Yes it is the MAF kit.
I had to order the optional solenoid kit because I will be injecting after the throttle body to avoid spraying the MAF sensor.

This kit varies the flow based on intake flow and boost level.

I've been eyeing that same kit as a future mod after I get my tranny and cam swap done, and was going to set it up the same way you seem to be doing. I guess I won't have to wait until then to see what kind of gains there are from it.

There won't be any GAINS so to speak from the WI. Some, but not as most people think. The gains come in being able to drop another pulley size without KR.

I agree with Bill.
Except there is an additional gain from the cooler intake charge. The system is proven to be able to reduce intake temps from 50-70F. Using the rule of thumb 1% hp gain for every 10F drop in intake temp ==> 15-20 hp.
So with the pulley, 120 octane methanol, and cooler charge ==> 40 hp

Sorry, I should have worded that better. I meant gains as in how much it would affect temperature compared to an intercooler. Methanol is 120 octane. I thought is was 102 but I may have switched the numbers around.

I'm sure you have Shadd watching this topic with much attention. Him and I were talking about this for his car when I was at his place in January.

Thanks for the reminder. I'm supposed to spec a system for him.

Paul, you're running no richer than a 50/50 mix, right?

The colder charge for those that are following this equates to more air. Colder air is denser than hot air. In effect, why a hot air ballon rises. It'* lighter than the colder air around it.

This is why your car runs best on a cool foggy morning.

Yes a 50/50 mix is ideal.

It'* the golden 1% increase in hp for every 10*F drop in intake charge temp. Estimate a conservative 50*F drop in temp for 5% hp or 15 hp (based on a 300 hp engine).
That'* 35 additional hp if you add a smaller pulley and the effects of methanol on octane rating.

A short stack intercooler would give you about 85*F temp drop and a full thickness intercooler can cool down 140*F, good for 8-14% hp increase or 25-45 hp based on 300 hp engine plus additional if you pulley down also.

So an intercooler is better but the Water/Meth Injection will gain almost as much potentially.

Mounted the bottle. It fits perfectly inside the cool box.

The real challenge will be mounting the pump. It is a heavy unit weighing in at 4.0 lbs. It is made by Sureflo. It has four rubber isolation mounts.
I am planning to mount it inside the fenderwell by attaching it to the transaxle frame rail next to the antilock control module. Designing a custom mount. Have to make sure it isolates the vibration and keeps it secure on top of the frame member.
It would be a real challenge finding room for an intercooler pump.

I bought the optional fluid level indicator, it is a simple light that comes on when the level gets to 1/4 tank.
The tank holds about 6 minutes of spray time based on max output. This is a variable unit, so it should last double that. Good for plenty of 1/4 mi runs.

I also bought the optional pressure gauge kit, it is simply a tee and connector. Searching the parts bin for a 300 psi gauge. Output pressure of the pump is adjustable using a 2 mm allen key. Mine will run at 160 psi.
The 15 amp circuit off the horn is what I will use to power it with an on/off switch. The kit comes with a system on light also.

Now the next question is where to mount the gauge. I think I'll leave it in the cool box with the fuel pressure gauge for now.

The MAF controller fits perfectly on top of the speed control module. I just have to find some 3 mm x 45 mm long bolts to replace the original 3mm x 15mm bolts. It will sandwich on top.

How much distance is safe to have the solenoid shut off valve from the injection nozzle.
I'd like to place it in the cool box but it would leave about 2-3 feet of line. I don't think it would syphon out beause it is not vented. What do you guys think?Bill?
