Thread: Bundalene's Puma project

Mmmmm time for a chin wag and a beer if you have time Erich, this weekend maybe??

Baz.

I spent a few hours on the project today.

Firstly the firewall engine bay side was stripped, cleaned, roughened with wet & dry, painted with a rust inibitor - sealant and bits were replaced.



Left side stripped down and scuffed













Paint used, similar product to POR15 but cheaper and Australian made.

RustSeal by KBS Coatings - Better than POR-15 - Stop Rust with our Paint / Sealer










End result after the bits were re-installed. Very little of the firewall is visible after the car has been re-assembled.











Also, connected all four earth points on the firewall. I used 6 sq mm and high quality lugs. These will be connected back to the battery earth on the chassis adjacent to the battery box.

Computational fluid dynamics (CFD) is one of the branches of fluid mechanics that uses numerical methods and algorithms to solve and analyze problems that involve fluid flows. Computers are used to perform the millions of calculations required to simulate the interaction of liquids and gases with surfaces defined by boundary conditions. Even with high-speed supercomputers only approximate solutions can be achieved in many cases. Ongoing research, however, may yield software that improves the accuracy and speed of complex simulation scenarios such as transonic or turbulent flows. Initial validation of such software is often performed using a wind tunnel with the final validation coming in flight tests.

such calculations also came in handy when "they" were exploring the feasibility of replacing arteries with vein material for cardiac bypass operations 30 yrs ago ... sort of ironic isn't it

Has anyone modified the area of the Puma, around the air cleaner, for better access ro replace the filter. I was thinking of modifying the inner guard to drop the filter by 20-30mm. This will be suitably re-inforced and bracketed. I have the inner guard at the fibre-glass fellow for repairs currently.


Just for info, the inner guards look like a plastic material but are actually press molded fibreglass.

Erich, just remember you will need to get the hose from the intercooler to the turbo down that side. It actually sits under (along) the bottom edge of the air filter box as the fan cowl protrudes to far across. I think if you remake the hose in metal piping you will be able to over come this.

Great progress Erich! You may have mentioned, but what are the planes for this vehicle when you finish it?

Currently we have 2 registered cars, a 1999 TD5 Disc and a 2006 Defender. The plan is to retire the Disco and replace it with the Puma.


Buying the Puma was a spur of the moment thing - I went to the auction with no real intention of buying it, until I sat in it, with the leather and all the extras. I bid on it and no one else went along with the bidding - lucky on the day. Worst case I could repair it and make a bit of money.

To be honest, I don't know why the insurance company didn't have it repaired.

The chassis was picked up by the repairer today, should be back on Friday. Unfortunately for us we are helping friends move this coming weekend, to there will be little progress.

Also I have been told by a few people that the seat base and tunnel of the Puma gets quite warm / HOT on long runs. Is this because of gearbox temperatures? I see there is no cooling line like the R380 have. Also the exhaust runs quite close to the gearbox and under the front of the transfer box.

I plan to insulate the floor under the cubby and under the tunnel with a al backed foam material I bought a while back. I was also considering either wrapping the exhaust from the manifold and down to the gearbox, plus a heat deflector. Also some heat sinks on the flat plate of the transfer box. All this is easily do-able while the vehicle is apart. Any thoughts - please be critical if you think I have it wrong, as this vehicle is new to us and a steep learning curve.
