I'm trying to think of how an object that is more or less static (except for spin), has no moving parts of any kind, perform it's basic functions (absorb/ dissipate shock and vibration, heat and momentum sink, and base for the clutch) can cause much of those symptoms?ĭoes it flex? Does it have some kind of resonance? Does it vibrate? Is it loose or hitting inside the bellhousing somewhere? I'm honestly intrigued a little.maybe it has a crack? In this case it's a chunk of billet steel machined per certain specifications. And as far as other issues, consider what a flywheel is mechanically. That sound happens just due to gear meshing, and I've heard modern cars with no mods at all crank over like that. Perfect fitment.Īlso, while I don't consider myself an 'expert', I have been working on and building cars for 30+ years and I can tell you that #1 (Starter Misalignment) doesn't have anything to do with the flywheel necessarily. I used OEM 2.7 flywheel bolts on my S6 with the TTV hybrid flywheel. Hint, don't ever remove just the engine unless you're an absolute pro.I learned that the hard way. I'll keep updating this thread as I go along, plan on pulling the transmission and mating it back up with the engine tonight in order to start reinstallation of the engine/transmission assembly. I'm wondering if this could all be due to a starter misalignment or whether I've done something entirely wrong in the installation? You can see the part number stamped on the flywheel in the picture where I'm weighing the aftermarket flywheel. The more recent one that is more comprehensive of the problem: Here are my videos so you can see and hear the problems that I am having with this installation: Wrong Flywheel Received: TTV LW Steel Flywheel - Is this fitment normal?

Audizine here has the best information about the issue that I can find and will link the applicable threads here:ġ. There have been multiple issues with this flywheel setup, and I have done my searching to this point through multiple forums. When I got the clutch and flywheel installed first: TTV B5 C5 RS4 S4 Allroad 2.7t to B7 RS4 4.2L V8 Clutch Conversion 3509Ī Cautionary Tale in Starter Alignment in an Audi 2.7t Engine I have an extensive amount of pictures on my build thread that you can view and I won't link them all here, feel free to scroll through the linked thread and look at them. SRM also sells it, will link them here too. I bought the B5/C5 2.7t to B7 RS4 clutch conversion flywheel from TTV.

All that said, I have read things online that seem to say the opposite so who really knows lol I was paying him to do £5500 worth of work in my car so took his advice but sure there are many s4 owners running a single mass that will give you reasons why they are, in their opinion better.I am building an Allroad and trying to do everything at once, which is usually a mistake. I don't really drive the nuts off mine so was happy to stay stock. I took his advice when mine was done and went oem dual mass as he seemed to know his stuff and had great reviews from others. On other b6 models where you can easily add loads more hp a single mass often works well. He did say that if you plan on massively increasing power then a single mass and uprated clutch system can sometimes be the way to go, but squeezing loads more power from the s4 v8 isn't easy without substantial work at more than the cost of the average b6 s4. I can't remember his exact reasons, there were a couple, but think it was due to them struggling with the torque in low gears but this was over 2 years ago so may have my wires crossed. He had said that on the S4 he would stay with the Dual Mass as the single mass units seemed to fail prematurely.
