Default My in car video footage from Infineon 10/23 & 10/24 (aka Sears Point)

Finally got my video up of last weekends event (10/23 and 10/24) at Infineon Raceway (Sonoma CA, aka Sears Point). One wet day, one dry day. Running the extended turn 7 configuration.

My quote of the day from an EVO owner "I've never seen an STI this fast before".

http://www.gofastpilots.com/infineon_video_102304.htm

Have fun, the video size is large so broadband downloads are recommended.

Finally got rid of the understeer without having to resort to bigger sway bars.

Nice video and great driving.

Where is your camera and microphone located? There is very little wind noise.

Talk about disappointing! I just downloaded video 4 from Day 1, which was shown on your site as 123MB, but it came across as only 19.1MB. I started to play it, and the total time on Media Player showed 16:47 or something like that, but then it stopped after just a couple minutes, about the time you guys were finishing your warm up lap.

I'm downloading clip 1 from Day 2 now, it shows 106MB.

Are your tires rubbing in some of those videos?

I was just gonna ask the same thing, CMJ. I just watched the Day 2 clip 1 video, and on the hard turns there's definitely something that sounds like tire rub.

As for the clip, awesome. You were definitely flyin', Rob. That yellow RX-7 put up a good fight, but it looked like he was trying to hard to keep you behind him and eventually made a mistake. It was cool to see how early you could put down the power coming out of the corners, which really allowed you to pick up ground.

Pat

PS - What's the white open-wheeled car at the 5min point of the day 2 1st clip? Looks like some sort of vintage racer (replica?) as you blow by.

PPS - So what was your understeer fix?

Yes got some tire rub, enough so that I need to do something about it -- grind some melt & raise the ride height a tad (may 1/8th).

RX7 had some good grunt don't know his HP/weight ratio.

EVO had some grunt too, EVO was well modified and putting down about the same HP as I am (275-285 WHP). The black modified Z06 has some grunt too. The Lotus 7's should have been very fast at 200+ WHP and 1300 lbs.

Sat wet Session 2 a really bad driver in another blue STI hit a Lotus 7 (can can see him and his black EVO buddy spin) -- he showed no remorse nor attempt to settle damages with the Lotus 7 driver so he was black listed and tossed out of NASA -- you never want to be black listed cause that list circulates for ALL racing organizations. The only way that STI driver will see another track is if he gets dady to build him one (which might happen as this kid had too much charity money and not enough brains).

I mounted the camera on the dash cowl this time around and the mic is on the dash also.

Understeer fix was run 1/8 - 3/16 front toe out and 1/16 rear toe in. But the biggest fix was me discovering just how much toe changes when camber changes on these STI's -- holly cow!! Going from -1.2 camber to -3.5 camber changed the toe from 3/16 out to 7/8th out -- that EXPLAINS alot of my issues including buring thru new Hoosiers in one day at Thunderhill.

Rob, John Felstead in the "Video lap of the Nurburgring, STi5 TypeRA Style" thread mentioned shimming the steering rack to get rid of the bump steer. The thread was recently moved and is not accessible this evening.

You car has a lot of grunt!

Pat, that white car looked like a Thunder Roadster, from the same folks who make Legends cars.

Bumpsteer wasn't a big problem, except a couple of times I got hooked on the curbing. But I'd be interested to see what/how he shimes the steering rack.

On Vishnu's dyno I'm only making 275, certainly well below what many others have posted -- but that is a safe (road racing worthy) tune. I do have the intercooler water spray triggered by the XEDE, and I go thru about 1-2 gallons of water per 20 min session (with 100 octane race gas).

Forgot to put on my website, but I'm also running 1/8th rake. Cross weight (driver to RR) is 50.3%.

Next stop for me is Laguna Seca Nov 30th.

Rob.

P.S. Apparently I was putting out some good flames, just waiting on my buddy to post some of his footage so I can see what my car looks like from his point of view.

Ugh... 40k/sec on a 92meg file. These videos need some real compression.

Hi Rob,

I had the same problem as someone else with a partial download on one of the vids. I successfully downloaded and viewed the last one (Sun. Session 4). Thanks for sharing!

I, too, had a question about tire rub - or SOME kind of noise that was evident primarily in left turns. I also noticed, for lack of a better description, the engine racing between upshifts - as if the clutch was in before you were off the throttle. Is this normal? Is it a lighter flywheel? Just curious.

Mike - going to Homestead on Sunday and can't wait!!

The video's are compressed? The native AVI format is 3.3GB file size, these are 100MB or so. I don't like to compress any lower than what I currently do as it looses too much quality IMHO.

I'm running stock intercooler, BOV, etc. etc. so the engine rpm increase during shifts is most likely the XEDE and ECU coming to a mutual compromise in what to do with the pressure -- either that or the throttle by wire Subaru system got confused. Clutch/flywheel/drive shaft are all stock.

Yes, there appears to be a problem with Sat Session 4 which I will checkout this weekend and update as needed.

John, I'll look for your thread.

Rob.

I'm not getting around 150k/sec... I blame it on johnfelstad for tieing up the server.

what made you choose the Toda double adjustables? I see that they are $4000 for a set. At that price I think you can get shocks like penskes, jrz already.

Rob, I might be misunderstanding you but bump steer is not just about hitting curbing, it is about toe change any time the suspension extends or compresses.

John's thread is back up. He talks about his car setup including bump steer in http://forums.nasioc.com/forums/show...4&postcount=22 and http://forums.nasioc.com/forums/show...&postcount=417

Penske doesn't make a for a good dual purpose shock (i.e. street & track). Penske is a great shock, but the TODA is just a good all round street and track and dirt shock -- now if I could just get someone to translate the Japanese so I know how to adjust them -- right now it is guess work as to which way to turn the adjusters -- make adjustment and go out and see how it feels. I think I've guessed the adjustments but not really 100% sure.

Plus TODA tossed in a slew of extra springs at various rates, 10K, 9K, 8K (4), 7K, 5K.

No experience with JRZ.

I took a close look at Endless also.

TODA are very responsive, just takes some time to get there stuff.

I know what bumpsteer is, hitting curbing is where it really only becomes an issue for me (see exit to T6) -- it would be nice to remove some, but bumpsteer will always happen to any car to some degree (at least Subaru's anyway). But thank you for the link, that was very informative on the steering rack and probably something I will do soon as it is a very simple fix.

Interesting to note John's front toe settings toe-in ?? That certainly is contrary to all the information I've gathered on suspension settings for production based street cars -- I may give it a try as AWD and Subaru's are new to me. Good information, thank you!

Rob.

Rob, went back and reread your 7/8 toe out thing and just now realized you weren't talking about bump steer. My mistake.

Thanks for posting your videos.

The link to John's complete thread is http://forums.nasioc.com/forums/showthread.php?t=242511. For background he is using his daily driver and running laps at the Nurburgring, not on race tires. There are 29 pages in the thread but hidden in a couple of places (mentioned above) are his setup and views on it. There are also a few videos.

Good luck on figuring out those shock settings.

Watched a few of these last night and you are quite the driver. You make the other drivers look terrible at the exit of the big double apex turn. Thanks for posting these, very fun to watch.
