  1. I'd also add to not just take other's recommendations as gospel, even if its a similar car/build. Brake pad compounds are like ice cream, everyone has their favorite flavor and what's good for one build is not always good for another. Listen to other's/mfg suggestions, look at what you have and what you like/dislike and use the info to make your own choices. The unfortunate part is that it will take a good bit of trial and error (and $$) and needs to be done at track speeds. But, IMO, nothing is more important than sorting out the brakes. It will give you confidence to charge the brake zones which translates to quicker lap times. Got the spare wheels tossed on to roll it out for a bath since it was still wearing the grime from the Charlotte race. Its getting moved to the paint booth this week for a livery update and contingency decals in time for CMP.

  2. Whelp, figured out what the delay might be with the pump. What idiot in shipping does this?!?

  3. What @wvumtnbkr said. The corner worker still takes precedence. I believe towards the end of page 5 in this thread, there is a picture of our Sign Boards that we will be releasing soon to tracks and sanctioning bodies. Our in-car Flagtronics devices have brought up the communication speed so fast between the race director and the driver (faster than some of the corner workers react to the radio communications now). The hope is to now bring that speed to the corner workers now too and have the corner stations and in-car units change at the same time.

  4. A benefit of being around loud cars every weekend, working on F111's and F15s, and being in a house with 4 really loud grand kids is that you are numb to the noises now.

  5. Troy turned me on to Seals-All. Works on fuel systems and fixed this exact issue on our car before a race a few years back (ours was a tweaked FP flange keeping the o-ring from sealing. Always keep a tube on hand now.

  7. Unfortunately, they will not be compatible. The differences in communications equipment, hardware, and software will likely not allow this. It is unfortunate that the two companies had the same good idea come to a fully developed product at roughly the same time, putting racers, sanctioning bodies, and tracks in an awkward situation, but at the end of the day both companies are trying to improve the safety of the sport we love and have gone about the solution in slightly varying ways.

  8. The difference between our stock T/A brakes (not too shabby) to the C5/6's was amazing. We can carry all kinds of speed down the straight and out brake a lot of cars. Well worth the $$$

  9. You need the recommendation for a starting point, from there it gets tweaked with their help, if their help isn’t helping you start making your own decisions. If it gets tough you need heat paint to find out your temperatures, but honestly, it’s not that hard to figure out if stuff is overheating.

  10. I don't think carbotech was the only supplier that gave non perfect advice.... Find out what your fellow races are running and go with their first hand experience... that's my suggestion. Also, if you have been using something and it works well, then suddenly does not, look at your system. There is probably something wrong. I changed every single part in my system twice and was sure it was a pad issue. It needed up being the 1 part I didn't change.... the brake booster! (Ya know, because there is no way a booster fails and gives you MORE boost.... except that, yep there is a failure mode that does exactly that). If you have a unicorn or orphan build, then, take the pad companies suggestions, but realize this is just a starting point.

  11. No!!!! Never use RTV in a fuel system, I did that thinking that it would dry around the fuel sending unit o-ring, ( just to make sure it wouldn't leak) it was a month later before I added gas to the tank, the RTV oozes out once gas contacts it and fell into the tank an was sucked up on the screen in the fuel pump, one good test session followed by 3 bad ones! Then home and saw the RTV in the fuel pump inlet!

  13. we run a pan from speedway, not cheap but we run a 305 pretty hard no issues. We use the extra long oil filter too. It helps to clean up all of your oil passages. They aren't very smooth from the factory.

  14. So far so good on ours. It’s got about 1000 miles on it and is switched on and off by the ECU at around 220 degrees. It pulls 75w90 trans oil from the drain plug and pushes it through an 8"x10" cooler on the output with about 12" of head rise before it's returned back into the case. As others have stated, it’s noisy but it gets the job done. They all seem to come from the same overseas factory, but I went with the SeaFlo variant because it seemed to carry some sort of name-brand recognition. YMMV.

  15. You might want to look at Acusump. We have both a Pan and acusump on our C4... I understand about points, we are over points and take laps but even with 6 laps down at Daytona we finished in the top 10 overall.

