just curious what would happen. Is a TR6 really a "glow" plug with that kind of spray? I understand risk..... I am asking about cause & effect.....

I am aware a TR8 is safer.... but what happens with a TR6?

A broken ringland here. I added 4 degrees of timing instead of pulling said timing and well the pics show what 26* of timing can do with race gas and 10.5:1 a/f and tr6's. More info on this in the thread below for some insight, as we don't want this to happen to someone else.

is this statement considered fact by most?

robert, for what its worth, the plugs didnt do that. the plugs being a hotter plug will melt sooner yes, but at that point letting off the gas would prevent damage. a hotter plug with the right monitering and driver is accually good. you can feel the car nose over, and lift. if you can get a hot plug to last, a cold one is even better.

everyone says i need to run 8's on motor ect ect, i run 6's with no issues and over 30* of timming.

and if you where spraying a 300 shot would you still run the 6's?

Noyzee

i would not, but, people said i should run 11's, and i run 9's so i like to runner a hotter plug then most.

Well Dave misunderstood, I was running 22* of timing and meant to pull an additional 4*, but made a mistake in tune and added 4*. If you had read on it was stated. How in the hell Noyzee is running 30* is beyond me. it's not only a safety thing, but nitrous will in fact work better and more efficient with less timing. On my 408 and 300/350 I will see 16*/14* of timing.

Here's why my weak piston failed: pre-ignition led to detonation, which this quote explains very nicely:

So if ya want big cylinder pressures at the wrong time then run lots of timing on the spray.

Robert

Edit: My above pics and scenario is with Hypercraptic stock pistons, of course we can away with more when running forged nitrous pistons etc.

did you get my PM?

Uh, I have about 60 of them currently, so prob easier to get me here, but I will check later today.

This is my number 2 and 4 plugs...... the number 7 was the worst... bye bye ground strap!

you need colder plugs....those 3 cylinders got very hot...weird because the other looks fine, the 2 in the pic that have a ground strap...looks like they are right maybe a little lean but timing marks are right?

you blew that hoe up already...WAY TO GO...

wont know until a leakdown/compression test is performed. It does sound a bit fishy at idle now. Changing the plugs didnt cure the noise.

sounds like a bearing problem in the video, that may be secondary noise I hear tho. Sounded like Brandon's motor when it killed the cam and main bearings.

WizeAss

I doubt it.... either it is a valve issue.... or it is a ringland. The bearings should be okay. I checked all the rocker arms... they looked alright. It does have a loud pop on startup...... hopefully it is not the bottom end... but I doubt it wont be.

I have 8's in it now... a little too late huh? The standalone has plenty of gas in it.

ya never know man...have Billy or Daniel check it out. If it is hurt its the perfect time to try the big pills!

Mine when the ringland let go was belching aluminum out the tail pipe. you can see it in the vid in my link, I think, or another vid we had.

What timing were you running? I contend that maybe my tr6's would have been allright except for the timing turning them into blow torches.

I run 10s and still take them out on an occasion. It is all in the tune. You can run 6s but you better not have any timing at all. I run my motor on a total of 9 degrees while on the bottle. I also run very low bottle pressure 800psi to keep my tune in shape for the whole run and to not beat up on the temps in the combustion chamber. My EGTs are around 1300.

Mike what compression are your running. that plays a role in timing also. Where I could get away with 14/16 degrees with a 300shot and 11.25:1 compression, Guesswho could not with his 12.5:1 compression. So timing is relative to size shot and compression amongst other parameters.
