Without fouling up lol!

What else you guys run?

I ran TR6 all year long. I did swap them out periodically, but damn your fouling them up? Sure its not your gap setting or other issues?
How much of a shot you running? On 150-175 I gapped at .032" and swapped out them out x3months, but I raced like every weekend too. Never had a foul problem on the street, actually ran smoother or at least that what my wallet told my head!

No not fouling the 6s... looking for somethign colder then 6s that wont foul. Id prefer a plug with a slightly less projected nose, and a thicker ground strap even in the TR6 heat range... and if that cant be found I guess Im looking for one heat range colder.

Figuring out all these plug manufactorers part numbering schemes... very much info in them damned numbers

on my old NX 150-shot(wet);i ran a BR7EF...2 ranges colder.worked good.gapped at .038....but sam@TNT recommended me a TR6 for my 100-150 shot.

There is another NGK Plug, cant remember the name / PN i think is 2177-8 or something, it is one step colder, and handles over 175shot nicely
Anyway, I will see if I can get the number for you.

Oh I love the "search forum" button.....

Anyway, gosh was I off on that part number too, its R5724-8, same number plug Brent from TEA recommended to me when I was over 175, and a few others as well. It runs fine on the street, and does very well with juice, even as low as cherry 150shots.

Good luck...

Would there really be a problem with a TR-6 gapped at .60 on a 100 shot with no detonation at all?

'02SS

iTrader: (1)

woah .060!?!that seems a little wide.i usually hear .030-.040.but thats just me.

Exactly I always thought .35 was the norm and was suprised when my buddy who does mostly LS1's and race cars said he would gap at .60!

AC Delco R42LTS...........approx. 2 steps colder than stock ran them all summer and they still look brand new

sprayed 150 shot, but had them in because i was planning a 200, just never got the chance for the 200 shot

I am planning on going with a colder plug as well, but I have not decided what yet. I currently run a TR6 plug and I have sprayed a 175 shot and I checked the plugs immediately afterwards and they look good. I am pulling them out next week for some new plugs and my 3rd oil change. I change my oil whenever I get the chance. I do not wait for the 3000 mile mark. Royal Purple loves me..

I run the t6s gapped at .40 spraying 125 shot no problems yet

I don't think anyone has asked yet, but why are you looking for a colder plug?

CAT3

iTrader: (9)

Magic: I just looked at he needs a colder plug then the TR6 and the post by ATV ref: 250shot.

The 5724-8s are really nice plugs guys, not a problem at all on street, even in Hawaii's humid, hot weather in my daily driver.

As for plugs, if you have to gap that large, .060" you need to pick a different plug. Plug gaps shouldnt go over or under something like .010 from facotry setting, TR6 should be at .040", so between .030"-.050", anything less and it projects to much heat thru the plug, any more it losses energy. Can it be done, sure can, but its less reliable and means for more to go wrong. Just food for thought.

IMHO a .60 gap on a plug that cold while spraying is just asking for flame out. I think on a big shot you would be leaving a lot on the table with that much gap.

Here's the part numbers that I use.

BP7EFS----3526 7
R5724-8---7317 8
R5724-9---7891 9
R5724-10--7993 10

These are the ones that are liek the TR6's...They are tapered seat plugs. I prefer the plugs with the gasket to pull the plug even further away from the chamber to produce less hear. I cant remember those part numbers but I know Jeg's has them in their catalog. Ill look and post back.

I run around on 9's everyday, FWIW with no fouling issues.

There are some good points in this post as well...Id like to touch base on and give my .02 cents though.

When going to an even colder plug, to get some of the heat range back to not cause fouling, you will tighten the gap up even more. I ran my TR6's right out the box. I believe they were in between .035 and .040. Usually right at .038 when i checked them. Any tighter then that and it would be too hot for any good on the nitrous.

The 9's that I run in my car now are gapped at .028. I was told to go to .024 if I had any issues but I havent had any as of yet. Basically my point is, when you go to a few steps colder run the plug tighter to remain some heat for the combustion process so you dont get carbon buildup for the Daily Driven cars. Hope that helps.

Most likely the spark would be blown out. Any time you increase cylinder pressure with a power adder such as nitrous or turbos, or even blowers you need to run a few steps colder on the plug and a tighter gap so the cylinder pressure doesnt blow the spark out.
