carterb Posted November 9, 2018 Report Share Posted November 9, 2018 (edited) Saturday morning - back at the track bright and early. We noticed they had a nice bottle of Coca-Cola prepared for Jeff. This is going to be so awesome! We looked over the car again, making sure the lug nuts are tight, making sure the fuel is topped off, oil, water, etc etc etc. We learned at the Ridge that we don't all need to qualify so just one of us went out. I don't remember if it was Jeff or Sam this time but I go to start the race. Let me assure you it is pretty exciting driving a race car on a race track. It is even more exciting taking the warm up laps with a bunch of cars around you. And it is even more exciting that that when the green flag drops and everyone stomps on the gas - especially when you have never driven the track at speed! in this series there is no formal starting grid. You start where you take the track. Want pole position? No problem, line up first! We are not here to win, we are hear to learn. So I started well at the back - hoping to have a few laps where I could focus on what's out my windshield instead of what's in the rear view mirror. Each lap you get more familiar with the track and the limits of the car and lap time starts dropping pretty quick. Jeff and Sam were watching the app and at first - they classify the cars based on the lap times they are turning. Then the group A drivers start passing you and a little later you start passing other group C drivers and sometimes group B drivers. Jeff and Sam were watching the standings and we started in group C, then got bumped to group B. Well that's pretty cool! Then, as the lap times fell, we were bumped to group A! Uh-oh! That was early on though and once everything on the track settled into a rhythm we were back in C where we likely belong. I tell you what though, I would say that we were equivalent or faster than about half the cars out there! Lots of people to race with. It was so awesome! Everything ran really well except... The main straight is a full speed affair for a LONG time. There is a left hand kink about half way down that can take 3 cars wide at full speed. Then soon after you get to turn 1. We were warned on many occasions that there is an undulation at turn one and you must take it with the throttle pegged. If you let up it will unsettle your car and you will end up crashed or dead. No kidding! Well, here I am, barrelling down the straight, coming up to turn 1 and the car starts cutting out!!!! Are you serious?! I'm going to die?! Well the car coasts into the corner as I'm keeping it floored and after about 5 seconds? The throttle picks back up just in time to hit the brakes for turn 2. This happens lap after lap. I'm no longer scared of taking turn 1 off throttle but I'm sure tired of doing it! Here you go racing neck and neck down the straight with another guy and then you "lift" 500ft before the corner starts and they go flying by. *sigh* It's going to be a long day. Before you know it my hour is up and I come into the pits to hand the car over. This is an exciting time where we refuel and as the outgoing driver - still full of adrenaline - try to let the incoming driver - just getting hit with adrenaline - know what they can expect - like the car cutting out at turn 1. Then we check the belts and mirrors, etc and send them onto the track. It is a real sense of accomplishment taking this car that the three of us built together and racing it door to door with 50 or so other racecars. This is awesome! My driving wasn't over yet though - I had to go to town and fill all the gas cans. Turns out it takes a LOT of hundred dollar bills to go racing... Meanwhile, back at the track: Edited March 2, 2019 by carterb 4 Quote Link to comment

carterb Posted March 1, 2019 Report Share Posted March 1, 2019 (edited) Race prep has started for 2019! I need to finish the report from last year! Seems like ages ago not so I will have to let the pictures tell most of the story... Sam or Jeff came in from their first stint and mentioned the car felt weird - like something was loose. Turned out to be the adjustable rear trailing arms coming out of adjustment. Back to racing... Jaybo Racing Fan Club!

