Eight and a half hours of work last Sunday included installing a new differential with the proper gearing. No other “major” work planned, but we estimate another 8 hours this weekend before heading for Sebring. Although we consider Sebring our “home” track, we haven’t been there since the catastrophic engine failure two years ago, when we suffered a crankshaft breakage at 120 mph on the back straight, causing an instantaneous driveline seizure that resulted in a very dramatic spin, as shown in the video that follows. Sebring has a reputation for being rough on equipment, but we hope to do much better this time.
Moya Motorsports’ first visit to HSR’s Savannah Speed Classic at Savannah Harbor Road Course in Hutchinson Island was a great success, although not all went according to plan. Entering the paddock upon arrival, the transporting rig was guided to an assigned parking spot, and the Team jokingly commented about a good omen as the spot was right in front of the podium.
Significant setup changes had been made since the last race and, although the car’s handling felt good from the start, minor suspension adjustments were made during the test sessions. The test sessions were uneventful until the last session, when Alex felt an unusual noise that seemed to come from the drivetrain. An inspection did not reveal any abnormalities. However, immediately at the start of the first of two Friday practice sessions, it was evident that there was, indeed, something wrong. The car was brought in on the first lap of the session and it was immediately diagnosed as broken gear teeth in the differential. A spare differential was installed and the car was ready on time for the following sessions. In spite of the spare differential not having the desired gearing, lap times continued to improve with each track session, achieving a 2nd Place in Class on Saturday and followed by a 1st on Sunday.
Moya Motorsports’ Datsun 510 will see action again with the correct gearing at HSR’s final event of the year at Sebring on December 5th.
We just completed 9 hrs of work this past Saturday and the Moya Motorsports Datsun 510 is almost complete, in preparation for the Savannah Speed Classic later this month. All that’s left is suspension alignment, which will be accomplished in a few days. Visit us in early November for a full race report.
Three weekends left to get ready. We still have a few things to do, like installing the gearbox, bleeding the brakes, fixing the the intake box, checking alignment etc.
Things were progressing well, but we pulled the gearbox and checked the clutch. The clutch was fine, but, as we were positioning the gearbox for re-installation, Alex spotted a crack on the clutch release lever. I don’t think it would have lasted another race weekend. A replacement is on the way. Obviously the load from a competition clutch exceeds the design capability of the stock fork. We’ll have to run four or five races with this setup, and hope it will hold, before there’s time for making modifications.
It’s been three months since our last post. We decided to do additional work on our Datsun 510 and it’s taking longer than anticipated. We missed our deadline for September, but there are four events left in our calendar before the end of the year. Soon we will post more details on our progress and report what our next event will be.
Our plan is to be back at Road Atlanta in September. We have analyzed our data from last April and, although we did well, are confident we can be faster. We have not been sitting idle these past couple of months. In addition to regular in-between event maintenance, we are doing major work that is normally done no more than once a season, including removal of all shock absorbers for inspection/replacement as necessary. With all the work still on our schedule, it feels like September is fast approaching.
This was our 4th visit to Road Atlanta and were the only Datsun 510 at the 2013 Mitty. Being such a challenging track, we took advantage of Thursday’s Test Day to get additional track time and, with 55 cars in our Group, we did three uneventful Test Sessions and two Practice Sessions on Friday. The weather forecast was not encouraging, but Thursday and Friday were perfect for racing. Our Qualifying Session was on Saturday morning, and by then the weather had changed drastically. We switched to our rain tires and qualified 3rd in Class, in light to medium rain and very slippery conditions. By race time on Saturday, the clouds were still threatening, but the track was dry and it was back to our dry tires. We had not planned to push for a fast lap until Qualifying and, since that session was so slippery, we went into Saturday’s race not having improved over our previous fastest lap from our last visit to Road Atlanta. We made minor changes to our fuel jetting and race strategy and did very well during the race. Our best lap improved over our previous best time, and we finished 2nd in Class (six cars in our Class) and 17th overall (55 cars.) First in our Class was a BMW 2002. Behind us were an Alfa GTV, another BMW 2002, a Mazda RX2 and a Volvo 122.
There was another race scheduled for Sunday afternoon, but it had been raining heavily all day; we decided to head for home.
