If a car is misfiring stock they need to look at the above mentioned. If they still can't figure it out, let them go to the dealer.

Shiv, I have to say it seems pretty reasonable the the Dual mass fly wheel may cause some imbalance, especially with abuse. Based on your current data that you've given it seems like you might be on to something.


To others hating constantly in every thread:

I've tried speaking over with a few people about a turbo kit's performance in relation to 1/4 miles, it seems it's a subject for those with true hands on experience only. Jumping into a 600WHP vehicle not set up for drag will not show stellar results. Driver, vehicle preperation, track preperation, exterior conditions like ambient temps, DA, humidity, ETC all factor into good ET's. If you have one of those conditions not going in your favor the results may be poor. That is why a good test of a any power adder is simply a dyno. A dyno shows how the vehicle can perform in a controlled environment. Of course a dyno isn't everything, drivability is an important aspect, and that comes from the tune and turbo selection as well as other small factors in components. At the end of the day, all the people begging for results results results, need to get your own hands dirty. If your not sold on the power and kit alone, then I'm sorry but there really is not much more to offer.

Look at all the other platforms out their today and the manufacturers selling turbo kits, I can name a handful easily.... They have a few pictures, and dynos. Some of them have some drag strip time, and each time they go out the times get better and better. For people that don't have the kit that is the only results most people would need.

The subaru brz is a new platform, there is already a few turbo kits out, there are already some dyno, and there are already turbo kits selling off the shelfs. It's more then enough for everyone else, so why does this community fight it so much.

You say there are no results, but there are actually quite a lot. A lot more then other platforms would for a similar turbo kit actually.

For some reason people here are in essence asking to borrow the car for 6 months so the turbo kit can "prove itself", or they want everyone that has the kit to show them the 10's slip, with videos, dynos, logging, and real world driving on a road course. I'm sorry but that is just not how the cookie crumbles in this business or in the enthusiast market.

You bought a 335i more then likely? How long did you test drive it before you were sold? Did you ask the manufacturer for logging of the vehicle? Dynos from its brochure? It was a 40K+ car wasn't it?

My test drive was 10 minutes. The brochure told me it was 300 HP. I assumed it had it. I signed the papers and the car was mine.

A little bit of ambition, and getting your hands dirty will go a lot further. If the cost is too much to stomach then perhaps it's not for you.

There will be many risks involved in any power adder, it's an investment that won't pay you back unless your in the drivers seat yourself. Living vicariously through others over the internet... well, I'm sorry to say is a bit over-rated.

If you are seeking the power now, you know what to do. The options are out there. Pick 1 & enjoy yourself, and remember we are all on the same team here. Instead of bashing every Vishnu thread that is here day in and day out pushing the platform since its inception, you should be looking to help.

/rant Excuse my typos I dont feel like fixing all of them LOL

I Googled 135i chip and I bought my car the next day. No test drive needed! Wish I bought the 6AT to begin with though.

I'll be sharing my venture openly on both forums as updates come about. as of now it's a T4 6466 single project. the turbo is on the way and the car will be going in for a custom manifold soon.

That's an excellent turbo. I have one on my Talon. Looking forward to seeing results.

Over in the Porsche world they went through issues with their dual mass flywheels many years ago. Some of the signs/symptoms they see when their DMF goes bad is throwing misfire codes, actual misfires, and a brief heavy clunk sound at startup or just before the engine stops rotating when it's shut down. Since this is a new development in the BMW 335 arena I'm looking forward to hearing about other peoples experience and observations. Maybe if we share enough info we can get to the point of diagnosing a bad DMF more easily.

Did any of these single turbos with DMFW replace their flywheels when they upgraded their clutch? Or just resurfaced?

Same here! Then I couldn't wait and I put my jb3 in with 800 miles on the clock

[cn555ic]

I didn't even test drive my car when I bought it. As soon As I heard turbo charged I went and ordered the convertible! Lol. Didn't even drive it at All but read up on it. Pretty Much knew turbo charged cars were very tunable

I only have ~20k miles on my car and I wanted to avoid chattering and any other weird noises with the Lightened SMFW but now its obviously coming around and biting me in the rear end... :-/

Hey guys,

for anyone that is in need of a single mass chromoly steel flywheel, we can supply a 10 kg (22 lb) unit for either "8 bolt" or "6 bolt" applications.

