Nitrous spark plug info

[EmmerichLSx]

Maybe my plug should follow my tune instead of the other way around sense Nelson tunes it and I'm clear in salt lake. Or is that the total wrong way to be looking at things?

The reason people worry about the TR6 is because spraying makes the motor burn hotter. This increases the chance of burning up a plug tip, it breaking off, and ending up in your engine. Are TR6's right for nitrous? No. Do thousands run them? Yes.

I run them. I probably shouldn't, but I haven't changed them since I learned of this a few months ago. Next time I change I'll be going with the BR6.

I'm in no way/shape/form arguing with you. We've all seen the vids, you obviously know what you're doing. I know A LITTLE about reading plugs. Uncle has a 6 second drag car (was 2nd fastest on IL pinks) and he read them with his magnifying lense and said it was running little rich, but good enough for what I use the truck for. The timing marks were about right. My tune runs rich, so most likely where the problem is coming from. Plugs obviously weren't brand new before I made the run, but I did a 0-80ish street run on spray, let off spray, shut down truck, coasted, pulled 2 plugs, put them in a bag, brought them to him.

If tr6's were that bad, why would companies like NOS recommend them? Why would there be tons of LS guys running shots WAY larger then my 175 on tr6's/tr7's/tr8's, not breaking stuff constantly? It may be the sheep following the herd, but if 100 guys get in a boat to cross a river, and it works, I'm going to stick with them. The select few trying other stuff may be FASTER, but may also be spending more money experimenting.

The simple fact the NGK guy was "amazed by the fact" that people are using tr6's, makes me question his know-how. I work at a rinky-dink auto parts store, and 75% of the morons I work with, know that if someone asks for tr6s, they are probably running boost/nitrous, because all the rich kids come in asking for them in their loud ass gto/trans am/camaros. That is probably the ONE plug, that people know by "name".

Once again, not arguing, just trying to make a logical debate.

Why would you continue to run a projected tip? No one said the tr6 was a bad plug, just not the best for what we're doing. Anything you can do to keep away from detonation, the better off you are. I'm in no way trying sway you...I don't care what you do. I guarantee you you're uncle doesn't and wouldn't run a projected tip plug in his "6 second drag car". Like I said, this is just some info I've discovered and thought I'd share since there's not a lot of info on our truck sites about this subject.

So you run tr6's with a 175 shot? Awesome!! I'd be willing to bet you don't know how to read plugs...

Projected tip plugs have no business being used with Nitrous in any application. The non projected tip plugs are the same price if not cheaper. I think the last set of B8EFS I bought were less than 17.00 out the door at Oreillys. Anything with a 150 shot should be running a BR7EF plug. Unless you like playing with fire.

This is the first I've heard against the TR series. I don't have the bottle in the truck. The next set I get will probably be BR series, just to see how it acts. Like I said, I'm trying to get a logical debate. What's the downfall to BR plugs? I THINK the mustang guys use the same plugs as us, as do the camaros/firebirds. When I first stated I wanted to run nitrous, EVERYONE (on here, ls1 car forums, the NOS booklet, etc) told me TR6, TR7 with a bigger shot. If these were hands down better option, I would think more people would be running them/speaking up when others mentioned TR6. Projected has to have SOME benefit, non-projected has to have SOME downfall.

My truck runs like a total dog with the TR6 vs the TR5, I can only imagine running a 7 or 8 plug.

I daily drive on 8s and have no issues.. Did it with the 6.0 and with the 6.7. I didn't even think a TR7 existed.

[phantom405]

There is no such thing as a tr7. The projected tip 7 range is the bp7efs and the non projected is br7ef.

I don't believe for a minute that you can tell the difference in performance driving around between a 55 and a 6. No way.

Like I said, I don't care what you do. I was just passing along what I thought was decent information that you don't hear much about. After really looking into this subject, if you continue to run a projected tip plug with nitrous, knowing there is a better option for the same price, I believe you're a fool

ok this maybe a nob question but y does it matter if it has a projected ti. i mean what is the big risk of running it? Does it get to hot? do they burn off faster? what ? because i have heard of running the non projected tips but haven't really heard alot about them and are the br7ef's the plugs i should run because i just put a NX kit on my truck and im planing on spraying 250 to it

ok. you're right. I'm wrong. Done trying to DISCUSS. If there was no power difference, everyone would be running 8 range plugs on all cars because it's 'safer'. My fuel economy suffered, and I lost ability to spin tires from a dead stop (not that I could ever really smoke the 36's..but can atleast break them loose with tr5s). With 'nitrous tune' it got even worse, but that's to be expected from lack of timing. That was with a tr6 gapped at .035 vs ac-delco platinums with about 60k miles on them gapped at .050 or whatever original gap gm recommended.
