video setup
- sony dcr-hc32 minidv camcorder (to record)
- hoyttech lipstick camera
- external mic
- chasecam triple suction cup mount
minidv camcorder- i use a sony dcr-hc32 camcorder. touchscreen, remote.. it was relatively cheap and has worked flawlessly. they also sell solid state devices to record to which may be easier to deal with. i just never looked into it since i wanted the flexibilty have using the camcorder for other applications.
lipstick cam- i got mine from hoyttech.com (same sony camera that chasecam sells at a better price). It's a 580 line camera.. here's the direct link: click me
external mic (stereo)- click me
that's it.. simple and easy to use. now to figure out how to get a PIP footwell shot.. maybe something we'll work on for '08. a little creativity with ductape may be the answer!
hope this helps,

sti for sale!
i'm sad to say the time has come. i will probably regret this, but i'm putting the sti up for sale and i want to see it go to a good home.
you've seen the pictures, you've seen the video.. here are the details:
2005 STi. 42k miles currently on the odo.
i had to order this car from japan (an agonizing wait) since white is a highly desirable color. engine was properly broken-in. mobil 1 synthetic oil and factory filters used every 3k miles after. services done at dealer(northcoast subaru in glen cove, ny). they know me well!
i've spent a lot of time dialing in the handling of this car and the results show. the front grip and turn-in is awesome. great steady state balance, kickass in the slaloms. you can throttle steer it, pitch it into corners, drift it... it handles beautifully. this car is consistently at the top in the right hands. i will supply shock and tire pressure settings to the buyer if you're an autoxer.
suspension:
tein flex coilovers. 10kg/mm springs all around.
whiteline camber bolts.
whiteline 27/29mm front sway bar
whiteline adjustable rear sway bar.
kartboy endlinks front and rear
brakes:
goodridge stainless steel lines
ate super blue fluid
hawk hps brake pads all around
front brake rotors replaced recently.
power:
helix catted downpipe
spt catback
cobb accessport with custom maps. pdx stage 2 + 100 octane STU map.
this car makes sick power with either map.
3 sets of wheels:
stock silver bbs unmounted (also have re070 with decent tread left unmounted)
17x9 5zigen fno1rc (black with polished lip) with end of life advan neovas.
17x8 rota boost (gunmetal) with nokian WR all-season snow rated tires- badass in snow. great in dry.
interior:
factory short shift option
compass/autodimming mirror
factory lamco boost gauge
recaro speed driver's seat
jazzy engineering ipod adaptor
anti-theft security enhancements(i'll explain to buyer)
exterior:
rally armor mudflaps
holunfie stickers (+10hp)
extras:
tein 8kg/mm springs (pair)
strano 32mm front bar
factory rear sway bar
stock driver's seat
stock suspension
couple sets of track pads. ferodo ds3000, hawk ht-10
serious buyers only please. i guarantee that you will have a shit-eating grin on your face after a test drive. there is nothing to touch on this car to make it competitive for STU. if you want more comfort over the winter, put in the stock suspension like i have. the teins have never seen snow/salt.
kbb value on this car is $23k stock. i will let this go for $24k FIRM with ALL of the goodies. i believe that is more than fair. shoot me an email if you're interested. dancheung@gmail.com
PLEASE- no flakers or tire kickers.. serious buyers only!
what's next for me? most likely an s2k while i patiently wait for used exige prices to fall. rwd is calling me.

Grant Sheffield Winchester
Here's the man!
This is our favorite part, nothing like taking your children home.
Gabe was a huge help getting Grant out of his car seat.
So everyone is now home and adjusting to Grant's presence. Mommy is recovering well, Grant is definitely getting his poop on and Gabe is still a 2 yr old if you know what I mean.

who doesn't love Street Mod??
The Sias car is still badass. Mark has NO aero. Almost every car lifts the inside rear. I would think more drivers would be tighter to some of the cones, maybe it's the viewpoint or the fact that I never saw the actual course. Oh, and the fabulous dorifto is Tage Evanson in an EX Showcase car.

moldy bread
So Dan has been telling me that our readers would like to see some new content. I get it, I think the page has been stale myself.
As for the lack of content I think Dan has been cycling quite a bit and actually has a girlfriend. Uh-oh, is he gonna fall off? I've been busy as hell with the new job and Diane is getting ready to pop with boy #2. :)
Here's a peek into some new topics I'd like to write about.
I know Charith still wants to see my home alignment how-to, maybe we'll get his car in the garage for pics.
I've also been on the hunt for some old results and pics from back in '99, '00 and '01. These were very much the formative years of what have turned out to be the long lasting friendships and rivalries of holunfie. I think it will be nice to show where we came from, cause it sure as hell wasn't 300+ hp AWD rally cars. Here's a sneak peek...icky body roll, stock tires and loaner helmets!...yuck

