I guess I'll kick this off with a weekend report for Team RPM.  After a disastrous last outing at NCM with a crank angle sensor issue that plagued us all weekend, we were ready to see if our solution solved the problem.   Other than fixing the crank angle sensor wiring/connector and a few others issues the car was pretty much untouched due to our usual putting off of car prep until way to close to the race to get the mods done we want to.  

 

Saturday:  Were were a team of 3 due our soul crew member having an emergency that delayed their arrival until sometime in the afternoon.   He's our primary fuel guy, so would have to rotate duties and borrow people from other crews to help us on pit stops (Thanks Clowns Alley!) We decided that Tara would go first to get some experience with a damp track in case any big rain was to come in.  Unfortunately just before she went out, we discovered she could hear us, but we couldn't hear her over the radio.   With only moments to spare before lining up to get on track, we decided not to worry about it and it might be her helmet because it has had issues in the past.  She hadn't been in the car in over a year and it on AMP in long, but she did well and brought the car in clean and turned it over to Jeremy just before the two hour mark.

 

He also couldn't talk to us, but we discovered that if he keyed the mic it would at least flash the receiving light on the hand set.  So we worked out two clicks for "I understand" and moved on.  The rain had picked up some and Jeremy started to carve through the field using what probably looked like unconventional lines searching for the best grip.  With only one small heavy rain shower during his stint, it didn't rain as much as we hoped so we fueled the car rather than gamble skipping a fuel stop.   After his two hours were up, we pulled him in for our second driver change.  Tara had never done fuel in the car before, but she took her time and was done well within our usually limits, but in our haste we failed to remind Jeremy to check the oil after the fuel was done.  We usually burn some oil, but typically nothing of concern over one stint.  Myself in the car with nothing more than a few tidbits on where the grip I rolled down pit lane.

 

I'd been on the track a few times during damp and wet conditions, so I figured I'd get up to speed quickly.  We'll 2nd lap in, going though 9, the track reminded me to check my ego at the door as I went World of Outlaws style through the sand and out the other side with no damage.   Calmed myself down and worked on SLOWLY picking up pace.  Soon I was making my way forward.  The next moment of note I went to pass Castrol Prefect Racing down the inside of 1 while they were passing another car (light blue?) on the outside.  Well I guess the car on the outside didn't know I was there and pushed Castrol Prefect down into me and they both spun at the exit.  I wave a sorry hand and hoped it wouldn't be seen as aggressive driving.  Really got to me when  cam around 14 a few laps later and the lady in the flag stand was "playing" with the black flag.  I swear she was doing it all my stint to mess with me. 

 

I got lucky two more times with spins in 10 and 1 that left me parked in the grass between the track and sand pits.  Both times were due to the rear brakes having too much bias going downhill.  Luckily I didn't hit anyone or get hit and I just did my best to calm back down and get back at it.   I think by the end of my stint we had worked our way up into the top 5.   My driving hadn't saved any fuel either, so it was a stop for fuel and to put Jeremy back in the car with hopes of heavier rain the afternoon forecast.  I checked the oil before he went out and we were a 1/2qt low.   Oil in, double check, snug cap and away he went.  While we waited on the timer to click down to 0:30s I checked the tire wear and told him they would last, but just.

 

Well the rain never really came, I believe we were 3rd for a bit, but got passed by Cone Crushers.  Haven't seen their speed in the rain at Barber last year, we resided to just sit 4th and bring it home.   With less than an hour to go, we see Cone Crushers slow in turn 4 and Jeremy isn't far behind.   They picked up speed again and we kept a close gap until sadely Cone Crushers pulled to the side with a stalled car with no long left in the race.   Back in 3rd we let Jeremy know he had a 1 lap cushion between the car in front and car behind and just to bring it home.   Well as we head up to the observation deck and find our crew just arriving, we notice Jeremy's lap times have dropped by 3-5 seconds.   Thinking, well he's just saving the car, we nervously watch and he crosses the line.  Turns out the fuel light was on solid for the last 2-3 laps, which meant we had under 1.9qts of fuel left.

