My results where very similar to TTs. 563 awhp on a mustang dyno. Torque was over 600.

K24/18gs, 5 bar FPR, 72 lb injectors, EPL tune. Euro pipe s2 quiet. 93 octane. Running 1.3 bar at about 80 degrees. That's it for those numbers.

Regarding using the windshield washer tank for dual purpose, most WW fluid in the northeast is 20-30% methanol rest water, which is fine in a pinch, but when I am thrashing the car all day long at the track, I like 50/50 methanol and a couple of gallons of 100 octane, both more for safety than power.

 

When we tuned my car, I was on 93oct pump, spraying 100% VP M1 methanol. I had 18g's, 58lb injectors, FVD exhaust, Aquamist kit and STOCK EVERYTHING ELSE. Methanol will give you about the same results as bigger IC's (IAT wise), but without the benefit of octane. Meth WITH bigger IC's is certainly a plus.

This IS an option, but I didn't find it an attractive one myself. The float level switch is very difficult to install in the factory washer tank, without removing the fender. It is also much smaller than an aftermarket bottle, thus limiting the quantity of meth you can carry.

 

I installed the aquamist system. at the same time I also installed Alpha 28s suction piping and IPD plenum. EPL is still in the process of tuning it all in for me. I don't know what the total WHP is.
I have done water injection as a band aid protection in the past with other cars. I kept the timing flat above 20 PSI and found with water injection 20 PSI was about all 93 octane could handle. with just turning on the water injection. I could then run 23 PSI with little to no knock and very safe EGTs.
This install in my 911 TT is the first time I will take full advantage of the methanol as EPL will dial the timing and boost tune in with the water injection on all the time.

I don't think anyone should worry about sloshing in the tank or suddenly running out. If you set the system and your boost up correctly, Aquamist has three levels of failsafe in their system.
first you dial your boost wastegates to a safe level. like .8 Bar or 1 bar.
then use your ECU or boost controller to raise the boost to whatever you want to run with the Meth. aquamist uses a relay to shut off your ecu or boost controllers ability to raise the boost above the wastegate stock setting. (which your ECU does by pulsing a relay real fast to relieve some of the actual boost from the wastegate vacuum line creating a lower boost signal to the relay thereby causing the wastegate to raise the boost)

The aquamist system has a low level float in the tank. mount this 2 inches above the siphon tube feeding your pump. If this float triggers low level the system goes into fail safe and cuts your boost back to whatever your wastegate is set at (like 1.0 bar) no extra boost control from your ECU or boost controller will take place.

As a second failsafe measure if you should have a blown line or a Kink or a clog... the aquamist systems have a flow sensor right before the misting nozzles. This sensor can tell if the water is not flowing and then cut the boost. additionally you can shut off the aquamist system right from a little push button on the face of the gauge.

As the third fail safe If the system is off for any reason or looses power blows a fues or anything else like that. you will not have high boost.

You see, the system has to have power, be on, and healthy for you to run the higher boost that your car is tuned to use the meth advantages for. Any problems and the car will run just fine on 93 octane all year long at lower boost. just make less power.

I find for normal spirited driving the 1.5 gallon tank EPL sells works well. I just fill it up every time I get a full tank of gas. It has never run out doing it that frequently and it's often got about 30% left.

I went with EPL for tuning my Tial A28s because Tony and I both felt Boost without Meth injection is pointless your only get 80% of the potential.

 

as mentioned above, I have a six quart and a one quart and track the car a lot. On the track it's pretty much WOT or full brakes all the time. I 30 minutes I will burn 5-6 gallons of gas and 3-4 quarts of meth/water.

Also, if anyone is interested, I have a 2.5 gallon tank with a custom made welded aluminum mounting bracket (mounts to the driver's side front trunk wall, that I'd sell.

 

What does EPL charge for the auquamist kit, installation, and tuning?

 

You got PM.

 

are you injecting by boost or by IDC ? i will have to set up my aquamist soon, i see IDC more refined way but harder. Are you injecting like 4psi-25% 14 psi -100% or so ?

 

I set my HFS-4 up by IDC it was not difficult.

 

Great! did you use the default mapping of hsf4 ? i bought hsf4 too with dual 1.2 injectors

Are you using the same map for pump/pump+meth and race gas+meth ?

 

I did not use the default Mapping I will have to check it was a year a go, I only run 93 oct and Meth no race gas and Dual 1.2 injectors, the car is just a tooling around on the weekends car for me

 

Several people have inquired about my tank installs and Tony posted a pic of my current tank setup 6+1. Here are a few more pictures of both the 2.5 gallon tank with custom bracket and the 6+1.

EPL did all the work, including hooking me up with a local tig welder who made the bracket. They did a great job as usual.

Both tanks attach to the car on the rails you can see in the pics on the drivers side trunk wall. The 2.5 gallon tank also attaches to a factory bolt on rear trunk wall (you can see the tab in the pictures).

Sorry, I don't have any pictures of the 2.5 mounted in the car.

I'm burning about the same, I had a guy look over with me refilling my tank yelling "That's cheating!" then came the million questions
