  1. Car looks awesome! Nice work
  2. A bit of decent video. Here is me starting on Saturday. Went from around 32nd taking the green to as high as 3rd. Handed the car off in 5th after nearly 2 hours. and here is another one in the rain of me finishing on Sunday. Was having fun and pushing hard. Maybe too hard!! I backed off after my 2nd spin. Fun to watch at least!
  3. 10th and 13th overall. Pretty solid weekend all things considered. I wondered about the heat, especially seeing as the previous race was in perfect fall conditions (10-15 degrees C, dry, sunny). I will find some time to pull out our lap timer data and see what kind of corner speeds we had vs speeds on the straights.
  4. Hmmm. Wonder how a diff issue would be diagnosed without pulling it apart? Maybe a good opportunity for a LSD anyways! Extra bung... I was thinking that too since it was so perfectly round looking. Will get a better look once they come off the car. Im not too concerned about the dents. Will probably just bang them out. It was such a nice looking car before that though!
  5. Yep. We were thinking that too and will definitely do. But, it was definitely a rotational noise/virabtion? I.e gets faster as the car gets faster.
  6. Reposted from the post above to highlight: I got in the car to finish off the final hour or so. I started to notice that the car had developed what I think is a failing front left wheel bearing. It wasn’t too bad, so kept pushing on. There was a fairly strong vibration and noise in all right hand corners and it would disappear altogether in left hand corners. So on Saturday night we tried to do a bit of trouble shooting. Jacking the car up, we can find no end play in the wheel. The wheel feels solid when trying to wiggle it. It also seems to make no noise when spinning (straight or with steering wheel cranked) from either the bearing or CV joint. At this point we decided to just run it the following day and see how far it would make it. Amazingly it made it the entire 8 hours. Again I finished off the race and seem to feel like the vibration hadn’t really got any worse. Weird. So now we can get into the tear down process and see if we can find the issue. Any thoughts?
  7. We just successfully finished another 8+8 hour race this past weekend! It was Canada's 150th birthday too on Saturday, so what a way to celebrate! The weekend went well from most accounts. Everyone had fun, each of the drivers set new PB lap times and we were racing fairly competitively for most of the weekend. I started on Saturday morning in the rain. Was somewhere around 30-35 place when the green flag dropped and I proceeded to put the hammer down! I don't mind the rain and slippery stuff and was having a blast doing it. Picking cars off one by one and ran as high as 2nd place (out of 45 starting cars). Heck yeah, showing everyone else what a Mazda can do! At around 1:45 while running in 4th place there was a Full Course caution, so we pitted and changed out drivers. The car ran well until my mother got in. Yes you read that correctly, my 69 year old mother drove her first race this past weekend! She did really well and brought the car home safe and sound which is rule #1. Over the radio it sounded like she was getting pretty tired, so we brought her in after about 40 mins. Until that time she was looking to be getting more comfortable and was bringing her lap times down. She had called in over the radio that she ran something over but didn’t know what. A big bang under the car while going down the back straight. Car seemed to be running ok though, no worries. When she came in it was fairly clear that there was an exhaust leak somewhere around the reader header or flex pipe. Nothing we could do so we soildered on for the rest of the day. I got in the car to finish off the final hour or so. I started to notice that the car had developed what I think is a failing front left wheel bearing. It wasn’t too bad, so kept pushing on. There was a fairly strong vibration and noise in all right hand corners and it would disappear altogether in left hand corners. We ended up finishing in 10th place overall, qualifying us for the year end Championship race which was a bonus. All in all, I think we did pretty well too, very happy to be top 10. So on Saturday night we tried to do a bit of trouble shooting. First off, we had no spare wheel bearing and couldn’t find one as all stores were closed for our national holiday Canada Day long weekend L. Also, I tried to get a set of used spindles from a wrecker last week, but when I went to pick them up on the way to the track on Friday I found that they weren’t from a 626. So we had no backups ready. Jacking the car up, we can find no end play in the wheel. The wheel feels solid when trying to wiggle it. It also seems to make no noise when spinning (straight or with steering wheel cranked) from either the bearing or CV joint. At this point we decided to just run it the following day and see how far it would make it. Amazingly it made it the entire 8 hours. Again I finished off the race and seem to feel like the vibration hadn’t really got any worse. Weird. So now we can get