 

During post race we noticed that dipstick had popped up and Jeremy mentioned the car felt a little down on power towards the end. We also learned that we need to add some volumes to the fuel system components during post race impound.  Concerned the low oil had cost us another engine (same situation a few years ago), we checked the dipstick for sparkles and did a compression check.  Everything looked good, so it was assumed that in my rush I didn't get it fully seated and it worked its way up.   This is why not having Mike helping that day makes for chaos during pit stops.  After a few checks of the car and the rain coming, we headed to Dawsonville for pizza, beer, and bull cookies.

 

Sunday:  After surviving the storms of Saturday night in the trailer, we woke to the dark, but clear morning.  Scrub RS4s went on the car, front pads changed, and a little work on the radio with no improvement were done before I took the car the grid.  Well as I back into the spot and a Champ official runs over and tells us the transponder didn't trip while I rolled by.   So Jeremy and Mike start flicking circuit breaks and wiggling wires.   Luckily with moments to spare the power light comes on and stays on.   I roll around somewhere around 8th behind a parade of Miatas onto the track.  I think to myself, I might have a chance to lead the race if I play the cards right.

 

The green flag drops (I assume, I went by turn 16  taking their flags down) and I pass a few cars going into 1.  The track has similar grip as the day before, so I feel I can push sooner.  Soon I'm running 2nd behind our friends No Cents Racing.  Knowing they were local and had a lot more laps as AMP, I was content to follow them around and see what they know.  Eventually I'm close enough, they give me point by and I'm in the lead.  Being the first time I've ever lead the race, I do my best to keep calm and just keep a quick, steady pace and hand off a clean car.  A few laps in Jeremy let me know that Broke in 60 sec was half a lap behind but catching me fast.   Little did I know, that radio harness would give out not long after and I was left to my own head for the rest of the stint.

 

Soon I could see the Mustang coming behind hard.  One of my goals for the weekend was to work on being more defense with my lines without reacting to the other car.   They could me going into 9 and I just did what I could to make them have to pass me without being a jerk about it.   The were right on my bumper coming through 14-15 and as I turned in to 16 the car stepped out a little but I pointed it to track left for the straight.  Well that's were they were going too, so I got a little bump from them.  Nothing bad as we were both straight, but I picked up a few more MPH and while I thought I broke soon enough. I over shot and pushed us both wide exiting turn 1.   Well the little 1.8 wasn't enough to over come the 5.0L and was seceded 1st place knowing it was inevitable and hopefully they'd run out of fuel and/or tire before us.

 

A battle with Schumacher Taxi saw me spinning into the grass between the track and sand in 1 two as more fast cars approached.  A little miffed at what I felt was a little too aggressive a move, but I chalked it up to inexperience on my part and not having a proper exit strategy, cleared my head, and pushed forward.  Sadly that inexperience caught me again as when I caught back up to them, I blew my braking zone and spun trying to avoid hitting them and lost a spot to Castrol Prefect.  I decided to just finish my stint following them and turn over a working car.

 

It was decided to try to stretch fuel for 3hrs in the dry.  So we put Tara in for 1.5hrs to do a fuel conservation run.   When she went in, we learned of the radio harnesses complete failure and then the AIM dash decided to act up.  So she went out completely blind to information.  The dash would eventually boot up for her, but we didn't know.  After 1.5hrs, we brought her in and sent Jeremy out.  He loves a challenge so he really worked trying to maintain speed and save fuel at the same time.   The first full course caution came just a little too soon for us, so he came in leaving me exactly 2 hours to race.    15gals of fuel in the car and off again I went.

 

In 7th place,  I figured I had a fighting chance of gaining a few spots and maybe a top 5 if I just kept it clean and consistent.  I was told during the 2nd caution who were the cars in front of me, Schumacher Taxi and Momo.  (side note, we could turn the volume up on the radio and the crew could yell into it during cautions to relay information, it was the harness that feeds the helmet that died).  I could see Momo in the rear view, so I knew it was going to be tall order to catch them in my stint.   Restart and I work my way to clean track and settle into a groove.   Soon I see Schumacher Taxi coasting through 14 and was a little relieved I wasn't going to have to race them again.  Resigning myself to just finish I just drove.  Thats went noises started getting louder.   A groaning noise and some whiffs of Redline CV2 in RH turns told me we had either hub going or axle.  I'm the one who repacks them usually and I know there already gone.   I decided if vibrations started or the brakes got bad, I'd pit.    Well soon the noises go louder and started to be in LH turns too.  No increase in vibrations, so I get driving.

