PanAmerica proxy on the Targa Burnaby

PanAmerica proxy on the Targa Burnaby

Postby oldslotracer » Sat Sep 30, 2017 5:35 pm

Friday is our regular race night, so we decided to do a Concours for the PanAmerica Proxy cars and on Saturday
we ran all the cars on the Hillclimb just for fun. Here are the best times. Each car was run at least three
times at 9 volts and I videotaped the second run of each car, so the times in the video may not match the
car's best run. Don M was the driver, consistently one of the top 4 guys on the Hillclimb.

#63 19.90
#157 21.29
#171 21.42
#21 Jag 21.43
#356 21.62
#45 22.01
#129 22.02
#20 22.15
#44 Ferrari 22.36
#77 22.37
#152 22.43
#6 22.52
#149 22.65
#54 22.66
#4 22.77
#21 Merc 22.87
#2 23.06
#33 23.13
#44 Studebaker 23.68
#113 23.68
#78 23.90
#259 24.07
#10 24.69
#14 25.29
#31 25.65
#11 26.05
#23 26.26
#53 29.82
#12 33.08

We hope to do the qualifying on the Targa track this week and the actual race soon after that.

The best part was watching shotgundave's little VW roof-racked beetle charging up (and down) the hill! :handgestures-thumbup: :handgestures-thumbup:

Certainly no shame in coming in second to Shotgun's superb looking VW in the concourse... We're thrilled! ....how do they keep the luggage from flying off that thing anyway? Great video of the hill climb event and yes, excellent driving! ...but, I'm sure Alejandro must have wet himself in the passenger seat of the number 14 car...

Thanks for the qualifying effort. I see my Gift Card chassis made 6th. Nice to see it still has legs after all this time.

Are you guys going to be doing the Targa this year?
Cheers

Thanks for the run Gentleman. Looks like the #33 has lost its pace. Great to see the Retro Racer cars up front and you can never count out the 149. The race should be tons of fun.

We're going to run the cars tomorrow (Sunday)

One of our local guys would like to run the cars on his wood track as well, if that's OK with you guys. If not, can you let me know where to send the cars next?
Thanks

Hi Luf, we're all looking forward to seeing the race tomorrow at your New Targa track! Always a treat to have our cars run on the Targa!

To keep on schedule as much as possible, I'd like to have you send the cars to Dariusz in Edmonton after you finish you're Round. I PM'd you his shipping address just now. These cars have been away from their builders for about 8 months now, so we'd like to get Dariusz's Round and Bob Chapman's Round run and in the books so that I can return the cars. Thanks.

WOW that is an amazing track! I wonder if the passenger spilled her Coke in the 113!

Another round in the books! And without any further ado: the gory details:

Image


It was an interesting morning! Luf did the qualifying at 10V but because of the lower power of the motors we decided to run the actual racing at 11V. For some of the cars that was too much but for the fast end of the field we could/should likely have run at 12V. Because of this it should probably be no surprise that the fastest race lap was on average just a bit over half a second quicker than qualifying.

And as I have likely mentioned before on the forum: we tend to take our responsibility towards the car builders pretty seriously out here. We really try very hard to ensure we do the absolute best that we can for each and every car. To this end I had identified a couple of indices to reflect how well or how badly we have been able to tap the full potential of each car. These indices are:

1. Speed index: In essence this is just a measure of how the fastest lap we obtained with each car in each lane compared to the qualifying time. For arguments sake: if the Q time was 9 seconds and a driver did an 8.5 second lap the speed index is 9.0/8.5 = 105.9%. The bigger the number, the better we did, i.e. the faster the best race lap in a lane was.

Obviously anything approaching (or better yet, exceeding!) 100% is good. This time round we were helped by the fact that qualifying was done at 10V while we ran the races at 11V. The speed indices in this round are higher than average FWIW.

2. Consistency index: Over time we have all come to realise that turning one blisteringly fast lap and either deslotting a lot or running the remaining laps a lot slower is of no use. This index basically says how many laps we were to able to complete with each car in a heat in a lane compared to how much we could have doen had we completed EACH LAP at the best lap time in the race! Now we all know achieving 100% is totally impossible: firstly the first lap is a standing start lap: you lose a LOT of time there. Then you slowly start building up the speed as you become more familiar with the car. In the mean time these slower lap times drop your "Consistency index". And then the dreaded deslot! One delsot totally kills your index.

Anything over 90% is pretty good.

From this we then get an "Overall Index": this is just the two aforementioned indices multiplied together. What this tells you is "how many laps did a driver complete in a lane with a car compared to the number of laps that he would have completed had he completed every lap at the qualifying lap time for that car?" Obviously anything coming close to 100% is great!

So how did we do? I calculated these indices for each car in each lane and averaged it per lane and in total. These averages are as follows:

Image


Now I got to tell you these are pretty good numbers! Consistent across lanes/drivers and consistently quick. Note that over time I have come to accept that lane 2 is the quickest of the three lanes with lane 3 around 1/10 of a second per lap slower and lane 1 another 1/10th slower again. We were able to minimise the impact of this quite nicely actually.

And there we are: round completed! Great thanks to Murray and Duke for helping with the driving, Don for marshaling and Luf for recording and editing the soon to be released "Round 9: The Movie!"

Thanks for running this Round, Luf and, Alwyn, thanks for posting the results and for your usual excellent analysis of the data.

Congrats to Mitch58, our dear departed friend, Keith and chrisguyw on their podium finishes! :text-bravo: :text-bravo: :text-bravo:

Great to be able to have a Round run on the famous New Targa; always a thrill to see the cars running on this track!

Thanks again!

Wow, that was a surprise, my old Vette must like that track. Thanks for the run guys, looking forward to the video. Of course I like all of the videos from that and previous tracks.
