Nopi Nationals Sept 24-25 Moroso

[SlowWhite]

went to Moroso last night: won't go back on a friday again felt like Rock Falls import day. other then track prep was good. I was there for 4hrs and only go 3 runs in.

1st run - 13.2@106mph on a 2.2- 60' (stutterbox launched at 6250 and almost stalled cause the car gripped to well) I raced against a GT2 Porsche that went 12.7@113mph He put 3 lenghts on me in 1st gear, a guy I was talking to got it on tape.

2nd Run - I went 12.99@108mph with a 1.98 (upped the launch to 7K) slipped the clutch in first and the clutch didn't hold so I had to shift into 2nd early again this was against the same GT2 but this time he went 12.1@114mph

after the 2nd run I was talking with a guy who owns a Firebird, and I was telling him about the issues I was having with my car, and that it seemed I got my high reving issue worked out, but I'm not sure about the spark issue. That's when I'd realized I'd left my spark plug socket in the car, so I pulled the #2 spark plug again to find it still completely black and full of fuel, I then pulled the #1 spark plug to find it a very nice grey color, I showed the guy the difference, and he couldn't believe I was running 12.9@108mph on what looks like either intermintent fire or only 3 cylinders.

I then switched the #2 wire with the #3 wire as shane wanted as I forgot.

3rd Run - I went 13.1@110mph with a 2.0 - 60' (I upped the boost a little)

After that the rain really started coming down so I called it quites. But not before weighing my car... 3100lbs with out me in it.

On the way home I had a lot of fun with the Mustang group:

2xfox body's were going at it on the highway on the way home, after the first one passed me I saw the 2nd one coming up from behind and when he got to about a lenght behind my rear bumper I canned it, and by the time he got to my door I was pulling away from him.

Now for the real fun part of the night - I came up on a Silver 03 cobra who was at the front of the mustang group, and when I cruised passed him slowly he sped up to match my speed, I shifted into 3rd gear at about 5000 rpms which is good for spool up.

When we went I got a little bit of a jump put about 1/2 car on him, then he caught up to my Front bumper before he had to shift, I then put 1 lenght on him, and then I had a car infront of me so I had to slow down.

He wanted another shot, he was practicing "Break Boosting" before he slowed down to line up against my car (ie: he was just sitting 2 legths in front of me doing this)

We lined up again this time I was I think around 4300rpms which isn't the best for immediate spoolup. but I got lucky he jumped the gun and then slowed up which allowed me to get higher into my RPM gear he matched me on the launch this time and we took off, He put about a nose infront of my car when he had to shift, then I put another 1.5 lengths on him by the time we hit trafic again.

The only reason I won these races were because I had a 9K rpms limit he was almost having to shift twice for every 1 of my gears.

Here is the log of both races:

I still have yet to pull the spark plugs to see if switching the #2 and #3 coil changed anything.

But I fixed the I/C pipe so it didn't blow off and I got my 9K Rev limit back.

So far there is no change in the spark plugs, maybe I just don't have enough time on them

It's not running good? Throw more boost at it!! That is awesome :D

[SlowWhite]

Well the car was starting out at 18psi and then climbing to 25 by red line like always, except at a much slower pass, I think when I did the boost leak test, I did something to slow it down. On the original boost setting I would have seen 56lbs/min but at the track I was only seeing 52-53lbs.min

Wasn't till I turned the boost back up to 22psi (climbing to 25 by redline) that I was seeing 54-55lbs/min again. Like normal.

The car honestly felt/feels like it's running great. if I didn't know about the #2 cylcinder I would honestly think there was nothing wrong with the car.

I just remembered that not only did I change the spark plug wires but I also swapped spark plugs, I swapped the #1 and #2 spark plugs before I left to go up to the track. And those were the ones I pulled and the #2 was pitch black like the pictures, and the #1 went from pitch black to a nice Grey.

Also I switched the wires so that #2 and #3 are reversed like shane said. But nothing changed (only about 19 miles on the car and about 5 pulls) So now what does that mean? could the CAS be bad? would the harness be bad? what are my next steps?

[Outlaw1]

Sounds like you have an injector problem or possibly an injector harness problem. Injector harnesses have constant voltage and are switched on the ground side. It doesn't take much of a chafe on the wire somewhere to get it to ground and stick wide open. Usually a problem like that is intermittent. When the car is idling can you feel/hear the #2 injector pulsing strong or does it thump like a dead injector? If you don't get that cylinder firing soon you might wash the rings out in that cylinder. Swap #2 injector with another cylinder and go from there. You have compression, your coil pack isn't bad, the amount of fuel is just overwhelming for the plug to burn. Hope you get it sorted out.

[SlowWhite]

I've swapped the #1 with the #2 injector - no change.

I've swapped the #1 spark plug wire with the #2 wire - no change

I've put in new spark plugs - no change

I've swapped the #1 spark Plug with the #2 - no change

I've hooked up the #2 spark plug wire into the #3 spot - No change

I've adjusted Timing so that it's set at 5 degrees - NO change

I have an oil leak that's pulling oil on my Valve cover, I just yesterday changed the Valve cover Gasket, along with all 4 of the spark plug gaskets and I'm still getting Oil on the Valve cover. Could this oil leak be part of the problem? I no longer get any smoke out the back of my car like I did when I went to Moroso for NOPI, not even when I'm Stutterbox launching.

At cruising speed my EGT's are at 14-14.5 (70mph), when I go WOT, at 9K Rpms my EGT's are sitting right about 1600-1650.

I have yet to change anything as far as fuel / Timing since swapping to 6 bolt.

But I did notice today when trying to adjust my HP configuration now that I know my weight. (3100lb car, with 225lb driver, Tires are 220/40/18) that the CAS invert isn't activated my car battery as died twice since I first posted when my fuel pump wire disconnected (I'd left the dome light on and didn't catch it as I never work on my car at night) So the ECU reset itself each time, I need invert the CAS right?

[Outlaw1]

I took it for granted the fouled plug in the picture was flat black (fuel fouled). Is it shiny black (oil fouled)? You should be able to smell the raw fuel on the plug if it's fuel fouled. Let's start at square one.

[SlowWhite]

I'll warm up the car again and then pull the plug. that way I know it's gone through a cycle again.

Do you have a tubelar exhaust manifold? If so how close is the manifold to your number two cylinder? I know that wrx's have issue with number two or three cylinder because of how the exhuast sits closer to that cylinder.

Looks like a T3 Turbonetics manifold with a Tial 38mm WG on #1.
