I love racing Porsches. Ok there I said it, like nobody knew that. But I will elaborate, here’s why I love it:
It’s all about the feel inside the car, while driving. Alright, I admit it doesn’t hurt these cars look really good and fast on track, but going back to the core, it is about the feeling.
Driving a car like this, I have a pretty big engine mounted all the way in the back, in a comparaby small car. The engine is pushing the whole vehicle in front of itself. The front end gets pretty light, the behaviour with that weight in the rear can get a little fierce, but with the right touch it just gives a huge pleasure to keep it in check, to control a car like this.
Upon applying the brakes (Endless ME20 pads in my case), the car squats wonderfully in the rear, and more than any other car, it feels like throwing in an anchor and then reeling in, or actually, hanging on to that rope.
It is really notorious how slightly reduced grip in the rear tires, make that “rope” feel a lot slipperier, the feedback is absolutely instant. S-turns is not a chapter for the faint hearted, but with the right tricks, feel, setup and technique, the car will shoot through pretty fast… Over the limit it will be a handful to sort out, and not very fast.
The engine note (not the exhaust part) from the flat 6 is exceptionally notorious and it has a quality feel and sound to it that make me want to repeat it over and over again, for hours. Only sad part is that that Turbo is so powerful you really don’t get to stay in the sweetspot between 6000 and 7000 rpm too long. In a Boxster you’ll get to listen a long time, which sometimes is more enjoyable to be honest. A trained ear will easily detect the sound of a Porshe form any other car.
It’s a powerful beast, in a stylish suit. Purpose built, with performance to surprise and scare most people, and it has that special feeling - it is engineered and designed for the true driver to never want anything else. I got to tell you, once I started racing a Porsche back in 2001, it was where my passion found “home”, when it comes to motorsports and racing.
Auto Club Speedway, Sunday Nov 15; City Tire Online and Hankook Tire had hooked me up with tires so I could head out to do a competitive shake-down and to gather some data for next year’s Redline Time Attack season. - BTW how do you like the paint job of the GT2 aero? Done by PAC Autobody and Paint, Wilmington.
Already at the time of the drivers meeting, it was clear that it was a really good turn-out, very well done by the organizer to attract so many drivers. Mostly street class cars - that class was packed(!), but also a large amount of modified cars. Unlimited starting list looked a little sparse compared to the other fields.
The Modified AWD which my car is currently classified for, was a lot bigger and more competitive now than when I visited Redline at Buttonwillow at the beginnning of the year (that time I took 5th with far from full size tires). The class is now full of Mitsubishi Evo, Subarus and Nissan GTRs, with a varying degree of HP, weight reduction measures, aero etc. A true builder’s racing class.
On my end, I started out to bed-in the brakepads and feel out the setup as the tires got up to working temperature. The ME20 brake pad compund proved itself very strong for full on race pace, always good initial bite and friction and very easy to modulate.
Tirewise, the only DOT approved tire Hankook could find for the 12×18 GT2 wheels on short notice was Ventus R-S2. This is a very good performance tire indeed, however not a full R-compound in comparison to some other brands used in my class with down to half the threadwear rating, but this is what I had and I was decided to make the best from it!
I had prepared the car with a number of adjustments, to suit the track and the tires.
I had stiffened up the front swaybar setting to counteract the otherwise expected oversteer. I also removed the usual 1mm negative toe (toe out) since I would not need crisp turn in, this would come by itself due to tire balance. In the 4WD Turbo the car needs a lot of front grip on corner exit to not start pushing, this would also be better with no toe out. I lowered the rear ride-height a bit from an aggressive sprint setting and I was conservative on the camber angle in front since I currently don’t have adjustable camber in rear (this will come). Also rear wing got a few extra degrees. The results was… a very good starting point.
Lining up for pre-grid: Mod class has some very very serious racecar builds, as well as performance cars with various amounts of track preparation. It was obvious that I was down on power within my class. With appr 500hp you would think the car would be pretty fast - but some of these Mod AWD cars have absolutely astonishing HP numbers. Pretty crazy to see.
I kept working on the setup as the day went along, and at the end the car got really well balanced. Compared to a modern Porsche racecar on slicks, it is still pretty moderat - tires play a huge role as does the weight of the car, so there is a lot of potential for improvement.
