cooler plugs!
Turbo Mini Forums

running Champion N9ycc

in the champion range does the lower numbers denote!
a cooler plug?

& what about the other brands NGK or Bosh?

its slipped my mind! must get back on the cod liver oil ....lol

thanks guys

bosch=W8LCR
Champion=N9YCC
NGK=ZGR5A
Beru=14-8LUR

All the following are the same heat range

I got n9ycc in mine

Champion plugs higher number hotter

ngk plugs higher number colder

Metro turbo weekend driver,Mini turbo in the making again!

Yes mate

1293 Turbo mini

How does C57CY compare to N9YCC I wonder?

What is a C57CY ?

1293 Turbo mini

Similar to the QC57's...

:)


It's the plug I've been using for the past 4-odd years after struggling with POS NGK units...

Who makes C57CY /QC57 ??

Champion

Here is the champion ones

with MJ you need resistor plugs, thats correct Peter, Ive checked it out :)

I ran qc57c's Ran for a whole year without problems, although I did find if you wetted a plug, it was never happy after that,

going a bit OT, what plugs do you guys plan on running in the k series head?

ithink you may find pete ,that the need for resistor plugs actually comes down to a need for some degree of suppresion of the emf caused by the spark ,if you can do this with the ht lead ,eg a spiral wound stainless coil ht lead ,then i have found on another v8 engine of mine ,i can run a normal plug cos all the suppression is done by the self choking effect of this sort of ht lead ,with minimal resistance ,this engine runs a msd7al2 multi spark capacitive discharge box with enough spark energy to cut thruogh a credit card ,along with a accell dfi programmable fuel injection box ,and i have no emf probs ay all ,and thats with some sensor wires not that far from the ht leads ,which are 8.8mm accell spiral wound ones .regards robert.oh fwiw i allways run ngk full terminal plugs and not the v type or iridium ,i have tried them all and think its just as good to run normal ngk ,whether on the bike, the mini, the v8, or my propane van , the important thing is good spark power ,and a good spiral lead .

Medusa + injection = too much torque for the dyno ..https://youtu.be/qg5o0_tJxYM

Pete, just looking at that plug chart, do you happen to know the thread size and reach of the standard plug for the k head?

Team Racing

ok ,my take !!! yet again !!! i think this subject of resistance is futile ( gratuitous borg quote). the resistance is in the cylinder at pk cyl pressure or at a lean mix or a comb of both , but once the spark is intitiated the resistance can create a longer lasting spark cos the coil cant discharge all at once(any male having gone though puberty will relate to this problem)
so if you have a cylinder that needs a long spark duration ,this is benificial ,but if you have a cyl that needs a bog off hot hard(oh dear) spark ,then any resistance can create no cylinder fire off at all ,or what is technically known as a ''missfire''.with the multi spark ignition ,the capacitive discharge makes a hot fast short duration spark ,that repeats over about 20 odd degrees ,so you get duration and intensity ,without additional resistance to prolong duration of spark..

Heres my take on resistor plugs.

Electronic injection/ ignition no resistor plug = engine run poorly, not to mention nextdoor nieghbour complaining when they cant watch Corenation St due to white fuzzy lines across the tv.

Though as said before if you can surpress the interference else where there should be no reason not to use non resistor plugs.

QC57C's

Have run them for four years.
As Jim says - get them too wet, and they don't seem happy - but they do work at least.

A session in the oven and a doing with the shotblaster seems to solve a lot however!

iam going to go 2 grades lower from N9Ycc to ..... N7Yc & see how it goes
