    The 'oops' videos are usually the most interesting :confused: The quick runs usually look the least spectacular on video. I'm hoping to be a bit more 'together' when we run the next trip..

    ----

    So, about that axle leaking stuff.. I think we found the problem!

    [​IMG]

    I noticed a bit of a leak before the Camaro Club event (mentioned in my post on the 7th). Before what I was planning to be my last run anyway, I noticed the barrel of the wheel was shiny. Climbed under and noticed a drip of oil on the bottom of the rotor, and a pretty moist housing end.

    The last time we rode this merry-go-round, it had just shucked the inner seal piece on the bearing. We're never ones to let up, though, and I think we got all of it this time. New Moser axles with tapered rollers came in yesterday, and dad got them swapped out last night.

    We'll put them to the test Sunday, as we're heading right back to Lone Star Park, where I assume the last one got broken.

    I've also noticed some pretty significant brake pad kickback the last few trips out, I'm hoping this will help in that area, too. Nothing like having a manual pedal that requires a ton of pressure, but not being sure if the free travel is going to be nothing or an inch or two as you're approaching a turn..

    Thanks to SSLance, who owns a wicked Monte Carlo SS on Lateral-G for some tips that greatly simplified the process of chasing down the problem.

    As the end of summer approaches, I've started a winter 'to-do' list. This year was always a "work on me, get on the level of the car" campaign in my mind, and I'd like to travel a bit and hit it hard with some improvements next year. Right now it includes:

    Needs:
    - Adapters to use a standard coilover spring up front so we can bump the rates; possible bump in rear rate as well, need to put pen to paper to see
    - Install the new brake and clutch master cylinders we already received from Wilwood. This includes a size change for the fronts to get a little more travel and lighter pressure requirement at the pedal, and hopefully a much better feel overall
    - Bigger, dual-pass radiator to help with summertime and road course running; ducting to the grill openings and blockoffs around the rad to clean up airflow up there
    - Airbox that fits to the cowl to keep the heat off the carburetor

    Wants:
    - Stiffer front swaybar (likely a splined Speedway unit or something similar of our own design)
    - Adjustability for the rear bar - right now it's fixed and way too stiff for everything else in our current combo. Either way, being able to tune it is a must in my book
    - Fuel injection (big ? at this point)
    - Air dam/splitter
    - Stock look fiberglass dash and some more interior pieces including an insulated headliner to (a) chase a few more points at Optima events and (b) not roast quite so bad in the summer

    And I'm sure there will be more..

    What is your master cyl & caliper combo now? I'm currently running a 1" master and thinking about a switch to 7/8 with my C6 setup.

    We were running 1" both front and rear, with Wilwood 6-pistons on the front and GM metric front calipers on the rear. The new setup will be 3/4" for the front, 7/8" for the rear.

    SCCA Event #6

    Sunday was the first trip out with the new axles and bearings, and I was looking forward to getting back in the car with my head screwed on straight after the debacle that was the last trip.

    [​IMG]

    The course was fairly technical this time as opposed to the wide open flowing elements we typically have at LSP, which was actually a nice change. Got things started off on a weird note, as it was pointed in tech out that the Z had lost a screw in the undertray on the trip over, and it was nearly dragging the ground.

    [​IMG]
    Bring the racecar to the track, work on the daily driver..as you do.

    A few zipties got everything back in order, and we set back to the regular morning routine.

    I noticed the night before that the CP Camaro of Jeff Stroh and Todd Farris (of http://www.oversteergarage.com) was entered, and we ended up parked right next to them. Regular routine: derailed.

    [​IMG]

    We talked for a bit, they had a look at our car, and soon it was off for drivers meeting and first heat. Things worked out perfectly, as I was off this heat and they were running, so I begged a couple rides, tried to help where I could (provided a little muscle helping to push it), and mostly tried to stay out of the way while they did their thing.

    [​IMG]

    What. A. Ride. They had to fight a pretty dirty course going out first, and a setup that was geared for the grippy concrete of Lincoln rather than the course asphalt, and it was still a MONSTER. Hopefully we cross paths again, it's a joy to watch, listen to, and ride in.

    Back to the normal program, running last heat gives you plenty of time to roam around, catch rides with friends, stare at the sky and ponder life, etc. The temps were moderate, in the mid-90s, but the Houston-esque humidity made it just about as tough as the last few 100+ degree events.

    88 mph! 88 miillleesss per hoouurr!

    I took the 3rd heat to make a sandwich and cool off in the truck before heading out in an effort to not repeat the sins of the Camaro club event. Grabbed rides with my dad and Jon in his CAM-C Mustang to re-remember the course, and it was time to saddle up.

    [​IMG]
    After my morning ride-alongs, it's HILARIOUS that we call this the 'racecar'!

    Things went much better this time, with a reasonable calm, controlled 52.8 right off the bat. Right around what I was expecting, but with a couple cones. A 52.211 followed, which was good for the top overall CAM time and would be my best of the day thanks to a rash of cones that wiped out a 51.678 on the fourth run - class results.

    Speaking of that fourth run, about a 1/3rd of the way into that one I noticed a fairly loud whine from somewhere in the driveline after letting off the throttle into a turn. The first section out of the start felt pretty messy, and the noise sealed the deal on a slow 52.5. Looking back at it on the logger, it was actually quicker until letting it push wide about 2/3rds of the way through.

    The second, fully charged GoPro battery eluded both of us, so we didn't get video of my session. I was able to use the tablet between runs to compare lines, which proved to be pretty helpful.

