Training For the Bavarian Rallye

[Espennaess]

BTW, managed to crack the 400Hp, but now i'm struggling with the MTBF

[Espennaess]

Also it would be better to have a gradual pull, yes. With 265mm tires, the wheels would just spin every time you put your foot down

[Espennaess]

Just made another car which had a 101 more horsepower, better handling, and it's 0.01 seconds faster than my original car

[Der Bayer]

Build the engine from within the model designer and you get the actual MTBF with the car's cooling capability. Then you will see that you can easily get 400+ hp from an 1.8 liter engine (if you want to).

[Espennaess]

Worked great, Thanks.

[Junny]

Guys build your Engines for the car not by themselves in the engine builder, you will have alot more MTBF to play with than you think. My first test car has 4000rpm of usable Powerband after hitting full boost and pulled a 80 second flat on its maiden Airfield Run.

Perhaps Killrob could do a short Youtube video explaining why Torque and Powerband are important and how to setup a basic turbo for the newcomers?

Edit: Der Bayer beat me to it -.-

[SirStonelouse]

i'm looking forward to this rallye. mir first build is at around 450 hp and does 83.7 seconds on the airfield.

I've come up with this

Red wine was not a factor, I swear.

[Junny]

Not bad. Is it going to be rocket powered?

[Espennaess]

This is my design, Kinda inspired by a Ford Capri. Doesn't really look like a rally car, but i may change the design a bit

He did. Without in-depth turbo explanation, but you should get the idea of a good torque and power curve.

My current BRC 1100 prototype build is powered by a revised version of the 40-valve V8 that powered the '84 Group B, it makes 401HP, the top speed is going to be around 245-250 kph, it's got 1.23g handling and it can make a lap of the Airfield Track in 82 seconds, my Super 1000 isn't as good, it makes 128HP, the handling is barely 1.18g, the top speed is 190kph with nearly zero downforce, with +-100kg it drops to 160kph

[conan]

My Super 1000 car has 140hp, it is only 10.98 seconds off my 1100 around Stop Deer Test Track, with a little bit of downforce (Had to put in some underbody cladding so it doesn't produce lift) it makes 1.22g in the corner and it will top out at 204km/h. I still wouldn't put my money down though, there are amazing people out there who'll do it even better.

Oh and just so you all know, there are people who already have broken 500hp in the 1100 Class. While the average (with more useful powerband) tends to be at around 430-480hp. It's the difference between each machine that make this interesting. Different people use different way to solve problem and make rally car go faaaaast, it's not just about the power that matters.

[Reaper392]

I have kind of an odd problem with one of my cars. It has quite a peaky power band which means that it is as tame as a lion that has just trodden on some lego and that I probably wont use it, but for some reason when I make the individual gears bunch up even slightly closer to the final gear the 0-60 time will go down hugely because the tyres magically lose ~0.2g of acceleration grip during the start. It is not the poor low end power that is limiting the grip as you would have expected because the power line is well above the tyre grip in both cases.

Does anyone have any ideas on how to fix this, because with the gearbox bunched up at the low speeds the acceleration in the high speed is a lot worse than it should be.

[OCAdam]

Sounds to me like the driver is just smoking the tires massively and letting the power at the end do everything. Aaaaand then at high speed... there was no high speed. I'd suggest running gears that allow you to retain a good acceleration POST-launch.

To give some insight into my car... at least for Revision 38!