However I can personally attest to the fact, that even a 22 lb flywheel will induce audible driveline chatter and gear rattle at idle, in particular when the air conditioning is cranked.

Swapping out your factory fill transmission fluid for Motul Gear 300 (75W90) does help the cause quite a bit, but when the AC is running at idle and the clutch is not depressed, it will still sound like you have a bucket of bolts rattling around in your expensive ZF gearbox, lol.

Cheers,

Justin.

P.S. just a "few" shameless pics.

If I manage to sell one of our flywheels, Peter the owner of Advan will be shocked!

Whilst we manufactured this particular flywheel over a year ago, to date we have sold zero. Obviously it's tough to market an upgrade, that makes your BMW sound like it is well and truly broken, haha.

[trbolexis]

Pricing? Dos it work with stock PP and Friction disc?

Product looks good!

LOL, at least you guys are honest! And FWIW, I think the stuff you guys manufacture is extremely pretty and well made, and the prices on some of the things you make are reasonable...it's the shipping that hurts. Before the SPEC steel FW came out, I was seriously contemplating sucking it up and getting one of your FWs at some obscene shipping cost...perhaps establish an American distributor who can stock items?

+1, but i still got their meth tank anyways

Two quick questions on the problem being solved.

1. Didn't Carl Morris originally post the flywheel theory on the N54 platform?

2. Has the issue been proven solved by an actual installation & on street/track runs?

Really ... :/ ... here we go again.

1. tmo335tt actually had an expensive o-scope, hooked it up to his car, and verified that odd waveforms were actually being produced. then did research, a lot, and for documents.and essays supporting his findings.

2. every car that has a SMFW making these power levels does not have the misfire.

Off topic, but what kind of scope did he use? Any screen shots? Scopes are one of the most powerful tools around - I always love to see how they are used!

1. Did you come up with that question or did you get it from someone else?

2. Not yet. Hopefully next week.

Have you read the threads? The first question doesn't seem very helpful in any sense. The 2nd has been answered multiple times. Do you have any relevant and helpful information to contribute?

Why don't you ask Carl what kind of hands on research he performed. You already know what I did.

He was one of the first to catch on to what I had found to be the problem while everyone was guessing and complaining that I hadn't told them yet, if that is what you are wondering about. It doesn't even matter, give Carl the credit or yourself. I stated a long time ago that I wasn't looking for anything in return for all of my hard work. My problem is solved, I'm happy and my car is fast as hell because of it.

If you still have doubts and believe otherwise then why don't you do something to make your car fast for one and then prove to the rest of us that you can do it with the stock dual mass flywheel. Do it...I dare you.

[BEAR-AvHistory]

I have no interest in making my car faster so its just interesting info to me to see how the problem is solved. To me street strip cars are a waste of time, If I am racing its in a dedicated car trailered in. So I guess the bottom line, after all the outrage at the question, is you all THINK the problems is solved but no no one knows for sure on the N54 platform.

Knit Pick, its obvious the only way they will know truly for sure that the DMFW is the problem is if they take a DMFW car with misfires and replace it to a SMFW, and the misfires go away, which he is in the process of doing... Do you want information that pertains to your car or not? Everyone said it was an idea, no one said it is THE SOLUTION, just have a pretty good idea that it COULD be the solution. If you're not going to be running high hp, and don't think this will effect you, do not speak. And yes the thread title says solved, when really it is solved in theory at this point, but if you read through the thread like everyone else did, you would see it's not for sure yet.

/rant

I hope this solves those misfires!

[David1]

Shiv,

I wonder if the DM flywheel is also the source of the weird vibrations that go through the car under high load, high torque situations like full throttle and 17+ psi at 2k to 3k rpms. What do you think?

Sounds good.

To be honest I did not wade through the whole thread but took the OP headline at face value, my bad. Reason I have interest is because way back when I got whacked for trolling when I said it did not make any sense what so ever that this system could be pushed through the stock drive train.

Shiv assured me I was wrong about that.

If you read the thread you'd see that we're looking for info to help push this platform forward since this issue affects all high HP 6MT cars. I know you've been around a while and probably know these cars well, if you can contribute we'll all be thankful.

At the time Shiv was giving advice based on the best info currently available. I see no wrong towards you.
