So is the secret a very cold spark plug, bad *** ignition system, and lots and lots of fuel to cool down the rotor housing? I'd imagine that if this is were the case, it's no wonder water or alky injection is working so well.

This is basically what ive understood over the years of being in the community. This thread as alot of good information that should be R&Ded. I read from rx72c alot of his threads basically say. bad *** ignition, cold plugs lots of water. Me and a buddy was talking the other day. Im going to have A/W ic and weth/water injection. In the trunk my container is huge and holds alot of ice and its an aluminum container basically made out of one of them truck dimond plate tool boxes that go in the bed. It has a divider in the middle b/c one side is going to be for the IC and the other side for injection. I just realized whatever is going to be used for injection wether its meth/water or just water it is going to be VERY cold due to the fact theres pounds of ice next to it. i dont know what this is going to affect or how the motors going to react to it.

... and the room goes silent. This is one of the biggest problems in the racing community. I KNOW the puerto ricans and the aussies have tuning down pat however it's a secret. So us "yanks" are left sort of in the dark to figure it out all over again. where is the rotary love 
All these secrets do nothing but hold back the potential of these rotary motors. Oh well props to you guys for figuring out these tuning secrets.

no your absolutly right, but I do remember a time when it was all about what port you had, then when tuning started getting better all of a sudden big nasty ports didn't really mean anything and it was all in the tune. Same goes for many different aspects of the rotary motor that people thought this band aid or that band aid was needed but it just turned out to be tuning. I just think there is something going on in the tuning world that has gotten much better but only a few people are in the know. I mean I was just watching this thread of some guys that were getting something like 800hp on some old 13bt original motor (never rebuilt) and it had been beat to death. It's just little things like this that have me saying wait a minute, there are people running incredible amounts of power with absolutely no problems and then there are people every day giving up on the rotary because they keep blowing their motors up at 15-17psi.

This along with 10.5 leading plugs and 11.5 trailing should take care of the badass ignition and cold plugs part of the equation When I tell you this ignition is bad ***, it is BADASS! I've never seen this type of spark before coming from a spark plug. No matter what plug I have on it, 5 different sparks come off the plug and grab the nearest metal like Dracula's fingers reaching for someones neck, it's the coolest thing I've ever seen!

The one discrepancy I've seen with Puerto Ricans and aussies (and this is just from my experience) is that most aussies seem to hate MSD and stick with their crane stuff most Puerto Ricans seem to only use MSD. I ended up going with 4 crane lx92 coils and 2 crane hi-6 boxes for the leading despite my PR buddy thinking it was a mistake This along with 10.5 leading plugs and 11.5 trailing should take care of the badass ignition and cold plugs part of the equation When I tell you this ignition is bad ***, it is BADASS!

You should see some of the Puerto Ricans now that have stock cosmo UIMs going 8's in the quarter mile but yeah most of em' need some crazy thottle body with like 8 and 12 injectors for the alcohol. I've got an lt10s and running the lx92's just fine. Not sure about the lt8. You may want to do some searches in the microtech section for that. I was running stock coils on my lt8 when I had one. Maybe a twin power would do well with stock coils. I've heard nothing but good things about them.

KDR anti-detonation mod=
Metal plugs that take the place of the trailing spark plug so that too hot of a trailing plug doesn't start pre-ignintion.
This mod will raise EGTs though since you have more incomplete combustion in the engine and more combustion in the exhaust manifold.
He was just kidding around, because of the comments about used to be huge ports for power, then all about the tune for power. You forgot the anti-det hype- lol.

I've got a secret... pressure transducer sensor.. exciting eh?
pressure is directly related to power output - its a little expensive but we're working with the same engine-types over and over therefore a good investment.
often i've heard tuners "tune up to slight knock then back a degree or so".
of course i'm talking talking about the backyard PFC tuners.

Orly? Show me any rotary tuner that is willing to show you how to tune, to share "the secret". It seems that everybody is focus on figuring the "magic tune". Have a talk with the those experts that are willing to give you a few mins, they all say the same thing, there is no "magic" to their tunes...

Wow, that comment hit home really hard. Currently looking into the new AEM Series 2 EMS and upgrading everything that will be going with it (Coils, Mitsubishi Knock Sensor, EMS speed based controlled boost, 30-2 crank sensor setup, integrated AI control, etc.). After looking at the control features on the new and old AEM software makes me regret using a PFC for so long. The AEM with it's overboost, knock feedback and closed loop features would have saved my last three motors. 
For just startn...

Thats what i was thinking and my uncle said the same thing. It's kinda common sense you see aluminum corroding all the time. I just thought well i won't even have the setup long enough for it to even do that, the way things go right now seems everyones always changing diff setups and doin diffrenet experiments. If i think im goign to keep the car and keep the setup the way it is then ill figure somethign else out im sure.
