  1. I think the last 3 posts demonstrate why the rule book is difficult. The board, tac, and tech staff can't win when no answer makes people happy. We can't rationally be complaining about a change of rules and then complain again when they switch back 24hrs latter.

  2. Limited prep doesn't work anymore. Too many people have figured out how to make cars fast, and too many people want to be competitive. Even LeMons isn't limited prep anymore if you want any chance at being near the pointy end. The idea of limited prep worked just fine in 2009 when nobody had really developed a car for this type of racing, and everyone was running whatever junk tires they could scrounge up. There may have been a few years of limited prep, but the horse is out of the barn now. Any series that starts up will rapidly devolve into heavily prepped cars bec

  3. Sure! That rule was originally written to allow teams to buy a cell in a standard size up to 2 gallons over stock and displace back to stock. The rule wasn't clearly written and the interpretation of just a points free 2 gallons has stuck for the last 8 or so years.

  4. Here's an unpopular idea: No minimum pit time at all, which would have a couple of descending effects. Since the driver can be changed during fueling, the driver and fuel usually take about the same time. There are some cars that fuel very fast but the driver change is still finished before fueling. Also, the car cannot be worked on during fueling, so changing tires would penalize a team a minute or two to do so. Say the fuel and driver takes 2min, and tires takes another 2min (easy numbers). Normal stops would take 2min ish, but an extra 2min would be added if ti

  6. There are many ways to approach the tire situation, but many just don't work out well for our series. 1) Tire exclusion list: too many changes, too much maintenance, there's always a "new hot tire" 2) Limit number of tires per weekend: tech has to mark tires, too much work/time in tech now, then someone has to check the tires in pit lane to see if they are marked - enforcement disaster 3) Add time to tire pit stops: again, enforcement hassle / impractical 4) Pit only for tires separate from fuel: too punitive to those that want to use up old tires The only pract

  7. ChampCar races at Road America never disappoint! This one started out rough for the Premium Dudes, as I've said a few times, the BMW had last minute issues and we had to call an audible. Fortunately, Andrew maintains the RBank CRX and gave the OK to run it at RA. I work on this car from time to time but have never driven it (I have unique skills like fitting under a dash and wrenching upside down). We got to prepping and finished it up Thursday night, loaded the trailer, and headed to RA on Friday. First things first... The CRX is impressive and driving it was a great

  8. WRL is different because there is no minimum time on pit stops. Every second spent changing tires is seconds you aren’t turning laps. In ChampCar if you can change tires within the 5 minutes, there is no penalty.

  9. I'm not suggesting limiting the number of tires at a race; that is too hard to enforce. I'm suggesting only allowing 4 tires (including what is on the car) in the hot pit at a time. So you need to take the tire off and put it over the pit wall before you get another. Kind of like refueling. This slows down the speed of tire changes just like hand tools and results in a time penalty to change lots of tires.

  10. Shortening the min pit stop time to less than 5 minutes would also limit the effectiveness of running a quicker tire with shorter life (while also reducing the penalty on cars that can't go 2 hours on fuel)

  11. Same hp weight formula applied to all cars. Just like the swap calc already does. Sample Model Heads .25 Cam .2 Intake .1 Carb\Throttle Body .1 Header .1 You add up your multipliers. So a motor with heads, cam, intake, header is .25 + .2 + .1 + .1, or .65 You take your engine's base power, and add .65 * it. So if you have a smog era 200 hp engine it is now 200 + 200*.65 = 330 hp

  12. 1990 rx7 13b swap calc weight is 2797. The lightest 2nd gen OEM curb weight is 2696, which should be about a 2450 lbs swap weight given the typical 10% reduction in swap weight from curb weight (but often applied to the heaviest convertible model, not the lighter model people race). If that thing weighs 2800 race weight no wonder you burn brakes off.... FWIW you could do a 200 hp 5.0 swap in a 1990 claimed car for only 2 points over the min swap fee. Same for 3800, with a cam might be a great combo. Point being, you still need the trifecta of VPI, Swap we

  13. The rule didn't really change wording much, if at all. However, the discussions about fuel cells made it clear this rule was just to allow people to buy an off the shelf cell versus getting a 15.7gallon (or whatever) fuel cell made. This was probably around 2011 or 2012 would be my guess.

  14. "If you change it, it will break" This should be the mantra of endurance racing. We've done a total of three test days to prepare for this race and the national championship. After Gingerman we made the decision to move to a hot tire and purchased 205 RE71Rs, 245/40-17 RE71Rs, and 245/40-15 Rivals after running the RS4 since the car was initially built. Tire testing was inconclusive other than the hot tires are faster but the 20 minute sessions of lap days didn't allow us to get the grainular data we needed. Normally we run very low pressures (19 cold) and little camber (1.8 to 1 degree

  15. So what i experienced on Sunday when I ran the DE at Sebring, they took our temps to get into the track. We then had to get out of our vehicles as there were a list of something like 10 questions we had to answer. Once done, we had to sign two waivers. All of this was at the main gate before even getting into the track. Not saying it'll be the same next weekend, but I didn't pay the extra $20 because I had an open trailer. I have seen all kinds of pit vehicles there. Given that added distance we now have to cover with fuel jugs, I'm bringing my old Polaris to help with setup a

  16. Castrol Prefect Racing Report - THE CHAOS WEEKEND Team artist dressed up the side skirts prior to this weekend. Man, did she ever get it right. Practice Day: Car shows up ready to race without any last minute buttoning up to do so we can relax and put in a couple laps and go to bed rested. In less than an hour of practice time, the driveshaft coupler is ripped apart. At least we got to test the pit cart vs the race car on track before that happened which was pretty fun.

