I'm heading out to PIR tomorrow. We're going to try a lot of new things on the orange car so it will be interesting to see how our changes work out. There's always a great group of people and cars here. We're very lucky to have such a great track and the Portland BMW club.

-norm

For all participants;

The gates open at 7am. Please try to time your arrival in the 7am time frame to reduce the congestion at the gate. We only have about an hour to register and finish tech. We ask that you be on time and move quickly through setup, tech and check-in so we can stay on schedule.


At the track:

As you enter PIR, you will sign the BMW and PIR waiver forms. Everyone entering the premises must sign the waivers. If you a registered participant for the event you will also receive your registration/tech form.

• Find a place to park in the paddock and prep your car for the tech inspection.

We prefer trailers to be parked to the west of the fast track café to help keep the sight lines to the pre grid from the tower clear.

• Drive your car to the tech line, with your registration/tech form and helmet.

Stay with your car until you have completed tech. Please do not put your car in the tech line and walk away. This can cause a disruption of the tech process.

• All vehicles must pass the at track inspection

• Once you have a completed tech form, please take your documentation to registration (typically in the Rose Cup room). At registration, you’ll finalize payment and receive your car number.

Put your car number on your car. If you only have one number set it will go in the center of the windshield/windscreen. If you have two number sets then one will go on the center of the windshield and the other would go on the driver’s side rear window.

What about driver's meetings?

We will hold two driver’s meetings:

We have two mandatory drivers meetings; one at 8:15am and at 12:45pm. We will explain the on track safety procedures, flags and passing rules. You will get updates on the track conditions, any changes in rules from what we have published in this document and an update on any open issues.

Passing Rules:

We will be using graduated passing rules for 2012 at this event (these are the same passing rules used at ORPCA events).

Novice and Intermediate Run Groups:

• Passing will be allowed on the front straight between turn 12 exit and the double cones before the braking zone for turn one. Passing on the back straight between turn 8 and the double cones before the braking zone for Turn 10.


Front straight passing is on the right side of the car being overtaken Back Straight passing is on the left side of the car being overtaken.

Advanced Run Groups:

• Passing will be allowed on the front straight between turn 12 exit and the double cones before the braking zone for turn one. Passing on the back straight between turn 8 and the double cones before the braking zone for Turn 10.
• Passing is also allowed between Turn 3 and Turn 4. Passing is on the right side of the car being overtaken. This is a pretty short zone, and requires cooperation between drivers.


Front straight passing is on the right side of the car being overtaken.
Turn 3/4 passing is on the right side of the car being overtaken.
Back Straight passing is on the left side of the car being overtaken.

Potential Addition: (passing rule will be discussed at the drivers meetings at the event):

• Passing is allowed between Turn 6 and Turn 7. Passing is on the right side of the car being overtaken.

Instructor Run Group:
The Instructor/Expert Run group allows passing anywhere with a point by.

The standard passing conventions should be followed in this group:

Front straight passing is on the right side of the car being overtaken.
Turn 3/4 passing is on the right side of the car being overtaken.
Turn 6/7 passing is on the right side of the car being overtaken.
Back Straight passing is on the left side of the car being overtaken.

If given a point by cars are expected to alter their line and speed accordingly so that both cars can safely go through a corner with no drama for either car.


Passing Safety:

No Passing in corners and the Car being overtaken stays on line (except Instructor Group).

The overtaking car is responsible for passing safely:

• If you are unsure that you can execute a safe pass within the rules proscribed above, back off and try again at the next safe opportunity.

All passes require a point-by:

• The car being passed in order to acknowledge that he/she is aware of the pass. If you do not clearly see a point-by, do not pass. This rule is largely self-enforced and demands cooperation between drivers. It also helps to raise the situational awareness of all drivers, which contributes to greater safety for all participants.

The Point by takes Precedence:

• You must pass on the side of the car where the driver of the car being overtaken has pointed. If you are unsure of the driver’s intent, back off and try again at the next safe opportunity.

If you find yourself inadvertently passing in a corner the two drivers involved are required to treat the track like a two lane street and share the pavement until one can safely take the lead again. Should this situation arise make sure to report to the black flag station where you get to explain why you ended up violating our passing rules and passed in a corner.

If you come upon a very slowly moving car (way off the run group pace) that points you by you may pass it provided it is safe to do so.

Track Safety is everyone's responsibility.

Stop at the Pre-grid black flag station for help with on track issues, for example;

• If there is a driver that fails to point by repeatedly.
• If the driver being overtaken prevents you from completing the pass • If you find a driver that is clearly driving over their head.
• If you notice and unsafe condition anywhere on the driving surface.

If you notice and unsafe condition anywhere on the premises please notify a Portland BMW Club staff member immediately so we can deal with it immediately. Help is always available at track control on the second floor of the tower.

Our goal is for everyone to have a great time at these events. You are the most important part in making sure that we reach that goal.

We look forward to seeing everyone on Monday.

Portland BMW Club

I see that you may have a problem with the 90db limit there.
We took care of that. We brought the exhaust all the way past the rear bumper and put a 45 degree on it with a v-band that we can point any direction we want (away from the sound meter). I wanted a 90 degree on it however but i think this will work for now. The new motor is also much quieter with the high compression engine. I'll post up pics tomorrow. :)

Do you have the wastegate tied into the exhaust? I would think the open dump alone would go well over 95db.

I dunno mabe make a pass by the river and have someone with a db meter on the side of the road.

On tracks they measure sound from a specific point, usually one of the observation towers. If you are familiar with the track you will know the location they measure from and you can modify the exhaust by angling the exhaust away from that location. An open dump, while loud, will exit towards the ground under the car and usually isn't a worry like an exhaust pipe pointing directly at the db meter.

Ya I'm aware of how they do this at Laguna Seca...Not sure about PIR though. I know if there is a wall beside the car it will reflect alot of noise from the open dump...w/e I imagine this rule isn't new for PIR either.

Nope. The car was actually very quiet with the high compression motor. We ended up removing the exhaust redirect.

Learned a lot about Yokohama slicks today. They definitely don't work cold. At first it was driving like an ice skating rink. On my last session I got them to 150-165-175 from inner to outer on the fronts and very similar in the rear. The car was lifting the front tire about 2" exiting the turns so they were definitely gripping. The GoPro batteries went dead on the last pass and the only footage I have is one of the rear cameras. But my laps were a bit slower than last time as we were still getting fuel starvation on hard braking. So we will have to run a surge tank. Crap.

What kind of camber were you running? Do you like the Yoko's more than the Hoosiers?
2 degrees rear camber, 3.5 degrees front camber. I like the Yokos better but there are scary until they are hot. Once they are hot they grip like crazy.

Chris are you going to start installing JP's new surge tanks as an option for our kits? I want one to avoid the starvation issues I experienced at Mfest at half tank fuel level. Providence mentioned doing the install in the carbon box in the rear...ideal for many as it keeps fuel system components out of the interior/trunk.

Would be a good idea imo.
