    Yes at times this driver felt overwhelmed and definitely underfunded with pending divorce proceedings sucking up all available funds- so no room for wrecked cars. I knew the purple Miata was faster early and something was up this stint- I could get to him in the corners but he would pull me on the straights. As we approached the bridge I could see the Badger coming but I don't think the Purple car could. It appears that he is attempting to go off line trying to let me go by but I could be wrong. When I saw the Purple guy move over I let off knowing that things weren't going to end well. Gland nobody suffered any permanent damage and thanks for the show I have driven the dirty dodge plenty of times at Sebring and once at Daytona but this was my first Road Atlanta experience. It was a last minute decision to run with lots going on in the personal life. Just happened to be my 55 bday and said what the hell lawyers, kids and soon-to-be ex-wifes taking my money I am going to do something for myself. I watched about 2-3 hrs of video, how-tos, NSR in-car, other in-car, IMSA, blah, blah, blah... Everyone told me that videos and pics don't do the place any justice in regard to the elevation changes- being a Florida boy born and raised I had no idea what I was going to experience. Thank goodness for test day. First time over the bridge was like "where is the frickin road? I see nothing but tops of trees"!Never felt like I got a good corner. I actually ran faster in practice than I did in the race. My goal was to make laps and learn the track- didn't want to get over my head and break the car or mess up somebody else's- only went two wheels off in 5 once- stayed out of everyone's way while staying on-line so mission accomplished. I have been stalking this thread reading all the banter and in the end it is healthy for series- where racers will hold racers accountable for cheating, rough driving, etc. I think that it is really cool that we have teams and drivers from all walks of life and experience. We should be very thankful that we have a series like this that lets us flex our engineering skills (or lack there of) while being able to compete on some of the best tracks in the world. I had a blast listening to Ed's demolition racing stories and general knowledge off all things mechanical on the drive up and back- also really cool that he has been with ChamCar since it's inception. Thanks to the all of the hardworking folks who put this event together and congrats to the winners. What a blast of a track to drive, can't wait to get back next year- goals will be slightly more aggressive Tim

    The dirty neon had a pretty good start to 2019. 2018 had 3 broken clutches in 4 races and axles and overheating issues in the Dec Sebring race. We started off practice with replacing a brand new redline re-greased axle after few laps, I knew it was bad on the 1st RH turn, then suddenly the shifter became notchy and refused 1st gear. Replaced the axle and found the shifter cables missing their clips, about 15 min of work with a grinder, drill and safety wire fixed that! I also found out that Cool-It Thermo Tec brand acoustical/heat barrier tar mat isn't as good as mopar OEM (that had wore off) and burns/smokes from the heat on the firewall/tunnel area, its also a major pain to remove by the way. A late decision on practice day to disconnect the big rear sway bar, wasn't the best in hindsight as the car lost a ton of traction exiting slow corners, but it was fun doing 3rd gear burnouts on T7 and 10B exits. Most of the race was dealing with oil consumption issues in the catch can and an intermittent electrical short that acts like fuel starve on high G turns with certain drivers , but was remedied after a few min of troubleshooting. Overall we finished 24th and 2nd in class due to attrition mostly and received the sportsman trophy for having a driver from a crashed car in practice race, (and I'll add for helping repair Ed @Team Infiniti personal car after we made it back to FL and he decided to break it leaving my neighborhood with another 100+ miles to go, after a few hrs we made a solid repair with random stuff lying around my house). I haven't looked at much video yet, but figured I'd post up the in car from the dirty white neon (and a few laps earlier) between the PartsBadger miata and the purple miata. Not sure why my driver was following the purple miata being that far off pace, but maybe he was a little overwhelmed himself, first time at Road Atlanta and didn't realize that they switched drivers as it was much faster earlier in his stint. I probably would have attempted the same pass on those two cars.

    Went to the u pull to get a fender. It was a nice 15 degrees F. It was $10 fender day. Kind of crappy I had to chip it out of the ice. You southern folk have it easy.

