2024 Chevy Silverado 2500HD ZR2 - Gas or Diesel for primarly hunting?

[Mike D Texas]

Based on your use case, gas will be your better option.

If you don’t work a diesel regularly, you will have issues with the emissions systems eventually.

As to payload, Ford and Chevy have increased their GVWR on their 2500 series trucks and they should offer plenty of payload, especially with a gas engine.

I would not do the supercharger. It will void your warranty and likely trash your transmission.

Curious, how much $ is the supercharger going to cost? That adds a lot of torque.

It's about 7-8k installed. It's a bit better than the 10k markup.

It doesn't affect warranty as it is easily removed and uses all stock engine parts.

As long as we keep the extra compression to 6 psi or less it's the same compression as the diesel turbocharger. No risk of damage or stressing the transmission or rest of the power train more than what the diesel would do. Remember the diesel is 975 ft-lbs torque. We're still less torque at 700 ft-lbs @ 6 psi with the procharger.

Also keep in mind that as we go up in altitude the air is more thin which is why the diesel does better - again mostly due to its turbo. At say 12,000 ft we're 66% as dense as sea level. So the procharger with this conservative setting gets us back to sea level pressures. Not bad at all - completely reasonable.

Many people jack it up to 8-12 psi, so we're 1/2 under max.

One downside is we now have to use higher octane fuel. Above 1,500 we need 91 octane. If we go down to sea level - 93. We're probably fine to stick with 87 at 7,000-10,000.

Given those octane levels also shows the setting is conservative engine wise.