  16. With the current rules I would look into something like a honda D15 (60 ish points to swap) as the motor swap. You could then swap on some d16 parts for points or aftermarket. I think 110-120 wheel hp would make that car fly. This is assuming the D15 is reliable, something you want to actually work on etc. Common practice, you will find it is more point conscious to swap in a lower HP engine that you can fix with "fixed vpi" items after that swap (like cams) rather than swapping in a motor that uses all of your points and has to remain stock. Either way this is going to be an uphill battle with your swap weight of 1200 lbs. The national champion, a CRX, was given a swap weight of twice that (2318). If you are serious about the build you may want to lobby for a higher swap weight, especially if you think the finished car weight has no possibility of being close to 1200 lbs.

  18. When you build something that is maybe pushing boundaries, a good idea is to keep tech informed through all of the steps. At least explain to tech, before you build, what your intentions are. Pictures and examples go a long way. Good luck!

  19. I love everyone's rants as they are based in experiences good and bad. Best way to learn from other racers. I definitely agree with you on not reinventing the wheel that works. Racing is a drain on time and especially money so anything that can save either is key. I don't mind spending money if it saves my time and vice versa but time is worth alot these days.

  21. Sorry, hard to move on without a minor rant. They {carbotech} NOW have a understanding of chump/champ, I tend to believe, from some of our dealings. Gave them all the specs 11 years ago, 10 years ago, 9 & 8 yrs ago, with horrible results , everyone @ each company was super nice, but had no clue what our needs were vs what product they were suggesting (and we were buying) Specifically, after 2 years of going round and round, Carbotech was sure our setup was somehow to blame for miserable results w/their personally recommended pads, "no way we are exceeding the specs on" [this or that] "pad with our tires" . I thought to myself, who was I to question the manufactures/engineers/experts on their recommendations? I dared not, but after failing for so long even with minor tweaks to their suggestions, I had to insist/promise not call them back for failing w/xp24s (my idea) that would "be the most expensive paperweight ever purchased" as there was no way we would ever be able to maintain proper operating temp. 8 years later they still get our $$ for xp24, now in custom thickness w/brass rivets , to make use of every bit of free space available. Are there more ways to skin a cat then we have figured out? Absolutely, perhaps on a new car that needs new answers, this one car is set and forget, it works & lasts as it is now. For the curious: z33 front calipers/rotors + z32 rear calipers/rotors.

  22. I also used a dirt bike gear bag from AXO I Believe. Holds everything and then some. Stilo helmet bag, suit, cool shirt, gloves, shoes, drink bottle with plenty of room to spare. Plus I think I only paid $35 and its served me for 2+ years at this point. I love it, and its my team colors to boot.

  23. Oh, was installing the new racecapture pro mk3.... had to take the intake manifold off.... Forgot that the water temp sensor is in the lower intake manifold. Crap. Had to take lots of other stuff off to make it happen AS WELL AS the fuel line, vacuum lines, throttle cable, etc.... oh well. It's done now and I have reliable sensors in place. Tomorrow, I finish wiring and mounting the racecapture and the tablet to have as a dash.

  25. Well, you can quit debating that. 4.5.5. Engine being swapped in must come from another vehicle in the VPI table, unless the Foreign Market Engine exception is used.

  27. Yea, I waited for the flag to be pulled. This is the in car of it. You can hear my radio when he says it's going to go green, then you see flagtronics turn green. It's hard to see the flagger from the video until it gets closer, but then you can see it was still double yellow. Also, I need to have it in 2nd for restarts...3rd is no good. Must remember that next time.

  32. I had a similar incident with a fellow last year where it looked like there was plenty of room until he started closing down on me. I thought it was best to back out of the pass, but couldn't fully get out and I pit-manuvered him (and myself) off the track. I got to talk to the other driver the next morning. I asked him two questions. First: "you saw me coming and knew I was back there before the brake zone didn't you?" The answer was Yes. Second question was: "before you turned in, did you look to see where I was?" His answer was "no". That was pretty much the end of the conversation. We served a penalty for the incident and my car took another trip to the frame shop a few weeks later. This incident looks much the same, but I am judging by the footage of the car behind where the a-pillar gets in the way. But if you are involved in an incident that you could have avoided had you looked before turning in, then you have some skin in it. Sorry to offend, but there is some give and take in this. No one car has unlimited right of way.

  33. We also had one in our blue Volvo and thought it worked well. Only once did I have a contradiction, but that was the fault of the turn 10 flagger holding out the double yellow while my crew chief and flagtronics were green. We shared a garage with the Flagtronics team and they were telling us some of the other potential features. I hope they can follow through on them, because if they do, the $150 price point will be "ChumpChange" for the things it can do.
