CTSCC Race #1 - Daytona

Performance Technic

If you read my last blog post regarding my first outing with BimmerWorld Racing and driving the new 328i at Daytona during the Roar Before the 24, it was pretty obvious that there was a lot of excitement in anticipation for our first race of the season.

I flew back to Daytona for the first IMSA Continental Tire SportsCar Challenge race, eager to get behind the wheel of the #81 car again. I had picked up so much speed from the beginning of the testing until we had packed up. As such, I was anxious to keep the momentum flowing through three practice sessions before qualifying.

Judging from the results at the Roar, I felt pretty strongly that Tyler Cooke, my co-driver and I had a good chance to qualify well and possibly even fight for some serious points in our first race together. I believed that I could still go faster and that there was also some speed left in the car as well. The only thing I wasn’t entirely sure of was how it would be to dive head first into the deep end of a pool packed with talented, hungry pro racers. Well, I was about to find out, or was I?

 Our practice sessions were full of frustration and concern with nothing but trouble with every outing. The team worked so diligently to repair the car and target the issues so that Tyler and I could at least set a few laps. However, by the time that qualifying had come about, I had only completed one full flying lap. 

The culprit was a bit of a surprising one. The team identified that there was a problem with the fuel rail, as it had broke, spraying fuel everywhere. Once they team had replaced the perceived faulty fuel rail, the vibration and added stress appeared to then trigger a coil failure. Once the coil was repaired, it was now time to qualify. I was sent back out for qualifying, only to encounter another broken fuel rail. 

After further inspection, the team discovered that a missing seal on one of the injectors was the culprit, which caused the misalignment and unnecessary tension on the fuel rail. The added stress and vibration caused it to fail.

It was pretty disheartening to not qualify for my first race, especially when our sister car, the #84, qualified right outside pole position. It would have been great to have qualified at the front of the grid with our teammates, however Tyler and I were determined to fight our way up from the back of the pack. If anything, it would make for an interesting story!

On the morning of race day, the #81 BimmerWorld 328i was ready to take to the track for the fourth and final practice session before the race.  Tyler took the car out first and then I jumped in after a quick 10-minute stint by Tyler. On my first lap out, the car overheated, so I dove back into the pit. This time the team discovered that the engine had suffered a blown head gasket.  

With only minimal time before the start of the race, the clock had worked against us. We couldn’t swap a new engine in time and we couldn’t jeopardize the season by entering the car into the race, given its current condition. Thus, we were forced to withdraw from the race.

Obviously, it’s a big disappointment for my team and my sponsors Supertech Performance, Performance Technic, QuickJack and Speed SF. It’s especially tough knowing that we walk away from the first race without any points. Results like these can haunt an otherwise stellar season later on, and may put significant dent to my aspiration of winning the championship. In the end though, this is racing after all. These things happen. We will have an uphill battle from now on and we cannot afford any setbacks. 

My feeling with the team is positive and I am confident that we can bounce back. Sebring is one of the toughest tracks to learn, however, with more than a month break, you can count on the fact that I will use that time to train myself thoroughly.

 The next time around, I’m sure that I’ll be writing a much more entertaining and exciting article!

Blackhawk Cars & Coffee

Performance Technic

The monthly Cars and Coffee held at the Blackhawk Automotive Museum is one of my favorite meets to attend. There is always a huge variety of cars displayed, and it’s most often a perfect mix between old school and modern. The event hosts are friendly, as are the people who show their cars. It’s a great place to go to learn about the unique vehicles in the area. I found myself stopping to talk to someone just about every 15 minutes—a fair number of those people were actually customers here at PTech. One thing that every conversation had in common was how absolutely freezing it was outside. However, regardless of the weather, it was a fun time. There were some very unique vehicles that showed up this month, like the Volkswagen Microbus, a turbo, M30 swapped E9, and an early model Pinzgauer Utility Vehicle. 

What I really love about Cars and Coffee is that regardless of the vehicles that show up, there’s usually a genuine atmosphere. People are quick to talk to each other about their cars, even if they’re from completely different styles (or even generations) of modification. I like to see boundaries like that broken, because when it comes down to it, we really are gathered for one thing: the passion for everything automotive.

S85 Rod Bearings

Performance Technic

An article written by Randy Yuan.

Recently there have been many threads sprouting up on M5board regarding the E60/61 M5 and E63/64 M6 cars having worn/spun rod bearings. Some bearings show minimal signs of wear of just the lead layer being exposed, but majority show heavy wear in that the deepest layer of copper is visible. Definitely if you are down to the copper layer it is time to change out the bearings. Many of these instances actually result in the owners replacing the entire S85 engine block due to metal shavings found in the oil or in worst case engines just completely failing to operate.  It seems that having an F1 inspired engine comes with F1 tolerances. BMW had released a newer rod bearing supposedly with larger tolerances to help address these issues.

Taking oil samples and sending them to Blackstone Labs for an oil analysis is one way to check on the health of your engine. For me, my past two Blackstone reports came back clean, but my car's mileage was getting to be high at 83,000 miles so I decided to take preventative measures and approached Performance Technic to have my rod bearings changed out for WPC treated ones, which are not only stronger and more durable than OEM bearings, but also have reduced friction due to the treatment.  Details on the treatment can be found here (http://www.wpctreatment.com/). 

Even though the newer OEM rod bearings supposedly had larger tolerances, I wanted to play it extra safe by adding the WPC treatment. 

In addition,I also asked PTech to use ARP bolts as they only require one torque instead of three in order to properly stretch the bolts. I also decided to install a new VANOS high pressure line and engine mounts. Leaking VANOS high pressure lines is another common failure for the S85 cars due to the line not having a proper bend to attach to the VANOS pump. A lot of the folks on M5board suggested swapping this line out with rod bearings while the car is apart so I decided to do the same. The engine mounts I also threw into the job since they would be easily accessible and my current ones already had over 80k miles of use. I basically vouched for a whole refresh of that engine bay area for preventative measures.

 Some fellow M5 owners question me as to why I would change out my bearings when my Blackstone reports looked great. Three words: Peace Of Mind. Every few weeks I see a new thread appear on M5board regarding a rod bearing failure. Peace of mind trumps all in my book and the cost of a rod bearing job is much cheaper than having to buy a new engine God forbid the worst happens. It's important to me to do whatever I can to keep my engine running strong and healthy and preventative maintenance is the path I use for accomplishing that.