    I wanted to examine this topic with some statistics, since emotionally this dead horse has taken a beating. Fuel comes up every year in petitions, but it seems like the ideas lack details on execution, proof or consistency. I am only looking at proof of a correlation, not trying to fix anything yet. This could be a good guideline for new teams, on what cars are pretty helpless and better left to another series, if nothing else. The idea is to try and keep this to "does it take x amount of fuel to be competitive" or "is having below x amount of fuel a handicap", from a statically backed standpoint. This is gonna be a little tough, cause several cars use all of the grey to dark grey area's of the rules (maybe an integra in the for sale section ), and the math will be based on the assumption the capacity is somehow linked to the oem capacity. Weight was grabbed from Edmunds or automobile catalog using the lowest weight the best engine package had (what you would race). The typical "champcar % weight reduction" factor was then multiplied (use 90%). Smaller non luxury cars get screwed in this, but we have to pick some number since I don't have a good list of race weights. Fuel to weight, FWR, is this 90% curb weight divided by oem tank capacity. I was able to get ahold of the race results for 2017 to current. I took the podium results, and just excluded cars that were EC. If an EC car finished 2nd, then I only used the 1st and 3rd place cars. The data was already immense, and with 88 races missing one or two isn't gonna destroy the trends. I made sure the highest podium was moved up to winner, to make sure the winner stats were at least accurate. Moving on, There are 110 teams who scored a podium since 17'. These teams used 32 different chassis makes, which shows some diversity despite 3 cars (NA miata + E30 + E36) being 59 of the 110 wins. Plotting a histogram of the FWR for these types of cars looks like what you would expect, a clump around the e30\e36 range Looking at all the races, you see a big clump in the mid 160s or better. Looking at all the races can be a bit deceiving, since we have some west coast races with very low turnout. Not sure how much fuel economy matters if there are less than a dozen cars still running at the end (at any pace). If we limit the conversation to races with at least 40 cars, we still have 47 races of data, potentially 141 podium spots, all with more people and hopefully good cars fighting for it. These results look more bleak for cars with poor fuel to weight. In the past 2 years with races that have over 40 people only 3 cars with a FWR over 170 have won a race. 3 out of 47. Of the races with over 40 cars, only 9 teams with worst than 170 lbs\gal have scored a podium. They scored 18 podiums of the roughly 140 possible chances. The 9 teams used 6 types of cars, Integra Gen 2 (10X), Civic Gen 5 (2X) and 6 (1X), Neon (2X), Gen 4 Mustang (2X) and SC2 Saturn (1X). Besides the mustang, these cars are in the high 170s, off the pace but perhaps close enough if lots of cautions, 7 hour races or off sequence racing. Several of these cars do not use a cell, which you can sort of figure out why if you stroll through the classified and buy one of these cars that happens to be for sale..... So does fuel capacity really represent this large of a performance detriment? Not that some stroke of luck, a good call, or some other act can't result in a win, but do you think the numbers represent or approximate the real odds of winning outside of the 160-170 lbs per gallon "wall"? I wish I had sorted out tracks with really low or high fuel burn, which wouldn't change the # of stops for a good vs bad fuel capacity car. Assuming these non typical races would make life easier for a bad capacity car, they still don't appear to be winning much anywhere......

