Dyno BMW: 2008 BMW 135i @ the Dyno

[Mrguill]

What tune did they use?

[boostedscooby2006]

thats a 15hp lose at the wheel ..... good grief that amazing compared to other 30,000 dollars car( evolution and sti) and 55hp with a reflash .....

[33486sac]

@boostedscooby2006 This is actually a 40k car. I just bought one loaded for 47k.

[hugokupas]

and the old mstang gt500 with just about 447 hp ? :)))

[toyotas2006]

The stock 135 makes more than 300HP at the crank

Easily 320-330

DrFill

[EVILWS666]

The results they showed on the video were probably RWHP, not crank HP as they listed.

[4MATICbenz]

285 out of 300hp is making it to the wheels.

That's only about 5% of power getting lost in the drivetrain. VERY impressive.

[forry90]

actually that means that the hp from factory was underrated.

[euro944t]

BEWARE , 135i is dodgy @100mph. I can let go of 928GTS or 944T or M3 wheel and it drives itself. 135 has little downforce, sits high on 18", steering is loose goose compare to M3, 911, 944, 928, M Z4, B7, 550i. 335i are less loose than 1.

19" M6 replicas would help cure both 1 & 3 with ground control Adj springs.

The 135i comes only with a sportier M suspension setup thats lowered by 0.6 inch compared with the 128is.

New BMW 3 & 5 don't feel solid anymore, like Nissan, Acura, etc

[euro944t]

2008 550i with M5 body & 19" is the best midsize sedan around. Never driven the XFR Jag, CTS-V, or AMG MB but read that Jag is gizmo failure prone & Benz is not as linear shift as 5 & 7.

[NIGHTMAREuki]

@euro944t nissan is not solid at speed?

i've driven my 03 maxima @ 115mph(107 mph based on navigation) and people in the back didnt even notice it and car was 100% stock, no fuss no muss, no shakes no drifting to the side.

that was on the way back from Niagara Falls in Michigan

[euro944t]

@NIGHTMAREuki

We hit 170mph traveling to Indy 300 in Kansas in SMG conv M3. The side mirrors and wiper blades did not budge, the wind was quite with top up of course. My 944T does that 110mph in 3rd gear. I like Maxima, but not top end, let me out please

[NIGHTMAREuki]

@euro944t yeah, but you're comparing a grossery getter to a sports coupe.

now i have 03 manual max after a school buss hit me head on this past December, i dont remember what my 3rd gear tops out at, but my first is 40mph, and 2nd is ~65, i suspect 3rd would be ~90 or so.

[euro944t]

At 171.7 inches long, the 135i is 8.9 inches shorter than the 335i coupe and 1.4 inches narrower at 68.8 inches, and it rides on a wheelbase that is four inches shorter (104.7 inches). Despite the smaller footprint, however, its only about 200 pounds lighter than the 335i, according to BMWs figures. Thats because much of the architecture is carried over, including the multilink-rear suspension and strut-front arrangement.

[lowfiwhiteguy]

I'm a newb to tuning. What did they do to drive it up from 280hp or so to over 340hp?

[lmrcobalt]

DEM Tune flash, just increased the boost.

[euro944t]

$500 software make 70ft lb torque @360 to the wheels

Boost and timing retard and unlimited gov and unlimited rpm

101oct petrol, Headers, pipes, intake would be worth it on a twin turbo. Intercooler sprayer wakes up my turbo 944 another 15-20hp

[0l0Dom0l0]

its more than likely this is stock. they produce well over 300hp standard, the figures from bmw are well underated!

[1973MaseratiBora]

I love conservative power claims.

There's nothing better than buying a car only to find out it has wayyy more power than you bargained for.

[miglior57]

what is a DME tune reflash?

[euro944t]

$400 software only.

With CAI cone and pipes and headers it will make another 15-20 lb ft

[starbury210]

340whp?? really?

[BrookeMuslim1]

its called more boost! somthing the gtr and gt2 owners all do and not admit it!

[BrookeMuslim1]

it also effects the longivity of the motor and turbos but they all trade them before too many miles and let the next poor sucker find out!

[euro944t]

After market turbos will be sweet when avail.

[goma3]

There have been numerous dynos of the 135i running default boost and getting 310-320hp. BMW was conservative in the number and this has been confirmed by car reviewers. 315hp is a more accurate value for default boost.

[damwhodat3]

310-320hp @ the wheels??? Are there any videos of this?? Wheres the proof?? I hope my 135i dynos over 300 when I dyno it in december!!!

[kinnokaizoku]

Yeah ... increasing the boost ...

It's really not a good idea if you want the engine to last more than a few years without some really expensive rebuilds.

[euro944t]

Just a head gasket.

Spike the tank with race fuel.

[TehSmartNewb]

wow!!

[Sandr0G]

Cool cAR!

[jbh1126]

that is a fantastic amount of horsepower for a stock car that slaims to have only 300 hp. i love bmw.

[redstormer75]

love the wheel effect

[abeismain]

How do i 'Dyno' my car?

[nfusco618]

Find a performance shop that has one.

