I'm getting ready to order mine, but before I do that I wanted to hear how you guys are running it. Any advice is appreciated. Particularly mounting location, what mixture/chemical are you using, what psi are you engaging the system, did you up boost/timing/or both after installing this system, are you satisfied with the SMC product, what size container did you buy(I'm thinking of the 2 gallon for a trunk mount)?
Thanks guys,
Mike

I've got it . . . running the 1 gal container in the trunk area . . . I'm pretty satisfied so far! I've dynoed 575/624 on bone-stock motor and 91 octane with a 50/50 water/alky mix. Next time I'm going to try 100% alky, I think it will work better from everything I have read.

Chris, did not actually install it myself, I had a laundry list of things to do ( like subframe connectors ) and paid the guy to do it all at once. It doesn't look difficult at all, no more than running a nitrous kit. It is activated by boost, can be variably set. Mine comes on right around 3-4psi, plus it has a master switch.

I have it. A one gallon mounted in the area between the rad support and the fascia (where the bumper support used to be). The thing is excellent! I used a "Mad Professor Eric Connelly" mixture with 50/50 Alky and water and around 4 ounces of acetone. I am on a bone stock 00 long block with only 918 springs. I run 10 pounds of boost on MI 93 octane. Absolutely zero KR, and it runs like mad. It starts up at 6-7 pounds and is at around 50% pump speed (lots of room for my LPE intake and cam and maybe 1 or 2 more pounds of boost)
If you mount the bottle in the engine compartment, it's child's play to install. If it's in the trunk, then two things:
1) Treat the line as fuel and run it OUTSIDE your passenger compartment.
2) Turn the start boost WAY down. Raymer starts at 2 pounds. It takes a while to pressurize all that line.
It's worth every dime.

Let me know if you have pics of your trunk mount.

Mine is not stealthy . . . as soon as you open the hatch you can see it
Preferrable spot would be where I had my NX bottle, but I haven't checked to see how well it would fit. If I can think I will snap some pics when I get home. Again, not where I would REALLY like to have it, but I'll probably move it eventually.

An Alky system adds absolutely ZERO hp. It only supports more timing, boost, compression, what have you. The objective, at least in my case, is to suppress detonation (reason for the H2O), and add a smidge of temperature reducing, octane enhancing Methyl Alcohol. Once that's in place, dial up the timing and boost until you're on the edge of detonating and back it down a notch or two (depending on how brave you are) or turn the Alky/Water up a notch or two more (if you're even more brave.) I submit that you'll stretch the head bolts, collapse the weak pistons, or break the rods before you detonate due to lack of Alky/Water... On a stock engine at least.
OBTW, a gollon lasted most of the season of being in the boost.

Chris, I had been asking many of the same questions . . . SJH pointed me to some NASA studies . . . it seems that 100% alky is the best. Water definitely prevents detonation, but it steals power at the same time. I dynoed on a 50/50, next time ( after valvespring install ) I will be dynoing with only alky.

From what I have read and understood, the extra octane in the denatured is what is stopping detonation . . . I have no real world tests to show you, but this is what I have read. Check out this link, tons of good info!

I'm not really sure how long it last because I try to refill it every other time I drive the car. The most I have run it without filling it up was at the track when I made about 10 passes 1/4 mile. And a couple more times on the way home. I think I used a third of the tank. Also, I have mine turn on as soon as I hit boost.
