Banked Oval at 135mph

Yesterday we did a little run at the California Speedway in Riverside, running the Roval auto competition course, which is 2.8 miles and includes the entire front straight, the banked oval turns one and two (14 degrees) and halfway down the back straight, before cutting into the twisties.

Bo made it in his stock coupe and had a great showing, both of us learning a lot, and going off track a couple of times on the twisties part of the infield course (you get over 100mph on two sections there, so it is not a dinky go cart set up on the infield by any means). Arash and two buddies showed up for the afternoon session, and I gave both of them a ride for a few laps to get a sensation too. It was great fun, though I am sure that after a couple of laps they would have preferred to be driving than riding shotgun. There were no other G or Z cars there. Bo had a friend in an RX 8, and Keith in his Saleen Mustang, both of which were very nice cars. I think Keith boiled his BF early and had to leave, but David's little rotary, though needing some more hp on the straights, was a great corner carving machine, and just looked super.

I will do a longer write up and pics and video as in the past, but wanted to do a quick preview for your enjoyment.
This goes into the category of lessons learned without negative consequences, but fortunately so.

The temps were going to be in the high eighties, low nineties, and after running Willow Springs in high heat and having to back off, I wanted better cooling capacity, so put in a deeper oil pan. Not precisely sure of how much oil it took, but it was between 6.5 and 6.75 quarts. That worked fine.

I wanted to have the adjustable front camber control arms in, but there was a glitch and they did not get put on. I thought that for the oval and high speeds it would be a very good idea to have a couple more degrees of camber for that day. Major understatement.

My fastest lap of the day....by four seconds...was the first one. (Hint of what is to come). This is notwithstanding the fact that as the day went on I probably cut ten seconds off my time on the twisties from the first lap, maybe more.

The answer to that of course, was speed through the high banked oval, my first experience with that. I read everything I could find on it. Studied in car videos of excellent drivers taking it. Analyzed the line and turn transition. Figured that 135mph was about right as a reasonably quick, but still conservative run speed, then I would carefully consider whether more would be warranted. Blah blah blah.

The car is set and warmed, we launch at the bottom of turn one from the pit lane, work up speed, transition to the bottom of the bank at turn two, work down the back straight and through the twisties. Feeling good, car is purring. The inside part of the course is flat, and has some challenging parts for my skill sets, perhaps not so much for the advanced group drivers who are not as challenged by double apex hairpins, and a diminishing radius number that gets me off track later, but I had a handful and loved it all.

Come out of the last turn and enter the front straight way at the back of the high bank turn four exit, at about 85+mph. Drop the hammer and upshift to fifth and then sixth. (Yes, you heard it right, sixth gear and all she could give, WOT with the supercharger and it SCREAMS with the windows down and reverberates off the 11 degree bank wall along the straight). Get it settled and just exactly where I want to be and have her dialed in exactly at 135mph. "Oh" I think, "this is too cool, I am doing it exactly as planned".

Transition to the turn and hold it on the line like it was a strand of dental floss. About half way through turn one I realize my fanny has gone bloodless from the cheek clench.
This is way too freaking fast for my comfort zone. The car is handling beautifully, stable, no sense of give or wobble, I stay in the throttle and at this point am much more concerned about doing anything to upset the balance of the car as much as a micron. No lifting, no wheel motion, no farting, no swallowing, no breathing. Zip through and down the back stretch. The car that was behind me when that section started is not even in the rear view mirror any more. Never went above 120mph in that turn the rest of the day.

About two hours later a viper kisses the wall at serious speed and the entire right side, and both wheels and tires are thrashed, rear window pops and explodes out and basically winds up looking like the incredible Hulk kicked it in the rear. Nobody hurt. But zowiee.

I loved the experience, the facility is first rate (I even got my own interior garage spot!). But notwithstanding that I had noodled out all the particulars, and fortunately was correct, the intellectual component of driving that portion of that track was way more advanced than my emotional and experiential quotient. Lucky. It will be only after some more experience and working up to it that we go though that little section like that again. Lesson learned is this simple one, and fortunately I survived it. It is possible to be wrong in your analysis, after all. Do not put yourself in a position where if you are wrong, you pay a nasty price. I was right, but I realized only after I was committed that...holy guano Batman....what if I had been wrong??!! Recovery was outside of my skill sets. Only when I get those dialed in, am I going back to that situation. And then working up to it. If there had been a lump of coal on my seat, it would be a diamond right now.

