solid flywheel on an engine designed to work with DMF (no torsional vibration dampeners) will cause more wear on the bearings and if you are very unlucky it might even snap the crankshaft.

So If I replace the F40's gearbox on a 2.4 Brera with a dampened performance clutch with a Single Mass Flywheel, I get all the pros of a DMF but without the penalties?

Normally engines with solid flywheel have a harmonic vibration dampening pulley at one and end then flywheel at the other end with dampened clutch.

If you want a solid flywheel then you need the harmonic dampener to protect the engine and crankshaft and then dampened clutch to protect the gearbox.

Some manufacturers during early days of DMF flywheels used to do official kits for SMF conversion and that's exactly what they included: crankshaft pulley, SMF and a clutch.

Doing it any other way will sooner or later break the crankshaft, especially on a remapped engine.

So lets say, would one from a 166 2.4 do the job?

Also, my mechanic services a lot of vans and says that it's very common to get a coversion kit from the clutch manufacturers that has a clutch and an SMF for them. Lowers the TCO on very high mileage fleets.
Don't know if one is available for this engine though.

Just looked agsin if you go for a solid cg flywheel need to get the stage 3 clutch kit which comes with sprung drive plate

Words from the site

Where applicable we have 'dished'; the flywheel so it can take the cage of our sprung drive plate. Ensuring the dampening effect of the standard Dual Mass Flywheel can be transferred to the sprung drive plate found in CG Motorsports Stage 3 Kits.

I've got the CG stage 2 on my 147 and it handles the extra power and still feels like the standard clutch, depends what tuning you have in mind though?

Hey Ed you still running a DMF? Or gone single I'm looking mid range power anything up 250hp and 350 torque maybe higher but this will still be work in progress was going to go for CG stage 3 with SMF but not sure if it be a over kill although tuning on the 147 will be a slow process as I'm still building my track toy

The clutch is slipping when putting power down in 4th gear and up so I need to make my decision pretty soon

I still have the DMF as I didnt want to make it too lairy as the mrs drives it most of the time, dont get any slip or anything up till now on the stage 2, but if you have bigger plans stage 3 may be the way to go.

Around 204 at the last dyno run, may change my mind about the clutch in the next week or so when I get new tweaks sorted.

No idea on the book time, took me a weekend but also fitted a Quaife and Eibach ARB.

And only had the mrs to help me get the gearbox back in (and she had just had her nails painted) and I am a bit of a cleaning/paint everything fanatic so reckon you could do it on the drive (same as me) in a day if you just went for it.

Standard clutch on an M32 or F40 box 1.9cdti Vauxhall should hold 370lbft and any power that falls under that ([email protected]). Do the Alfa clutches struggle below that?
