  2. I realize this is my first post, but after wasting the better part of an hour that I will never get back reading this mind-numbing thread. For those arguing that the density of fuel effects the ChampCar volume measurement: I would like to know which dimension of the fuel cell changes when you take your car from Florida to Wisconsin? I don't care if it's measured with fuel, golf balls, or hot dogs, the dimensions of the container would have to change in order to measure a different VOLUME capacity with a fill test. In fact, if it's a rectangular cell I can easily measure the volume without fuel at all using tape measure! Fuel density vs. temperature shouldn't even be mentioned in a ChampCar thread because there is nothing in the rules about fuel weight or mass in the rule book.

  3. I am still in the hospital and have at least 12 days left. Covid. I was a coin flip to live when I came in. I’m on the mend but it’s not over. Anyway, I have decided I will not run again. It has become more tedious and less fun for me. Losing Doc was a huge blow but beyond that I’m reevaluating my whole life right now. I’ve offered up to stay on a Treasurer moving forward because I love this org , the racers and all the people involved. It will be up to the Board if they want to retain me as Treasurer. If they don’t that’s fine too. There are some fine people running who j believe will advance the series and make it even better! I want to thank all the members for their support and votes in the past. It’s been an honor to serve and I appreciate all of you. I still plan to race next year, although this experience has taught me to change my priorities. Two-three races at just my very favorite tracks! Life is short. Smell the roses.

  4. Local restrictions, we cannot start any racing until at like 12:00 noon, or maybe 1:00pm on Sunday. Makes it hard to get a full endurance race in starting that late. Dana

  5. Reading comprehension fail. Let me try again another way to help you. In an amateur series, which professes to let people come race without "obscene" expense, the rules should prevent teams from gaining advantage from spending. Currently our rule book doesn't do a good job of that. Therefore we currently rely on people respecting the "spirit of the series". Each team's interpretation of that is different. If you used to run an IMSA team, spending $50k in a weekend is racing without obscene expense. Unfortunately, for about 90% of champcar's customers, the weekend cost is way less, so $50k is an "obscene" expense. Just because you disagree with me, doesn't mean my statement wasn't well thought out. I was elected as a board member with the platform that I would speak up for the lower budget teams. I want to prevent champcar from becoming WRL or AER with how much those series cost to be competitive. Yes, champcar currently offers the opportunity to go racing with your friends and family without obscene expense. However, I want to ensure we continue to offer the opportunity for teams to actually compete without spending their way onto the podium. Should it be easy? No. But with effort and experience, every team should have the opportunity, and the second spending becomes a requirement to compete for the win, we have failed as a series. If you feel thats wrong, so be it, but I won't back down from speaking my mind. I owe it to the members who voted for me with the understanding that I would speak up when necessary. So yes, there are a few teams who I feel don't respect the spirit of the series, and who would be a better fit for WRL or AER. We don't want to lose customers, and it's not personal, but by those teams participating it provides an image that is not in line with the perception we should be outlining as a series. There is an opportunity cost there, and if perspective customers (or current members) see those cars racing and succeeding, they may choose to race with an alternative series (or not race at all) as a result. There are tons of teams who spend more than me. Ask the guys who race with me, my rates are reasonable and my cars are "built, not bought". We race on the same set of tires all year - budget is definitely a concern. So no, every team who spends more than me is not who I am talking about. So, in summary, you are a troll hiding behind your keyboard. Good Day.

  6. yes. You want like 10-20 accross. example 140-150-150 pressure too high 140-160-150 pressure too high 140-130-150 pressure too low 140-150-160 even from step to step, sooo yummy Also, you might find your car and tires size likes 12 degrees across 140-146-152 Or it might like 18, or 24, or 9. That just depends on the tires size, how hard the car is on tires, ect. You need to find what is best for your setup, though being even across is best. The easit way I found is camber will do the outside and inside numbers and get those right first. Then fine tune middle to make it even. I usually use 24-27 psi cold pressure to start with and go from there. Then adjust and after it is right and good and cools down you know what your cold pressure should be at Temperature X. Then adjust as needed. Meaning if we start the day at 40F I might drop the pressure a degree to two starting and go from there if we use 70F as a baseline.

