    Just bought my Jazz Blue Pearl Challenger Hellcat yesterday and can't find the displacement. Anyone know? If the 6.4 is 392CID, I'm thinking the 6.2 is around 376CID.

    6.2L converts to 378.35 CID. So your close, but I would just use 378 CID.

    What is the CID if you count the 2.4L supercharger?

    I'm curious what others say. I thought the supercharger is induction, not displacement.

    I don't know. As a novice, what does displacement include?

    Displacement is stroke and bore. In otherwords, size of pistons and stroke length of crankshaft.

    6.2*61=378.2xxx.

    Always a pretty solid figure. Without knowing bore and stroke, using 61 will get you there.

    Not how it works. You don't add the supercharger displacement. It's still 6.2/378, with or without the blower.

    Bore-4.09
    Stroke-3.58

    Bore x bore x stroke x .7854 x 8=376.27

    What if it's a B5 with drag radials? How much displacement?

    With only 3 significant figures (measured numbers) the result can only have 3 significant figures, or 376 cu.in.

    Remember: 4,09" could be anything from 4.085" to 4.094" and 3.58" could be anything from 3.575" and 3.584"

    Conversely, if we can agree that 376 cu.in. is correct, then the correct liters is actually 6.16 liters. Car manufacturers always round up for motor displacement claim. (conversion 1 liter = 61.0237 cu.in.)

    They easily could have measured 4 significant figures, though there would have probably been some variation from cylinder to cylinder and not be precisely round.