carterb Posted March 2, 2019 Report Share Posted March 2, 2019 Well into the afternoon now! So cool to still be racing after our Shelton experience. Time for some nourishment! Final lap! Last trip down the straight. Passing one more car! Checkered flag!!!! Sailing off into the sunset? Coming into the pits And not on the back of a flatbed wrecker!!!! Yahoo! 4 Quote Link to comment
carterb Posted March 2, 2019 Report Share Posted March 2, 2019 Jeff getting out of the car Team Jaybo Racing Did we pick up a rat while driving? Nope, those aren't droppings, those are what's left of our tires! Hmmm, race is 1/2 way done (Day 1 complete) but the tires are ??? More fans! 5 Quote Link to comment
carterb Posted March 2, 2019 Report Share Posted March 2, 2019 Everyone went home for some needed rest and it was back at it bright and early the next morning. As we were checking out the car in the morning, we found a little issue: One of he half-shaft U-joints was toast! Too bad we didn't look over the car the previous evening because we had no spare with us. Fortunately, Jeff's wife was able to locate one in the garage and started heading South. We wouldn't be making the 9am rolling start but that was okay because it didn't look like we had a full day's tires anyway. Replacement part in-hand and Sam is completing the swap. Jeff say's "Watching's helping". Meanwhile, the cars are lining up to go out We're actually not far behind. Delivery drivers And back to racing! http://datsun510.com/uploads/monthly_2018_06/IMG_8089.MOV.a8d382cc9fa724a935dcd4ce5afcbdd7.MOV http://datsun510.com/uploads/monthly_2018_06/IMG_8090.MOV.866c25cea46447f87d73ed900851065b.MOV http://datsun510.com/uploads/monthly_2018_06/IMG_8091.MOV.066de72e7e0cb4f33f3548fafdd90d6c.MOV http://datsun510.com/uploads/monthly_2018_06/IMG_8092.MOV.633bd70535d9f644aba95656223e6233.MOV Soon after we started, I was black flagged for our "Flappy hood." One of the corner workers thought it was loose. Race control informed them after I came in for inspection that our car is just "old". : ( Holden sees something cool! It was about to get really exciting! Somewhere near the end of my stint, I was following the turbocharged MR2 on the back stretch, through 5a and 5b and got a much better exit out of turn 6. It was a drag race up the hill and I went to the left, began to pass, and was a full fender ahead of him on the inside of turn 7 when he went for the apex like I wasn't even there. **BAM** Crap! I was happy to have stayed on the track because just inside 7 is a really nasty ditch that looks like it could rip the front corner off your car if you hit it. I lifted, went to the outside of 8, and headed for race control in the pits. Luckdog rules say that any contact means both drivers come to the pits and both drivers are penalized (time) unless one driver owns up to being fully responsible. The MR2 pulled in behind me. I explained my case and the steward went to talk to the other driver. He came back to me and said "the other driver said it was his fault" (um - yeah) and sent me on my way. I did a 180 and headed to our pit box so we could check out the car for damage. Fortunately, it appeared to be superficial and my fireproof underwear were unsoiled so that was all good. Pictures don't do it any justice but we got some nice rub marks and the rocker was ripped open below the door. The brakes were in need of adjustment - again and I only have a couple laps left in my stint so I'm pretty sure I gave the car up at this point. Oh yeah, the brakes. I'm pretty sure it started Saturday but the rear brakes started to go on us. They would not quite last for an hour before needing adjustment. So half way through your stint the brakes started to require a double pump to get a pedal. Not exactly confidence inspiring, but we never lost them completely, and did get really good at adjusting them quickly between drivers as the weekend went on. Turns out Sam likes brakes. : ) Video of one of us on Sunday - still racing! http://datsun510.com/uploads/monthly_2018_06/5b18b10f9fac4_06032018swampthing(1).MOV.4134414de7edb5a1dc503404bf9ea929.MOV Sam also likes adjusting brakes! 3 Quote Link to comment
carterb Posted March 2, 2019 Report Share Posted March 2, 2019 Jeff was next in the car. Sam and I are on fueling duty. More checks/adjustments and possibly a tire rotation? Jeff's Sunday drive ended a bit early - again. He say's Sam always hands him a broken car. : ) Maybe we'll have to change the driving order this year. But if I remember correctly Jeff is the only one to blow up a race motor so... Anyway, Jeff came in after a while complaining of a really bad "thunking" noise. We raised up the car to see what we could see. Suspension looked tight. U-joints all looked good. I don't remember if we found anything to adjust, but somehow we determined that I should give it a go. The road leading onto the track is pretty rough so it was difficult to say for sure but as soon as I got past the starter tower and entered the track heading to turn 2, it was obvious something was really wrong. It sounded like someone was hitting the car with a mallet every wheel revolution or so. I kept it in 2nd or maybe slow 3rd all the way around the track and came back into the pits. I was in full agreement with Jeff that something was very wrong and we determined it was terminal. It was about to start raining too and our tires were basically slicks so we figured that this setback may have saved us more damage later. So we hung it up half way through day 2. A significant improvement on our first race for sure and we have learned allot about what it might take to finish a full weekend of endurance racing and are already excited for 2019! We talked about doing another race in 2018 in Oregon but the fact was - we were really pretty tired of working on the racecar this year. We were all ready for a break! We'll be back. 4 Quote Link to comment

