Na tujih straneh sem zasledil da na dragih na mazdah uporabljajo vodo ki jo vbrizgajo pod pritiskom nad 9 barov v sesalni del pri filtru.To naj pove?a mo? okrog 30% .Pi?e da voda mo?no ohladi vstopni zrak, zato mora? v vodo dati tudi majhen procent metanola(ali podobne snovi) da ne zmrzne in se ne nabere na stenah.
?E JE KDO ?E SLI?AL ZA KAJ PODOBNEGA NAJ NAPI?E!!!!!!!!!!!

Aquamist and Water injection;
Aquamist injects water into the inlet system somewhere under pressures up to 145 psi or 10bar. This has the affect of increasing the knock resistance of the system by removing heat ..however it also displaces oxygen molecules and so reduces the potential energy available .. hence less power. So there is a balancing trick going on .. add water to reduce the knock .. then advance timing to extract more energy from the mixture (if your spark goes off at TDC it is too late and most of the energy is wasted .. you need to do it up to 40 BTDC to allow the peak combustion pressure to occur at or just before TDC .. this maximizes the extraction of energy). Hence water injection is good for a fixed displacement supercharger (it cannot displace oxygen and pulls lots of heat out of the system ? so more oxygen in a cooler form gets into combustion chamber).. but be warned that when the water runs out.. your engine will knock and over heat very rapidly .. so it is considered a dubious system by many professional turbo installers. (I?ve got it .. maximise the knock resistance with higher boost pressures on cheap fuels while retaining stock CR for off boost response/torque at sub 2000 rpm) See here anyway; http://www.aquamist.co.uk/
"It seems water injection knocks the peak off the pressure spike. The pressure plateaus instead of peaking. This is if I was looking at a graph of the cyl. pressure. The burning will be extended so advancing the timing while injecting the water should be done to compensate for the slower burn. As the engine revs the water injected will stay the same while the air flow increases. In other words, the water will 'lean out' at higher rpm. Don't drown the engine by using too large of nozzle. The water can be used to increase boost or timing. I like to think of water injection as "artificial octane". If you spray the water before the throttle you must use some alcohol as an antifreeze as the throttle could freeze open. Because of the suppressed boost spike, I believe the water injection will be easier on the head gasket than without it. Also, I saw a pic of a disassembled Miata motor that used water injection. It was free of carbon! Another battle won against detonation.
My unit is home made and I use a 50/50 mix of water and methanol. I inject 150cc/minute of the boost fluid starting at 4 psi. The Aqua Mist should be setup downstream of the IC to allow the IC to work with some differential temps before the water/alcohol mist cools it further. You will need some alcohol because of the possibility of the throttle freezing open. Always use distilled water so minerals don't build up on the nozzle. The nozzle should be the smallest possible. I'd suggest getting a .4mm as the smallest offered is .5mm with the kit and there is no benefit in drowning the engine. I only inject 75cc/minute of water, the other half is alcohol,
a 118 octane fuel. You can (and should) advance the timing 2* to 3* for each 100cc of water injected.
Here's some COOL numbers I came up with from an engineering book. Gasoline, at stoich, cools the charge 40*F. Methanol, at stoich, cools the charge mixture 300*F. I think water cools 3 times what methanol does per
"Being only the person on the list with a turbo that uses water injection on a full time bases now I thought I would speak up on the subject. First I don't use just water as to reduce knock. I use water/methonal mix to reduce EGT which is the problem with any F/I engine being rotary or piston. It is not the pressure loads that destroy engines it is the thermal load that burn valves and rings. If you increase the pressure the heat must also increase, but by using a water/methonal mix my intake temps at 19 psi of boost never go 10 degrees above the outside temps and often remain cooler then the cabin temps. At 17 psi and the biggest intercooler that Corky sells for the miata the engine will ping from time to time And any pinging at all is not acceptable. At 19/20 psi of boost with water/Alcohol injection I get no pinging at all and you can feel the water kick in at 12-13 psi of boost. And you feel the water increase with an increase of torque. I don't recommend the Spearco unit; I and others have used the
Aquamist water injection with great success. Yes it would be better if I used 110 octane gas. And also while the car is running in N/A mode (most of the time on the street) the 110 octane gas is not best in the world for the engine. Further at 5-6 dollars a gallon gets a bit pricey after a while. There are other ways to decrease intake temps, but often these increase EGT. Which in turn kills your engine. Having a sliding scale for my the octane of my fuel. I have the best both a lower streetable octane with the some of the benefits of race gas. Believe or not there a lot more cars out there with water injection but they just call it an EGR valve. A major part of the exhaust gas is water used to reduced EGT. Which allows high compression engine to past emission guide lines. Which are becoming more and more common even with turbocharging!!" root root@localhost.localdomain
bil v GMT in kupil modre LED za pozicijske.Vozil sem se mimo policajev pono?i ve?krat pa ni?.COOL.
Vgradil sem tudi ve? LEDic v vrsto na notranji strani pod nogami ki svetijo na pedale.Pono?i zgleda dobro.Moram z digitalcem pono?i slikati .
Amaturko sem preoblekel v belo usnje, (prej pobarvano, pa je delovalo preve? plasti?no).Dela dosti, precej z********e, vendar se spla?a.Zgleda fenomenalno.
Slike pridejo ?imprej.

