1st time tracking my STi on a road course, worry about oil starvation part 1

1st time tracking my STi on a road course, worry about oil starvation
Going to the track this Saturday, should I worry? :confused:

I don't know the details of the stock STi oil pan, but I am sure the factory pan don't have any oil baffle plate in it.

I will be running on stock tires (Potenza RE070) and stock suspension.

For you people that have track your STi already, have you guys encounter any problem as far as oil pick up during hard corning goes? The track I am going to is 2.2 miles long, 10 turns, medium speed (up to 110 mph in the straight).

I just know the fuel pick up in the gas tank is not so good, because some people (including myself) have experienced stalling the car during corning when the tank is low.

Thanks ahead ;)

i tracked my sti in stock fourm with 100 oct
it ran great no prodlems just too many evos

elgorey 12-11-2003 08:38 AM

given that I never had any oil pickup or fuel starvation problems on my WRX, I seriously doubt an STi would have them.
You should be fine, just make sure the oil is nice and topped off.

yeah i had no problems wit hmy 02wrx on the track. i havnt done any trackdays with my STi yet. but i did do a autox and it was great.

I ran my car at Mid-Ohio for a whole weekend. Never had any oil problems.

As far as fuel goes thou....make sure you start with a full tank. After 25 mins of hard driving I was at half a tank of gas. DO NOT go lower than a quarter tank of gas on the track. (I never had less than half)

The onlt other problem I had at the track was that these damn M3's kept getting in the way....the just couldn't stand the fact that a Subaru was passing them.

Have a great time! You'll learn about what you and your car can do. Start slowly and work your way up.

Cheers,

You'll be fine, especially the first time at the track. Change the oil before and after and try and rotate the tires. But I think that people who go to the track for the first time should drive underpowered 90hp cars to help learn instead of supercars.... oh well, that's me. :)

No problem with oil starvation with the STi at NHIS running the north oval, where you're in an 80+ MPH corner for about 8 sec. I ran on 94 octane and didn't have any fuel starvation issues, but I don't think I went below 1/4 tank.

I had problems with 5.0 Mustangs getting in the way on the straights.
ANZAC_1915 12-11-2003 10:34 AM

Impreza owners in the UK frequently put in extra oil for track days there. I've never had the problem myself, just make sure your oil is to the full mark before.

Keep a close eye on your tire temp and wear between sessions.
JDM addict 12-11-2003 12:46 PM

Thank you very much for all you guys' advices and sharing your experiences with me ;) I sincerely appreciate it.

Now my mind is at ease to have fun on the track without having to worry about losing the motor around turns :D

This is why an internet forum is so great :)

Hi charles s,

I am going to Spring mountain motorsport park in Pahrump, Navada.

Thank you for the advice ;)

This is not my first time driving at a track, this is the 1st time I am tracking my recently acquired WRX STi. Although I don't have A LOT of track experience, I do have some track time.

I did it the right way, I learned about track driving with my college car, a 180 hp FWD Celica GTS, then I tracked a 290 hp NSX, then a 349 hp AMG C32, then I autocrossed and tracked a 430 hp R34 Skyline GTR. I am pretty confident I can handle the WRX STi at the track. :) I actually have 130 less hp this time, but the car weight 200 lbs less then the GTR.

Sorry, I don't have specific advice for the WRX / STi, the WRX for me gets used a commuter. :D My track monster is a 126hp Mazda Protege, and previously a 103hp Protege. ;)

I see you edited your first post, always try to keep your fuel level above 1/2 tank. I don't think that would be too hard. Maybe it would be a good idea to use some of the 100 octane fuel they have available, but it is usually about $5/gal. I'd do a mix, knowing how some of the STis have had pinging / detonation problems. (I haven't kept up with that lately).

Everybody has given good advice so far.

Overheating a tire could cause it to fail. Not fun if it was to fail in a corner
elgorey 12-11-2003 02:06 PM

No performance tire is going to fail and blowout due to heat.
Especially not the Bridgestones on the STi. They may get greasy and lose a little grip, but will not fail.

[i]maybe[/i] a $20 pepboys special, but Ive even seen those take some major abuse.
elgorey 12-11-2003 02:08 PM

About fuel, Ive had it down to the fuel light and still didnt have any starvation. Usually try to fill it back up before it goes too far below 1/4 though.
WRX 2002 12-11-2003 02:27 PM

Just check your oil after every session, the STi is know to use oil on track days, especially with the 5W30W oil. As the other say I have had fuel starvation at just under half a tank depending on the course.

Change the brake fluid to something better than standard like Motul 600 RBF and you should be good to go.

DonA...............I agree with elgorey there, I don't think tire fail due to heat. I know they get greasy and don't grip as good........

I only heard of tire failing because they are in extremely high speed (160~200 mph) for a long period of time. Maybe that is due to overheating? ummm....... :confused:

red5001 12-11-2003 06:29 PM

I didn't have a problem with oil starvation when I tracked the car at Summit Point, WV. The car ran great. I did change brake fluid to ATE Super Blue and I used Panther Plus brake pads. Other then that the car was stock and didn't have a problem. Hope that helps.

The Oil pan of all Imprezas are fitted with baffles, it's actually a very good design for a production car. You also have a windage tray as standard to stop oil from hitting the crank.

Check the oil level after each run and dont foget to use the hot fill marker on the dipstick as your reference, thats the notch in the side of the dipstic.