[Bestever4everSince]

dynoing wont make it faster..tuning the computer will..

[ferrarimk13]

put it on a dyno. All it does is measure the actual hp and torque numbers at the wheels. Doesnt increase power. like BestEver said, its tuning the computer that increases power.

[koukicrisp]

Damn so it actually makes figures much closer 330hp and 340ft lbs. then. I knew they had to be lying because all of these other 300hp cars were getting smoked by it.

[dickcheese663]

WOW dude, very good numbers, for about another $5-600 you can get a sweet power programer that would bump that up 40hp, a bit of money but if you can afford a 135i, whats another $5-600, i would do it, bit my e28 ///M5 would get mad

[AdamsJoshua85]

Darn good numbers, considering it's posted ratings of 300hwp 300fpt

[InsideLineVideo]

Great comments. Thanks, everybody. Also, check out the track video in the Video Responses.

[BeaNz335i]

You guys run any tests after the tune?

[hanscholo]

Does this model have an optional XDrive Cuz that'd be the cherry on top.

[nonagon1]

Nope, XDrive isn't available on the 1 coupe. However I heard there will be an X1 coming next year.

[COSWORTHSVTF]

who did the tuning?

[e10rice]

wow thats a massive increase for a cheap price.

[larryshere]

oh right thank you!

[larryshere]

one question why dont you start in 1st gear why do u start in 3rd gear?

please reply

thank-you

[coboisarapatanas]

they whant to see the power at the weels so they must use the gear that has a gear ratio closest to the rotation of the engine. 4th gear in any car, has a gear ratio of almost 1, this means that the weels spin at almost the same speed of the engine and the power at the weels is almost the same of the engine(with ~10% losses ate the weels because of the transmission and dif).

[BeaNz335i]

these cars (135i and 335i) got the potential to be the next supras

[sspope]

except they can handle and supras can't.

[Mrgnoyeneg]

not sure if internals or the transmission can handle 800whp like a supra...but the twin turbo engines made by BMW are my favorite..dare I say..even more than the m3

[coolerdude44]

i'm with you there, i think i'd buy the 335i over the m3 because you look like such an asshole driving the m3.

[biglandfarm]

agreed

[87toyotacorolla]

ya boi ya clown

[BeaNz335i]

supras cant do 800whp on stock internals but they can run around 17 psi stock which is a lot but not 800 hp

[koukicrisp]

Where are you8 getting the figure 17PSI from. I have PERSONALLY seen thm run over 24psi STOCK. PSI is not what limits your engine.

[BeaNz335i]

okay the motor may be able to take 24 psi stock but if you want your engine to last for a while i wouldnt run that high of boost on stock internals

[koukicrisp]

Yeah you're right about that. But there's way too many factors to say 17psi like that. It depends on TUNE, the CFT the turbos puts out, and the fuel taht you are using. If its a car taht runs methanol like my boys it can run that on a pretty regular basis or a car that runs on 106 octane fuel. It's more HP that kills an engine because if its running 24psi on some small T25 turbos making barely more than stock HP it can run that all day long.

[112namrepus]

WOW that must be an M3 KILLER after that flash!

[DemonOfRazgriz89]

285hp stock is pretty disappointing from a twin-turbo 3.0L I6...

[112namrepus]

300hp at the crank so not that much lost. Still pulls a 4.7 sec 0-60mph

[Atheismrulez]

It's got two very compact (possibly ceramic) turbos. I'd doubt this car is putting out much boost at all. So no, it's just fine.

The GT-R is much more powerful because it's has a better-engineered engine, it has more displacement, and much bigger turbos.

[DemonOfRazgriz89]

hmm very true

[Storvick1011]

Finally someone who isnt an idiot

[sspope]

Except this engine is made for supersmooth everyday driving, not jerky power boosts. It's how it delivers the power.

Why are you comparing it to a supercar???????

[ethosflux]

True that, these are low compression turbos and I've heard honor stories from the forums already about them blowing up past 12psi. Still, it's balanced since this is a comparative large displacement motor to be turbo'ed. 3.0L plus a twin system and you get alot of instant response and power even on low 7-8psi boost. BMW motors are pretty high compression to begin with too so. I wonder what this system would look like with an upgraded single GT35R and a built forged low compression 3.0L.

[marcomariaz26]

It's only 15 down from the crank, that's amazing.

[ethosflux]

big time! Or bmw is underrating from the factory.

[hustler539]

What's a DME tune reflash?

[gunluvS14]

wow, 285 to the wheel in stock form? and 340 after reflash. very nice

[legendray2008]

Very Cool !!

[xIv3n0mIx]

Great looking car.

[konadude92]

that thing just sounds like a fan. horrible sound horible.

[justincrap]

What a machine .

BMW forever.

[SharurottoJjang]

sweet!

[turbo311]

Gotta love tuneability of factory turbos. Didn't know it's not intercooled.

[slimbothetiger]

it says 2008 on the video. but in the title it says 2009.

[asdfgoogle]

So is this the 2008 or 2009? lol. The video contradicted the title of the video.

