Heading to Savannah on October 24th

Work on our Datsun 510 was completed last Thursday with suspension alignment and corner weighting. Yesterday, we had an excellent opportunity to track-test locally at Homestead-Miami Motor Speedway with the FARA Group. The long work hours of the previous months paid off, as the racecar performed flawlessly. Test conditions were perfect, as there was little traffic, which allowed us to conduct conclusive high-speed testing and adjustment of our brake balance. The video shows part of this test before final adjustment. We thank all family and friends who showed their support and came to the test session.
Crunch time is over, as we are ready to race and have two weekends before heading 500 miles north to HSR’s Savannah Speed Classic on October 23-26.

Worked nine hours yesterday 9/27/14 getting the Datsun completed. Other than alignment and corner-weighting, the racecar is ready. A quick street test showed that “it works”. Next race is Savannah at the end of October.

Almost Back in Action

Although we haven’t yet raced this year, we expect to be back in action soon.  We are working very hard to get the car ready and have our sights set on Savannah on October 24th and Sebring later in December. A full season is planned for next year.

This short video shows some clips from earlier events at Road Atlanta.  We plan to race there in April.



Guess

Can you guess where, when, and who they are?

 

Clue: They are both racing drivers...

Update

We haven’t yet competed this year. There have been some setbacks while conducting maintenance/repair and we’re working on solutions. One delay was caused by problems with the installation of a hydraulic clutch release that replaces the fork release. We decided to switch to the hydraulic system because the increased force required for the competition clutch to release had already caused damage to the standard fork release (see pic of damage on our September 28, 2013 post). The installation of the hydraulic clutch release has been completed, although not yet tested.

We expect to be back on track after the summer, and will be providing further updates as we approach completion of all work.

2013 HSR Sebring Historic Races Group 2 Qualifying

This is a 6-minute video of selected clips of Saturday’s Qualifying Session, when we posted a 1:37.1; our fastest lap so far at Sebring.  At the checkered flag ending the session, the blue and gold #93 240Z of David Riolo passed us and, although he can lap faster than us, Alex gave chase while displaying the 510′s good handling.



2010 510 Gathering at The Mitty

A few pictures from the 2010 Datsun gathering at The Mitty. Although we trailered our 510 racecar, our street 510 was driven 1600 miles that weekend without a glitch.  This was our first visit and our first race at Road Atlanta and it was a very memorable weekend.

Update

Here’s a picture of the failed pinion gear from Savannah, with two teeth wiped out and damage to adjacent teeth.  Surprisingly, the ring gear was scored, but it did not break, so it’s a good paper weight.  We have now built a primary differential with new gears and new differential unit and a backup differential.  Both have all new bearings and seals and were adjusted for correct:

  • Pinion/ring gear mesh
  • Pinion gear preload
  • Side bearing preload
  • Backlash
In addition, we also have the low geared unit that saved the day at Savannah.
Our Datsun is undergoing some major maintenance and we may not race until after the summer.  We will continue to post updates until Moya Motorsports’ Datsun 510 is ready for track duty.

Another Savannah video.  This one is all from clips from hand-held camera.

Updates

There is work we wanted to accomplish last year during the summer off-season, but the timing was such that we would have missed Savannah and the itch to race was too intense, plus the car was running well.  As it turned out, our first event at Savannah was great; the same being said for Sebring a few weeks later.  The work we had postponed is now being addressed and will take a while.  We will miss the first race of the 2014 season at PBIR in February, but hope to be back in competition soon.
