Went for a race around the ring before calling it a night, and dang was it an eventful one.

Started in 6th

That looks a lot like most of my starts on there today. But I did get a cleanish start on my last race, only got barged wide by the same jerk who punted me previous race. Had good luck as I only lost that 1 position that time. After having had a couple of run ins with him like that I was determined to punt him this time! And yeah, he doesn't make any major mistakes and I finish 6 seconds behind because I couldnt catch him. Got my SR back up, working on keeping steady DR, looking at hopes of "git'n gud!" At least as much as I ever can.
 
Ending the night with a classic:

5 sec penalty for "forcing another car off the road". It wasn't his fault either. He got punted by the Mexican behind him who casually drives by and finishes penalty free. From 8th to 13th with the penalty. -250 DR, neutral SR. Still at 93.

Great job. :cheers:

I didn't even make it to Willow this morning. :irked: Instead, I wasted my whole morning on race A qualifying, to only shave a tiny, tiny sliver off of my time.

This about sums it up. :lol:

This is me on Race C. After two hours I was faster, just 0.035 seconds, but faster!
 
Granadier
Not sure how it's modeled in GT, but in a real life engine braking will use limited to no fuel. The braking force is achieved through the dead compression resistance of the cylinder chambers without any ignition of fuel.

real life engine ? Race or Road car ? Race car always have fuel in cylinders irl
 
Don't know why I was stupid enough to try races tonight. Absolute chaos on the N24. Massive punts turn 1 both races, same player both times. Then caught behind roadblocks for ages that fight to the death against a pass. One prick waited until I am 90% past in the sweeping section in the forest then taps me and bounces off the wall. Wonderful 3 seconds. They finish ahead. People are just being psychotically aggressive for some reason. I still have only ever been through the starting turns without a punt once, and that was a barge pass that time. Am I the only one stupid enough to have this problem somehow?

Had worked my SR back up to 99 for several races, 2 races with :dunce::mad: drivers and back down to 88
 
Granadier
All of this. There's a reason that in real life endurance multi-class racing the slower classes are told to hold a predictable line so the faster classes can drive around them instead of weaving around the track to try and get out of their way. It's the faster driver's responsibility to ensure a safe and clean pass of the slower car, not the other way around.

Also @Sven4057 you are nearing 600 wins. That's insane! edit: and over 9000 races! :bowdown:

Sorry but thats not me lol
 
Race A, I'm down to 1.03.987.

What brake balance is everybody using here? I'm on -5, I did experiment with 0 but didn't notice much difference. The fact that the brake is hardly used in this lap, makes me wonder if the brake balance is making much difference at all?

In all the laps I've done, I don't feel like I've nailed that final corner once.

I haven't even done Nürburgring yet but I'm already deeply traumatized by some of these videos. :eek:

1:19:107 in the Mustang. A new personal best qt. Pleased.
Click to expand...
Well done, but keep at it. Even with my meagre skills there's at least another six tenths to take off that Mustang time (and I got the 86 down another tenth with optimal another three tenths below that).
Sven Jurgens
Looking at your feed, doesn't engine braking use fuel? I down shift late not to have the over revving engine suck fuel out of the tank, but no clue if that's a real thing.
Click to expand...

RacingGrandpa
On the road that is correct. On a race track no. Look at the exhaust pipe of an engine braking car in a race, it's shooting fire out of the pipe. Unburned fuel.
Click to expand...

Granadier
Correct, but it depends. I was describing road-legal behavior which was the wrong explanation given the context.
But the race cars won't be dumping fuel through the exhaust on lift at all times. Watching a GT car downshift into a corner you can see the flames with each shift because of the engine map blipping the throttle on the downshift, which ends up dumping some unburnt fuel into the exhaust which ignites there. Flames coming out on lift without a downshift can be a rich mixture from full-throttle suddenly having the throttle closed and the excess gets through unburnt. Feeding fuel into the cylinder at all times under engine braking intentionally though would just waste fuel economy.
Click to expand...

