Ok, i bought some Steeda Underdrive pulleys at the Fun FORD weekend in my hometown, just this past weekend. So today i decided i would install. Idid an oil change also. I sarted with the alternator pulley, its was bigger than stock. easy, then my water pump pulley was easy, bigger than stock. got to my crank pulley and had to remove my ele. fan so i could have enough clearance for my impact gun. Got the bolt out an used my puller and removed the pulley. My crank pulley is MUCH smaller. I buttoned it up and installed a new Serp belt. I took my drive home. And i still havent noticed anything. lol. Maybe it wasnt enough of a HP change for me to notice. I wanted to track it tonight, but i had to do laundry. So next week sounds good, and i will dyno also. I'll post the result. So they cost me 150 with the altr, water, and SFI harmonic balanced crank pulley. And took me 15 minuts tops.

I read a magazine article where they would install a part and then dyno after each part to see the increase and the steeda pullies only added 3rwhp

Thats three more than you had. I think in the Steeda ads they say it frees up to 15 HP. I dunno exact numbers.

My guess is 5-10 rwhp, probably not enough to feel a difference but it all adds up and like you said it was easy. Did you feel how light they were compared to stock? Thats gotta help too.

Im thinking 5-8 rwhp, I doubt anyone could feel it because its gonna be a hp increase across the whole rpm band - not just higher rpms like most mods

They all put out hilacious numbers...more like 3-5 rwhp.
