Lightbulb Aquamist + Syvecs Integration

I'm forever getting asked (phone, email, internetz) about why I choose to only use the best parts, its simply to do with making the power plant reliable and durable, not cause I get paid to say so with free/subsidized product/s

The best way to show the general public this is with an example off a real car, I keep saying unlike the YouGag bloggers, Forum vendors etc, IE = shit talkers (with pay to play endorsements), these cars actually work and still run

What is important is the integration part, this means that any system on the vehicles engine needs to be properly developed to counter any and all eventualities. This applies to any sub component on the engine that is needed to make it run, be that a fuel injector, ignition coil, lambda sensor....... think of any input (sensor) and output (actuator) in general speak.

The water injection system has to be treated the same way, to not do that is a mistake which I can say to you from personal experience is how it is. In the simplest forms strategies to properly control ANY engine can range from levels of action to a fault (system out of range or not operating) the logic is proprietary and wont be shown 100% (sorry stalkers! fuck you!) but even the arse clowns can take some notes here !

Turbo Charged:
* Reduced boost level
* More excess fuel
* Ignition timing adjustment (Knock/Detonation control)

Think of this as a multi layered approach with the ultimate sub set of Knock/Detonation control being the final *always active* defense to the engine, and this is where not all engine controllers (let alone programmers!) are created equal. For WM50 application you want active control on an individual engine cycle level @ say 9000rpm, this requires a quality system ! if anything is out then your engine will continue to live, no excuses. Below you can see the input to the ECU provided by the Aquamist and then the action taken by the control unit to manage the engine. NOTE: you can do this on a whole engine approach or if its a multi cylinder deal (most are!) then depending on instrumentation/inputs obviously on a per combustion chamber basis, most of mine are that way but its a case by case deal. The final arbitrator is DETONATION and even on the most basic application using Syvecs/LR this is controlled perfectly which avoids an over enthusiastic calibration setting combustion event based failure. This is a high percentage (I would say easily the highest by some order) cause of needing to get out motor, and why lots of idiots put in a boat anchor rather than sticking with the superior low mass high power density turbocharged power plant.







Keep in mind, we have never ever lost an engine running a Syvecs/Life Racing ECU, never! why? probably 1/4+ century of water injection knowledge and its reliable implementation using the best parts. Ironically there is always some parrot screaming out, "but what if it stops working!" well cuntox the facts are I see more daily issues with main fuel system fuck ups 100 fold than I ever do with even an archaic WI system, and that is a fact most don't care to acknowledge.

Lightbulb Re: RICESP Water Injected RX7

One of the other things not spoken about here is the efficiency of the charge cooler, I have done lots of experiments and real world tests of this with.

A to A
W to A
chemical inter cooling

One of the big benefits of the WM50 system is you can use it to greatly increase the eff of the charge cooler, with none of the negatives of running a W to A, or No2 etc.

Nothing new though, it was used to great effect until it was banned in F1 after 1986 season (see below).



When I get some time I will put up the actual figures of conventional systems v's superior WI spray enhanced set up's Keep in mind this augments the internal injection of WM50, you end up with exceptional density gains with none of the associated negatives of the main stream solutions used by those who are not so smart

Default Re: RICESP Water Injected RX7

When water injecting only use the best ignition systems, if you are trying inferior inductive based crap then lord have mercy on your stupidity

Taking EGT probes and making them the best they can be, put these up against anything anyone else makes and will run rings around them! Some tricks to using these properly too, take a look at the real knowledge linked above and on channel

Exclamation Re: RICESP Water Injected RX7

In my latest series of valued resources I put this up, well worth watching for anyone who wants to learn quality qualified information v's the plethora of Arsebook online shit out there ~!
https://www.youtube.com/watch?v=kDgm...ature=youtu.be

EGT, TIT, fuel mixtures, how engines work, fundamentals of internal combustion....... if you want to know don't miss this or skip through it

Exclamation WARNING on shit quality ECU's

PLEASE
PLEASE
PLEASE!!!

https://www.youtube.com/watch?v=TEusfXCHoHI

^ DO NOT run garbage like this! Every farking week I get asked, 'oh but my tuna tells me to use this and its all he uses' my response is find someone who is competent! Don't sell yourself short and limit yourself cause your monkey cant learn anything, only train himself to use sub standard rubbish.

Especially on a water injected car!!!!

There is no end of arse clowns out there especially these days, people with a pay to play 1 week certification and a few shitbox cars to their name, then pretending to be the latest and greatest expert on everything...... don't fall for it please seen this too many times.

It's quite sad to know that there are great ECU's out there but they get drowned out by the marketing departments and propaganda machine that would make Adolf Hitler very proud!!! stay away from the shit please, go to a water injection specialist and use the computer and parts to complete the set up as they dictate, it will work and will have zero excuses, and you wont get thrown under a bus years later when they walk away from their ECU affiliate as LINK'd above pictures in the vid description. Remember shit in = shit out.

Smile Re: RICESP Water Injected RX7

Hello Peter,

What kind of water/fuel rate you usually run?

I run your old style pre turbo setup on a 13B w EFR83 and RON98.
It flows with the metering screw fully out 272cc at 1 bar, 370cc at 1.5 bar and 420cc/min at 2 bar.

At 3250 rpm 1 bar boost this nets me around 50-60% of water to fuel rate (mass based) running lambda 0.8. The car has IGN-1A coils and a bit surprisingly lights this just fine. Logically at 6500 rpm running double the air and thus fuel the water rate drops to 25% approx.

Hello Mate,

That above is about what they do as you describe it. The rates I use depends on allot of variables some but not limited to the knock threshold of the main fuel supply, how much charge cooling, what can be tolerated via the ignition system to mention a few.

What you can establish a flame front on is proportional to the excess fuel ratio and how much is inside the chamber, along with the compression ratio of the engine type it is being applied to.

A rotary engine in a road application verified by my many engine dyno tests with the sort of set up you are running will give around 80bhp to 90 bhp per liter per bar of absolute pressure when all of the parameters are within range, if you run more spark lead timing it can be easier to get it all started. Typically when you are running an engine (13B) at 700bhp range and its on BP Optimax + WM50 and its set up in 'endurance' form then its got to be run with much excess fuel and when the charge filling is at its peak and associated acceptable spark lead setting, this is when you will find the merits of a full CDI set up over inductive.

If the engine is less stressed or any of the running parameters are set optimistically, say more spark timing and less excess fuel and less overall power density, then you can get away with running different ignition systems.

I assume here you mean per rotor? an NA streetport REW engine (9:1) at sealevel with xcessive LIM makes 170-180 crank hp.

Offcourse as you say depending on the knock tolerance of the fuel the spark efficiency will generally get lower the higher the chamber chrarge and charge temp.

I will post here how it turns out.

At work we ran 1 cyl DI development engine with a pre chamber, 10:1 CR, port water inj at 7000 rpm 32 bar bmep with lambda 1 and optimal spark (50% burn around 8 deg atdc). water rate 50 to 55% of fuel mass. this is could be considered state of the art but if the water stops piston is gone before you can count to 10.

I assume on this evo you could run similar water rate but perhaps are still a bit more knock limited. the burn duration of the pre chamber combustion process is very short, giving the mixture less time to knock. Do you have cylinder pressure indication system? I would be interested what kind of spark efficiency can be reached on a port fueled engine running these loads and pump fuel.
