147 jtd 16v flywheel

Hello fellow Alfa enthusiasts,

I'm completely new to this forum, so you'll have to be a bit patient with me while I'm getting to understand how things work, but I hope someone can help me with one of the very few things that bother me with this otherwise fantastic car...the clutch/flywheel.

My car is chiptuned and it appears the standard flywheel cannot handle the extra torque very well, resulting in nasty vibrations as soon as the turbo kicks in around 2,000rpm.

I replaced the whole clutch + flywheel at around 85k (50k miles), which helped...for about a week.
A very expensive and very useless exercise therefor.

Next step was a visit to the chiptuner (the best one out there - Squadra-tuning), who lowered the torque output in the problem area a bit, but as I didn't want to go down on torque too much (it made the car feel sooo slow, now that I was used to it!), it improved the situation only slightly.

Now my question : does anybody know of any stronger clutches / flywheels on the market, that will be able to cope with the extra torque ? And what would that cost me ? As I'm thinking of upgrading the turbo as well over time, I'm looking for something that can handle 400-450nm without breaking a sweat.

Any useful tips and idea's are very welcome...thanks everybody !

Hello and welcome - hope you get sorted out quickly!

Thanks for the warm welcome and the tip to visit the tech section guys !

Welcome to AO

zbrskz (member on here in Portugal) is running 480Nm in a 1.9 JTD with hybrid turbo, try sending him a message.

I get flywheel shudder in my 2.4 JTD if I drop the accelerator at 2,000rpm in 4th or 5th - my solution is to drop a gear, to bring the revs to 2,500-3,000 before I put my foot down. Heavy in first gear gives it a bit too, but its never done any harm in 35,000 miles. At the last clutch change the DMF was in perfect condition, on its original at 122K miles. This is a remapped 2.4, torque around 420Nm or so.

welcome to AO...

all the best

Hello and welcome

Thanks Pud237, this is exactly what I experience and I do the same to avoid it...shift down one gear. Unfortunately, the powerband of the 1.9jtd 16v is not that wide, so 'loosing' this 500rpm in the rev range where the car is the strongest, can make the difference between barely keeping up with another (fast) car or giving it's driver a really bad day. ;-)) After I had it de-tuned, I really felt the difference, so getting a stronger clutch/DMF and perhaps a hybrid turbo (I see quite a few people here on the forum running these...) could turn the car really into something special. I'll follow up on your advice and will try to contact 'zbrskz'...perhaps he's got a few pointers for me. Thanks again !

Hello and Welcome !!

moved to tuning and upgrades

When I had my 8v JTD I had to replace the clutch after the Angel remap. At the time I had looked into it on the forum and some members talked about replacing the dual mass flywheel with a conventional unit, which would also be less expensive. The dual mass flywheel is there to help smooth the transmission with the large amounts of torque.

Thanks everybody ! It's really great to see so many friendly replies, I've seen people interact differently (less friendly) on other forums...

As for my flywheel problem, I wonder what Alfa is using themselves on their 'Ducati 170hp' version...Unfortunately this version is not gonna find it's way into the Dutch Market, so the dealership was not able to give me any details on it, but I cannot imagine that Alfa is using the exact same spec flywheel as on the 140hp/150hp version.

If they're indeed using a stronger version in the Ducati version, this would probably be fitting my 140hp as well, right ? This would be my best option then I guess.

Does anybody have more info on this, or any good ideas where I might be able to get this information from (the web) ?

Thanks again.