into the tear down process and see if we can find the issue. Any thoughts? Now, to the exhaust leak. I started by check the bolts and gaskets on the headers and exhaust. All good. I started looking around a little bit more and found what can be seen in the picture below. It is hole, approx just smaller than a quarter, blown out of one of the exhaust header tubes. I would almost think it was the bung for the O2 sensor, but the sensor is actually further downstream and still attached. So that would explain the bang that my mom thought was the car running over something. It didn’t seem to effect performance all that much, but was sure causing a whole bunch of back firing when lifting off the throttle! Blowing flames every time too. At least it looked cool! I have no idea why this would have happened (cheap Chinese steel?) or how we are going to go about fixing it. Hopefully once it gets pulled off, we can get a patch welded on and not have to replace the whole thing. So we raced the remainder of Sunday without real incident until my final stint. It began to rain quite hard and I was again having some fun in the slippery stuff. I ended up going around the outside of T9 when a yellow CRX decided that it wanted to be in the lane I was in…. Not sure how he didn’t see me, but such is life I guess. He gave me a pretty good dent on the rear driver’s side door and spun me around. Luckily no other cars picked me up in the process and I was able to drive away. He also managed to miss the rear wheel altogether so the car ran strong and didn’t have any alignment issues post hit. I ran the rest of the race and was pushing hard until a few spins made me rethink how fast I really needed to go! I backed off and just brought the car home from that point on. We ended up in 13th place overall, not bad all things considered.
  8. Here are a couple from this past weekend (July 1-2, 2017). The trusty 626 continues to pay us back for saving it from its previous life!
  9. As bit of an update after we raced this past weekend. The 255/40/17s definitely had subjectively more grip than the 235/45/17s (I don't have any hard data to back that up and haven't looked at our lap timer data yet). I was able to go harder into many of Mosport's corners, stayed flat or nearly flat through T4, lift or slight breath on the brakes into T1 as opposed to a decent stab previously and played around with little to no brakes at the end of the straight into T8. Though, also subjectively I feel like they were a bit softer on the sidewalls without a stretch to the tire and seemed a bit less reactive. We ended up running 0.5 seconds faster than we did last year on the 235s. Though, it was a totally different day, much warmer, more humid, the track was damp for parts and admittedly I was really hung-over for Sundays race!
  10. Is this something you guys do on a regular basis??!! Heck, RacerX even showed up and got our first ever flat spotted tire started on its way to square!
  11. Saaweeet!
  12. Hmmmmm... interesting! Will definitely keep that in mind!
  13. Yes, dont disagree with a theoretical maximum size. It could even be that 245 is somewhere near the limit for that power. As I mentioned, hopefully i can contribute some hard (and subjective data) to the topic after this coming weekend. I can also note that it sure seemed (by the butt dyno) that the 235/40/17 had more getup than the larger (by a significant margin actually) 235/45/17. First prize in my mind is finding a similar lightweight 15" wheel in a 9" (or 10 even) and go with a 245/40/15. At the same time find a set of wilwood calipers and pair them with a smaller (read lighter) rotor as I feel like our brakes (and your Speed6 even more so) are a bit of overkill. Ive challenged my teammates to find a lightweight 15" wheel and I will buy and make the upgrade! The only stuff we have been able to find so far though is in 4x100 bolt pattern Also, per a previous comment, the Mazda 6 (and subsequently Speed6) wont fit inside of a 15" wheel, but will fit in 16" or greater.
  14. I respectfully disagree with you guys! Inactive, did you buy the ones on the chump forum? Screaming deal, if I was closer I would have bought the whole lot of them and the tires! make sure you get some hub rings to fit them properly. They are pretty cheap and easy to find on amazon or other sites. As for the RPF1s, the 17x9 is only 17 lbs. the 8 inch will be even less. I would say it would definitely be a net weight loss in the end. There won't be any trouble getting heat into the tires (unless you guys drive really slow ). But the 245 may be a bit wide for an 8" tire, maybe? 225 should give a better feel (stiffer sidewall with it stretched to fit) but I think the extra rubber will be faster overall. We just did a test of our new 255s on a 9" wheel, but it's hard to say how it was as I wasn't driving, just some of my teammates were. Will hopefully have some hard data for you as we race next weekend. Mosport baby!
  15. Currently running around 350 points. What all do you have included into that 400 points? Cams would be a big one, but you should be able to get away without charging for springs right?
