F prod Miata folks, what are we going to do about the throttle body shafts? Seems like they keep on breaking.
David,

You may want to have Ken check with Jon B or Terry Barnard as they have a method that is better than the stock unit. This issue has been around for a lot of years and came to a head at the 2006 runoffs (...sure glad I was running carbs that year).

I have a design I've yet to try and will probably fabricate a few for testing.

Michael, use their stuff & it's not the first to break on this car. Two out of three Runoffs breaks. Once with Bryson & once with Kenny. The 1.6's break them in Spec Miata only their harmonics are not as bad at 7,200 as they are at 8,200 with a zing here & there. :wink:

I also have a design that I attempted to get Ken to use. Didn't fab because of his naw attitude. Now I'll fab it & if he dosen't want to test it I'll go else where with it. From a design stand point it will eliminate the garbage hanging on the end of the shaft along with better than the current OEM/modified support of the shaft. :think: Yup, was at Topeka for the initial BS with the shaft. Shall we say the state of U. was involved.

Last fall I talked with Andrew F. from CA. relative to his fix in 06. Some say legal, others say illegal.

If sharing design thoughts is advantages please pm & I'll d the same.
 
The 24 hour period from late Thursday to late Friday was a bit of a rollercoaster for me. Had a bolt back out in the trans that wouldn't allow me to get any gears in the center or right gate. That was repaired and we got the trans back into the car at about 12:30 after attending the Mazda party for a bit.

When I went out for my hardship lap, second gear was junk. I brought the car back to the paddock, parked it and changed clothes to go to work. Told Jesse P and Dan from Brass Monkey that I was done--no time to change the trans.

Ron Olsen from Barrington Performance (the builder of the trans) texted me that he had a spare, and Jesse called to say that they were already taking mine out. About and hour and a half later, Jesse called to say that he had just driven the car around the paddock and it was good to go. Obviously, I would have never made the race if those guys wouldn't have jumped in to do that so I'm grateful.

The loaner box had different gears in it than mine. They were close but not identical and that proved to be a challenge running in traffic. I was often between gears coming out of corners, especially 1, 6 and 12. By myself not too bad but not good in traffic.

The pace car was going a pretty good clip. About 58 mph which is faster than what I'm used to. and that was wound out in 1st in this box. Steve accelerated faster than that when the PC left us as it wasn't in his power band. I accelerated to match that and had to go to 2nd. Just as I hit 2nd the green came out and I got a nice jump. Half way from the start line to pit out, Kevin gave me a big shove and it was enough to clear Steve and take the inside into 1.

I led through three and Steve had the run going into 5. I've had people do the over/under on me in 5 and take friends with them so I decided to not block and try it myself. Well it didn't work out as Steve took Ken with him.

From there, Ken, Kevin and I fought back and forth. It was good fun but frustrating as we watched Steve getting away little by little.

At one point I did the old 2-1 upshift in 13 and that got me all discombobulated. As I was going through remedial stick shift school, Ken went to the outside in 14 and Kevin to the inside. Sorry about that guys. I needed to reboot. That really let Steve get away.

Ken and I were nose to tail when his throttle body broke. Not sure what he's done, but he might talk to JP about it as he seems to have a pretty solid program on our motors.

The next lap, I believe, was my fastest in clean air. At the same time, my brake pedal had gone soft. Need to work on more ducting. I think being stuffed up behind Ken and Kevin for so long may have been part of the issue as well. Steve was probably 10 seconds ahead and even though we were matching times for a couple laps, I needed to start braking a little early to make the finish and that sealed it. Kevin disappeared at some point as well. Sorry to see that too.

From there I just watched around every corner to see if Steve's bad luck would continue, but it didn't and that's good for him. He probably should have won the last 4 of these now going back to the last at HPT so he was due.

My car was really good. It handled very well. The obligatory product thanks go out to Hoosier Tires and their great radial. I built this car around them. Penske shocks, OS Giken differential, Hawk brakes, Barrington performance transmission (yes we had some development this year, but it shifted great in the race). Thanks Jesse Prather Motorsports, Brass Monkey Racing, Mazda and most of all my family. Its not advisable to build two race cars in two successive winters--especially when your wife is pregnant and you subsequently have an infant!
 
Congratulations Eric!

