N55 Newb: what do Perfromance Powerkit cars put down on a dyno?

Anyone done it yet? Searched this forum and googled endlessly with no concrete result. The factory 300hp rating is bullshit so I was wondering if maybe the numbers on the factory approved "tunes" was a bit conservative as well. Enjoying the N55 so far but know that I will be bored soon. Keeping full warranty cover is important so an aftermarket tune is not real desirable.

Assuming that dyno was even just quasi-accurate puts your car around 350 crank then. Are the Performance Edition cars simply M Sport pack plus the PPK essentially?

Further, do you know if your Performance Edition has the upgraded hardware (aux water cooler and more powerful rad fan) as available in PPK stage 2?

Digging around the interweb, I learned that the Performance Edition was a $550 upgrade pack that included black kidney grilles, PPK software and a cheesy badge. "i" models needed to have sport/M sport pack and "xi" models needed M sport. It was available as factory order or port installed. I guess it represented good value for money considering the number of owners plunking down $800+ for the PPK installed at their dealer. None of my research indicates that these cars received the PPK 2 hardware upgrades and being priced so low, I'm sure they don't have the upgraded cooling capacity.

Anyway, I am about 99% certain that I will fit this kit soon. I realize that it leaves a lot on the table but factory-backed reliability and perfect drivability are important to me. I don't feel the need to chase every last ounce of power anymore.

Not sure about the fan, but I do have the factory oil cooler.

I guess the Sport Pack/M Sport Pack requirements for the Perf Ed. probably center around that oil cooler.

From everything I am seeing stock cars are showing around 270-275 and PPK cars around 295-300 on Mustang dynos. 20bhp increase seems underrated when it looks to be at least 25 at the wheels. Thinking about building up a car with the PPK tune, catted DP, PE, meth and intercooler. I'd like to see a solid, lag-free and repeatable 315whp. Should make for a fun car that avoids any warranty issues on anything expensive. All the aftermarket stuff is pretty well isolated and likely won't affect other components. My dealer is pretty flexible anyway.

Step one is getting a baseline dyno next week. Then the PPK goes in but still debating going for the whole kit that includes upgraded cooling hardware since I live in a hot climate. Do the kits for 2011 sedan with sport pack use ducting that deletes the fog lights? I find conflicting information when I search. The BMW corporate site is vague on the issue. I really don't relish the idea of losing the foglights.

Haven't dynoed my car so I can't report on that, but I do have the PPK. I had the same concerns as you about voiding my warranty, so I got the PPK. It was a bit better than stock, but nothing to write home about. Right now I've grown so used to it and want more power, alot more. I'm presently waiting to see what Cobb eventually comes out with for the N55, vs going with a JB4, in the future.
I'd say skip the PPK and get a JB4...if you are worried about warranty, you will already be inviting dealer scrutiny if you install a DP and FMIC. Plus, the JB can be easily removed before service appts and the like.
If you decide to go the route of DP, FIMC & Meth with the PPK, I will be really interested to see how much power you pull.

A few more thoughts:

I know on the E92's, you lose the fog lights if you do the PPK kit with the cooling package...assume it would be the same with the sedan.

I'm running the stock exhaust with the golf tee modification, and I think it sounds great now. The PPK does really help with the exhaust sound by giving it a grumble when you let off on the gas. Didn't want to spend $1000+ for a PE, or other aftermarket exhaust, for such minimal gains in HP. Plus, I figure if I ever get a catless DP, the stock exhaust will be plenty loud enough.

It seems like with a PPK, PE, DP, FIMC and Meth setup you could easily be spending $4 grand plus. A JB4 plus DP would be less than half that, and probably give you more HP. You will still be inviting scrutiny with the DP & FIMC, and I don't imagine you'll be removing them before service appts Save your cash, do a JB + DP, and remove the JB before dealer visits.

Anyway, just an idea from a cheap old guy who believes in paying attention to the law of diminishing returns and trying to get the most bang for the buck. GOOD LUCK!

