side of the plate is completely flat meaning that it can be layered with the stopper to allow stoppers to be used in even the tightest of locations around the combustion chamber forming a high quality seal. Compared with other gaskets of the same thickness, there are more layers in these gaskets giving flexibility which allows the gasket to maintain a good seal even when the engine tries to vibrate and move.
