With SUPER COOLING, we have revised the flow of the coolant to reduce the variation in knock limit between cylinders.
Features
- The cooling water passages flowing into the front head have been enlarged, improving cooling of the entire head.
- A spare cooling water passage has been added to the direct injector seal. > Machine grooves in the head, as necessary.
- A cooling water passage has been added between the cylinders. > Drill vertically through holes in the block and head to match the position of the gasket holes.
Test Data
Stock GASKET vs HKS GROMMET GASKET
- With the stock gasket, knocking occurs in the No. 2 cylinder, which tends to trap heat, so even though the ignition timing is retarded by 1 degree compared to the other cylinders, the No. 2 cylinder has the highest knock level.
( SUPER COOLING Pro GASKET )
- Tests were conducted with the ignition timing set to the same for all three cylinders.
- There was almost no difference between the cylinders, and no knocking occurred randomly in any three cylinders.
Specifications:
- Engine: G16E-GTS
- Thickness (mm): 0.8 or 1.0
-
Compression Ratio: 10.6 or 10.4
Note: Head / Block modification required for cooling water passage
