Finally got the Barracuda out for a track day at Thunder Hill Raceway in Willows CA last Friday on their 5-mile road course. It was basically a shakedown run to see how much suspension work I need to do to make it regular track day appearances. The answer was: alot!

The car performed admirably in the absence of a rear sway bar (had to be deleted to move the rear springs inboard 4" and the minitubs), the driver could definitely use some improvement as well

The good: The 426 ran cool as a cucumber during each 30 minute session. The 8-point roll bar made the chassis tractable and predictable and the 4-point harnesses kept me well planted in the drivers' seat. Overall, I consider the outing a success.

The bad: I went 4-wheeling during the initial session (went straight when the pavement went left at the top of a hill with a blind turn) which resulted in no damage to anything other than my pride. It made for a tentative rest of the day knowing I was going to have to drive the same vehicle home. The body roll was too excessive for this environment, and in several of the shots you can see the contact patch on the inside front tire was pretty minimal. The brakes seemed adequate (there was no fade) but the rotors should be replaced before another outing (subtle runout which isn't noticeable at street speeds but was rather unsettling at 120 MPH).

Next steps: bigger front bar, engineer a rear bar, reduce rear body height (2+"), new front brake rotors.

Had a great time with some friends who also drove (a couple Vipers, a WRX, an SRT-4 and a Z06) and look forward to the next outing.

Cheers!

Thanks Don!

For those that want to ride along................

The entire lap was executed in third/fourth gear between 3500 and 5500 RPM, even though it may appear as though I am going 20 MPH....

It didn't look like you needed to shift much. Manual steering?

Manual everything..........

Indeed, not a whole lot of shifting required. Spent the majority of the 5-mile course in 4th gear, with most of the technical 2 mile section of the course in third gear between 3500 and 5500 RPM, keeping in mind that I'm running 3.55's out back. 426 cubic inches helps with that...........

That's an awesome looking Barracuda. Cresting those rises looks a little spooky when you can't see which way the track is going on the other side. I love to ride along via. the gopro. :-) We need to hear a lap with the 426 at full song ;)

The 426 at full song..... I wish I could. I can put the music-free version up, but until I figure out how to set up the mic properly on the GoPro (or maybe mount the camera outside the car next time), all you can hear from inside the car is my furious Holley electric fuel pump!

I forgot about the angry buzz resonating through the interior alum skin in my old bracket car. I can only imagine that noise for 5 miles per lap!
