Well stage 2 is on its way! My question is this:

Can I put a 2.9 pulley on the stage 2 tune up here in Calgary without problems?

I know everyone is saying that you can, but is it still feasible with our altitude (3,438.3 FT), anyone done it up here? If so can I get away with Mowhawk 93 oct?

 

I did that on my Ion Redline and never had a problem. Keep in mind, at this altitude, the air is thinner. You can get away with a smaller pulley at high altitude compared to sea level.

 

yeah. You should also have one of the guys in calgary with hp tuners tune your car after that. Shouldn't have a problem at all.

 

Running them in a lower elevation here and no problems yet.

 

go for it man, I did that when I had the stage II setup on my car and I didn't have any issues either.

 

thats what im running right now, been on for about 10000km's and no problems

 

yea im running it as well, on the stage 2 tune, it runs great.

 

not to thread jack but if I buy stage 2 used except the belt you think the dealership would still honor warranty?

 

id ask before trying... they say to keep warranty they need all the parts in the GM SEALED packaging, that way they know nothing was tampered with

 

if you get GM to install it they have to warranty a GM part.

 

sweet i'll give them a call tomorrow and see what they say. Thanks guys

 

awesome what are you guys using for fuel? how many are using stage 2 tune?

 

I'm using 94 but I don't have a stage II tune.

 

With that tune, at the track, I was using Husky 94 and a gallon of toluene!

 

where do you get 94 octane? I have only seen 93

 

There's a few Husky's around town that have 94 octane. One of them is the Husky on MacLeod by 42nd, another is near Bow Trail and 37 Street. The Mohawk on 16th by Edmonton Trail also has 94 at the pump.

I think there might be a few more, but those are the ones that I know of.

 

im pretty sure husky down in sundance has 94, or it could be 93 im not exactly sure. i usualyl run 91or 92 depending on what the gas station im at has

 

i have the same set up with no problems and im at sea level

 

Any ideas what numbers we should be getting with that setup?

 

my PSI was peakin at about 16, with the stage 2 pulley it was peaking at about 13 i think.

 

With my stage 2 I have seen 15psi.
