Meth/water injection?
 

I have decided to add a met/water injection system to my car only to be used on the track as a safety system. At this point I'm thinking I'm using the Aquamist system, does anyone know of a better system or have a reason why I shouldn't use Aquamist?

I used this one on my Sti. Worked great. Coolingmist CMGS PRO Water Methanol Injection Kit Import Image Racing

Aquamist is pretty much the best available, but there are other options out there that will work fine.

Are you forced induction or na? If na I wouldn't bother..

It has a Stillen supercharger on it.

If this is true thats what I will use, I want as much insurance as I can get! We are not going to tune for its extra power, just for cooling and safety. My car is a 7AT with 302 tq at the wheels so with the trans ratted for 300 I don't want more. Thanks for the help!

Aquamist is a good choice and is what I use. When I moved to Texas, I knew this was a must. The Aquamist held up well in 110F Texas heat. It also helped tremendously with keeping intake air temps down and boost levels consistent. In the winter I don't use it much and actually tend to turn it off.

Great! Thank you for your input! I probably wont run mine unless it's real hot or on the track. It's really to save the motor when I'm beating on it.

when i had my stillen i used stage 2 snowperformance
i did not get it tune for power but i also used it for the cooling effect
and when using it i could touch the intake manifold after a run before it the intake manifold was so hot i could cook an egg on it

i still have every thing wired up and think i may use it with my turbo kit

i had a single bung weild onto the intake just before the elbow
and in the cockpit i had a switch to turn the system on and off with an led indicator for when i was getting low on fluid

Did you see any change in oil or water temps with it?

I can't imagine it having a dramatic effect on anything but IATs.

Hmmm...I would have thought taking the heat out of the intake would effect all of them. Either way less heat is a good thing.

^^ definitely. Air is not very effective at heat transfer (especially when compared to water/coolant or oil) without some type of heat sink.

But wouldn't any heat taken out of the cylinders by the meth be heat that doesn't end up in the water or oil?

Maybe a bit, but I would thnk most of that heat leaves with the exhaust anyway. The Stillen kit seems to have an IAT issue, not coolant or oil. If you've got an issue with one of those, I'd address it with a radiator or oil cooler. Have the fans kick on earlier through Uprev. Meth/water is for IATs and knock resistance.

I don't think I have a heat problem but it hasn't been on the track since the supercharger was installed so I'm nervous about it. I have a oil cooler, lowered when the fan comes on and added a Carbon Creations vented hood already so hopefully that is enough to keep it cool!

That should be enough for oil and water, provided you've got the fans set to turn on early enough and you're running a 75/25 water/antifreeze mix. Meth/water should handle all your IAT and heatsoak issues. If it were my car I'd look into a larger heat exchanger and larger radiator as well. Anything you can do to keep the car cool will help.

I don't think I have the room for a larger radiator or heat exchanger, the nose of my car as a crap load of stuff in it. I'm actually running water and Water Wetter only since it never freezes here and my car will never be anywhere it does while I own it!

A CSF radiator fits just fine. Any size difference is on the engine bay side. And others have managed to squeeze a bigger heat exchanger in there.

The CSF radiator fits in the factory spot without much if any modifications, it is what I have.
Other upgrade is the fans, GTM has a pre-made kit that plugs in and goes. You can probably piece it together cheaper but will have to wire it all up.

I've got the fans on the list of "Items I'll buy from GTM once they get back in the business of actually sending parts out to people who send them money". :rofl2:

There's also a Nissan thermostat that opens ten degrees cooler than stock. I've got one on a shelf in the garage for the next time I'm in there where I can get to it.

Same, I am waiting for summer to finish my data logging with my hood and see what difference it made and then throw in fans on top.
Should bug a few other companies to make a similar setup, fan shroud, fans, wiring, all in one & ready to go.

I'd even pay a little more for the same thing from a company who will take my money, process the order and ship me goods in a timely fashion.

Thank you both for the info on the radiator, I will have to look into that. I got on the list for GTM and even had a check ready to be mailed out but decided I didn't want to be part of that. I own a legal machine gun and was in a group by for new parts for it and lost some money so I'm just not very trusting of buying things before they are built. I would gladly pay more for the confidence that I will get what I'm paying for.

On the topic of water/meth injection, what are some of the pros v cons using this system?
JWillis, you want to use it for track purposes only, how hard is it to set it up like that?

Where did you find this neat little fact on 300ft lbs?

Comes from my research and 7AT thread:

Where you get that from? whats the part number please?

If I'm remembering right, it's from the 2008 G37. Only the 2008 for some reason. It's at home, so the part number will be later.

Weird. what makes you so sure its not the same on all VHR motors?

Grassy-áss

Didn't know it was straight advertised.

The one at home is 170, OE 370z is 180 and OE G37 2009+ is 190. Not sure why there's a difference.

Never knew there are three thermostat for VHR engines from Nissan.

It doesn't make a whole lot of sense to me either, but they've done weirder **** in the past.

I am not going to tune for extra HP so it's not that hard to set up. I think they said 3-4 hrs to install. If you don't tune for it there really are no cons, the pros are a great reduction in heat. The system I'm ordering comes so you can turn it off.

This is the kit.

Howerton Engineering, LLC – Aquamist HFS-3 Injection System

not the same kit but this shows how it works.

How Water/Methanol Injection Works & How It Makes Horsepower in Gas Engines - YouTube

That is exactly where I got it.

I'm just going to run this stuff on the track so I don't have to mess with mixing the meth and water.

Snow Performance Boost Juice

Correct. 2008 G37. Part number is W0133-1725928

I picked mine up from partsgeek but I'm sure there are others

Here's one googled link:

Infiniti G37 Genuine W0133-1725928 at Auto Parts Network

G runs a 180 too except for 2008.

Yeah, I heard the number in 09 but never could find solid proof until I created that thread.
There are references around the web about it that say 300TQ and everything but that was the first real details.

Dreamer, if no one else has said it, I appreciate that your our FI historian here!
