Boost = HP?

[NavyZ28]

Im just curious... How much horsepower does a pound of boost make?

[pmr253]

depends on your cubes

[emile turks]

also depends on your compression ratio is really the main thing. Give you my example on 8 pounds my 400 and a 177 weiand roots blower made 400RWHP(rear wheel) and 428FtLbs TQ- on 12 psi(14:1 compression for me)- it made 434RWHP and 478 Ft Lbs.
Thats 30RWHP and 50 ft Lbs by a 4 pound difference!!!! Superchargers are fun toys. I run 8.28:1 static compression(at idle/no boost)

typically on a stock lt-1 1 pound equalls 18-20 horsepower this is stock cid and stock heads
