I've heard around 500RWHP I believe. But as far as CFM or any other "air" ratings, I dunno.

Anywhere from 5200 to 5800 rpm (dependant on the weather) on a stock 6.0 liter with a Radix and a 2.9 pulley

Same goes for a 5.3 with the same pulley.

I bet I'm seeing as much or less boost than you though. I'm only pulling 8.5 with the 2.9 pulley.

looks like mine will go there too, I'm reading 52lbs/min at 5600rpm in 2nd gear, I imagine if I rev to 6400rpms I'd be right at 60lbs/min.

thoughts?

Technical explanation:

the MAF actually reads in Hz. The amount of air is defined in the MAF tables. A given frequency is defined as a number considered a measure of how much air is moving through the MAF.

I don't think you have anything to worry about right now. Are you cammed ?

no, and I'm not really worried, just curious.

I only pull 8 psi in the warmer weather. A few days when it was in the high 40's, low 50's I pulled 8.5 psi.

It's really not surprising as it's the same supercharger with the same size pulley. It should move the same amount of air. How much boost that equates to should be somewhat variable, though.
