    Yep, we are really happy he walked away. Haha, a racing Jaguar! I will see what our plan is. Still really like the 6262 and not sure if we are ready to give that up just yet. But also not sure we are ready for the time, money and effort of a new build. We will see. BTW, I saw you guys get an honourable mention in a Lemons wrap up video the other day. Nice work!

    Well... its been a while since I posted any updates on here. We installed some nice little LED daytime running lights. Replaced the control arms (ball joints) with new. And we moved the surge tank to the rear. We went to race the final race of the year at Calabogie Motorsports Park. A great little circuit with some really tricky technical turns and some plat out 4th gear high speed stuff too. The car was really loose for some reason. (RacerX, similar or more so to how it was on the Sunday at Watkins when running the Nankang tires on the rear). I have no idea why, our alignment settings should have been the same as normal. Maybe the rear shocks were going? I personally like it to drive more neutral with more of a tendency to push. Anyways, doesn't really matter now. My dad went out and had a solid stint. Not the fastest, but he improved his lap times significantly over the first half then settled in to run very consistent laps in the 2nd half of his stint. Our second driver went out, and one hour in lost the rear end in T1. T1 is a fairly flat out 4th gear corner with only a slight lift before going back to full throttle through the apex to drive out of it. Car spun, went straight to the inside wall. Front right bounced off of a tire wall immediately sending the rear right into the concrete wall directly beside it (its actually a temporary tire wall backed by concrete blocks to guard the lower pit/paddock entrance). Car is looking like a complete write-off at this point. not sure if anything will be salvageable from shocks at all corners, to engine mounts, headers, surge tank, etc). Belts will go in the garbage, same with drivers helmet, still looking into whether or not the seat need to go in the garbage too. Good news is that the driver walked away without even a scratch. Says he doesn't even really feel stiff this morning. Checked out for concussion at track and later at hospital and was given full go ahead both times. We are all pretty bummed about this one. All really loved that car. But all VERY happy driver walked away. No idea what we will do in terms of building a new car as life and funds aren't looking all that kindly upon that prospect at the moment! Eventually I hope. Will give a more detailed run down of the accident and "learning points" of where we could improve our build as we get into tearing down the car.

    Awesome! Congrats guys! Was following along on race monitor and was excited to see you steadily climbing the leaderboard.

    By the way, to RacerX being down in Texas, I hope you and family and friends are all safe and sound down there. Stay safe man.

    Looks good. Im a bit surprised that the gauges are hard to read in the sun. Interesting though, RacerX said he replaced the digital gauges so he could get more accurate readings from his drivers. I always thought my drivers were better at reading our dial style gauges, but have had some radio messages that are wildly inaccurate when I go back and review the video. I like how the dials basically say "all good" if the dial is pointing straight up. I think if I were to do it over though, I'd go with digital and use the idiot lights for high water temp and low oil pressure.

    Hahaha, Id be knocking on wood or crossing your fingers saying stuff like that! Might as well be waxing the car while your at it!

    I was thinking about that actually. Our diagnosis was just a worn out caliper. Replaced both rear calipers and all is well again. The guys we buy pads from at Frozen Rotors say that try great calipers as a wear item and replace once per year. We will be doing the same now as well along with our normal service and lube before each race.

    I cant seem to find a picture of the final produce, but we simply riveted in an aluminum plate into that opening, then cut a hole big enough for a muffler reducer. We cut it all up as it was way too big then left two small tabs from the front/big part that we could bend out and bolt the whole thing to the aluminum plate. We use an old vacuum hose (2"? 2.5" maybe?) and it routes really easily through to the wheel well. At the brake end, we inserted a short length of PVC pipe for strength/rigidity and use one simple ziptie to hold it in place on the lower control arm. Points pretty much in the direction of the center of the rotor and is maybe a couple inches away. I agree, that with the big brakes, there should be no issue with fade with or without the ducts. Though, our brakes last so long that I don't want to mess with increased wear by letting them get hotter than they do. SO we just run it as it is.

