OK, I added dielectric grease to the plugs gapped at .040", added 2 10awg GND wires from the intake plenum (MS GND) to the block and to the chassis. It hiccupping at high load where the log stops all together (the end of the log). I tried several times and it keeps killing the log at the hiccup.

thoughts?

I used the same MSQ on both logs. #1 (go to time 570) and there was no hiccup. Log #3 has the hiccup at the end.

I can't run a gap any larger than .35 without getting blow out.

I've been running .5 and its been fine all along, even at 16psi. I guess I can take them down to .3 tomorrow and see what happens.

With COPS and MS I still never went over .041...

No wonder the DOW dropped 1000 points.

I vote for smaller gap too.

Too much gap. The misfire is killing the log. You'll need to run less gap or more coil.

In for your $268 worth of race coils...after all, size matters.

+ a few! Re-gap your plugs, if for any reason, just to find out what happens. It wont cost anything. I cannot run more than a .022 gap with COPs without blowout @ 18psi.

Screw that, I'll smash teh plugs back down today...I'm in the market for a Kayak ATM.

I'll put them at .3 then try .2 if I must. Those DIY coils are sexy-time but I don't care to spend any more money on the car, nor do I have the brain power for that.

You shouldn't have to go much below .035, but I know you are moving a lot more air than most of us.

What kind of kayak? Recently did a lot of research, ended up with a decent SOT, but highly recommend splurging on a Hobie after getting out on the water. Mine doesn't track well, and I ended up making my own custom dual bladed skeg to cover more ground with less corrections.

This is only 11psi at 250whp.

I'm looking for a POS on craigslist. I'm not dumping stupid money into a kayak.

So why would spark suddenly blow out when its been fine for over 1-year?

And why would a misfire kill the logs?

In that case the Pelicans are the best bang for the buck. I found a $400 one for $250 that had been used twice, and the guy threw in a decent paddle (worth paying for).

Good luck paddling, it's a lot of fun, and great exercise weakling.

I can't see the logs at work, but maybe take a look at your voltage. Charging system issues can cause this, and it may be an early symptom of a weak alternator.

I have extras if so, including one that was "rewound" and may put out a little more amperage. Yours for the usual favor...

I run the BKR7E gapped to .032 IIRC... whatever they come pre-gapped to, I just make sure they are all identical before installing. This is at 22-23 psi with a single MSD coil and a distributor, 8.2:1 compression. No blowout ftw. Upgrading to DSM turbo coils shortly, and hopefully opening up my gap a bit as a result.

Misfires of this nature will create all sorts of awful electrical noise, which can do weird things such as cause a datalog to terminate.

Ignition coils degrade over time. They are consumable like a belt or tires, and they'll wear faster the harder they're pushed. Big gaps through lots of boost is pretty hard on coils.

If it weren't for DIY and the braintrust here, I wouldn't have a car like this. I'm going to attempt to stay out of the bars tonight and close the gap.

Bring the plugs with and gap them at the bar. Problem solved!!!

Plugs are gapped at .022 and still hiccuping, here's the log:

This is at 123.953s? Can you post your msq?
