A rough sketch of the track I will be running. Finally a couple of my friends are going! EK Civic, RSX, Sunfire, and of course.. the usual me (celica), my brother -MRS, and Corolla

The Corolla, Sunfire, and Civic will all be in the same class (STS)
Me.. as usual.. the same class as them Cooper S

Im building a in car camera mount right now. Hopefully I will have an in car and another video from the outside.

Its going to really hot. And theres thought of running nitrogen in my tires (they stay more constant with pressure) I just have to see till then

I deff like that corse, I'm not a huge fan of long slolums I perfer some straights mixed in, but most the corses I race are covered in slolums.

the coopers S's usualy do pretty good, gana be tought comp, same with miatas though. Good Luck! I would not worry to much about the civics or sunfires.

my last race had me up against an evo 8, evo 9, 350z, maxima, bmw 325 (i think 325,) civic si, and some acura. I did not do so good but what was cool was the diff between 3rd and 8th place was just under 1 sec, there were 12 cars in my group. I got 8th (i'll scan my corse map if you wana see it.)

you do much better than me.. in this event theres about 12 Cooper S all in my class..

The sunfire is going to be cake.. o.O the civic not sure.. its their first event.. and this is my third, but first time in this area.

Only thing im worried is the scribble on the left.. its a big puddle about 5x5x3.. also known as Giligans Island

[creis]

lol nice water makes if fun and evens up the comp, just coast though it you'll be fine, I would not even avoid it, if its in you path just skip on though, but thats me (probably better of going around if your not sure)

the civics are questionable, usualy there not the best, like resonably fixed up motors but cheapo susp. but there are a few, like my last race, out of no were that si took first, it was a total sleeper, was beat and sounded like rice but it deff had something that kept it in control.

[jdg371]

well we have a H22 Civic, Supercharged Accord. their quick o.O

we do have a jdm civic that claims 160whp, quite sad.. lol I beat by 3 seconds in the last events

In this event.. we have "fun runs" 3 runs for 5 bux.. im doing 2 sets lol

Finally made my Cam Bar.. I just need to put the cam and bar together rofl!
(Its going to be used in a Corolla and my Celica)

[jdg371]

w00t! Bar Cam is funtional! still needs tweaking but the rough part is done!.. Im uploading a vid right now.. (only 86% atm) at youtube.. its a 2:31 vid.. of me driving lol.. (54megs)

And here it is..

holy hell, send me the video and i'll greatly reduce its size. hit me up on AIM

[jdg371]

it was just a crap test vid lol..

I will need to reduce my future vids.. enlighten me how

[bloodrain]

the 'easiest' way would probably be just use Windows Movie Maker. you could probably get the video down into the 10 meg range. Or if you can get your hands on Dr.Divx you could do it like that. Anywho, with WMM, just click import file, and then click save to computer and pick the settin that fits you best (gotta play with it 2 see how small the file size will be)

[boosted_K2]

cool stuff...


heres a vid of my MR2 autox'n. this event was at Waterford Hills (WHRRI), this was my worst event of the season as i finished 4th in class and 47th/200 overall. I still hold the ES class lead, but its much slimmed down now.

The video is my friend/codriver Alex driving, hes currently 3rd in the standings, and finished 2nd at this particular event.

I havent had a chance to upload my runs yet. Note this is the fastest course we ran this year, lots of 3rd gear time and rev limiter bouncing.

the mount is the chasecam extension mount, the camera is a Canon SD630 running at 30FPS... obviously any quality the video had was killed by the youtube compression.

understeer > me

when you understeer that bad turn the wheel LESS, not more and let off the gas, its a really hard thing to do, but your car will actually turn more with less input.

[jdg371]

turn less with no gas then? Also my friend who autox his 01 rolla said do all your braking before a turn.. does that go together?

[boosted_K2]

yes, it all deals with the same concept.

the short version:
your tires have a finite ammount of grip they can deliver (100% of available grip)

when you start asking them to do things (brake, turn, accelerate) they use a percentage of that available grip. in real basic novice concept you want to focus all 100% of the available grip on single tasks at a given time... you hit the braking zone... you want to use 100% of the tires to get you to slow down... you get into the turn, and you want to use 100% of the available grip to turn the vehicle.

when you get too deep and are using 80% of the available grip to get the car to slow down, THEN you try to use say 50% of the grip to get the car to turn... you are now at 130% available tire grip. voila! massive understeer. the concept of less steering + less throttle/brake input = more turning relies on the fact that you are now using less a percentage to turn, so as you unwind the wheel, the tire will start to get back closer to 100% and start to grip and make you actually turn again.

again this is a very basic/novice concept but works WONDERS for getting used to understeer/oversteer and braking... the other major contributor to this is slip angle, which is a little more advanced of a concept but deals with the same principals.

[boosted_K2]

when you find yourself overshooting a turn, get the wheel back fairly straight and lessin the steering, once you feel grip return, back off the brake and turn in more, next time in that turn get the braking done sooner or do more of it.

[jdg371]

Any suggestions in this track?



Im running it in 2 weeks they say its a reverse of a 70sec track

[creis]

^ dang you get some good tracks. only advice i can say about it is take the corners wide at first then cut in sharp to line up the next obstical, and yeah break before the turn then coast and hit the gas pulling out of it, the fwd has an advantage because you can pull hard out of a turn and keep it in control, were rwd has a much harder time not pulling to hard and swinging the back end around a bit.

that is some serious body roll but you did not do bad at all. (dont have sound on my work pc but I'll hear the sqweelin when i get home.)

a few very shot videos of me racing.

not too bad.. I got 53 out of 75 with PAX times. Im raising the camera upsome so you can see the cones as I go through em..

heres a vid of my friends Corolla
STS Corolla > GS Celica

http://www.youtube.com/watch?v=yQUmpNwo0m4 same cam mount.. yet it looks better lol

[creis]

yeah if the camera was a little higher and amed down just a bit, it would be sweet.
