msp topspeed

[Boosted_Speed]

whats the top speed on the msp and the rev limiter

[njaremka]

the msp should be gear limited to about 130-140mph

[fr0st]

220 km/h at -20 degrees on an icy highway with snow everywhere..in the dead of winter..

i know.. don't ask

[slo03.5msp]

143.3 mph on my gps before it would shutdown.

[fatti03msp]

i got to 137 and lots of gear left lol, but i think rev limiter is about 6800 rpm that roughly what it looks like on my dyno sheet.

[SleepyMSP]

hit 220 KM/H mid-day summer heat....was at 5500-6000 in 5th so probably could have hit higher....but would never do that again on a road....

[special--k]

^^ just about the same. And i would also never do that on a road again. Not with the new Speeding laws in QC

[Prodigy]

143.3 mph on my gps before it would shutdown.
142.8 for me.

[SleepyMSP]

^^ just about the same. And i would also never do that on a road again. Not with the new Speeding laws in QC

hellz no....its still lighter than ontario....>50 KM/H over you get: 10,000$ + 1 Mo. suspention + 1 Mo. Car Impound (which costs almost a grand to have released because you pay by the day). All on the side of the road....so if your in the middle of nowhere = (ughdance)

[Prodigy]

Just keep up your speed,
It'll take at least a minute for the cop to make it to to where you were + more time to make up the distance that you've covering.
You'll have enough time to take the first exit ramp and take cover.

Not telling you to speed... but you have enough time to get out of site.

[Ricktalife]

lol....RUN!

[magnumP5]

What's the gear ratio in 5th gear? Knowing the rev-limiter is 7250 RPM, your tire diameter and the gear ratio of the car you can easily calculate the maximum theoretical speed. This of course may not be obtainable due to things such as friction, drag, etc.

[Rogue]

This is using a 205/45/17 tire

Top speed = R / T * C
R = RPM (7200)
T = Tranny ratio
C = Circumference of your tire
((((205mm * .45) / 10 / 2.54) *2) + 17in) * pi = 76.227 in = 6.352 ft

205mm is the width of the tire
.50 is the aspect ratio, which is the relationship between the tire's height and it's width
/ 10 is to convert from mm to cm
/ 2.54 is to convert from cm to in
* 2 for both sides of the rim
17 is the size of the rim
the total Diameter of the tire is 24.263 in
using the formula C = D pi

1st Gear
T = 3.307 (1st gear) * 4.105 (final gear) = 13.575

2nd Gear
T = 1.842 (2nd gear) * 4.105 (final gear) = 7.561

3rd Gear
T = 1.310 (3rd gear) * 4.105 (final gear) = 5.378

4th Gear
T = 0.970 (4th gear) * 4.105 (final gear) = 3.982

5th Gear
T = 0.755 (5th gear) * 4.105 (final gear) = 3.099


1st
R / T = 530.387 RPM (at the wheels) * 60 min = 31,823.204 RPH (at the wheels)
Top speed = 31,823.204 RPH * 6.352 ft = 202,140.994 ft/hr = 38.284 mph

2nd
R / T = 952.255 RPM (at the wheels) * 60 min = 57,135.300 RPH (at the wheels)
Top speed = 57,135.300 RPH * 6.352 ft = 362,923.423 ft/hr = 68.735 mph

3rd
R / T = 1338.788 RPM (at the wheels) * 60 min = 80,327.259 RPH (at the wheels)
Top speed = 80,327.259 RPH * 6.352 ft = 510,238.750 ft/hr = 96.636 mph

4th
R / T = 1808.137 RPM (at the wheels) * 60 min = 108,488.197 RPH (at the wheels)
Top speed = 108,488.197 RPH * 6.352 ft = 689,117.027 ft/hr = 130.515 mph

5th
R / T = 2323.330 RPM (at the wheels) * 60 min = 139,399.806 RPH (at the wheels)
Top speed = 139,399.806 RPH * 6.352 ft = 885,467.570 ft/hr = 167.702 mph

Using GPS and Radar machines, a 215/45/17 tire is the most accurate in relation to our speedometers.

how the hell are you hitting 7250??? mine wont go over 7k, i know i have heard ppl with standalones raising it to 7300.

