Take it from me, you don't want to have to do it twice (oups!). Pay careful attention to aligning the bolt hole with a different shape to the matching hole on the crank. You dip them in engine oil while bolting them in, and you torque them criss-cross. You need to getВ 9x new BMW flywheel bolts (11227520706). You can't reuse the OEM bolts are they are encased in the flywheel. It's something you do usually while you're in there with other maintenance and upgrades to the transmission, driveshaft, etc. The flywheel isn't exactly a DIY install: the exhaust, driveshaft and transmission are all coming off.

Nitriding is a heat treating process that diffuses nitrogen into the surface of a metal to create a case-hardened surface. The flywheel was later tested on supercharged S65 race cars for high temperature applications and a nitrite coating is now standard on all DCT applications. There is one known failure in the world on a DCT M3 race car. It is high speed balanced at TTV's facilities as seen on the last picture. The flywheel is milled from carbon steel and the spline is hardened over the OEM dual mass flywheel.

This remains TTV Racing's main market considering their UK manufacturing headquarters. They were then brought to market mostly to European race teams in 2012. The first units were tested on race cars at the Nurburgring for 12 months before made commercially available. The TTV Racing DCT & MT S65 lightweight flywheels were initially developed in 2011. Stay tuned as I set up another winter pre-order. ItвЂ™s definitely something that should be on any DCTвЂ™s owners list. This flywheel is a lite version for BMW E24 635CSI M30B35 with standard clutch. It changes the driving experience and gets us ever closer to challenging GT3s. Produced in the United Kingdom, TTV Racing flywheels are CNC machined and forged with Chrome Moly steels, the ring gear is part of the flywheel to improve the strength and the reliability when used in very stressful conditions. It drastically improve the DCTвЂ™s shift operations everything happens quicker now with no added jerkiness. It fixed a common complaint about the sluggish mid range of these engines. I unwillingly hit the 8,600 limiter a few times, catching another gear much faster than it used to. On my first test drives, I thought the clutches & flywheel were slipping off each as it was so much faster. The science to it is simple reduce the initial moment of inertia to improve performance.ДЄs you reduce rotation weight further out to the radius, the more drastic the effects are at low rotational crankshaft speeds. It will shave off 18 lbs off the early production DCTs. The TTV flywheel shaves about 8 lbs off the updated & lightest OEM DCT flywheel. You can make it out starting at 20sec, oil at high temp, no trickery that hides chatter. This allows is to be machined to a tighter package, further limiting rattles. ItвЂ™s higher density than aluminum, commonly used by other brands. The TTV flywheel is a single mass design milled from carbon forged steel.

One of the reasons why is the DCT has no throwout bearing, a common source of rattling even in a stock E9X M3 manual transmission. ItвЂ™s unlike any other lightweight flywheel sound IвЂ™ve heard - you really need to look for it with headphones. sooooo I want to try and utilise the OEM setup as much as possible because it looks fit for purpose in that I can utilise all OEM sensors wiring etc that I already have, its well protected and gives me plenty of room to fit my alternator, in short so long as I dont need to re-write the laws of physics I'll be running a flywheel mounted setup.A post shared by Matt can only describe it as a slow, heavy metal sliding sound. I have three concerns using that set up though, firstly it looks a bit Heath Robinson, angled bracket here, toothed ring bolted on, solitary bundle of wires coming forward (presently the engine electrics would finish at the forward pair of injectors and it looks very neat), secondly with not running any inner wheel arches the sensor will be rather exposed and protecting it will only add to the Heath Robinson look and thirdly the sensor fouls where I want to hide the alternator. I've got all the kit to do a crank pulley mounthed trigger wheel, wouldn't need to worry about machining as the alternator is going to be on a custom bracket and thats the only pulley I'll be needing driven.
