I'm searched the internet and haven't been able to get a clear answer to my question so i'm hopping someone here can help me. I'm not new to nitro rc as i've had many small block cars over the years which primarily consisted for traxxas 3.3, os .21tm's, and OS .18s in various vehicles. But I've recently gotten into larger RC vehicles mainly 1/8 truggy and buggy. I'm been running mostly RTR vehicles that came with either a .28 or .21 motor and they all came with and recommended cold plugs. All these engines were of course standard plug engines (as there cheaper RTR kits).
I've started hitting the local track and wanted to pick up some more performance and explore higher end motors which all seem to come with turbo plugs. I understand heat ranges and when to his colder/hotter plugs and for the most part I run R5 cold plugs in most my engines with an exception of one force .28 that seems to love OS 8 medium plugs. What I don't understand and I'm not sure if I'm missing anything, is if the heat ranges and the general concept of large engines higher %nitro requires colder plugs, why does it seem all turbo plug performance motors come with a p3 hot plug assuming most racers will run 30% nitro? Wouldn't running a hot plug on %25 or 30% nitro cause detonation? I've always read you never run hot plugs in .21 or larger engines. It just seem odd a .21 standard plug motor comes with a cold plug while a similar .21 turbo plug engine comes with a hot plug. Is there something I'm missing between standard and turbo plugs when it comes to heat ranges?
