I was wondering if it will be ok to run a 2.8" pully on an engine with a injen cold air with magnaflow catback 2.5 exhaust without doing anything else. If not what else should I do.

 

uh use a 3.0 pulley. your asking for trouble with the 2.8. There has been a discussion on it before I believe... I will try to find it.

 

I agree

 

I plan on getting the rest of the intense kit real soon and I got the 2.8" for free so would it hurt to run it with it for about 2 weeks or so if I don't get on it?

 

if you run hard it will have crazy knock. I would wait. It only takes a few hard runs to screw something up

 

what knock are you talking about what does it do?

 

Your car is a 2006; they already tend to run leaner than the 2005 for the last few RPM's. You're SERIOUSLY not playing safe if you throw a 2.8" pulley on it without any fuel upgrade.

The only way I see you can run the 2.8" pulley (without fuel upgrades or any kind of adjustements) is WITH a manual boost controller PROPERLY INSTALLED on the RIGHT hoses and set at roughly 14 PSI, to be sure the extra boost is bleeded, so the air fuel SHOULD not be higher than 13:1.

FYI (For your information), knock retard is occuring when the ignition timing isn't optimsed, if you do a search you will read what it is.

 

thanks for clarfying. sick today I was going to say something but I passed out

 

Do not put this pulley on without the right fuel upgrades. So basically either wait for the GM reflash to come out or use the rev it up kit or intense kit. But don't install the pulley.

Technically you could install it and if you don't boost over 14 you will be fine but I WOULD NOT DO IT!
