Show me your water/meth setups on the 5vz-fe

While waiting for money to show up for the engine to be completed, I'm starting to plan all the other mods to help get the most out of the S/C when its all back together. So just wanted to see what others have done, like what injector you guys run to make the most out of the s/c.
My plans are to get an older Tacoma washer fluid tank and put it up on the passenger side wheel well where the ABS would be if i had it... then a kit of sorts or a DIY with a factory washer pump from a vehicle with headlight washers.. (should be a 75 psi pump in most cases)

 

This is the tank i'll be using most likely..

 

What are you doing? Installing headlight washers?

 

no. Meth injection for supercharging to effectively raise octane and more importantly lower intake temps after the blower.
Headlight washer was mentioned because they tend to use a higher pressure pump for the fluid than the windshield washer fluid, yet its compact like the washer fluid pump on the trucks factory.

 

Any updates, I'm looking around for a setup for my truck

 

Bump

 

i wont have any updates for a while. engines still not back in the truck lol.

 

Well maybe I will have mine installed before u

 

Check out cooling mist. I'm not well educated on methanol injection set ups but from what I've read they are well ahead of the rest. They use high pressure pumps (150 psi?) and "super atomizing nozzles" which are safe for pre turbo injection from what understand but also just provide a more homogenous charge.

I ran their autolearn kit on my sc and it was great. Has adjustable upper and lower brackets with a linear duty cycle progression of 10 stages between. The "failsafe box" is over kill IMO, it would be nice for a newer more automated car but on these older trucks its a but redundant. I'm certain they have a progressive kit without the fail safe.

I tended to get away from meth injection once I installed the turbo. Since I had more tuning capabilities with a piggy back and larger primaries I opted to make up the difference in the tune to avoid refilling the meth tank. On that note I'd recommend the largest tank you can fit. @j0shu4 is making over 300 whp with pre turbo injection so if you're planning on keeping the kit when you make that switch I'd recommend dishing on a nice kit to feel secure using pre turbo injection which I'm of the belief is the most effective way to use meth and a turbo in combo.

 

@Empty_Lord

I inject meth and so does @GioGuitarDude. It's pretty basic stuff and can be done for relatively inexpensive. My pump and tank are in my bed box. I run a devils own kit with an aem failsafe. I'd recommend the aem kit as it comes with a failsafe. I feel fail safes are important because you know for sure when your methanol is pumping. Its basically an impeller that runs just before the nozzle that measures the actual line fluid flow and gives you a reading of gpm (gallons per minute) or ml per hour on a gauge. There's differing flow rates and measurements.

 

Youll notice when your not injecting your afr will be a couple points off. I forget I think it's higher without it someone correct me if I'm wrong. So the main thing about meth is it lowers your IAT. That's about it. Cleans out the chambers too. Doesn't really add fuel though.... I just use $1.59 gallons of windshield washer fluid.

 

My tank I use is from a Jeep Grand Cherokee I found in the salvage yard. It's 1 gallon and lasts a good bit depending on how long I'm in boost. Any other questions let me know

 

Got my kit installed, snow progressive kit, my AFR could not be more perfect all the way across
the rpm range, my torque on the Dyno is 270 REAR WHEEL TORQUE at the rear wheel at only 2200rpms,
At 6000 feet, I can't make this engine ping even if I try )

 

Nice low end tq. You can make it detonate if you really pushed the timing up. My DSM runs e85. Now that stuff is really hard to detonate. It hits over 32psi and 22* max timing.

 

I put on about 30k miles a year give or take, So I'm about as happy as I can be with my setup now,
I should have added one of these kits along ago.
I need reliability too

 

It's very nice. Makes the motor happy. IMO any aftermarket power adder setup should have meth injection or e85. It's well worth the investment and can save your ass when tuning.

 

Home > Gas Water-Methanol Injection Kits > Water-Methanol Gas FAQ
1. Boost Cooler Benefits (Gasoline):1. Low cost - where else can you get up to 60HP for as low as $304?
2. More Power - We don't create an intake restriction like an intercooler, and unlike race gas, we reduce intake air temps and improve charge air density too!
3. Efficiency - leaner air fuel ratio can be utilized for normal operation.
4. Easy Installation - Snow Performance systems can be installed in a matter of hours without having to remove bumpers or do custom intake piping.
5. Engine Health - Snow Performance systems effectively steam clean the valves, valve seats, and even the piston tops and intake when they inject. This reduces carbon build up.

2. Can the Boost Cooler be applied to naturally aspirated and nitrous engines?

• Naturally aspirated/high compression engines:
Water/Methanol injection allows the use of pump fuel in all but the most extreme situations which effects tremendous cost savings as well as horsepower increases due to air density increase and higher timing advance potential.• Engines using nitrous:
With nitrous, water/methanol injection allows the use of more timing advance even with large (250HP+) quantities. The cooling effect of the water/methanol inside the combustion chamber also makes for reduced peak combustion temperatures.

