Next years list includes-
1) work on thermal management ( double insulate anything that can ignite)
2) build spare engine
3) expand secondary chute box a bit.
4) run the car on chassis Dyno
5) build new rear fairings (maybe)
6) move outrigger on trailer
7) rebuild transmission in Denali

Aside from these items we should have an easy year in 2014.

8.) Find sponsor.  smiley

Loring next July is 1 1/2 miles with 1 mile shutdown. Wide smooth and fairly new asphalt.

Biggest problem is rear tires. If I try to put any power at all through those rear Mickeys, they will cord instantly and cost me $1500 +.

Rob......check this post on Target550. The tires that Marlo had prepared for testing in either the dirt or on pavement

have a 250 MPH rating.  http://www.target550.com/gallery/172_tires_tanks_reassembly/172_002_jpg.html

There are 7 fotos that relate to the tires and wheels.

You could call him if you want to. It is a possibility for future consideration.

Just hot off the phone with Tom at Roger Krause. Looks like the 30" x 7.00 x 17 Dunlop is going to work great for us !  They are out of them right now but will be getting more in soon. He made it sound like they will be available.
This could serve functions. We could run them at Ohio Mile while we do more testing and we could run them at Bonneville up to 250 for when the crew wants to make licensing passes.
I really wish the Mickeys came with another .050 of rubber on them even if they had to lower the speed rating on them a bit.
Ron Main said that they are getting about 12miles to a set of these tires. Does it really have to be like this?

What is the theory of these tires? At what point should they be retired?  We have some that have the cords showing but don't think there is any danger of running them with just two lines...

To the crew and Thursday nite builders of the most beautiful car that I have ever had the pleasure of working on,(There has been quite a few in my 60+ years)  THANK YOU grin
Aside from the 2400 mile trip in bad weather angry, it was well worth the round trip. I want to give Eric and Matt, who never got mentioned, and deserves a job well done on doing the sanding on the molds.
Rob when the car is ready and you have a venue to run close to Reno, NV.

Rob,
I noticed that your No. 5 on the "to do" list is to make new rear wheel fairings (maybe) is this from what was shown in the video of your runs on the mile? The upper leading edge appeared to vibrate.

SCCA doesn't play a role here.

Rex

Rex , the flexing was due to the really bumpy surface of the run way. Since the distances between expansion joints are the same, you can see in the video that the vibrating frequency goes up very linearly with speed. I'm  99% sure that this is not aero flutter.
On the same note really bumpy surface is relative. It's actually pretty smooth but with no rear suspension and 90 psi in rear tires, it was a bit rough.