Maschinenbau Posted March 6, 2019 Report Share Posted March 6, 2019 Just finally caught all the way up on this thread. That racing league looks like a blast! I always wished there was something budget-friendly between 24 hrs of Lemons and typical track days, and they seem to have filled that niche. Sorry about the L20 failure, but thank you for all the carnage pics. Looks to me like a normal case of rod bearing oil starvation. All it takes is a little bit, especially at high RPM, and that bearing gets hot enough to seize the rod on the crank and it goes full weed-wacker. Even with a good baffled pan like the one yall made, if the oil can't make its way back down, no bueno. That SR should give you plenty of trouble-free racing miles. Good luck out there and keep it coming. 3 Quote Link to comment
volkswagner Posted March 11, 2019 Report Share Posted March 11, 2019 Looks like you got everything Carter. On to the 2019 season! Swamp thing was stored at Jeff's all year. We parked it after the last race and didn't touch it except for an occasional startup by Jeff to keep it lubricated. With 8 weeks until race day, We finally decided it was time to start getting the car prepped for the season. After all, we still don't know what that clunk was! Luckily Swamp thing started up, seemingly no worse for wear than when parked. 1 Quote Link to comment
volkswagner Posted March 11, 2019 Report Share Posted March 11, 2019 First order of business, whats the Clunk! The prime suspect was the differential since the noise was speed dependent and very loud. Out it came. Once on the bench it was obvious... that this was not going to be as easy to figure out as we had hoped. No matter how hard he looked, Jeff just couldn't see anything wrong with the diff. He called in a keener set of eyes. Still, there was no signs of damage. No witness marks on the teeth, no metal in the oil, no disruptions felt when rotating the gears. As far as we could tell. The diff was tip top. On to lesser suspects. We started spinning everything from the transmission back feeling for play or resistance. Nothing substantial. We got to the rear wheel bearings and the passengers side assembly had distinctly more friction the the drivers. "Hey did we ever change the rear wheel bearings during the rebuild?" "No" Lets remember where this car came from, 🤔 😬 A little help with the cutting wheel to separate the races. Sure looks like something spent some time getting to know each ball a little to intimately. Is this our culprit, or is this just a bad bearing that was a whole separate problem? We honestly aren't sure ourselves. Only way to know is reassemble and test drive. It's a little easier to believe when you consider that the rear crossmemeber is hard mounted and there is no interior what so ever to stop the direct transmission of noise from hub to cockpit. Well, since the rear end is disassembled. No better time than now to sort out that failing rear brake situation. 2 Quote Link to comment

volkswagner Posted March 16, 2019 Report Share Posted March 16, 2019 6 weeks until race day! Not as much to do as last year but still a good size list. Only a few things would keep us from racing so we're feeling comfortable. As long as the clunk stays away... Last year we dropped the SR in and it fired up so we rolled with it. We decided to take a look at the basic tune up parts we ignored before. Plugs, don't look too terrible but we decided to swap out to some new coppers for better robustness. The plug pockets being filled up with oil led us to yank the VC cover and find a worn center seal. Changed the fuel filter. How about the cap an rotor? Whoops! We might have been leaving a few HP on the table last year. Got a little further with the rear brakes. A bit of test fitting showed where the deign needed tweaks. Now to cut some aluminum. The B&M short shifter we installed last year was proving to be more hassle than it was worth. It just never felt right and was causing mis-shifts which doesn't help our gearbox longevity any. Time to put the stock part back in. Once it was out, the poor shifting made a bit more sense. (Those are supposed to be straight.) This jogged Jeff's memory, he had gotten the part from a guy who had to "hold" his bad gearbox in 5th. I must have missed the damage when installing it in our rush last year. Two birds with one stone, we were also leaking transmission fluid last year from what we thought was the output shaft seal. Turns out it was a failed seal on the shifter. A little honda bond to sort that out. You'll recall we had issues with our hood flapping as we went down the track last year. The old race hood had it's support structure removed, coupled with the corroded state of it and our missing front valence sending 120mph winds directly into the bay meant the hood had cycled itself to failure. Luckily Jeff had a color matched hood on hand. with good support structure. He was even able to find some hinges to make opening the hood a one man job instead of the 2 man lift needed for the 4 pin hood we had. Much better! 3 Quote Link to comment
