[quote=“Denta”]i dont see big block V8 are viable option for now, yes it can reach 2:24 and 294 km/h on stat but suspension tuning doesnt really help, aero only make it worse, and my car barely have any grip at low speed and im not using turbo plus the 50%++ wheelspin which i dont like it considering its gonna rain. MR does help the wheel spin very well but there no body shell that can have big size V8 with turbo, still not counting the estimated fuel economy yet :confused:

either i tune the engine wrong or im not found the right powerband/engine size[/quote]

I disagree, even though I understand your predicament. Atm my fastest NA car is one featuring a 10,5L V8 doing sub 2.21 laps, with further tweaking I am hoping to get it below the 2.20 mark which currently seems possible. But you might want to think outside the box regarding which bodies you are using? And wheelspin tends to be an issue if you want cars with enough power to do 300+ kph :smiley:

162

What about actual drivability of the car? You get wheelspin every single time you sneeze at the throttle pedal and I’m pretty sure you’ll be getting a lot of driver errors. And if the rain starts you won’t be able to use any power at all.

163

I’m now very curious as to what kind of fuel consumptions people are getting. I haven’t had the time to use the Packbat-o-mator, unfortunately. I just get this sneaking suspicion that I’m being even more conservative than I think I am…

164

I can’t wait to see all those lap times you guys are pulling to make a stop every other lap worth it :stuck_out_tongue:

Agreed. I’m running with a 5.3 V8FP (which by the sounds of it is more of a mid ranged size engine in this competition despite how big it is) and I’m getting just over 2:23 a lap. Wheel spin is still a little bit squirrelly at 26%, but it is manageable. Only trouble is my top speed, which is 176 mph (so roughly 285 kmh), which I think is my biggest limiting factor. That said, my weight balance isn’t too bad, and I don’t want to upset that with a bigger engine. I have used aero, but not hugely. Most of it is for styling :smiley:

I’m beginning to think the two most important factors in this competition are power and weight. For more power, you need more displacement and hence more weight, which is bad for cornering but great for top speed. If you go for less weight, you have to work with less power and a lower top speed, but much better handling and improved economy.
Either way, it’s going to be great to see the video of the race. The main battle is going to be between cars that do great on the straights and can’t corner so well, and those that are slower on the straights and are brilliant through the corners. However, I haven’t the slightest clue which one will be better overall, as of course there’s everything else to factor in…
…which is why this is going to be such a good race.

Speaking of which, @DerBayer, how will we be watching this race? Livestream? YouTube video? Interpretive Dance? Text-based adventure game?

166

Novel? Comic strip? Tell Tale Games quest style? Artists’ rendition? Hand symbols?
:smiley:

167

Live Action Role Play?

On a more serious note it seems my car is fairly similar in spec with Deus Ex Mackia’s. Except I threw mine together in a hurry, so let’s just see how it stacks up in the pre-season. It’s only 20 laps though.

Crashing and safety and all that is still applicable here? Because if it is… I’m going to need to reconsider my strategy of taking out all the safety…

168

I will probably make the video offline in real time (speeding up might be difficult with many cars) with auto-scroll of the data enabled. Then I will speed it up in postprocessing so that the race takes about 1-1.5 hours to watch (x4 - x6). Then I have not decided if we make a commented stream of the race or just an uncommented YouTube video.

Safety and crashes still are there but it will be more difficult to DNF :wink:

169

Stats are:
Drivability: 20
sportiness: 42,2
Engine reliability: 25,2
Approx fuel consumption: 240kg/h
Fuel tank size: 86kg

Pitstop every 8 laps, and fresh tires to boot, but probably not worth it, with long refueling times as well. Interesting to se the comparison though :slight_smile:

Good to hear. Here’s hoping we’ll both be competitive against each other.

Thank goodness for that!

well tried it, it help a lot. thanks

i do say the wheelspin aren’t worth the long race since we aren’t chasing fastest single lap with all possible way

im very affraid about BRC RNG especially if your car have bad D/S ratio + the rain, hell even using the Turbo itslef pretty much gambling with big driver error i do say

with Hockenheim power fever pretty sure anyone in here will jump to big block engine party(and with turbo of they want early power kick) for straight line speed, and big engine surely wont be really good with fuel economy considering you wont run your car on peak power all time and valve float issue in big cam engine will ruin the fuel economy in top RPM. except you have very smooth curve which mean you spending extra money on valve

well trying 6L V8 and even more but doesnt give me sastifying result with the wheelspin and time result, i’ve got 44F/56R weight ratio but hell the number and graph doesnt convince me to stay with that approach

and i think im using same body shell as your previous posted car but somewhat got around 62% with the 6L

then i should be more agressive on my suspension tuning :slight_smile:

well thats quite a no for me especially your fuel economy :laughing:

172

it is rather frustating for me as i still could not even get a sub 2:24 car.
@puffster, and i thought having a 127kg/h fuel consumption with 97(is it kg or liters?) fuel tank is bad.

that aside, there quite a math that i can’t figure out here. like is it worth it making your car much more powerful with a lot more fuel consumed?
i mean, you may be 1-2 sec faster that the competition, and that stacks up over the lap, but since you’re stopping more often, you spend THAT much more time in the pits and the advantage is gone.

in short, just how thirsty can you make your car before it need to go to the pits too often to hold the advantage over time?

im also wondering what kind of camber angle are you guys on? since, you know, tire wear.

173

Has tyre wear been changed from the 1966 season or can we expect the tyres to last roughly as long as they have so far?

Because depending on how that goes, the limiting factor will actually be wear and not fuel.

174

talking about consumption… if I calculated correctly, my turbo car goes through a 78.8kg tank in 9.3 minutes… so I did not care about camber (2.4 rear I think) and tyre wear because it will be changing them non stop :smiley: It is fast tho…

There’s a 4.5 hour race to do :smiley:

My personal opinion is that more than 40 minutes between pitstops is too much, as you will be losing lots of time with worn tires the last 15 minutes like Leonardo9613 pointed out. With tyre wear like '66 I think the sweet spot is somewhere around 25-40 mins considering refuel times and tyre change times, hence fuel consumption is not as important. And refueling 45-60 liters is optimal to get the most efficient pits as well.

If I have a lap time of 2.20.5 and my competitor has a lap time of 2.23.5 there is a 48 second difference over 16 laps. Say I have to pit every 8 laps and my competitor has to pit every 16 laps. Then I have 48 seconds to perform that middle pit stop as we both have to pit at 16 laps, Including entering and leaving pit, that should be close to it so an exciting race in this case :smiley:

he’s striving to be the vikus Ver. B :stuck_out_tongue:

anyway. 40 mins huh, mine only need a refuel every 45 mins on the worst case of fuel consumption which i doubt it is, although im pretty sure it will be pretty high.

179

if my calculation is correct i’ll need around 13 stop to refuel in a race and barely hit the 2:21 which rougly about 27 mins, you guys seems have very aggressive approach about power

Tyre durability in general has been increased by 30 % if I remember correctly. But the effect of camber has been increased again, that was a little bit broken before. So in the end, with your usual camber settings, things should stay almost the same. But this also means you can save up your tyres a bit better with low camber settings. That should be better for balance now.
