This just keeps on getting better and better!

Very nice car and that engine bay stays like new always!!!!

Yes it's amazing, what seemed like a limitation a year or two ago today is the new base to work from. It's one of those things though where you do need years to prove the concept like I am doing here (various technical challenges & base line calibrations aside) nothing much in the hardware is exceptionally "different" just very minor settings changes and applying all of my knowledge and experience means I now can have a 13B rotary car in compliant street trim that is faster than many peoples race specials!, all while keeping amazing durability for something that is making such prodigious horsepower

I remember reading in one of my text books from my engineering days on the development of BMW's 4cyl turbo F1 motors where Gordon Murray (Brabham/BMW designer at that time) basically said their whole program was in the firing line after a couple of years trying to go turbo, and in the end it was something so small and relatively stupid that either made it work or not (ended up being a simple calibration setting!)...... *Moral there* Lets not forget how miserably Ford Cosworth failed in attempting to make a 4cyl turbo to match BMW's at even half the power let alone 1300+bhp

I have my own little (by comparison) developments, and its all part of the challenge to develop something no one else can and do it on far less, its not the cubic dollars that makes the difference just a great concept (WATER INJECTION) applied well, and set up to achieve what its always shown through history to achieve, the best power, with minimum stress, and all on common parts (be they mechanical *engine* or chemical *fuel*)

Hope it inspires people to follow what Sir Harry Ricardo and other great engineers have bestowed generations ago

I was inspired when i stumbled upon this forum by chance,in fact i was researching a bit on water/meth injection.
Then midway i figured that you are not a trader over here but a real enthusiast...haha!

What you have done so far is truly amazing,hope you will carry on with the good work and keep us scotched to the screen with your achievements!

Will seek some tips later when i get into this.

Thanks very much, I am an enthusiast first and foremost. I have been doing this work for over 20 years now and will NEVER EVER STOP! I'll continue to do it for the next 30 or 40 years not sure if the internets or the world will be around that long though.

I have been using RICESP as the daily drive now *till my new tow car arrives!*, as well as weekend cruiser (just came back from a 200km 3+hours scenic lunch drive ) the car is flat out amazing in every respect, a true street car but with supercar destroying proven ability fast, efficient and reliable. can't wish for any more than that. Next few months will be a bit quiet due to work commitments and using car day to day, but will update anyway as quite a few people keep in touch and want to know how things are. Just on my drive now I saw two of my students, boys were gagging over the Mazda *they are only human!* it once again as I probably have been stating over and over is the ultimate real street car, jump in it drive it anywhere anytime anyplace and not go broke doing so or worry from fear where you can buy E85 or some such other garbage fuel lol..... The power of WATER INJECTION! you just cant beat it! no matter what you read on the internet forums lol

I have been reading about the nozzle type you are using, and was wondering if the nozzles could be used with a pump feeding the water side, and only boost feeding the air side?

I guess you could do that (I have never tried it). It would defeat the purpose of the system to be "simple" using an electric pump, + you would have to put in allot of work with PWM control of the valve to meter the water in (which is basically self regulating with boost pressure feeding the water). Hope that makes sense to you.

I was thinking about using my current kit, and using the new nozzles to reduce the micron size for the turbo's ingestion. Don't know how much it would help though.

Are the coils you use for motorbike applications?

Hey Grant,

Yes the CDI Coils are Dynatek 0.5ohm units. The CDI boxes are Dynatek ARC-2, everything else is bespoke manufactured to facilitate the use for coil on plug on the 13B. It's very expensive and hard to copy which is why most don't do it even after seeing my pioneering pictures and parts lists I put up

They have been faultless!
It's winter time here now and most mornings when I take the car out its -2 deg C or so...... daily driving it last few months to finish of durability trials on all system parts, its covered around another 3000km, colds starts are immaculate, runs on race plugs of normal heat range, and is just perfect really....... as good as any OEM out of the box set up, pretty amazing given it delivers well over 650bhp now!!!!!!!

Have been getting an amazing amount of mail on WI (daily!) and most refer straight back here for people to pick the system that is right for them and also to learn more about the best technology ever invented for the internal combustion engine. Was a dream of mine to share this knowledge one day and that day has well and truly arrived! I suppose you cant deny the power of water injection when you see the results of cars like this and others (across all fields!) that have run it since 1930

Water Injection - The next level

Have been very busy developing and testing more aspects of the water injection rocket that is RICESP

Can't divulge exact specifics *sorry* but a "quantum leap" in power is not a bad way to describe it, still on normal petrol and WM50. All same parts as listed to date, same engine untouched in last 2 years! over 12,000km logged on it to date.

The WI system is the same but with calibration changes to suit the very high power output increase over the last lot of shared tests. The only extra's are a change of secondary fuel injectors and fuel pressure changes to feed the engine more pump petrol ........... of which it needs quite allot at maximum rpm and throttle.

Next year will be even more again, But will have to install the upgraded drive line to cope with the immense RICE RACING power!!! Once this is underway I'll release this current specification on here for all to read and benefit from, trust me it is pretty amazing, mind boggling, warp speed, gag factor acceleration!!! all only available due to water injection technology

Nice "RICE RACING".
All that water ends up turning too "steam" If you start with that first with right flow rates the opposite will happen when consitering power loss with higher humid and temps.