  17. Or maybe the BOD can accept a tire petition and reign in the tire costs. How many tire petitions need to be submitted to the BOD to get a single one approved and for how many years? 10 ? 20 ? 100? Petitions. How many times do we need to try to put a tire petition through to actually get a change made? The members are asking for it and you all represent the members as a hole and need to think long term about the members and organization. I would also like to see a specific list of what board of directors voted what way on each petition. I think that would be eye opening on who wan

  18. I did multiple tire petitions this year and none go approved. I did restrict certain tires, laps for certain tires, if you change a tire you get X amount of time penalty, only one tire change at a time. I tried, but failed. All denied.

  19. this is something people don't understand. I've seen so many people post about how the car has been in the trailer 3 months after the last race and they will fix it up weeks before the race. I'm sure other teams are the same way, but I will empty the trailer the day after the truck gets home, put the car up and do a 2-3hr inspection and start a list on the white board of what needs to be addressed. Then i spend 2-3 hrs every day after work in the shop tinkering on the car, and basically every weekend. Thankfully my wife has been extremely good about it, I have to take her out to dinner a

  20. I already posted this in another thread, but it's here now as well. No minimum pit stop time. This has more effects than just tires, but I'll get to that. Since the driver can be changed when fueling, most all teams have the driver in before the fueling is finished. Changing tires has to wait until the fueling is done, which would add time onto the pit stop. If fueling takes 2min and tires takes 1 min, every pit stop will be 2min unless you change tires, then it would be 3min. This would also negate the need for the people at the end of the pit lane. I know

  21. What do you mean by hand tools? If I have to spin nuts off with a cross wrench thing, I’m out. I don’t like “gimmicks” to slow down tire changes. If the goal is “change fewer tires” make that the rule. Don’t make the rule something else which you think will have the effect of “change fewer tires”. If you think “one set of hand tools only” will make it impossible to change more than 2 tires in a stop, and that’s what you want, you should instead make the rule “max of two tires changed per stop”.

  25. The only reasonable recommendation that I made was to limit total tires allowed during a race. Here is where I made that suggestion. Admittedly, it also still has flaws and could be exploited.

  26. Chris, What do you suggest as a solution to the tire cost problem we have currently in the series? I see you bringing up good points about possible issues with ideas, but I do not see any solutions brought by you, but I might have missed them. Or do you think we should leave it as is? What about teams that can spend 2-5K a weekend on tires vs the guys who can only afford one set of RS4's for two races. Should we simply give the teams with all the money that 2-4 second a lap advantage?

  27. Or "dual branded" tires, where they change the label to enlarge the market. Auto x guys know what I am talking about, having legal and non legal versions of the same tire that simply have a update to the mold stamping. Ahh, bringing back memories of the "street touring" classes

  32. Unlike the other races we have done post-COVID, there is not a link for the waivers. Unless otherwise updated, I believe these are provided at the front gate at the base of the bridge to the paddock. There are no weekend memberships. These have been eliminated all year at every event we've raced. Unlike some tracks, Sebring has a very liberal policy with pit vehicles and would not expect that to change. Also, there is limited power in the paddock, and in particular lighting and hookups on the concrete are very limited. You should bring a generator if you need this at your tra

  34. My thought is this. In the 10 years of racing CC and 10+ races a year I have not see a car overheat due to a stock radiator. I have seen them overheat from terrible boxing in of the radiator so an aftermarket one would do the same, but that was years and years ago. I think we have figured it out now so radiators are a non issue on performance. We run a stock rad and see the same exact temps all the time and even NCM when it was 107F that day. I see it as a cost saving item that could be addressed.

  36. Every person who races knows that certain tires are 2-4 seconds a lap quicker and last a single day at best, a lot of times less. This has a cost of $2000+ per weekend extra for teams in most cases. We know the tires, we know the brands and we know what it does. We need to have some rules for it. No rule is perfect, but measures need to be taken and put in place. Sitting back, making excuses as to why a rule is not prefect and therefore not good is not acceptable in my eyes. I know you want to put rules forth to keep costs down from our conversations and are shot down. Most member

  37. right, this would be a problem with our 1990 Audi, which I believe came with 185's on 14" wheels.

  38. Again, this would be a no go for basically all old cars. Use the early gen Mustang for an example. 195/75-14 as stock... yet you can put 245's and larger under there. Other cars that may have used tiny 13" rims and 155 or 165 tires as well. This is a situation where modern car designs start with much larger rubber to begin with.

Bourbon, cigars, finished putting shelving in my basement (although I'm still sorting things to put back in totes), built/rebuilt a new PC, and spending WAY too much time playing Modern Warfare. This was my first time doing any sort of PC water cooling and I have a new GPU coming whenever EVGA gets around to shipping the 3080 FTW3 cards again, so I will be redoing the loop when that comes in and a waterblock is available. Disregard the extra 8 pin PCIE connector, when I put everything in the new case I decided to run the wiring for the 3080 instead of just doing 2x8. I plan on picking up a

  43. Epic update: I know its been a while since the last update. Basically for the last three months I've been worrying myself sick trying to prepare the car for PIR, and studying for the PE exam (9.5 hours long) which is the day before we tow the car to the track for tech. Impeccable timing! I know it's not Champcar, but the car's first race was last weekend at Portland International Raceway with LDRL 8+7 with 45 min. night sprint. Figured it's appropriate to report on this thread anyway. This is where it all started for CC back at the 24 hour race on Halloween 11 years
