my mazdaspeed intake problem

[turbofever]

Apples and Oranges. The engine is a lot beefier and it has a close ratio 6 speed. This car is not a MSP Protege, not even close.

This is true.

You can floor this car in sixth and fifth and pull like crazy.

Your speed 3 must be special. I know if I go WOT in 6th the car feels like a complete dog.

On the highway, there's usually no reason to get out of sixth, even for quick passing.

I didnt realize quick passing required you to go WOT.

The problem has absolutely nothing to do with flooring it in the higher gears.

It has everything to do with it. If you used the correct gear this problem wouldnt exist.

It's most likey an issue with the ECU pulling boost for whatever reason.

Yup, that is the problem, it cant compensate for stupid.

I held back saying this for a while, but this forum is a haven for misinformation, jeez. And it's so funny and surprising to see people just suck it up.

Very true.

This is true.

No, your speed 3 must have a problem. And I'm willing to bet that problem is between the seat and steering wheel.

I know if I go WOT in 6th the car feels like a complete dog.

Learn to drive or take your car in for service. At highway speeds 6th gear pulls. Notice I said highway speeds, and that's where the OP was having issues.

I didnt realize quick passing required you to go WOT.

Who said that?? The voices in your head?

It has everything to do with it.

With what? The ECU pulling boost?. Stock the car doesn't do it and other people with CAIs aren't having issues so quit talking out your as*!

If you used the correct gear this problem wouldnt exist.

Quit listening to those voices in your head.

Yup, that is the problem, it cant compensate for stupid.

Then sell your ms3(if you really own one) cause it's hopeless.

your not suppose to fully spool the turbo in overdrive gears such as 5th or 6th. If you do this the car is sucking in a massive amount of air while you are at low rpms and this can cause problems. If you constantly do this you could end up in the zoom zoom boom club which is very well known by the MSP guys.

this is not true !! the turbo actually works less boosting at lower rpms.
thats one of the great thing about a turbo car... not having to downshift to take off.
i tried the stock bpv... no luck.... i am now using a forge bpv and LOVE IT !!

So, the new blowoff valve got rid of the problem?

This happened at 3000rpms in 5th gear, go figure.

Yup, theres nothing to be said about the tremendous load on the turbo while WOT in overdrive.(drinks)

 

[dread]

You lost your turbo?

 

[gsrtype1]

did youose your turbo becuase of thaty/?

(eek2)

I'm experiencing the exact same issue described in the OP. I don't remember noticing a problem before the CAI was installed. Then again, I didn't notice it happening immediately after. It feels like the boost is going up and down until I get going way too fast and then it smooths out. It doesn't effect regular driving so I wasn't going to worry about it, until I had to go into the dealer next, but if there was a solution posted I would sure be interested.

An aside, people get ugly towards each other, on this forum, quicker then any short of YouTube. Any theories on why?

like i said in my earlier posts....do not boost in overdrive or else you will eventually end up like that guy who posted a pic.

 

[BHOUST528]

exactly read my post above, you should not fully spool the turbo in overdrive gears at low rpms....this makes the engine work very hard.

What is with you people and not liking to downshift....drive the car like it was made to be driven....overdrive is for cruising and saving gas. Flooring it in OD does nothing for you except accelerate slow.

Just like in an automatic....when your not on the gas it goes into overdrive and when you floor it, the trans downshifts to accelerate faster.

Your exaclty right that was the same in my pt cruiser turbo i had if i had it in 4th gear while in the manual mode it would not down shift and the thing would accelerate very slow but i would always downshift...Drive it like you stole it you didnt buy a turbo car to cruise around in OD all the time when you need to pass just hit 3rd or 4th and step on that b****! hince the name ZOOM-ZOOM!

That's more than likely an MS protege's turbo / engine in pieces. And yet no mention of what possible mods that poor car had, yet we're supposed to believe it because it's a pic, LOL.

I'm still trying to figure out what that has to do with this thread or the MS3 though.

This isn't the ms protege section. Doesn't apply.

It's no use arguing with these guys man. After all they owned ms proteges,
and you know how strong that motor was.


Back on topic:

I'm going to start a poll on the other forum regarding this issue to see if it affects more than a few with the ms cai and if it's just an MS cai issue.

 

[tru-boost]

its simple people.... the fact that your turbo failed at 3k sucks, but that was not the cause.
think about it. it is much easier for the turbo to feed 15 psi to the motor moving at a slow 3k. it has to work its ass off (and do a bad job at it ) to try to feed that much boost at 5k and above. this is why your boost falls off at 5500, cuz the tiny turbo just cant flow that kind of cfm.
full boost at low rpm loads the engine hard but not the turbo.
that is what a wasegate does...... prevent the turbo from over working or overboosting. all the excess exhaust is routed through the WG and not the turbo. boost in overdrive is fine ... none of my other 3 turbo cars ever had a problem.

 

[turbofever]

Turbine speed isn't what I'm referring to, PR vs. LB/min is. Boosting 20psi while at 3k rpm I bet youre flirting with the surge line.