Nice drive, and kudos for having the class to thank Jesse et al for the gearbox swap when interviewed by Bisignano afterwards.

X2. Great racing despite all of the drama leading up to the event too. Really good to see you didnt let it mess with your head.

For what it was worth, the racing was very entertaining, so you delivered for the club in that regard.

I would imagine your day is due as well in the not too distant future. I hope I'm there to see it.
 
Thanks Fred and Rick.

Gotta give the credit where it's due.

I would like to win this thing. I think I'd probably take a year off of the Runoffs then because these weeks are killers on me anyway from a work standpoint!
 
I also wanted to make mention about Don Kraftson's effort to get on the grid. Anyone that was out there and saw the smashed Elva on top of the tire wall Thursday knows what I'm talking about. Great job just making the show and I'm glad the car wasn't hurt as bad as it appeared.
 
Sorry for the long winded report.

Now that I have had a few days to collect myself, I’d like to share my view of the FP Runoffs race and acknowledge some of the people that helped our team have a terrific 2011 season. Crew Chief Matt Longpine and I spent plenty of hours in the shop during the weeks leading up to the Runoffs. It never seems to matter how much time you have, you’re always working right up to the time you need to stick the car in the trailer. My wife Jennifer, as always, was understanding of our effort. I’m lucky the kids Monica (5) and Nathan (3) were taking it easy on her. Our new engine was falling short of our power goals on the dyno, but it did have a wider power curve thanks to some cam testing. At the Runoffs, I was located in the East Street Auto/Springfield Dyno tent which was located near champion row. I had 4 teammates for the week: SM Pole driver Jim, and other top contenders Pat, Craig and Luke. Tent atmosphere was perfect. By now I’m getting a few phone calls that Mike from Sports Car has recognized our season effort and we got a couple of mentions in the “Who will win” issues that landed in mailboxes right before qualifying. So now the pressure is on! I got to meet Mike for the first time at the event and enjoyed visiting with him. Q1 was wet and pretty much just a “make sure it runs, turns, shifts, and stops” session. Q2 we held on to P6 and my data showed plenty of room to shave some time. Q3 data showed much better driver effort, but the car was perhaps going soft on power. These two cancelled out and lap times were about the same dropping us to P8. By Q4 it was clear we had a problem with the car’s engine and we fell down the grid to 10th still sitting on the time from the first dry session. With less than 18 hours to our race, I was trying not to panic and I was glad to have Matt and fellow crew members Curtis Wood and Dave Volante to keep me grounded. O2 levels were getting leaner and leaner even though I put more fuel in my EMS maps. We took out plugs and gave them to Curtis who thinks that fuel injection is the devil. That makes him the best person to look at plugs. All those years with Alfas and carbs would finally pay off. We determined cylinder 4 was way lean and the other 3 seemed real happy. We checked with friends Jesse Prather and Terry Barnard and others for input and parts. Then I had my best idea of the week and caught a lucky break. The earth rotates and that means that RC injector is still open in CA. I overnight an injector to the track (paying more for the shipping than the injector) to be delivered a few hours before the race. My entire race is counting on the injector being the problem which seems like a long shot. The injector arrives on time and within minutes we’re on the dyno for a system check. What a relief that our power levels are back and the car has a very crisp feel now. A side benefit was the was warmed up for the grid.

Starting from 10th has me shooting for an “impound top 6” position. A no-show and good start puts me ahead of Mason and Bob both in Miatas. I also manage to pass Don in the Elva Courier (which looks like a 1980ish Avanti going backwards to me (Google it)) and Bill in the Nissan. Bill decides to pass me back a few corners later and the race settles for me. I hang with Bill and Charlie for several laps, but I eventually drop the draft and start falling back as Bill’s top fuel dragster Nissan continues to drag Charlie down the long RA straights. I have a nice seat watching them battle, but they’re just not slowing each other down enough to get me back in the game. A little over halfway, they touch and Bill’s off track in T8 and I go by. I decide to put my head down and see if I can make up some ground on Charlie now that he lost the draft and he has to be hurting on tires after his battles. Steve, Mike, and Chris from Goodyear had good product on my car and my tires were still completely hooked up, and a new lightweight driver’s suit from Charlie James at SafeRacer had the driver feeling good too! Several hard laps later and I do manage to catch Charlie and use the draft to pass him into T5, but he stays close. By now mechanicals have slowed or eliminated Ken and Kevin making our battle for the last podium position. Charlie stays on my bumper for a couple of laps and I feel I have him covered from T14 to T7, but he’s faster from T8 to T14. Charlie hustles it through the kink and uses the momentum and draft to get by going into Canada on the last lap. I respond with a big run through 14. An odd little slid and slip angle at the apex that’s hard to see from the coverage keeps me off the exit curb and somehow generates a run on Charlie despite logic. I catch the draft up the hill and pull out. A nice speed difference has me coming up beside him quickly, but I just ran out of room and he keeps the position by inches. The race can be seen on Speedcasttv.com and I have to congratulate Steve and Eric for the nice results. I ended up 4th with a best lap of 2:34.3 which is 3 seconds faster than with the wounded injector. Bill Recovered to finish 5th and Bob rounded out the “impound top 6.” Thanks to all who have helped. Sorry about the long winded report.
 