 

With sometime to go I see Momo Champ exiting Turn 5 and I leave 1.   Maybe I can catch them?   So I keep my pace and each lap I'm getting closer.  I'm trying to figure the gap every other lap or so.  Then I see a photographer in the flag stand.  I know we're almost done.   I keep pushing and they are getting closer.    I see the flag man with a finger in the air (the good one) and I decide to just push in case Momo makes a mistake.   As I exit 15 I know its done for and they finish 5.999s ahead.   I glance down at the dash and I turned the second fast lap time for us on my last lap.   Rolling into the pits, I didn't know if we'd made it to the top 5 or not.   Sadly we just missed out, but it wasn't for lack of trying.

 

Congrats to the top 5, it was a great race.   Beers were had, bench racing was done, and packed up and made it home safely.   Hopefully we'll see you all at Barber in a few weeks.   (yes, we'll be the ones doing the rain dance).

341 On Second Thought Racing Miata

 

91A8FBF7-9CF6-4C7D-96E5-D8367382E0EE.jpeg

 

Saturday we started near the back with the starting draw, first driver took a few laps to get used to the wet track and got in a groove.  At the end of the first stint we were sitting in the low teens.  The mixed weather throughout the day made it difficult to get consistent times, so we were somewhat conservative.  At some point we had some brake lockup issues which ended up flat spotting a tire (or two).  I got into the car for the last 2hrs.  Driving down pit road I could tell we were going to have some challenges under braking as the car felt like I was driving over a 1x4 every second or so.  The car vibrated like crazy the whole stint.  I had quite a few good laps mixing it up with the #35 BMW at the end.  Crossed the checkers in 9th place.  Post race in the pits we found that the RF tire was flat spotted down through the cords and almost through the belts.  Got lucky on that one! 

 

C049C156-029D-43AC-B098-45789CE70521.jpeg

 

Sunday we started in reverse order, so we went near the front.  I was in the car to start.  My teammates told me over the radio before the Green, be careful as it looks like the start of a spec Miata race out there.  Coming through 15/16 we were bunched up pretty good (with the sun blaring in your eyes).  Green flag dropped, and everyone held to the left side of the track not wanting to give up the inside, from what I could see it was all clean, which was surprising due to the wet.  I was able to hold position and create a little bit of a gap behind me, this gave me a little time to get used to the damp track.  The last 25 laps I had some good back and forth with the 747 Miata, fun times!  Pit stop and next driver out, lost a little time during the stop due to a hood pin issue, got back out on track in the upper teens.  2nd driver was able to get us back into 7th with about 10 min left in his stint.  He radioed in that it felt like a tire was going down, came in, all tires looked good.  Jacked up the RF, bad wheel bearing.  Ended up taking a little bit to get it fixed and back out on track, came back out 26th.  Ended up finishing in 16th for the day.  

 

All in all a good weekend for the team, aside from the wheel bearing and the flat spotted tire, the car went through great. 

 

We normally do 4-5 races a year, and at least from what we could tell, this was probably the cleanest/best driving we have seen in a few years at any of the races.  With the track going from wet/semi dry/damp/dryish in the same day I think every driver should pat themselves on the back for keeping things clean.  Congrats to the winners!  One of these days we might be able to put it all together and finish well enough to get one of those trophies!  I guess even if we don't, we still are having fun!

Surprising that a car that had the swap formula manipulated in its favor AND doesn't follow rule 4.5.6 does well.

I'm just glad to see they were able to baby it long enough to get it running at full tilt on a dyno this time, instead of developing a miss right after the checkered flag from the toils of a cool down lap.....

Had a great time this weekend, a couple of crazy moments, but I have to say kudos to everyone out there.  This was one of the cleanest weekends of racing I've seen in quite a while, even more impressive given the conditions we had.  Great to see so many familiar faces, as well as a lot of new (to me!) faces out there.  Looking forward to Sebring in December, hope to see y'all out there!

