RE: 252 rwhp stock
id say 50 rwhp. that would equal depending on stock numbers 275 rwhp. figured about 30 from the whole exhaust. and id say about 20 25 from the underdrives the cai & mam. dont take that to heart.

10-15 from the exhaust set up. Maybe an extra 10-15hp from the rest. UD Pulley's on a 4.6 won't do a great deal. The 4.6s stock pulleys are more agressive.
I'd say 25+rwhp total.
Not really anywhere close to 50+.

RE: 252 rwhp stock
there has been quiet a few dynos showin 15rwhp from magnaflow x and catback. LT headers id say 15hp .so you are sayin the whole exhaust combo will give him 10 to 15. hes got the maf done with the cai that can put out at least 12. and i give the underdrives 5. if hes got all that for 25hp then i better get another car. lol. i dont know i think you are figuering alil low.

lt...............20 rwhp
x...............7 rwhp
cat............5 rwhp
cai............8 rwhp
maf...........7 rwhp
pulleys.......6 rwhp
adjuster......7 rwhp
total - 60 rwhp
So I'd say you have between 280 - 285 rwhp, thats assuming your still in good tune and a/f is right. Thats about 325 flywheel horsepower.

Underdrives on a 4.6 will add maybe 3rwhp. I've seen numerous dynos of them. Ford started getting more "Aggressive" with their pulley designs so unlike on the 5.0 a UD Pulley doesn't do as much.
I doubt he's gained 60 or 50rwhp. I'd say 40 to maybe 45.
