guys with Progressive shots... what type of plugs are you running with all that heat thats being created?
i have ngk tr6s i believe and i just bought the FJO controller from Dave.
and I was going to change plugs so they dont melt.

thanks

How much are you spraying? If you spraying no more than 175hp, I would say that the TR6's will be fine. No need to go colder unless you are spraying over 200hp.

 

yea thats what i got i believe.. but i was thinkin since im aiming for 475-500 rwtq from 3000-5300ish rpm. all that cylinder pressure is bound to add ALOT of heat.
didnt know if itd melt the ground strap.

it will be a 175 progressive shot which will prob not get to the full 175 shot... maybe at 5300 + rpm.

 

TR6 will handle that size shot. The colder you go the more likely to fowl the plugs.
And you will suffer low R.P.M. ignition 'Quirks' .
