I was holding HOM reliably with the varicool setup as it shipped. I upgraded to the AGP WG and I couldnt hold HOM anymore. Boost came on so fast that the Dual M5's (yes thats like an M10) I was running would bog really bad at partial throttle.
I broke out the PC and did several runs experimenting with the curve, onset spray, and added the 2d option using the throttle position sensor. A little tweaking to the curve, setting the spray to come on after 40% throttle, combined with the start spray and full spray I have officially killed all knock and am holding HOM in the 1/4 reliably again This is using 91 octane gas and an 80% meth mixture.
David has answered all my e-mails very fast and all of his suggested changes to my setup where spot on! I see allot of questions "can I hold HOM on S3 with WI) I can tell you that for sure it is possible with coolingmist's trunk-mount varicool setup and a little tuning !

Brian,
I am so happy for you that you have your problem solved. We spent along time to engineer the Vari-Cool to do things never seen before in a progressive controller and its nice to see that you were able to take advantage of the engineering that we did to make this type of thing possible. Our competitors will bash us left and right telling us that its no better than a regular progressive controller, but we like to let our customers such as you speak for us with actual results. What you did with our controller could not be duplicated with another progressive controller on the market.
I am very glad to hear that our system works for you.

sweet.. tell me what i need to buy. what kit, nozzles, etc.

coolingmist - how much for the setup he is running?
Sorry guys the last few days have been busy and I haven’t had the chance to post. Here is how I have it setup.
I have a tank mounted in the rear corner of the trunk. The pump is mounted below the tank under my spare tire. The water line goes under the car following the fuel lines.
Now I don’t know if this will matter for holding HOM or not but for my nozzle location, rather than using a single M10, I did something a little different. I saw lots of debate on where to put the nozzle for best knock suppression and for best cooling so I decided to go with the best of both worlds. I had Justin at JMB weld two bungs in my hard pipe. One as close to the IC as possible and one as close to the TB as possible. I then put an M5 in each bung and called it a day. The coolingmist check valve is located right before the T fitting that splits to the two nozzles.
As for controller settings I have it set to start spraying at 5 psi and full spray at 17 psi but only above about 35% throttle. This way part throttle boost doesn’t trigger to spray and bog the engine. For slope, I am still playing with what feels best and will be hitting the dyno soon to see what gives the most power.
My meth mixture is HEET concentrate washer fluid which should be about 80% meth.
The all in one trunk mount kit should be able to duplicate this setup if you buy an extra nozzle and a T fitting..
Guys, we are working with Brian on this. We will be releasing the SRT-4 HOM kit shortly. It will be setup exactly like his with the same nozzles, but also we will set the programming up to run in special control mode so it runs only above 35% throttle and then under boost.
It will be setup with the 2 nozzles, tee, etc.
Pricing depends on options such as tank and hose style, but will start in the $500 range retail off the website. If we have enough interest in this I can do a group buy , with enough interest we can get the price pretty rediculous.
We need to do a few more things before we officially release the kit, but if interested in a group buy please post up here.
How did you acomplish the 'on at 35%' function?
Nice work by the way.
One of the things that seperates our progressive controller from others on the market are the software functions. Using our software you can run the system in "special control mode". This allows you to use multiple inputs. In Brians case he was having perfect flow at high boost, but too much at low boost. One solution would be to set it to come on at a certain throttle position. Since the TPS is a 0-5V, its simple to tell the unit what voltage to come on at and then create a map using boost as the progressive input.

coolingmist does it again!
This is using 91 octane gas and an 80% meth mixture.
