HQ Autosport is currently building 2 new Spec E46 cars. We will keep one and sell the other. This class is just getting off the ground with the first HQ Autosport Spec E46 nearing its first race it is currently the first car on the West coast built for this class. The goal was to build a car to compete in NASA's Endurance series in the West and we think this car as classed within NASA's current rules will be competitive.
SE46 looks like a great next step for SE30 folks looking for another spec series with competitive racing but with a more adjustable suspension. More photos here.
NOTE -- Spec E46 is not recognized this season but will most likely be recognized for the 2015 racing season.
When we did the "Version 2.0" upgrades we cut the spare tire well out of the trunk in an effort to shed a little weight and make space for a rear diffuser. We did some research and determined the angle based on the cars stance. The rear valance was trapping air so even if we don't achieve added downforce we hope to gain something from minimizing drag from the trapped air. Go here to see some photos of the diffuser build.
Chuckwalla Valley Raceway BMWCCA Club Race 3/19 & 3/20/2011
The first BMWCCA club race at CVR hosted by the San Diego chapter (which did a great job all weekend). This was a challenging weekend to say the least. We arrived early on Friday in order to get some testing in. After running 2 sessions we realized that the engine was running hot which could only mean.... head gasket. We started the job at 3:00 pm and completed the job at 8:00 pm ready to hit the track on Saturday and the scheduled feature race. Go here to see our "splitter cam" video from the first Friday test session.
Saturday's schedule was a practice session (around 9:00 am), qualify (after lunch) and the feature race starting around 4:30 pm. During the first lap of practice the exhaust note changed from it's normal sound to a small exhaust leak. The car was still making power so we continued. A half lap later the exhaust note increased and we could feel a slight power loss. A couple of turns later we lost boost and the car was very noisy.
We pulled into the pits and our wastegate had come loose and was hanging by the vacuum hose. We lost 3 parts on the track (2 V-band clamps and the valve seat). Long story short our day changed from race prep to make the race at any cost. Our only option was to find the parts. We went to the video and figured out where the part fell off the car. We looked at every corner worker break (there weren't many) and every spare minute that the track was cold. About 2 hours before the race we found the one key V-clamp we needed for the car to run. It was slightly down on power but our goal of making the race was in reach.
We started 31st out of 31 cars on the grid due to missing qualification but in within 15 laps we moved up 12 places to finish 18th. We were happy with the result based on the challenges the day threw at us. Go here to see the race video.
On Sunday during the qualification session we blew another Getrag 240. Now we know for sure that the Getrag 240 can not handle the torque we make. Look for a transmission upgrade coming soon.
We made lemonade and even though we weren't able to race we scored a ride in the pace car for the start of the Sunday points race. We got some cool shots which could show up in Roundel. Go here to see some of the Sunday race photos.
Chuckwalla Valley Raceway 1/15/2011
With the car tuned and our fuel injector issue resolved the next step was an on track test session. CVR is a great new track and its always fun to run there. We ended our second session of the day with a bang. Go here to see the video.
We participated in a joint POC/BMWCCA track day weekend at Chuckwalla Valley Raceway just outside of Palm Springs. The track is new which means it's freshly paved and smooth. It's also fairly wide in areas and should make a good venue for the upcoming San Diego BMWCCA sponsored club race in March 2011.
Anyone located in Southern California needs to get out there to either watch a club race or participate in a track day. They are still building up the facility with many of the permanent structures scheduled to be built in the summer of 2011 when the track activity slows down due to the summer heat.
Getting back to our testing weekend at Chuckwalla, we thought the car would run well based on the previous tuning session in September. It still felt like it had a slight miss but the dyno results told us the car was running so we were optimistic going into this test weekend.
We put the car on the track for the first session and it ran about 75% of what it's capable of. We were experiencing a power loss that felt like either fuel or ignition. What we didn't know was that first session would be the best the car would run all weekend.
We began our troubleshooting process and systematically narrowed down the issue suspecting it to be fuel related.
