AVUS Grosser Preis von Berlin (1990) [FINISHED]

[BurningBridges]

No, not as far as i am concerned

[BurningBridges]

I will not change anything now since there have been the first entries.

But some things I found while playing with my own concept car, there should be new rules for the next race

1. Minimum Engine Cooling = Cooling required
This is simply, because cooling has an immense influence on the lap time, and I dont want the winner be decided by the cooling slider.

2. What about turbos? First everyone demanded a handicap factor of 2:1, now everyone seems to enter with a N/A Mission accomplished?
I tried a inline 4 turbo and ended up with barely 30% less hp than while being more heavy and unreliable.
If there is no evidence that a 1000cc turbo can even compete with the 2L engines, the handicap factor will be adjusted for the next race.

I suggest that everyone who wants to enter a larger turbo can, and will be run on their own.
At least that's what I am gonna do, build a 1250 turbo to see if it can beat my NA car.

I would suggest 1250 cc as opposed to 1000. Thats a handicap of 1:1.6 instead of 1:2
This can be made use for very even numbers, the classes could be:

Have a look at Group B mate. The ratio is around 1.7/1 and seemed to be optimal.

[BurningBridges]

Sounds all right.
Perhaps 1.666... that's better to calculate.

The ability to simply upscale engines is gone either way, perhaps thats even better.

[YugoSpy]

Are sports compound tires allowed or is it just hard long life tires?

[BurningBridges]

Everything is allowed except semi slicks, and all quality sliders can be changed except one (tyres).

[BurningBridges]

Group B is different and the handicap factor is so low that we would go back to where I started (I had 1:1.5 initially)

How about this for classes? The advantage is that the handicap rises for the larger engines.

hmm. i actually find the 1l vs 2l is rather ok.

im getting roughly the same peak output but much lower drivability, but also lighter engine with turbo, and vice versa with NA

[BurningBridges]

I will listen, but only if you send me the first 1L Turbo car that is competitive

So far everyone has just said Turbos should be penalized. So far I am unconvinced. Even with 0 reliability my own turbo is 30% weaker, the 2L car can go circles around it.

Same here!

[Sebesseg]

Yeah I'm getting a better performance index number (and by extension more HP) out of the turbo engine I'm running. Its taking a HUGE hit to driveability. Right now, I can't say how competitive mine is b/c I'm not really sure what is competitive.

I'm going to build using a smaller body for comparison to my probable entry since I want my company's PPX car to the 90s "race" car (as in both the high end production based races and non-production races, etc) though I'll have to amend its history b/c its one year too late right now. So it'd be a near-production ready prototype (engine swap and weight-saving measures deployed to be competitive and within regulations) for this competition.

[BurningBridges]

No problem, this is not meant as a dead serious competition, where only winning matters. I hope to see turbos no matter what, but the rule is not going to change again. Only for the next race there could be a new formula.

It's meant as a gathering of carmakers to see how more can be squeezed out of the same technology. Like, can you make a car exceeds 300 km/h, 325 km/h, 350 km/h etc? That kind of thing. I'm using my experience for a production model, and I already learned a lot. If I can realize all my ideas it could be a sensational car imo.

[BurningBridges]

I have an important question though.

Cooling requirement is merely a function of horsepower? I thought it's important because otherwise a car with low cooling requirement could make up for horsepower (cooling costs a lot of speed)

[07CobaltGirl]

Here's a turbo 1.0L for you.






***NOTE - This is not my entry submission, but my submission will be a turbo.**

[strop]

While more HP tends to more cooling the relationship is not at all proportional. Other factors include how rich the fuel runs, how much boost on the turbo there is, layout of the engine, and the tech year (cooling efficiency improves over time). So turbos running aggressive boost tend to require a LOT more cooling than the NA engines with the same output.
