Underdrive Pullies?

C0BRAK1LL3R · April 6th, 2009, 08:17 PM

Really worth it? Make any noticeable difference? If so what brand?

moosenuk17 · April 6th, 2009, 08:20 PM

it all helps bro

BLK01SS · April 6th, 2009, 08:26 PM

I have ASP Underdrive's and I love them. It is a piggyback style crank pulley. I was able to notice an increase in bottom end torque and she seemed to pull a litte better up top. Just my .02

C0BRAK1LL3R · April 6th, 2009, 08:28 PM

Just wondering, trying to load up on some bolt ons, but dont wanna get what I dont need.

uspatricm · April 6th, 2009, 09:29 PM

ive been looking for underdrive pullies at summitracing.com and americanmuscle.com and just by reading the description they will free up 8-10 hp. which may or may not be noticable?

moosenuk17 · April 6th, 2009, 09:34 PM

wont open up 10hp, but will free up a few horses

uspatricm · April 6th, 2009, 09:41 PM

ok i just looked a little closer and steeda clames 8-10 horse gain, but bbk claims 10-15 horse gain and there high polished aluminum which is nice for 150.00 shipped, while steeda pullies are plain black billit steel and will run you 199.95 shipped. my opinion bbk looks like a winner. the asp pullies is that auto specialities company? if so there mighty steep! and there made of steel aluminum would be lighter right?

uspatricm · April 6th, 2009, 09:42 PM

yeah thats what i figured over rated so they can make a buck!

moosenuk17 · April 6th, 2009, 09:43 PM

well i got some steeda's for sale in about a month,

Scott2001GT · April 6th, 2009, 10:00 PM

ASP Underdrive's

damn thats alot

Willy Mo · April 6th, 2009, 10:39 PM

i got BBK underdrives, and they along with exhaust got me 251/287 on the dyno last sat.

04SN95 · April 6th, 2009, 10:44 PM

i've ran steeda on my mine and they freed like 5-8. ran great and noticed the diffrence on accel. ran like 200 shipped.

GTRACER88 · April 6th, 2009, 11:47 PM

UDP dont "add" hp, it just frees hp. I say every little thing counts. I have Steeda. Stay away from BBK because they are piggy back pullies. The bolts are known to break and can cause the engine to seize up. Steeda are the only company that i know that doesnt make piggy back pullies. They are worth it to me. No point in going cheap here. Here is how it feels. Turn your a/c on max then race the car... then turn it off and race again. Notice the difference? Its minimal but its there. Do it.

Willy Mo · April 6th, 2009, 11:52 PM

well from what has been said before. the 4.6 is internally balanced and theoretically doesnt need the external dampner. Its just used to dampen any extra vibration. but I got the bbk's and as long as you make sure the dampner is on there good and flush with no wobbleing and use lok tight you'll be alright.

Fluffy The Rhino · April 6th, 2009, 11:54 PM

The real gains are around 2 - 4 HP. Nothing more. Just like with the advertisements for K&N CAI's. $200 for a 2 or 4 HP "gain" is a blatant waste of money. You will feel zero SOTP gains from this mod.

Save your money for something else : D

Willy Mo · April 7th, 2009, 12:03 AM

^^^^ agreed unless you find some new for $40 like me lol

chefalan23 · April 7th, 2009, 12:48 AM

udp are such a waste, i forgot i had them on my car until just now. thanks for reminding me, ill have to add it to my garage

kjdionmemphis · April 7th, 2009, 02:44 AM

I am running a set of summit brand under drives on my 01 gt and i didnt feel a diff in it at all. i got the set with a sfi approved balancer. But every little bit will help

so in other words your looking at dropping a tenth on the e/t right?

schwarzGT · April 7th, 2009, 03:18 AM

Lol so we went from 8-10, to 5-8, down to 2-4 hp....which is it? 1-1/2 is my guess!