Fuel pickup on the STi is very good, it is fitted as standard with the same assembly as used on the Spec C, which has an anti-surge tank built into the fuel pump pickup. You shouldnt have any problems with fuel surge until you get to around 1/8th tank, 1/4 tank is good insurance.

[QUOTE][i] You shouldnt have any problems with fuel surge until you get to around 1/8th tank, 1/4 tank is good insurance. [/B][/QUOTE]

On the STi, it has happened to me many times at a 1/4 of a tank & has happened at a 1/3 of a tank.

In the WRX it was much better and only happened @ or below 1/4 of tank.
WRX_Mundi 12-12-2003 12:14 AM

At the track I did not get fuel starvation until after the yellow light went on (yellow light turned on pretty soon after entering track, got obvious starvation on lap 5). Others have said that you shouldn't go below 1/4 tank, which is a Good Idea. Of course in my 2004 US STi, literally half a tank means slightly over 1/4 reading on the gas gauge, which is annoying. The first 1/4 of a tank is covered by the full through 1/2 reading.

No issues with oil starvation, but with only 4 track days who knows. I'd listen to John Felstead since he has a [i]lot[/i] more experience than most.
FSelekler 12-12-2003 12:18 AM

We just spent the weekend at VIR and each session droped the gauge 1/4. With four sessions each day, I was running below 1/4 indicator during the last session and have not had any fuel starvation issues. But it is good practice to always have over 1/2 tank while running on the track to preserve the fuel pump.

I think Keefe had some fuel starvation tho in his WRX, he might shed some more light to it from his perspective.

Davis... come to Mid Ohio again in April and I'll show you how you pass people at HPDE's :)

You have to use the far superior corner exit speed of the AWD to your advantage. If you want to pass you pull up along side the other car at corner exit and they usually get the picture and give you the point by as your front fender is at their driver's window. I can't wait until April as I have some serious go-fast equipment on the car now. :banana:

GuidoThePenguin 12-12-2003 09:07 AM

Only on an oval course (left turns only) would I see oil starvation maybe becoming a problem since the oil will all want to gather on just one side of the pan. I dont know where the pickup on the STi is.


In the left, right, straight nature of a road course, it shouldn't be a problem.

I'll be there.

About the passing procedure. Actually I do need to get closer to their car or at their 8:00 position when exiting a corner so I can get a good pass. I was in D (beginner) group so I usually kept my distance a little from some noobs (some who were actually dangerous) who just never looked into the mirror till the middle of the back straight. (passed em anyhow:))

EnduroShark: FYI, this club strictly enforces the passing zones and can only pass a car safely with a "point" from the driver to be passed. (passeed?) WE are all told to keep an eye in the mirrors for faster cars and let them by when approached quickly. A sfe group in my opinion.

I really look forward to the session in April. I hope to bring my DV camera with me and try to get a safe mount in the car that is acceptable to the Bimmer Techs.

Of course I wouldn't mind some rain for a couple sessions....muhahahhaa

Last time I was at the same track, I spun a rod bearing on my Celica, that is why I am so concern. It is true that the WRX STi is a much superior of a sports car compare to the Celica. But still I am worry in the back of my mind.

Do you drive an AWD car?

The difference in them being a noob by not following the line and someone being an ass by not letting you by is miles apart. I won't tuck up under someone I see is 3-5 feet off the apex or proper line. Generally you don't have to worry if you're not in the noob group.

There's nothing dangerous about it... I see them looking in the mirror, I take a wide entrance into the corner and come out in the middle of the track with more momentum onto a straight. This usually leads to my car being slightly along side theirs on a straight not in a corner. If you're always passive and just tuck in behind them, sometimes you'll never get a point by because there's no way for the other driver to know that you're not at WOT. If they don't point I lift simple as that.

Davis,

Bimmer techs? This is NASA dude :)

I'm going to get [URL=http://www.svtek.com/products.htm]this[/URL] camera mount as it's nice and simple. Requires a roll bar though.

Unknown STi in action. The 1st 3 were snapped as I was riding inside my brother's car. ( Original post I thought it was JDM Addict)

From my 3rd person view. I was impressed with the STi, it was very fast, especially acceleration-wise.

There were several nice cars out there today. The whale tail supra was very cool, espcially when it was shooting out 3 foot flames. I also had an EVO VIII hunt me down and pass me... :o :)

That is the absolute worst logic I have ever heard for passing without pointbys (and yes, if you are already beside another car you have passed without point) Coming out of a corner side by side with another car is dangerous, period not to mention against the rules. Do you know what a point by is for? The entire point is that the lead car is acknowledging you and knows you are there. If you pull that jackassery and come along side another car that doesnt know you are there you can easily get hit. If the flaggers are paying attention, hopefully you would get black flagged and pulled in for that crap.
How do you expect someone to see you to give you a point if you are beside them or in their blind spot?
Not to mention, if you are ending up at mid-track at track out then your line sucks.

Yes, he does (did, actually -- since he just sold it). Enduroshark has years of racing experience, not to mention HPDE instructor for PCA, BMWCCA, etc. He's a good guy and an accomplished driver.

Think about the message you are sending. I am assuming you are an HPDE instructor, right? I don't want to take away anything from your experience or knowledge but if I were your student and you advised me to do that, honestly I'd have to say 'no'. Too many things can go wrong, man...especially in an HPDE environment where you don't know the person's capabilities.

There are plenty of other ways to obtain a point-by without greatly increasing the risks to everyone. You know what I'm talking about. Fender-to-fender stuff should be left to the instructor group or advanced lapping days, not HPDE's.
