Top speed of the MSP

[Drumfreak]

Just cuz I'm a risk taker sometimes I topped out my Mazdaspeed cuz I was curious. With one other person in the car I got it up to 137 MPH. When I hit 136 the engine started to shut down. Probably just the ECU cutting the fuel. Anyone else had this same experience. My friend didn't believe I could crest 130. Ha ha I showed him. I would suggest on not doing this cuz it's super dangerous. I inspected my car before running i.e. tire psi, lights, temp, coolant, oil. Plus it's very illegal and how in the hell do you explain 137 mph to a cop let alone a judge when your ass is in court. The car feels very smooth over 130 surprisingly. In addition it didn't take very long to get up there. And this was with a fat chick in the car. I wasn't scared the whole time. Cuz she is just a friend. Anyways, that's how fast these go so need to try just use me as an example. But I would love to hear similar stories.

[chillinmcmillan]

I had mine up to 220...........km/h that is, not sure what that is in mph, that would suck in court though....you are charged with going 220 in a 100 zone how do you plead? FUCKED!

[Aaron]

I did 138mph handled really good.

[Drumfreak]

I did 138mph handled really good.
Did your car start shutting down?

[Aaron]

no suprisingly and I think it had a little more.

[slug420]

I have had mine up to 70....it felt like it could go a little more too but i didnt want to push it..

[Aaron]

yeah 70 is pretty scary shiaaatttt.

[wicked]

137 is all you can do.
trust me I've been there lots,and lots of times.

the car may feel stable at that speed,but trust me,it's not.

I slid mine across 3 lanes of highway

[slug420]

jackass...

[murph1379]

137 is all you can do.

That's really stupid.


I slid mine across 3 lanes of highwayAnd that's why.

People like you make my insurance go up!

[wicked]

That's really stupid.

And that's why.

People like you make my insurance go up!
people like me make my insurance go up!


relax the highway was empty,and had six lanes.
I may have been sliding,but it was controlled.

if any car was going to be wrecked it would have only been my own.

[grcuadros]

fastest i went was 134...i was too scared to keep the pedal down. it took forever to get that high.

[thunder]

I had mine up to 220...........km/h that is, not sure what that is in mph, that would suck in court though....you are charged with going 220 in a 100 zone how do you plead? FUCKED!

That is if they can catch up with you! lol Here in QC they quit chasing once they reach 160 km/h (and even before). A lawyer even said that if they start chasing you, just go up to 200 km/h!! (on the freeway of course)

How did you do that? How sharp was the turn?

[Puckpimp71]

Are MSPs drag limited?

[SP33D]

i went 134mph.. pretty stupid thing to do tho

I would imagine that they would at least get your tag number before letting you go. (shrug)

[Wiggles422]

Are MSPs drag limited?

governed I believe

[lgagno1]

governed I believe
Nope, only drag limited. This has been discussed to no end.

[Wiggles422]

i sit corrected

[silverturbozoom]

had mine beyond the 140 marker, i say 145ish but still hit a fuel cut, felt like hittin a wall....speed only kills time

lol
maybe thats why they took my license for a 89 in a 55.....hmm

[Heathen23]

The car is gear limited.

Try a search on this matter there is definitely a ton of material on this topic. Nothing wrong with bumping an old thread either (thumb)

[TheJohnny]

I went beyond the 140 mark like many others.. downhill in death valley.. what a place to crash and burn. We were on a group drive with like 20+ cars... it was insane to see that many cars going that fast....

[project_msp]

I've hit 130 with a cut once... second try I hit 135 with no cut (other than me taking my foot of the throttle)... MSP's are so weird :)

[turbo speedy]

the fastest i have gone was 138 mph then the car shut down

[03MSP]

130 for me, it took a long time because I was only at about 1/3 throttle in 5th (I'm scared to boost in 5th gear, so I kept it at 0). At 130 I shut it down, didn't want to go anymore; btw this was at like 3:00-4:00 in the morning on an empty Iowa highway. I probably won't be doing it ever again because I consider myself lucky that I didn't get caught.