What a great story, Ed. Sorry I couldn't be there to lend support and ride shotgun with you. Sounds like you had fun though.

Re: Banked Oval at 135mph

I think the best part of the day was i locked my keys in my car. But best of all i locked them inside the trunk. For 30 minutes we couldnt figure out how to open it. Called infiniti, they like usual put me on hold for an hour.

Bo came and said what the problem, told him we can open the trunk to get into the back. He hops right in and opens the back seat and Vuallla we are inside the trunk and i get my keys and were off back home.


Ed thanks for giving my friends a ride, they reallly enjoyed it. You got 2 more people hooked on open track days.

Re: Banked Oval at 135mph

Unfortunately I couldn't make it out there at all Sounds like another eventfull track day and A-okay at the end of the day. They way I'd prefer it.

Arash, that is comedy ... after the fact, of course.


Oh and how did the video footages turn out guys? Was the external mic okay?

Re: Banked Oval at 135mph

Clint:
I used my mic and adjusted the program on the camera and it worked just great, so I need to return your mono mic, we lucked out and did not need it. Arash got his camera attached to my rear window, but it got jolted around and turned itself off, so no pics from the reverse angle, at least not this time. We will get it worked out for the next adventure.
No G's were injured in the filming of this feature. But I did go off track TWICE. They said that the biggest screw ups are in the intermediate group, and certainly I seem to have live up (or down) to that expectation. My front tires are cooked, the rubber on the outside is just worn off so no more track days for those bad boys. The big stoptechs work like gangbusters, and when I have the pebbles to go deep and trust them, it really drops the laptimes. But wow it makes your peepers widen when you come down off that turn at 120 mph plus and you have a ninety degree left with tire stacks on both sides that you need to thread through. Good stuff. Definitely, this is a track I want to run again. Sears Point is still my favorite so far, but this is a good run and a fabulous facility.

Re: Banked Oval at 135mph

The best part of this experience, specially being my first time on the track; was the fact that there were only handfull of cars on the yellow group. My most concerned was running into or being run over by other cars. That few of cars spread out in a 2.88 mile track....no worry at all. I would definitely like to run with this group (SpeedVentures) again. They seemed to be a little disorganized at times, but you can't beat the lack of participants. Sure hope they make some $$, so that they will do it again.

Re: Banked Oval at 135mph

Bo,
I know what you mean by that. It's probably the loose and laxed nature of the club. In some ways, It's a good thing as you don't feel like you're being 'watched'. Speed Ventures has been around for a while now and I have been tracking through them for years and believe they will be around for many more years to come. Participant numbers vary from event to event and dependant on the time of the year.

Hope to see you out at the next one. I'd like to do ButtonWillow next.

Cheers,

Clint (THX723)

Re: Banked Oval at 135mph

Clint:
Bo was right about the stacking of the classes. On this track on this day it was the advanced group that had the largest number of cars, by far. Partly this was because it was a race day, and the second run of the morning was qualifying for grid position. The intermediate class had several guys that were not going to race, but were advanced group drivers and cars, and they just stepped down to get out of the craziness of hell bent for leather guys in the prequalifying rounds. The track is NOT a friendly track for a beginner who is aggressive, but is a great introduction to a beginner who is able to think and has some skill, if not expertise, at piloting his vehicle. With this combination of factors, the novice group was extremely light all day. After the noon race, a lot of the advanced guys packed up and left. The advanced guys in the intermediate class moved right back up for the afternoon, and as a result, the PM session was very much a wide open affair for ALL classes. Probably only 8 cars for each of them. By the time we got to 3pm it was pretty much wide open to just go out when you want. By 4pm they brought the starting marshal in and you just pulled out of the pits, watched your rear view mirror and took off when you felt like it. It was AWESOME value and I got a lot of laps in. My tires are all COOKED after four events, and I have to replace them all. Rats. Not a cheapie to get new race rubber. BUT WELL WORTH IT.

I did the article and sent it off to be published on the web, and the video goes out tomorrow morning. So you can watch it all starting probably tomorrow night or Wednesday.

