Pettis Performance 598Ci Race Engine Ring Tension Test
|
One more test with the pistons is performed, Pettis checked the ring tension. He informed us that you want around 26-28 pounds of oil ring tension with a nitrous motor. A race-only naturally aspirated setup can go down to 8. But on a nitrous engine you want more so no oil passes into the combustion chamber, which can lead to unwanted detonation. You lose a little bit of power but the dry combustion chamber is worth the trade-off. View Related Article