    [​IMG] [​IMG] [​IMG]
    Runs 2 and 4 charted - click to enlarge

    We pretty much always say distance is king, and that was the case. This corner, the tightest on the course, seemed like a good opportunity to drive in deep and go for a late apex, getting back to the throttle quicker for the next fairly straight section.

    [​IMG]

    In the session before, I actually discussed this with Jon as he 'pinched' it, and we both agreed that the late apex option should be better. It even felt better in the car..but the numbers don't lie. I entered the section with a .162 lead, and left it basically dead even. The exit speed was nearly 2 mph higher, but this didn't translate into any gain through the next section, either.

    Distance. Is. King. Good stuff, and I can't recommend SoloStorm from Petrel Data Systems enough.

    We haven't gotten to investigate the noise yet (hopefully it's just in my head?), but it was a great day overall.

    On to the next one!

    One more bit of Optima Wrap-up

    [​IMG]
    'As seen on TV'

    Friday night was about as much fun as I've had sitting in front of the TV in forever. It was Optima Texas night on MAVTV, and it didn't disappoint.

    Bangshift Chad, Kevin Mooney, and their entire team work their butts off at these events, and we spent a good chunk of time with cameras strapped on the car throughout the weekend. The show featured great coverage of many of our local guys and shops that contribute to the scene here, and it was great going "Hey, there's X" as they each got their respective segments.

    Fairly early on, during a short montage of newcomers to the event, BAM there we are! Complete with a buzz up past 7,000 audible in the background. Ok, I'm good now, anything else from here is gravy :cool:

    Backstory: Drag Week 09

    A little bit of background with us on doing these events with media coverage - when we did Drag Week, we had two main goals, and a third slightly less important goal. The two main ones were to (1) finish the week, and (2) get a 10 second timeslip. Done, and done. The third was to appear in Hot Rod Magazine, even if it was just in the background of a picture. We 'Long Hauled' two Power Tours in 03 and 04 and never made it in, so we had to have better odds with a lower car count, right?

    A few months after the event, the mag came in the mail and the event coverage consisted of around 30 cars from the week, and that was it. Long story short, we were a little bummed, but we knew running 11s in a car like ours it was a long shot anyway.

    Back to Optima

    Hey, I recognize those gloves..and HANS..and car..

    My big long wrapup posts intentionally overlooked a fairly big part of the weekend for us: shooting a segment with Mike from Wilwood. We felt pretty sure it would make the show, but didn't want to look like jackasses if we talked it up and it ended up on the cutting room floor. About 45 minutes into the show, I saw the image above coming out of the break and let out an "OH S..."

    [​IMG]
    'I don't know what to do with my hands..I feel like I'm in a spaceship'

    Early in the day Sunday, we found ourselves in the garage during a fairly quiet time, and caught Chad walking through. After some pleasantries, I told him we had talked to him on Drag Week in 09, and he lit up and remembered the car. We bench raced for a bit, and he brought up the idea of shooting a feature for Wilwood highlighting the multi-purpose nature of the car and the different braking demands of an event like this vs the drag strip.

    A bit later, Mike from Wilwood came back over and went through the plan with us, which was to shoot the car going into the braking zone at turn 1 from both on-board and outside, then shoot a segment in the garage discussing the braking performance and potential upgrades after coming in.

    [​IMG]
    First wheelstand on an Optima show?

    I may be biased, but I felt like it turned out great. So many shows put sponsor copy in the host's hands and just shoehorn these types of things in there, but this felt much more natural. In our case, we went with Wilwood from the start and recommend them to our customers, so there wasn't a need for a prompt for me to speak well of them.

    The cherry on top of the whole deal was wrapping up the segment showing Smitty going back out for an extra session in the 48 Hour Vette to improve his road course time in response to our best lap. We had no idea we were anywhere close to him until after things wrapped - I was just having a blast flogging the car on the road course for the first time.

    All in all, a very cool way to wrap up one of the most fun events we've ever done and set the hook hard for us to get back at it next year. Huge, huge thanks again to Chad and Mike - my dad and I were still giggling about it hanging out at the lake this weekend.

    And I'll say it one more time - if you have the capability at all, get your car out to one of these events!

    Bring on 2016!

    Little update time - we got back on the road course!

    [​IMG]

    ..they just stuck a bunch of cones on it first :confused:

    Every year Texas SCCA does one autocross event on the infield road course. It's a lot more open than their typical courses, and stretched 2nd gear pretty good.

    Your CAM-T class for the day​

    Looking at the video, I'm thinking I could have shifted 3rd and probably gained a little time, but the downshift into that hard braking zone would have made things interesting. As it was, I 'backed into' that section a few times, with the rear getting very antsy under braking.

    [YOUTUBE]OhngbSSL4zA[/YOUTUBE]​

    Didn't get video of my fastest two runs, but this one was pretty close. I was able to clean up the last group of offsets a decent amount to find some time.

    We've probably got a few events left this year, then we'll start evaluating the to-do list and the calendar (this time of year always gets crazy), and getting to work.

    ALSO..I started a new job a few weeks ago, and I'm loving it already. Exhibit A: if you're going to SEMA, come see me at the Traxxas booth!

    End of season update! Last event of the year for the car was last weekend. Tricky course, I was a bit tired, driver excuse bingo.

    Still a fun day, but I never got a handle on the course. At all. Even on my last run, there were 4 or 5 spots I just couldn't get the car feeling right on.

    My trusty crew chief was also on hand wielding the big camera. Can't wait to get started on the suspension work and tame this thing..