  7. Thanks to the Champcar officials for a great weekend. It was our first ChampCar race, and first road race for that matter. Special shout out to Team Infinity for all the support and help though the weekend and the +2 years of motivating me to keep going with the build. It was all worth the effort. We had an awesome time and will be preparing to up our game for the Sebring race in December. Pros: - Had awesome time, far better racing than we expected and just overall great experience - We had some solid laps and decent times for our first race; drivers were all happy with the car (when it ran on all cylinders); actually made it into the top 20 on both days when we had a good run. - Finished under the checker both days - double bonus!! - Learned a ton, which was the goal - Made some new racing friends Cons: - Had to swap out our trans on Saturday with our spare; ate up over 3 hours; then the shifter decided it didn't like the new trans and departed this earth - replaced and got running again - Fought a cooling problem on Saturday and pulled the hood off to resolve - ultimately swapped out the radiator with a replacement and solved the problem for Sunday - Valve train issue end of Saturday turned out to be missing jam nuts on a couple rockers - found 1 and the other is MIA. Installed nuts, set the lash and crossed fingers the one homeless nut found it's way to the pan or innocuous location. - After our first 2 hours on Sunday we dropped a cylinder - after repeated trips to the paddock and having isolated to a bad injector we sent out the drivers to finish out the day on 75% power. Lesson = the one spare you don't have is the one that will pop up. - Had one incident with the red firebird when they passed where there wasn't enough room (apparently) - ended up with a rub down the pass side but not too bad. I haven't looked at our video yet to see what actually happened. Again thanks to the Champcar staff for a well run event. The T&S issue on Saturday we understand the pain.....been there ourselves in kart racing. Thanks for working out to let us run until 7PM. It was very much appreciated.

  8. On Second Thought 341 Miata Race Recap Longer drive up to MidOhio from Nashville than we were expecting, had a few slowdowns on the interstates and such. Rolled into the track around 5:15 on Thursday, we parked the truck/trailer and went out and watched some of the track day activities going on. Wanted to get a little lay of the land prior to getting on track Friday. The track has a lot more elevation change than we expected. Friday was the first time any of us had been on MidOhio, had a new engine in the car, and first time with a rear wing. We spent most of the day getting 20-30 min stints in for all of the drivers to get familiar with the track/car. At the end of the test day all of the drivers felt pretty comfortable with the track. We decided not to participate in the sprint race, and watched it from outside of Madness. We were impressed and discouraged by the lap times that most of the sprint guys were running. Decided to cut out of the track and grab some gub. We normally pick a Mexican joint, so stopped by Tito’s in Lexington. It wasn’t quite the same “cheap” food we were used to, but we would recommend others go there in the future. Good food, good Margs, all of us ate way to much the day before getting in a racecar for 8 hrs. Saturday started off with me in the car. We were toward the back of the pack at the start. I had a pretty uneventful start and first 2 hrs. The car clicking off laps like normal. Second driver got in, and much of the same, laps went by, no issues. Third driver gets in around 1, and third lap out someone tried to pass him on the inside of 9 under the Honday bridge and tagged us in the left rear wheel/quarter. He spun out and ended up facing the wrong way. Brought the car in to check things over aside from some wheel damage things looked ok. We had another unexpected stop a few laps later due to temps creeping up on the car, found a bunch of grass had gotten up on the front of the car blocking the radiator. Back out he went, finished his stint without any other problems. Final driver got in and was out clicking quick laps, set FTD for us around 4:15. Got a call on the radio soon after that something on the car broke. A few min later he comes pulling into the pits with the RF ball joint broken on the car. We brought the car back to the trailer and called it a day. This is only the second DNF for the car out of 25 or so races, so we were a little disappointed in the result/finish… but its bound to happen. Got the car all fixed up (always bring spare parts for everything!!) and ready for Sunday. Finished the night off with some cold beer and good pizza @ Fast Eddie’s in Bellville. Sunday morning started off around 20th or so, the whole day was pretty uneventful with us. Clicking off quick consistent laps, our times aligned really well with our test day, which means the pace was pretty good for us. I got in the car last, unfortunately we pitted about 5 min early for a FCY which would have been great to have hit for the driver change. Ended off finishing the day in 13th. We were happy with the result considering we had the 28th fastest best lap time, with only one other team finishing better than us with a slower best. Packed up the truck and drove all the way back to Nashville after the race, getting in around 11pm local time. Made for a long day! Sunday was a great finish to the weekend. All 4 drivers were very close for lap times and consistency. We all really like Mid-Ohio, had a blast when we could actually do some open lapping. The track is however pretty difficult and discouraging to race at when you have a hp disadvantage. I can’t tell you how many times we would catch cars between China beach and the front straight but couldn’t make a pass on them due to lack of power. Then get after turn 1 and they just pull away and gap you all the way back to China beach, the. You have to do it all over again. We definitely had to earn some of the passes. First race in a long time that an extra 10-15hp would have probably made a significant change in ability to make passes stick. Got back from the weekend found some metal in the oil, engine was pulled out of the car by Tuesday nightfor inspection. Looks like nothing serious, so throwing a few new parts on it and we should be back up and running for our next race at AMP.

