Need some help reading my plugs

[4*G*6*3]

I have looked at several sites on how to read spark plugs. but it wasnt really helping,they just ad extreme cases of this and that..
Sorry that the picks arent that great, i took them with my pc.

Here's the "mods" list.

*fmic. 2.5" piping/tb elbow
*bs delete
*bc 272's, bc springs & retainers
*arp head studs

thats pretty much it.


I'm running 12blbs of boost. the plugs i'm using are bpr7es.
I'm also running the stock 1g maf, bov is recirculated.

not sure if any of that info is needed but yeah:Misc.block:..

cyl # 1 & 3 have a white strip across the tip of the ground terminal that goesabout 1mm down, from there it's a grayish color down to the threads with a little bit of white towards where the ground terminal meets the threaded part.

on plugs #2 & #4 the ground terminal is gray, no white on the terminal.

on all the plugs, the electrode is white for the most part.

The bitch runs HOT btw! It never gets to the red or even close, but it runs hot. I dont like it..

looks like your running a bit on the leaner side of things but normal enough otherwise.

im assuming everything else is stock other than the listed mods?

the higher boost on the stock turbo tends to heat things up a lot, and if your running an automatic with the smaller stock turbo its only going to add to the heat problem.

white is leaner, black is richer, and you want a light brown ish color on the spark plugs.

can you identify if its running too lean by looking at the plugs? as in unsafe a/f ratios? I agree its running lean. would it fuel cut if it was starved enough? or something like that. theres no sign of det. on any plugs.

so brown-ish color is good. on which part of the plug? on the electrode or ground terminal or both?

Its a 5spd, with the stock 1g turbo.
The previous owner claimed it has a rebuilt block, with .40 over pistons.
thats all he stated. he didnt even know what cams it had.. so as far as internals go i have no idea whats done to it. all mods i listed are the things i have seen so far. the only thing i didnt put on the list was the morosso oil pan, oil feed relocation & aftermarket oil return.



thanks!

No, reading plugs is not nearly accurate enough. I also hope it isn't really .040 over...

[viridionplague]

No, reading the plugs is not accurate. just a general guideline for a rough estimate.

i usually look at the ground electrode.

these cars do not fuel cut if you are over-running the injectors. they stock fuel system hits it limits around 15 psi.

okay, thats good to know. why do you hope it wouldnt be .40 over?