• Naturally aspirated/stock compression:
With naturally aspirated engines using less than 10:1 compression, water/methanol is used often in warm climates to get the intake temps lower. Benefits include: 10-15 HP increases from air density increases and full timing as well as more effective air/fuel ratios, increased gas mileage, and carbon free combustion chambers.

While power gains are typically less in stock compression naturally aspirated vehicles compared to high compression or forced induction engines, benefits can still be realized due to more timing advance, leaner air/fuel ratios, cleaner engine components, lower temperatures, and the use of the methanol in the injection fluid as a secondary fuel source.

3. Does the Snow Performance system work on a carbureted application?

Yes.
• We have systems for carbureted vehicles without superchargers or turbochargers. They inject according to vacuum and deliver 20-25 point octane gains over regular pump gas when using a 50/50 mix of water/methanol.
• Any Snow Performance system can be used with or feature the special 4150 or 4500 style carb plates as well. MC and RT series systems include the carb plates.
• Many muscle cars that previously required expensive high octane fuel now use regular pump gas with our system while getting better performance. In fact, it has been demonstrated in magazine articles that we can actually beat C16 race gas in power. These cars can use our MC (naturally aspirated) and RT (supercharged or turbocharged) series systems for a clean installation and great results.

4. What power gains can I expect?

Boost Coolers® allow for more power in two ways on a gasoline application.
• Extra octane. This allows for much more aggressive tuning safely to make more power. Timing can often be advanced 10 or more degrees in the power band. Boost can often be increased 5 or more PSI. Air/fuel ratios of around 12.5:1 can be utilized even in high boost applications.
• Better cooling of the intake air charge. We often cool intake air temperatures 50-150 degrees. This means denser air charge for more efficient power.

If these methods are used, a 20% increase in HP is possible. In naturally aspirated applications, gains of 5-10% are possible.

5. Can the Snow Performance system improve my fuel economy?

Yes. The MPG-MAX™ systems are designed to do just that. Both the diesel and gasoline MPG-MAX™ systems are specifically designed to inject a very small and precise amount of water/methanol under normal driving conditions such as accelerating away from a stop light or driving up a slight grade.

• The extra 20-25 points of octane provided allows for more spark timing advance and a leaner air/fuel ratio with the use of a programmer. Both of these factors not only improve power, their efficiency gains improve mileage as well. Additionally, many modern cars will detect the combustion of the methanol and reduce the injection of gasoline accordingly through the adjustment of long-term fuel trim values in the vehicles computer. This can directly and positively impact gasoline fuel economy. Gains of 5-15% are possible depending on how the vehicle is tuned and driven.

6. What fluid can I use in my system?

• Boost Juice®: This is the best fluid to use and is Snow Performance’s 49% methanol, 51% water mixture that can be shipped to your door or picked up at a local dealer. (If you are using your washer reservoir as the injection tank, Boost Juice® is a great washer fluid – works as a de-icer!)
• Windshield Washer fluid: Only if it is blue in color and rated for -20 deg F. It should have no special additives. This means it is safe to use and made of about 30% methanol, 70% water. If it is another color or another temperature rating, do not use it.
• You can “spike” your Blue -20 Washer fluid to a 50% mixture by adding 3 12OZ yellow bottles of Heet® gas-line-antifreeze to every gallon of washer fluid.
• Mix your own: You just need to make sure the methanol is “neat” and contains no lubricants or other additives. We recommend a 50% mixture.
• Ethanol: It is not as good as methanol, but it can be used as a 2nd best option if you can’t find methanol. It can also be mixed with water up to 50%.
• Do NOT use E85 or any other fluid with gasoline mixed in. It will destroy the fluid delivery part of your Boost Cooler® and instantly void the warranty.
• Isopropyl/Denatured Alcohols: These can be used, but are not as good as methanol. They have a lower BTU, or energy content, and a lower latent heat of vaporization (fancy way of saying how much heat they absorb) as well as a lower octane rating compared to methanol.

7. Why Methanol?

Methanol is a very high octane fuel that is extremely resistant to detonation with an excellent cost/benefit ratio. Its high latent heat of vaporization also makes it an excellent air charge cooler which means a denser mixture and more horsepower. Because of these characteristics, it suppresses detonation more effectively than ethanol or iso-propanol although they will work in a pinch. It is toxic and should be handled with rubber gloves in well ventilated areas only. Care should be taken to avoid skin contact.

