Another potential problem is with varying water pressure , it has to be perfect 100% of the time otherwise if you have too much water in the cylinder you are basically "putting the fire out" too little and you could detonate.
I love the idea and theory behind the WI but its IMO a little finicky for proper everyday application.
Now methanol is a different story, it burns better and cooler than fuel, but it is very corrosive and needs a completely seperate injection system that would probably need replacing every 5-6 years due to extreme corrosion.

We had a group buy on these about a year ago from Snow Performance.

Did he tell you how his fail safe switch works? Did he say if it was just a pressure switch?

Well, apparaently snows diaphram pump was more consistent than others out there hance the WRC team choosing snow. They had the same concern and its comforting to know they went with snow.

The failsafe switch is a flowmeter impeller type with pressure also I think, Sound like the ****. As far as finiky, I think if you have closed loop knock and other failsafes you can minimize your risk. I have been wanting to experiment with it for a while anyway so here goes...

Thanks for the info I think I will email him to find out more on that.

With timing advance and being able to run about 2-3 more psi safely, 20% at the wheels is about right, if not a little conservative.

Maybe another group buy?? I am sure Matt would allow your purchase to be retroactive and give you the group buy price.

My buddy developed a system for a 930. They are working on a 951 system soon to be done. Check out their performance gains:

Nice system but.......$2,300???

B951S

Group buy would be cool.....chime in guys, I will be sure to document my progress for others in any event.

Claus Groth

I am still undecided about which system to purchase and am interested in a group buy. What was the discount the last time?

Kevin,
if somebody wants to be a real *** about it, your buddy could possibly have legal trouble.
He just copied info right from the aquamist literature, and it looks like he's just using aquamist's pump and creating his own overpriced system. Aquamist had to research all the numbers as far as heat removal ability.

As far as the basic concept is concerned, the same ramble just keeps getting repeated from one party to the next: very high heat absorbtion, increased VE, blah, blah, blah. Then everybody treats this over-generalized info as technical gospel, and some of it is not even correct.
For example: the blurb about water slowing down the burn rate like race gas.
Octane of the gasoline has nothing to do with how fast it burns, and secondly, if your charge in the combustion chamber burns slower you have less power potential.

B951S

Here, here TurboTommy, but let me ask you this...with some alcohol / methanol in the mix it I thought it burned more slowley thereby causing peak cylinder pressure to occur when the crank is rotated more thereby increasing torque...... Anyways, be that as it may, I'll slap it on and see how she blows.....

Why would you ever pay $2300???? Oh, I forgot it's for a Porsche.

There are kits all over the place for about $300 to $500.

If anyone wants to build there own...here's the link:

Cost: about $289 total Universal kit is at the bottom http://home.att.net/~alkycontrol/page1.htm

NZ951

I would be keen on the GB, but I want to see an installed one first, mounting areas etc, preferably with a link attached to it

Anyone got performance gains or other relevant data with this system on a 951?
