What's the appropriate amount of time a driver has to wait under FCY before he can assume that the car in front of him (or 2 cars in front of him in this case) has had a mechanical issue and is incapable of accelerating and thus go around them?  Note that the leader took off 10 seconds ago.

Give it a rest man, isn't your yearly troll session over yet?

We get it, you're not happy about what happened, no need to post about it in another thread thinly veiled by phrasing the question slightly differently this time.

You weren't at the race and you're not the forum police.  Move along.

Luckily observing that you've made the same complaint in 2 threads with little to no difference in your premise doesn't require being at the race. 

We get it. Honestly, real talk - email Dana or Chelsey about it. It will achieve your intended goal much better.

We'll take it, slowest contending car there so to finish 4th is a win.  Car was down on power all weekend, we never are the fastest car but usually not as much off the fast pace as we were this weekend.  But Chris P, Casey, Chris H, and even me drove consistently, hit our pit stops, kept it out of trouble, no mechanicals, and just drove it and finished top 10 both days.  Thanks to everybody, I had a lot of fun just visiting and drinking the local fare after the races.  All the guys the guys around us: Mielan, Two brothers, cone crushers, etc you guys all made it fun to be there.  That's the way it should be at all of these races.  Seibkins, Route 67 with Tyler's bunch, all good times.  

 

Congrats to R Bank on the overall championship.  These things aren't easy, you guys made it look that way.  Too bad about the drama in impound, but it just seems to be the way it is sometimes. 

 

On to the next one.  Not sure where our next race in the Lexus is other than Barber in December.  I have a ride with Huggy at WGI next month.  See you all out there wherever it may be.

Which stint am I driving? ;)

 

We usually do that one with just us home boys but we do need to get together at one of these races.  Not sure why you would want to step back from that rocket you usually run to our car, but come on.

Things get hairy at turn 6 and 7 on Premium Dude's oil on Saturday sending at least 3 cars off track.  

 

 

 

Yah I barely survived that myself.

 

@enginerd what was the cause of the oil down?  I was suprised when I saw the car go back out, I was sure it was done for the weekend based on the length of the oil slick.

Can’t tell you how happy I am that nobody found the wall in that. 
 

@Ian Ultimately the oil cooler sandwich adapter to get the bmw oil cooler to mate with the new engine came loose. Probably repeated up and down movement on the hoses worked it loose (will have to make a bracket, and just tighten it more next time). So the adapter loosened enough to spill oil, driver caught a half spin in 6 due to own oil and continued until the oil pressure light came on at carousel entrance after pumping through 8 quarts of it. 
 

I put a bigger wrench on the adapter after we cleaned up the oil and we were back out practicing less than 2 hours after the incident.

Yikes.  That's a lesson learned for sure.  Our oil cooler uses a similar adapter, and that may be something that needs attention.  I had never considered the rocking of the engine leveraging the oil lines as a way of loosening itself.  Glad you guys were able to fix it, I was gutted the second time by when I saw it was your car in the grass.  The first time by I was too busy unclenching my backside after skating through 6.

Red loctite on that nut every time. It’s been a few years since I had a blow out but it’s a mess on a good day and a potential disaster.

Premium Dudes report:

 

Tested at Gingerman weeks before so we skipped the RA test. Teched, unloaded, relaxed. Applied decals and a big sticker from our new sponsor, Generations Pizzaria. Crossed fingers that we wouldn’t lose the third engine in 3 events. 
 

Larry started Saturday and hovered in the top 10. We knew that 2 hours was out of the question so we were pushing hard to make up the extra stop. Lap times were great. Late in the stint we get a radio call “oil light on, no pressure, turned off, tow coming”. Well shoot... our first engines lasted 10 hours.. hopefully this is an oil cooler fitting because it doesn’t make sense for the bearings to fail already. 
Turns out it was and the engine was fine! (Details above).

Now out of the championship, we tested tires for the rest of Saturday and prepped for Sunday. 

 

Sunday is send day, so we stuck our best driver in the car to start, raised the shift light to 7000+ and told him to “go like hell”. Curbs were open game and the plan was to either finish in first or break the car trying. Car ran flawlessly, drivers were almost flawless. Only issue all day was a slow leak left front discovered at the first pit stop, and the unscheduled tire change put us 20 seconds long on the pit stop. Ran top 4 with Tuttle / RBank / Visceral all day and finished a very hard fought 2nd, barely holding off RBank by seconds. 

 

Tuttle would end up with a DQ pushing us to 1st! Thrilled with the single day win but the real winners were RBank with the great combined finishes and championship win. Congrats to them! Somehow the car didn’t fall to pieces with their brake shake... I’m mystified by that. Any car should have lost every bolt it has with that amount of shaking.

 

Chelsea and team ran a great race (as we have come to expect) and I appreciate the thoroughness of tech. DQ for a big spender is a great way to establish confidence in the series for the budget teams. Weather was awesome. I liked the 20mph speed limit and the radar thing, nice to have consistency through all events. I also like the enforced sound limit... it was easier to talk to people in the pits. Bill said our car was sub 90 dB and I think it still sounded fantastic. 

 

Next race is Autobahn!

We have never had a sound issue but was curious what the number was. Bill measured us with his high tech meter at 85 and 87 dBa. For those of you thinking straight pipes and cherry bombs are necessary we have put our car on the dyno, made several pulls, pulled the rear tail pipe and muffler, several pulls again and the readings were either the same or maybe 1/2 Hp less which is just in the margin of error. We run a 2-3/4” straight thru MagnaFlow. Just passing along if you think you need loud for power. It just doesn’t work that way, in our case anyway.