[greasemonkey524]

I thought the MSP's were electronically governed at 131mph?

[Boosted_Speed]

i got a question the governer on the car is there any way to take it off?? becouse i know i took it off a 240sx it has a tranny sensor and a wire from the ecu and all i did was cut the wire and unplug the sensor but idk if the msp might be the same

[njaremka]

why? there's no real need to be driving that fast, especially in an MSP

[nvmsp]

top speed is defintiely not 131mph. When I was stock I went 134-135mph and still had room to go on the highway. Not much more though.

[Boosted_Speed]

lol i know but i jus like fast. my friend with an srt-4 i topped out his car yesterday doin 165

[Boosted_Speed]

could a standalone change that???

[BOOSTR]

Better get it out of your system before Oct 1 2008 when HB137 becomes effective. Vehicle confiscation, fines and mandatory jail time are what is waiting for you if your caught then going 30 mph over. Right now you can be arrested for going 20+ mph over. All depends on the attitude of who pulls you over.

I'm not telling you what you should or shouldn't do, just pointing out how Florida treats excessive speed violations.

[Boosted_Speed]

nevermind lol i want to keep my car not get it impounded

There is not a governor. Just fuel cut at 7200rpms.

[magnumP5]

Awesome post Rogue - exactly what I was talking about.

Fatti, how much boost are you running? You may actually be hitting fuel cut before rev-limit. I know on some cold days, even when fully warmed up, it'll cut out on me lower. The last time I was out tuning in March (it was still pretty cold) I couldn't get the car over 6500 RPM.

Also, according to my AFC, my tach display is off by about 200 RPM (tach reads higher). I don't know if this is just factory inaccuracy or if it's because I have an MSP cluster on a P5. They have different stock wheelsizes so is it possible the speedo/tach is off due to different stepper motors?

EDIT: just because people keep asking. THERE IS NO SPEED GOVERNOR ON THESE CARS!

Doubtful...but it may depend on whether or not the p5 has ABS.

MSP's read the speed using the ABS sensors, non-ABS protege's read speed by a gear on the differential.

[Ricktalife]

i got up to about 100 in my old mp3 lol. i had plenty of gear left but didnt want to risk it.

[D-rock240]

Thanks for that info, I was just wondering why my speedo was 3 miles off with the MSP wheels yesterday. I figured the MSPs read the speed differently but hadn't searched yet.

[blaineog]

I topped my 2003.5MSP at 135 mph, and left it there for over 1min, on the speed governor (speed cut), this is well below the rev limit in 5th. Here in Jamaica the traffic laws aren't as harsh.

Im running a lil over 10psi and i know that i have it a lil more rich towards the end just to keep a lil more safe for the motor so maybe im hitting fuel cut.

I also have heard alot about the stock tach being off, i have a stewart warner tach that i go by and it reads the same numbers as the AFC so i go by that most of time, and the AFC recomonds u using there tach too.

[Prodigy]

No prob.

Different wheels? Larger diameter wheels(tires) will throw off the speedo reading.

[fr0st]

hit 220 KM/H mid-day summer heat....was at 5500-6000 in 5th so probably could have hit higher....but would never do that again on a road....


certainly not with the new Qc laws eh ?

[D-rock240]

Well my car started out with 15's, but when I put on the 16" P5/ES wheels it was only off .5 of a mile. I went by a speed reader last night and it was saying 63 while my speedo read 60. Good thing I noticed before driving through a speed trap :)

[magnumP5]

Yeah, I've got ABS. However, the P5 and MSPs have different overall wheel sizes so I just didn't know if the stepper motor in the cluster is calibrated differently (you know, 3000 RPM in P5 tires would be slower than 3000 RPM in MSP tires).

