Yeah i was going to say the same, a bit on the rich side, orange is definalty from the octane booster. Number 1 and 6 are a bit ritchen then most, well possibly it's the pics. Timming is close, but i was under the impresion that the top of electrode burn had to be as close to the end of the. quote

"Ideally, you want this blue line to be just below where the ground strap makes the sharp bend and above the weld. If you advance the ignition too far the blue will disappear off the strap and the strap will pick up rainbow colors (blues and greens)."

Anyway looks good either way

Hey,

first, I don't read plugs for mixture on the car because I have a wideband to do that

and the method I use on the bike is not a Good Thing for a turbo car :mrt:

Second, I'm no plug-reading expert but I have done it a few times on my bike

with expert help. On the bike, I have to run at the load and RPM I want to check,

then hit the kill switch, coast to a stop and pull a plug. If I idle to a stop I can't read

the plug because they're basically black like yours.

Did you chop the ignition during/straight after a full-load run then pull the plugs?

Because that line of what looks like fuel right near the electrode looks to me like

the car was idled for at least 20 seconds before the plugs were pulled. You might

need to try it again...

Hope this helps :)

Regards,

Saliya

Looks like your have a cracked insulator - so you may have a detonation issue however its hard to tell if there is any aluminium spheodites on the plugs as there is so much octane addtives. Not sure how poeple are saying that its rich as once the insulator and plug is that lead fouled the insulator doesn't get enough heat into it to burn off the deposits so the plug never cleans itself.

Typically pink orangy coloured plugs indicate coolant burning.

that is definately octane booster not coolant. its too hard to read plugs without knowing the condition it was running before switch off. from a quick glance i would think about 7's. Other than that a wide band is a far safer quicker tool.

Its definitely menstruating, wait a week or so and try again!

One question---------did you do a plug chop? or was this after you drove home and parked it in the driveway/shed?

Hi what are the brand of mags you are running on your vehicle?

I just drove it normally so yeah it probably idled a bit before it was turned off. I didn't realise the condition was dependent on how it was driven just before stopping it.

Yes I have used octane booster a few times.

I have also had some detonation. Lucky my forged pistons seem to be holding up ok.

You read the plugs for the rev range you want to assess burn for.

ie You drive at 4000rpm and do a chop, then you do 6000 and do a chop etc etc and its best done under normal load etc no revving in the driveway, either a dyno or a racetrack etc.

Or if your only interested in one bandwidth then do a chop on it only.

Sorry Saliya, just saw your reply, and you are correct.

      WA PITS: Am I screwed?

      I'm not up to date on the latest, but for basic modifications like pod filter, lower springs etc you can get a modification permit at the time of inspection.  For more serious modifications you will need engineering.  Intercoolers used to fall into the mod permit rule but its been a long while since i looked it up.   Either way you will be able to get it registered, just a case of $300 vs $3k .

      WA PITS: Am I screwed?

      Hi everyone! I’m the new owner of a 1996 R33 GTS-T, I’ve purchased this car over from Queensland and brought it to Western Australia and I’ve found that there is a hole cut out in the engine bay for the FMIC that enters into the wheel well (fender liners are in the boot). For anyone that has had to get their car over the PITS here, will this be a major issue?

      100% accurate!  We are a pack of know it alls....  But, I bet people go to you when they have a problem! I've been on a bit of a clean up rampage too over the past month!  I've thrown more shit in the bin over the past 2 weeks than I have in the past 3 years combined! Anyway, it's all good fun being different! My wife sometimes does not agree!

      ADHD in all form isn't about "can focus, or can't focus" or is hyper active or isn't etc.   It's all a dysregulation. Either time feels to be stationary, or time just vanishes in a split second. We are either under focussed on the task at hand (as we're over focussed on our surroundings) or we have no idea an atomic bomb went off beside us as we're so hyper focussed and locked in on things.   Not to mention the rapid fire thought process. What it takes a "normal" process to think up a solution to a problem, ADHD will be able to give you 5 different ways to solve the problem, and the pros and cons of each. While we can be highly impulsive and lack the ability to "control ourselves" we can also become paralysed with the inability to make a decision for ourselves. While most of us have an OCD like requirement for perfection, we lack the ability often to remain focussed to get things to a perfect state. Those with undiagnosed ADHD as adults, can often find the last part actually stops them ever attempting to do things that they have the ability to do, as the reasoning is often "if I can't do it perfectly, it's not worth doing"   As for projects... Ha ha ha, I still need to take the other half of my wall trim down in the Fiance's office so I can paint it. Need to finish digging and running the back yard drains, my R33, getting the Ninja bike registered (now being sold), the moped project, fixing either of the lawn mowers so they're reliable, along with a myriad of other things.   It's why I've been going through lately and just being brutal and clearing projects off that I won't actually ever complete. IE, moped will go to the tip, or be given away, bike is being sold, Subaru project being sold, some parts for other projects given away. Or I've been making myself focus on one thing at a time, by ticking off the smallest quickest ones first.   There's also a reason by our mid twenties we seem to be "know it alls", as we've all been down some of the weirdest and oddest rabbit holes when you follow the dopamine trail. It's often also why we're more a jack of all trades, but not a master of one.   However, pretty much all of my hobby projects, in one way or another, all come back around to automotive. That's my zen area.