[saloom431]

135i sucks and its not worth its price

[wildbloodydragon]

Why is that?

[sspope]

quoting Clarkson:

"The 135 coupé is the best car BMW makes."

[saloom431]

135i for people who wanna show themselves cool u no

[sspope]

135i is for people who want a car that offers both comfort and sportiness. There's no other car in its price range that can do it better. THE END.

[gephross100]

sc400 :x

[sspope]

Bad car with a rough ride. Clarkson voted for it as the worst car of a year.

[gephross100]

that was the sc430 not the sc400.. two diff cars. 1uzfe vs 3uzfe and the sc430 looks like trash.. car lost all of its muscle when they let euro fags design the car instead of in the states where the sc was originally designed

[sspope]

so wut?

[euro944t]

1 Feels like a short & light 335 to me. Great car for city. The 335 has the longer legs wheelbase & weight for the highway.

If you love the 335 you will like the 135i, unless you are tall or fat, or haul rear occupants.

[sspope]

it's a softie.

[euro944t]

Rumor of M1 coming soon.

[flatoutfullspeed]

it is a m package for the bmw 135i

[GangstaDogg21]

@euro944t that's gonna be called 1 Series M coupe.

[brn2xlr8]

Have you driven one? Clarkson also tore up the C6 Vette for being a harsh ride and that's one of the most "day-to-day" drivable sports cars I've ever driven. Besides, quite a few real automotive journalists thought it was a great car. I'd say make your decision after you've driven it.

[sspope]

C6-leaf springs and "one of the most "day-to-day" drivable sports cars" ??????

Go tell that to your mother!

[edersiomoran]

for a car ranging from 30 to 50 grand. There are plenty. Shop around.

[koukicrisp]

ehhh, that's still a weird statment because it has no direct competitor at all. It's easy to be the best in it's class when it's the ONLY one in it's class. It's closest competitor is a 370Z which was NEVER made to be a luxury car at all, but does outperform it. So I feel like that statement hold no water based on the fact taht there are no other competitors. Except for maybe an A3 3.2 Quattro which costs 10G's less.

[Mrgnoyeneg]

I have a G37 right now..which competes with the 335i..i guess performance wise the 370z competes with the 135i..there is also the sti and evo..2010 versions are coming out soon since the evo skipped 2009...are there any other cars im missing..cuz the top two cars I want to get as a next car are the 370z and 135i

[koukicrisp]

Yeah it has performance competitors but no actual class competitors as in Entry-Luxury Sport Coupes. All of those other cars are just plain old raw sports cars not luxury sport coupes.

[sspope]

Oh, you again? I actually don't like the 135i that much, but I hate when people are comparing it to hard-core sports cars.

[koukicrisp]

Hm, I would love to see where I compared it to a hardcore sports car. I could have sworn I said that it had not competitors because it wasn't a hardcore sports car. Reading is fundamental.

[sspope]

My point is that you just can't compare this quick-everyday 2 door family mover to grippy 370z, you just can't.

[MDKlavir]

is edmunds payed off by bmw because there always saying there better than everybody and i know audi's are better than bmw's

[350Zed]

Audi's are for people that want to look like they drive fast, but qho really don't want to drive fast.

[ethosflux]

Afraid I have to agree most of the time. the r8 is lovely, but the rest of their product line is all about fancy and pretty interiors without alot of grunt to back it up. BMW has always been about function over form, while Audi has been the opposite. Even the TT and S4's aren't impressive even when compared to a mildly modified WRX STI.

[DoggyDaTroof]

they had the Merc win over the BMW

[DoggyDaTroof]

and the 370 over the 135 and the ... you get the point.

[GTRnev8820]

wow thats some power for 3L turbo

power up

[loneshark2000]

wow !!!! at the wheels !!! so add 15-20 % and you got 391-408 at the crank !

[ethosflux]

Probably more like 370hp, but still hella impressive for a reflash alone. An aftermarket downpipe on this motor alone adds like 30horsepower, with coldairs adding 15. So yeah, there's ALOT of potential out of this motor even on the stock turbos.

[quuaa1]

Yeah, but then you'd have turbo lag. BMW went with two small turbos non intercooled for that reason.

[DONNYBOYY28]

your wrong the car has a single intercooler!

[ethosflux]

but what? Your completely wrong. Adding a downpipe and a cold air will reduce not increase turbo lag as the system can breath and spool better. You'd only get additional lag from upgrading the turbos to ones with larger compressor wheels. I even wrote "even on the stock turbos", which seem to have alot of potential with only the supporting mods done. I think 450 crank is reasonably possible without touching internals or the turbo system.

[stevewesthead]

such a tight car

[keviiinn]

wow that's very minor driveline losses then. nice

[ethosflux]

Or alternative, bmw is underrating the factory crank HP. It is an open diff rear wheel drive, so it's does have the least amount of possible driveline loss though.

[keviiinn]

this is at the wheels?

[stevz0r]

first figures were

[Yoda8232]

Probably because it's rated by BMW at 300HP and 300 ft-lb torque for regular.
