BRC 1955 - The Golden Age [Qualifying R5]

[TheBobWiley]

That sounds awesome ColbatGirl, looking forward to battling it out with you in the coupe body!

[07CobaltGirl]

I doubt it'll be doing battle with you. You might actually see it in your rear view though! #babysteps

I made a car as a test since everyone is saying that OHV is significantly worse then the other valve systems. (Also, I was board).

I got it to match the performance of the car that I had in this past test. Maybe .4 of a second slower or something. That means it would have broken 1:40 in Der Bayers system so it would have gotten around 1:39.60 or so in the test (rough estimate based off of how much faster my car was in the test compared to vanilla Automation times).

It is still more then a second slower then the revision I have sent in but that's mostly because I dont want to test several dozen different suspension set ups right now. But with more time and fiddling I think I could get it to match the revision as well.

I want to post it in here for people to look at but that's not going to be until after submissions are closed. I dont want someone badge engineering it and claiming it as their own.

[TheBobWiley]

Holy crap, you guys are getting competitive engines from OHV.... When I look at them their power bands and weight are basically useless..... Guess I just don't know how to design/tune those old engines :\

[strop]

I can relate bob. Every OHV tourney I enter, I tend to do pretty poorly! It makes sense, since my preference is for the antithesis: high revving DOHC engines

Hi guys!

So, reviewing my cars performance after the first pre-season test I found some stats that might need attention and I was wondering if anyone would give me some feedback.

Top speed: 195km/h, my car must have one of the slowest top speeds on this track. This won't be favorable on the Green Hell, but does it need a rework?
GripF: Only had 79% left at the end. Maybe not among the worst, but is it essential to increase it?
Fuel: I had 9.2 left... how much would be good to have left?

Feedback would greatly appreciated.

I can only assume you're running the coupe body with these stats, either that or a VERY inefficient, low powered roadster. If you're in a coupe body those stats seem about right for a mid-to-high level tune. If you look at my stats I got to about 208-209 km/h, had .78 grip on the front and rear, and 9.4 fuel left. Your top speed is definitely a limiting factor and you may want to look into spending some money in the aero tab, reducing the amount of cooling, and messing around with your gearing and power band. Additionally, if you have high engine reliability you might want to try increasing your RPM limit and see if that helps out your top speed, if the limit is set too low for your power band it can reduce your top end power a decent amount. I was able to pick up another km/h but increasing my RPM limit by 1000, only dropped .5 reliability and made up for it through some engine tweaking.

If however you are using the roadster body, I would suggest looking at your HP and weight and thinking about adding more weight so that you can use a higher HP engine. More HP means more top speed and sometimes better acceleration. You may lose a little in cornering speed but I generally find that a .2 km/h drop in cornering speed is overcome by a better top speed for most tracks, especially if you get .10 or better acceleration times (look at your 80-120 km/h time).

Tuning is fickle and sometimes you can find a surprising amount of lap time hidden in the settings, sometimes you're lucky to drop .2 seconds. :\

Thank you. This is some great feedback. I'm using the small 40s body and mainly focusing on low weight. I'm streaching the revlimit quite alot past my actual power peak and I have the aero slider all the way to +10 already, everything past that scores negative on the price/gain scale. I think it's time to start adding weight and horsepower.

[Absurdist]

Aero slider on ten will cost a LOT. Two areas I suggest that may be better to sink money into are the brakes and even more so, the transmission. Low weight explains why you were so fast in sector 1, which is still impressive as you must have a really sweet suspension set up to make the MR work so well. I couldn't do that (I tried).

Probably your car will be best suited to brands hatch or Norisring, download them and use one/both of them as your test track. Practicing on the faster tracks I think will be, well, less useful, as the more efficient roadster body will just demolish you on the faster bits no matter what you do. I can't wait to see how you built your car!

[Dobble]

Just sent in my first revised entry. Top speed has been improved, fuel economy down 8%, a bit less camber, reliability improved and a nice time cut on the Automation Track. Can't wait for the next pre-season test.

EDIT: Forgot to keep with tradition and humblebrag with some statistics.

"Der Bügler" has a Drivability of 34.3, Sportiness of 22.1, Economy of 7.34lt/100km, short corner @ 1.23 and long @ 1.14
If anyone is curious about something else, you are welcome to ask.

[Zabhawkin]

I was surprised that I had no errors with my drivability/sportiness... I thought that car would have been all over the track. Though each lap was slower than the lap previous to it even though it didn't eat the tires too bad.

[TheBobWiley]

I had crazy awesome suspension for 1945, but how in the ba-jesus are people getting 1.2+ g's on the small corner??? Even with my 600 kg roadster I only got to like 1.15g and I think my coupe is at 1.14g...... Looks like the coupe may lose out to the '45 body

[strop]

What I find a bit misleading is that there's a fine tipping point between having, say, 1.24 and 1.08 in small and large circle test respectively, and 1.19 and 1.14 or something. But the highest circle test values don't always yield the fastest times even when everything else remains the same...

[Der Bayer]

Quick update: Thanks to conan and trackpaduser I identified and fixed a bug where the front and rear brake pad slider have been mixed up. They are named the same in the save file but not always saved in the same order. This won't happen again!

Consequences: I'll start making a new pre-season test video now and upload it in the evening already. Another one (the last one) will be coming on Wednesday. Submission deadline is postponed to Sunday, 7th of June.

[strop]

:O good catch, that would make a fair difference. I expect many of us are running 100 sportiness pad on the front and 0 on the rear. Not many other ways to get that front brake power up after all

[JasonPoland]

I would like to retire my entry for the competition.

[Der Bayer]

You can easily check if you were affected by the bug: take a look at you trim file and search for ["MinDiameter"]. In the lines below there are the two values ["Front"] and ["Rear"]. If rear is above front you are probably faster now than in the last video.

Info for all: mattmr2, RubenSL, strop and Absurdist are not affected. TheBobWiley for example was.
