I just saw the group buy for the pulleys and wanted to get some input from you guys on what you think I should get first (CAI or the Pulleys...) Which will give me more power overall?

 

From the numbers I've seen you get more HP from a good CAI such as Injen's.

CAI (Nismo, Injen, Stillen + Z-tube) are all excellent bang for the buck, and east to install. Pulleys are also decent performance boosters, but are far more involved to get them in your car.

From what I've read, a CAI is best bang for buck and relatively easy to install. Lots of our members have the Injen, or Stillen, along with the Z-tube.
I've read that on our car the pulleys will yield about 5 or 6 hp and are more difficult to install.

IMO, it is still highly quesionable whther cai gives you any hp. Stillen for sure does not (lose 8-10 hp) per Doug from Crawford Z service. Not sure.

Pulleys DEFINTIELY give you power - but I, as many others, definitely would NOT insttall them on my car (they are single piece non-harmonically-balanced pulleys).

I would go with a Z-tube, as someone said aftermarket intakes seem to be questionable (one seems to lose power), and someone with a G35 has shown a 5.7whp increase by adding the Z tube. 5.7whp = 7 crank hp. $10 per hp, that's a steal. Also funny how it aligns with the 287 vs. 280 published difference between Z and G35 coupe!
