465whp should be attainable with upgraded turbos.

I'm curious how a procede v3 would do against the alpina b3...

[rismo]

The car seems to be capable to speed above 300 km/h (which should be divided by 1.6 to get miles I believe)

I have a GPS measured 304 km/h set on an empty part of the German highway and had still some revs left.

The european speed display goes to 280km/h max, the initial test was to actually find out what would happen to it, it still seems to function normal afterwards, then we decided to push it all the way.

This was with a procede v3, 6AT, open air filters, M suspension and EBC brakes.

Car was handling this quite well. felt not that bad or instable.

[stressdoc]

305.6 kph = 190 mph. If your GPS is accurate, then 200 mph / 322 kph might be possible with appropriate gearing and aerodynamics.

That is very exclusive company.

[cocoturkey]

final drive ratio = 3.08
6th gear ratio = 0.87
rear tire specs = 225 30 19
red lline = 7000 rpm

TOP SPEED = 7000 / 0.87 / 3.08 * (225*(30/100)*2+19*2.54*10)/1000)*3.14159) *60 /1000 = 313 km/h = 194.48 mph



sorry...i wrote it wrong!!! it's now correct.

Wouldn't the theoretical top speed be attained in 6th gear, not 5th? Just wondering because you listed the 5th gear ratio. Though it doesn't seem to affect the equation. The rear tire spec should be 265/30/19, which would equate to a top speed of 315.9kph = 195.8mph. Working backwards, we would need to increase redline to 7147rpm to hit 200mph (and be making peak power at that rpm).

We've definitely seen numerous Supras eclipse the 200mph mark. So, who is going to be the first 335i to do it???

I saw some guy's street legal turbo mustang hit 211 mph in the 1/4 mile.... i still think my 335 is faster

I bet that the stock car could still go at least 280-290km/h without limiter so after the procede instalation this could be around 310km/h.

(anyone knows to convert in mph ??)

Multiply figure in kmh by 5/8 to get mph (or divide by 1.6)

[badass335]

I took my procede car up to just past the 280km/h and it felt like it could have push a little more! At 289km/h would equal 180mph so I'd say very possible though not much higher. I'm auto as well!

[Dr_Dirt]

Just make sure that your car doesn't go over a small hill while at 150mph+. When I was cruising the autobahn some years ago, a car hit a tree. Now I know that doesn't sound all that strange except for the fact that the car had left the ground, it was 30 ft off the ground in the high branches.

Just some food for thought, some cars become frisbees at high speeds, here are some takeoff speeds for some familiar aircraft...

Aircraft Takeoff Weight Takeoff Speed
Boeing 737 100,000 lb
45,360 kg 150 mph
250 km/h
130 kts
Boeing 757 240,000 lb
108,860 kg 160 mph
260 km/h

Airbus A320 155,000 lb
70,305 kg 170 mph

Nice info guys, especially Dr Dirt ;-)

We will absolutly take care not to lift off!!

This spring we plan to perform another run. Hopefully including a turbo and intercooler upgrade, and then hopefully will can go really to the limits.

What about aerodynamics? As far as I understood from the experts, each car has a certain aero dynamics "wall" / limit.
After that limit men need to add a lot of extra power to just get a tiny bit further in top speed.

Any of you with some more explaination around this topic?

Lol whatever you say speed racer......

A Dinan Stage 2, otherwise stock, 335i will hit 159 on the speedo with ease. I'm not sure what 159 on the speedo is in actual MPH.

I know this thread is for the V3, but thought I would share this anyway.

[iwant335i]

chipped 535d did 295kmh theres a photo this page something like topspeed.com or else

[stressdoc]

When I started this thread, long, long ago, I didn't mean for the question of top speed to be restricted to Proceed. So Dinan et al (tunes with speed limiter removal) are more than welcome to post up results.

It is interesting to watch the max speed increase with software advances. I used to think that 280kph was a stonewall. Now we have 335s going 300kph+ Amazing.

[chavoush]

For what its worth, i just drove from san antonio tx to Los Angeles so had plenty of highway time to el paso to test things out. I hit topspeed on speedo at 158mph STOCK, with 335i sports package. No mods, lol, didn't want to test the jb3 i just got on a 1300 mile trek. FYI, the car definitely doesn't seem as stable once u hit about 140mph compared to my 350z which I took up to 155 once (speed limiter). Just my 0.02!

[mike281]

^no way u hit 158 stock. The car has a speed limitter in it.

[vase330]

Yeah, anyone who tried this on ED (I suspect a Majority of posters on here who did ED) will attest to the fact that hitting the speed limiter stock, was easy on the autobahn. A buddy doubted the 335 was capable of much more, but he doubted until I showed him my unlimited video of 181 mph. The car finishes the speedometer in 5th, shifts into 6th, RPMs drop some, then start climbing as the car goes faster and faster. The needle is stopped at 160 the whole time, but if you have GPS, you can see your eyes are not lying to you, you are actually going faster and faster.

Past 150mph, things get very dicey, and anyone who tells you the car is stable and calm is definitely not being very honest, or more likely did not pay enough attention to what the car was doing at those speeds. First of all, the wind noise quadruples with every 10mph faster you go. (Ok, maybe its coupe thing ) The car sounds more sport bike than car at those speeds, and if you are not on an absolutely smooth road, the car seems to start almost dancing on its feet. It feels like you are floating over a million tiny potholes where the wheels merely tap the surface. You also become very aware of the fact that one thing goes wrong, and well I doubt you will be around to tell the tale. Oh, try using the brakes to haul the car down to sane speeds and you get an idea. It just doesn't seem to slowdown for an eternity.

I almost nailed another car on my ED going about 150mph. I hit the brakes hard, stood on the damn thing, and the car slowly slowed down. It was very linear though and does not pull to any side even though you can feel the pedal pulsing like crazy.

Didn't you see the episode of Top Gear running the Veyron to top speed?

Said it takes 270hp to get to 155mph...and another 730hp to get to 253.

Faster you go...the more power it takes...exponential equation (but don't have it handy).

[vase330]

I believe you can google the whole episode and watch it. Yeah that was really something. Did you see the MPG when going at top speed? Burns through half a tank so fast! I think they said from a stand still, with a full tank, you only have enough gas to reach the max speed and hold it there for maybe two minutes? Not sure, its been a while since I saw that episode, but yeah that thing is definitely ridiculously fast. Any of us think the 335 is fast after seeing that, you just want to laugh at your perception of fast. Its all relative.

[rismo]

Hi Vase,

The sound after 220 / 250 km/h is indeed heavily increasing, but regarding the stability, migth it be that the M sport suspension helps out to keep the car stable?

I also noticed that when I drive the car with all electronics turned off, it's quite a bit less stable, but still on the complete flat highway we drove on, the 300km/h was really go to do!

FWIW, when the speedometer shows 155mph, the actual speed is more like 145mph. Not that that isn't slow, of course.