[505zoom]

Stock: 135... cut

Intake, exhaust, FMIC: 137... cut

Haven't tried it since way back then, but I had RPM's left, and it hit a cut, so I say again that the car is not limited by drag or gearing. It is a cut that is probably based on airflow just like the cut you will hit when boosting too much.

Just my .02

(mswerd) if it was drag limited you wouldn't hit a cut, you'd just stop accelerating.

[Bass Addict]

I'm either a pussy, or I'm just really smart...but I don't see myself going over 100 on an interstate. I dunno, I know what my car can do..I trust you guys, but I'm sure as hell not going to do it. lol

[Metal MP5]

i was arrested by an off duty cop last weekend. i think i cut him off doing 130 oh the highway (kmh) he got behind me and started flashing his high-beems at me ... after like 2mins i got fed up so i sped up, started passing cars. went up to maybe 150 ... he was still there doing the same thing. I got scared. Who knows what this guy wants. With all that road rage crap we hear about on tv n stuff, i didnt wana take any chances. so i really started speeding, passing cars left and right ... got up to ~200 then slowed down. he caught up and kept flashing his fucking lights. he then changed lane and started coming up left to me so i jammed the brakes, got behind him and started doing the same thing.

that's when i saw his arm out of the window with a badge (hand)

after a long talk on the side of the highway (maybe 5mins) he left. i didnt get anything.

[Newf]

I'd say that qualifies as a close call.

[azian6er]

I'd say that qualifies as a close call.


understatement of the WORLD

[Metal MP5]

yea i know. but i dont think an off duty cop can give you a ticket. He did say that he called for backup to catch my friend ... but by then, he was a few kms ahead of us. I still called him as soon as the cop left to tell him to get off the highway cuz while i was talking with the cop, i saw 3 cop cars pass at like 180 next to us.

The cop said that if i hadnt stopped within 30sec (he had been following me for like 2min30) he wouldve had to call for a backup helicopter to follow me.

I coulda been on tha newz !

EDIT: what scared me the most though is that i really thought the guy wanted to run me off the road or shoot me, so in a way, i felt i was forced to drive that fast ... at 7pm ! the highway isnt exactly empty at that time of the day. I don't mind driving fast at night when there's nobody around, but that was just too crazy. This wasnt something i planned to test, but our car does handle pretty well at 160 ~ 200kmh zigzagging in light traffic.

You have got to be the dumbest person I've read about on this forum. Seriously. I really hope you're being sarcastic or lying.

[jurgs01]

LOL. Running from the cops swerving through traffic? Been watching too many movies lately? Anyway, the MSP can get up above 140. When I was traveling through North Dakota (when I first got my car), and there was straightaways for ever. I tested my completely stock car and It went over 140. It wasn't accelerating very fast after 130 though.

[Metal MP5]

i wasnt running away from a cop but more from an SUV that was up my bumper flashing his high beams at me

tease: i dont really care what people on the internet think about me. but you go tell that to the people that died here last year because of similar road rage incidents. i rather drive faster and pass 4~5 cars at high speed than being hit by some crazy SUV driving guy or being shot.

People have been shot here on the highway before. ok that was a cop, but i didnt know until after i let him pass in front of me, which he fully understood while we were talking and why he let me go.

don't judge other people that fast

[stevesMSP]

Just cuz I'm a risk taker sometimes I topped out my Mazdaspeed cuz I was curious. With one other person in the car I got it up to 137 MPH. When I hit 136 the engine started to shut down.

[Brian MP5T]

230 Km/h is pretty much where the car hits 6300 RPM.

137 is all the ECU lets you do!

[Metal MP5]

i like how he says im the dumbest person ever cuz i drove mine up to 120mph to avoid a possible collision, and everybody is bragging bout how they did 137 and he doesnt say anything

maybe cuz im canadian

and like wicked said, the ECU will not let you do more than 137 ... if you did, you either modified the signal or your speedometer is fucked. if its none of the above ... can we swap ECU ? =)

[mspHtown]

He was jus distracted by ur avatar (humpleg)

[jurgs01]

137 is all the ECU lets you do!
I watched mine go past 140 (not much). I don't think my speedo is wrong, and it was a little bit downhill but that shouldn't matter if it is the ECU that cuts your acceleration.

