6lb's safe on a daily driver. I like to go on high speed runs and currently am running a safe tune (running 110 to 120 for a few minutes). Really debating. I know some of this has been discussed before.

 

ok...so i made a newb post. looking for reassurance

 

So are you contemplating a 6# pulley? Maybe I missed your question?

 

It's all in the tune, make sure that your driving habits are explained to your tuner, would I run 6 pounds on a vehicle that sees that speed for a long duration? No. I would find other ways to increase power without pumping up the boost. What do you have in your truck now?

 

I don't know whats in the motor. i know the previous owner pulled it and it has no dates on it...so. guess only place to go is time for a motor, and help out traction.i was going to get a reichard racing 2lb upper.

 

nate, make sure your tuner knows that you like topend runs, so he can tune it right. i would probably stick with your 4 for fear of what happend to terry with his 6lber and his top end run.
