Quickest and Fastest Stock 335s in 1/4mi?

We certainly have some good numbers on dragtimes but does anyone have all of those handy to present in one table/post for bone stock 335s?

I'm interested to see what the fastest a stock 335i and 335xi, 6mt and 6AT can do WITHOUT RACE GAS on the track, real conditions. My guess is low 13s but under ideal conditions maybe someone squeaked out a 12.99?

TIA

I did a 13.31 @ 104.xx with a 1.9x 60', completely stock (tires, rims, everything) on pump gas. Took a lot of practice though. MT, too.

the 13.31 was not my 60' too, I had a 60' that was 2-3 hundredths better. So, in theory, a 13.2x is possible.

tips for launching an MT? What RPM's do you shift? Do you shift into 4th before the finish?

hold revs around 2800-3000, ride the clutch on the launch (I would let my clutch out prob about 1/4-1/3 of the way to start moving then let it out pretty quickly from there). Shifted close to redline for 2nd and 3rd. I would finish the 1/4 in 3rd but would be pretty close to redline.

Nice times- that's movin!

I'm hoping to clock in around that with a better 60ft (I have an XI) but slower mph from the extra 250lbs.

The weather in CT is pretty cool now- in the 50s and 60s. Ideal drag racing weather!

Man some of you guys are doing better stock than I am with a V3. My best stock time when it had 1200 miles on it:

60' 2.171
1/4 13.452@104.59mph

Tuning the car is so cheap why would anyone bother to race stock?

Before I tune my car

335xi
6mt

Everything stock:

60 feets: 1.921
1/8: 8.565 at 83.55 mph
1/4: 13.312 at 103.81 mph

A+

I would think the 335xi would get some of the best stock (and tuned) 1320 times. Given that somebody is willing to launch that sucker hard out of the hole and pull in a low 1.8x or high 1.7x 60' and powershift the car, I could see a 12.9x for sure.

low 1.8xx or high 1.7xx ...not easy with stock power and stock tire. And I have try many time and impossible for me.

Now I run 1.75 on 60 feets..but tuned.

my opinion

I don't believe 12.9's would be possible still.

Keep in mind, though the xi can launch hard, it has an additional 250 lbs to haul around, AND has additional drivetrain losses (and slightly worse aerodynamics too).

So where a best possible stock 335i time of say 13.2x @ 105+ mph might be possible, the 335xi will lose most of what it gained in the first 1/8th mile from it's launch in the last 1/8th mile because of it's weight and extra drivetrain losses.

At a VERY fast track with nice cold upper 40's temps with DA's below sea level I think both the 335i and 335xi are capable of low 13.2's but where the 335i might have trap speeds in the 105 mph range, the 335xi will be in the 103-104 mph range.

In an 1/8th mile track I'd give the xi a .2-.3 second advantage

I think the 13.3's that some people (and a magazine too I believe) have gotten are going to be in the top 10% of times. And even that requires a very good track with good weather conditions and a car that runs on the strong side of average (and a very good driver if it's a manual).

I'd say for most people at most tracks with decent weather, or I should just say the "average" for a stock 335i would be
13.4-13.5 @ 104-105 mph (add a tenth or so for manual transmission since they are harder to launch and usually don't do as well.)

I agree with you the xi should be able to have faster 1/4 times. Even though the xi is ~200 lbs heavier it has the advantage because it can launch harder due to the better traction (4 wheels vs 1 wheel). Plus, the 60/40 split and transitioning to RWD at 100mph takes aways some of the drivetrain loss as it picks up speed. However, over 100mph I think there is a disadvantage but by this time the 1/4 mile is almost over. Just my 0.02 cents.

When I had my coupe 335i I ran a 13.63@103mph in Tucson at 3100ft altitude and totally in the middle of the summer(last year). Had I ran the car at sea level and in the winter and it would certainly put me at around 13.3@105.
If I am not mistaking the quickest I ever seen on dragtimes was a sedan auto doing 13.25 bone stock.

I think in a sea level and cold weather track you could possibly do a 12.99 wit a lot of practice.

Just a note here, it's not 4 wheels vs 1
When going straight, on a hard launch both wheels will spin on the 335i (even the ones with no e-LSD).
So it's not like the 335i's accelerate with just one wheel

As for the launching harder anyway, has anybody with a stock 335xi gotten better 0-60 times than 4.8 seconds?
The AWD is an advantage, but in reality it's not as much as people think.
Look at it this way, a stock 335xi can probably pull a best 1.8 60 foot time. The stock 335i can do a 2.0
That's about 1/2 CL
The 335xi might then pull another 1/2 shortly thereafter (because it's in the meat of the powerband sooner) putting it 1 CL in front by the 1/8th mile.
After that the power to weight advantage, the less drivetrain loss and the slightly better aerodynamics of the 335i kick in and starts to reel in the 335xi and will pass it at or just before the 1/4 mile stripe. (probably before the 1/4 mile stripe and win by 1/2 CL with a trap speed of 1-2 mph faster.

