Results summary:
I got this kit in November of 2006 but never had the chance to install it until July of this year. I could never get it to hold HOM and tried a few different types of additives - ranging from various mixes of windshield washer fluid to 100% methanol.
I was using an M5 nozzle that was mounted to a 90* elbow inside the charge pipe so the nozzle was spraying with the airflow. I had to turn up the pump pressure to almost full as there was a fair amount of pulsation in the line and the nozzle was not spraying evenly. I mounted the pump and tank in my trunk and had to go to Home Depot to buy enough hose to reach the nozzle while I waited for Chance at Devilsown to send me some of the good stuff.
I got the hose from Chance a few days after I did the install, but decided to leave the home depot hose installed and see how it went. Needless to say, the hose didn't last long. It was rated at 200psi for corrosive materials, but I think the hot oil leaking out of the stock airbox killed the line.
I replaced the hose and decided to remove the 90* elbow from the charge pipe and just tap the nozzle the way Devilsown recommends. This time, I used the M7 nozzle chance had sent me with the kit. I had about 1/4 tank of water left from my testing so I just filled it up with 100% meth for about a 70/30 mix.
The car held HOM through all gears, however, with too much load, it kicks me out (2500 rpms in 3rd gear). There's really no point in going WOT with that kind of load, so it works for me.
What I did find is that my next tank of gas was not that great, and it was kicking me out, so I went to walmart and got a couple of cans of octane booster (15 points/can - 1.5 octane) and threw them into a full tank of gas. The car held HOM with no problems after that.
I am running pretty rich though which means the car is not making as much power as it could, so I'm starting to play with the boost. Right now, the car is set at about 26psi falling to about 20 at redline. I have a boost leak at the surge valve which needs to be fixed with an aftermarket BOV and block off plate. I think I should be able to hold a little more boost to redline with that fixed.
At 26psi, the afr's hit about 11.1:1 at about 4500 rpms and then dip deep down into the 10's all the way to redline.
Up until a few days ago, I thought I would have to go out and get a dual nozzle progressive kit to hold HOM, but I guess I got lucky and figured out the right combination.
It boils down to tuning at the end of the day and a little bit of luck.
Thanks Chance for a fantastic kit and even better support!!!!