[Rogue]

the stepper motor would be the same from protege to protege

[SleepyMSP]

certainly not with the new Qc laws eh ?

no way in hell would I do that now...sheesh...but again still glad I don't live in Ontario right now

[magnumP5]

the stepper motor would be the same from protege to protege
Interesting... then where is the tach output controlled as the two have different size tire/wheel combinations. I'm just saying, ever since I installed my MSP cluster over a year ago the RPM reading has been on average 100-200 RPM higher.

[dukemoreau]

i went over 140MPH while running agains my buddies SRT-4

all stock

[protegerider]

when i was all stock i did 130-135, it fluctuated around there. havent topped it out since, speed traps are poping up everywhere in my area.

[ForceFed]

I thought the MSP's were electronically governed at 131mph?
They are governened somehow as At about 135'ish...Give or take..I either hit fuel cut...or the limiter..I cant remember which....its been years since I did this... and they simply run out of steam up there as well.

top speed is defintiely not 131mph. When I was stock I went 134-135mph and still had room to go on the highway. Not much more though.It is right around here that they are done...I would like to see this guys 165 in this car...I dont believe it....Modded or not.
Hell..It hard for me to hit 155 on my Friggin Bike...Let alone an MSP.

I am not sure...there is something that stops them.

Yes Jon...Factory inaccuracy is rampant in factory Tachs.

And Your speedometer is surely to be off with a different sized tire/wheel combo.

There is one one way to correct it the right way...by adding a Speedometer calibrator....which I know most people..99.9% have not done...nor do they even know whare to look for these items.

[ForceFed]

i went over 140MPH while running agains my buddies SRT-4

all stock
No you didn't.

What it reads...and what you are actually doing....are two totally different things.

It may read 140...but you may only be doing 125....so relying on the factory speedo as your form of speed verification would give you a false picture.

This is the same reason why some people get different reading sto what they think top speed is.

GPS is the easiest and most affordable way to calculate your real time speed.

If you do not have a SPeedo Calibrator on your car..then your SPeedometer is off, and can be off 10%+ even on a stock car.

Hell ..tire wear can and will play a part in speedometer inaccuaracies as well.
We se this a lot in motorcycle applications and most of the public and typical drivers dont even think to account for the circumferance difference of a new tire vs. a worn out one which can vary greatly.

[HondaNoMore]

on cars like the MSP with "low profile" tires, the difference between a new tire and a completely bald tire is minimal, maybe 1 MPH. figure a new tire starts at 11/32" tops, and completely bald (which no one should ever be topping their car out on) 0/32". the extra 1/3 of an inch is not going to play a noticable role in your speedo being off. i do agree that most people's speedometers are inaccurate, however, i don't think that a new tire vs. a old tire will play a huge difference.

[ForceFed]

^^ you would be surprised...a 1/3'' difference inheight is a lot more on the circumference of a tire.

Trust me..it does play a role...But the fact that the Factory Speedo is off pretty much when it rolls off the assembly line plays more of a role than anything.

EDIT..and BTW...if you were to ahve a tire that measure 11/32 new...and its down to 0/32 or bald..you would have lost 22/32....or 2/3''.

Aghh..you forgot there is tread that plays a role on the circumference of a tire on both sides....Thats a pretty big difference if you ask me.

[HondaNoMore]

ah, good point, i never even thought about doubling the tread lost. this is why having two head is better than one i suppose! all praise the forums!

[tacio25]

137 with a little bit of gear left

[speed5hornet]

my speedo told me 146, then i slowed down....i was drafting an sti ;) that helps a lot

[Nextruss]

Top speed is electronically governed at 135mph. This is enforced through fuel cut, which sucks at 135 because it broke my wastegate actuator the one time i topped her out. I was going downhill so hit 137, but yah, you don't want to hit fuel cut over 100. Not good.

[dukemoreau]

No you didn't.

