Go to www.airbornemotorsports.com for the Tir pully kit "Eric" also sells a ultra-lite Tri kit. They may seem a lil bit hight in price but the craftmanship is flawless and they are all to OEM spec. just Alum. billet material (lite set) or extra machined Alum. billet (ultra-lite set)

 

for that price you can get the ones on rallitek.com for like 389 and they have dyno proven numbers(9.8 whp)

 

Where did you pick that up from tecniks, and how much?

 

Is there any risk of losing power for accessorys or anything else with pulleys?
