Thanks

I haven’t gapped these plugs for turbo so I’m not sure what I am running. I’m 99% sure that’s it and the springs just are not helping anything.

Could be. I've never had trouble with the plugs either. But who knows. And surely your springs aren't doing it any favors.

I've had spark plugs that blew out the spark when going into boost ,,, just like someone turned the key off
had my plug gapped to big (MSD system)

I think you mentioned getting flanges made up for the 9b (although I don't know why because they should be the same as the turbo you already have on there) but I say these on ebay.

Thanks,

The 9b is a triangle shape though not the Subaru style. I have access to a CNC plasma cutter but I’m calling in favors to use it so it takes some time. I should have it done this next week.

Oh. I didn't realize they were different.

Need stone thoughts on where to start trouble shooting.

Car started and ran fine about half way to work.

Half way there ( stoplights mostly nothing over 50mph) car dropped to 17:1/18:1 AFR at cruise.
Under load no boost I was seeing 14:1 ish.

Definitely lost power and seemed off.

Quick look in the lot showed no vacuum leaks that I could find. Fuel pressure was steady at 40 ish.

All the plugs seemed to be hitting. Idle was good though vacuum was 16 lbs per in not 18 lbs per in.

I had a similar situation several years ago, one of the injector electrical plugs had come loose, maybe check them.
Good Luck

Thanks I will.

Got it, had a solder connection break. I have heard of it happening never thought twice about it.

Live and learn.

That's tough to find!

It was severed. Super strange.

I've heard arguments for and against soldering in a car. To be fair I broke a crimp connection on my crank sensor once. So who knows.

I have a mix of thoughts. I have soldered items for a helicopter. But also used connectors. I’ll keep an eye on things. Just glad I didn’t wrap everything and bury it.

I was watching a building a house type of show the other day and they were putting up more than a few LED lights in a outdoor recreation area that did not have a roof on it... just a frame of sorts (forget what they are called) but it is what they did connecting up the wiring that was unusual.

The two joins (pos. and neg.) were staggered/off set from each other but the interesting thing they did was to make the strands of each wire into kind of like a circular fan where the strands were about 90°from the wire. They then put/butted up the two ends together then (it looked like) they joined the wires by wrapping them in a tight circle rather than twisting the wires together. They then did a light solder job and added a heat shrink wire cover over the join. They then repeated the same job on the other wire, shrink covered it they slid another cover over the two work areas. Again, these were not what you would call "beefie" /heavy gauge strands of wire.

One of the problems with soldering is you turn the individual strands of the wires into a solid which, as I remember, electricity and stress don't like to deal with (they don't like to deal with solids). Soldering the wrapped together wire (I think solves some of this but I am not 100% sure as it has been way too many years since I was active in electricity like radios [in the mid-50's and there has been a lot of change since then]). Attaching a stranded wire to a open or closed connector is another story as that is a clamped join of the strands but I have heard of people doubling up on soldering even there. As long as the heat and amount of solder build up is kept to a minimum I guess is should be OK.

This is "just a for what it is worth post".
