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

143.3 mph on my gps before it would shutdown.

142.8 for me.

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!

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.

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???
