RICHMOND, CA-May 28, 2009. The National Auto Sport Association (NASA) is pleased to announce that Pfadt Race Engineering will offer nearly $20,000 in gift certificate rewards to the top finishers at the 4th annual NASA Championship event at MillerMotorsportsPark on September 10-13th, 2009.
The 2008 NASA National Competition was an impressive event for Pfadt Team Members.Pfadt Corvettes won podium finishes in ST-1, ST-2, TTU, TTS, and TTA confirming our belief that our line of suspension products gives our team members the competitive edge.We are excited to continue our support of Corvette racing at this year’s event and expect great results from all of our Pfadt Race Team members.
The award program will apply to all competitors competing in a Corvette at the NASA Championship event. Any competitor that scores points racing a Corvette during the weekend will be eligible for at least $50 in Pfadt Cash regardless of finishing position which can be used for any products or consumables on the Pfadt website.
The contingency program will award drivers a “Pfadt cash” gift certificate in the amounts of $500 for first place, $300 for second place, and $200 for third place if there are five or more starters in their class. Applicants must be a registered member of the Pfadt Racing Team prior to competing for contingency rewards. Joining the team is easy and details are available by visiting www.pfadtracing.com or by calling 888-972-2464.
This program applies to all Pfadt Racing Team entrants or competitors driving or racing a Corvette during a NASA Regional race weekend.
Decals must be displayed and will be provided upon joining the team.
When registering for any NASA event Pfadt Racing must be listed as one of your sponsors.
To collect your award, you’ll need to contact Pfadt Race Engineering directly. Please note, all contingency claim forms and finishing results must be submitted no later than 21 days after the Championship event to qualify for contingency. Pfadt Racing Cash certificates will expire 4 months after the date of issue.

We just wanted to give you a small picture of what is involved with designing some of the parts in the new Carbon Fiber Driveshaft.
Here we will highlight the development of just the aluminum drive end that is used on both ends of the carbon fiber tube.This part started life in SolidWorks as a very simple cylinder with the appropriate holes for mounting to the flex disks.From here loads are feed into the model and the stress level is observed.
Here is an example of one of the first drive end models weighing in at 1002 grams.
From here we look at the stress and strain levels within the model and determine where we can remove material without sacrificing strength.This process is repeated until target weight and strength values are obtained.
Here is the final product from this optimization process.
Below is a picture to give you an idea of what is involved.Each blue background picture is a different iteration of this process.The four center pictures show several different analysis of the final version of the drive end which weigh in at 235 grams!
Asking $70k. I have a lot of spares, those are negotiable.
This car was NASA ST1 National Champion 2008. It was 3rd in 2007.
It is built to NASA ST1 specifications. It can run in NASA ST1 and TTU
The car easily turns 1:57s on the outer loop at Miller and is sub 3 minutes on the full track.
This car ran 1:28s at Mid-Ohio and 1:51s at ThunderHill.
The car is wicked fast and easy to drive. Just ask Danny Popp.

If you’re in the market for coil overs, add another great option to the list. Well, add it in February 2009 because that’s when the new Pfadt Featherlight Generation coil over series will be available.
We’ve been testing prototypes on our cars and on the shock dyno for about a year. We’re finally close enough to having our first production batch ready that it’s time to share!
Yesterday Josh and I were working on some final dyno tuning. Take a look at the shock on the dyno…
The Featherlight Generation of coil overs from Pfadt have a lot to offer:
1. Inverted design for lower unsprung mass
2. Aluminum body
3. Made in the USA
4. Pfadt custom delrin spherical mounting system
5. Hypercoil Springs (rates to be released soon)
6. Single adjuster for both compression and rebound
7. Adjustable body length allows ultimate ride height flexibility
8. Non-emulsion design with separate gas chamber
Ultra-light weight like the name implies, the Featherlight coil overs from Pfadt will provide the ultimate in construction, design and easy track-day tuning.
The adjustment knobs are easily accessed by reaching behind the wheel so you won’t have to modify your car. The really cool thing about the custom design of our adjustment knobs is that by Summer 2009 we’ll have available in-cockpit adjustability. You’ll be able to tune your suspension damping from the comfort of the driver’s seat. Stay tuned for the cool features and interface of this option!
This launch of the Featherlight Generation single adjustable coil over is only the beginning. Our next coil over launch in mid Summer 2009 will be the Featherlight Pro Series. The Pro Series will feature an external remote canister and independent 2- or 3-Way adjustability.
Expect introductory pricing to be $2500 - $2600. February is only a few months away!
It’s official - we’ll be campaigning the only Corvette at the 25 Hours of Thunderhill!
We’ll be running our Pfadt C5 and have a great team of drivers. Along with myself we’ve got Danny Popp, Dean Conti, and Norm Goldrich. Norm isn’t really a CF member, but he is a fabulous driver, so we decided to let that slide.
Everyone came in to Salt Lake for a shake down and to work out some of the plans. Here’s the Gang…
Dean, me, Norm, Danny
Our real goal for the race is to simply finish - which is easier said than done. Since Nationals we’ve been working to add 25 Hour reliability to the car. One of the big changes was that we added C6 fuel tanks. The C5 tanks starve for fuel sooner and based on our calcuations would have had us stopping for fuel every 50 minutes or so. That’s a lot of lost time and it makes it difficult to rotate drivers.
We also changed the head gaskets to lower the compression so we could run pump gas. We had the car on the dyno on Thursday and everything was running well, but on the practice day on Friday we had a TPS sensor fail. It was frustrating and posed obvious difficulties for the drivers to get good seat time.
Eventually we got the car working well and everyone got valuable seat time. We practiced driver changes, and have a good feel for what we need to do.
The only downside to all of this is now Danny has time on my home track on the same configuration they’ll run at NASA Nationals next year!
The 25 Hours of Thunderhill starts at 11 AM on Saturday December 6th and ends on Sunday at noon. We’ve got a great staff coming together to run the fuel stops and tire changes. We have about a million things to do this month to get the car as ready as possible.
