What a Tried and true 600 upgrades

Im sure someone knows how to get a tried and true 600 horse, or more out of the 3.5 motor.

What parts does it take to get there?

Thanks in advance

@Quasta is accurate. My Velociraptor is supposed to be true 600 with one exception as follows:

• AFE air induction system
• Air to air front mounted intercooler upgrade
• Intercooler piping upgrade
• Borla dual exhaust system (catback)
• Engine management computer software upgrade

It does not have any turbo wastegate modifications.

Not sure that I would consider anything Hennessey does as "tried and true", but here are the specs from their alleged 600 horsepower truck...

At one time I think they may have offered this truck with upgraded turbos but I don't think the bottom end can handle that much power.

You'd def need to replace the turbos. They won't push much more than 21-23 psi, they just aren't big enough.
