So Boosting Our MSP's is not good..??

[Captain KRM P5]

Which would mean that a CAI/FMIC/full exhaust with 14+psi would put you near the limit right?

might as well get the downpipe as well. regardless, none of that is worth anything long term if you're not taking care of the fuel issue.

 

[low_psi]

The guys who SCCA the N/A protege are making 250hp and I hear they are replacing engines three times per season. I wonder if that aMount of HP is the practical limit of this engine. Which would mean that a CAI/FMIC/full exhaust with 14+psi would put you near the limit right?

The reason they are replacing engines is the rev-range they stay in through-out the race. They reline around 9K i believe. There's lots of info floating around if you want to look more in-depth into the matter.

1 race mile = 1000 street miles -quoted from a Porsche racer. Its not 100% true, but you get the idea of the hell those engines go through.

Terry's MP3 is probably running 260+whp with a decent clutch. He's proven Mazda and Mazdaspeed wrong with their assertion that the stock FS-DE bottom end can only take 250whp. Engine management is the key to keeping your rods; connecting rods.

That's the spirit! (2thumbs) (rockon) (2thumbs)

yashooa, how often do you even go into boost? i remember in previous posts you told us how you stay between 10-18 vaccuum through most of your driving life anyway. shrug.

 

[DiscreetSpeed]

spoolin's mp3 also had alot more done to it than any mazdaspeed protege - correction, any protege - on this board. "supporting mods" in that case would begin with throwing the stock ecu out the window.

WITH STOCK INTERNALS, that was the point of my post!
supporting mods....what would you call it..??

 

[unwrittenLaw]

I just got my MSP and I like the car but at the same time I am dissapointed..The thing that gets me is how the HELL can mazda make a turbocharged enthusiests <sp> car and NOT use forged internals!!!Thats a pile of dung if you ask me..Just makes me mad to know that to make the car fast you have to do what mazda didn't and should have done from the beginning..Mabye its just me and my being used to making over 400hp on a 2.0 dohc thats over 12 years old and bone stock internally, but this is going on 2004 now WTF?!?! The focus SVT even has forged internals and its not even TURBO!! IS this just a regular protege motor or what??Whats different??

What type of forged internals does the Focus SVT have? I doubt they are like true aftermarket forged internals, but I don't know much about those cars....

 

[iNeedSpeed]

ok now...............ive been been boosting @10psi for 4 months now with no problems........i will be backing back a lil after reading this but only to about 9. at least my car is fun!!!!

 

[yashooa]

You have one of THE most incoherent, incomprehensible typing styles I have ever seen.

If you think my typing is bad you should hear me speak...
I sound like a mix of that Tard out of Slingblade and the Godfather.
I'll make you an offer you cant refuse... ahum I'll study on ya fer a while, I will. Why does my jaw hurt?

Usally just through the bottm two gears in the morning. I leave at about 6-6:20 am and get to work about 7:35. I normally spank it a bit down the back roads so I am in the boost to some extent in the morning. On the way home I just hit it coming out of the parking garage. There is a great lauch spot right a redlight it's like my own staging tree in dowtown FT.WORTH
You can get a good 1-2 shift max boost launch, then around a sharp right /left decending S-turn, down a short straight coming back up out of the descent, then quickly dart across two lanes to the far right hand lane, accellerating uphill towards a long sharp right ,up then down the steeply descending accelleration lane into the 4:30 pm I35 South traffic.
So at least a few times a day just not whilst I drive home for most of the 42 miles. Well except today when I redlined it third passing some ASSMONKEY that was blocking the fastlane. It was fuuuuuuuunnn oh yes it was.

 

[yashooa]

I think you should take the turbo off ENTIRELY! No boost is safe boost thats what I always say!

heheheh Yeah the only good turbo is a DEAD turbo. Those thangs are ******* evil I tells ya E.V.I.L. !!! (laugh) (laugh) (laugh)

The turbo is a tool of the DEVIL!!! Beware friendS, Romans, Assholians, BEWARE!

 

[BLURSPEED]

I've been boosting 10psi for about 3 months now and no problem. Only problem I encountered was fuel cut since the temps dropped but that problem has been solved with Joe's FCD. Thank's Joe.

 

[BLURSPEED]

Oh and my performance mods are XS engineering intercooler core, custom 2 1/4 mandrel bent pipes, turbonetics hoses, greddy type s bov, ngk bkr7e copper plugs, protsport downpipe, custom 2 1/2 inch exhaust piping, tsudo carbon fiber titanium tip muffler, joe mbc, and joe fcd.

 

[DiscreetSpeed]

DO NOT BOOST MORE THAN 7PSI ON 93 OCTANE.......lol

 

[BLURSPEED]

I haven't had any problems yet. This is my 3rd turbocharged car and never had any problems with running 93 octane. Actually I'm usually running 91 because I get my gas on the Air Force base. My 2 other turbocharged cars were skyline's when I was stationed in Japan.

 

[BLURSPEED]

One thing that I don't do is run anything higher than 10 with 91 octane. When I run 13psi I go to Rebel gas station and use their 100 octane racing gas.

 

[DiscreetSpeed]

DO NOT BOOST MORE THAN 7PSI ON 93 OCTANE.......lol

you will blow your engine.....if you do...

 

[BLURSPEED]

No I don't think so. You may think that it will. But for 2 years in Japan my RB20DET motors never blew. As for the MSP I've been using 91 octane since I had the car. 91 is considered premium which is the lowest you can go. Now if I was putting in 87 or 89 then I definetely would agree with you. Detonation would then occur.

 

[BLURSPEED]

With all due respect to you bro, but I'm not new to all this. But yeah we're all entitled to our own opinions. I don't want to start a flamewar or anything. You're actually looking out for a fellow MSP owner so it's all good.

Man Discreetty is just playing the Vagina's advocate. He has been boosting to 12PSI from damn near the get go, HO

 

[Brian MP5T]

Swoosh...Boom!

DO NOT BOOST MORE THAN 7PSI ON 93 OCTANE.......lol

I agree, unless you have looked into the "weakest link problem". Intercooler, fuel, spiking. Etc. Once you have these problems covered, you should be able to take it 7 or 8 Daily and 10 -12 for track day. Expect to blow motors, the stock set-up wasn't designed for you guys to start playing with boost. That's why it doesn't come with a boost controller. If you want Lotus or Porche performance from your car you really should just go buy one.

The Protege was designed as a fun way to get you to work in the morning, not to pass jet planes.

Later...Brian

If you boost, you have to improve the design that Mazda has made to compensate for the added load that you are asking of your internals and drivetrain.

In the end, the bottom end (rods in particular) are good for no more than 230-240whp (105mph trap speeds). Not bad, mid-13s capable. But then you're at the limit. Proper tuning or not. No one can dispute that. Many would be happy there, but I personally wouldn't be for long. That's why I'm selling my car. Don't feel like spending $3500+ to build a Protege motor. The next car is also a 2 liter 4cyl that comes with a T25, but it's stock bottom end is capable of 475+rwhp and doesn't have a retarted ECU... and is RWD.

Yes, I bought the wrong car to play with, but it was fun while it lasted.
