What's the compression?

 

Here's the listed Compression Ratio and additional specs...The static compression ratio depends on your head, headgasket, rod length, etc. Then your cams and whatnot affects your dynamic compression ratio.


This new strutted 1400HD forging has been developed for turbocharged methanol Mitsubishi 4g63 engines, making 350+ horsepower per cylinder. Got a large aftermarket turbo, tubular manifold, high compression, nitrous, and methanol injection? - no problem. The forging has been designed around special 21mm and 22mm tool steel pins of .225” wall thickness.

2618 Alloy: The strongest alloy available with the best strength at high temperature and low silicon content, for low porosity.

Heavy Radii: Creating a large smooth radii from the skirts and pin boss into the crown prevents flex and cracking.

Piston Specifications:
- Stroke: 3.465" (88mm)
- Rod Length: 5.905 (150mm)
- Compression Height: 1.378 (35mm)
- Head cc's: 47
- Dome Dish: -14
- Gasket Thickness: .042" (1.1mm)
- Deck Clearance: 0
- Block Height: 9.015: (229mm)
- Compression Ratio: 9.0:1
- Pin Diameter: .866" (22mm)
