CMP Time Trial report
Posted: Mon Apr 10, 2006 12:57 pm
I spent this weekend in Kershaw, SC running the Track Trials at Carolina Motorsports Park (CMP). A fun but lightly attended event. We had 36 people running the TT along with an additional 50 or so running the level 1 PDX. We used the full track with the TT running a session, followed by the 3 groups of the PDX. This allowed 4 on-track sessions per day.
Since this was my first TT event, I thought reviewing what I did would be helpful for others wanting to try it out. I was running my Miata so making sure it had the right safety equipment was the first item. My harness was 6 years old and TTs require it to be 5 years or less. That required purchasing a new set of belts with arm restraints since putting a window net in the Miata would be difficult. My roll bar was already legal so I was covered there. Only other item required was a fire extinguisher mounted in the car.
For personal gear the list was much more extensive. A protective racing suit is required. It can either be a multi-layer suit or a single layer with fireproof underwear. I opted for the single layer as I needed a two piece to fit properly. I was able to purchase a number of items off EBay and save a little money. I also needed a new helmet as my old one was M rated and TTs require a SA rated helmet. Due to my moustache I also needed a balaclava. My gear bag ended up with the following items: helmet, long underwear, socks, balaclava, gloves, and shoes. I was able to buy it all for less than $600.
I arrive at CMP (5 hour tow from Roanoke) and register but tech is closed. I unload the car and get it ready for tech inspection in the morning. I get up at 6:30 and people are already rolling in the gate. I load up my gear and head over to the tech shed. Since it was my first inspection and I need a log book, it took awhile. I had to have an identification number stamped on my rollbar that was entered into the log book. All the pertinent car information had to be entered as well. The inspection also included checking of my personal gear. I get handed a loaner transponder that is used for timing. Hooking it to the car with zip-ties is a challenge. Most Miatas with towbars mount them there since front-back position isn't important.
Next is the driver's meeting covering the procedures for the day. Main points were covering the flags and what to do for each one. Any off track excursion was a black flag and required coming into the pits for a check. Starter would have a green flag for timed runs and a checkered flag for the end of session.
We then suit up and get in the grid area. Cars were grouped by types and performance. Formula cars were one group, sports racer another, all the Miatas (7) in a group, the Hondas and other small sedans, and the V8 cars. Each session consisted of a warm-up lap followed by timed laps then a cool-down lap. First session is a practice session and doesn't count for scoring. Cars are sent out with about 15-20 seconds between them. Passing is allowed only on straights and when acknowledged. Car being passed always stays on-line and passing car goes off the racing line to make the pass. Since this is my first time at CMP, I get passed on almost every session.
Saturday started with the practice session of 2 timed laps. My best lap was 2:16. Our next session was 3 timed laps with my best at 2:12. Then it start raining at the start of the 3rd session. Track is wet but no standing water. I go out with my V710s and run a 2:21. A couple of cars slide off the track but no damage. We have the option of a 4th session but it's raining harder and would require rain tires. I opt to skip the session so I don't have to change tires in the rain. Most others do the same since Sunday's forecast is for clear and sunny.
I set a goal Sunday of getting under 2:10. In the first session I go out and get down to 2:11. Next session is about the same. Third session is extended to include 4 timed laps. I'm still running 2:11 but times are more consistent with less than 2 seconds between best and worst. It looks like we'll get our 4th session before 3:30 but one of the modified Camaros messes up in the kink on the back straight and rearranges the tire wall. Driver is ok but car needs a lot of fiberglass. Everything is held up for ½ hour while course is rebuilt. I decide to pack it up and get an early start home.
The other drivers were very helpful in pointing out faster lines through the different sections. When I get passed by another driver, I try to follow their line and learn something. Noticing their braking points is helpful since that's my weak area. I found that I'm braking too soon and not at the threshold.
The track is a bit spartan compared to VIR but has plenty of paddock space. All the paddock is grass and sand. There are plenty of electric outlets - as many or more than VIR. There are restrooms and showers for campers. Food service is limited. For those not staying at the track, motels are about 5 miles away.