    As to the vented hood, we tried to keep the vents in the front 1/3 where I think (with my limited aero experience) the pressure would be lowest. I would be more concerned about the lack of headlights. Lots of little areas in those areas for air to bypass the rad. I also agree though, that from what we have seen with the V6, high temps are a symptom not the root cause. The cooling system should be enough to keep up. Side note: the 98+ radiator is MUCH thinner (like almost half of the width). I think that rad doesn't have enough to keep up, but the 93-97 should be ok. Disclaimer, we run a thicker aluminum rad.

    Who me? Non stock tank??? I don't know anything about Mazda 626 gas tanks.... But yeah, we put in the tank we had from the 98 we used to run. What did you do for venting? We removed all of the emissions/carbon canister stuff and tried to use that same outlet as a vent. It didn't work perfectly as there is some funny routing inside of the tank and it catches an air bible before it is totally full. We simply stuck a big drill bit in that outlet and drill into where it "turns" toward the drivers side. But the tank was out and empty when we did. I THINK (can't remember, would have to go back to my notes) that we used the 93 filler neck as it seemed a bit larger diameter. though, the critical path is the inlet bung to the 98 tank as it is a smaller diameter.

    Cool, yeah, Ive heard that about replacing just the ball joint. Good to know. Hahaha, I didn't even think about the brake dust. But yes, good point!

    We finally got around to tearing the car down a bit. Found some good stuff. After a bit of a look at the exhaust headers and comparing to some pics on the internet, I am fairly certain that it was the EGR bung blowing out. That would coincide with the big noise when it failed. The driver (my mom was in the car at the time) radioed in saying she ran something over but didn't know what. On the video, you can hear a bit of a bang and the exhaust note changes right away. All good though, it was fairly easy to get off once the transverse subframe is taken off, and $20 for our exhaust guys to weld a little patch over it (man, we need to learn to weld!). Our car wont sound like a tractor anymore! Then we about tearing apart the front suspension to see if we could find the noise/vibration. There was still no end play in the wheel bearing. Though, after crawling around under the car we could see the ball joint wiggling around as we were trying to shake the tire/wheel. After getting the struts and spindle off you could definitely tell that the ball joint had gone. So pretty sure we have found the problem. After looking around, we weren't able to find any standalone ball joints for a decent price. So our plan is to simply replace the entire lower control arm with a new part. Is there a better way to do this? While the spindles are off, we are also going to go ahead and replace the wheel bearings. They have around 70 race hours on them, so Im a bit surprised they haven't failed yet as it is. A few other items we have on the list are not imperative, but we are getting at them now as there is plenty of time before we race again in September. - Relocating the surge tank to the rear wheel well from its current location in the engine compartment. It may be a bit more susceptible to a rear end collision back there but should be pretected well enough. It does get it, and all the additional fuel lines, away from heat sources though, so I think safer in the end. We will move the battery box to the far passenger side trunk area to make room for the surge in the spare wheel well. Then plan on covering it over with a thin sheet of aluminum. - Make a hanger for our steering wheel. We are finding drivers tend to push it up towards the windshield and it has broken a couple of the defroster lines. So want to get away from doing that. - Adding additional venting to the fuel tank as we still have trouble dumping a 5 gallon jug in less than 20 seconds without it overflowing. I am hoping this time we will finally get enough venting, otherwise we may need to look into a dedicated bung/fitting welded into the top of the tank to solve it. - We want to block off the hole under the fenders that goes from the front wheel well into the cabin. We are getting a bunch of rubber in the car, and at times hot rubber flying into your eyes. Im hoping that blocking this area will solve that, or at least cut it down a bit. We are planning to cut and push in the rear part of the fenders. This should give a bit of venting to the tires/wheel wells and also block off that hole. Any remaining gap we should be able to get pretty easily with some Coroplast and gorilla tape.

    Those are going to be perfect. Nice choice!
