projected vs non-projected plugs
projected plug=torch!
friend of mine just burnt up #5 hole.
he was on full race gas and thought he would be ok, but got nabbed.
ive ran them before i knew any better.
tr6=br6ef
"tr7" br7ef if you need one a lil cooler.
the ngk's are very easy to read as well.
great pics btw!!

Projected, non projected. A true nitrous plug will not have a projected tip, like the TR6 which always gets the KUDOS around here. Why? I do not know. the recessed tipped plug can dissipate the heat quicker, where as the extended tip can and often does turn into a blow torch affair, like 2nd picture. extended tip and detonation is not the sprayer's friend.

Verdad Gallardo The bottom set just needs to be cleaned up and good for another few hundred miles. Motor lost #7 only, and barely scored the wall, fixable. Combo of issues, one being the TR6...

The problems for the most part seem to be idle issues and of course not a very long life. I run it when going 200hp or less in my street/strip mode. Once I hit 200 and above then the 8 and 9 start coming into play. Others may have ideas and uses a little different than mine. Some guys run the TR6 at 200hp shots and seem to do fine. With that said, they likely do not know that the plug is probably turning into a glow plug.
Get yourself a good lighted magnafier and see what your motor likes, that is the best advice someone can give. You will be fine with either plug choice at your level as the cylinder pressure increase is not that great with a 100 shot compared to say a 200 shot.
Get yourself one of these (below) from the drug store (old people use em) and it can go along ways toward learning what works.
This is the type of thing to be concerned with. Signs of detonation IE: plug heat range, fuel octane, timing or a combo... the light can see even sooner the signs... little specks of aluminum transfered from the piston...
Hope this helps.

IIRC, those were with 285rwhp jets in quad nozzles and dry of course. I did win a big Dyno Shoot Out trophy that day... Not 100% sure they are one and same as we have many collections of plug pictures and sometimes forget to note what/when/why.

Honestly I don't know much about these as my notes were not very good. The brownish color is fine, IMO. We can see various colors from different fuels. Many can tell exactly what fuel you were running by the color it gives off. These did have some race gas on them, as well as pump gas, so actual color really tells us not a lot, except they are burning basically OK at the point they were pulled.

if you can keep the heat down, you might actually make a few more hp, not to mention the safety factor.
if you want to really get into tuning, you could try a 7 plug and see how the timing looks on it.
depends on the combo, but you might be able to get away with a degree or two of timing on the colder plug and go faster than with less timing and a hot plug. all while being easier on the motor.
He got off lucky with spraying only a 100-150 shot.