mazda 6 ma ?e pu??eno serijsko tudi na levi strani za izpuh.Tako da bi lahko mel na vsaki strani enega.?e ti ni dale?, ti naredi vredu izpuh, ali pa nastavek gor v Murski Soboti na ?koda servisu.Tam se en tip samo ukvarja z izpu?nimi sistemi.Meni je delal kompleten izpuh na 323c pa je narejeno vredu.Pa niti ni drag.Ma pa ?e tam nekaj nastavkov.

jaz sem kupil v HTE.Modre pridejo 400sit, druga barva pa po 80 sit kom.dobi? pa jih v dveh izvedbah, ene ki svetijo v snop in druge ki razpr?ijo svetlobo.Vidi? po tem kako dale? sta oddaljeni elektrodi od le?e.Jaz mam rde?e notri.
Ti si mel notri modre pravi?, kaj pa z policaji nisi mel nikdar problemov ?

zamenjal sem ?arnice v vratih ,pozicijske lu?i,... skratka vse kjer so 3W3 in 5W5 ?arnice z LED diodami.Ker so originalne za zamenjavo drage (okrog 500 sit do 1k sit ena) sem jih sam priredil za 12 V napetosti.Od uni?enih ?arnic sem vzel podno?je, tako da sem zgornji stekleni del odlomil.Na ?i?ki kjer je prej bila ?arilna nit sem prispajkal DIODO.Ker dioda ni narejena za 12 V sem med katodo diode (?e pogleda? diodo od znotraj ve?ji del) in eno ?i?ko na podno?ju prispajkal upor 560 Ohm.Upor je majhen mo?i 0,25 W saj tu te?e majhen tok.Nato sem zaradi robustnosti zalil s teko?o plastiko (pi?tolo ki greje plastiko) od diode pa do podno?ja.cena izdelave ene diode je sedaj 89 SIT (80sit dioda + 9sit upor).

mislim da bi morala ?rpalka zdr?ati, na peugeotu 306 ki sem ga mel prej sem pove?al tlak za 1bar,pa ?e zdaj dela ?rpalka,to je ?e 3 leta.Mislim pa da majo japonci bolj?e ?rpalke,tak da bi moralo zdr?ati.Druga?e pa ?e crkne jo lahko kupi? v avstriji poceni na odpadu.Huj?e je ?e gre ?rpalka v prazno, ko ti zmanjka bencina.

bencinsko ?rpalko mam to ki je ?e bila notri, serijsko.Na manometru sem gledal pa ?e zmore taki tlak kot mam nastavljeno.Misli? da bo odpovedala ?Saj nimam tak mo?no tunanega avta da bi rabil toliko ve?ji pretok bencina.

pod pokrovom je ja, ko bom ?el na tehni?nega bom dal nekaj prek da se ne bo videl manometer, druga?e pa so tu pri nas tak zabiti da ?e haube ne znajo odpreti.

stane 175 euro (okrog 40k SIT) .Je pa za vse mazde enak (enak pretvornik) ,da pa se poljubno nastavljati.Pospe?ek je pri meni ob?utno bolj?i, pozna pa se razlika ko se motor segreje da zdaj bolj potegne.Koliko mo?i pa je zraven dalo pa ne vem, nisem dal na valje merit.Mislim pa da bo zdaj poraba malo ve?ja ?e bom gonil kot zdaj.

Kupil sem nastavljivi regulator za tlak bencina z manometrom iz kataloga autostyle 2004.Tlak sem pove?al na 6 barov in v kombinaciji z ?portnim filtrom se ob?utno pozna da avto bolj pospe?uje,odzivnost je zelo dobra.Kaj menite kak je s tem pri tehni?nih pregledih, ali je dovoljeno ali ni ?

pri ekstremnih obremenitvah ti lahko disk raznese.originalni ?portni diski z zarezami nimajo zarez ven zbru?enih ampak so tako uliti in po posebnih postopkih kaljeni