carterb Posted March 17, 2019 Report Share Posted March 17, 2019 (edited) I'll try to catch up. Jeff and Sam under the car. (I think we spend more time UNDER the car than IN the car) Investigating the bearing noise after checking out the rear end requires grinding off the "crimp" on the crimp nuts After we discovered the bad bearings - www.rockauto.com started drip feeding me replacements: Multiple shipments at least came with multiple magnets! We are pretty sure the old control arms were bent - either on purpose or from abuse - during the car's previous circle track days. I found a set of replacement arms in my parts department. Sam and Jeff. So this is what the top side of the car looks like! Even though the trailing arms were "new" we weren't going to take chances this time so out came the old bearings: And in goes the new: The hardest part is getting the old bearings off the stub shafts Once back together, we could test fit the new rear brakes Side note - Jeff needs one of these. Don't let me forget! The Monster Truck (our tow vehicle) needs new brakes too. Although I rebuilt the rears last year the braking was still quite weak. I have new pads/rotors/calipers/hoses etc ready to go and am waiting on an upgraded booster/master from Frank's Pick-em Ups in Olympia. I'm looking forward to the improvement! No more floppy hood! Check out those new light bulbs too! Edited March 17, 2019 by carterb 1 Quote Link to comment

carterb Posted March 23, 2019 Report Share Posted March 23, 2019 Got the rear control arms and front sway bar arms painted with POR15 last week. Met up with the boys. Jeff completed machining the rear disk brake brackets and here he is showing Sam the finer points of five finger brake line bending. Tried to clean up the inside of the car with simple green. It's pretty gross from being put away wet and then sitting outside for months. Got the seat re-installed and then mounted the new wink mirror. Installed headlight doors too in an effort to make the front of the car look more like a 510. Speaking of the front of the car, just thinking of a new tow hook and possibly a removable air dam. Rear spoiler too eventually? Rear end ready to roll again! 1 Quote Link to comment
carterb Posted March 29, 2019 Report Share Posted March 29, 2019 (edited) Another evening working on the racecar, another few things removed from the list, another couple things added to the list. Jeff pulled one of the struts apart to investigate why they were coming loose at Pacific Raceways (I think I left that off the report) Turns out it was a good thing as a weld booger from the inside of the sectioned strut housing had nearly cut the top off of one of the strut inserts! I filed the strut housing smooth and ordered new inserts - should be here next week. We also found that the strut cartridges were sitting on spacers that were not a uniform thickness - which probably explains why the strut nuts got loose. All that force on the high point of the spacer eventually smooshed it a bit creating some play. We will need to address these as well. Oh yea, and one of the strut housings was full of seed pods. Whatever?! Installed the new pads on the front brakes and then set about bleeding the system. Ran out of fancy purple synthetic brake fluid so had to make a run to the store. They turn brake rotors FYI. Brake bleeding was further interrupted by a poor seal from the brake line to one of the rear calipers. Jeff and Sam were able to fix with brute force. Speaking of brute force, Sam commented on how much the firewall would flex when I pressed the brake pedal. Jeff thought this would be a good time to try out the T3 brake master cylinder stiffener/support/bracket. Here it is with the screw backed off so you can see how much the master cylinder moves. http://datsun510.com/uploads/monthly_2019_03/03272019_swamp_thing_(1).MOV.e2aeb4aa760ade0a5f99814e86978bce.MOV And here it is with the screw pressing on the end of the master so you can see how much the bracket just moves out of the way. http://datsun510.com/uploads/monthly_2019_03/03272019_swamp_thing_(2).MOV.6511ca2da9edf6d0a130b6631b125d20.MOV Not very effective, partially due to being mounted to thin engine bay sheet metal but mostly due to poor engineering. The mounting holes are at the far edge of the bracket so it just happily rotates out of the way. I added another mounting hole on the inside of the bracket and this cut the deflection in half. Don't know if it really does anything but oh well, we've got a cute little T3 advert under the hood now anyway... Since we replaced the rear trailing arms, Jeff needed to notch them for wheel clearance. Getting closer... Edited March 30, 2019 by carterb 2 Quote Link to comment
carterb Posted April 1, 2019 Report Share Posted April 1, 2019 I feel like we are running short on time... Saturday I prepped the new hood for paint and welded up the rack near the nose on the front right. I tried to repair the front valance I had too but the steel around the rip was half rusted away, half burned (front right corner of the car caught fired), and paper thin. It was beyond my ability to save. As low as my welder would go I just kept blasting holes in the metal. I could have backed it up with a patch but I think at this point, we'll just use the valance off of Corey's car. It's wrinkly but so is the rest of our racecar. : ) Hood ready(ish) for epoxy primer. Shiny! 1 Quote Link to comment