[Metal MP5]

ecu cuts your throttle ... it wont put the brakes on if the car starts accelerating because you're going downhill

one thing i noticed though with my apexi avc-r is that my speedo is off by about 4kmh ... for exemple, when my apexi says i'm doing 120kmh my speedo shows ~123 - 124

I've heard that most cars are like that so that you are always driving a few kmh (or mph) slower than you think. Same thing with the tachometer .. i think it always shows as reving higher than it actually is

It's probably diferen in every situation, I have removed the Rev limit and Speed cut. But the tranny still limits your speed because of the "Red line"


You want fast, get a GT-1, (hand) Sell the MSP!!

[Metal MP5]

ok so the tranny limits your speed because of the redline,

one thing id like to know .... is the RPM the same on a stock MSP doing 120 and a 200whp MSP ?

[Brian MP5T]

one thing id like to know .... is the RPM the same on a stock MSP doing 120 and a 200whp MSP ?
Well, Yes. Why would it be diferent. The MSP has the same pistons and rods as the normal 3rd Gen Protege family. It has a better clutch and an LSD, so why do you think the top speed would change if you had more HP?? Makes no sense...

(poke)

[Heathen23]

ok so the tranny limits your speed because of the redline,


Thank you Metal for posting the reality. It's gear limited. The car doesn't cut fuel, it just stops increasing speed.

[laracroft]

110 and I shiat bricks ... lol
Also had a quick go with a Lt. I work with. He of course had a crown vic. A lot of the other officers at my dept like my speed, and that's saying alot. It's cool to get respect from my car like that, especially when so many of them have domestics. I get asked about mods for THEIR cars all the time. Some visit the ******** site and surf a bit. (and no, dont worry guys... they are not looking for people to ticket or put away.. lol)

[Metal MP5]

(poke)
i dont know. cuz the engine just works harder and would be able to go faster at a given rpm. i was just wondering.

for exemple, a Protege5 (or any 3rd gen protege i think) can't go over 195 stock. I've tried it ... the car cant accellerate past 190~195, you're in the redline at that point

howcome an MSP with same tranny (i think) can do 220 ? I think the engine's power has to do with your top speed in a way, not just the tranny

[Metal MP5]

Thank you Metal for posting the reality. It's gear limited. The car doesn't cut fuel, it just stops increasing speed.
it does not just stop accellerating. it cuts for about a second or two. Same thing as on my friend's GM, it cuts at 170kmh, drops to 160, then starts going again.

our car cuts at 220, drop down 5 or 10kmh, then starts going again. i dont think that's tranny related.

mine is like that

[protege02]

mazdaspeed isn't that much faster than my basically stock 02 es(only engine mod mazdaspeed axelback). 128mph is where it stopped at like 5200rpm which means i could reach ur 138mph with some kinda ecu changes. it was done at the michellin track in south carolina so controlled environment. but i did do 118mph on georgia 400 at 3am coming home one night. (hand) i wouldn't do that anymore though.

[slug420]

how are we not mentioning the 1 determining factor here? I have a lift kit on my MSP with 32" diameter tires. my top speed is around 200mph.

tranny doesnt limit your top speed, engine doesnt lmiit it....those limit maximum times your wheel will spin ever X. But as you increase the diameter of your wheel, you cover more ground in X, thus going faster.

Its all about wheel diameter........suckers.

[mazdaspeedpower]

chillinmcmillan, I'm using your words in my sig

[Metal MP5]

haha its true but your car will not know how fast you are really going. It will cut you off once you get to 137mph, but in reality, you'd probably be doing 250 or something

check this out: http://www.miata.net/garage/tirecalc.html

For exemple, MSP tires are 215/45-18, my winter tires are 195/55-15. The site does all the calculations for you. In my case, it says "Speedometer reading with non-stock tire is 4.8% too fast. When your speedo read 60mph, you are actually traveling at 57.1mph"

[wicked]

first off the question is refering to the MSP it says nothing of modded MSP,or MSP on dubs,just the top speed of a stock MSP.

