So a couple of nights ago I was with my friends at a parking lot when I saw another SS drive by (SS/SC G85 same as mine). Ive always wanted to race another SS so I call him over and asked if he wanted to go. He asked if mine was stock and I said yes. We both revved our engines and his was a lot lower pitched and quiter, while mine was a loud, high pitched whine. He didn't think mine was stock but I assured him it was ( a mechanic at the dealership where I got it from owned it before me, and the salesman told me it was stock). So were going 40 on the road and I honk it off and go. Wow, that wasn't even a race he was far behind me. So we go back to the parking lot and pop our hoods, he ballpark measures our pulleys using his hand and phone , just to see if mine was smaller and it was. I was suprised. I just had a couple of questions. Does that mean I have stage 2? And how do you measure the pulley? I still redline at 6500rpm. I also asked him how much boost he got, he said 10psi while I get 12.5psi. I have no CAI or any other performance mods. Any thoughts?

He must not have had a ss/sc then..

Stock S/C pulley makes 12.5 psi.

If he's at 10 psi he must have a ss/na that was supercharged or a 2.2...

Does your pulley have bolts in it or no?

AaronHoffy

No it was the same model as mine, recaros, wing, same badges and everything.

Under his hood looked exactly the same, 2.0 ecotec with the M62. And I don't know I'm at work right now, ill see when I get home.

He must be having some problems internally then. Car should be making 12.5 psi STOCK

Yes we did.

It was also a warm humid night, around 90degrees if that effects anything.

Thats a stock pulley so I don't see how his is bigger than that.

AaronHoffy

Damn, he must of just said that for an excuse.

my guess is his boost bypass valve is not fully closing and some boost is bleeding off. 12.5 psi is stock, and if you slaughtered him with a stock car, he has to have something wrong.

AaronHoffy

He said its throwing sensor codes too. Thanks guys for your help.

if its throwing codes he has problems and thats why its slow.

IC pump is probably not working on his car.

I was only getting 10 to 11 psi when I was stock.

Maybe he got confused and thought a bigger pulley would make his car faster.

Bigger is better.

Totally makes sense.