With a carburettor there'll always be fuel feeding when air is flowing. How much will depend on wether the venturi / jets are upstream (low flow) or downstream (high flow) of the throttle butterfly/slide.
With fuel injection, it's anybody's guess unless you have access to the actual fuel map. There are reasons where in some circumstances keeping fuel flowing may be an advantage, but in others (endurance racing being the obvious) you don't want fuel flowing if you don't need it for pushing the car.

Probably unrelated to fuel flow off throttle, but showing how much variation there is, I know a chap who rides an Aprilia motorcycle which is fuel injected. It has a fly-by-wire throttle, so the butterfly can be set by the engine management independant of actual throttle control position. It has three power profiles pre-programmed, street, sport and track. In street mode, slaming the throttle shut results in a nice easy slowing down. In sport, significant engine braking. In track mode it's locking the back wheel when you slam the throttle shut at high revs.

sturk0167
As I understand it, these guys are blowing flames out of their exhaust because the engine's pushing the air/fuel mixture out of the combustion chambers before it's been fully burnt. It's definitely different from what you guys are talking about, but it looks cool.

At full throttle, they will go through 77 gallons per minute.

This is a bench test of one of it's fuel pumps. This is only for 1 of the 8 cylinders. It starts off showing the fuel flow at idle, then full throttle. :eek: :lol:
Click to expand...

Those guys don't give a tinkers hoot about fuel economy and run super rich to keep the pistons and valves from melting. If they were running anywhere near an efficient fuel mixture, those flames would be blue rather than yellow (and the engines wouldn't last the first hundred metres).

Haha loving the debate about fuel use under engine braking. My hunch of using more fuel was more from a software standpoint:
Simple model, fuel use = fuel mixture time engine revs.
Thus higher revs is more fuel use. No clue if GTS models fuel cut off when you don't press the gas but of course it should otherwise coasting wouldn't save you any fuel. Yet keeping a bit on the gas under braking to stabilize the car will use fuel.

What I did notice in game that drafting at max engine revs can eat up fuel faster than powering along without drafting. That was my experience at Sarthe where with good drafting on the no chicane straight at max speed would consume my fuel faster. Higher revs more fuel use, regardless of the lower resistance from drafting.

Starting with the Supra this morning. I guess people aren't quite awake yet (neither am I) Got punted off in lap one by a Vette, went wide myself lap 2 and then barge passed by people trying to take advantage. Finished 2nd in the end since 2 and 3 ran out of fuel.

If the game is modelling fuel use even vaguely accurately, higher revs at same throttle setting = more fuel used, regardless of drag. Higher revs at lower throttle should use less fuel than at wide open throttle. If you were to sit on the grid in neutral with the throttle wide open and the engine bouncing off the limiter, it should use fuel at pretty much the same rate as pinging the rev limiter in top gear on a long straight.
Edit: this max throttle fuel comparison will hold true for a limiter that works by cutting spark. If the engine is fly by wire and the limiter works by modulating throttle butterfly or fuel flow, the comparison may break down.

Fun race. I gambled to get back in time from bringing my kids to the bus. I didn't make it. I come in, my wife is laughing trying to get the car to go in the right direction, doing donuts at the start. I quickly take over before the DQ timer sets in and start 36 sec behind 15th. Luckily no penalties. Checking the replay my car rolled gently into the pit lane at first, lucky auto-drive aim. She took over when it got out the pit. Instantly spun out. I manage to catch up, finish 7th. SR up, gained 1 DR point. Better than none!
 
After my first race of the week, I got enough DR to move up to DR B. So, I go back to double digits for car numbers. I feel primed to just DR farm all week. Even though I gave a victory away last night :banghead:, I am still finishing well enough to gain DR & SR. Crossed SR A again last night.
 
Hi to all ..
Yesterday in my Board profile (I-Runner_GTExD) I did only three race (I Came back late from swimming ..) and I tried the McLaren F1 .
I usually, when is possible, change car every race so yesterday was the turn of the Mclaren F1 as the first car of the evening/night .
I received that car from track experience gift and I used it only one time at Tokyo-wet in the off line part of the game, so yesterday as usual for me I entered the race with the countdown near the end, and I didn't chek anything except to set the TCS at zero ..

