That was quick! Dont know where I would begin looking!
it broke again :(
I need hints, what could be the cause. Material fatigue ? What do you guys think, have anybody here had similar problems ?
also I'm in a desperate need of a diff. Some gears would help me too, if you have a broken diff laying around.
Something is not right at the back to break two diffs! Will have a think...
Prop out of balance???
Dunno...

Is there much vibration from the car you think when driving?
I think the Dedra Integrale's is the same, don't know about Bulgaria, but here there's a whole bunch of them for low price, as opposed to Alfas.
My guess would be that there's something wrong with the torque distribution. Did you, by any chance, drive the car without the prop-shaft on?
there was vibration yes ...
a have not driven the car without prop, however I had to pull it once for over 130km with the prop disconnected (the car rolling on its rear wheels)
Can you post up some pics? It's no good just guessing without seeing what the diff looks like from the outside and what damage has occured (presumably) internally
1st - sorry for my english
Inside the diff it's the torsen part that brakes - the small helical gears in it. they are like cut in the middle with a knife. I will try to make some pics of the broken parts.
one more thing. I saw on the eper that the price for a new 156 Q4 rear torsen (the torsen part only) is not quite expensive (~250 euros)
Does anybody have any details about it ?
Disregard my comment about driving without the propshaft, that could hurt the central diff I think...
I'll have to read more carefully next time, sorry.
Don't worry about your English, for sure it's better then my Bulgarian.
I wanted to know if your diff was like an integrales, I doubt it is as they are pretty bombproof.
How are you breaking it? Are you launching the car suddenly like in a drag race? This is what breaks transmissions, not outright power at these levels.
I launch carefully. Especially with the second diff, I was very careful, actually it almost haven't been launched at all. There where however vibrations form the rear of the car with it.
We were not able to open it prior to putting it on the car, because of the "warranty" they gave me. It was sealed and I had a couple of days money back warranty if it was not in good condition. We only changed the oil in it and put it on the car. I will for sure not want a warranty diff next time :D
I just bought a dedra rear diff. It is an open diff with el. blocking via a solenoid. The housing is almost the same, and it fits without any modifications.
I drove it for a test, and its OK. Haven't tried it on a track or launch however.
Later I will probably try to connect the blocking device somehow (it works needs vacuum and some kind of control of the solenoid)
If someone has more info on it, please let me know.
Meanwhile, I sound dampened the hole car, replaced everything on the brake system and installed new seats. I have to say it became a different car. Will post pics later. Time for bigger injectors, 3 bar MAP and some serious tuning finally .... :)
I'm assuming its not finished yet, :biggrin: and are you going to be fitting an external wastegate? That first pic looks like you have closed off the one in the turbo itself.
Great work going on there. Can you tell us what are your plans for the car, are you using it on the street or just on the track. ps.. nice welding.
JimN~
Almost done
It's quite tricky with the space this car :(

thats looking very good J
j1v, congrats. Nice and dedicated job.
I have to admit that I'm glad I have where to learn from. What a forum, what people !
Thanks for the share.
Regards,
Chris.
Nice, I know how a normal wastegate works, no idea on the external, will have to read up now :deal:
A dyno from the last month, stock exhaust collector, internal gate 1.6 overboost, 1.3 hold :

And a dyno from today, the new collector, external gate, 1.9 bar hold boost:

Finally time for the rest of the car to be done (body/suspension/brakes) :)
Very impressive!

yes, it is very impressive. I read back over this whole thread today - its great to have those pics so that we can really see what you are doing. But there is one aspect that I don't understand. How did you remap the ecu. have you purchased a premade chip - or have you made one yourself with an eprom burner / rom emulator etc. If its a "home brew" one - did you find that the info on this forum is correct regarding the table mappings / values? which tables did you change?
Thanks, JimN.
Nice work keep it up
Yes, lancia VIS stock cams. I took the info from a pdf found somwhere, and also measured them to be 100% sure.

Thank you. You've got PM.
Very nice job. I must ask, are the dyno plots wheel power/torque or flywheel power/torque?
/A
I don't know if I'm gone mad, or what but ... it's time for stage 3 :)
1. Bigger intercooler (again), 600x300x100mm core :)
2. Garrett GT3076, .63 A/R
3. Eaton m62 from c230 kompressor :)
4. A pretty simple and effective schema to make ... just need time, luck and a lot of patience.
5. Dual stage water injection 50/50 water/methanol
6. 10mm fuel lines
7. bigger custom SS fuel rail
8. Planned boost - ~0.8 bar off idle, up to 2 bars at 4500k all the way to the rev limit (8k)
9. Planned power - about 450 - 500 :)
BTW, I have just swapped to a Lancia Kappa turbo intake and I must say I love it. This is the best intake for this car. Will post pics soon.
Here comes the summer ... time to think about underhood temps :)

wicked. Are the VIS cams still inside?
