dinan stage on 2011 335 IS

I had Dinan Stage 2 Installed On My 335 IS With Eight Thousand Miles On ODO. Seem To Have Lost The Bottom End. I Have Gained Some On Top. I Cant Tell How Much Because I Dont Want TO Get A Speeding Speeding Ticket. Strangely The Gas Mileage Around Town Has Gone Up By 2 OR 3 mpg. I Am Thinking Of Adding The Dinan Intercooler @ Oil Cooler At Some Later Date. LOUIE MENDICHI aka RED LUIGI

Exclusive of the warranty issues you really need to go with COBB or BMS for a 335is tune. A stage 3 Dinan will produce 378 horsepower at the crank & a stock 335is 368 horsepower at the crank. Its not surprising you do not feel a big improvement across the board. On a stock 335i which produces about 300 crank horsepower you will feel a surge from the Dinan.

A tune only BMS will generate at least 419 horsepower at the crank. COBB will perform is a similar manner to BMS.

This has been beaten to death on the forum & a search on DINAN should give you the whole scoop.

Bmws site says 320/332 crank for 335is... I really missed the ball if the ISes were shipping with 360+ stock!

So RWHP should be like 260-280 and like 270-290T

On a dyno with 93 octane fuel I got 319 WHP. Two others in my test group in different parts of the country got 317 & 322whp. 322whp X the 15% whp to chp loss factor is 370 horsepower at the crank.

WHP for stock 335's is generally in the 270 range

The IS, 1M Z4IS are underrated. The stock 335 is just about 100% accurate overall. That being said the older N54's are more powerful than the later versions. Both versions of the N54 are more powerful than the N55 despite the fact they all are rated at 300 crank horsepower by BMW specs. BMW has been fudging ratings for a long time. The IS 1M Z4IS are underrated for marketing reasons to keep a solid spread between them & the M3.

Assuming the rated crank number is good you would expect a M3 to put down 351whpon a chassis dyno. Since a 335 with a tune is quicker than a pure stock M3 all the numbers from the Dynos are in overall proportion to each other. Maybe that's why BMW is going turbo I6 for the new M4.

EDIT the dyno is an M3 stock & with some mods. The stock number can be increased by about 10whp to make it comparable to other dyno tests. The dyno is done on a SAE spec most posted dynos are done with a STD spec. The difference in specs will add about 10WHP

My 2012 335is became much punchier as the miles increased. At the first 15k service it felt like they updated the software as the car felt even stronger. Now at 21k its even faster yet. You may want to give the motor time to break in more before doing anything else. It may get you where you want to go as is. I was reading the Dinan tune has been problematic in some of the n54s. BurQ may chime in on that.

OP,

S3 flash is where it's at, and for only a few $ more btw...if you're already planning on going w/ the IC & OC.

But you already knew that, didn't you!



As a side note; stay away from the CAI, it will delete one of your aux fan coolers. The stock air box is fine as is, in this case.

^From a stock 335is?? Or....is this with an upgrade? I know this is slightly off topic....but I have a new f30 N55 on order (waiting to be shipped from Germany) and I've been tossing around the M Performance Package vs the Dinan stage 2 when it arrives for the f30. If those 335is #s above are legitimate, maybe the PPK would put me close to that and that's all I'd need? Originally I was leaning toward the Dinan Stage 2 (when it's released)...but I certainly don't want to take away from my low end torque. Thoughts?

Not trying to start an N54 vs N55 debate....but it seems the PPK on the N55 puts out the exact same "claimed" numbers as the 335is....no?

Add the Dinan FMIC, Dinan Oil Cooler, aFe Stage 2 Elite intake, downpipes, and change the tuning to someone else like Cobb . Even after doing this you will still have power left on the table to go through

Edit: "aFe Stage 2", there is no aFe Stage 3 yet or ever will be.

Yes but no. Claim is the same but the real numbers are not. N55 PPK maxes out at 1-1.5PSI over the N55 base max of 10psi. The IS N54 maxes at 14.5PSI.

No ax to grind on my part have both an N54IS & an N55IS-PPK. The N54IS is just grossly under rated by BMW.

EDIT: Added this Dyno graph of 3 consecutive pulls on mine when the car had about 1800 miles on it just before adding the JB4. Car is pure stock running 93 octane fuel. Ran the test myself so I am confident of the results. 319WHP + 15% for BHP = 367BHP

The other IS cars I am testing some JB4 software with are all in the same range on the same type make of dyno. There are always differences from machine to machine & even the same machine on different days.

That being said all our baseline runs are close enough for government work. One car is new. Picking the 135IS up on Thursday & will get a baseline when its past break-in. I expect it to fall in the 295WHP range or 340BHP

Though minute, you mentioned the N55 maxes out 1-1.5 psi higher (with the PPK) than a stock N55. I was under the impression that the PPK didn't change boost at all, and instead messed with the intake and other minor mappings. Are you saying the PPK DOES affect boost (even if very minor) on the N55?

