AVUS Grosser Preis von Berlin 1991 [FINISHED, RESULT INSIDE]

Will we be able to see a simulated video of the race? Or will you just post the results when you’re done simulating the race?

Like last year, but more calculations and stats.

First of all the final entry list for the race on Sunday.

Well, here’s hoping I do well enough

[size=150]Presentation Day[/size]

Traditionally on the Saturday before the race there is a round with unranked cars by the host teams.

DMW Transeuropa

DMW used the track to test their Transeuropa 91 sportscar with front wheel drive. DMWs highly expensive and solid V8 Turbo delivers impressive performance and top speeds of up to 390,8 kmh but the FWDs were again not able to bring the full power on the road. The 2.85L C50 could almost catch up with the Turbo version after pit stops, gaining 4 minutes out of 6, and was only slightly behind at the finish line. This indicates that the turbo factor was nearly right this time and put N/As at least within striking distance, even though turbos still have a minimal edge.

Z-911P

In the C60 host race the DMWs faced a car from Czechoslovakia, the ZLIN Z-911P. We had invited teams from neighboring countries to use the track, and Czech enthusiasts from the town of Zlin have immediately jumped at the opportunity. While the Z-911P cannot match the Transeuropas top speed, it was less expensive, and demonstrated that cornering and acceration are also important on the AVUS. In the end the ZLIN clocked better lap and race time than the DMW, making it our fastest car to date.

Table 1 Presentation day results

This serves as a preview of the format in which we will present the results. The light blue area indicates the total race time after pit stops are added. From left you can also see the time for one lap, the track time without pit stops, number of pitstops, the total pit time and if there is a change in position, an indicator how much the car has changed position due to pitstops. In this case, none of the cars changed position but there have been quite substantial gains by the only N-A car in the field, the DMW 9128. The gain was 4 minutes but unfortunately it was ca 6 minutes behind in track time, otherwise it could have beaten the 9112 turbo.

Feel free to ask questions about the classification, because It could help me to improve the presentation of the result tomorrow.

Table 1 Presentation day car data

Here you see the usual information about the cars, see above.

As I wrote, feel free to ask questions to the classification, because it will be possible to make better explanation until tomorrow when the official race results are presented.

Ok so much for the reference cars. Times should be taken with a grain of salt, and in no way do I claim to have anything to do with respect to the real race. They were of course only possible because I had the full picture from the full race in 1990, especially how to approach the cost limit. The Host has of course a big advantage here, and you had to figure out your times all by yourself, that’s why hosts dont take part in any of the races. They only show what I more or less couldn’t say when people discussed the top speeds etc. Now the cat is out of the bag, I was able achieve 390 km/h in the C60 and 365 km/h in the C50, and both F-FWD and R-RWD could me made to run the fastest lap times.

I also had a 4 cylinder turbo which I couldn’t develop to its full potential, but it got pretty close. My tests showed that 4 cylinder, V6s and V8s all had potential, and that there are many different chassis which
stand a good chance. So I dont think we need to rule out any more chassis in the future. Oversquare engines are not a necessity although they do have an advantage in reliability. In the end it is a combination of many factors like maximum possible compressor size, block quality and performance index (which I consider to be some sort of integral over torque), but not only maximum hp or hp/kg.

Aerodynamics and cooling are key factors in the top speed ranking, but also transmission. Tyre width and weight to a lesser degree that I used to think. Hp are always good for more top speed which is important for lap time, but as you can see, a quick cornering, braking and accelerating car is much more important than you would expect.

I would only suggest we raise the turbo factor a tad higher, but again let’s see the race tomorrow. I am quite excited myself to see the result, because in the end there were several cars which got pretty good times, and with very different approaches.

Very good analysis. And I too am looking forward to the results tomorrow!

C50 results will be up soon.

One thing I know, next time conformance to a naming scheme will be a requirement :slight_smile: This is what costs me the most work right now figuring out which car actually belongs where.

Maam Vastra
Prydonian Motorsports entered the race with just 2800cc out of 2850, and a bit overweight. The performance index was actually quite respectable, so it is not clear if the car could not have done better.

**Slax **
Slax car was remarkable in that it was the only cat that came extremely close to 0 pit stops (1.07). This would have moved it up one position.

Boksi
Apparently Automurdermotive were invited to the utility car austellung at the Funkturm, but were erroneously sent the papers for the AVUS 1000km. The Icelanders so diligently fullfilled the requirements that they ended up with the fastest jeep in the world. They already received orders from German authorities for a truck that goes 300 km/h

Cadillac Dave
Nice lemon color! Chosen in Prollauto Magazin 2/91 as their favorite.

