Wolfgang sent me some pics last night, but I'll wait for him to add them to the garage.
If you've not made the connection yet, this was Wolfgangs last car: 155 Q4 racecar

**mpampis_** · 10-05-12, 11:53

I would prefer this Q4 more than Monica bellucci!!! Amazing car

**Steve Webb** · 10-05-12, 20:35

That looks like a really well prepared race car. Although there appear to be a couple of things missing in the last pic.

**Wolfgang** · 10-05-12, 20:59

Hi Steve !
What do you mean with missing parts, ... the exhaust ?!
It´s coming out directly under the drivers door hi hi hi !

I know what you mean, ... the axles, this picture was made when I have installed the new rear sway bar.

Yep the rear drive shafts. Are you using standard ones or something a little more heavy duty?

I bet the car sounds good with that side exit exhaust!

**Wolfgang** · 10-05-12, 21:33

Yes the sound is like a hymn, ...

I use normal drive shafts the power and tourque is not that high that they will make troubles, just the rubber boots are special once they are stronger, I´ve got them from Denmark from teamcompetizione (Mende Trajkovsky).

Exact power I don´t know but it should be arround 260 Horse Power.

**JBSOUND** · 11-05-12, 01:16

Amazing car, the 75 is my dream car and to have a 3.0 specially for racing is great. Congrats!

**Steve Webb** · 11-05-12, 16:32

just been looking at the RSR site for the roll bars, are yours the 30mm front / 26mm rear?

How do you find them?

At those sizes I guess they are full on racing spec.

**Xti** · 11-05-12, 16:49

Mmmmaaaammmma miaaa!!! I've always knew you will come with something strong. Great result! Very good looking body , what more to mention about tech side.

Btw, I miss that garage of yours and sometimes I was asking myself if you still have it.

Congrats, Wolfgang!

Greatings from Cristian.

**Wolfgang** · 11-05-12, 19:27

Good Evening Everybody !

Yes Steve, front sway bar is 30mm and rear is 26mm and I can tell you the handling of the car is like hell

! The transaxle cars have a perfect weight balance and together with a good suspension and sway bars ... unbeliveable good.

I think the handling is much better than the handling of my race 155 Q4 was, especially on the rear side.

I also bought the brake upgrade from Ron Simons but I think he do not produce this kit any more.

I try to do every project perfect and not only just to have such a car and it´s good enough when it´s working 50%, ... no it must be better than 100%.

**Wolfgang** · 11-05-12, 19:28

Thank you very much for your gratulations JBSOUND !!!

**David ARTC-215** · 20-06-12, 13:13

It's spectacular! Are there any video where you can see running?

**Wolfgang** · 24-07-12, 10:46

Hi Everybody at the Forum !

I´ve uploaded my first VIDEO of the 75 race car, if you´re interested please see [ame="http://www.youtube.com/watch?v=aCJCYxKFKkU"]Pannoniaring Young-Timer Alfa Romeo 75 3.0 V6 Wolfgang Zillinger - YouTube[/ame]

Many greetings to all of you !
Wolfgang

**David ARTC-215** · 24-07-12, 12:21

Spectacular! It's amazing his Alfa 75! Congratulations.

**Xti** · 14-08-12, 12:52

What a beast, must be such a good feeling

it . How much does it go on revs? Congrats and good luck on competitions!

Greatings,
Cris.

**Steve Webb** · 15-08-12, 10:24

Looking good in that video Wolfgang, you seemed to be getting quicker throughout the session.
Is there much development to do on the car?

**Wolfgang** · 16-08-12, 07:39

Good Morning Guys !
@Cris: Max. Rev´s are 7.760 U/min which is very high for a 2-Valve engine !
I´ve finished on 4th place in the first race and 3rd place in the second race on the last event on the Slovakia-Ring near Bratislava.

@Steve: Yes, that´s true, I´m getting quicker the longer the race was, I´m still learning how to drive that great race car on the limit because there are some major differences to a normal modern street car like no brake servo unit, no power steering (and that´s really hard work with Slicks 240/600/16 tires)

I can only say once again, ... driving that race 75 race car with some suspension parts from RSR is really amazing !!! It makes so much fun and you can control the car perfectly.

I still have to improve the front brakes and must find later brake points but better brake points will come with more driving and driving and driving and this should be no problem because there is no work to do during the races. The car works brilliant without any problems.

Of course there are some points to improve during winter time like:

1) Change the position of gearshift leaver (I´m working on it right now), I will change also the position of the gear shift linkage from outside to inside.

2) Bigger water cooler (had 107 °C water during last race, outside temp. was 39 °C)

3) Change the position of the steering wheel, within the original adjustment it´s still like an "Autobus"

4) Need two new shocks on the front axle

5) Prop shaft will be special made from Carbon with a cardan joint in the back, sliding piece in the middle and only one big donat on the front side from the BMW 850i

This should be enough work during winter time, ... for the future I´ve planed to install a throttle body kit made by AH Motorsports and a custom programable injection-ignition system.

Of course a 3,0 V6 24V engine will have more potential, but do to regulations I have to go with the 2 valve engine.

O.K. that´s it for now, I wish you all a very nice day
Wolfgang

Wolfgang

Were the brakes still a little cold when you locked a wheel up and ran wide into the second right hander? Or were you carrying too much speed after overtaking that blue Japanese car?

Steve

**Wolfgang** · 17-08-12, 08:35

No Steve, I just have made a shifting mistake because of the bad position of the gear shifter, found the 5th gear instead of 3rd gear and then engine brake was missing to reduce more speed and I had to brake harder. Finaly that was reason for locking up one wheel (it was on the rear axle right side)

Greetings
Wolfgang

**Steve Webb** · 17-08-12, 08:45

Ahh, that makes sense. The 75/GTV gear shift is not the best in the world is it? I think most road tests of the car have the shift quality down as a minus point of the car.

**Wolfgang** · 20-08-12, 08:21

Good Morning Steve !
Yes that´s true, as I have written in my last post, I´m working on an "Inside gear shift linkage" with a self made gearshift lever. I´ve made some pictures and in one you can see the old gearshift lever which is still in the car to see the big difference to the new one. I will screw on the new gearshift console so I can remove it if I need the space to work in the car. I´ve seen cars where the console was welded into the car, I think screw on is a better solution.
I will upload new pictures. There you can see my start of the console construction with the new lever. Still to do is the new gearshift linkage to the gearbox through the floor panel.

Have a very nice day and many greetings from Austria
Wolfgang

**Steve Webb** · 20-08-12, 20:59

That looks like it puts the gear shift in a much better place. How are you getting the linkage out to the front of the gearbox?

Also is that a brake bias and line lock behind the gearshift?

**Wolfgang** · 21-08-12, 04:36

Good Morning Steve !

You´re right, behind the gearshift I´ve a valve to block the rear brakes, it´s like a hydraulic handbrake just to fix the car.
The second valve I need to adjust the rear brake power.

As I have written in my last post the gearshift linkage will be going parallel to the cardan tunnel inside and right in front of the gearbox I will drill a hole in the floor panel to bring out the linkage onto the gearbox.

Many greetings to you Steve
Wolfgang
