We'll be putting together a package and adding it to our website.



Injecting just water will only improve knock resistance. The methanol will lower intake air temperatures more than just water alone in addition to having a higher knock resistance than gasoline. Jordo and I had a good discussion in a different thread that went into more detail.

If you are doing water/methanol or just straight water, you MUST use DISTILLED water! Any dissolved solids will clog the injectors over time! Think about how often you have to clean/replace the aerator screen in your faucets at home...especially in SoCal where we have nasty, hard water that is barely potable. You do not want that dissolved lime and crap in your motor do you?



Like Nix said, we Americans rate our fuel on the conservative side. Our 91 octane is comparable to your 95 octane and our 93 octane is comparable to your 98 octane.

As far as how it would impact the S/C kit, you would run a little richer on higher octane fuel as it would have less propensity to fully combust. Therefore, you would have a conservative tune for your conditions...nothing wrong with that.

You currently have a HFS-3 aqua mist on your website. is it the same?

Just to be clear, my understanding is that injecting water should improve knock resistance and lower IAT as well as allow you to (in theory at least) run a leaner AFR since you can replace fuel with water for cylinder cooling. Water has a significantly higher specific heat capacity than any sort of fuel which makes it phenomenal for cooling (as compared to say gas). I definitely understand that you need to run distilled water only, but like I said, that's available anywhere and it's cheap. Meth mixes aren't.

Another consideration is the fact that meth is a fuel so *I believe* you have to tune the fueling more than with just water. With multiple maps this may not really be an issue, but I strongly prefer simplicity.

I do realize that you don't have the added power potential when you run just water and no meth, but my goal with a water injection system would be safety margin, not additional WHP. But that's just me.

In any event, congrats on the awesome build!

Yes, injecting water does lower IAT, but meth does it better. True, water has a high heat capacity, but methanol evaporates faster and it's the change of state from a liquid to a gas that absorbs lots of heat (methanol boils at a lower temperature than water).

You don't necessarily *have* to tune for it, but it is beneficial to do so. Anyway, water injection is perfectly fine for what you want.

So, when are you going to be doing this build? :tup:

No arguments with that! Well, I am picking my car up on the 27th. So, after a full break-in and a little financial recovery from the down payment, I will be up there to see you guys. I decided to do the brakes on my car before I even picked it up so there went some of my mod money, haha.

Is water or water/meth injection recommended if one is using 98 RON fuel or is this just an optional extra?

So you made 466 rwhp @ 11 lbs boost. That seems kind of low. Is your car a 7 AT ?
i thought the UAM car made 507 rwhp. ?

interesting, i wonder if it's because of 91 oct. My HR did 450whp at 10psi, so you are not the only one with lower output numbers. Altho that meth injection system is seriously impressive, did not know it can bump up almost 40whp that easily