Congrats go out to Mark Daddio for collecting the ProSolo and Solo Championships (Junior and Strano did too!). I don't know any of the real stories but watching results I was very impressed with the Carris'. Chris' push on his last runs to get up to 2nd at the Finale was total perserverance. Chris also got to knock out Mark 1st round in the Challenge! Sorry Mark, it's just more fun rooting for the underdog! Diana's 3rd place at Nats was only .25 sec out of 1st and must have been heart breaking after holding 1st place on day 1. That's the kind of loss that makes the fire inside burn hot, I've got a feeling this will only push you more Diana! Corey did some ass kicking at the Pro and then had an eye opener at Nats, gonna be a long winter of setup planning for you!

NNJR - 9/22
Yesterday's autox was NNJR's last points event for the season. The track layout was a Perry special, with a loop-around shortly after the start. Walking the course was definitely key, since there was a tricky right hand turn after the double cone gate, which I missed on my first run. The first heat was almost complete when the clouds started to move in. Then came the torrential downpour! It was decided that we were going to take a half hour break before the next heat. Luckily the rain slowed down before too long, and the second heat commenced. There was a ton of standing water, so traction was at a minimum. The average autocrosser doesn’t have a ton of experience driving on wet pavement and things were a little tricky. By the third heat, the water started to displace, but a ton of cars were still spinning out (Twice me included!). During last heat, the pavement really started to dry up as the sun shined, and many cars were posting times matching/beating the first heat’s runs. All in all, it was a fun day. I really learned the limits of my car in the rain, as did most people!

nyr
i took tricky for a ride on this one.. 51.7 +1 i think.
pax shook out with jay, gj, me, and kevin taking the top four spots in that order.
with the autox season winding down and no topeka for me (good friends' wedding next weekend), i've turned my focus towards training for the nyc ms bike tour. as if a flat 100 miles weren't bad enough, this ride includes a lap around nyc, a bomber run through the lincoln tunnel into jersey(sans cars), a brutal climb up the palisades to rockland county (with some sick elevation changes along the way), then back across the gwb to the start/finish on the west side.
this will be my 2nd year doing the century (100 miles) with the nyc ms bike tour. they say a century is a biker's equivalent to running a marathon. of course the physical pain is killer but i think the mental pain is even worse! i've been training hard to beat my 6hr 30min time of last year. after today's event, i went for a quick 10 mile sprint... i've logged 740 miles in the saddle since this time last year!
make a difference... help fight multiple sclerosis! any donations to support me on my ride to support MS would be greatly appreciated.. http://msnyc.kintera.org
or better yet, sign up and join me! i could use a training partner that isn't a pussy (you know who you are!). there are 30 and 60 mile route options for the less crazy..

p.s. keep your eyes out for a topeka report from carris and valera... good luck guys!

