01mazda Posted November 25, 2007 Report Share Posted November 25, 2007 Didn't know where else to do this, But I'm new to the forum... jus bought a 2001 mazda milly i see they are called. Pearl white milly S with the miller cycle engine, Has about 88,000 miles on it and i got it for $8500. I have seen alot of topics and have already learned alot about my new car on this forum.... what I havn't been able to find is how much boost does this stock engine make? 2.3L thanks in advance, Greatr Forum!

///BHRpowered Posted November 25, 2007 Report Share Posted November 25, 2007 Welcome to the madnass In first gear you'll have 7psi, in all other gears its 14psi, This is controlled by the ECU Quote Link to comment Share on other sites More sharing options...
01mazda Posted November 25, 2007 Author Report Share Posted November 25, 2007 Welcome to the madnass In first gear you'll have 7psi, in all other gears its 14psi, This is controlled by the ECU has anyone done like a CO2 spray on the intercoolers or even methanol injection? does anyone know if all the internals are forgded! what is the most boost someone has ran on this motor... and is there a way to get max boost soon, it seems the full boost isnt until like 4 grand?

///BHRpowered Posted November 25, 2007 Report Share Posted November 25, 2007 peak power is around 3200rpms. I have water sprayers, and thats about it, the MCE does not like to be modded and its very very picky. The JET chip that some have can increase boost to 16, but thats the most i've ever heard of anyone running. The enigne does NOT like to be touched. The ebay chips attempt to raise boost, however the only person to try them had the ECU basically put the car into safe mode and wouldn't shift out of 1st gear until the chip was removed. Your best bets for power are intake and exhaust, on the FI engine it really loves the open flow Quote Link to comment Share on other sites More sharing options...
01mazda Posted November 26, 2007 Author Report Share Posted November 26, 2007 has anyone tryed CO2? if not why not? what do you mean water sprayers.....Any pics? where would i get exhuast, or even the JET Performance chip??? thast what your talking about right.

enginph Posted November 26, 2007 Report Share Posted November 26, 2007 Your intercoolers open at 4k rpm. You may notice a power boost depending on the weather. BHR are you sure about 3200 being the max s/c boost? I thought it is earlier. 7psi, wasnt it more? 01mazda move to a colder place and observe crazy power..

///BHRpowered Posted November 26, 2007 Report Share Posted November 26, 2007 max power is at 3200, boost has nothing to do with it, its 14psi in all gears except 1st, so to repeat because you missed it, 1st gear = 7psi, 2nd, 3rd, and 4th you get 14psi. I have no idea why it was designed like that, but a boost gauges on several S's don't lie You people are forgetting a basic aspect of how a MCE works, its not a normal FI jsut pushing more in, it needs a certain amount of pressure for a certain amount of thime, if you increase it you use less fuel and lose power. 01, water sprayers, a fine mist over the intercoolers to keep them cool, IMO far far safer, cheaper, and practical then ebay hyped C02 Quote Link to comment Share on other sites More sharing options...
Jdubs99 Posted November 26, 2007 Report Share Posted November 26, 2007 The miller is not dependent on gear selection for boost pressure last time i checked. You can still be at 1 bar in second gear. Quote Link to comment Share on other sites More sharing options...
Graham Posted November 26, 2007 Report Share Posted November 26, 2007 Dubs - 1 bar = (approx) 14 psi which is exactly what everyone above has stated for second gear. Your argument may or may not have merit but your evidence is way too poor to survive. Question: Are you claiming 1st gear gets the full 14psi (1bar) of boost ????? I don't know what the internals of the engine are made from, but considering that it's built for efficiency and not outright power, I'm going to suggest that they aren't forged, but this is just a guess. I'm not sure if you're aware of the dynamics of the Miller Cycle compression stroke, but the biggest difference is that it keeps the inlet valve open for the first part of the compression stroke. It's trading up in efficiency (not real compression while crank is at BDC and therefore less resistance) and losing ability to hold the fuel mixture in the combustion chamber. The supercharger compensates for this somewhat, but boosting it up may well alter the 'finely tuned dynamics' of pressure versus miller cycle process, hence why no one has reported much success in that area.

///BHRpowered Posted November 26, 2007 Report Share Posted November 26, 2007 There are 3 MCE's running around with boost gauges I can name off the top of my head. In 1st gear all of them read 7psi, in all other gears they read 14psi. I have no idea why, just stating what has been observed Quote Link to comment Share on other sites More sharing options...
01mazda Posted November 26, 2007 Author Report Share Posted November 26, 2007 well if the boost gauge reads 14 doesnt that mean its only 12..... I have always been told that boost gauges are normally off by 2 psi so that would make first gear really 5 psi??? Quote Link to comment Share on other sites More sharing options...
///BHRpowered Posted November 26, 2007 Report Share Posted November 26, 2007 I don't see why boost gauges why be off by 2psi, kind of defeats the purpose of accurate readings. That picture was taken at about 120mph though Quote Link to comment Share on other sites More sharing options...
mts Posted November 26, 2007 Report Share Posted November 26, 2007 That is OK, the one in the pic is reading 13psi anyhow. Quote Link to comment Share on other sites More sharing options...
///BHRpowered Posted November 26, 2007 Report Share Posted November 26, 2007 1psi at some speeds I coudl see, especially since that pic was taken just as it was beginning to shift. Quote Link to comment Share on other sites More sharing options...

street3890 Posted November 27, 2007 Report Share Posted November 27, 2007 If you wanna hear and exhaust and intake hear you go...This is my 99 milly s with remus muffler and 2.5" piping and custom intake and K&N filter provided by Chitown Quote Link to comment Share on other sites More sharing options...

///BHRpowered Posted November 27, 2007 Report Share Posted November 27, 2007 14psi, stop being a smart ass I do love that video though, ill make one some day. and no, the millenia is not a track car, if you want to race and go at a track or use old muscle car building, its not the car for you.

01mazda Posted November 27, 2007 Author Report Share Posted November 27, 2007 this is my family car but was just wanting a little more kick.... my track car is a 1990 mustang 5.0 with a 200 shot. I really want to know for sure if the pistons on this car are forgdeed or not because i would really like to do like a CO2 or nitrous spray on the intercooler and see what happens.... if they are for sure forgded myabe even a nice Dry nitrous shot with a custom tune Quote Link to comment Share on other sites More sharing options...
///BHRpowered Posted November 27, 2007 Report Share Posted November 27, 2007 it won't come anywhere close, and 90% of the mods you can do to that, you can't do to the MCE, either because they don't exist, or because it won't let you. There isn't even a production intake, short ram or otherwise for any millenia, a member here had to custom design one The ONLY performance mods for the millenia that exist are a drop in k&n filter, and the jet chip, everything eles is custom Quote Link to comment Share on other sites More sharing options...
01mazda Posted November 27, 2007 Author Report Share Posted November 27, 2007 you can do a custom CO2 sprayer on the intercoolers and almost all nitrous systems are custom??? and tuning is all custom so... just because A big name brand company doesnt make parts doesnt mean it cant be done, and that it wont make any power... there is just no demand! we will see what happens... I'm going to contact Mazda and see if they can tell me if they are forgded intetrnals, I really think they are because of the 14psi of boost! I am on my second year of autmotive training and i will tell you what.... Any thing is possable! OH and Nitrous is your friend! also you are using water sprayers on your intercoolers?????? why water? I would think that would be very unsafe? Quote Link to comment Share on other sites More sharing options...