  11. I disagree. With all the experience I have and helped build a lot of cars I have never seen an advantage to an alum radiator in a race car, actually the opposite for lap times. On the street, maybe, on some turbo cars with a giant intercooler before it and ac heater core it heats up the water a lot and can overheat. That is mainly due to slow street speeds and poor ducting. In a race car, at speed, that should never be an issue. Here is why an alum radiator is a detriment to a race car. Weight. Every 10lbs or so can equal .1 a second, give or take. We took out 280lbs of the care one summer and gained 2.5 seconds a lap. An alum radiator is almost always heaver in two ways. The alum ones are larger than stock, so more alum is heaver. I have put in alum ones and they weigh more. Then you have more fluid capacity and fluid weighs more. On the turbo setup, use some good ducting. Please share your setup and we will help you out. I assume you did not route the intercooler hot air into the radiator for a race car setup and both have their own fresh air. To me, and please do not take this wrong, if you are choosing to use points for an alum radiator instead of a wing then you are not setting your car up correctly. If you share you setup, you can pm if you want to keep it private and I will not share it, but you should never need an alum radiator. Let us help you.

  12. I had an ecotec Miata as a daily and it would overheat the stock Miata radiator on the street. It had pretty poor ducting which probably had a lot to do with it. My main point is that there is a competitive advantage to an aluminum radiator. If you could swap your stock radiator with an aluminum one and then tape 50% more of the grill, you could have less drag and therefore more speed. Just because everyone doesn’t do this doesn’t mean it isn’t done and isn’t an advantage. Our second car is getting it’s first outing at Harris Hill. It’s a turbo Miata and will 100% require a big aluminum radiator. Now that we don’t have to pay points there, we will likely be adding a wing.

  15. lo Sure! But, the nice thing about roll plastic is that you don't really need to do the cardboard step. Same way you cut and trim cardboard, you can do with roll plastic. I have recently changed how my splitter is mounted and now use the splitter mounts as part of the ducting. I also use the brake ducting as radiator ducting. Here comes pics....

  17. OK, I will give a race report from the sprint race. Practice went well, and we were taking the Tuttle sprint race way too seriously. We had the car all setup and ready to rip with a set of Maxxis VR-1 tires that were scuffed in for 2 laps that same day. We had just enough fuel in the car, no cool suit cooler, etc. etc. Drivers had special starting procedures, and were told they had carte blanch for the race. We asked for help from Andy at@mostmint with the pitstop, and we were all set ready to push the car to the front of the grid as soon as the practice day ended. We push up to the grid ASAP when the checkered fell for practice, and got the poll position we were hoping for. About 10 minutes before the cars were released Brian Tuttle asked if we were paid in full and registered for the ChampCar race. I headed up to registration, where everyone was super accommodating and let us get registered in a matter a minutes. By the time I got back to the pits, the cars had been released on track. Green flag dropped, VTEC kicked in, and we were in the lead going into T1. Our favorite Pizza delivery driver put on a clinic running basically all 1:40.XX laps until his driver change was up. Driver change went flawless thanks to help from Andy, and we were back on track in a matter of seconds. In the 2nd stint the orange Glazed and Confused Miata began running us down. They were on our bumper with a few laps remaining, and the overall win looked like it was in jeopardy. The orange Miata went for pass on the outside of the carousel leading onto the front stretch, but could not hold the pass and spun going into the grass wide. The Miata was able to return to the track without sustaining any damage. We were able to breathe again, and ran the last few laps with a comfortable lead until we took the checkered flag. It was all smiles and high fives until @Bill Strongpublished the incorrect results. The Friday test day and sprint races were a great time, Thank you for setting that up Brian Tuttle. Other than the @Bill Strong blunder, the entire day went great.

