We've logged hundreds of high boost dyno pulls using water injection, we found putting the water pre-turbo tremendously limits compressor flow by displacing air molecules with water plus slowing down the turbo rotor speed as the compressor crashes into heavy water particles. We understand that the water in this session was an after thought and the data is great, but next time put the water into a nitrous tank and use nitrous or CO2 to pressurize the tank and regular nitrous solenoids and nozzles to inject it post turbo. You'll still incure some airflow penalties displacing intake air charge with water, as the exhaust will go richer when water activates, but you'll get way more out of your turbo system injecting all water post turbo. Great video, thanks for sharing data and educating everyone!!

Love both what this video has shared, but also what you've added here - definitely stuff that got me head scratching about it. Something I've wondered about in addition to what you've mentioned here, I've often wondered how much benefit there would be to actually just venting some "unneeded" intercooled boost air back into the compressor in the same way the water is being done here by way of that exact same boost - just without water in the way. In my head if a small amount of 60psi+ air that has been cooled from hundreds of degrees down to closer to ambient temperature is then allowed to expand to ambient at the compressor inlet, the resulting speed and temperature would potentially give a bit of air-entrainment effect but at the least possibly do a slight bit to drop the pre-turbo air temperature while not putting more load on the compressor by offsetting useful air. Has this ever been considered or tried? I feel like anti-surge ports are a bit like a passive version of this but with some strategy to it when the compressor is operating in an efficient area there *COULD* be some benefit. Tho on that note, I'm not sure if this car actually is intercooled

So much knowldge and wisdom in one room, fascinating to hear all the real intricate details about tuning!

I am just a basic truck guy trying to build a 49 Chevy with 1200 horsepower. I'm still short a turbo. All I keep saying is, man you spend more time on the dyno than the track or the street. But now I get it. You are all about r&d. And by doing so you have gained major horsepower with less boost. I have followed you from day one when you powered up your windows at the track.

So good. $500k worth of equipment and checking plugs/drilling jets... 😄 Back in the 80s, I was using stock Toyota mechanical secondary carburetors on turbo engines. No jets were available, so...yep. Bigger drill bit. Loving the logarithmic combustion analysis.

Your water nozzle is dribbling after you let off the throttle. Tank needs a small bleed hole drilled up top to allow the tank pressure too drop as boost drops. Exair makes an HVLP spray head that works well and zero compressor damage. I love this series of tuning videos! Hope to meet you gurus some day and chew the fat! 👍 So much knowledge

We use a 250htz high speed value connected to the number 1 fuel injector. So we can progress the water with the fuel. Drag car not so much.

The check valve in the system turned out to have a higher pressure than the boost at which we wanted the water to be active. So I took it out of the system and moved the tank down to the front wheel so it wouldn’t gravity feed. The concept was to see if the water was a workable solution, and later we could address control and the leaks etc.

The way the editing was done it makes it seem as though closing the wastegate is what made the engine fail the gaskets. But in reality the wastegates were shut several runs before. What made the engine fail was a massive jump in ignition timing to try and get the CA50 values in the cylinder pressure analysis to be at their optimum angle.

Grats! Very interesting journey. Good luck in the future.

As a tuner, seeing the pressure graph of preignition vs detonation is very eye opening. I have very limited experience on Methanol, and I honestly didn't know that preignition wasn't always detectable on a knock sensor. One stupid question though...I'm guessing preignition is still audible through electronic det cans? Absolutely phenomenal work to everyone involved, what a badass project.

The water injection used like this is new to me. I think I have a grasp, you are using the water in a way to cool the overall combustion mixture to allow more boost which adds more heat. This is your way of cooling it. You were then able to keep adding boost without overheating. I really was impressed in the R&D done with the valve train with the cameras and actually seeing the components deflect under load. The Spin Tron is an incredible piece of equipment. It allows full load on components without using the combustion process as the power source saving money and much safer pull after pull. You guys are an intelligent group that function well together, I love all of it.

Yes, but not sharp like knock. It's a deep rumble. Problem is...if you get into it far enough where you can hear it, it usually ends in a hole in a piston before you can pull it back.

This is the style of nozzle I use on my evo 8. Adjustable needle for water flow, works well. Youll need a solenoid to control this one on the water inlet. Hope this helps. I believe i have a short vid on my channel of it operating

Pre turbo water injection is the best way to make a small turbo lag like a big turbo and make 80% of its rated max power. Watch the turbo speed when the water hits, and the EMAP climb when the water acts like a brake and slows down the back wheel. Need to do post turbo injection and you’ll see benefits without the losses. Definitely some cylinder pressure to turn the radiator into a balloon. Hopefully the block and head aren’t too badly lanced.

Nice work boys. Max love from New Zealand. Thanks for the wicked videos. Im off to slap a boost referenced water injection on my car :)

That dancing fire extinguisher was a hoot.