..During the race I noticed a little bit of oversteer and i had to brake at the Schumacher esses (the first time so far ... ). During the first lap i received some little "doorslamming":irked::mad:, did some overtake:mischievous: .. and NO pitstop:sly: .. but after two turns in the GP part of the N24 i realised :odd: that ...:nervous:

I was racing with RAIN TIRES .. :ouch::ouch::banghead:

I think I found the worst car already for race C. Renault RS 01. It's great on fuel, hardly requires any short shifting, yet halfway through lap 2 the back keeps braking out in all the 3rd gear corners. Both attempts spun in lap 2. Too slippery and no top speed at all. 7 useless gears. To the bottom of my list. It should fare better with a wheel, less tire wear, finer steering. But that top speed is so low, cars fly past from 1.5 sec back when entering the straight.

Next! Can't be bothered to set a clean lap 2 with this piece of junk 👎

4C is an excellent car
You need set fuel 2 in Nordschleife area
Set 1 in straights
Click to expand...

Agreed that it's excellent but I've never had to drop below FM1 in all areas. However I short shift around 75% of the time throughout both laps.

Some sectors I'll go at full rev or to try and push as far away possible from a clown/pack of cars so it's pretty flexible. It's noticeably slow on straights and that causes you to lose a bit of time, particularly between Kesselchen up to Steilstrecke. Each time I've finished with 0.2 - 0.1 fuel.
 
Last night had a good showing at Big Willow after two CATASTROPHIC races on Monday (dead last twice). I need to find a lot of speed in turn 1 & 2-3. I think the top of the hill blind right is the most difficult to nail. I'm coming out of it with some good speed, but from 2-3 takes a special line I haven't mastered yet. Using meta 86; such a lovely car to drive.

Tonight may be the premiere at the Green Hell for me. Tried a couple qualies in the Aston V12 and hated it. I refuse to turn on TCS for anything but Gr1 or Grx these days for better or worse. I know I could use it lightly while learning (or in this case, re-learning) a track, but I don't wanna! It's just not as fun anymore, and I don't get to practice throttle control and counter-steering, etc. It sounds like the Vantage may not be a great choice for the 'Ring anyway, so I'll use something else tonight. Maybe a good excuse to finally get in some American steel and try out the Corvette. I never drive domestics.

Well, apparently, starting last and gaining 5, 6 positions won't boost your DR too much. I had to qualify for race B.

Did one race, started P9, finished P5. I'm doing surprisingly well at Big Willow, very few mistakes, SR went to 99. Good week.
Click to expand...

Depends on the room. Race B, DR/B SR/B, started 15th in both races this morning. Finished around 5th and 6th in both, scored 1101 DR points.

The WRX is holding its own in the company of the Trophy's and TT's.

I really like using FM1 for the GP and FM2 for the rest (other than the straight, which I just read is called the Döttinger Höhe and is after a place where they used to publicly execute people) because it saves me the concentration of short-shifting. Plus, who doesn't like constantly redlining in a car that can't break? Good times. :D
 
The Citroen GT is pretty good at race C. It's currently in 3rd place for fastest second laps behind the Corvette and AMG. It's decent on fuel but allergic to grass, beware. Fast on the straights and very stable as long as you stay away from the edges.

The Supra didn't work for me from the back. It's very tight on fuel and the hectic starts (mid pack, DR too high to start last) burn up a lot of fuel which means a lot of saving on the Nord and/or starting with a deficit in lap 2.

So far, despite trying to start last, I've been punted / rammed off in about 60% of my races. The first 2 minutes is full scale war out there.

Scratch that, Ford GT just took 3rd place. However it was a clean race!!! And I was drafting a car in lap 2 without any incidents. Ford GT is pretty nice on this track, fastest lap yet lost DR for finishing 6th from 14th.