I don't think there is a stage 3 intake yet, just stage 2. Is it worth the oil cooler? Also the stage 2 without the elite outputs the same power and its cheaper. I thought the is cools the oil enough with its stock setup. Good info here

Yes the boost is limit is increased on the M55 by + 1.0 to 1.5PSI with the PPK. This was confirmed to me yesterday by Terry Burger the developer of the JB4 & owner of BMS who has created a JB4 for the M55 engine. The N55 JB4 version increases this to about +5PSI over base.

Have not has a chance to play with or log a M55 but would expect all the horsepower increase to be boost & ignition timing related. Doubt the intake is tweaked because intakes don't really do anything for performance under 390-400WHP

If he already has a Dinan S2 flash, the cost to go to S3 is minimal and probably a good idea while under warranty given he's already made the commitment. Then after the 4/50 go to a Cobb flash for more fun.

Correction, that's 398 hp & 429 tq on a Dinan stage 3. At 30hp over an 'IS its no contest. And I believe, correct me if I'm wrong the 368 number is a short term over boost, for like 7 or 10 seconds, no?

You are correct "that's 398CHP & 429WTQ" at the crank for the 2007 to 2010 N54 & the all 335IS N54 Stage 3. My bad, was looking at the Stage 3 tune for the 2011 & on N55 by mistake which is 373CHP according to Dinan.

Stage 3 N54 is 398WHP & 429WTQ 15% = 338WHP X 364WTQ for stage 3. A base 335IS is 320WHP & 365WTQ. The Stage 3 N54 advantage is 18WHP over a stock 335is & torque is a draw for 7 or so seconds to the point WHP takes over.

The OP was talking about a N54 Stage 2 advertised at 378CHP by Dinan. 378CHP 15% = 321WHP 1whp more than I dynoed & 4whp less then my test partner got. This is why he is looking for more seat of the pants acceleration than he got after the Dinan Tune.

Apples to oranges Dinan's Top Stage 3 vs. base JB4 in the 335is changes the metric quite a bit. The base $505 JB4 tune brings the 335IS up to 375WHP & 414WTQ on 93 octane gas + 37whp over the Dinan. On 40% E85 into 93 octane it moves up to 395WHP & 417WTQ +57WHP over the Dinan. This is my current street mix. If you want to spend Dinan Stage 3 level money on a tune the JB4 & supporting mods should be in the 450-500WHP range.

I agree with bear, dinan is not worth it for the price/power it delivers. Jb4 or cobb aggressive maps will put you over 400whp and are easy to remove for warranty work. I saw some saying they purchased dinan only for warranty reason...but now is it worth to spend that much money, wait 4 years and then purchase cobb or jb4? By then you will want the new M3 just saying...

The OP was talking about a N54 Stage 2 advertised at 378CHP by Dinan. 378CHP 15% = 321WHP 1whp more than I dynoed & 4whp less then my test partner got. This is why he is looking for more seat of the pants acceleration than he got after the Dinan Tune.

Apples to oranges Dinan's Top Stage 3 vs. base JB4 in the 335is changes the metric quite a bit. The base $505 JB4 tune brings the 335IS up to 375WHP & 414WTQ on 93 octane gas + 37whp over the Dinan. On 40% E85 into 93 octane it moves up to 395WHP & 417WTQ +57WHP over the Dinan. This is my current street mix. If you want to spend Dinan Stage 3 level money on a tune the JB4 & supporting mods should be in the 450-500WHP range.
Referring to your 1st post; I figured you meant stage 2 but you mistakenly wrote stage 3, so I wanted the OP and others not aware of the dif between S2 and S3 not to be mislead.

No doubt, at $500 a JB4 is the cheapest way to add performance to any BMW, no argument there.

By then you will want the new M3 just saying...
Agreed, the new M4 might be a game changer with its new tri turbo motor. Might even come perfect right from the factory!

According to Car & Driver; 2011 BMW 335is
Power: 320 bhp @ 5900 rpm
Torque: 370 lb-ft @ 1500 rpm (est)

Break(b) is the same as crank.

Since math is your example:
320bhp -15% = 272whp(335is)
398bhp -15% = 338whp(Dinan S3)

The net is 66whp more with a Dinan S3, wheel to wheel. 18WHP difference is incorrect.

You seem to make a lot of mistakes when Dinan is in the subject matter. What gives?

FWIW I decided to dig up an old dyno of the Dinan Stage 3 for the 335is in which my car was the very first 335is to get the Dinan Stage 3



339 whp and 380 wtq which was done on a mustang dyno averaging about 40-50 whp more over stock. My base line was 303 whp and 333 wtq

Best track time for Dinan Stage on the N54 was 12.5 ET @ 108 Mph , best speed trap was 111 Mph in the 1/4 mile

From since then I have moved on of course with another that takes full advantage of the Dinan mods

Edit: This was done on a mustang dyno, a dynojet in general renders over inflated numbers. So on a mustang the number are more closer to being realistic
