Lol, kind of like some of my posts, lol.

 

silvercoupe, that sounds like a great setup. I usually recommend nitrous to all my customers when asked for quick power, but when it's low boosted setup. water/methonal is definitly the way to go. We recently used a very similiar kit on a TDI golf for one of my customers. Went very well

goodluck with the KIT

the air from the turbo is so hot that the water never reaches the combustion chamber.... this is the whole point. The water/meth evaporates off of the sides of the ic piping and/or intake manifold.....
evaporation = cooling process = cooler air = more boost = more power
i just read the new d-sport yesterday and they slapped a meth/water injection kit on a car running no more than 13psi.... after tuning the car gained 34ft/lbs and 15whp. just imagine if the boost was at 20 when they started and the gains he could have experienced.

 

Believe me I understand the concept but again I'm not willing to tempt fate on this one. I've finally got a car with a decent power setup and I don't intent to even consider something that IF it should go wrong I'll end up with a hydrolocked engine and massive amounts of damage. Meth by itself I might be willing to try but not until I manage to get myself something like the Apexi NEO or something similar that can keep track of everything and use to tune properly. I'll play this one on the safe side. If anything I'd get a CO2 kit for the intercooler instead of putting something IN the airstream itself.

 

Sang the pump isn't on the entire time, it's on at whatever boost level you want it to start at. So if you have your boost set at 18psi, you can set the pressure relay switch to turn on at, say, 10psi and the pump shuts off as soon as you go below 10psi (or whatever you set the pressure relay to).
So, the pump is on ONLY when there's higher than cruising pressures. It doesn't go by RPMs, it goes by boost pressure.

Again, the pump isn't running the entire time. The water/meth is also in mist form not in a jet stream and that water is vaporized from the heat of the forced air. What you are saying is why it's not recommened to use low pressure pumps. High pressure pumps create a better misting property than lower pressured pumps.
Water serves as the air cooler and meth serves to raise the octane. In the end what you have in the cylinders are a more dense,cooler charge of air.
Also, it takes roughly a cup of water to seize the pistons. That's a cup of water all at once. The pump would have to be on with the motor off for a good minute or two before it fills a cup. It'll fill a cup when at boost really fast, but that's when you need it.
Here's air pushing through an intercooler with W/I.

That's not enough to lock the motor while at boost. It's not like driving through a puddle with a CAI or anything like that.
BTW, just about any liquid can hydrolock a motor when taken in large amounts. Also, these pumps aren't made to run full meth. There has been a case of pumps failing because of the highly corrosive stuff eating the pumps. Everywhere you look, the pumps state to use a 50/50 mix of water and meth and never full strength meth.
I'm not trying to get you to buy one bro, I just want you to understand that when it's setup correctly, you won't hydrolock your motor. It really is hard to mess that up unless you just ignore what others before us have done...or didn't do, lol.
There's another benefit to w/i and that is you'll be able to run half the size of an intercooler with w/i because they both serve the purpose of limiting/eliminating knock.

 

Oh I understand like I said. It may take a catastrophic failure to actually cause problems but I don't intend to tempt fate once I get the car back up and running. Anyone that wants to, more power to ya. I'll be looking into a CO2 intercooler spray myself. Something external to the engine but also has the same tempt reducing effect.

 

Lol, I understand Sang....one step at a time right?

 

Exactly. Let me get the engine running and the 3" exhaust installed. then I will be saving for a turbo upgrade and the Apexi NEO (Prolly get the NEO first actually) THEN I'll consider the injection kit.
