What are you running for plugs and at what gap???
I have the NGK Race plugs item nuber #4091 from FM that came with my spark kit

Gaps were set to .030 but may have opened up since then. I installed the plugs with the FM Spark kit back in November 2015. 2 track days on them, some street miles and cold starts and longer than usual warmups with the colder climate. Had very light misses very rarely before the event, ran 100% AT the event, would misfire 5-10 times in 5th gear coming home under heavy load, a few more of these pulls and easy driving miles later that went down to 2-3 misses per 5th gear pull.

Obvious thing is look at the plugs, which I'll do tomorrow. As always, I rushed to panic first thinking my rings were blowing oil by and causing misses, but starting the car the next morning revealed no unusual sounds, smells, smokes, nothing.

My question would be where did you get the gapping info??  If that was FM's suggestion fine but if it wasn't then you might be gapped too tight and the spark isn't hot enough and is actually blowing out at times.  The idea of a better spark is to be able to run a bigger gap and get a hotter bigger spark.

Okay from the FM website instructions for the Big Spark Kit

Install the NGK spark plugs that come with this kit. Gap to ~.035

Maybe it was a .035, I forget the number but Ken and I followed the instructions very closely.

The thing for me is that is was not missing at the event when I was beating on the car up to 7500rpm and 140mph, but after. I was also shooting some wicked fireballs that day, so I am sure I had some extra fuel going through the system. My hope is that it just fouled up the plugs on track and that they started clearing themselves as I was driving home after. I guess the IDEA of this is not impossible?

Can't wait to get this top finished in black. Wet morning as you can see, so I didn't have a chance to open up the car and check for spark issues. Will try later today. If still missing, will take a log tomorrow and send it to my tuner. Will also probably see him on May 22nd so we'll definitely get to the bottom of it then. May have to postpone next Wednesday's event due to weather. Really crappy 10 days coming up here in Philadelphia

OK, so the misfire totally went away. We pulled the plugs anyway to check, timing lines looked good and even, plugs not wet. 3 of the plugs were gapped to .035 as instructed, but one was at about .015 (cylinder 3). I can only assume that it must have hit on the head when I dropped it down the tube back in November, though I'm surprised the car ran so well with it that way. The only other way for the gap to close would be an impact inside the cylinder and I'd have heard or felt that happen if something was really flying through my chamber.



Rubber water return line is shot again, so I called Fab9 and he put together a nice kit for me with all AN-4 lines and fittings as well as heat sleeving for it all as well. Really didn't want to pop a hose on track or on the road for that matter, because its a PITA to fix and would piss coolant all over the place. Changed out oil and sent to Blackstone for anoter analysis, but the drain plug looked fairly clean.



Lastly, my mechanic made a bracket from the trans to the downpipe to keep it in place. It would either rattle on the subframe or rub on the steering column so this keeps it nice and centered. It's not easy fitting a 3" downpipe through there.



Also a friend of a friend is making me a nice SS heatshield for the turbo as we speak. Next track event is Wednesday this coming week but looks like it will get rained out anyway. I wouldn't mind running a wet day if I wasn't on slicks haha

Don't drop the plug into the hole.  Use a plug socket that holds it and slip it into the hole so there is no contact.

And the funny thing is I've been told that about a dozen times. I guess I only learn when I make mistakes on my own

Got this new heat shield from a friend of a friend, seems to be really sturdy but I will see how it performs on Wednesday. The biggest thing I wanted out of this box was to keep heat away from the brake components



Little barrier between the downpipe and brake lines (which are sleeved also)



Clearance to turbo

Got the hardtop plastic-dipped in black. Needs a few more coats of gloss but not bad at all for $40 As spotty as it is right now I'd still rather have that than the blue



Misfire came back, not sure if it has anything to do with something getting wet under the hood from the louvres but I'm going to throw in a fresh set of spark plugs today and go to my mechanic to get a log and send it to my tuner.

Showed up on track yesterday ready to go, come out of the driver's meeting to a heavy rain that lasted the whole event. I decided to exit the event and get my money put towards something else. Heard a few people spun out and one guy in a really clean 300zx spun at the final turn, wrecking both his front and rear ends when he bounced off a wall repeatedly.



Next event July 23rd, hopefully will figure out the misfire by then.

While I often advocate running in the rain, I can't blame you there. That car is more than happy to break loose in normal conditions, much less downpour. We may be seeing rain at NJMP this weekend also.

Alex is going to watch LeMons tomorrow night, I'm probably gonna be with the misses, but might try to come up there Sunday. Lap times were nuts, Alex usually runs mid 1:30s on Thunderbolt, yesterday bested a 2:19.

Got my Blackstone back, looking good for now

Had my last event of the season yesterday and besides a mystery flashing CEL (which I can't check via OBD because of megasquirt) everything went well and I hit my 1:35 goal around NJMP Thunderbolt. Head shield helped keep the brakes working better, but I think I metled the sleeve around my throttle cable because it feels really sticky after sitting for a few minutes. The cable also feels super soft and bendy behind the downpipe right where it enters the firewall, not tight like the rest of the cable. It was my second time ever on this track, and the last time I was on any track was 5 months ago, so I wanted to take it easy and not have any accidents last day of the year

Got more heat into the tires than last time, they perform amazingly and I still have time to shave since I'm braking for zones that don't require it.
