i found a brand new BBK set for around $100, the guy bought them for his cobra and never installed them. what exactly do they help out, besides being shiny and pretty? is this a pretty good deal? heres the link http://oklahomacity.craigslist.org/pts/1570553712.html

 

Don't waist your money

 

I can't speak for BBK udp's, but my Steeda's did net me a few hp. It was nothing i could feel, but when my bro and i used to race he was always a hair faster (consistantly 1 mph faster at the track) and afterwards we were dead even everytime.

There are better mods, but i'm happy with mine.

 

if you were to do underdrive pulleys, spend the extra cash and do them right and get steeda. efff the bbk's

 

I just spend $200 for UD pullies from STEEDA and I havent noticed any difference at all what so ever. Pullies were my very first mod on my stang.

 

I bought a set of Steeda UDPs from a fellow forum member and found a very noticable difference during hard (WOT) acceleration from 2500 RPM upward--which is of course about the only time there would be any difference.

As to the BBK UDPs the OP linked to--they are piggyback type, and worse yet made of aluminum, 100% junk--get the Steeda's...

 

Honestly there is going to be little to no gain. There really not worth it at all. The only reason i have them is cause the guy who built my motor threw them the cai and the 24# injectors in cause he took an extra day to finish lol. I didnt even care that he took the extra day. I dont care what anyone says your no going to feel a difference sorry...

 

I think they r some differences u may want 2 look into. All the one's I've looked at r 99-mid 01 and late 01-04. Ford changed water pumps mid 01.

 

I bought bbks, got them and looked at them, then sold them. I was very unhappy with them. Bought the steedas and love em and maybe be hard to notice the gain but its there and K_Z is right on the different pumps etc. from diff years etc, just make sure you do the research to get the right ones.

 

You don't want the BBK's. As cliffy mentioned, those are the piggyback style. Good way to do more damage than good. If you're going to get them, get the Steeda's.
