Ok...so tax refund money is coming in and I want to put a smaller pulley on the cobalt. I have a few questions I hope you guys can answer for me since I've seen a lot of people post about their experience with such pulleys. I was thinking of running a 2.9" pulley and get one step colder plugs. I will have stock injectors and my only other mod is an Injen CAI. My question is will I have any problems/issues running this pulley with stock injectors? I don't want to get a wideband A/F or scan gauge just yet because I won't be tuning, but I don't want to be running too lean either. Also will I have issues with the belt slipping with a stock tensioner?

Secondly, I was looking at Intense-Racing and South Florida Pulley Headquarters for a 2.9" pulley/hub package. Both websites have the kit for about the same price. Anyone have any recommendations?

Any advice here would be much appreciated guys. I wanna order these parts soon so I can put them on this weekend. Thanks.

 

You will be fine with a 2.9 pulley, just dont go any lower, Also i would take a look at billetflow they make some great pulleys.

 

can you please give me a link to their website?

 

no offense but i see this all the time and its kinda frustrating.. in the time it took for you to say gimme a link, you could have typed billetflow into google and easily found there web site.. hell you could just try billetflow.com and wala there it is. no offense but it irks me

 

no, you're right. i googled it after i made that post and found the website.

 

I would go with billet flow. And why not just get GM stage 1 or two then go with a smaller pulley? You'll be safer that way.

 

no way I'm going through GM for that stuff. Way too expensive and I don't trust their stuff. Probably going with the Intense kit if I go that far.

 

anything below a 3.0" pulley, u will need a new belt tensioner. im not sure how much belt slip u will have with a 2.9" on the stock one, but u def. should get a new one
