Lbs of boost with stock Roush pulley on 5.3?
I have read tons of threads and still can't tell what to expect from the stock pulley on the roush tvs on a bone stock 5.3. I have seen posts anywhere from 6lbs to 11lbs. I am installing one on my 12 Avalanche and was thinking about putting a 10% overdrive pulley on during the initial install so I can get it tuned once and be done with it. Which brings up the second question from what I have read the 10% overdrive will add 2 to 3lbs?
My educated guess is a Roush with a 6.0 would be 5 to 6lbs. A 5.3 somewhere near 7 to 8lbs and a 4.8 in the 9 to 10lb range. I guess this is why they had one pulley for all three setups.
What have you guys experienced?

9lbs is my target. Its crazy yours made 9.5 and smoke made 6lbs this is why I started the thread because I have seen so many different results. I would not have thought a ls9 cam would have made a 3lb+ difference.

This is my third supercharged LS vehicle so I have a little experience with mods and the effect of mods on a supercharged vehicle. I am trying to predict a base line of what to expect. If I put the tvs on and end up with 6lbs I probably wont be happy but on the flip side if I throw a 10% od balancer on and am at 12lbs or more I have probably pushed the envelope too far.
Thanks for all that have given your results and input.
