There is about to be a whole slew of 4-6 bangers putting pressure on our cars. Mercedes even has a 4 cylinder coming that's got 402hp with a electronic assisted turbo.

My new LT1 blower kit was $4,900 during the black friday holiday sale, currently piecing together the LT4 fuel system from ZL1 owners upgrading. Using an ethanol blend, I expect to be in the 650+ rwhp. My LT1 also weighs 3590, so the Z barely has a weight advantage (less than 100 lbs). These new Z's will not be making 600+ rwhp without turbo and fuel system upgrades. The infinity Q60, which shares the exact same drivetrain as the new Z, struggles to make 450 rwhp on a hot tune. Those 560 rwhp supercharged LT1 you speak of are all running 93 octane, low boost and no timing on a stock LT1 fuel system and that is why they perform the way the do.