  18. The Chunkysalmon Focus team had a great time! We have been working on this car (a 2008 Focus that I bought new in 2007) for about 2 years on and off. All of us work on or around cars for a living so it has been a struggle to find extra time to work on the race car after working on other cars all week. We prepped the car and trailer on Thursday, and on Friday arrived at the track and went thru tech. Tech only found some very minor things for us to address, which was a huge relief, because this is our first race with ChampCar, and our first time building a race car from the ground up. Saturday went well. We met our two goals for the weekend: Finish a race, and everyone gets seat time. We noticed how slow we were early on, and throughout the day started coming up with a list of things to change on the car over winter (not enough tire, too much body roll, etc.). All in all, we didn't finish dead last on Saturday, and the car didn't break. Sunday we only made it about 3 hours before the right front wheel hub broke. We knew about this possibility on this car, but decided not to pack spares (oops). We got a chance the rest of the day to walk around and look at everyone else's setups to see what we didn't think of, or what might be useful to us in the future. We had a blast and learned alot, and everyone was very eager to answer questions and just be friendly in general. Thanks to Money Shift Racing for selling us the roll padding and clamps we needed to pass tech!

  19. Aluminum radiator provides more cooling capacity. We can close the grill area to reduce drag while maintaining temps. Another thing here is when drafting another car for multiple laps, temps with the stock radiator shoot up and you have to get clean air or back off. Car is a swapped Miata. If it had stock power, stock radiator would be fine but then we would be slow.

  20. Another car here that pays points for an aluminum radiator. That free 10 points means I can now afford a header or intake manifold. Few more hp and faster lap times. Definitely no speed/cost creep /greenfont

  21. For those concerned with speed creep I've got bad news for you: it's only going to get worse. Freezing the current rules won't help, because IMO most cars and drivers have many seconds left in them. Think about all the time you have left on the table vs. a pro driver in your car. Then think about all the aerodynamic components you could make with repurposed material, all the porting you could do, how much weight you could remove, etc. The ruleset makes optimizing a ChampCar very difficult, so it's taking people a while to figure out how. The result (plus driving improvements) is consistent speed creep. Slower cars tend to have their VPI reduced, which does help them. But this does not help the faster cars who tend to have their VPI increased. Some freebies like flywheels or whatever do help free up points, but not to the tune of seconds a lap. Aero can help quite a bit, but it's probably under-valued in the current rules.

  22. Late to the party, but I feel compelled to chime in as the topic is near and dear to us. We tend to be the slowest car out there as far as “fastest lap” goes. Basically stock E46 325xi. Yep, all wheel drive. Cold air intake, cleaned up exhaust, sport springs and struts. We keep our heads on swivels, drive predictable and try to stay out of the way. We start 5 laps down and have a simple race strategy: no penalties, stay out of the garage, don’t hit anything. Our fastest lap at Thompson was the slowest of the field and we finished 17th. We had a similar result in the VIR24 a couple of years ago. I agree some driver education will help you get comfy and the more seat time the better. Don’t skimp on safety. Come out and race. The view from the mid-pack is outstanding. Cheers, Bob

