Hey guys im new to the site. i have an 06 ss s/c. and i dont think i seen this question that i have. i was wondering how small of a pulley i can have on the s/c without changing the injectors/ harness. and to my knowledge the stock pulley is 3.34 rite? thanks and if this question has already been answered i'm sorry..

 

2.9+

though 3.0 is what the safe recomendation is ...

 

I would say 3.0, that way you dont need to replace the belt and tensioner pully...

 

ok so a 3.0. what kinda of difference should i see with that? i already orderd teh aem cai, it should be coming in this week.

 

you will notice 15lbs over stock 12.5, boost comes on instantly, and that intake is going to make youre little M62 cry loud as hell.

 

15-15.5 psi....... roughly 20-25 hp, 30-35 with intake and pully, you will like it........ trust me

 

don't you need to chang the plugs if you go with a smaller pully?

 

Yeah I would get a range colder plugs. South Florida Pulley Headquarters sells them.

 

yea thats what im looking for. i cant wait to hear the whine! i already have changed the spark plugs to the ngk iridiums. i read it on a previous post for the intake. so i dont throw the CEL. i have one on in my tiburon and it drives me nuts! thanks for all the info. i'm def. ordering that pulley next pay check!
