Hopefully in the next 3-5 years I can make it a reality.

As for my background I worked for Ford’s SVT engineering group for 6+ years and was part of several full engineering programs including spending some time on the Ford GT program. The engineering design and subsequent build that you have done on this car is phenomenal, and rivals the work we did on a $100M++ budget with unlimited resources from Ford and Roush engineering. This just reinforces the fact that a Kirkham is not just a kit car but an engineered vehicle that comes from talented engineers and craftsmen. I’m beyond amazed at the level of detail and engineering that was spent on every single aspect of the car by a relatively small group of individuals.

I did have a few questions regarding the transfer of knowledge from this endeavor to your regular production cars. Are you planning on taking some of the technology you developed, like the steering gear, the front and rear suspension, the tunnel shielding using the Aerogel, and other innovations and incorporating them into street cars?

My other question is the treatment/protection of the aluminum on both this car and also pieces like the billet overflow tank you sell. Do you apply any type of anodizing or coating to the parts to protect them long term from corrosion?

Please count me in on a book when you decide to go to press. I may not be able to afford a Kirkham at this point in my life but I’ll certainly find the $$ for a book on this car.

Sincerely,

Mike
Welcome to the boards!

Thank you very much for your kind words. I think any bunch of dedicated guys can pull of any thing they want to. I told Larry the car would have "no excuses" and that is how we built it.

We have already transferred much of the technology to our cars. Our cars are now coming delivered with CV 1/2 shafts. Our hubs have the drive pins milled right into them. I imagine we will be driving our rotor hats from the OD of the hub shortly, all in an effort to make our cars as best as we can.

The steering is so expensive to make, we haven't taken the leap to go into production on that part yet, maybe one day. The front and rear suspension are specific to the billet chassis. There is really nothing we can do to move that to our car. We have always stuck with the original chassis and that means compromises. The Aerogel is pretty nasty, dusty, and expensive to work with. I doubt we will be using much more of that. One thing we are seriously considering now is to make the footboxes out of aluminum so we can make them wider and deeper than the original car. We wouldn't change the chassis, however.

We did not protect the aluminum on this project with anodizing or anything else. Almost all of our parts are made from 6061 which is a spectacular alloy. It is rather strong and it is very corrosion resistant. We didn't anodize the parts on the car because anodizing etches the part and removes many of the machining marks. It also leaves the part rather dull.

Our tanks are not anodized either. Many people polish the tank when they get them and anodizing them would make polishing them quite difficult.

I will post on this site if we can find a reasonably priced place to print the book. Anyone with any suggestions, please let me know!

David
