BRC QuER - Hockenheim 1000 km 1976 [FINISHED]

Finishing up testing for today. Just broke the 2:25.00 barrier with 508 bhp.

I have build a turbocar and yes, great success it’s faster than my NA… but… sigh …it needs 3 tanks of fuel to finish 20 laps… not ideal one might say :laughing:

I’m now very torn apart. I got this wing that makes my car look like a BMW M1 Procar, but it’s actually hurting laptimes :frowning:

I know right! Just put aero to 0, no harm there…

Actually there is a difference, even if you are going for 0 degrees. Also this concludes a completely automationed sunday, with the most viable result being… unsatisfactory.

Ok, seeing people’s horsepower numbers… how??? Are these like massive 6L V8s? Made a 4l V8 NA and was finally able to see 460 HP, but the power band is awful. Turbo V6 is currently my best engine, but its hard getting much more than 360 HP from it due to size and money limits.

Finally passed the 2:24 mark, but the thing has effectively 0 driveability and grip…

Soon.

Just finished testing today as well. Ran high 2:17s around ATT wth 357 hp. That good?

not really comparable, the race track is a faster and less corner-y track.
my 2:15 on the ATT came out 2:26 on the race track

i just could NOT find turbo setups to be advantageus, brought the NA one down to 2:25, but i cant bring the turbos lower than 2:26,5

Bob, how awful is the powerband? I am running exactly the similar engine setup by the looks of it, but it’s pretty good up top, even though I’m running quite a bit less CC

I’m pretty happy with how it’s going so far. I know I can’t compare the 2 directly, but, my laptop’s being stupid right now, so I can’t download it for myself yet. I just wanted an opinion on something. I have a more conservative suspension setup right now, but because of it, my drivability and sportiness are almost exactly even. And it still handles decently. But, if I use a more aggressive setup at the expense of some drivability, would that be better?

Well, the tracks are completely uncomparable. Hockenheim needs a fine ballance between power and top speed and cornering ability. I dropped 3 seconds off the initial lap time just by fiddling with the aero and the suspension, and it all lost me quite a bit of time on ATT. The initial ATT time was 2:09 though, if that’s what you’re asking, but I do not think that’s a factor. The drivability. Well… With these seriously unrestricted rules I am guessing most people will have trouble getting their drivability over 10 with track sportiness ranging from 30 and up. The ideal ballance is ā€œdrivability over track sportinessā€, but I honestly do not know how to do that.

Also, Bob, I ran 1100 hp and all it did was never put it all to the ground. As in ā€œActually neverā€, even at speeds of over 250kph the car was at best at 30-40% throttle, so yeah, power numbers aren’t very informative. Also note that the main limiting factor for everybody this time will be the tires. Even though the width is set at a pretty decent 265 you got 2 problems. 1. It’s nowhere near enough to handle some of the outputs we can muster up and 2. Since the quality of those must be 0, we are stuck with downsizing the rims, leaving less space for brakes, which ruins drivability. I will be running my NA with some 460+hp

The only body I could find that works around this is the muscle car, it has plenty of roof for wide tires and high profile, so you don’t need to limit your brake size, but that thing is ENORMOUS, it would need a collosal engine to pull it and it’s weight would get in the way of teh 3rd sector, negating the tire width advantage. If anything I’m running 235 (I think, too many experiments and too lazy to open up automation), and it’s pretty much enough traction at speeds over 120, whch suits me just fine.

I figured. My drivability is about 36.5 versus 37 sportiness atm. I purposefully did a conservative engine tune for that reason. I’m definitely not tweaking that too much.

Either it’s a brilliant design, or it’s not fast enough for Hockenheim. Download that track and start running your car there, then you’ll know for sure.

My car achieve 2:20.96 on race track with 4500cc 500hp engine.

P.S. after some tuning up, my car break 2:20 wall.

I guess its not THAT bad, but compared to the near flat power bands I strive for, its very peaky. Current iteration is a reliable 3333 cc V8.

My two cars are entered, will upload pics later in the week

I do not see a problem here. :slight_smile:

The smaller fuel tank’s a joke. A brc66 nine stop turns into a '76 14 stopper.

My fastest car is looking at 22 stops!

Is that a turbo? Because I don’t know how to get there.

Smaller fuel tank? 10 kg/m^2 in 1976 instead of 7 kg/m^2 in 1966 is significantly more.
