Personal Hotlap - 2:05.611 - Sepang International Circuit, Malaysian Grand Prix

Posted on January 4, 2008 16:50 by ScottDrake

This hotlap is from my third session at Sepang. Getting better with the line and with braking at an appropriate time. Still working out the line. I've got some work to do on the back corridor including corners 5-8. Those are extremely important for fast lap times because they are high speed.

The other thing I'm discovering is the curbing at this track is rough. You can put two wheels on it with no problem, but don't drop a wheel off the other side on most corners or it will wreck you.

Still like this track.

Personal Hotlap - 2:06.957 - Sepang International Circuit, Malaysian Grand Prix

Posted on January 3, 2008 12:48 by ScottDrake

This hotlap is from my second session at Sepang. I'm not dissatisfied with it, but it illustrates some classic mistakes that are hard habits to break. The primary mistake I'm making is focusing on entry speed instead of exit speed. In a lot of the corners, you will see me shoot past the racing line and the car I'm chasing start to pull away when exiting the corner. At this stage of my learning, I need to be focusing on the line and exit speed, not on how late I can brake.

But it's a start.

First Impressions of Sepang International Circuit, Malaysian Grand Prix

Posted on January 3, 2008 10:26 by ScottDrake

I like this track. It's challenging in different ways than Albert Park. Being a purpose-built track, it's wider and generally has a lot more of a runoff area. It has a decent amount of vertical change which adds more challenge to finding the right balance of the car while driving. It has a lot of corners that are long, sweeping, and fast which you will find more challenging.

I don't like how the AI enters and exits the pit lane. On entry, it is in the racing line and then veers wildly to the pit lane crossing the outer lane of traffic. Not sure how it will react if another car is out there. On entry to the track, it again veers wildly back into the racing line. I have yet to be hit by one, but I have seen other AI cars get hit by one re-entering the track.

I drove about 60 laps today and rode along with the AI for another 20 or so. I've gotten up to speed pretty quickly on this track after my initial analysis. I'm still finding it hard to put together complete laps, but I feel like I'm further along after this many laps than I was with Albert Park.

Attached is a hotlap from the AI, as well as a screen shot of each corner.

Personal Hotlap 1:54:926 - Albert Park Grand Prix Circuit, Australian Grand Prix

Posted on December 2, 2007 23:05 by ScottDrake

This is probably my final hotlap for a while at Melbourne as I'm ready to move onto the next track. My goal all along was to break 1:55 and I did it with this 1:54:926. There's probably another second or two on the track if I can put all the corners together. Sometime in the future, I'll revisit this track.

Future tracks will likely have more personal hotlaps posted. I was working on this track for a couple of weeks before I decided to start this blog. It's taken me a couple of weeks to get the site to this point. In the future, I'll be posting more about the tracks as I learn them, not after my analysis is complete.