[Brian MP5T]

i dont know. cuz the engine just works harder and would be able to go faster at a given rpm. i was just wondering...

Your speed is determined by the radius of the tire and the rotational speed of the tire. The tire speed is based on the speed of the shafts and the shafts spin the speed of the Diff. Depending on what gear you are in (Lets say 5th) a car with 100 Hp and a car with 6000Hp will both top out at the same speed if the tranny gearing is the same... "Your redline" will determine how fast you can go. Once you hit it, you must stop or your engine will be destroyed quickly. Unless you change the redline or the gearing in the car, no matter how many more HP you think your "Mods" have givien you, the car will simply not go any faster.

...It will however get to the top speed faster.

.........this is were your final drive comes into play.

something that has like a 4.5to1 will accelarate quik,but have a low top speed
but if you have a 2to 1 then you will accelarate slowly,but have a very high top speed.


there are lots of things you can argue about one this thread,but the origanal question just asked what the MSP's top speed is from the factory.

I understand, I was actually blown away that this guy would think that putting on a CAI and a boost controller would change the gear ratios in his car...


(hand)

[tritonheat1]

The MSP has a Final Drive Ratio of 4:1. Which is good, the Stock tranny and Ecu will only let it go to 143mph if possible "No matter if the car is a 10sec 1/4mile car. It'll be limited to 143mph, unless if you change the final drive ratio and Tranny!!!! Other than that "that's the Stock MSP's capable, Top speed" if you can get there. For an Example: my friend had a (Completely stock CRX) topped out at 110-115mph. Got a whole new motor, LS/VTEC with bolt on's with GS-R tranny!!! He pegged the needle at 120mph, but for sure was going faster than that!!!!!

[slug420]

i have official documentation form Mazda of Brazil right here that states the top speeds of all mazdas in stock form.

Looks like the orange paint allows spicy mazdaspeeds to go 153 whereas the other colors top out at 136.

So sorry guys, you are all wrong. Ill scan the document later. Its official. Trust me. It makes sense too when you think about it. I mean the solar voltaic mass of the amperes in the photons from the rays are combustulated in the orange paint which connects to the flywheel.

you're all a bunch of idiots.

WHY NOT JUST BUY A FAST CAR?(poke)

Ok guys, a little secret, you can disable the REV limiter and the Speed limit/fuel cut at the dealer. Just get the nice lads and lasses at your local Mazda to plug in and disable the settings. I did just that and the car doesn't stop until I stop it at the redline in 5th.

[H-Town Speed]

Mazda Type-F5M Tranny Gear Ratios:
1st - 3.307
2nd - 1.842
3rd - 1.310
4th - 0.970
5th - 0.755
Reverse - 3.166
Final - 4.105

Mustang T-45 Tranny Gear Ratios:
1st - 3.37
2nd - 1.99
3rd - 1.33
4th - 1.00
5th - 0.67

Now bear with me here. You can use this ( http://www.corral.net/tech/gearcalc.html ) rpm/speed/gear ratio calculator to determine top speed at what rpm with a certain final drive ratio and with a certain tire size. This calculator is geared for use with mustangs and you can't type in a specific tranny gear ratio so just select the T-45 5th gear(0.67).

Now if you get 0.755(our 5th gear) and multiply it by our Final drive ratio(4.105), you get 3.099. Next divide this number by the Mustang's 5th gear ratio(0.67) and you get 4.626. If you multiply 0.67 times 4.626 it also equals 3.099. So where the calculator asks for rear end gear just type in 4.626. Now punch in the rest of your numbers and have fun with it. This caclulator is just and approximation and doesn't take into account several factors such as tire wear and speedometer error, etc.

According to this calculator at 6500 rpms in 5th gear the MSP has a theoretical top speed of approximately 153.59 mph. At 6000 rpms in 5th it has a theoretical top speed of about 141.77 mph. 137 mph would be right at around 5800 rpm's.

[Metal MP5]

137 mph would be right at around 5800 rpm's.
that seems about right