Deus ExMackia
The crowd cheered this beautiful retro car. It had some of the usual fitting problems that you would expect from a British product, but clocked excellent times. Interestingly AVUS Proto91 became the first “victim” of the pit stop rule. 4 pit stops meant losing a position to Leeroy Racing.
Unanimously elected as the most beautiful car.

HighOctaneLove
Leeroy Racing N/A car benefitted from the pit rule and moved one position up, taking a the 3rd podium position.
They also submitted a turbo, but something must have been wrong with that engine, because it finished even below the trukkari.

OleBoresParabol
This car was a surprise that came from nowhere. An extremely good time for a naturally aspirated car, it took second place easily and was close to skipping another pitstop (2.06) , so it could have finished even better.

Markus 817
Matoyama Motors already demonstrated in 1990 that their engine and cars can always be expected in the top positions. Unsurprisingly they took the win in a race that was mostly consisting of new teams. The XSR-2 was dubbed “Das Japanische Ei“ because of its chubby look.

Here the official result for C50 class.

With only 8L/100km Madam Vastra’s Exigence was the second car that came close to 0 pitstops (1.06)

Needle Production Cars/Guardian Developmental Group are doggedly working on their dream of becoming a renowned team in the AVUS racing. And although their last entries were a bit unsuccessul their determination has payed off. The “Matte menace” car is 50 seconds faster than last year’s car, a monster improvement. Even though it was still not enough for a top position the Matte Menace does well in the field, beaten by just seconds. By the way, our specialists saw several things how the Matte menace could be even further improved. For example we would reconsider AWD, only RON 92 from 98 octance fuel or a super aggressive stroke of 85.5 x 84.6 that made the creak even under modest stress.

Cadillac Dave
Nice lemon color! The cars will be featured in Prollauto Magazin 2/91on next Monday.

Squidhead
The Nardo was interesting because it has the lowest fuel consumption for any turbo in both classes (only 2 pit stops) and got very good laptimes, but in the end several N/As were better. Perhaps the fuel consumption was a gamble that didn’t pay off, otherwise we had expected a better position until we saw the ultimate result. Still, a good 6th place.

HighOctaneLove
HighOctaneLove entered with a V12 (even transversely mounted!) that got dangerously close to OleBoresParabol’s SuperFang. In the end they were only 30 seconds short of taking the 4th place!

They also submitted a turbo, but the same picture emerged like in the C50. The NA was very competitivie but somehow the turbo couldn’t quite impress.

OleBoresParabol
Fenris already got a great result in the C50 earlier today and the C60 Superfang showed that it had not been a fluke. With one of the best times for a naturally aspirated car they took 4th place. The Superfang lost out a bit on pitstops (2.11), otherwise the distance to Place 3 would have been merely 9 seconds.

AirJordan
This car is a bit of a shock. Nicknamed the “Evil pumpkin”, Smooth Racing went the radical route, with reduced air resistance and an absolute top speed 381,0 km/h, in spite of considerable extra weight. Ultimately they had to pay a price for the excessive weight (1117 kg) but could defend 3rd place against Superfang, which had been directly at their heels over the whole race.

Markus 817
Matoyama Motor’s cars were again the force to beat. Interesting is the switch of position between their two cars, the XSR-2 Turbo, which drove the absolute fastest lap time, and the XSR-2B N/A. A bit surprisingly it was the XSR-2B that won the by a race razor thin 10,31 seconds after the Turbo had completed 4 pit stops and fell back a total of 6 minutes (without pit stops the lead of the turbo had been 5m49,69).

**Congratulations to the Podium: 1-2 winner Markus 817, and AirJordan with its amazing “Pumpkin”. P.S. We really like radical stuff!! **

[size=150]Result / C60 Class[/size]

Here the official result for C60 class.

Hell yeah! 4th place. Excellent commentary @BurningBridges too!

Yeah, Congratulations. I believe it was the air resistance that killed your fuel consumption, otherwise you could have made place 3 too.

I hope you all check the results more closely, there could be some mistakes. The pit stop rule actually made a bit of a difference but not too much and I am very happy with it.

Also, one class was won by a N/A and one by a turbo, so it was really a pretty well balanced formula. I still suggest a slightly higher turbo factor of 2.4 to 2.5 for the future, in light of the absolutely best cars, which were still turbos.

Midfield…huh :\

I believe you were also a bit at a disadvantage with your choice of chassis, also the fuel strategy did not really work well for your turbo.
That means lap time was not quick enough for a turbo, in spite of a good strategy,

I did miles better than last time!

The Matte Menace!!!

Yes, but also check again my tips. Your car could have gone even quite a bit faster actually.
