I have been looking at mist nozzles. Seems you would need a heftier water pump.
The low octane petrol in a high compression engine can ignite like diesel before the spark plug gives its spark. The water injection cools the vapor and prevents premature ignition. As you remember these systems were popular when unleaded low octane fuel became prevalent. I used to take my MGB to the airport to get real petrol.

The professional manufactured systems inject post turbo and require a higher pressure pump to overcome boost pressure as well as spray a finally atomized mist. Water spray pre-turbo will eventually erode the turbine vanes. But that's tens of thousands of miles down the road, and the water actually cools the turbo bearing making the bearing last longer which is the weak spot on the cheap China turbos. Free turbo the lower pressure pump with large nozzle shooting a stream of water puts out enough water. It gets atomized by the turbo even though it's not a fine mist. It actually puts out too much water for a continuous flow. You have to push and hold for a couple seconds let off and then push again about 4 seconds later.

After I tested some more in warmer weather on the interstate I'll figure out how to move forward to something more automated. Now it's just push the button to make it squirt when the temperature goes up too much.
 
Hello,

Is it possible to use a water-methanol mix?

Just curious.





Juan
 
Yes. Some people use windscreen washer fluid which has water and methanol. Methanol has about half the specific heat capacity of water so it cools less but is combustible.

Yes. That actually works better, but you of course have to pay for it. The proper window washer fluid is about 30% methanol and works well. I bought some yesterday and have tried it. Not enough to give a good report. Initial results is that It cools a little quicker/better than straight water..................Alot of the people who run water injection systems will increase their fueling so that their vehicles make more power all around and then on full power runs the water/methanol injection kicks stopping the EGT's from spiking too high. I have not increased fueling, and my goal is merely to be able to run 70mph on the interstate without spiking the EGT's every time there's a small hill..............Please keep in mind I am experimenting/making do with something very cheap and simple that others have spent alot of time and money into a sophisticated high tech plug and play device... Intercooler integration into a 70 series that never had one is rather difficult. Water injection may prove to be a simple viable alternative to the intercooler in my BJ73.

Interesting that the methanol mix seems to cool better. Maybe the surface area of droplets and amount of time to travel from injection site to combustion chamber work better with methanol.
 
I have been looking at water/meth injection as well. There just isn't a lot of room on the 70 series, especially the 13BT to run an intercooler.

I already have the Auber gauge so hooking up a trigger for meth spray at a certain EGT shouldn't be too hard.
 
Cooled off enough to dry the roads (that is to freeze the water 😉) so took her out for a nice drive for the first time this winter.

You can fit a 4" air to water type if you put a 1" spacer between the hood and hinges, but you will loose 3lb of boost because it's restrictive.

I ran a front mount intercooler on the BJ70 converted with a 13BT, but didn’t have a/c.
 
Windshield washer fluid has dye and soap in it. I run 50/50 methanol/distilled water in my supercharged 1FZ. I'm not a fan of the impurities associated with tap water and/or washer fluid. I inject pre-blower. When I had my supercharger rebuilt a couple years ago the shop owner said it was the cleanest unit he'd ever taken apart. The blower had 113,000 miles on it at that time.
 
I removed the left fender well. Hoping to gain working room to get a compressor where the headlight squirt bottle was.

Yeah, not sure I"m going to use hood spacers or a water type at this point.

I've seen that build, pretty slick setup but I plan on keeping A/C. seems like it will be pretty tight.



 
OK, time for a new interior and a new electricity set up, 310Ah LiFePo4, 225 Watt Solar Set FSP 2 Ultra Foldable Solar Panel 12V + 15A MPPT Solar Charge Controller Smart Solar by Victron Energy

Think outside of the box ;) (all the cables you see on this pic are gone by now) :

Think inside of the box:

Get everything out again and start with the cables....:

You buy tons of stuff to save a few bucks... just got the news that the wood panels can be delivered soon... not so easy at the moment, here in Europe Wood is traded like pure GOLD....

Hast' im Lotto gewonnen?
Traumhafter Plan (und geile Darstellung). Lauter erstklassige Komponenten, aber sooooo teuer....
(Neid).

Won a fortune at the casino?
Great plan (and great illustration). All top notch components, but sooo f*** expensive.
(Envious me)
Schöne Grüße Best regards
Ralf

Hey Grüße in die alte Heimat, komm aus GL und hab in Leverkusen lange gearbeitet...

But to the points you mentioned, havent won the Lottery (yet), and I just want to be (ZombiApocalypse-)ready and to live and work in there and for the work I need some power, that is based on a self build LiFePo4 310Ah, if you want to buy that in a shop you pay something like 400% as if you order it in China yourself (but the thing is TIMING, at the moment no chance). I bought most of the stuff b4 the TOTAL SUPPLY CHAIN DISASTER)... The thing is if you build everything by yourself it is not soooo expensive. If you ask a shop to install all this forget it... but its a lot of work... and a lot of planning... And it will take some time to finish it... spend hours in the basement only to put tha aluminium parts together and we are not halfway there.... you got to see it as a hobby, other watch TV in the evenning, we go and play with cables or aluminium (I hate the english way to spell or say it right Alu...) ;) ;) ;)
 
Got the Red Rocket 2 years ago today. Put roughly 75,000 kilometers on it since then, not the easiest to daily drive a BJ75 put totally worth it to me. Will own this for a very long time, if not forever, unless I get offered an absurd amount of money. Can't wait to see what the future brings, hasn't really left me stranded yet which is pretty impressive for a 35-year-old car that hasn't been rebuilt/restored. So thankful for this car and the people I've met on mud and in person due to it, this is a pretty great community we have here and I wouldn't be able to keep the Red Rocket running without the help of thousands of internet cruiser heads. :cheers:

2 videos I made of my adventures this past summer traveling across the US in it with 5 of my buddies


 
Drove it to the beach for a surf and to pay homage to the crew of the S. A. AGULHAS II and Endurance22 on the epic discovery of the HMS Endurance. Without a stupid amount of time on Research Ships and a fair bit of time in the Southern Ocean, and on the ice I would not be able to have a 70 series. What a day for ocean science and exploration.

WOW
 
Looked over the inner wheel well panel.
Someone had used some body filler on it in the past.
Traditional rust holes.

Hard to say what to do about minor rot on a good functional vehicle. It's rather wastefull to tear into it all and cut and weld over minor perforation. Sometimes those holes are good in that they let the water drain instead of letting mud and water collect in between panels and seams. 2 years past a rust treated and undercoated, last year I repaired some old bubbling bondo. This year I have new bubbling a few inches from my old repairs. I'm considering rust converter followed with undercoat and spray foam to fill the perforated cavities.....Wish you could buy sheet metal "skins" to go over perforated bodywork. Kind of like the diamond plate aluminum panels you can buy for the 40 series, but not diamond plate. just cut/shaped to fit sheet metal skins you could attach and keep your vehicle looking good from 30 ft away and then one day in the long future when your original panel is sufficiently rotted you could buy new or cut weld high dollar restore................I live on a dirt road now my fender well seams continually collect and hold moist earth. Perhaps I could get some epoxy marine hull fairing compound and fill smooth all these seams with a more highly adhesive material in a way that dirt won't settle/stick there in contact with steel?
