hellow

i want to get 500+ whp from my car
its bone stock at the moment
i have injen cai , turbo smart diverters and cobb but it not installed at the moment

how can i get 500+ whp without meth ?
any turbo kit out there other that RB's ?

my gear is DCT-7 , can it handle the power ?
its fine with me if i will not use my current mods

[ihc95]

Vargas Stage 3 or Single Turbo will get you 500+whp. Doubt the DCT can handle it though.

Wrong tranny for the power goal.

problem with the tranny is the TQ capacity

[a7med606]

there is no clutch upgrade ?

[a7med606]

who can offer me a turbo kit ???
i want a ready and tested one

I think you might have an N55, not an N54. The only N54's that came with DCTs were the 335is, I believe. If you do have a DCT-7, and an N54, then you can get to that power level without meth. As for the transmission, it should be able to handle the power for quite a while, depending on how much abuse you give it, given the increased power levels. The DCT is the same one that's in the E90 M3. There are guys pushing 680whp, with supercharger kits. The main difference between the 335is DCT, and theirs is that they have a transmission oil cooler, which sits in the front hand side. Its the same type as the oem 335I oil cooler, and is made by the same company. You will need to retrofit this trans cooler, or your transmission will go into limp mode fairly quickly, and often.

While a supercharged M3 is putting out close to 680whp, its no where near close to putting down over 500wtq like the upgraded twins on the N54 which is what kills transmissions especially at low rpms. As it was said earlier in the thread, the DCT will simply die an early death if you decide to go this route.

Once you modify oem equipment, all bets are off. However, even with high power levels, it would seriously depend on how the car is driven. If you are the everyday WOT type, you will shorten the life of a DCT with bone stock power levels.

Non US 335i's have a 7DCT option available to them. Its unknown if the DCT can handle 500+ but it is outside of the units factory specs.

[135Pats]

I strongly doubt DCT would handle the torque that would accompany 500whp on these motors. Right now the FFTEC single is probably your best bet.

no brother its not a 335is its 335i 2010 model
but gulf specs
we have an n54 with DCT 7 strats from 2009 2010
and 2011 we have the n55 DCT 7 too

know am looking for the power with turbo kit

[Jeff@TopGearSolutions]

Turbo Kit is not hard to find if you have an N54. There are plenty available.

That transmission can't hold the power, if it does it won't last very long.

I would put your energy towards a DCT trans upgrade (if even possible), I have no idea. Would likely require internal rebuilds as well as software changes to increase it's clamping force.

RB, Vargas, Vishnu seem to be the most popular turbo upgrades.

[Killerfish2012]

Yes, you might have to settle for less horsepower, but the car will still be hella fun to drive.

What's the max the stock tranny can handle do you know? Will his power goal of 500hp affect only DCT cars or how about the manual 6-speed cars? So with all these bolt on upgrade that I am seeing with some people pushing somewhere around +400rhp/awhp, that's pretty bad for the tranny hun?

[BQTuning]

The information posted on saying that DCT found on the 335is, M3, Z435is will not handle 500 wtq is pure speculation based off of the history on a known DCT M3.

No one is absolutely sure as the DCT programing on the M3 and the DCT N54 are different to with stand different amount power per stock specs

even so, if you were able to achieve a power level with at least 500 wtq you will have to train the DCT for it to adapt.

what I have found is some people get all this power then just decide to go out and do a dyno or WOT treating the DCT like if it was a MT or AT then start crying about slippage.

Currently the only DCT N54 that is at about 480 wtq that is Cobb ProTune by Jake@PTF is not experiencing NO SLIPPAGE.

[jippii ensio]

Yes, 500+ WHP is no problem at all.
However, be careful to tune the torque down a bit if needed. I guess DCT can take 600whp easily in the upper rev range where the torque is not too high. Luckily, this is similar to the Vishnu single turbo's power delivery.

I have 335i with 7 speed DCT EU version an also with Bmw performance kit with additional oil cooler. With my FBO JB4 G5 BMS flash running 437HP 574Nm, it is not RWP. Have Quaife and now waiting for turbos upgrade. Will see where I will get. I am also worried about transmission. Asked G power but as long as it is not build by them, they will not help me and they do at least software changes on the same transmissions.
You guys saying that additional transmission cooler would help? Any idea what part nr. It is?
Thank you

Get a bigger oil cooler. Its not nessesarily to get an additional oil cooler. The DCT oil thermal exchange is cooled by the Oil Cooler already on our turbo charged cars.

The reason why the M3 DCT cars have a dedicated trasnmission oil cooler is because they are not turbo charged in order for the transmission to share a common oil cooler like on the regular turbo charged cars.

My correction he is at 460 wtq, could of sword I seen a latest post by him nearing 480 wtq.
