ive been reading alot of threads about pulleys and i thought maybe it would help me make my decision but it didnt ive noticed alot of people have went with the upper and alot with the lower what should i do? im thinking about getting the 2.77" Upper Pulley Kit from razor's edge for 129$ and from what ive read ill probably need to get the idler pulley so i dont get slippage right?

the only lower kits i can find are all rather pricy, but i would get the same amount of boost from doing either right?

also is a 2lb pulley ok to run with a stock tune? i wont be able to get the chip or programmer for while.

thanks,

chris

 

Lower pulley !

 

Yes a two pound is safe,, the EEC/ECU is set up to learn or re-teach it's self so to speak. Just drive out of boost for a couple hundred miles, normal traffic and you should be fine.

 

replacing the heavier stock lower may offer benifits too.

 

Why yes it will,,less rotating mass

 

The only reason to run a smaller upper pulley is when you are out of lower pulley options.

Smaller pulley = more belt slip
More belt slip = less boost, more belt wear and dust

 

thanks guys like i said i wasnt sure but now i think thats the way i am going to go anyone have a good place to order a lower pulley from thats not to $$$?

 

Try Lightning Force Performance. Good pricing!

agreed... get the interchangable lower pulley.. that way upgrading in the future is easier.

 

Much better service here..
