Im new to the club, abd to the cobalt, i resently found out that my newly bought used Balt has a 77.9mm pully and plugs, wut a find, im happy, but my question is, can the coblat ss/sc with a stage 2 run any fuel higher that unleaded? and if so wut and how

 

higher than unleaded?? dude if u have the smaller pulley and bigger fuel injectors u better be putting in that car premium or your car will act up... no other type of gas besides 91-93 or even the rare 95 should be put in your car

 

what he said

 

S2 is designed for 93 octane and we can only get 91 in arizona

 

that's OK, that's all I can get my hands on too. I've even managed to get a 14.7 at the track on 91 and that was my first time ever at the track with only stage 2 mod. It works, but not as good as 93

 

im the only one that runs the 81 economy huh ?

Damn I thought my SS/SC running 17's in the quarter at 87mph was damn good !

 

In Texas I was able to get 93 at the chevron all the time, since moving to Iowa almost everything is 91. Found one place with 92. my poor car was drinkin' 93 since I got it back in 05, these past few month have been hard on her.

Sorry lost track, To the OP check for blue bolts on your pulley and you may want to check your rev limit. see if goes to 7k. Higher than unleaded?? not sure what that would be. Higher Octane maybe, could you be talking about Ethanol??? Grain Alcohol burns good too but I wouldn't reccomend it.

 

we've got some stations with 94 in jersey. if you cant find good octane gas, why not add a small amount of octane boost every time you fill up?
