True Top Speed Of A Stock E36 M3??

[M5IAN]

Ok I have driven a tuned M3 and gone 150 (not topped out) and i have driven a stock one up to 137 (governd) mph several times but what is the TRUE EXACT top speed of a bone stock E36 M3 without a govonor??? OBD2

Only mods i have is cold air intake, catback, and software. Now once in a buzzed rage on a 9 mile bridge, my friend and i buried the needle and the tach was all but buried as well. Having the software allows your car to run 500 rpms past stock restriction as well as lowering the ration of rpms to speed by about roughly 5-10 mph depending on speed. I would assume that not having the software i still woulda been able to bury the tach minus 10 mph from the software, minus another 10 from the tach restriction which would put ya right around 140-145. Plus you gotta remember that the faster you go the less accurate you speedo becomes. So in conlcusion you could "really" do about 135-140. Hope I didnt confuse ya.

BTW, I used to have an R6, and would barely crouch at 120 and not even blink at 140. I dont however recommend going that fast in a car, as I it felt alot faster at those speeds compared to my bike. Honestly, I slowed down not cuz I buried the dash, but cuz I almost $hit my pants. Have a good one

umm minus software you can't go past 130

edit: slightly drunk didnt read your whole post...but i would say without a governor but still stock software etc. i would say about 150 because the power is still about the same. i have done it in my previous 325 so im sure a stock m3 could do it without the governor.

when i said minus 10 from the software, i was talkin in theory (without a governor). btw, E36 M3's are governed at 140. also i had my car dynoed as i put each mod on. the shark injector increased hp from 209 to 217 at the rear wheel. id say isnt the quite the same as stock. not to mention with everything i did, peak hp at 7300 was 238 at the rear. that definintely isnt the same. in response to what u think top speed is, we pretty much agree. but what the speedo says isnt accurate. give or take a couple mph your lookin at a 10 mph error margin. not tryin to be argumentative but sounds pretty far fetched going 150 in a 325. i wouldnt bet the farm im right, just stating my opinion.

i had 3 witnesses in my car when my car was still a 325 that witnessed me burying the needle into the dash...granted it took a long time but my 325 still hit 150. and e36 m3's are not governed at 140...its 130. my friend owned one...my uncle has owned one...the limiter kicks in at 130. i know from experience as well i raced a stock m3 and he couldnt go past 130 so i was toying with him and raced him with cruise control

What is the HP rating?

I drove once 145 mph in my stock 325 (192 HP) and I can prove I hit the 141 with this car (see my website, also more BMW stuff on it)

The M3 hits the 160 mph for sure.

[///M Dream]

im not sure about 160 but me and my friend went 130 and there was plenty of space to go faster.

[///M Dream]

stock e36 m3 has 240hp im not sure about the tq figures

You can count your topspeed this way:

Drive exactly 60 mph and watch your rpm's (you have to drive in the highest gear). E.g. 60 mph in 5th gear @ 2500 rpm.

Now watch your car manual for the rpm where it have the highest HP output. I'll take 7000 rpm for example.

The speed that your car can hit is as following: 60 * 7000 / 2500 = 168 mph.

Your car can hit the 168 mph when there's no governor in this example. Fill in other values and count the topspeed of your own car!

So... I have a Honda that pulls 1800 in 4th at 60. Lets do the math. 60 * 5800 / 1800 = 193.3 mph. This four banger starts hesitating about 105 mph. Not a good way to guess. The higher the MPH the higher friction all over. If anyone can get a stock M3 over 150 call Guiness... Cause there is a big hill somewhere.

Some major miscalculations, for once you're not taking into effect is aerodynamic drag (which is alot).

A cars speed can't be calculated with linear interpolation. I hope you're not an engineer

Euro M3 top speed:

Stock M3 3,2L is limited around 260 km/h.

Remove the limiter and it goes 274 km/h. This is with the 3,23:1 final drive.

Change the final drive and install a 3,64:1 and add a muffler for 3-5 hp and sound: 295 km/h with the new final drive. The reason why the car goes faster with almost the same power is that because the 3,64:1 final drive enables to finish the 6th gear.

Yes I am and I made no mistakes. When you're driving 70 mph @ 2500 rpm and rev up to 5000 the engine rotates twice as much in the same time. The wheels rotate twice as well, so the speed is gonna be up to 140 mph. This is only true with a manual transmission because automatics generate slip.
And yes, the cars speed is linear (while in same gear and it's no auto).

I hope you're not an engineer

4th is highest gear? What do you mean by 5800 rpm, redline or rpm where the engine generates the highest HP rating?

What about wind resistant you idiot. Take your hands outside your window when travelling 100 miles/hr you will see how hard the wind pushs your hand. What do you think it, that does'nt greatly effect your car. Look at the total surface area of your car hitting the wind.