Factory Flash wont change your top speed Limiter,. they sell few devices to remove this speed limiter, It´s Called Speed Cut Defender, HKS sells them as well as other company brands, i just don´t know if they will work on our MSP´s. the only known way to do it is with a Full stand alone, like a Haltech, Microtech Etc. i don´t have any Top speed limiter because I'm running a full stand alone. Haltech E6X

There is no limiter on these cars! Rev limit is 7250 RPM so unless you hit that while in 5th (which is much faster than 135 mph as has been shown previously) you had some other issue. What was the temperature outside, how many lbs of boost, etc? Chances are something else was wrong there. I cannot stress this enough though - there are no speed limiters! Chances are your wastegate actuator crapped out causing a vacuum leak which caused the cut.

[Prodigy]

NA proteges are drag-limited due to the lack of power.
FI proteges are gear-limited due to the short econo gearing.

[ItsSlow]

Would you like a video of proof? There is a speed limiter on the MSP.. Im more sure about it than my car being blue.. You can stay at WOT all day long and it will hit it everytime..

It hits ~135mph and doesnt let up until it drops below 130, which the speed will then raise back up if you're still at WOT.. You can stay at WOT the whole time and it will still hit the limiter..

[Ricktalife]

maybe the previous owner of your car put a limiter on it for their kid or something like that.

[Prodigy]

Bad spark plugs or faulty injectors. There is no speed governor, again.

[magnumP5]

Could even be fuel cut depending on how many lbs of boost you were running. On colder days I will hit fuel cut at 10 psi up around 6500 RPM almost like it was meant to be there. BTW, the fastest I've ever hit in the P5 is 110 which the very top of 4th. I won't boost more than 1 or 2 psi in 5th and that's just to pass on the highway. There's no reason to carry on beyond 110 mph. Stock, you won't hit 110 mph on a 1/4 mile track and even if you were illegally street racing you'd know who won by then as well.

The MSP 2003.5 has a speed limiter it comes in at a Speedo registered 135mph and resumes at 130mph. I have personally had a run in with it several times on our local highway. The P5 and regular ES and MP3 does not have the speed limiter.
The limiter is tied in to the fuel control, so fuel management will remove it.
Magnum P5, a protege 5 is Not a MSP, hence it has no limiter.

[greasemonkey524]

I found an article in a Car and Driver mag. (May 2003, pg.82/83) that shows the top speed of the MSP is 131 (governed). I'm about to go to work so I'll get a pic. in the morning and put it on here.

Before you start talking out of your ass too much I am running with a MSP ECU. Any fuel cut experienced by a MSP I would also experience. I'm still waiting for videos of this cut.

[mspHtown]

where do you guys typically top out your car?

i prefer neighborhoods and school zones.

[ItsSlow]

I choose rush hour traffic!

[magnumP5]

1/8 and 1/4 miles tracks - which is why I've never been faster than 110 mph in my car before.

[BOOSTR]

I-75 & The Suncoast Parkway. Smooth blacktop FTW! I know where those pesky troopers like to hide.

[greasemonkey524]

Here is the mag. article I was refering too. Maybe the 03 and 03.5 are different. It shows the top speed on the right.

[D-rock240]

It does say governed in that article. However, there have been a few articles written about the speed in magazines that has had incorrect information.

[greasemonkey524]

I believe that to be true and I have just about all the mags the MSP is in and that is the only one that says it's governed. I hate to say but I have hit that a couple times and I know it's not fuel cut or run out of gear. Even with the Unichip it still stops at that speed.

[njaremka]

from what i remember about that article, SCC was testing with a pre-production MSP.

[Jaleik]

I hit a governer at 135mph on my msp and im barely at 5600rpm then, lots of room to go.
ps alligator alley baby! top off your car all day long

not true.. i beat an SRT-4 with stage 2 upgrades before i did my car up.. 0-100, 50-100 and 35-120.. SRT-4 beat me in the 1/4 mile by less than 1/10 second

oh yea i know our cars can beat the piss out of them if we're modded right. i've seen the 500whp one that's in spain on cardomain. i'm saying from stock to stock we get our asses handed to us and so does the focus and spec so why would they compare those?

