Does anyone have an under drive pulley? And if so where did u get it and if u don't mind how much did u pay and did u notice a difference?

You check with SLP?

I did see them. But I was trying to see if anyone had input on a cheaper one. SLP's is like $200, just don't kno if it will be worth that or not.........

if you get one make sure its the set for the balancer and the alternator, or else you'll be killing it in no time! check out speedengineering.com i think they have some

that site shows only little ricer stuff.

go to texas-speed.com they sell a kit that includes new belts and crank bolt for $250. if you think about it it is a pretty cheap power adder. say you have someone install it for you for $350, that is $600 total for 9 extra hp = $67 per hp. if you install it yourself its only $28 per hp!

the SLP version does not come with the crank bolt or belts, and there quality of products has been deminishing... i heard on another forum of a guy that bought SLP springs, and the box he got said Eibach, and they overlaid a SLP sticker on top of it, then charged him $100 more than what the Eibach springs costs.

The private labeling thing is a bit confusing but is done all over.

Eibach makes the springs and sway bars for every Shelby GT and in all of the Ford Racing suspension packages but the sway bars and springs are made to different specifications than Eibach's off the shelf units for the same vehicle. I know in Ford Racing's case every new part prototype has to go through the OEM durability tests before the parts are ordered. Sometimes they fail the tests. We have a lot of Ford Racing suspension packs for the 1994-2004 Mustang GT on backorder for months because Eibach's first sway bar prototype failed the tests.

I am not sure if SLP has the kit made to their specs.

no bro you went to the wrong speed engineering go to this one, if this one is ricer stuff then idk what your looking at??..... http://www.speed-eng.com/store/
