I had an OD 97T in my Argus for about two gallons including break-in, and as far as I can remember I only took it out because I felt like I should after that long. And have never had issues running them in anything else. Even their standard plugs - the purples - are the best for MT .28's IMO - regardless of the fact that they are cheap.

Thats awesome

try to lean on a 97t though ;)

anybody....Monty??

Heavy flywheel will smooth low speed torque of engine and will provide better traction by doing so on most fluffy/dusty/loose track conditions

lighter flywheel equals just the opposite and better for high traction situations or truggy

now back to your regularly scheduled novarossi talk , lol

I had a issue with nova plugs only lasting one 7 min heat
And arfter throwing 4 down the drain as being dead I did a last ditch effort
And put a p3 in there and no problems didn't alter the tune or any thing

Now last week I thought my x7 was faulty as I was killing plugs on run in
So now I'm thinking it was the plugs so in total I killed 8 plugs in one gallon
But as soon as I swapped both engines over to p3 no issue

I haven't had a issue up to this date with nova plugs

Plugs
 

The 97t is a pretty hot plug. I agree it's great for break in or an engine that likes warmer plugs or a cold day. Most of the time a c6tgc is most likely the most true medium plug although it's a pretty thin wire with a smaller hole and it does last a tad bit longer than a 97t not long enough. it can be tough to say for a fact which plugs last longer due to conditions of running, engines, etc.. but the c6tgc is a good dummy proof choice for sure. In hot conditions with low humidity the c7tgc is a great choice in hard running engines like the p5 and 7 ports and the btt 4 ports seem to like the c6tgc all the time or my personal favorite the 99t. Too bad it's not made anymore or at least to my understanding. I think the p3 plugs are too hot and burn out faster than a 97t. If your just stubborn and have to run an OS I would use a p4 plug.

I have been running a plug that ran the last main for practice and qualifying and putting a fresh one in for the main. saves plugs and seems to work really good like that. It would be nice to see a few more plug choices for Nova engines. 10-12 bucks for a plug is pretty steep for swapping out plugs every day of running. The 87t and 99t plugs seem to last longer than the 97t. the 97t is a bit hit or miss but the other less available plugs are awesome. why they keep 97t's around and drop the good ones I don't understand.

A c6tgc is a good plug if its going out before a full day of running something is most likely wrong. You should be able to get a full day of practice quals and a main from one. No more than that. Check the plug if it's distorted or fried check ur tune and replace it only after making sure the engine is not to blame. Throwing plugs in an engine that is dirty or tuned wrong or has issues will only kill more plugs. Hot days combined with large fast tracks can cook a plug quickly so in those cases change em out or go to a cooler plug like the c7tgc but only if it's dry and hot at night I switch back to c6tgc.:nod:

race ready plugs
 

Im'e an Ammeter ,But I often do this .First i get a race tune with old plug ,then fit new plug of correct heat range ,,run a few laps to get back up to temp ,and allow the fuel additives to coat the plug ,inspect and store for A Main .The previous comment about heat cycling makes sense also . Plug life is governed by the amount of Cadmium coating the filament ! This is because when Methanol comes into contact with certain elements ,incl Cadmium Spontaneous Combustion is achieved .The amount of time the plug is exposed to methanol governs the life of the plug . Therefore the higher the RPM the shorter time span .Rich Mixture ,short life ,plug wet after shut down ,ie stopping engine by exhaust,which leaves the combustion chamber wet ,short plug life .
this is provided youre tune set-up is spot on :weird:

It's an onroad thing, something the pros starting doing during Nova's dark period of crappy glow plugs.

I always run Werks #5 and sometimes a #6, never had any issues with it, and last long.. Never had one fail I just replace them when I think its time... And that gets longer and longer :lol:

It's a good idea to go through one tank each on any new plug, before you bring it as a spare.. some plugs are duds right out of the box.. and some last only a lap or two. So you want to weed out the bad ones, before trusting them with an important task.

I know this question has been asked and debated to death. Can I use OS plugs on P5 engine? I am willing to take the risk of not being able to use the Nova plugs again. The Nova plugs are expensive and out of stock on amain. We have a race coming up and pals have OS plugs. Just need to know if it will seat well and won't make the engine run erratic?

Will greatly appreciate your quick response.

Just don't torque them like a Cummins head bolt and you'll be fine.

There is no problem using a glowplug for a gallon if it is shiny and you are on the Rich side. Should you do it under racetune, no.

I use a New glowplug for quals, one for the semipractice and semi and one for the finale With the New plugs.

but, when the glowplug, only last a qual, and you take a New one out of the same 5pack and that lasts the NeXT 4 quals, i change and that one only last the semi practice. takes another one and that one can og the semi and fianle if i am in a hurry.

last year i use two glowplugs for a race. One before freepractice to have Control over the tune for the track. This one i change before semi practice, again to keep the tune in check. It would be fine for the semi and finale without problems.

The New Nova plugs is not as good as before. That is my experience.

I just tested my modded P5 in truggy, with a brand new Werks(rebranded) clutch. 2058 Werks pipe, Nova #6 plug. It was far and away the turdiest turd of an engine I've ever run. Clutch has 2x 1.0 & 2x .9 springs (I think) Must be the clutch? It basically felt like I way running a 10T CB..(stock is 14..)

Put my RB Fire 11 in (same pipe and a stock AE clutch), and it kicked axx.. What's going on here?

Try a 9853 or 9886. Wrong pipe