[anomaly19782009]

mine shutoff @ 135mph. 215/40/17

i used to have a spec v and was in a club with nothing but those....I had a orange '05. Mine was the odd one of the group. I did NOT have a rev limiter while all others did. Mine also got to 142mph, and that was NOT a shutoff...it just wouldn't go anymore.

But I got hit by lightning while driving in that car....got it all fixed and 2 months later I hit a deer @ 110mph ftmfl. Great luck right :D

it was before i was built and running like i am now.. i had tb exhaust, 10 psi, cai, hardpipes. but wasnt a ton of mods..

[Outlawstar98]

So we're not faster than a bolt of lightning? :eek:

no, WE ARE the bold of lightning! (gossip)

[mazda_dan]

i got mine up to 222mph and thats all i could do

[mazda_dan]

i meant 222 kmh lol

Sorry to dig up an old thread.

Fight it about all you want but my barely more than stock 2003 MSP definitely cuts fuel around 135mph well below the rev limiter. I don't need any lectures about the repercussions, just want to know the easiest/cheapest way to remove the governor.

[Mazdaspeed2oo35]

The Msp´s are gear Limited to 180-185 Mph with a redline of 7,800-8000 rpm where 5th gear is completely maxed out. The main Reason i know this for a fact is because my friend and i were testing my car out after the dyno tune on a private road here in Spain and we were running each other and i went up to 172 mph according to my Garmin Nuvi GPS at 7,600 rpm when he started to pull on me, He Have a Lamborghini Gallardo. The MSP Felt strong and i also felt with a higher redline i could of touch and who knows pass the 180 MPH mark, My redline was limited in the Haltech at 7,600 rpm at that moment.

I also have a Dyno video where you can see where the speedo needle needs to be to hit 170+ mph since i reached that speed on the rolls during dyno pull as well basically because had to do the run on 5th gear for those who wonder how the hell that fast on 4th gear...


btw this was not street racing it was done for testing purposes on a private road in Spain and by no sence im promoting street racing or people to violate the traffic laws..

Standalone engine management (Haltech, Microtech, etc.). <- That is a period, as in no question, end of story.

Once the limiter is removed see post #13 for how to calculate the maximum speed. Now need for "I did this on this road" bullshit. Can't argue with mathematics.

[fatti03msp]

in Mazdaspeed2oo35 case... yes the protege can do 180 i guess, but that is simply cause he is making alot power.

most likely an average built MSP wont be able to get to that speed, simply cause it wont have enough power push the car to that speed. On a dyno yes it could reach that speed cause its not moving, but on the road/track u would need some power to push that car to those speeds.

[Ricktalife]

Yea once you get past a top speed of say 150mph, the amount of HP you need to keep going seems to get significantly higher. I don't know shit about physics and all that, but considering the Bugatti Veyron tops out around 250mph (I think) and has a little over 1000 HP...Miguel is around 500whp or so, right? So there's a big difference in power there, but the Veyron really isn't going as fast as it could if we didn't have any factors like wind and such lol.

Like I said I don't know the technical info but it makes sense to me.

edit: I don't know why we're even worried about top speed. The MSP is plenty capable of costing you your license.

[Outlawstar98]

HP numbers dont matter people, its how the power gets to the ground and the weight and shit like that. and the bugatti has 4 turbo's, Miguel has only 1 and made it higher then any other protege owner will most likely... but theres prob. a civic out there that will beet a Bugatti in a straight line... hahaha

But Can you people refrain from taking about illegal stuff in this thread... I just read though everything and Gosh people.... haha

+1 but even a geo metro can do the same thing.

You're missing the point. I'm not putting Miguel down for ONLY reaching 500whp...(that's funny). I was using the Veyron as a benchmark for crazy top speed.

[XoX1de]

Veyron reaches speed limit is mainly caused by 1. Aerodynamic, 2. All-wheel-drive drivetrain loss. The SSC ultimate AERO is RWD therefore power goes more efficiently on the ground, less drivetrain loss. Its the current production car speed record,263mph I guess. And it seems to be spining the wheel on top gear during the speed record... ridiculous.

