Indeed, i wish i could read that wack schematic they posted? What are those two different sized rings about? A multi nozzle array?...

Without trying to be a critic, i await to see what closed loop system they implement for when the espresso machine water pump, even mounted in a metal box, dies from having to pump a constantly varying water pressure loads for a few years.

On a second look at the schematic, it looks like its a setup from a jet turbine, hence the "engine water pump" at the bottom left, and the duel staggered ring shaped nozzle array.

Those pressure regulators and the surge chamber sounds pretty trick. As for triggering, i would think the regulators would take care of that. Awaiting part 2 !

AutoSpeed Water Injection System Part 2

Interesting. I do like their seemingly comprehensive testing procedures and logic.

Though it looks like they are going to position the nozzle before the air filter, claiming it'll will provide "proportional amounts of water : air"

I'm not so sure about this. The key IMO, is being able to tell the existing ECU (in AS.com's example, an OEM ECU) that the detonation suppressing system is working and to take advantage of this with more ignition, less fuel etc.

For the system to be really worth it, it should allow such aggressive fuel/ign that if the system ever failed to turn on, the motor would suffer serious det damage... this is all means, the control of water : air must be EXTREMELY tightly controlled, not "roughly proportional"

my 2 cents

Not entirely, would be pretty impressive if they run that coffee machine pump for a good few years without issue.

Also, the IC intercool spray pulled like 25% more heat from the intake charge, then WI! lol.

Proper WI in the US is pretty big. Its essentially another whole fuel system, rail, injectors, reg etc. They add a water soluble oil to the water to allow Petroleum hardware to work and not rust. They run real 40% water : fuel ratios, not the 65 ml/minute AS.com are trying.

      Seat of the pants assessment of the new intake: The car is way less "doughy" when hitting the loud pedal, especially off idle when stopped or in traffic, I did use a cheapo lazer thermal thingo to measure the temp around where the pod filter got its air, it was between 55 - 60°C, in saying this the car was shut off and not moving, so the OEM intake pipe was not supplying any fresh air to where the pod was when the car was at least moving A weird bonus was induction noise on the throttle in the cabin increased a bit,  I was worried that I was actually going to lose some of that induction noise I love so much, outside though, when I got the daughter to do a WOT drive by pass for me, the induction noise has increased alot when on the throttle, not quite ITB doort, but well up there I'm extremely happy with the results and have been exploring the country roads in the region  As for house mods: 1.New front fence is up and is awesome, it really upgraded how the joint looks from the street, and the added security is nice 2. Electricians have replace some interior lights, and with more lighting in the garage, a few new motion detecting lights out the front above the garage, front room, and at the front door, which I have already found heaps helpful coming and going, also now has fancy pants CCTV all round the house The only hold point for power though is the solar and batteries due to supply issues, although this will happen over the next few weeks 3. I have done a heap of landscaping out the front and I'm almost ready to do a new small retaining wall with some nice blocks to replace the brick and cemented in rocks around the raised garden beds cemented in river stone "was the fashion at the time" the house was built. I currently have a pallet of retaining wall blocks and 2 bulka bags of 20mm blue metal to replace the wood chip that is in the raised garden beds around the house 4. I now have 3 big raised garden beds for out the back to grow some vegetables, about 70cm high, 200cm long and 100cm wide 5. My 2 compost bins are already pretty full with brown, green and kitchen waste from the landscaping I'vedone so far, but they will probably take a few months to break down, so anything else that gets chopped, trimmed, and kitchen waste will just start filling the base of the raised garden beds to about 30cm before I start throwing 40cm of good compost, and stuff, for the vegetables to grow in, I'll need a few ton of compost and soil, but the local supplier can sent me bulka bags of the stuff Basically the logs, wood chips and a few strategically placed rocks for drainage, will give the beds some good organic materials down low to break down over time, and they will hold moisture during the warmer months to save the water in my big arse water tank if we don't get alot of rain So, all in all, the car and house mods are going well, and I'm really enjoying being retired, I sleep in too 0700 and slowly plod around inside until I feel like actually doing anything, and only work in the yard for as long as want, which has actually been alot over the last few weeks,  although when you look at it, it seems that not a huge amount of work has been done,  until I look at the before I started the work pics Happy days and good times indeed

      hahaha yeah. Plan is to get side skirts and probably just rear pods. But going to do them one-by-one. I've got a set that I really like from RHDJapen, but that one isn't shipped to AU. So need to find someone who can get it for me

      Here's an idea, answer the questions I asked you as they are trying to work out WHY the LSD will be binding up in a straight line.

      You haven't driven many modern cars then have you? Most of them have sfa steering feel with their stupid electric bullshit steering systems.
