  1. You would think that a person who travels the world dealing with manufacturing machinery would understand how to use feeters and bars. and I KNOW Brad likes bars. 😉
  2. didn't use the canopies this weekend, but there's only about 20 ft of metal roofing on top of the garages.. it was brutal hot over the weekend and more shade would be appreciated. I know they're working on it, but daaaaaamn that sucked having no shade up there!
  3. too many wants. not enough money or space. GLWS.
  4. Alamo Autosport is in Ft Worth. Bryce has been reputable in the Honda game for 20+ years.
  5. Just a question-- are you planning to race the car in any major groups? (SCCA, NASA, etc)? going behind the front axle centerline is a no-go for many classes because it then becomes underbody aero, not just a splitter and airdam. If you're not planning to build to a rulebook, then carry on and enjoy the fun. 🙂
  6. The "timing tower" is currently being repaired too, but it will not be rebuilt as it was previously-- it's going to be converted to single story structure with an observation deck on top. For those that don't know the whole history, there were 1 or 2 of the canopies that were dead from just old age. one on the far end got hit by an enclosed trailer (multiple times) and damaged it. ....Then a tornado hit the track at an SCCA race a couple years ago (I can't remember if it was memorial day or labor day race weekend). It ripped the roof off the timing building and dumped it on the track in Diamonds Edge.. on its way there, a section of roof landed on top of the garages and punched a hole in the roof. the canopies were also damaged pretty bad in the process- not sure if that was due to being struck by the roofing material, or whether the tornado just ripped it all apart. The entire back straight was covered in sheet metal, nails, and other construction debris. corner workers and track staff spent a couple hours walking the track picking up nails and wood and whatnot. The All of the timing equipment and CCTV system was damaged since the equipment racks were in the old timing tower and got wet. the track was out of power due to a power line down at the entry, so one of the racers loaned a generator to race control for the day. they were able to set up a temporary timing system and whatnot, and race control moved into the "fitness center" and spent the day in there with no A/C. (it was well over 100F inside there since there is only the single door and air couldn't circulate!) Amazingly, the only private property damage I've heard of was a couple EZ-ups that were left out, one struck a car and caused a flat, and something hit an RV punching a hole in it. So that's how the track got to the condition it was in. Why it took 2 years to repair, I do not know.

    Agree with that sentiment. I purchase quality safety equipment, but I can get a good quality glove for sub $100... regarding longevity, I think it's a crap shoot honestly. I bought one pair of Alpinestars Tech-1somethingsomething glove and put a hole in the thumb webbing after about 6 races. I used some Nomex thread to sew it up and ran them for a couple more seasons before another hole developed. I then picked up a newer version of same glove on year-end sale at SafeRacer and have done multiple seasons and they still look new. I can't remember the brand, but I bought a set of $250 shoes (on sale) and the soles fell off within a season, but the $89 shoes from same manufacturer have lasted years with no unexpected wear.
  8. Yep. typical fill on a bottle is 2500-3000PSI. so that's a LOT of cubic feet of gas at 14.5psi..
  9. Those guys are considered more repeatable and accurate than the clicky type, because the flex rate of the steel is a constant (within the temp range humans can survivably work in anyway). so if they drift from zero, you just bend it back until it re-zeros and you move on. easy to 'calibrate' and the only drift is the zero point.
  10. ahh ok. yeah that makes sense. I was only partially paying attention since I was posting from work and pretending to actually be working. 😉
  11. can you post a link/image to the e throttle wiring diagram(s)? maybe the interwebs can assist with info.. if I had to make an ASSumption, the ethrottle spits out a signal voltage to indicate throttle position while it's operating.. that voltage needs to be stabilized somehow and read by the ECU. i.e. pull-up/ down resistors. depending on the voltage and current, that could be requiring a fair amount of juice.. just a quick calc says 25-35mA (I used 30mA) / 12V = 400ohms. *typical* pull up/down resistors are in the 300-1k ohm range, so that's not far out of question. However, 30mA load on a standard car battery (say 65Amp-hours) should last well over a month before discharging-- maths says 2166hrs = 90 days to full discharge. So I suspect there's likely something else happening somewhere that you just haven't found quite yet. also, how old is the battery? any chance it's just getting old? batteries typically die in the hottest part of summer and the coldest part of winter. they'll be fine one week and then *bam* crap battery that won't hold charge a week later.
  12. Glad to hear all your hard work has come with good results! And no lawnmower blades of death!
  13. It's not until November, but CVAR has a race scheduled Nov 1-3 weekend, and SCCA has Nov 8-10 on the calendar. I don't know why I thought they were earlier as I've been staring at this calendar for months trying to figure out which events to skip since the calendar is full every weekend but one from now until Nov 17... (sometimes 3 events on same day in different states!)
  14. a refill on a 125cuft bottle is under $20-- at least last time I had my C25 welding tank filled up, and nitrogen is cheaper than that. a friend of mine has a large 300cuft bottle in his trailer and he doesn't even bother with an air compressor for his impact wrench.. he just plugs his hose into the tank and uses it for his impact wrench, "air" source, etc.. said it's been in the trailer for years and he hasn't had to refill it yet. I'm thinking of the same philosophy, but with a 150/200cu ft bottle to reduce weight in the trailer...
  15. Pro racing is such a different environment than club level on those regards...
  16. I don't blame you. lots of drama out there. but I like watching dumpster fires. FB can be a useful tool.. but it can also be a timesuck that you'll never recover from..
  17. there's a complete diff listed on houston Miata Club FB group page right now.. see if this link works: https://www.facebook.com/groups/HoustonMiataClub/permalink/10156572694647215/?sale_post_id=10156572694647215 might be good to have spare parts. :)
  18. Yep.. in my case, I'm going for overall shortest time to hit the checkered flag 15-20 laps later. so if that means peddling it for a couple laps until temps and pressures are right, then hammering it for 10 laps and holding on to the finish, then I do so. Ideally, I'd have a consistent tire from green to checker, but that doesn't happen on slicks. I had much better consistency on DOT-Rs in a lower power car with (minor) aero where I couldn't abuse the tires quite so much under corner exit. another thing that would help all of us on that aspect is going to nitrogen purge/fill in our tires. houston (TX in general) air is stupidly humid and causes lots of pressure rise as the tires get hot. I also see easily 10+PSI change in a session, but I'm using compressed air from my tiny compressor at the track with no filter or dryer. http://www.longacreracing.com/technical-articles.aspx?item=70794&article=Tire Pressures - Cold to Hot I've had plans to install a nitrogen bottle in the trailer for years, but I've just been too lazy to get it done. it's on the list, but stays near the bottom as a nice-to-have.
  19. Good stuff. With Katech doing work on the car, I had assumed you were tuning a recently built/replaced engine already so I was hoping he didn't hurt a 2-race engine!
  20. Drew Kim had a Boxter and now has a 911 GT3 and a Cayman (and an F250). the Cayman is his 'daily' when he's not in the truck and he absolutely loves it. the GT3 is a track toy and not really suitable for daily driving. I can't imagine the maintenance costs in driving a GT3 around.. just not what it was intended for.. the way I see it, your 911 "friends" are looking down their noses at you because anything NOT a 911 is garbage to them. The Boxter is a hairdresser's car, and a Cayman is a poor man's wannabe 911. The rest of the model lines don't count since they're not a 2 door sports coupe. congrats on the purchase! black cars sure are pretty, but I don't wash mine enough and it would always look like crap!! "hides dirt silver" is my color of choice! :)
