1000Hp Small Block Build Piston Comparison
|
This side-by-side comparison shows the difference between our original SRP dished piston (-15.0 dish) and the new flat-top JE piece (left), which actually has a -5.0 dish. With the engine's 9.4:1 compression ratio, the flat-surfaced pistons will promote better (spark plug) flame travel and combustion efficiency because turbulence created by the dish is eliminated. We reiterate that our move is being made simply because of the material used for the JE slugs (2618 alloy) is better suited to withstanding higher heat and pressure conditions brought about by our particular blower application. For those who wish to keep power in the 600-horse range, the less expensive SRP forgings are an excellent choice. View Related Article