Rev It Up- Washington, DC- Story: Part 2
I had a prior commitment to this school before the Rev It Up schedule came out, and I'm not one to bail on events, especially a Teen School, so no matter how much I really wanted to be in DC and watch the final day of the Rev It Up unfold. I just couldn't be there for it.
Of course during the day, I'm telling everyone what happened the night before. And as usual no one believe it, neither did I at the time, I still thought I was asleep dreaming it.
Later on in the day, I received a phone call from Demetri inviting me to a block party that night at Thom's house. At the time I had nothing planned, so after the School, I drove over there to check it out.
The block party was great, the entire street was closed down, kids were running everywhere, toys were everywhere, food was everywhere. They even had a DJ there playing music and games for the kids, then later in the night a band came in and played for a while.
Ok, to get to the interesting part of the story now. Somewhere around 9 pm, I received a phone call from Rogers Simon, who was at the Rev It Up, calling to give me an update as to who's on the leader board in the Cobalts. I knew who was planning to be there already, and had an idea who was going to be on that list as he started reading names and scores. You name it, the Who's Who of Autocrossing was there: Daddio, Salerno, Strano, King, Johnson, Baker.... etc.... etc..., I could keep going. With that amount of great drivers there, all of them multiple National Champions. Each one of them is more than capable of doing what I did. So of course I started to get nervous.
Somewhere around 9:30 Rogers called me again to give me an update and let me know what the Pro Driver Index was. A few minutes later my phone rings again, this time its Matt Arnold who was there giving me an update.
Next thing you know, I go inside the house, its so loud outside with all the people and music from the block party that I can't hear the phone. I'm pacing around the house all nervous, (probably wore through the carpets) holding on to the house phone in my left hand with Rogers listening to the event as its happening, then in my right hand, I have Matt on my cell phone listening to what's going on from his side. Demetri and Thom are there both laughing at me, holding on to 2 phones pacing around the house, I wound up locking myself in the kitchen for a while just to get some peace and quiet so I could listen. Demetri came in a little while later and grabbed my cell phone and started talking to Matt.
So we're all there I think they are about as nervous as I am, as we're listening to what's going on there. One run after another, hearing Caroline in the background calling off drivers names and times. No one is getting close.
We're now onto second runs in the Corvette's.
At this point its getting pretty late and the block party is starting to wind down, and people are leaving to go home. Then Demetri starts bugging me about leaving. I'm like, no way dude, I'm not leaving till I hear the end of this.
I wound up having to lock myself in the kitchen again after pacing around the house for a while so I could hear the end of it. A few minutes later, they gave in and wanted to hear the end of it also, so we're all sitting there in the kitchen.
Its getting down to the final few drivers, all of a sudden, they have a timer issue. The entire house went quiet. We're listening to see who will be getting a rerun. Of all people who was getting a rerun was Daddio. None of use could believe he was getting a rerun. The event keeps running and the reruns will be done at the end. Then it comes down to Daddio getting his rerun. Caroline is calling out his run, we're listening as its happening. He comes into the finish, Denied! Wow! Daddio didn't beat me.
Here I am thinking I've just won! Then all of a sudden a protest about a car problem came up, and I hear they are about to give Ian Baker a rerun for something. Ian gets his rerun, we're listening as Caroline is calling out the run. He comes across the finish, Denied.
Then in the background I hear Caroline call out my name as the new 2007 National Champion, its official I won. Rogers and Matt who I was on the phone with both congratulated me, then I thanked them for keeping me on the phone to listen in.
I hung up the phone with them, then a couple minutes later. My cell phone rings again, its Dan, the Media Rep from the Rev It Up program. "Congratulations GJ You are now the new 2007 Chevrolet Rev It Up National Champion" we talked for a while and asked me a bunch of questions for the press release.
At the same time, we're walking outside to leave and go home and I believe it was Demetri who yelled to everyone at the block party that I won the car. Everyone on the block cheered for me and congratulated me.
What a Crazy Night!
At that point I'm so exhausted from the day, but so excited that I won, I didn't know what to do. On the way home, I made like 50 phone calls to start letting everyone know. I arrived home and couldn't sleep from the excitement. I think at some point I passed out, but don't remember.
Rogers Simon recorded all of my runs from Friday and he gave me a DVD of it last week, so I'm hoping to post the videos of my runs soon.