I've owned AWD cars and know their launching advantage, but also know their higher speed disadvantages.

I honestly don't think a 335xi will have any better ET's than the 335i and will have slower trap speeds too.


EVO to MR
I remember your time from Tucson.
I'd say you'd of easily of gotten a 13.3 or high 13.2's if you were at sea level and on a cool day.

Again, I think you guys are dreaming thinking a stock 335i or 335xi can get 12.9's

To give you an idea, 12.8-12.9 was the best times you could get with the 335i on PROcede v1.2 to v1.4 and on a JB2 and even JB2H

If you think a stock car could get close to those times with 40-50 less hp you are kidding yourselves, sorry.
Heck I got a 13.0 @ 107.8 mph as one of the very first tuned 335i track times ever posted on the very first batch of the original PROcede's installed in customer cars (v1.2). And it was at Famoso which is not a great track, with a DA of around 2500 feet with temps in the low to mid 70's
That translates to a 12.9 @ 108.5 mph time at sea level.
And probably high 12.8's @ 109 if it was 20-25 degrees cooler.
To this day, I think that was the best time on PROcede v1.2 and as good or better than most with v1.4x or JB2's (which had more power than v1.2 PROcede) got even with 93 Octane and I was on 91 Octane.

There is no way WITHOUT the v1.2 PROcede (that produced only 312 rwhp then) could I have gotten anywhere close to the 12's
Maybe 13.3 if I was on a better track at sea level on a cooler day.
But there is no doubt even the weaker v1.2 PROcede was worth .4-.5 seconds on the ET's

I agree with you that there is drivetrain loss and from 40mph to 100mph the "i" would be faster in a straight line. However, I am saying that xi has the "capability" for a faster 1/4 mile because of it's traction. Yes, xi traction is advantage is probably in the 1st 1/8 mile and this advantage is enough to be faster. BMW's awd is unique with a 60/40 split and transition into RWD at 100mph to reduce the drivetrain loss. This may be enough to have the advantage in the 1/4 mile??? Won't know until more testing is done. I really don't think there is much of an aerodynamic advantage in the 1/4 mile between them. That being said, I have yet to see faster trap speeds in the 1/4 from an xi (mainly tuned 335's).

Though these guys did it in the rain (which is a bit retarded), here's some runs between a 335xi and a 335i
The race from a dig, clearly the 335xi driver didn't launch it quite as hard as he could, as he could of/should of jumped 1-1.5 CL's easy in the rain.
But you can clearly see when traction is not an issue, the 335i easily pulls on the 335xi
That's the lighter weight, less drivetrain loss and better aerodynamics at work.

Nice race between the 3 cars. Really stupid to do it in the rain in a public road. . I see the "i" definitely pulling on the xi but it looks like from a roll and not from a stand still. Plus, I don't know the mods on each car and skill level of the xi driver WEAK!? . Enjoyed the video.

The car with the 13.25 doesn't have stock wheels/tires. It had M6 replicas I believe.

The car is definitely capable of a 13.2 stock. I would venture to say if the weather was cold and dry, it could do a 13.1 but I don't think any better than that.

Lol- I'm not so sure about the whole aerodynamic drag thing. The Cd only changes from .30 to .31 from the not-so-huge .8" difference in ride height so I doubt you'd notice anything on the 1/4mi. In fact there are some nice free calculators http://www.gtechprosupport.com/support/AeroDragCalc.htmthat show it's a whopping 1.5HP difference in aero drag losses at 100mph.

I've no evidence to back it up but I think the drivetrain loss from Xdrive is also pretty exaggerated in people's minds. You'd probably see similar or greater losses at speed if your tire pressure was off a bit.

I can't argue with the 220lbs of extra steel vs the 335i that the 335xi totes around though; that's about 19 more flywheel HP you'd need to have to run similar to a 335i in the 1/4mi.

Now, back on topic: anyone have some good numbers we can put together in one place as a sticky for those wanting to know?

So far we have the fastest 6MTs at 13.31 for both the 335xi and 335i (good work both of you BTW!). What about you 6AT guys out there? Can you top a 13.31?

if we get enough times this would make a great sticky.
