can i run the dub 2.9 pully safe? i did a search but nothing came up that would awnser that....im getting stage 2 and selling that pully that comes with it because i heard that stage 2 has a little bigger injectors than stage 1 and a diffrent power map than stage 1....dont know if it is true yet but if it is then i will get stage 2 if not ill just get stage 1 with the 2.9 pully should be nice with intake..exaust ....header...so if anyone here is runing the 2.9 pulley already your input would be great....

 

Yours is a 2005 or 2006 SS ?

 

I would use some kind of tuning/larger injectors with a 2.9 pulley. A lot of people are going to buy the stage 1 and the larger injectors and put 2.8" pulleys on. I might be joining in with that crowd, but I might also stay with the stage 2 that has the 3" pulley.

 

mine is 06 ss....im going to go very extreme with this car...what ever they make i will buy...ive had so many fi cars its stupied...i have just hit 1000k miles and already have the carbon fiber trunk...hood....cai....custom exhaust...and i waiting to see what you guys say about the pulley before i order it...but im ordering alot of stuff this week...pulley ...tranny mount ....adjustable belt pulley....wideband a/f gauge....tog header as soon as they sell to us..i missed the group buy. also i think im going to get my blower ported and polished and see what kind of gain i get from that and the pulley ....dont know yet...

i did not even realize i wasent hitting e ...my bad....im going way more than just stage 2...turbo.. twin charge ..whatever...hell im 28 and have a little extra cash to spend so why not.

 

first and foremost, its pullEy

and the stage two upgrade only comes with the pulley (at least thats what we've all heard so far)

i would wait for the kits to come out and then get a 2.8...

 

06 ss tends to be a bit leaner for the few last RPM's. First of all, you MUST do a dyno run along with a wideband meter to verify how exactly is your air fuel ratio at high RPM's with the stock pulley. Then you will see how small you will be able to go without blowing your engine.

 

this is why im waiting on the stage one before i do a smaller pulley...
