my setup is stock bottom end, milled patriot 5.3 heads, f11, bolt ons, etc etc etc.

Nitrous outlet single nozzle wet kit with 75 shot (actually has 100 hp fuel jet because it wouldnt drop below 13.0 a/f on the dyno with the 75 fuel jet). A/F on the dyno was 11.9 across the board

first picture is cylinder 5 and second picture is cylinder 4

do they look ok, im kinda new to nitrous





they are tr6's

 

was that after a wot pass?
looks like timming could be bumped up, it is hardley burning the strap.
looks a tad fat, and little low on timming. safe, but not as fast as it could be.

dont qoate me, i dont have my glasses on, but from those pics imo looks ok little on the safe side. (more then i would go)

 

black to rich
grayish/white to lean
golden

 

i only run about 25 degrees of timing up top, they car didnt like more than that NA. this was not after WOT runs. I did a bunch of wot runs yesterday but this was after a few miles of daily driving

 

Then reading plugs is pointless if it wasnt after a wot run. Make a wot run on the gas, kill it, then pull them and read. Send us pics then.

 

do the plugs have to be brand new when doing this? i have some TR6's with less than 1000 miles in the car that i would like to read after a nitrous run.

 

if you ran those plugs after a spray pass for any time on the street, put them back and do it over. the reading is no good

 

i will pull them after a wot run and repost pics

primary reason i was doing this was i was trying to hunt down a miss that turned out to have nothing to do with the newly installed nitrous system (broken valve spring)

 

You need to have pics so you can see down inside the porcelain. Looking at the tip don't tell you ****. Pull them after a wide open, and be sure to kill the car right after also. Don't let it set and run or you can get a false reading. Also, if they are brand new plugs, you aren't going to get a true reading until a few pulls/passes.