Although Sunday was a washout, we were very satisfied with our results and improvements in strategy. Our Datsun 510, once again, ran very strongly and trouble-free.
We felt we were heading to this event better prepared than ever. All planned work and maintenance to our Datsun 510 were completed two weeks before the event. Modifications to correct earlier vibration problem were effective and the car was flawless. We went on track five times (two practice, one qualifying and two races.) The two Friday practices were run in wet conditions. In qualifying, we consistently beat our best time from our last visit to PBIR. We qualified sixth overall out of 22 cars and second in Class 2 (eight cars). Our best lap improved even more during racing.
The Saturday race was the most exciting; we ran a very close battle throughout the 8-lap race with a Group 3 Mustang. As expected, the Mustang could pull away on the straights, but we could reel him in through the tight sections and swapped positions a couple of times. The Mustang had passed us and was leading on the last lap, but Alex was right on him coming into the back straight and was able to draft the Mustang all the way down the 6/10th of a mile back straight. The Mustang tried to break the draft by shifting left and right down the straight, but Alex stayed on him as if on rails. As they approached Turn 10 at over 120 MPH, the Mustang brake lights came on. That was the signal for Alex to immediately pull out and out brake the Mustang, knowing that if we had the lead into Turn 10, we could hold the lead through Turn 11, the last turn before the finish line. We held off the Mustang, turning our fastest time during that last lap and finishing 1st in Class and 6th overall. Strategy played a big part during that race, as Christian kept Alex informed through our radio of any traffic behind us. Alex held off making the final pass until the last minute to avoid being re-passed. It was a clean race. We spoke to the Mustang driver after the race. He enjoyed our duel as much as we did.
This was our Team’s first 1st place. We repeated our Class win on Sunday to end a perfect weekend.
As always, we thank all who stopped by for a chat with the Moya Motorsports’ crew — Alex, Christian, Néstor, Jamey and Terry. We also want to give special thanks to Pierre Pomerleau for his outstanding photo contribution.

The first race of the year for Moya Motorsports and our Datsun 510 will be the HSR event at Palm Beach International Raceway the weekend of February 15th. We completed all maintenance and checks yesterday. Looking forward to the start of the new vintage racing season. Pictures and videos will be posted soon after the event.
We traveled to Georgia’s Roebling Road for VDCA’s Season Finale, December 7th through 9th. We were very upbeat after our first Practice/Qualifying Session, which easily beat our previous best lap time.
During that 1st 10-Lap Session on Friday, we were black-flagged after six laps because we were 2 decibels too loud. However, our lap times were very promising. With no particular starting order, we started 11th, but by the 3rd lap, we were up to 8th and 5th by lap 4. By lap 5, the only two cars ahead of us were a 911 and a Corvette Stingray. There were 16 cars behind us, including six Porsches, four BMWs 2002, a GTV and another 510. We were less than a second behind the fastest car, and each lap we ran was faster than the one before…We were cooking!
The noise issue caught us by surprise and, while Jamey and I accomplished a temporary fix, Christian and Alex used a cardboard template to buy a more substantial temporary repair piece for a backup. We have our own sound level meter, so we did a before-and-after test with our first fix, found we were well in the legal range and used it for our second session. Although our contraption was well secured and resulted in an acceptable level of noise reduction, it burnt with two laps to go (see pics.) We installed our backup repair, which held for the rest of the weekend.
The rest of the weekend did not continue to go as well, as the driveline vibration that plagued us during our previous race had not been completely eliminated, forcing us to run mid-pack at a conservative pace. Still, while running mid-pack during Saturday’s race, Christian notified our driver with one lap to go. Alex, vibration and all, decided to chase down one of the BMWs that had passed us earlier. It was exciting to see us coming out of the last turn, on the last lap, right behind the Bimmer. Alex pulled out of the draft and went for the pass, which we missed by just 0.072 seconds at the finish!
We started the Sunday Enduro and, on the first turn of the first lap, we were side-by-side with a 911. The 911 was on the inside, but could not hold on, spun right behind our 510 and was hit by another 911. This brought out a Caution and the Pace Car. After a few laps, we decided to stop for fear of causing further damage due to vibration.
