Fuel cut off???

[Rac3rX]

dude, you have a post count of over 1500 and you doing this childish s***??
you are doing the "MINE DICK IS BIGGER THAN YOURS" skit...

It seams I cant make a post without him talking some sort of s***, its unfortunate that he cant let things go, but I simply REPLY, when he does (And will continue to do so) If you think thats imature (Enough to call me "Stupid") you should direct your comments at the source .

show some maturity by just ignoring him, and even banning him...but doing what you just did is plain stupid....

If I could ban him, beleve you me, it would of been done a long time ago, all he does is bash others and act like his s*** dont stink.. Kinda like what your doing right now, bragging about every single little street tustle you have as if thats mature & Replying to a negative comment is worse (At least my replies dont put inocent life at risk...........)

OR if your going to be the MATURE one, give your advice without the grain of salt "but doing what you just did is plain stupid", Because doing what you just did is plain stupid. (Kinda pisses you off doesnt it...)

i read all thru your post and you were going in circles...if you noticed the hello kitty s***, you are just paying too much attention to this guy

Rants usually do, big deal, the message is clear, and #1 its kinda hard not to notice the Hello Kitty s***, its in his Damn Avatar But beyond that, this is far from the first time hes gon off talking s*** (Evident from the post of mine you quoted) Its hard not to pay a little attention to the retard in the corner flapping his arms squocking like a chicken......

let him be...

Why arent you talking to him? Did I start this s***? If you feel the need to comment twords ME why not comment twords HIM????????????????? Yeah, "Keep it fake" is how you roll!

just a my .000002 cents

You got that right!


Now lets see you Practice what you preatch........

hondas rev higher than the fs-de
fact
To note I posted in this thread 2times before you. How exactly that is posting inflamatory things at you is beyond me. And if you want to have a (un)populartiy test set up a poll. Atleast I'm not afraid of what people will think of what I have to say. Or care for that matter.I'm probaly saying what most of the members reading this post are thinking there just being to nice to say it.

And finaly You drive a protege. Its not a drag car.
but I do apreicate you telling me how fast my car is.

You play dumb soooo well.

Your "RicerX" s*** when quoting my name DUMBASS!!!

Im NEVER afraid of what people think when I say s***. Its your Ass who finds the need to start s*** (I never Spoke to you in this thread UNTILL YOU called me "RicerX") So GROW UP!!!!

 

[Rac3rX]

Atleast I'm not afraid of what people will think of what I have to say.

Yeah, THIS is what people think of you.....

Dude im not trying to flame you.... But you are always so freakin negative. All you do is bash people. And you (from what im seeing in this thread) havent even thought out your case. Really these remote mounted turbos work very well. I cant wait to see this one in action after he has worked out the kinks. Thats just my 2 cents

 

[Rac3rX]

Huh?
This is your response to my on topic response?

Okay, "Your on topic response" is dumb, Here Ill break it down for you...

The Charge pipe having to be piped arround in the engine bay & through a intercooler is NOT drastically shorter then the charge pipe in the remote mount set up seing as it Doesnt need to be intercooled and or be piped arround the engine bay. The Turbo breing in the rear seriously reduces the heat issues usually found with under the hood turbos. Turbo Lag? Did you not read my other post? "Turbo lag is eliminated thanks to a significantly larger turbocharger than what would be used in an underhood application" coupled with the Diff in lenths not being as drastic as one would imidiatly ASSUME, like you just did.

There is also the FACT your other post was foundationless...

-Your not going to have enough exhaust gases to spool it effecent(4000rpms isnt effective unless your engine revs to say 10k). PERIOD. espicaly if you have the stock exhaust system just cut off at the muffler.

Blackrose had to explain it to you...
"There will be the same amount of exhaust gasses at any point in the system... unless there is a leak. There wont be any real pressure drop issues either."

So **** you Revs bulls***........ We are talking about making boost, NOT making it at the lowest possible RPM... So long as he makes boost.

But Ill have to also explain something to your clueless ass.... This IS NOT a Remote Mount Turbo Vs Conventional Turbo Thread.....Dumbass! His goal in no way is to out performe a Conventional Turbo, he wants Boost, and unless the remote mount turbo DOESNT WORK AT ALL, NONE of what you say has any relevance!!!!!!

 

[Rac3rX]

his charge pipe also goes under his trailing link. is this smart?

Depending on the quality of his install in can be just fine...

he's hitting 2psi at 4000rpms. Thats working?

Before the MSP ECU....

