here's some info on the summer. I emailed Richard and he has them in stock. I'm still waiting on his response about my idea of using the summer as a stand alone unit to get the 0-5V summed signal into my collingmist kit vari-cool controller.

 

This sounds like the winner for those using stock ECUs and re-chips.

I know most of the discussion has been around making big power, but some of us are absolutely keen on getting AI in their cars now.

For me, it's an awesome system. Once you've decided on the ratio of water to inject and the fuel injector duty cycle it will start to inject at, it's pretty much fit and forget.
I can see the advantages of a mappable system but, for me, it's a step too far. The Summer provides the ability to inject a set ratio of water/methanol to fuel. As the fuel requirements go up, so the AI quantities rise in proportion to it. For me, that's one less thing to worry about when mapping.
I have to echo too the previous comments on Aquamist's customer support. In my experience it's unrivalled in this (or any other) industry.

"should I get a 4 bar map sensor for my setup or will I be able to get reference from the built in 48 psi FJO map sensor?"

the FJO 4 bar MAP sensor is completely internal to the module and, as such, there is no way to tap into a signal wire.

FJO UPDATE

FJO has not as yet shipped to Alamo Motorsports. they are finalizing the boost control today, should get supplier prices mid week so they can finalize pricing. they are including a low level LED and have uprated the inflow tubing. they expect to ship within a matter of days.

i had a very interesting tech conversion w them. they spent a year developing their solenoid and it was all about atomisation. their concept is that water needs to be injected as finely as possible. this encourages atomisation which actually encourages significantly lower IAT (intake air temperature)... conventional wisdom is water cools mainly in the combustion chamber. FJO says they are getting alot of cooling in the runners due to their less than 60 micron spray.

most other agricultural nozzles or spray gun nozzles are designed for an 18 inch target (!) or a wide spray pattern when the target is really only 1.5+ inches.

add some meth in (windshield washer solvent "bug-juice") and you have wicked atomisation. buy the 40 below stuff. 'probably hard to find in Miami.

does their system work? how about a street driven camaro w 2 turbos running 7.8 at 175 in the quarter on 91 PUMP GAS and their HD AI using BUG JUICE!

AQUAMIST

a legitimate HD player w the summer module. let's hear from more users.

DUAL FUEL CELL

a sticky wicket at the moment.

i rough measured the available FD space. the area is about 24 wide behind the subframe and opens up to 34 inches at the rear of the fuel tank. the longitudinal dimension is about 20 inches. total avail height, from the bottom of the tank to the top of the cargo floor is 13 inches. that's what we have to work with. and. yes, there's an inch or two of additional wiggle. (move the muffler guard etc).

ATL will entertain a custom built to spec setup for alcohol and pump for around $3000. uh, count me out.

RJS makes plastic fuel cells that are not SCCA approved. they also make metal containers for the cells. make no mistake about it... these are not "fuel cell" like i used during my racing days. "fuel cells can be driven over by a tank." i wouldn't do it w the RJS items.

there are a couple of RJS cells that might work. they make a 15 and 22 gallon cell size. they also make an 8 and 5 gallon size for alcohol. around 140 a piece plus another 100 for a metal container.

they really don't quite fit in our space.

so maybe someone out there would like to step up and fab something... a custom side by side tank... 20 gallons of pump, 8 gallons of alcohol.

i have my $500 check ready.

any ideas out there?

Another member on here suggested this:

Why not partition off about 4 gallons of the stock FD fuel tank and run that as your meth reserve and then you still have 16 gallons left for primary fuel?

 

Because the FD is a glutton for fuel .

I went through the development of the AQ Summer with Richard on my car. I think I was one one of, if not the, first person to have it working on an FD. It was quite a process.

I will echo efiniste... The summer allows you to set a ratio of W/A to your fuel map and forget about it. It allows you the ability to just tune one map to tune in both systems. So I set water at 17% of fuel, dial in the summer to my injectors, tune the fuel map and bam! Works great. The AQ flow guage tells me that the system is working and flowing correctly and when the flow drops too low (clogged fliter, busted line pre flow sensor) it cuts back to wastegate only pressure...ie turns off your boost controllor solenoid. If the flow goes too high above range (ie. cracked hose after the flow sensor or other similar leak) it does the same. This is a pretty good fail safe in my opinion. The gauge, with the summer, and the fail safe make it a high quality system. Right up there with the best on the market. I am sure Richard has made some improvements to it since I got out of the game almost a year ago now.

The gauge also has a level sensor, so that if your tank runs down to empty the fail safe trips as well.

Once it was tuned in and working as it was designed (this took a lot of work on the summer, and flow sensor) it was a rock solid system. I went through a couple of versions of the summer and the plastic that the flow sensor was originally made of wasn't up to the FD engine bay heat so Richard had another one made out of delrin that held up. He said a metal one was in the works. The summer was tough because of the way the FD injectors are staged...but Richard figured this out too with a little feedback from myself and others.

The system as sold today would be rock solid from the onset. I wouldn't hesitate to recommend AQ to anyone.

Sorry for the bump, just wanted to say thanks. This is probably the most easily understandable informative post/thread on any forum I have read. Big shout to OP for the information provided in his posts in this and the other linked threads.