Rev It Up- Washington, DC: Story by G. J. Dixon
I drove down there mid morning on Friday for my late afternoon runs. Since I got there so early, I was able to get the first parking spot out front. This also game me some time to get a couple hours of sleep before the gates opened.
Once the gates opened, I registered, then we all have to take a class room session before we are allowed to participate in any of the driving activities. Once that was completed, it was off to get some seat time on the practice course in the Cobalts. This year it was different and we were allowed to take as many runs as we wanted. In the previous years we were only allowed to take 2 practice runs.
Off to the Comptition Course for my Runs in the Chevy Cobalts.
My first run in the Cobalt was 0.2 off the Pro Driver scoring me with a 700. The Pro Drivers time on the course is worth 1000 points. Everyone's time is indexed off the Pro's time, which is about as fair as it gets with changing weather conditions and different course layouts around the country at each location. This was good enough to put me at the top of the leader board for the day. Upon getting out of the car, Caroline (Rev It Up Announcer) called me over and interview me for a few minutes. She asked about NY, coming down to DC, and about the course. Next came my second run in the Cobalt. Unfortunately, it was dirty with 1 cone, but my time was 0.014 off the Pro Drivers time. I believe it would have been a score of 950 or in that area if it was clean, which would have been the highest score ever achieved in the Cobalts.
After my first 2 runs in the Cobalts, I had a feeling something was going to happen that night. I didn't know what, but I was really enjoying the course that was layed out. Unlike the NY event, this course was more like a typical autocross and was open in a few locations so you had a choice of racing lines. Later in the evening, Brian Priebe knocked me to second place in the Cobalts, but my first score was still good enough to get into the Shootout in the Corvettes.
Before the Shootout, a bunch of us all went over to get some practice in the Corvettes. Unfortunatley, the practice course was not timed as it has been in years past, but it was still a great opportunity to check the cars out and get a basic idea of how they drive.
Time for the Shootout!
My first run in in the Corvette was (39.0) about 0.2 off the Pro Drivers time (38.8), scoring me an 819, which was 7 points shy of Chris Ramey's National Lead of 826 points. I knew going into my second run that there was more time out on the course, and that it would be a matter of me keeping it clean not hitting any cones.
On the second run, I made it through the first 3/4 of the course really fast, and I knew it was faster than my previous run. The last 1/4 of the course was a very tight technical section, which I knew I had to stay away from all the cones. I got behind a little in one section which caused me to slow down more then I wanted to for the next set of corners. I made it around the last corner and came into the finish clean.
A few seconds later I heard Caroline (Rev It Up Announcer) screaming into the microphone, and I heard the crowd scream. At that time I was too far away, and with the helmet on, I couldn't hear anything. I had guessed that I took over the National Lead. As I'm rolling back into the grid area, everyone is giving me the thumbs up and clapping. I still can't hear what is being said, until I made it around the final corner, looked at the score board and realized I had actually beaten the Pro's Time. I then screamed in the car and started honking the car horn. I had turned a 38.5 which beat the Pro's time (38.8) by about 0.3 which gave me a score of 1197 points.
Upon getting out of the car, all the Rev It Up Officials came over and congratulated me. Then I was interviewed again by Caroline, received a bag full of goodies and got a few pictures in with the NOS Models.
Once everything had concluded, and I went to go home, I walked out to the parking lot to find that someone put a "For Sale" sign on my car. I guess someone knew it was my car and didn't think I'd be needing it after that.
I'll tell Part 2 of the story later, about what happened while I was waiting for the Saturday Event to conclude.

wrx vs evo
as we always enjoy watching... kev and jay battled it out run for run. jay edged out kev for the class win. but kev kept his run clean and took down jay in the shootout! i'd call that even.
kev was up against daddio for fastest evo.. and as expected, it wasn't really a fair fight. under pressure, kev did pull out a sick run though. not quite quick enough to take down mark but pretty damn close on one of the two runs.
the carris' were in their usual form with chris, me, and diana finishing in that respective order in our class. it was tough going up raw-time against chris in his AS car but we were pretty close. great driving guys.. good luck at nationals!
chris decided to preserve the car and loaded it back up on the trailer after the class competition ended. that left me to eventually fend for myself against daddio in the shootout. 2 runs to take down the other subarus, then i was faced with a raw time battle with the alien. stu car vs daddio in all-out SM mode. can you say holunspanked?
for comparison pax-wise, i believe the order came down to mark, me, jay, kev, and chris taking the top 5 spots. holunfie domination. what we like to see!
we all had a great time! huge thanks to perry, ernie, and all the volunteers that put on this event for us!

finger lakes pro vid
here's my best run earning enough contingency to cover the weekend's expenses and then some!
dan
back at it
what better way to jump back in than with an evolution challenge school! if you haven't done an evo school... you should! tons of seat time, top notch instruction, and almost guaranteed improvement to your game. i spent most of my time with ron bistrais, a kickass F-Stock driver. we worked together on figuring out the areas i needed to work on, and took run after run after run. i was working the car so hard, the power steering was actually cutting out since the fluid was aerating! try driving a steering intensive course over and over with no power steering! it was brutal.
when it came time to 'challenge' our instructors, i was able to beat out ron by a tenth. pat salerno was itching to give it a go, so he took a few runs and was able to beat me by a tenth. we didn't want to eat into the other students times so i waited til the fun runs to see what i could pull out.. took me 1 run to warm back up and on the 2nd, i was able to find 2 tenths to beat them both. the school worked! thanks guys.
today, we went to nassau coliseum and it was good to be back with the crew. jay represented by winning BSP, top pax, and FTD!
i was close.. here's the vid of my fast run with a time (48.7) that was good enough to win pax had i not coned it.
you can see i had lost some time with the drift in the turnaround after the slalom.. i had the opportunity to clean it up on my final run, but decided to have a little fun. adil and i swapped cars for our last runs to change it up.
i have to give a huge thanks to mike choi for letting me get behind the wheel of the exige s for its debut event.. what a beautiful car! awesome power, changes direction on a dime, super quick steering rack.. what more can you ask for?
sti for sale! anyone interested?
