Pulled some fueling and put SEL scaling all the way to 100% - MBC limits to 1.2 bar mostly (though near redline it gets to 1.25). Ran about a 4.5 FATS right after waiting at a light - full tank of Shell 91, 45 ambient.

So after a few runs and tweaks, I call it a night and start heading home. Turn right (onto Page Mill from Foothill for you locals) and see two SS Camaros leave coming from the left, racing eachother. So I turned and took off after them. One of them puts his brakes on and drops back, so I pulled up next to him and gave him the 3 finger sign. Waited 5 seconds, honked three times, and took off at around 4500 rpm in 2nd. As you all know, 2nd gear is just brutally fast . The guy just sat there, and then when I passed his friend, he sat there too. Guess they didn't want to lose to an Audi . After leaving them I came up behind a Turbo, but needed to head home so I decided to leave him alone. I couldn't figure out why the Camaro guys didn't want to race - he was definitely looking over but then decided against it. I was driving in front of them for about a minute too, so they could have easily pulled up next to me again. Who knows...

Also, I'm getting a decent amount of misfires in Cylinder 1 at idle - all others stay at 0. If I give the engine a little rev, the misfires stop for a while. Any ideas? I probably get one every 2 seconds, on and off, so probably 20 in a minute. You can hear them when the car is idling, just little burbles.

Also, once Streetwerke gets their dyno I hope I can get to the bottom of the higher-than-normal knock in a controlled environment. I have timing pulled 2 degrees, and have the same file Brian has (Matrix/GIAC/Moss 91). I see around 17-21 mostly, but have one 24 and one 28 (in cylinder 2 near redline).

I won't pretend for a minute that I can understand the math behind it, but don't feel too bad about those times with your 275s. Have a log of your timing? We all love graphs

New spark plugs, right?

ATH

Yah new plugs - the timing is crap, drops down to around 6 with 100 throttle

PSmalls::DoggieStyle

Jeez

It seems others with less mods have been able to pull quite better FATS tims. 4.6s??? Thats stage 2+ time, not k04/k16, headers, i/cs, etc.

does tire size really make that much of a difference? looks like you should be near the top of em.

i see anywhere from 10.5 at lowest to 17.3 degrees of timing when WOT on my FATS runs. These were done at 17.5psi and 65*F ambient temps...hmmm maybe we could toooon our cars better i personally think i could see 3.5x FATS on 91 oct....without going over 18psi

ATH

There are several other Stage 3 cars running similar times on 91. Plus, and not to make excuses, but I have big wheels, big tires, and my car is a fatty .

Plus, you'll notice I said I was sitting at a light. Some people drive for a while before doing a FATS to cool the IC's - I don't really care, I'm just tweaking some stuff in Lemmi. But, I do have somewhat high knock, and I'm trying to get to the bottom of that.

ATH

But that's not the problem - the main problem is the knock activity. I'd like to figure out a way to find out if I truly am getting lots of knock, or the sensors are getting jumpy somehow. I have a vibration at 40 mph from something, probably a small bend in the wheel, so who knows.

ATH

My Stage 2 S4 only did .1 bar less boots than I do now.

Since you got new plugs, try swapping coilpacks (e.g swap cp of cyl 1 & 2) and see if the misfires move.

Just curious have you had it cleaned with seafoam, or equiv, yet ? As it's a 2000 I bet there's a lot of built-up crap in there.

What are you doing putting Shell in your car ? That stuff is cow **** ... STFA
