    So how about some of you in the top 25 raw time...

    in SCCA Solo Discussion

    Posted

    So I learned a pretty important lesson this past weekend about distance traveled and related elapsed time and I thought I'd share it with the class.  Mat Leon and I both ran GoodGuys Autocross and we both were data logging with Solostorm.  Yesterday we shared logs with each other and did some comparing.  The two logs compared below are my 42.3xx I ran on Friday and Mat's 42.4xx he ran on Sunday I believe, same course.   Please disregard the total elapsed times on the logs as they are incorrect, I think we have our start and stop triggers configured differently.  What is more important are the individual sector data points.

    Here is sector 2 right after the start, notice they are pretty close between us on just about everything.

    Sector 3 shows Mat traveled 7 feet less with both of us averaging 28.6ish mph...and he picked up 0.25 seconds on me.

    Sector 4 was pretty similar as was sector 5.

    Sector 6 got pretty interesting though.  Lance traveled 27 feet less and gained 3 tenths of a second.

    Sector 7 was a huge jump though.  Mat traveled 47 feet less distance at roughly the same average speed and [b]picked up 1.271 seconds on me!![/b]

    I returned the favor in sector 8 though.  33 feet less and picked up 0.973 seconds.

    Then he gained back in sector 9 by traveling another 33 feet less and picking up 0.622 seconds.

    I haven't done the math yet...but just imagine the time we would have saved if one of us had hit all of those sectors as tight as each of us did separately!  I'm guessing what, 4 seconds quicker at least.  No wonder we were so far behind some similar cars...  I always knew distance traveled was important but this really brought it to light to me.  Hopefully this helps some others in this area as well.  I know I'll concentrate much harder in the future on limiting the distance traveled while on course. 

     

    Hopefully this also shows some just how helpful data logging can be, anyone running Solostorm can upload logs for others than ran the same course to download so they can compare and learn from as well.

    Thanks Matt!  Certainly helps to hear how other's attack a course to find time.  A lot of really experienced racers like to say you need to be fast in the fast parts...  This is what I'm currently working on.  I've made a few changes to the car recently and they allow me to do things that I couldn't do with it before.  Now I'm just trying to figure out how to do that things faster...  😄  

     

    BTW, I really love having Solostorm logging in my car during runs and we now have 3 of us comparing solostorm runs after races to see who went faster and where.  It would certainly help more if we could do it in between runs but that is pretty difficult if not co-driving.  Mat, James and I can all upload our runs to a cloud, then download each others and compare one right over the other.  It's pretty cool...

    Thanks Sid and Brian, I think you are both correct.  The run I posted the video of was 1 second slower than my 2nd and 3rd runs which were both dirty, so I had to use a bit more caution.  Brian killed it in the slalom and I could definitely see the extra speed and aggression in the braking zones as well.  I was trying to carry as much speed as I could in slalom without getting behind and it's tough when it's imperative that you don't cone out.  Even that 1 second faster run would have only moved me up to about 28th raw time where I'm typically 15-20th.  I guess it just wasn't a course for me and my ride.  Still fun trying though.

     

    I need parts installed on my Miata.....looking for a good home mechanic/racer.

    I have helped several people on here update parts on their cars and have built my car pretty much from scratch, so I'm sure I could help.  I also have corner scales and the equipment to do alignments.  I'm just not sure what kind of time frame you are thinking nor how to decide what is "paid fairly" as I'm not a full fledged shop with a rate schedule or anything like that.  I'd be interested in talking options with you though.  I'm up in N. Peoria near 67th Ave and Happy Valley if that makes a difference.

    Does anybody here do their own alignments?

    I do my own and helped helped several others here out with theirs.  I have turn plates and caster camber gauges which are not totally necessary but really speed the job up.  

    I will advise against buying the QuikTrik alignment tool set if that was a consideration as it just sucks.  What Dan posted above will get the job done, anything more than that just helps do it quicker.  Before I had turn plates I would put masking tape on the steering wheel next to the column and the column itself and I'd mark both with wheels straight ahead and wheels 15 degrees turn right and 15 degrees turned left.  This helps with repeatability when making Caster readings and changes.

    I use contraptions that I bungee cord against the wheels that allow me to use the caster camber gauge and tape measures on them without removing them from the wheel.  I'll try to find pictures of them in action and post them.

    Corvair in CAM-T

    So, this is a good conversation to have and I've been thinking about it as well.  To be technical, Sean's F150 shouldn't be in CAM T either.  It's probably my fault as I told him to register in CAM T without really thinking about it, as it just looks like a CAM T build to me. 

    Personally I love having all these old builds in CAM T and yes, we are all pretty competitive...that's what makes it so much fun.  I also understand if others in the class do not want to race against the technically non-CAM T cars.  If anyone does object, please speak up and we'll get everyone classed appropriately. 

    To me, the beauty of the CAM classes is we really don't worry about this kind of stuff because for the most part, most of us aren't supposed to be here anyway.   🤣

    Thanks for the feedback Nick.  I'm doing my homework assignment now.  😃

    I've been told in the past that I drive off the front of my hood and by memory, but in my defense...my car demanded too much attention to what it's doing right now to worry about what's coming up.  🤣  Lately though the car is MUCH improved and I have been trying to concentrate more on looking ahead.

    0:07 - Looking at the exit of the slalom. 

    I was probably looking at the 2nd pin in slalom, I did get behind in most of my runs in the last two pins and never really got the speed I wanted thru the last 3 pins

    0:12 - Head turned way left looking at the exit of the box.

    Pfft...I'm maybe looking at the first inside pin trying to set up getting into the box...and still had trouble with my braking zone.  At 15 seconds you can see me glance up to find the exit once I didn't knock the wall down on the back of the box. 

    0:22 - Head looking right out the passenger window at the corner exit of the sweeper.

    Looks like I glanced to the exit at about 26 seconds, again just past the apex.

    0:32 - Looking all the way down at the exit of that tight left.

    I glanced at exit about 35 seconds.

    0:38 - I was looking at the cone that started the right hand turn at 0:41.

    I feel like I got these last two sections down pretty well, was pretty happy with my car placement and speed.  Maybe looked ahead a touch later than you but still knew where I needed to be.

    0:41 - Looking out the passenger window at the entrance cone of the final sweeper.

    I completely missed looking ahead here.

    0:44 - Looking at the final cone just before the finish so I could get nice and close to it. Where did you end up in relation to that cone in your video?

    So I looked ahead at 44 at that cone but still didn't get my arc right through that turn.  I knew where I needed to be but just didn't do what my car needed to get there.  Both there and the entrance to the first box I overdrove the entry multiple times and pushed the front trying to turn in. 

    With the old diff I would have entered these much easier because the car would upset so easily there, with the new diff it was so much more confidence inducing that I was overdriving in.  I need to find a happier medium getting in there which would let me carry more speed through apex and also get back onto the gas earlier on exit.    

    Let me know if this helps at all.

    Yeah, it helps a ton to talk through a run like this. Thank you for taking the time...  I feel like I'm at the point where I need instruction again to really fine tune my ability to minimize time on course.  I'm using Solostorm and that helps after the fact but without a really good co-driver to compare to during runs, it is hard to use it to get better in real time.

    Super fun course and a well run event, thanks to all that put in the extra work to make these happen.

     

    Here's my fastest 46.395 run.  I was learning a new torsen diff that made the car completely different and I picked up time on every single run.  Thought I put down a pretty decent lap until all the fast guys ran in the afternoon session.  Really hope some of you will post videos so I can see where I left all the time on the table.  Now that the car will do things it could never do before, the driver needs to learn how to make it do those things faster...