Re: Banked Oval at 135mph

The track was so much fun. Was an all day thing last Friday. We got to do 4 sessions about 20 to 30 mins (10 laps
depending how good we are) each. I took an instructor with me for the first 3 sessions. Sure learned a lot.
glad that I got a good instructor. I was not very comfortable at all on the first session, very slow and was all
over the place on the infield part of the track. On the part that I was most concerned, which was the oval/banking area,
actually was not bad at all...after about 3 laps it became my best part of the whole track. Nothing to learn there
just get the car going really really fast... there is one hairpin, that I could not get it right and I hate this part most.
2nd session was better, starting to hit the infield corners a bit quicker without too much sliding or getting the car out of control.
Getting even faster on the banking, going a little over 100mph up there. By the 3rd session i was hitting over 110,
still having some problem with the hairpin though. Worked really hard with the instructor on this part of the track, but still not getting it.
Decided to go alone on the last session. A bit nervous on the first lap, no one telling me what to do any more. 2nd lap was better,
was going faster also. David with his Mazda RX8 was in front of me. By the 3rd lap I was getting some what comfortable, felt more
confident. Started to catch up to David and even had to slow down a bit behind him. On the 4th lap I decided to pass him.
the best place to pass was on the banking since my car does have more power than his. Red lined 3rd gear, 4th, I got along side of him,
shift to 5th and went by him, by this time I looked at the speedometer and I was doing 125mph. Slow down a bit and turned on the banking,
man, that felt really good. David kept getting further and further behind. Two laps after I passed him, I am going faster still, more confident
in the infield, even the hairpin did not scare me as much any more. Well the next lap I hit that hairpin way too fast, I was all over the place,
went on the grass, slid to the left, tried to fix it, slid to the right, turned the wheel the other way and ended up went into a violent 360.
Never was scared like that in my life! I really thought I was going to flip over. David saw the whole thing, he said smoke from my tires
was every where. I stopped, walked around the car, checked every corners, car looked good, not a signed that it was abused a little.
Started her up and finished the session.

It was a worth while day, time and money well spent. As you can tell I am still excited about it.....

Re: Banked Oval at 135mph

Great to see yourself having a ball out there too Bo ... and learning while doing it. The infield section of Cali Speedway makes for an ideal place to explore the limits of one's car safely. The high banked oval section is another ball game, however, and should always be treated with respect.

Don't feel embarrassed to have put your car off the course. In my honest opinion it is a good thing for the novice drivers to experience lost of control and spin-outs, provided the conditions are ideal and clear of traffic while on the track. I can teach and show you what it looks and feels like to be losing control all day long, but until you experience it first hand behind the wheel, you haven't fully understood as well as learned yet. That is ...

1. Getting over the initial fear of spin-outs and/or losing control in general.
Do it often enough, you will see that it's actually not as scary as it seems. This is what builds confidence (aka *****) on the track and the very fundamental of being a fast driver.

2. You will eventually learn to read your car ...
Subtle feedbacks, whether tactile or auditory, that you weren't aware of in the past provide valuable insights to what your car's doing at the moment. With enough practice, you'll be able to sort her out should she start to get away from you again.

Looks like I lost a great opportunity to play with you guys We'll save it for the next one.

Cheers,

Clint (THX723)

Re: Banked Oval at 135mph

Bo was great. He got a huge amount out of the experience, much more I think than I did on my first time out, and had a great time. The conditions were really excellent and he approached it very intelligently and methodically, which is the way to do it.

Yeah, 125mph on the oval is for the first time out just a wee bit on the quick side. I will be posting up some pics later this evening on the g-owners site of the Viper that took a lip lock on the wall, which is a sobering view of what happens when things go wrong and you do a great job of controlling it...ie, this was the best outcome that could be expected!

sounds like you guys had fun!

1- speed ventures is awesome! always a good crowd. aaron is always entertaining... and the regulars with SV are great also.

2- has anyone run california speedway with only the infield course? i have run this layout twice (since they opened), and i found it terribly boring. like another member said, it is GREAT to explore the limits of your car. i'm surprised they don't have more drifting events here.

is the layout with the bank a bit more of a challenge?


3- ed, what alignment specs are you running? (mainly camber and toe). i've discovered that my g35 with a 1.5"-2" drop runs about 1.6 degrees front, 1.3 degrees rear. i'm debating camber arms since a 2.0 degree front is more then fine for me (i still street drive the car sometimes)