We don't run a header on ours.....

 

After dynoing between a stock manifold and the "header" it is a disadvantage to run the header vs. the labor to make a stock manifold work.

 

You can't tell me that the dyno proven difference of an s2 motor isn't worth making a team take the s2 point value....

 

Sorry for the thread derail....

The 204 they put down is in line with what other cars are doing at the wheels compared to same car factory numbers at the crank. 

 

The dyno procedure or lack there of needs work if it ever is to be anything other than “data collection”. “Only one pull because my car will overheat” is not a valid excuse nor is not going to very close to redline.

Taken a few races but finally had a result worthy of a write up.  We built the SC300 after Turn 11 at Road Atlanta destroyed the previous boxster.  After trials and tribs at watkins (nonexistant head gasket), indy (glass tranny turned to glass), and VIR (kinked clutch line roasting clutches), we were due for a decent result.

 

Drivers:  David Lampe @Zero_2_sixty, Maciej Tobola @macheesy, Justin Garvin @Chummy

 

Saturday

 

 

Dave's first race with the team and did everything right.  Steady, safe laps at really good pace including the fastest lap of the day. Started 18th, got out of the car in 7th.  Ran the full 2 hours without issue. 

Maciej drove second as the rain starting to come down.  The SC was the fastest car out on track as the rain was falling from a good combo of: car setup was spot on, tirerack.com tires were just right for the conditions, and increase of driver's life insurance meant kids will be ok. Up to 5th before fuel runs out way too early - still unclear whether it was underfilled or a loose cap.

Justin goes in third and only has a few laps when the clutch starts slipping.  To make matters worse, he gets called in for a fuel leak.  Turns out the gasket that holds the fuel filler neck in place had come out enough to prevent the gas cap from closing all the way.  Dumb stuff happens in racecars.  An extra stop was necessary anyway so David gets back in the car.

David's second stint and the clutch is starting to slip badly.  With 3 hours to go, we decide to fix it for Sunday while there's still some daylight

 

Clutch was ok, rear main seal was leaking oil all over everything behind it.  Repair takes sometime but after Justin proves he can bench press the w58 repeatedly, it gets put back together we pack it up wet but ready for the Sunday.  

 

 

IMG_20191026_205211.thumb.jpg.07213a4865136d26135265eeb7f73690.jpg

 

Sunday

Maciej starts the race in 12th and puts together a good run.  It takes about 90 minutes, but he gets the car into the lead and remains there until time to pit.  Good battles with Visceral and the 60 second mustang provide incentive to set the fastest time of the weekend for the sc.

Justin gets in next and runs good laps maintaining the lead.  Tires and brakes are holding up great.  Glass transmission feels solid.  Runs nearly 2 hours and pits in the lead.

Dave gets back in the car with around 3 hrs and 15 mins to go.  This is his first prefect race weekend and all of a sudden he's battling for the lead.  Careful driving is a little slower but no one wants to do something dumb first time out.  At 2 hours to go, we make a fateful strategy call to short pit under green.

Maciej gets back in to try to run the last 2 hours at full send.  15-20 minutes later the fcy comes out and all the rest of the leaders pit under yellow. 

 

We guessed wrong this time.  As green drops we're over 10 minutes behind first, by the end of the race the lead is down to just over 3.  But in the end, we did something to try to win the race.  Car's in 1 piece, 4th place finish, legitimate contender, no complaints.

 

Videos from saturday here if you had any fun with us:

Camera overheated on Sunday so nothing to show for it but the numbers.

 

Big thanks to everyone who helps get these things together and run as smoothly as they do.

Is there a link to pictures from the weekend that I just don’t see?

 

TURBO TATR #442

Our weekend was ruined by a mysterious ball bearing that found its way between the clutch disk and the flywheel.  
 

The car was running great until bad luck struck...
 

The bad part is I can’t find where it came from and the only place it fits in the disk is between the springs and you really have to push for it to pass through the gap.
 

Thanks to champ staff and everyone who stopped by To offer word of encouragement as we fought to get the car back out on the track.
