BOOM???

Will running MSD coil packs(hotter spark) and an NX wet kit with 2 stage colder plugs(as I should) cause any damage (i.e. detonation)

if you're worried about detonation (which shouldn't be a problem til you get into the large amounts of n2o) you should look into a programmable msd that will allow you to retard the timing a few degrees... (which i believe is part #6211)

beyond that, running nitrous on any engine is stressful..... it's just a matter of how knowledgable you are and making sure it's tuned correctly

not really planning on running more than a 35 shot daily 50 shot on occasions and a 75 on very rare occasions. But I was thinking about this at work and said I might want hotter spark to burn the mixture more thoroughly. And as you said about the plugs in Ryan's a platinum plug acts like a glow plug which= no good, but if I run say copper than a hotter spark would be good to burn the mixture.

a plug's heat range really doesn't have much to with how hot the spark gets

Quote:

Q: What exactly is a spark plug "heat range"?

The heat range has nothing to do with the actual voltage transferred through the spark plug. Rather, the heat range is a measure of the spark plug's ability to remove heat from the combustion chamber. The heat range is determined by the insulator nose length and its ability to absorb and transfer combustion heat, the gas volume around the insulator nose, and the materials/construction of the center electrode and porcelain insulator.
In identical spark plug types, the difference from one heat range to the next is the ability to remove 70C to 100C from the combustion chamber. A longer the nose on a spark plug forces the heat from the tip to travel farther before it is absorbed by the cylinder head, which reatins more of the heat in the plug tip - making the plug "hotter" than a similar plug with a shorter nose. Engine temperature will affect a spark plug's operating temperature, but not the plug's heat range.


the only way to achieve "hotter" spark would be to upgrade ignition to something like an msd setup

just stick with the ngk tr6 #4177, you'll be fine

and...

the reason you want a colder plug is because when nitrous is introduced to the chamber, things get hot real quick

so the faster you can get rid of the heat the better, but this is also within reason

and most have come up with the happy medium with the ngk's

Hotter spark (higher voltage) is perfect for a N20 motor. It takes more voltage to create a spark as the cylinder pressures rise, so stock ignition systems eventually max out. The important thing (as meltdown said) is go with a cooler plug to get the heat out quicker.

Is that the part number for NGK's on Cavy's? Cause when I was looking for them on a corolla all I could find at Adanced Autoparts is stock NGK's but the tr6 is a colder plug if i'm correct. So on the listing on their computer would it just say NGK TR6 Copper blah blah blah?



Re: BOOM???

yeah, the plugs themselves aren't SPECIFICALLY made for cav's but people know that they work, and work well

i wouldn't know where to start with a toyota sorry... but the same principles still apply, maybe more or less drastic considering the application....

Tr55 is stock, so a step colder would be tr6

but who knows what a stock plug would be for a toyota???

i doubt it's the same as our cars....

BKY5es blahblahblah..... there's a lot of them. None I've sold have been the tr series.

I don't mean daily as in everyday use but as in 35 shot for whenever I feel like using itduring the course of the week etc.
Cody: what would I do without you
So should I even bother getting the coil packs. I'm asking cuz some guy I know at work wrecked his cavy a while back and said he pulled them off. That and he wants like $50 for both.



Re: BOOM???

I'd go for it.

are they stock coil packs or aftermarket???

if they're stock... then no (duh)

and i'm honestly unsure of how much an upgraded ignition on the 2.2's would run, so i couldn't tell you what's a good deal... sorry

They're MSD brand coil packs that fit in the stock location. I looked them up on highrev.
