This is a somewhat belated update on the Chin Motorsports event on Road Atlanta's challenging and fast road course. Four Vipers were there. Three were gen V's (two of which were orange TAs) and a terrific looking ACR that was yellow with black stripes. The ACR was in the novice group with the remainder in the advanced group. A good friend of mine was his instructor all weekend and commented about how well the driver was progressing. I suspect he will be moving up to the next level soon if he hasn't already.
Saturday has hot. The air temp in the afternoon was about 96 degrees and the track temp got into the 130s. Sunday had some cloud cover so the temperatures were a bit less. Rain was expected, but other than a few drops it didn't happen. The hot temperatures really effected engine power output and, of course, made the track a little slippery in the afternoon.
My TA ran well all weekend as did all of the others as far as I could tell. The Gen V non TA did get a code for a intake map sensor (If I recall correctly). We cleared the code and it did not come back as far as I know. I followed the other TA in one session and he was pretty well able to walk away from me. I am still using the stock tires and brake pads. He had Hoosiers, aftermarket pads and some chassis mods. He was very quick. Guess its time for me to put on the Hoosiers and Carbotech pads. While the stock tires and pads are pretty good, I am convinced that these upgrades will make a huge difference. Now if I can just upgrade the driving skills!
Road Atlanta is an awesome track but one that commands a lot of respect. The speeds are high and some of the walls pretty close. On Saturday I came up on a BMW sedan in turn 3. He went in way too hot, stabbed the brakes which shifted the weight to the front tires. The rear end came around on him and he hit the Armco barrier pretty hard. The driver was fine but the Bimmer will need new sheetmetal including front fender, door and quarterpanel. No doubt a very hard and expensive lesson.
This was my sixth HPDE weekend in the TA. I have had it at Sebring, Barber and Road Atlanta. Since this is my first Viper, I have used the stock tires and pads at all of the events. I did put Motul 600 brake fluid in and am using Mobil 1 15w50 in the engine. The car has headers, a Teamtech harness and a tow hook, I have always thought the way to learn to drive a car is to drive it on street radials. This has worked pretty well except I did blister the left front tire at Barber and had to replace it. The Hoosiers and Carbotechs will go on before our next event this month at Barber. The under hood temperatures on the Viper seem to be quite high. We removed the engine beauty covers and this seemed to help a bit. Before their removal I was getting some codes for random engine misfires. The dealer could find nothing wrong. Since the beauty covers came off I have not had anymore codes. Who knows!
I have done a lot of track day events with various organizations. I really like the Chin events as they are well organized and generally run on time. Safety is a big deal for them as well. I hope to see more Vipers at future events.
