Well my first run was 14.956@92.50mph 60' 2.205 and then a very long (1hr 30min) wait for second run (someone spilled oil on the track) the whole time I had a bag of ice sitting on the intercooler then I ran the 14.662@92.88mph 60' 2.112. As far as tire inflation the first run I was in the middle of lowering the pressure when the line started moving in the staging lanes so i only got the rear tires done at 26psi. and the fronts were at about 40psi, that run I spun all four tires when I launched at about 5k. then second run I got the tire pressure right all the way around and got a nice launch at bit lower rpm about 4300rpm. My tire's are Bridgstone Potenza RE92A's size 215/45/17. I think on a good day I would probably do about a 14.4 all stock.

Not very far from my house they have a pump like that up at a Sunoco or something. I should see what it can do, lol. Its expensive as crap though. I think its like twice as much per gallon as 93.

Most likely the gas there is leaded which is bad for your cats and injectors.
I ran 110 leaded for over a week and never had probs with my injectors. I think that is a myth. The cat on the other hand... RIP.

It's not going to kill them right away, but in time they can get clogged

My turbo's fixed and a lot better =)

Nice, I always wanted to try 100 octane, but all they sell around here is 115...ohh well. I mix my gas like a 2 stroke 1 gallon 115 to 3 gallons 93

I know of a couple places that sell 100 octane, highest rating sold in california that won't harm the cats on street cars.

But like any other car unless your tune or mods ask for higher octane because of timing etc. then it's not going to do much good.

I got a PDX race gas map (and a new base map) for $200. I don't have a protuner within 300 miles of me, so that was the way to go. I'm mapped for 100 no lead, which I can get 35 miles of twisty canyon road from where I live @4.60 per gal. Life is good !! I'm going to try Torco race gas concentrate for next years track events, since fuel is quite expensive at the tracks I run. So far, after only one track day, I'm happy with their maps. I'll post after I try the Torco.