With the R-S2 performance street tire I recorded steady state G-forces of 1,15G through turns (the banked turn 1,6G). This winter I will get some efficient upgrades done, to reach a higher grip level. Photo: Larry Chen
With the setup changes and the able support from Hankook to optimize tire pressure and temperature build-up, my laptimes went from consistent 1.51,7, via 1.50,0 (Time Attack 1), to 1.49,2 (afternoon practice).
I my 2nd Time Attack session I didn’t post a better time, two cars got into some type of incident and the session was restarted when I had hit 1.49,6 on my way to ideal tire temperatures for my third lap. I didn’t have enough gas though to do more than 5 laps (warm-up, 3 TA laps, cool down lap), so even though I gave it a shot I just had to roll into the pits when the engine started cutting out due to gas surge.
Not much to say about that, my final position in Modified Class AWD was 8th.
It was a sheer pleasure to put the car through its paces and working on the setup. Pushing hard drivingwise and gathering a lot of information on the data logger are the main things to have done going into the winter break. It gives a clear picture regarding exactly which upgrades to the car that will make the biggest improvements.
Thx City Tire for support and photos (all expect marked “Larry Chen”), thx Hankook for support and tires!

Carl’l perspective on Formula Drift Irwindale.
“”FD Round 7 - Irwindale: DNS despite huge team effort
Practice on Thursday started out well, better already in the first run than we ended practice last time out at Irwindale so quick fast learning curve as usual. The new exhaust is really good for the throttle response in the City Tire/Kallusive Clothing 350Z TT, which helps a lot especially up on the steep banking of Irwindale Speedway. I played around a little with lines, started to move higher up on the bank and in general felt very good about the precision of the car setup and the track layout. Traction as always hugely improved since we got the Carbonetic diff in the car and very smooth, saw a lot of jerkiness/shifty behaviour on the bank from other cars on the banking. Our City Tire/Kallusive Clothing Nissan 350Z TT was also looking good with Sam’s Autoland having taken care of painting some new AIT bodyparts for us.
To our great dismay our super strong engine started dropping oil pressure and making noise in the middle of my 5th or 6th run, I just had to abort and as I was rolling into the pits, there was some serious clonking going on, not good. We towed back to the team area and loaded up on the trailer to do some diagnostic work at the shop. At the end of Thu night, after discovering a pinched/seeping oil line and trying with the engine full of new oil we concluded this car won’t run without a new engine.
Fri morning the team gets started with the very able hands of Technosquare to swap the engine. Work progress went really well, by lunchtime the old engine was out and the new one about to be dropped in. By this time I had to head over to the drivers meeting and then just wait at the track for the team to show, worst case for 2nd round of qualifying but at least a shot to get into top 32.
It was a loong afternoon. As my fellow FD drifters were lining up to qualify, the team was reporting from the workshop - “wastegates on”, “exhaust on” etc and I was keeping them up to date with the progress of the qualifying which actually started a bit late. Ready with suit on and helmet in hand, I got to watch a lot of qualifying runs…
As 2nd cycle rolled around and the team was loading up over at Technosquare with the car now ready to rock again with a new engine, we all realized there’s no way they’ll make it through traffic on a Fri in LA in time to qualify. Anyway who knows, maybe someone releases a ton of oil on the track delaying the qualifying for clean-up - so the team kept moving anyway. However, 2nd cycle of qualifying went really fast and all of a sudden session is over - and our FD season is over. Not a great way to end it, sitting next to the track instead of in a car flying around the track, but absolutely nothing to do about it.
The team rolled in just as the autograph session started right after qualifying. After signing a huge amount of programs, helmets, t-shirts, bags etc - the line of fans was huge! - I head over with the team to setup our pit area, for the fans to see our car, and we stayed to watch and support our friend drivers at the track both Friday and Saturday.
Props for Matt Powers and Michael Essa for really doing well this event, I was sad to see fellow Z-drifter and Hankook driver Robbie get knocked out after some solid runs taking out already crowned 2009 FD Champion Chris Forsberg (congrats!).
Now, silly season is already at full speed. Even though most people take a week off from thinking too much about drifting after a busy season, it’s the big topic now who’s driving what car on what tires for what team next year. The FD Awards Banquet is tonight, it will not only be about trophies and awards but for sure also a huge gossip event…
From my side, there’s one or two more race events coming up this year before this motorsports season is fully ended, more news on that soon.
Thanks to FD for a well run professional show and thanks to all fans for showing up and just being great and enthustiastic at the races - it rubs off on everyone!
