And a 4" intake should feed it fine, just be sure to scale the MAF for the tube size where the sensor is.

That 2.5 upper and 10% OD is going to put you into the 20 PSI range (if it doesn't slip) and your exhaust being restrictive will make that number go UP not down. I run a 10% OD lower and a 3.3 upper and am in the 10-11 PSI range. My cam is a 219/234 on a 118+6 from BTR and I made 518 RWHP.

I don't think he will be over 20lbs with his set up. I'd bet more around 15-16lbs. I had a 2.5" and stock crank pulley on mine and was a little over 13lbs. Stock manifolds, y pipe, cats and 2.75" exhaust/muffler. His will flow better than mine and his cam is slightly bigger and on a bit tighter lsa. Gonna loose some boost there too. Stock pulleys on mine made 8.5lbs and I'm running a 2.85" now and am right at 10lbs. If it were me I would start with the overdrive crank pulley and stock upper to see where you are at. Then pulley down if you wish and you have an idea on where you will be. These are just my opinions though, based on my lsa blower experience so far.
I am running 6.2 flex fuel injectors but don't know the duty cycle. I have to be getting close to maxing them out, but if I pulley down and run out, I'll probably swap to a id850 or id1000s.
