Reverse-Engineered Fuse Box Cover — Kohr Motorsports

Some projects are measured in weeks. This one was measured in hours — and it's the clearest example of what reverse engineering is actually for.

The Challenge

During a race, header heat melted the fuse box cover on a Kohr Motorsports car. A small part, but not one you can just order a replacement for. There's no catalog listing, no supplier, and no time — a race team doesn't have weeks to wait on a part the size of your hand.

The Process

I took dimensions off the damaged original and reproduced it to match, then built it to hold up better against the heat that took out the first one. Reverse engineering a failed part has an advantage a clean-sheet design doesn't: the failure itself tells you exactly what the replacement has to survive.

The Result

Kohr Motorsports ordered three — one for the car and spares for the team — with discussions for future motorsports projects ahead. Turnaround was 24 hours.

That's the honest value of having scan and CAD capability in one place: when a part fails and nobody sells a replacement, the gap between "we have a problem" and "we have parts in hand" can be a single day.

Broke Something You Can't Replace?

Obsolete parts, discontinued components, and one-off failures are exactly what reverse engineering solves. Send me the part — or a scan of it — and I'll tell you honestly whether it can be reproduced. Request a project quote.