  23. Probe lengths are often adjustable if you unscrew the tip. The 10-20F spread rule of thumb is, IME, usually BS. We went from a 15-20F spread in front to 25-30F and picked up a lot of front grip and more even tire wear. Granted a lot of this depends on braking. Lots of slip (ABS) will heat up the insides a lot more, especially in the front. We found the rear seems to like less spread, probably for this reason. As you found out, probe placement is super important. This is another reason why I don't think the rules of thumb tell you much. I've been meaning to make something that lays across the tire so I put the probe in the exact same spot each time. I've run a spread of tires pressures, 30 to 40 psi in 2 psi increments (on a heavier car), taking daq and temps each stop. There's not much time in optimizing pressures. The car will be sharper with higher pressures but develop a bit less grip. With lower pressures it'll feel like crap, but if you can drive around the slower transitions it doesn't hurt you too much. On a stiffly sprung car pressures can be used to fine-tune balance, since the tire spring rate has more influence on the total wheel rate when the springs are stiffer. It's up to you how to interpret right-side data on a track with mostly rights. Sure it looks like you need less camber, but those few left turns might be really important? Or not. If you're 1.5s behind I wouldn't worry about fine-tuning camber and tire pressures.

  24. Good Afternoon fellow Champs! For those who don't know me, I am the owner of Speedway Creations, and I'd like to recommend Ed Steinhoff for nomination to the Board of Directors. Ed has been with ChampCar since the beginning. He basically was there when the big bang happen if you will. His brother Jake and he starting racing endurance events after their numerous circle track days and found something they could do and enjoy. Their team, Team Infiniti, is an unicorn in the series, but make no mistake, as a full time mechanic, Ed knows his way around a car, just about any car, and that's just one of the reasons why I think he would be a perfect addition to our Board. He runs a competitive team, knows what it takes to be a front runner, and knows what it takes for an amateur team to race with this series. He knows cars, but has always been willing to ask questions and listen to answers or suggestions. He has been around the since the beginning and understands the roots of the series, and can lead us into the future with respect to the past! Please nominate Ed Steinhoff, member 000160 for ChampCar Board of Directors. STEINHOFF 2022! HE IS QUALIFIED, BONAFIDE, AND HAS THE EXPEREINCE WITH CARS AND THIS SERIES TO KEEP US "ON TRACK!"

  25. They are originally on the car; no new apparatus is being added. You can alter the range of adjustment by slotting the subframe and either increasing eccentric washer offset or welding a different stay for the washer to ride against. You could also use a non-adjustable slug? Not sure if that would qualify as a fastener and thus be points-free or not. Or just do an old Spec Miata trick and bend the upper control arms...

  26. The biggest reason we chose an NC Miata was the number of other people campaigning them. We reasoned they couldn't be written out of the series (my last ChampCar build became 600 points). It is 1950 lbs full of gas, by the way. The roof and windshield removal were probably a mistake. It saves some weight but prevents you from venting the hood, which is a big reducer of front end lift. It also increases drag, even with all our attention to minimizing things in the airstream. Most annoyingly it prevents me from running WRL with the car. I still vastly prefer it to a closed car, but a lot of that comes from getting CO poisoning and generally overheating in closed cars. CMP is a low-speed track so it's possible the roof removal is advantage there. But again I don't know why CMP lap times are relevant? There were no fast cars there. No MK or WTF like were at our other races. The Danger Racing SC300 probably could have challenged us had they not of hit a Miata. We could go 1:47s conserving fuel to last two hours, while I think they did a 1:46 obviously not needing to conserve. And that car should be making more power IMO. The lack of full-course cautions really hurt us. Bone stock, flat shifting every gear my NC ran 15.4 @ 91.9 mph. I tried to include the PBox pic but it's keeping this reply from going through. Now I think it's 13.6 @ 102. E30s are literally the worst RWD chassis I can think of. I don't know why people like them. Edit: Ok, the fuel advantage is nice given ChampCar's 5 minute fuel minimum. If anyone needs help getting faster, they can just ask. We freely share data and advice. We'd love it if the pace of ChampCar races increased; then we wouldn't need to go to WRL. Yes you need an unhealthy obsession with weight reduction to build a fast ChampCar. This is part of what makes the series great, because light weight is the only way to go fast cheaply. There are no other options.

  27. We have left the series and have withdrawn from the races we were registered for through the end of the year. We have $2550 in winnings currently in our account and are looking to sell it to another team or teams. I've gotten the blessing from Dana to do this so this isn't a backroom deal. He set up 2 separate $1275 credits in our account. You can buy 1 or both. $1200 gets you $1275 in Champ credit. PM to discuss the transfer.
