As I stated earlier, I run my Nova Rossi based engines (Mugen, RB, Nova Mega and Top, most modified and ugly fast) in very hot weather.
I use 30% O'Donnell fuel with 0.3mm shims under the head.
For plugs I use either MC 59 or CT5F which are the hottest plugs of their kind.
I have never had a problem with pre-detonation, neither has any of my engines developed a hunger for plugs (I actually ran a CT5F turbo plugs for over 3 month, racing every Sunday)
Usually I run them between 240 and 265 F.
So, all theoretical knowledge aside, these are real world experiences that are prooven to work.
Next opinion please!
I'm a bit confused as to what constitutes a "Hot" Turbo plug.
The
Novarossi site says they have a Hot range and a Cold range of plugs. Then, each of these "ranges" have various hot and cold filaments available.
The C.5TF is a cold body with a hot filament.
The C.5TC is a hot body with a hot filament.
I mean, wouldn't that make the C.5TC the hottest plugs of their kind?
Or did you mean the hottest of the Cold range?
Here in Oz at the end of January the ambient is likely to be about 30ºC and we'll be using 16% nitro in a Nova 3-port .12.
So, the question is . . . . which plug?
