Default Question about gas & AP in Arizona?

I'm in Chicago now and thinking about AP stage 1 - we have 93 octane so I should see a difference.

I will be moving to Arizona in a little over a year and am wondering if you have 93 in Tucson to make it still worth while for me to get the Accessport if I'm staying at stage 1? I've heard that people with shtty 91 don't see much imnprovement.

Big improvement even with 91, I'm at a high elevation (NM) and they only sell 90 and it still does fine. Go Stage2 ! Plus you could always buy octane boost by the case (to get it cheaper) and pour Ĺ to ĺ a bottle per tank in to boost it up a couple points, I donít know the exacts on thatÖ I did it for a while and didnít see a diff, I just keep it in 91 Stage 1.

Yeah, 91 octane and 100+ temp in Tucson now. Talk about power drain during the day.

Torco has gotten pretty expensive, but is still cost effective in a 5 gallon can. It works out to be 30 cents an ounce. 16 ounces added to 15.5 gallons of 91 octane, nets 94.5 octane. $4.80 extra bumps you to almost 95 octane You can get by with 91 octane by using a few ounces at a time as you top off the tank. I have 93 octane here and in the winter I bump it up to 95 octane and keep my 17.5 PSI on the stock turbo.

I made a spreadsheet to help calculate the relative octane of fuel plus torco. Has the ability to plug in the last tank's octane number and it is used in the caluclation. It is an Excel spreadsheet and small enough to fit on most Phones/PDAs that will run Excel workbooks with functions.

Enjoy,

Dave

*edit* 8 ounces added to a tank of 91 would net 92.77 octane for an added cost of $2.40 per tank.

Trust me... In a little over a year, the idea of stage 2 will become an obsession and you will not be able to resist. Lots of people say "I'll just get the AP and stay stage 1." It rarely happens.

But about stage 1... I ran it on my 02 WRX up in Utah (91 octane crappy gas there too). The gains are worth the price of the AP. And really you need to figure into the equation that you're going to be able to re-sell the AP if you decide to... They sell for about 525 shipped (used on the forums) and they usually sell the same day you offer them for sale... So if you bought one used on here you'd literally be able to enjoy the gains as long as you want and re-sell it with zero loss. That's one of many reasons I think the AP is such a great buy.

I ran Stage 2 with a Crucial Racing Uppipe and Downpipe using the stock 3rd cat and stock cat-back. Even with both main restrictions after the downpipe in place, the car made 36 more peak wheel horsepower and 40 more FPT at the wheels. I gained a ton of area under the curve in the low to midrange area.

Numbers are not to scale due to the overlay but this is the baseline vs the stage 2 "stealth" using the COBB Off the Shelf map. For the cost of an up/downpipe you can have some decent increases with a car that looks, sounds, and even smells stock.

See my above Torco post. I carry Torco in the car premeasured in 8 oz cans. Have 2-3 of these and keep them in your trunk in a safe case or strapped to the side. Every time you fill up pour one in, instant 93 octane.

I have found a 5 gallon can for as low as 150 bucks + shipping.

I moved out from Chicago a little over a year ago, and i can tell you that even if you do get it set up to and run the 93, that i would recommend getting it retweaked to run the 91 we have here, plus account for the elevation difference. My 02 ran like crap when I got here.

agreed ... I can't remember what stage 1 was like though... I had it a long time ago, got rid of the AP for my rims .. then got the bug and bought a DP/UP and AP again went straight to stage 2.

Yeah yeah yeah. You guys and your 2.5L bottom ends.

I have tried to wear out my 2.0L, 70K miles and the darn thing is still 150 PSI all the way around on the compression test. Once it does go, then its 2.5L bottom end with WRX top end and different cams.
