6.0L LQ4 Whipple Supercharged

[tko]

Has anyone supercharged a 6.0L LQ4 with a whipple supercharger? If so, what kind of horsepower and torque did you get? I am considering a supercharger that is quiet and like the Whipple. Any results?

I had one in my rockcrawler and loved it . no dyno sheet or numbers of what it made .

We did a 427 RHS block and it managed 962 hp with only 18* of timing and over 800 lb ft @3,500 rpm. I wouldn't recommend pushing too much boost through these truck engines with stock internals, the rods and bolts used in the truck variants are not as good as the LS3 has.

What other brands of quiet superchargers are out there? What horsepower would be safe in your opinion on stock internals for 98% street use only? Thanks in advance!

What are your goals? You can safely run 7 psi on stock internals. Make sure to get a good tune.

I was hoping to make 650 horsepower. Is that possible on 7psi with stock internals? Thanks in advance.

It's tough to say. If you are chasing a number, it's easier to get higher dyno numbers through a Manuel. What are your plans?

Go to camaro5 and ls1tech. There is plenty of info in the forced induction section