The misfire on the passenger side started a backfire that pushed a boost spike into the engine, again on the passenger side, blowing out #8, because the boost was a pressure spike from the backfire. I recommend a New design head with dual spark plugs, double the coil size, and/or increase dwell. That misfire and boost spike cost you an engine. A pressure sensor at the compressor outlet with high enough response time to shut the engine down before the pressure wave reaches the TB could be a viable strategy to prevent boost spikes entering the engine. Blew out the spark. Shove a Gopro in the intake and see if the intake is puddling with water.

ONE PRO TIP!!!!...on these cars....add a pressure sensor on the radiator and an air pressure sensor in the sump..to cut the engin before major damage occurs.. broken head gasket = excessive radiator pressure... boom cut out... broken piston rings = excessive blow by....excessive air pressure in sump from head gasket to oil ports.. boom cut out before major damage.... HOPE YOU READ THIS.....PS Excellent progress..

@@RG-lq9de I don’t bother with it any more we used to use it in the sport compact stuff as it had water jackets but in every case it had the gasket out or the head lifted and the engine damaged even with the cut(we just turned the limiter on to shut it off) The problem seems to be that when you have one running at this output level when it decides it’s done, it’s damaged itself already when you see the data in the trace. It’s a functional solution as long as you are “tickling” the edge but when you run past it as we did here, you are not stopping it from getting hurt.

Dyno Numbers are cool... Winners circle pictures are ALOT cooler!

You need proper air atomiser nozzles if you aren't going to run high pressure pumps for the water. Spray systems and many other do them, even some paint spray mixers would be a significant improvement.

What are your plans on addressing the water not making it into the turbo and onto the ground, great pulls by the way.👍

any thoughts on whether any of that water could get under the rear slicks during a run? Especially some puddling during shutdown?

i love this channel! learn alot and very very impressive numbers!

Is there a point where the static compression doesn't make a difference when you pass a certain boost threshold love the knowledge your letting out

Looks like a funny car 😀

I would like to know what was the intake air temperature charge before the water injection. Verses after the water injection. How much did the water injection lower the air intake temperature. That is probably the problem you're having with the detonation. Is the air intake temperature is so hot. Due to not having an intercooler on this vehicle even though it is on alcohol or methanol whichever fuel you are running. You're already at the detonation threshold

My total wheel hp is your wheel hp gain. Good work fellas. Definetly did not see the water injection coming, im intrigued. Might have to go pick up a super soaker for this little s400. 😅

If theres a catch, maybe its what rpm to turn it on? Cooling is one benefit, but also the expansion rate of water to steam is phenomenal. I would think water off at idle allows moisture bake off from the crankcase, and maybe instead of jetting, a stepper motor & needle valve combo might be tunable with its own rpm curve?

Bro, I don't think Ron Davis is going to warranty that radiator! I've seen a lot of things, but that radiator came apart in unexpected ways! And this not repeatable power......well if you have a "trailer full parts", I guess it is.

Water methanol does not have the ability to absorb as much heat as water itself. Thanks for checking out our video 👊🏻

what's the air density post compressor? it doesn't look like you use a charge air cooler- wouldn't that help with detonation/knock?

Shane has the best explanations because he just knows.

Its not the only thing, but wave theory knowledge does enhance an understanding of detonation events. In the radio frequency world, a properly tuned & maintained system works. But, a damaged tuning coupler or waveguide and power is reflected back into the system. An engine cannot avoid reflected power of a sonic wave, only cope with it - its an exercise in much the same phenomenon of a standing [radio] wave. So lets pick the simplest example of what most of us have likely seen: waves on the water. Sometimes they are traveling different directions, and when swells intersect, the combined energy results in a high point. In an RF system this is called standing wave - as a ratio. So why the mention of RF? Because to test a system without broadcasting, a dummy load is used in place of the antenna. For a waveguide, that load has an internal pyramid like taper that will absorb/attenuate the energy and prevent big power reflection. The thing in modern head design that does much the same thing to sonic waves? Chamber "softening" - something between 1.5 and 3 degrees taper seems to be what works from what I can gather... but a designer I am not. Prior to this innovation, head porters/designers would adjust chamber shape if a design proved detonation prone, noting the sonic wave outruns the flame kernel and reflecting/recombining to the point where it, combined with other factors of heat & mixture, allow one or more extra & unwanted combustion points that cause peak cylinder pressure to happen too early vs crank position. Fighting/fixing detonation can be a long battle... very long, or much of this would have been well sorted in 60's. Every combo has its limits... you guys are doing great - love the tech.

A true test will do like SICK WEEK, DRAG WEEK or Midwest Drags with it. See if it can take the stress of a Drag n Drive. The water isnt new. I did it on a car i raced to cool the fuel air mix going in and the little moisture raised my HP. Kind of like a water/Meth injection. Everyone knows cooling the air going in helps knock and hp. Thats what you are doing

how can you have detonation after the spark event? isn't everything in the cylinder burned after the spark event?