Umm he hasnt ironed out all the kinks in the system yet....I thought that was evident (Ohh and that 2psi was when he was using the N/A ECU) hes now on the MSP ECU, that runs her to arround 5psi, But the kinks arnt out, thats why he made this thread......

he has no form of engine management.Does that sound well though out?

He has the MSP ECU, and plans to make the Same boost as a Stock MSP (Wait, hes looking for 6PSI) Im pretty sure hes fine W/O Engine management for that......

There are restictons after the header.
Precat. cat, silencer.

I havnt seen his exhaust system, but I would geuss hes running catless (Or soon to be, or plans to be) I would also have it all as un-ristrictive as posible (Hmmmm thats un common) But catless (Even with Cats), he should have enough exhaust flow to spool her up BEFORE he reaches red line. Like I said, his goal is to make boost, so long as he does inside his powerband its working....

If these things dont slow exhaust gases I will no longer be emo.
Please explain how these dont restrict flow?
My response was to

this s*** came from no where. It pertains to nothing.

Your making alot of assumptions, do you do this often?

Why would you assume if he hasnt already he intends to complete his set up by removing all the restrictions you speak of from the exhaust set up? And dont act like they cant be... With that said, Whats Your ******* Point???

(help)

None of that really matters, he wants to make LOW boost, not CRAZY retarded high boost.

 

[Blackrose]

Buhavis....

Anytime people do something new there will always be haters out there trying to tell you its not going to work.. Well there are benifits to a remote system over a front mount and vice versa. Did you ever get the FCD. I am really interested in seeing this thing in action. PLease keep this thread updated and try to get more pics and sound clips.

If you got any questions hit me up on a PM and i would be more then happy to help you out however i can.

[ZZZOOM!]

Man bottom line I just got to give you props for having the huevos to try something new.
Look I drive a car that stock will barley keep up with a new chevy cavalier (straight line). So if I get 1 more hp out of it and have fun doing it thats all that matters right? We all have the same thing in common...MAZDA!

BTW If I want to use extra tire pressure in the future to boost my motor and find a way to plug it all up I don't want s*** from anyone ok guys?? I'll be sure to post pics and video!

I just want to let you know that i took out the cats and the silencer so its a straight pipe to the turbo. But hey thanks to all the people out there that beleive that i can do this and helping me with it. Its kind of hard because noone knows about it but it wont be long till i get it done. And honestly this thread has just turned into people yelling at eachother. It's kind of stupid. I just wanted to get some opinions on why it was cutting out in me so i could get it done and show you all some vids and stuff. So if anyone has any ideas please let me know. Thanks!

Thats what I thought you would of already done. I cant see everything in the pics, but if you did the charge pipe, you can do the exhaust...

With that I cant wait to hear the thing, must be loud as hell and piss off all your neibours, Ha ha ha ha ha.... I have a feeling Im going to love it.

Good luck figuring it out. Not much help is one of the reasons new directions are dificult, but you seem to have a good enough idea of what your doing to get over your obsticals, Good Luck.

Dont let the Haters get to you, they are a dime a dozen and polute every aspect of the world.

More info will help shead more light

Do you have a boost controler? (Im not sure) That would be very benificial

Do you have a Boost guage? (Im geussing Yes)

Have you been getting boost spikes? (High enough to trigger a fuel cut? I wouldnt think so) so the FCD wouldnt be of much use, I wouldnt think, especiallly if your using a MSP ECU and only intend for 6psi.

If you have a Boost guage, what are the boost readings at multiple points in the rpm range?

When you say "the car is trying to shut down on me at 4500 rpm as soon as it hits boost"

"trying to shut down on"

Is that a car strugling OR Dead pedal, type shut down?

Dead pedal, where you feel like there is NO GAS being given as you push the pedal, & Car strugling as in the engine feel like its going up a hill with too much weight.

Are you making 0 boost untill 4500rpm (THats alot of lag, way more then expected) Sure there is no leek in the exhaust line to the turbo?

Also when you hit boost at 4500rpm, is that 6psi? Or assumed stock MSP boost?

Also Maybe a small turbo has too much work to charge up the intake charge pipe, a bigger turbo would help the lag in that case (little diferent then conventional)

 

[02PROTEGE2.0]

wow.

i think as a mazda communtiy our objextive should be to support new ideas.

this guy is no engineer... he's not gonna make a perfect set up.

lets give him some time to perfect.... and maybe he'll bring something good to the community... maybe he won't.

but my hope is that this will be a good session of trial and error until it
A)works better for cheaper than we could ever imagine.
B)doesn't work and shows us that this is not the route for our cars.


so lets find out for ourselves...


hey maybe a supercharged protege is in order? hahaha....

ill be the first pro with a blower!!!!

