F40 LM Restoration

Awesome progress and thank you for sharing!

Question: If you're going this far with a project, why not do a complete rebuild of the engine and transmission while everything is out? Is the drive-train fairly new?

 

Great pics and progress Tim congrats!

 

Start with a bore scope???

 

This thread just keeps getting better by the day, thanks for taking the time to share the progress with us.

 

This picture is cool:

with twin wastegates boost is better controlled and if setup properly, allow for quicker spooling of the turbos.

Overboosting is bad which is what can and does happen with mechanical boost controllers. If the turbo shatters, you're atleast one turbo down if you're lucky. If unlucky, blown turbo parts get sucked into the engine and you'll be looking at a very very expensive rebuilt. Seen it happen more than a few times hence I've stayed away from mechanical ones.

 

Is Tapatalk being used?

 

Is there an echo,echo,echo in here?

 

Those pics make me want to take welding classes at my local community college, those people are true artisans in my opinion.

 

Doing it right the first time ALWAYS comes out less expensive in the long run than doing it cheaper the first time.

 

Is it TMI that this resto has grown my tree?

 

Beautiful. Is it regular aluminium alloy?

 

Tim, ask them if they're going to put a boundary layer in between the carbon and the aluminum to prevent galvanic corrosion. I'm curious as to the answer.

Great progress!

 

Probably. LOL

 

Interesting question. Offhand I would not have expected chemistry at a carbon-aluminium junction because carbon is not really a metal but I guess it is a concern. Here is a piece by Boeing relating to their carbon fiber 777: Aero 07 - Design for Corrosion This passage seems relevant:

"For example, graphite fibers, which are used to reinforce some plastic structure, present a particularly challenging galvanic corrosion combination. The fibers are good electrical conductors and they produce a large galvanic potential with the aluminum alloys used in airplane structure. The only practical, effective method of preventing corrosion is to keep moisture from simultaneously contacting aluminum structure and carbon fibers by finishing, sealing, using durable isolating materials such as fiberglass, and providing drainage."

 

One of my (four) jobs is in product development and testing. My primary material is and has been carbon fiber. This is a pretty well known thing and has been for some time. I have seen some serious failures as a result. I spent a lot of time testing products with experimental materials at the joining points specifically to avoid galvanic corrosion.

 

Good stuff! Your well of knowledge runs deep so thanks for sharing, I love to get learneded about such things, kudos.

 

Very interesting. And since this restoration would be expected to hold up for a long time, it seems worthwhile to take steps to prevent problems.

 

I put in my vote for this thread being the best one of 2013. I never stop learning from you guys and words typed on a keyboard cannot express my appreciation for the knowledge gained, thank you.