8. Where can I purchase Methanol?

• Snow Performance sells 51/49 water/methanol mix as Boost Juice™ (see products). If this is used exclusively, Snow Performance can lifetime warranty a system so long as the free registration card is sent in soon after purchase.
• Methanol can generally be purchased where racing fuels are sold. Also, most gas line dryers like "Heet" are simply methanol. Suppliers of industrial chemicals can also supply methanol for a very reasonable price. Ensure that the methanol is "neat" and therefore has no additives or lubricants added by the supplier.
• -20 degree F rated, blue windshield washer fluid is acceptable for use as well, and is available at most service stations. Although some fluids rated to under -20 degrees F contain glycol and other copolymers, most windshield washer fluids are up to 40% methanol. Try to find one that displays "contains methanol" on the label and is good to -20 degrees F, with no additives or special ingredients and is blue in color.
• Methanol can be purchased on the web atwww.worldwideracingfuels.comandwww.hiperfuels.com.
• Additionally, many sprint car drivers and circle track and drag racers use methanol as a primary fuel. They often have methanol on hand and will even sell methanol that has been un-sealed for a long time at a very low price. Just be sure that the methanol has NO additives or lubricants (such as top lube), as they are not needed and can damage the pump.


9. What ratio of water/methanol is recommended?

• A 50/50 ratio is recommended. This has been demonstrated to be the best for charge/air cooling, excellent detonation control, and safety.

• Ratios of anywhere from 30% to 50% methanol work well and deliver excellent octane gains and cooling.

10. Can I use pure methanol?

While all components of Snow Performance systems are designed to be able to handle pure methanol, it is not recommended for a number of reasons.

• Safety: Pure methanol is easy to ignite witha low 140F degree flash-point and burns with an invisible flame.
• Performance: Water absorbs almost twice as much heat as methanol in the intake and inside the combustion chamber. Water cannot be flash-ignited, so has what is almost an infinite octane number. In the government studies for WWII piston-powered aircraft, 50/50 water-methanol was found to be the best fluid to use for auxiliary fluid injection.

11. Do I need an intercooler with Water/Methanol Injection?

Up to approximately 30 psig of boost, water/methanol injection (using 50% methanol) will provide all the density increase/detonation control needed in most applications. Of course, intercooling and water/methanol injection would provide even greater benefits, especially beyond 30 psig of boost. Most air-to-air intercoolers are only 50-65% efficient. For example, with 11 psi of boost and the resulting 120°f air charge temperature increase, an intercooler reduces the air charge temperature only 60 degrees. Also, an intercooler will reduce boost 2 - 4 psig. on average.

12. Why not use a windshield washer pump?

• Water/Methanol must be injected at above 50psig to properly atomize. Lower than 50psig causes greatly reduced air charge cooling as the result of larger droplets and their reduced total surface area. Also with inadequate atomization, there is a greater propensity to quench combustion resulting in a loss of power.

• Snow Performance systems also regularly inject into charge air passages at 40 psig or higher boost pressure, and a simple washer pump will not handle that kind of stress. The pumps in Snow Performance kits are specifically built for water/methanol injection in any environment that might arise.

13. How much range will a tank of Water/Methanol provide?

This depends on a number of variables. HP, injection system, settings, driving style, etc.

• For most engines in the 200-500hp range, the standard 3qt tank will last around a tank of gasoline.
• For higher HP levels with the MPG system, it will be more like 1 gallon per tank full of gasoline. The #40016 2.5 Gallon reservoir could last two or even three tanks of gasoline.

14. I dont have any room in the engine bay for a reservoir, what are my options?


• Use the factory washer-fluid tank. A bulkhead fitting (PN# 40080) allows the use of the factory washer fluid tank as a reservoir. 50/50 water/methanol makes an excellent washer fluid. Kits for the 1.8T, 2.0T, WRX/STI, and others utilize this strategy.
• Trunk mounted reservoir. The reservoir and pump can be mounted in the trunk. 2.5 gallon reservoir upgrades (PN# 40014) feature extra tubing and mounting brackets for trunk mounting. We always recommend a #40060 solenoid for trunk mounting.

15. Where can I mount my reservoir and pump?

The pump needs to be within about 24” (hose length) of the reservoir, and as low or lower than the base of the reservoir. It is a “pusher” pump, not a “puller” pump.
• Engine bay: In the engine bay, the reservoir and pump can be placed almost anywhere, as long as they are not very close to exhaust heat, or in the path of debris from the road. Be sure that the pump is mounted at the same level or below the reservoir and that the reservoir is not located higher than the nozzle. If the reservoir must be located higher than the nozzle, a solenoid upgrade (part number 40060) is required to prevent gravity feed.
• Trunk mounting: This is fine, but again, the pump needs to be close to the reservoir and gravity fed. Lengths of 20-25 ft of tubing to the nozzle are fine. We always recommend a #40060 solenoid for rear-reservoir mounting, including use of the 2.5 gallon reservoir (part number 40014).

16. Is it better to inject the water/methanol solution before or after the Turbo? Where is the best place for a few specific vehicles?