I think that I can summarize my entire week in just a few points -

Traveling to the track - my parents broke a shock mount off of the front of their motorhome somewhere in Chicago.

Q1 - New engine runs great in the rain without turning any rpm.
Q2 - New engine spins bearing after one lap, turning moderate rpm.
Q3 - Skipped while the broken engine in the trailer (damaged a cylinder testing a week before the Runoffs) and the new engine (that now has a bad rod bearing) are merged. A local machine shop is also involved.
Q4 - The car is back together but the Frankenstein engine is really soft.
Race - The car is warmed up early in the morning, everything is great. 20 minutes prior to grid we warm the car again but this time it wont start. Likely suspect is the magnetic pick-up (Huffaker piece) so I go through the paddock to find one. John Brakke gives me one and Rick Kavitski and his father show up and help my father put it on the car. At the same time I get buckled in and listen as the field takes the green. I actually started the race out of the pit lane 1.5 laps down to the field. I attempted to not interfere with anyone's race, but I did pass up to the 9th place car. I made roughly 20 laps all week.

Going home - the truck I am driving, pulling the trailer (with my wife and 10 month old son) breaks down 80 miles north of Indianapolis. We limp home over the course of the next 10 hours - typically a 3 hour drive.

Over the course of the last few years our car has struggled, culminating in this years Runoffs. Going from podiums and medals at Mid-Ohio and Topeka, to three years at Road America including a blown engine (first year), broken shift lever on first lap (second year), and finally this years issues.

Our car was the first FP Miata in the country (first Runoffs in 2002) and it's tired. Not sure if we will be back next year without a ton of money to refurbish everything that is worn out.

At lastly - I dont know how the Wisconsin state legislature managed to import weather from the first Topeka Runoffs, but is sucked.

Sam Hennry, I was there & still enjoyed your write up very much. Only one question, who is this guy Bryon you mention. :wink:

Fixed... I bought some parts from Bryson a few weeks ago, but please don't ask what circuits in my brain got crossed to make that leap... Ken was having a great run with a little bad luck at the end... Good run guys!

Man, what a week. Sorry to hear about that. I think you're right. Race cars need a ground up every so often and it sounds like it's time for your's. Sorry to hear about all the travelling issues too.
 
Listened to NOAA throughout the week.

Expected to hear "Partly shitty in the morning, turning to mostly shitty in the afternoon; becoming totally shitty overnight."

Mason - The race car stuff sounded like me last year. As for the weather, Ron, totally shitty pretty much sums it up. Where were we, the Yukon? I left New Hampshire, that bastion of warm weather, when it was 85 degrees and I was in shorts and a tee shirt. I arrived at RA and it immediately was 37 degrees the first nite, and 34 degrees another night soon after. When we got home it was back to 80 degrees again and sunny. Could the weather be much worse there? Do we need to hold the race in August to be sure it is nice?

Next 7 days day time temp in mid Wisconsin 70*. 8) Many of us from Wisconsin say, if ya don't like the weather stick around it'l change.:wink:

I'm betting Sorensen could tell of some cold a$$ed days in Atlanta, from back in the day. I know of plenty of un-pleasnt days at mud ohio since 1997.
 
Saw frost at Atlanta more than once, but it was many weeks later back then.

Most exhausting, least fun Run-Offs I can remember. (Snow at MO a close second)
