? on Underdrive Pullies

[JR98]

Hi Since its almost tax time i wanted to know what u guys thing on underdrive pullies r they worth getting, they say they will give from 9 to 15 horsepower but they r like $200 with the SFI Cran pullies. Do u guys think i should get them?

Save your money for something else.

THEY DONT MAKE ENOUGH OF A DIFFRENCE AT ALL ON THE 4.6 THAT I KNOW OF. SAVE FOR A REAL POWER ADDER.

going to do nothing but burn your alternator out faster.. not even 1-2hp will show up on an dyno.

do get them man. if you do just go out side and set 200$ on fire cause that would have been more fun than a set of underdrives lol. i had some bbk's on mine when i first got her. and i had to get a altenator. so i toke that shit right off.

Not sure what you guys are doing wrong, but I had Steeda U/D pullies on my car for over 4 years (before I installed the Vortech) and they made a power difference (picked up over a tenth and a mph at the track on the non-PI motor) and I never had a problem with the alternator. Maybe the other companies pullies are inferior? I used Steeda, and was very happy with them. I transferred them over to my PI motor as well when I swapped it in, still no issues.

This is one mod I'm really confused about. I hear good and bad about them. And all the people who uses the Steeda pullies are happy. This is a mod I wanna do but it's scary to see the reaction from people.
