I still want more power but i dont know what else i can do, ive done almost everything lol and i dont wanna go with nos something else to get more power..
let me know tyf.com

Get a Supercharger camshaft, retune. Also, drop to a smaller pulley on the SC. Make more boost with it. Still tired of it? Then move everything over to a 6.0 or a 6.7L (408)

idk if u saw my signature but i already did all of that minus the the 6.0l/6.7l

I'd say a set of 4.56's.

i drive on the freeway everyday for work, would those be ok?

LS6 heads?

 

[KrautBurner]

LS6 heads?

there are much better heads out there than LS6 heads (especially for supercharged)


4.11:1 gears

don't be a *****,
give her a little spray

if you're considering going to a 6.0/6.7 etc
I'd say go with an "LSX forged block" and build from there.

How much boost are you seeing? What are your current dyno numbers?

 

[HMFDZ28]

Gears, Pulley, Forge the rotating assembly, build a larger cube motor.

Personally I would get a nice set of heads. Just be prepared to see the accual boost number drop due to the decrease in head restriction. So a nice set of heads, a pulley, and a retune.

7psi boost and im pushing 420hp and 392trq to the wheel

Pulley down, you have more power to tap.

i was thinking on doing that... but if i dont put new heads and just do a new pulley for more boost will i be save with the motor?

I was running 11psi on my 5.3L, you should be just fine, these motors are pretty stout. It is the drivetrain that is the issue on these vehicles.

will it be safe with 70k miles reason being is the place i took it to that installed everything said i have to change a few things to the motor so i can up the boost so idk

 

[JennaBear]

Hmmmm, I wonder what they are wanting you to change? Is your blower intercooled?

yup its intercooled

 

[JennaBear]

Ask them what they would want you to change

 

[renaldo99]

Ask them what they would want you to change

i am tomorrow but what i remember they were saying someting about the internals or something

 

[JennaBear]

I would definitely ask for specifics, I know plenty of people running high boost on stock engines.

they changed a few things when i did the camshaft like the pushrods and the springs so idk what else they can do
