November 20th and 21st I participated on a track day event at Buttonwillow Raceway Park, Buttonwillow California. With "D" minus 5, I checked the weather and and 70% chance of rain.......

I was not even thinking about but John From JEB Performance Tunning called me. A Nissan/Infiniti Specialist in Hollywood California. And said "Hey how about your intakes, are you getting the hydroshield for your cold air intakes for this weekend?" And it hit me, I removed the cover on my bumper exposing air filters to the environment. John said "I have couple of them here, so pick them up for $18 each". I drove there immediately. And picked them up. John also recommended since engine might take in water if you pass through a pot hole. Splashing lot of water into the intake systems. Gave me for free 2 1/2" clear box tapes. Just in case rain was severe.

On my drive to Buttonwillow Race way, over passing the mountains rains were severe. And As I was descending I noticed roughness on my engine. Than weather cleared, and roughness went away.

Throughout entire first through third session rain was pouring, and midway through the second session the engine started to threaten to shut down. And Rev would not go passed 3200 RPM. I was not sure if engine was going into self-protect mode, or there is actually something wrong with the engine due to the fact even with Hydroshield, my engine was taking in water. Than it hit me I have 2 1/2" clear box tapes from JOHN. I Taped bumper making as water tight as possible. KEPT my engine running for 30 minutes and everything back to normal.

Now my runs thought the day. With no sign of rain going away. My G was going all over the track. With spins here and there, I normally run on dry 2 min 14.6 seconds. I really wanted to brake my personal record. So I made some additional mods on my car. Other than Injen cold air intakes, HKS Power Exhaust, deleted my cats, updated ecu from 08's to 10's from a local dealership, Volk TE, KW V-3 which I run one click minus full hard.

Additional mods I made for the November 20-21, 2010. Where Eibach sway bars both front and rear, and GTSpec Towers, and Nitto NT05's for rears only Which I think made worse for the raining conditions.

Luckily by 3:00pm sun was making its way through, and to my surprise by the end of the day I broke my personal best by almost a second. 2:13.626, I could not believe.

I think due to the fact that I played out on rain all day, made me better driver. And when sun came through my Sways and GTSpecs came back with a vengeance.

I think with perseverance and little help from honest and hard working people around. You can overcome obstacles. I feel great, and thank you JEB Performance Tunning for everything you have done. Your 2 1/2" clear tapes saved my day.

I now appreciate all areas of motorsports. From Nascar to Indy to F1. Those guys are overcoming obstacles on a daily basis. Which I think is one of most understated, but joy of motorsports.

I will post pictures and videos after editing them. And will be sharing more of the Sunday's event when I broke 10 second barrier for the first time. I posted best time lap of 2 minute and 9.78 seconds. COMING SOON.........

wow . . . goog job . . .

but I did not know that having a 2010 ecu update would improve ur car's power.

which dealer did you get this done at and what did you tell them to make the update?

joo030879

It will not give you more power, but take off some glitches from previous version. I think jung Woo can not tell you which dealer, since authorized dealers will not perform ecu updates. And there maybe issue with warranty.

Is your G 6mt or AT?
How did it feel switching to the TEs compared to the stock wheels? Did you compare lap times?

jungwoo0622

I did not compare lap time. But after TE's car felt much better, and because of wider wheel base I was able to fit bigger tires. All of us at the track we try to have our tires farthest apart from one another. Some drivers I know have the tires stick out beyond the fender line, with Tein racing coils. Who does about 2:00 flat on buttonwillow raceway with S2K.

So other than weight issues having wider wheels will help car's performance.

Jung drives 6mt.

So can you confirm before and after. Eibach Sway Bars, GTSpect Tower Bars, and Nittos for your rear. The time difference is one whole second?

jungwoo0622

I would say Eibach Sway Bars played a big part in it. However Saturdays time was on a wet track. Similar dry conditions came on Sunday. And I was able to post 2:9.78. So Compared to the time without Sways, Tower, and Nittos. The difference is not only one second but, 4.82 seconds.

I never dreamed with a street tire, heavily equipped G37 could get so close to time posted by Porsche GT3, with sleeks and we all know GT3's are track ready versions of 911's.

iTrader: (3)

Are you getting sleeks for your next event?

jungwoo0622

Yes, John is already working on some deals on 18" rim, and sleek tires for me.

I wussed out and didn't go, only to find out it didn't rain on Sunday at all from Dave.

That and my car wasn't prepped at all and I stayed out till the sun was up on Saturday...

Jungwoo: What do you think a G37 would run at BW13CW? I have it pegged at a 2:07 (stock).

Are you running 245/275 NT05? Also, do you have any lap telemetry? I'm curious to see your speeds through busstop, riverside, and through sunset.

Also, that's an impressive time for the amount of traffic you had to go through =O. You had to have lost at least a few seconds from that...

I know a driver that does 2:00 flat with stock suspension on 255 street tires... on something in the realm of +50 offset. Who do you know that tracks a s2k on SRCs? There's not TOO many... I probably know them

LOL, i noticed ur clear tape work out there and that sucks u had that issue, but it was fun running an that wet track

jungwoo0622

It is a miss fortune to have missed you Last Sunday. Hope you are having fun with car preparations...

Well to assume stock G37 would do 2:07, would be something I would not try especially with my new born baby who is 1 1/2 now. I am not saying it is not doable but to steer Stock G37 on over and under steer alone would be something I would not recommend. We need some kind of assurance, ie. Mechanical Grip. Buttonwillow Raceway is +- 2.9 miles long. You would have to go with average speed of 82 miles per hour to accomplish 2:07. I never tested the limits of a stock G37, but most corners are impossible at 82 or close to 82 miles per hour. My average speed is little over 80 miles per hour with all the modifications I have done. And it is close to the my current limits of G37. As we all know we are + on weight, - on torque, and - racing tires. Unless Santa gives me some turbos for this Christmas, I would not try 2:07

I am running 275 NT05's. Lap telemetry, I have only on my head, maybe it is good idea to do some math. But I don't have too much time for that right now. On riverside which is probably most scary part of the track for me I think is +-85. On BusStop I think +-70. Through Sunset I have bad habit of carrying too much speed than other drivers I think +-61.

No the traffic was not too bad, most drivers on my session were experienced and they would get off line quickly.

Well about the driver you know who does 2:00 flat on stock S2000. I want to meet him. Because only one I know is Pro Driver Charles Nguyen (not in person but on YouTube Video, I subscribe) who does +- 2:03 on a genuine stock CR. On S2K I am referring on a previous post is Kang Woo.

That CR isn't stock, and the tires are mismatched That's Justin's car, which also happens to have an exhaust. Also, Charles Ng does a 2:03 in his own 100% stock car, under summer conditions, and his car isn't really set up for grip...

A 2:01.0 was done about a month ago on stock suspension with a APR GTC-200 and RS3's. This was with several mistakes, and on a short session. Data shows a 2:00.00 is possible without errors, and a sub1:59 is the temperatures were slightly lower.

How's the car balance through Riverside? CR's rear gets loose; the wing is too small and cornering speed is limited by the rear. Sunset always "sounds" like you're going too fast cuz of that patch at the apex....

Are you going to use AD08/RE-11 on the 18's? The more aggressive gearing may help...



Recognise that garage? Kangwoo's neighbor has a S2k too, and the guy 3 garages down has a 600+whp turbo M3...

Once again talking about S2K. Hey Mike can we now talk about our G's instead of your S2K's. Please......

If I had a choice which car to take to the track. I would choose S2K, but I enjoy my stylish, with enough room for my children, Room for mine and a friends golf bags at the back, Track-able Infiniti G37S.