There has been more discussion recently (especially on the internet) advocating pre-turbo injection. Most of the debate centers around increased atomization. You can probably get away with this in the short run if you inject a small quantity of finely atomized fluid (less than 10micron droplet) with a very low injection duty cycle. Also if you don’t care about turbo longevity (like some race applications where the turbo is replaced frequently) or you have a system that doesn’t atomize correctly and need the turbulence to help (low injection pressure and nozzles that aren’t designed to atomize correctly). In diesels, especially where injection quantities are large in relation to fuel and where there is benefit to injecting at low/mid engine load states on up, it becomes a question of when compressor wheel damage becomes too severe as pre-turbo injection has been proven to cause compressor wheel erosion. The amount of erosion depends on the quantity injected, the size of the droplet injected, the speed of the compressor wheel, and the injection duty cycle (what % of total engine operation is water-methanol injected). Also, the argument of reduction in compressor work per unit flow and the increase in mass flow rate doesn’t hold water in a properly sized modern non-wastegated turbo.



17. Where can I mount the nozzle?

Pre- or Post- throttle body/carburetor?

• Performance: It makes almost no difference. Before or after the throttle plate(s) won’t change the effectiveness of the fluid. A given amount of fluid will absorb a given amount of heat, whether it is done more before or after the throttle plate really doesn’t matter.
• Installation: It is usually easier to inject pre-throttle body in the intake tube. Easy access, no solenoid required (unless rear-mounting a reservoir). On a carburetor, it can actually be easier to use the #40050 carb spacer plate and a #40060 solenoid for a bolt-in installation. These components are included in our RT and MC series systems.
• In a blow-through carburetor setup with an air-box enclosure around the entire carburetor, injecting after the carburetor is preferable.

18.Pre- or Post- Supercharger/Turbocharger?
• Centrifugal/Turbo: (Procharger, Vortech, Paxton, Powerdyne, Rotrex, etc.) Never mount an injector nozzle before a centrifugal supercharger or turbocharger compressor. Sending fluid through the compressor wheel that spins anywhere from 50,000rpm to 250,000rpm can erode the leading edges of the fine aluminum. Studies performed by SAAB, concluded that pre-turbo injection will over time cause cavitation on the turbo wheel leading edges.
• Positive Displacement Supercharger: Roots style (B&M, Eaton, Magnuson, etc.) or twin screw (Lysholm, Kenne Bell, Whipple, etc.) Mounting the nozzle before this style of blower is perfectly safe and actually provides some additional benefits. The small amount of water-methanol fluid isn’t harmful to any rotor seals or surfaces or coatings, and it helps to seal the clearances and condense the air some more, resulting in a more efficient output. Additionally, it keeps the rotors and housing MUCH cooler, which reduces heat transfer to the rest of the intake and air charge.

 

I've had the system on for a week driven 800 miles and driving in 100 plus degree heat, I also see
the advantages of not having a heat soaked supercharger from this kit anymore.
Now that I've got this system installed, (I was on the fence before) I just don't know why there aren't
a lot more people out there that have superchargers with this system. When I was on the fence
I could only find a hand full of people that had a system installed for the TRD supercharger, more
for the turbo people. It's an inexpensive setup, 475.00, for a progressive kit, and has a ton of benefits.
No need for a intercooler, this kit addresses that.
A set of headers and a cat back system would cost
you more and you would get a marginal return.
For those of you with ping issues with your supercharger or those that want a smaller pulley
I totally recommend this kit to eliminate the ping and fuel issues without added and piggy back system or 7th injection kit or fuel pump upgrade. Of course my setup is at 5500 feet so sea level
would be different I think, maybe not? If you had a piggyback system then you could play with the timing and get even more power also.
Super clean system all installed, highly recommended over the 7th injection system and very inexpensive and easy to install with more benefits.

 

I am interested in this for my 2nd gen so some answers would be helpful.

What size injector are you using?
What are your start and stop psi' s?

Thanks!

 

Stock injectors, 2004 motor, the methonal will raise your octane up to 110-115 if you use 50/50 mix.
You can set the spray progressive kit by the rpms or by the boost, each engine will be a little different depending on what's needed and what size nozzle and what your runnnig, mine I'm running a 2" pulley and without the methanol I would not be able to use that pulley. I get an extra pound or 2 out of the smaller pulley. Each boost pound adds 10 degrees of heat, 10 pounds adds 100 extra degrees, the methanol kits can lower supercharger temps by 100 degrees, my AFR gets out of sync at 5 pounds, so that's when it's starts to spray up to the limit of 10 pounds keeping my AFR PERFECT. Each extra boost for me is about 15 horses. So 2 pounds is about 30 more horses.
If your not adding a lot of boost and your AFR is ok, then no need for the methanol kit, unless you need
to cool the supercharger down,
