Personal Hotlap - 2:02.706 - Bahrain International Circuit, Bahrain Grand Prix

Posted on January 11, 2008 17:05 by ScottDrake

This hotlap is from my third or fourth session at Bahrain. Still working out the line. Can't say I'm a huge fan of this track as the super-slow corners like 1, 8, and 10 leading onto a straight get kind of tedious. I like the 5-6-7 corridor and the braking zone through 9, but everything else in the first 10 turns could be better.

There are some corners at this track where you really need to practice looking as far ahead as possible. Coming out of turn 11, if I'm not looking way up into turn 12, I forget I have to keep turning. Same for turn 15. If I'm not looking way up the straight at least to the end of the curbing, I usually end up on the curbing because the corner goes around a bit farther than you might think.

Prioritizing the Corners of Bahrain International Circuit, Bahrain Grand Prix

Posted on January 9, 2008 10:47 by ScottDrake

As I noted in the "First Impressions" post for Bahrain, this track can almost be broken into two sectors. The first is more technical and includes corners 1-10, the second is higher-speed and includes corners 11-15.

I'm going to focus my attention first on the corridor that includes corners 5, 6, and 7. It looks like the most technical at the highest speed.

I'll then move on to the corridor that includes corners 11, 12, 13, and 14 which looks to be the highest speed but is not quite as technical as 5-6-7.

I'll come back and work through the long braking zone of 9-10 before moving on to 15, 1-2, and 4.

Data from the AI car including seconds between midpoints of corners:

First Impressions of Bahrain International Circuit, Bahrain Grand Prix

Before I get into my analysis of this track, getting it downloaded and patched was a bit of work. I ended up using this download:

http://www.f1gaming.de/downloads/rfactor/strecken/CTDP_Bahrain_F1-2005_Track_for_rFactor.rar

Patch 1:
Out of the box, the track surface is very bad in places and causes violent shakes in certain corners. This patch will fix that for the most part.

http://trd3.net/index.php?option=com_content&task=view&id=47&Itemid=2

The site is in Spanish. An English translation is available through this link:

http://translate.google.com/translate?hl=en&sl=es&u=http://trd3.net/index.php%3Foption%3Dcom_content%26task%3Dview%26id%3D47%26Itemid%3D2&sa=X&oi=translate&resnum=1&ct=result&prev=/search%3Fq%3Dhttp://trd3.net/index.php%253Foption%253Dcom_content%2526task%253Dview%2526id%253D47%2526Itemid%253D2%26hl%3Den%26rls%3DGGLJ,GGLJ:2006-41,GGLJ:en

This patch is installed by extracting the rar file and running the included executable.

Patch 2:
I also upgraded the cameras because the default spectator view didn't show much of the track because it was too tight on the car. The link for the upgraded cameras is available on the rFactorCentral.com page http://www.rfactorcentral.com/detail.cfm?ID=Bahrain%20International. It is the Bahrain Alternative Cameras by GTEvo link.

To install this, I extracted the rar file, and copied the file 1Shakir.cam to the C:\Program Files\rFactor\GameData\Locations\Bahrain\Shakir folder. Your install folder might be different. I then renamed the existing Shakir.cam file to Shakir_orig.com, and then renamed 1Shakir.com to Shakir.cam.

Fire up rFactor and you should see the track in the "CTDP F1 Tracks" folder.

On to the post ...

You really get the impression that this is a circuit plopped down in the middle of the desert. Like Sepang, it is a purpose-built track with lots of run-off area. It has some mild elevation changes that are placed in areas that making driving a challenge. The turn-in for corner 7 is very difficult to see due to elevation changes as is the braking point and entry for corner 9. Corner 13 is a high-speed uphill leading quickly into the braking zone for 14. The uphill is blind and landing on the wrong side of the track can really mess you up for entry into 14.

On first impression, you can almost break this track into two primary sectors. The first would include corners 1 through 10, the second corners 11 through 15.

The 1-10 sector looks more technical. It has three very tight right-handers, one of which funnels into a left-hander, a high-speed bus-stop-style section, and the long braking zone going into corner 10.

The 11-15 sector may be as technical due to elevation changes, but it is much faster with longer sweeping corners.

For timing, the sectors for this track are:

Sector 1: Corners 1, 2, 3, 4, ends at entry to corner 5
Sector 2: Corners 5, 6, 7, 8, 9, 10, 11, 12, 13, ends at Vodafone sign between 13 and 14
Sector 3: Corners 14, 15

Attached is a hotlap from the AI, as well as a screen shot of most corners.

AI Hotlap, In Car

AI Hotlap, Overview
Note: I had to use the tracking camera on this because the spectator camera that ships with the track does not show much of the track. I have since downloaded the updated spectator camera.

This lap was completed in 2:02.323 (122.323 seconds).

The gear, RPM, MPH, and time between corners are measured at the point the RPMs begin to increase when exiting a corner. The screen shots are also from the point of acceleration from the corner.

Let's take a look at a lap.

Corner 5 is a quick left-hander that muddles the braking zone for corner 6. Corner 6 is a quick right-hander leading directly to corner 7 which is a quick left-hander. Almost looks like a high-speed bus stop.

Corner 11 is a moderate-speed left hander leading into a long corridor with corners 12 and 13. Corner 12 looks to be an acceleration zone while corner 13 may be more measured but acceleration appears to continue before landing at the top of a hill and into the braking zone for corner 14.