Thanks for the reply. I was afraid that was the answer. I would consider one of the piggybacks, but a standalone is above what I am willing to spend on this car.

[HondaEat-R]

I know i'm going to get flamed, but why are you guys driving that fast on public roads ? How many dead forum members cars do you need to see mangled to realize that it's stupid. A tire pops at 135mph, and you're fucking toast, not to mention you could take someone else's life because you had to see "top speed". Worth it ? Doubt it.

they do it on fast and the furious, so its obviously safe.

[Jspeed17]

lmao!!!

[FlyinHawaiian]

Yeah... I also disagree with the people who say theres no governor on our cars. I've had my car up to top speed a couple times and it hits a fuel cut around ~135 MPH. The car is still accelerating up until that point and has a lot more juice/gear left. My old Protege had this too, despite everyone claiming that there isn't. I know what I felt, and it sure as hell FEELS like a governor - sucks ass too

[HondaEat-R]

People need to be safer / smarter.

what? lol

HP numbers play a huge factor not saying that the lightness of a vehicle wont matter either, but like it was mentioned aerodynamics play a factor as well. All three factors come into play when trying to get to a top speed. Not to mention that a veyron is way more fully loaded than a protege.

ever hear of terminal velocity?

[anomaly19782009]

so, from reading this ancient thread, risen from the dead....a unichip, tuned can't cut the governor?

always wondered that.

I think it doesn't since is a Piggyback and not Standalone but i could be run, i know for a Fact Standalone does..

[Outlawstar98]

Any piggyback will not cut the speed limiter. Only a full standalone... Unless someone gets enough balls and $ to find someone who can Reflash the MSP ECU with upgrades and get rid of the Limiter... Doubtful.

[daltonjohnson]

1/8 and 1/4 miles tracks - which is why I've never been faster than 110 mph in my car before.

sorry i was gonna stay out of this but........

if you have never been more than 110 in your car, then how would you know that it isn't limited. there is a rev limiter in the mazdaspeed protege. a rev limiter keeps the motor from spinning too fast and coming from together. example, put it in first gear, let off the clutch and put your foot in the floor. when the tach goes to bouncing at 7000-7300 rpm, thats a rev limiter. if you get to fifth and hit a rev limiter, damn. you will be going as math has proven 160ish. what really happens is that the motor is pulling a bunch of air, the turbo gets really hot and starts losing efficiency. the fuel system attempts to compensate and cant. the maf tells the computer that the car isnt getting enough air and that the motor is in danger, so you get a fuel cut. more efficient air delivery (or a colder day) will help with the fuel cut. if you really want to know what is going on with the car, get a pyrometer, a boost gauge, and an air fuel gauge. this will tell you a bunch about the car.

my story. i stretched my car out when it was 92 degrees. when i hit 130, the pyro was at 16 and climbing. as i stayed in it, boost slowly went from 7 to 3. at 146 according to gps, the car shut down and i let it. i slowly dropped back to 65 or so. i ran it again a month later and it was 67 degrees. the turbo heated up about the same, but the boost only dropped about 2 pounds this time instead of 4 and i got to 148.

bethat said, i will never go that damn fast in that car again. it will do it, but its a little tall and a little narrow to go that fast. i will stick to less than 120......

[magnumP5]

^^^ You seriously replied to that after all this time? I mean, seriously? Some of what you said in your post is just flat-out wrong (fuel system compensating for turbocharger efficiency, wtf!?)1 Let me try to point out some of the reasons why you are an ass:

1. You're an idiot for going that fast in the first place.
2. We're talking about speed governors, not rev-limiters (two different things).
3. While fuel cut is MAF-related (voltage o/max), rev-limiters and governors are pre-programmed for RPM/speed
4. Don't even start to "try" to educate me on how this automobile works - I've been more ways around a Protege than you can imagine.
5. You replied to a comment I made God knows how long ago (forum n00b?).
4. I OWNED a Protege5 - different ECU
5. I don't even own the damn thing anymore so I couldn't give a fuck what you have to say

Anything else?
