Great Vid, look forward to seeing the outcome. Planning to change plugs and coils soon as I'm swapping to DAW S2+ turbos and there seems to be mixed opinions on what to run.
How much power you making? Jw cuz Im like semi fbo just stock fueling. 1 step plugs, BMS inlets and outlets, DCI, down pipes, 7.5in stepped fmic, and charge pipe w Tial bov.
0.46mm on 2 step colder plugs is what I use on 30 psi . But that also depends on what mixture (afr ure using at what rpm/boost level )and fuel type. No magic bullet honestly all depends on what ure tuning (fuel / mixture / boost level) and what logs look like. Edit : repeating myself above but really there's too many variables that go into making that decision.
@@ZeroTo60Tube I have some kumho ps91 295s in the back now lol. Need grip..should be testing 1 to 2s soon. I'm just too slammed doing customer stuff to even drive lol
So the general consensus that I read about and was told was for every 100 or so hp you increase the engines performance by you should increase the heat range one step.. that being said I've been running my junk on one step colder plugs than factory since the beginning without any issues (yet)... a bigger plug gap will burn more efficiently than a smaller gap providing there's adequate coil available where the smaller plug gap will not (blow out) under higher boost but will not burn as efficiently under low boost power levels... (at least as far as I'm aware) either way good vid keen to see you wind it up some more amd smash your record 😁🤘

The superceded NGK 1 stage colder plugs were the 95770 (ILZKBR7B8DG). These were replaced by the 97968 (ILZKBR7B8G). What difference the 'D' makes in the number, I am not sure.

@10:50 keep in mind outlets are different for RHD and LHD cars. The rear turbo has the cold side twisted a bit, and also the wastegate actuator sits in a different position. Also RHD cars have the steering column going right by the rear turbo outlet, therefore making it high-flow is a bit sketchy.

I run the 97968 plugs and have no issues on E40 and the 17t's. I don't see 20psi, so that does me fine. Gapped at 0.21. Having said that, after your video I may re-think that position 🤔
Do you know what yours are gapped to?