Too late for that someone here is supercharged.... i cant remember who it was though.

I've been thinking about doing this to my Dodge Ram for awhile now. Very cool and very original.
Now to the problem at hand. You said it is running very rich, why? If you are running the stock msp pcm it shouldn't be running rich unless you are full throttle.
Next are you sure it is fuel cut? An easy way to figure out if it is fuel cut is to tap the center wire off of the maf sensor with a volt meter. One lead off the meter to the center wire (green/black) the other to ground. Put the meter somewhere so you can see it when you go for a ride. Go WOT and see if the voltage gets anywhere near 5v. If it hits 5v it is fuel cut. If the voltage ramps up very fast to anything near 5v it still could be fuel cut as the pcm anticipates its going to hit 5v.
If its not fuel cut, check the gap and condition of the spark plugs. You could be blowing out spark, especially if you are running excessivly rich.

Make sure you have the maf sensor in the correct way. Arrow pointing to direction of flow.

Good luck man.

 

[buhavis]

Hey thanks guys ill try all your ideas hopefully ill get a chance to do it today. THen ill let you know what happens.

 

[buhavis]

Well. I think ive narrowed down my problem. I hooked up my timing light and i found that when i hi around 3500 rpm my signal stops. I dont get any spark after that. It will get a flash every now and then but barely. So now im trying to figure out why. Has anyone had this happen? Also i want to check the voltage on the coils but i dont know which wires are which. Does anyone know which one is the positive, ground , and trigger ont the connecter that plugs into the coil?

 

[plrubin]

Stupid question but was it as expensive as a normal engine mount turbo?

 

[peepsalot]

I just saw this thread. Very cool project.

Did you ever get this thing figured out? It does sound like "fuel" cut. By the way, people have gotten the habit of calling it fuel cut when in fact I'm pretty sure the ECU cuts the spark, not the fuel(or maybe both at the same time). So that would agree with your findings that the there is no spark. The ECU does this when it sees too much airflow in the MAF. That's why blkzoomzoom said to check the voltage coming out of that sensor.
If fuel cut is the issue, the only real solution is getting an EMS(and probably larger injectors) to handle it.
A fuel cut defenser is always a bad idea IMO because you run the risk of running lean --> detonating --> zoom zoom boom.

Also, if there is any leak after the MAF, then it would be seeing abnormally large amounts of flow and giving fuel cut before it's due. So I'd check for leaks.

What amount of boost do you see when it happens?

The key trade-off in this set up (why don't all turbo sys designers do this?) is that exhaust gas VELOCITY (accelerated hot gas from expansion) not VOLUME drives the turbo by impingement on the blades. Velocity decreases as the exhaust gas temp decreases (assuming constant area i.e. same dia. piping through the system).



So - it is by no means 'optimal' as a location, but if it was *significantly* cheaper (like $400) over a $3K system - i would def'ly consider it. If it gave a signifcant boost in WHP like 50% of a 'conventional' kit...

I would absolutely find a better place for that intake ASAP! Don't wait for hydrolock, or sand to stick to the oil in the filter, or for a bump to rip it off, or.... Move it up to body/behind the rear fenderwell area and get a bypass valve.

It will hydrolock if it is submerged - the engine will continue to suck/draw water until it fills the cylinder - the distance doesn't matter...


All my $.02 worth... (i do have a Masters in Engineering and do propulsion design... But not for cars... So, whutEv3r!)

I was riding with my brother this weekend and we are still having thet stalling problem and it has to be a spark cut because the car runs rich at full boost. ( by the way it was hitting full boost 6 psi at 2500 rpm, hardly any turbo lag) The car starts the hesitaion at about 4500 rpm and if you hold the gas will never get through it, gas is to the floor the car is at full boost but is not increasing in spee d. We origianally left the iat sensor hanging and we were hearing a weird whining type noise coming from the turbo when pushed hard. I took it apart and inspected the turbo and its fine, so we drilled a hole in the charge pipe and reinstalled the iat sensor and now the whining noise is gone and may be running a little smoother but still hesitaing. we still have not checked the MAF but wikll hopefully get to it this weekend. I really think this car could be quick if it didnt hesitate. If any one has any suggestions please post them cause this hesitaion is driving me crazy cause i really want to see it run good. By the way we are running the MSP ecu but when we put the stock ecu it does not hesitate but i dont want to run it for long on the stock ecu.
