It's much worse than you might think

The deformation is stock, look at my first pictures in this thread. And anyway the car body should be strong enough to work and to not crack. That's the goal of this thread, to make people realize how weak are these cars, they'd better check their cars.

These are pictures of a Cup. Both sides were cracked, unfortunately the workshop didn't take time to take more pictures before the repair. This car didn't go to the track. This pannel is 0.9mm thick This is the 1.2mm pannel in front of the right turbo. The curved wall that was cracked the...

Nothing is adjustable on the front of any biturbo (let's put aside Open Cup). The rear is partially adjustable on Abs and GT (and thus Cup), don't know how much. There is a rear adjustment on pre-abs but it's more alignment, not performance. Why don't we have technical anwers from the Cup...

I don't know what should be on a GT. Btw, if you want a quick GT you can install a ZF from an automatic QP4/3200, they got 3.95 diffs.

Looks real ! Except for the start from 0, the turbo lag and lack of torque below 3000 would make it much slower.

Well that's not fair (and illegal). The author spent months working on this book (many of us know him) and he does not earn much on every item. The book is not expensive.

No idea. The car came from Italy and was owned by at least 2 persons. Then bought buy a French, then by me (1400km later). However I know a very skilled maserati workshop. The guy repaired tens of biturbo of all ages (from carbs to qp4) and has never seen cracks ahead the engine frame.

What's the Cup final drive ratio ? On my GT there is a huge stamp 3.45. I still need to check if it's true

On my GT 2.0 it's 17.3mm front 13.5mm rear. With painting of course. For the rev limiter on 2.8 I guess the soft one is at 6300, the hard cut 6500. I will check if I have the tunerpro config for these eproms.

It will and it did break again on my car: lots of cracks around old welds. As I said the entire structure must be reinforced, including the firewall and the floor. There are sheets of metal to be added, all the empty structures have to be opened, some sheets of metal must be replaced with...

Looks realistic. I've just realized: it's a 2.8 engine model, right ? Does Cup rev up to 7000rpm ? All other 2.8 were rev limited at 6300. Ps: the friend does not have suspension data for ghibli. Only ghibli engine and electric stuff manuals. Btw, do you know the thinkness of the Cup antiroll...

So you are basically saying that it's impossible to analyze phenomena or objects if you don't personnally take part of them ? Engineers can't analyze structures if they are not on the bridge when it breaks, transmission quality can't be qualified if you don't call from the exact place with your...

Then contact me in case I'm here in august

The front antirol is not stiff. I don't think Cup had a stiffer one. To me it does not make sense to have stiff front springs and soft antiroll on sport cars. It should be the opposite. But they did this way. The rear antirol is soft on all biturbo (means racing, 222 4v and all ghibli/qp4). I...

I'm near Grenoble, in case you need help in France

Looks much more realistic: both engine response and suspension. For the body roll a x1.5-2 speed playback is handy. Would be interesting to try on a slower track with tight left-right turn passages. And a run with accelerations starting from 3000rpm.

I've already mentioned this in the other thread. These pictures show how approximative was the body assembly on my '97 GT (never seen such a poor quality on older biturbo cars). The small bar on the right of this picture (that is usually smashed because idiots try to lift cars here) was not...

I did that because the engine was out (dead 1400km after a rebuild by a french "specialist", so I'm building a new engine. I bought the because of the engine problems so I drove it on 50 meters). But I knew about these problems, I did my red car 2 years ago, and I have a collection of photos of...

Btw, in the bottom part of this picture, just where the black putty starts on the frame there is a rectangle mark. It's a hole in the metal sheet that was used on biturbo cars to hold the torsion bar. Then starting from ghibli the bar was mounted behind the engine. But the hole remained because...