    Team PartsBadger – Road Atlanta Recap Firstly a big congratulations to Pinky’s Out for first place – The Car is FAST in the corners and very well driven they were great to race with and ran a great strategy. Congrats to crowd control racing as well, it was a fun race chasing Pinky’s with Crowd Control breathing down our necks. Also congrats to the 626 team on the B class win, its awesome to see that car put up a solid performance. Congrats to NotBannedYet for setting the bar with a blazing time! Secondly I would like to apologize for the contact in practice and then again in the race. I am 100% at fault and learned a lot this race about how to drive clean. The contact in practice I thought the door was opened and it was not. In the race, I committed to the pass when I should have just backed out. Both were lines I didn’t expect, but they are 100% entitled to those lines. I’ve already changed my style greatly after Sebring, but clearly, I needed more work. Everyone has their right to own their own line even if it’s not the “race line” or “fast line”. A lot of racers are just getting started and they pay just as much as I do to enter a race and are entitled to drive their own line. It took me far too long to realize this. A big thank you to everyone who helped us get our first podium. When we first bought the tired ITA car we had much lower ambitions but it quickly escalated to us wanted to build a top car. We bit off a little more than we could chew before Road America in October 2018 and had a number of mechanical issues. Sebring was another learning experience for us both in car prep and driving style. Low Tide Motorsports was our crew for Sebring and quickly identified many things we were doing wrong. They did a great job at the race and allowed us to get a lot of needed testing done on day 1. After Sebring we added a phenomenal mechanic, Will O, and spoke to some veteran racers(they can name themselves if they wish) who offered great advice on everything from fueling, physical and metal fitness, car prep, and driving style. We took the advice and rebuilt the entire car before Road Atlanta with the goal of just finishing the race. We arrived at Road Atlanta and all of us were in awe of this AMAZING track! The elevation changes are shocking. Although we all watched a few hours of videos, nothing could prepare us for the first time cresting the hill before turn 12. We burned a lot of practice time bedding in our brakes on the skid pad and chasing some odd tire temps realigning our car between sessions. For the last session I made contact within my first few laps with the 626 car and we were blacked flagged for the day. I was still too green with the track so our third driver Chris Prey would take our first stint. We also didn’t have a lot of time to test our pit stops and were worried since the dry run didn’t go so well. We also didn’t have time to really test our radios. We decided on a 9 stint strategy providing us the most flexibility in pit windows and we wouldn’t have to worry about fuel. If we did it right we could get a couple yellow pits. When the race started Chris was running fast, consistent and clean. We were hitting what we believed would be solid times. Unfortunately, our pit couldn’t communicate with our car for some reason. That said we hit our first pit window during a double yellow and we had a perfect stop, so far so good. Our second stint starts in the video below. I was learning the track and there was a lot of traffic, but near the end I was running good times and the car felt great, then I foolishly attempted a pass where I shouldn’t and made contact with a purple miata. We spun and I ended up de-beading the passenger side tire. I was able to get the car into the pits, and the double yellow dropped due to the incident (AFAIK). We did a great stop and replaced the tire and then were held for a ~5 minute penalty for the contact. We lost about 4-5 laps while being held and dropped from the top 5 to 10-15th. Jimmy started the next stint and was running strong getting spots back. Near the end of his stint he was coming over the 11 crest and saw a yellow but was going too fast and couldn’t slow the car in time. He was black flagged the next lap for passing on the yellow and came into the pits, luckily during a pit window again. He was held for another 2 laps until released for the our pit. We had another great stop and some yellow help and Chris began going to work getting our spots back. We had a lot of green over the next two stints and made up significant ground as some of the leaders dropped out. We had an oil scare and lost a quart during a stint which ended up being a valve cover breather. Luckily our crack mechanic was able to make a catch can and keep it together while still hitting 5 minute stops. We still adjusted our shifts to 6500 and were on edge the rest of the race hoping it was just the breather leaking. We were running strong but during the second to last stint I hit the backside of the curb at the outside of turn 3 and the wheel began vibrating violently. It didn’t seem like a hub failure and the grip seemed ok, so I marched on for the next 15 minutes until our final pit window opened. We did our final pitstop and our finish was in Jimmy’s hands. He was turning strong laps and we were hoping we could push Pinky’s Out into a fuel issue while also keeping Crowd Control behind us. Towards the end of the stint, reality hit that we would finish, and finish on the podium and I began frantically looking for our tech sheet for impound. After half an hour of searching I finally asked registration if they have new ones and there I saw the stack of tech sheets. I didn’t know they kept the sheets LOL. The Checkered flag dropped and we had finished our first race. We got to impound and Jay told us we’d need to remove the valve cover and we grabbed our tools. Once we started to remove the cover we were also asked to split the intake manifold which we did. Jay then asked me to remove the gears to see if the I / E positions were correct, to see if we did the Exintake swap(I know of it, but not the details). We removed the front cover and were trying to figure out a way to remove the gears without losing our cam timing. Jay asked us to find pictures of the cams to prove they were legal and Jimmy was searching for pictures on his phone. At this point atleast one team was telling us to just give up and go to EC, showing me values from an out of date VPI sheet. At this point the excitement from the podium was gone and it started feeling like a mob with pitch forks (reality or not, its just how I felt at the time). We zip tied the belt to the gears and removed them from the cams to show proper position. Then we were asked to remove spark plugs and they inspected our pistons. Huggy, Jer, and Troy had some kind words during impound which was comforting when we felt short on allies. A couple minutes later Jay called everyone over and gave everyone the opportunity to speak now or hold their peace. There were no takers, the race was called official and that was that. The trophy presentation was late with a light crowd, but we were elated with our performance and our awesome new hardware. After the awards, our car was the only one left in the pit lane and we began gathering our things and taking pictures to celebrate our first finish. Security came over upset since he wanted to get home but needed to lock the gate, so we threw everything in our truck and towed the car back to the pits. We enjoyed some very smooth whiskey and beer with our Miata pit neighbors and hit the hay with our stuff spread across the paddock. We got up at 8am lightly hung over and began packing our crap for our 13 hour drive home. After some black ice in Indiana we finally got home around 5am ready for work 3 hours later. We all learned A LOT and are in the process of getting the car ready for VIR, hopefully with a few upgrades. We do plan to help our Miata brothers by sharing what we’ve learned thus far, and we have a lot more to go. We are also working on a software tool that calculates pit windows for yours and other teams, average lap times and standard deviations of lap times during stints. This will help teams see when other teams are pitting and calculate gaps and target times for the remainder of the race. We are also developing it for ourselves to use as a post race analysis tool. This should be done soon, maybe we will have a beta in time for VIR. I’m not sure if something like this exists, but if there is a wish list, let me know. We are using the API from MyLaps I believe so any of the raw track data should be available. Stints 2, 3, and 4 – Contact during stint 2 - At 1:13:45 Contact During Practice:

    Sorry I chose an example specific enough to be linked to a single team. It's still valid to question the success of a platform as a proportion of wins/podiums to number of entries as opposed to just the total number of wins/podiums.

    You’ve taken a guess at weight, what you don’t have ( I don’t think). Is how much fuel they actually have. How many have cells? How many have modified vents on stock tanks ? How much does that gain? If they couldn’t do that would the results shift? How much additional is being added with long 3” fill necks? What your working toward has merit, but may have some unintended consequences too

    Nice recap and great videos / video quality. Your video really shows where your car is great (turn 1.... so many passes in turn 1!!, esses, 10b) and also shows the cars that walk you down the straights. Just know that people will continue to point at lap times and call you cheaters... buckle up and get used to it because I see a lot of podiums in your future. Haters gonna hate.

    We should be able to aggregate all lap times and determine that if there's a statistical anomaly it would be a yellow.

    Exhaust. Our drive train is proven. Our first race was comical. Black flagged twice for hanging exhaust. It will not happen again. Seriously reinforced. And a rear brake bolt came loose. Lock tight and attention to details on remaining bolts. Rocker arm broke after a down shift into first instead of 3rd. As far as driver issues we were not fast enough to really make a call.
