What should the compression ratio be for a turbo car?
Many factory turbo cars have a compression ratio of between 8.5:1 and 9:1, but 8:1 is a safer ratio for 20+ psi boost applications. Strong pistons won’t do you much good if those high pressures blow out the seal between your cylinder head and block.
Where do I Find my boost compression ratio?
Formulas have been developed that convert your static compression and supercharger boost to the effective compression ratio. Table 1 provides this information. You can find your static compression ratio on the left side of the chart.
How much horsepower does a Honda Odyssey have?
* With premium unleaded fuel (205 hp/217 lb.-ft. with regular unleaded fuel). ** Requires surge-type or electric trailer brakes, load-distribution hitch and transmission oil cooler.
What should the compression ratio be on a 92 octane engine?
Experience has shown that if you attempt to run more than about a 12:1 effective compression ratio on a street engine with 92 octane pump gas, you will have detonation problems.
What’s the compression ratio of a turbo car?
Turbo cars use the turbo to make up the difference. At full boost on a stock vehicle, the total effective compression can range from 14:1 to 17:1 with race fuel.
How can I lower the compression ratio of my engine?
By combining this method with low compression pistons one can start to think about running very high boost pressures when adding a turbo. The crank will also have some impact on the throw of the engine and the crank, piston crowns and rods should ideally all be matched up.