I'm really not worried about dealer scrutiny regarding a downpipe or FMIC. As I said, my dealer is pretty mod-friendly and none of those components are likely to fail and/or be the cause for anything else to go wrong. I mean, nobody's intercooler just breaks. What I want to avoid is that worse case scenario of engine failure or turbo failure and the dealer's computers detect a tune and the info is logged for BMWNA to see. My dealer claims that even a piggyback will store shadow codes that corporate can see if they have cause to look. Dunno if that is true or not but I don't plan on finding out.

I am primarily looking for a lag-free experience and ultimate drivability, not building a show car for making street racing videos on the intenetz.

I posted this before - but since you asked-

I have a 2011 135i with the PE and the PPK. The before is stock with PE and the after is PPK and PE. Before 270.5 hp 290 tq. After 294 hp and 336 tq

This was on a Dyno Jet

I am very pleased with the PPK and the PE. They are a great combo. The sounds fantastic and the power is a noticable improvement. However, it is an improvement and not a transformation. If you go into it with that expectation I think you will be pleased.

Why not go the Dinan route? I mean you'll lose your "CPOabilty", but Dinan matches the BMW warranty, and you'll get more power than with a PPK.
I had the PPK and I was unimpressed.
It's just a thought. I love my Dinan stage III.
The only trouble is, it isn't cheap, and for stage III you do need the upgraded oil cooler and intercooler, which can easily take you into a few thousand. You can easily do stage II without any further hardware upgrades and it will provide more torque and horsepower than a PPK.

Peak Horsepower: 355 @ 5300 RPM
Peak Torque: 401 @ 3500 RPM

Stage 3:

Peak Horsepower: 373 @ 5300 RPM
Peak Torque: 408 @ 3500 RPM

I am really unclear as to how the Dinan warranty works. I'm afraid of being caught between the dealership service dept. and the Dinan reps in the event of a serious problem. Kind of like having an aftermarket warranty.

I'm also unclear as to what Dinan's stance is on additional aftermarket equipment. For instance, say you have their tune and later install an aftermarket catless DP. In the unlikely event of turbo or engine failure, the dealer would probably pass the buck to Dinan. They would certainly start asking questions about what is or is not installed on the car. They might even ask the dealer to produce any and all stored fault codes for review. I'm thinking that they would spot the faults in a second and deny the claim. I might be wrong but I don't want to find out.

There is one simple rule:

You buy non-OEM aftermarket part, you loose warrenty on that part aswell on all parts related...

It doesn't matter if it's BMW or Dinan...

Agreed brother, but I did get warranty work done with Dinan parts on the car- an engine mount (replaced free under warranty not related).

The likelihood of something failing due to a Dinan part is relatively low- they work pretty closely with BMW in regard to how their parts are tolerated with the OEM systems.

But hey, you know they say -pay to play folks. Otherwise stay stock. That's how I see it.

All I know is I'd rather be with a failure and have a snowball's chance in hell of having it covered under some kind of warranty relating to BMW then have some piggyback and depend on some third-party vendor to clean up the mess, sifting through cryptic error codes and emails to get me back on the road.

That said, any kind of tune is pushing your car beyond the OEM limitations, and it is going to put some kind of wear and tear upon the engine and all its related parts.

There is no getting over it, or around it. There is no "safe tune" out there.

Everyone has their preference in tuning, and I can respect them all- this just happens to be the right choice for me.

The PPK is okay but it left me wanting more. I went the PPK route- and didn't even notice it really.

Good luck with whatever you decide Ninja.

There is a rather big thread with lots of review on the PPK...

I'm happy with my PPK. It makes the car as it should be from the factory! But it is def not a lot that you get more...

I do have a second reason why i'm happy having the PPK... The burble is really nice

Dark_Knight_335: We don't have Dinan here You can be sure i would have your stage 3 aswell...