Thanks to everyone who supported our first year in FD and made our car really competitive already by mid-season, Hankook, Kallusive, Carbonetic, AIT Racing, APR, Technosquare, South Gate Collision, Sam’s Autoland, Endless, Zeal, Everitt Boles Motorsports Insurance, all the people involved - Chaz Kallusive - Justin (building on the car) - Carey (gearbox swap Atlanta) - Howard (engine swap).
Additionally from my side a huge huge thanks to City Tire Online!
See you on a track soon. Keep your eyes on this blog to know when and where.

Ok boys and girls, after having done two Formula D events, we took a great step forward in my 3rd ever Formula D event which was Las Vegas, by qualifying 7th(!). I think we can be pretty proud over how fast this small team, with great support from friends and sponsors, has gotten a whole lot of things right with the car.
It was a truly eventful weekend again, just like at Long Beach when everything was new but made top 32 first time in FD, and at Atlanta when the gearbox was completely gone by qualifying (I was lucky to pull it off anyway with some creative driving to make top 32). That time we swapped the gearbox until 5 in the morning and made some good tandem runs against Darren MacNamara who went on to podium.
By the time Las Vegas came around, we had developed and setup the car to a level where it was finally like it should be to drive. We had an amazing team effort just before qualifying, as the rear camber and toe arms snapped when I was scrubbing off the tires for my first qualifying run. Just like that. Wow. Glad that didn’t happen during a run on the course.
To fix it before qualifying run 2, evveryone went in different directions to get stuff or get hold of people. Not easy with almost everyone out on the grid! Forsberg offered up one arm, we got a welding machine from Rene’s Motorsports, but where is any sufficient power to run it??? Dynamics came to the rescue on that one. Now, who can weld aluminum..! Rene himself showed up, clock ticking fast now. Most cars had done qualifying run number 1… With express speed our super tech Oskar got the arms on, I barely had time to get the helmet and seatbelts sorted out. In my head - one shot only, zone out everything else.
Like mentioned, with the APR and AIT parts and a well needed diet on the car, I was finally able to make full use of the grippy and smoky Hankook RS3-tires we run on, and drive like I wanted to in Vegas, not just trying to overcome difficult car behavior. This was also a new track layout - for everyone! This gave equal chances to all newcomers in FD when the teams and drivers who have been in FD many seasons before had no setups to get a head start with, or any previous track experience here.
Didn’t take long for the qualifying score summary to come up and there we go, 87.5p! This was a big reward for all the work so far, finally. Now we know. For SURE.
Here’s a video of the second half of the qualifying (if someone has a full video from qualifying including the 86mph entry let me know and I will post it up).
Carl Rydquist Las Vegas Round 4 Formula D qualifying run from City Tire Online on Vimeo.
Later; ran some practice, followed a slow car who lost the drift, later lined up with Dai. Left some space, but grip had rapidly disappeared and still being close to the edge, I tapped the tire wall. The team got some work on their hands but car was fine for warm-up.
Next day - warmup. Now it was pretty well known it was getting slippery out there, many cars had brushed or hit the wall. This fact and rememering the close call last night I took it easy, lower revs and initated really early… but believe me I was seriously surprised over literally no grip at all, not just low grip, really really no grip. Couldn’t get speed to scrub off enough. A mix of factors left me needing an additional 2 car lengths, this would have been enough to avoid hitting the wall…
Very sad moment, no chance to get the car fixed fast enough to make the competition rounds, to be able to follow up on a very good qualifying and car setup, so that was our end of that FD event.
Moving forward, we brought home some pretty cool statistics after only my 3rd ever FD competition, a pretty nice reward for the work done to make the car competitive;
Qualify in top 8 - Check.
Qualify ahead of reigning World Champion - Check.
Qualify ahead of reigning Formula D Champion - Check.
Qualify ahead of a 2-time Formula D Champion - Check.
Qualify ahead of 2009 points leader - Check.
Qualifying speed full points - Check.
These facts bring some pretty solid determination to our upcoming efforts and expectations. You can easily say we have raised the bar and from here on drift life with the City Tire / Kallusive Clothing Formula Drift Team will get even more exciting.
Next stop and season finale is: Irwindale Speedway! To this round we will come armed with a new open lightweight straight single pipe exhaust (another 50lbs lost on the car), raw engine sound and more torque. Don’t miss it!!!!
