Twincharged, Wide-arched Convertible Peugeot 405

[Col 666]

Mad! What sort of rollover protection are you going to have?

[davetibbs]

For the rollover protection, other than extensive strengthening in the A pillars and windscreen frame (which I appreciate won't do much in the event of a rollover, but every little helps!) I'm going to use the electro-magnetic rollover hoops from the E46 convertible - main reason being that they can be tested and reset, whereas ROPS hoops from other convertibles such as the Peugeot 307cc deploy using an explosive charge, and I won't be taking the car near a road (or indeed a BIVA test) unless I'm totally happy with the system, and I can't afford to keep replacing the charges after tests! These ROPS hoops can be fitted to a frame behind the rear seats which will double up as extra bracing/strengthening.

As for their control, I will probably use the gyroscopic sensor from a car that keeps ROPS deployment separate from the CANBUS wiring to simplify the wiring! More investigation needed on this bit though.

Outstanding! Looking forward to updates!

My mate told me he thought Rollover Protection would be too much effort. I showed him this video.

this can only go one way

This is utterly crazy, in the best possible way - will be following this with interest!

[Cledus Snow]

I don't wish to piss on the OP's chips but, is this going to need an IVA test?

[richard300]

I look forward to seeing this build develop and i take my hat off to your talent!!
I think that the car would look just perfect with the factory MI16 bodywork and trim and some sensible aftermarket wheels, as if Peugeot had produced the conversion themselves (Kinda' like my ropey MS Paint rendering below):




But i guess you need extra scoops and bulges etc to cater for everything thats going on under the skin.

I wish you lots of luck on this epic build

[davetibbs]

Yes, it will need a BIVA, and I've known this from the minute I started the convertible conversion, so it's not pissing on my chips It's something I intend on working to get - it's entirely possible to get an IVA for a monocoque-converted-to-convertible, providing it's done properly. Many late nights have been spent studying the test manual, but if anyone has any advice it will be most welcome.

[davetibbs]

It does look awesome as a convertible in standard Mi16 trim (great chop by the way!), but a lot of the bodywork modifcations came before the convertible conversion, and as you said a few of them are required.

I'm trying not to make the bodywork mods *too* lairy.

[NotDave]

You do realise that you're completely, and utterly, beyond insane right? But in the most brilliant way.


Are you a mech/elec engineer or something by trade?

[davetibbs]

You're very kind, I actually work in IT. I've just done a lot of learning over the years

[NotDave]

Not got some CAD experience to do a 3model of the car, including stress tests?

[TEKNOPUG]

All I can think is "why?"

Still, sounds like a fun project. Did you take any inspiration from this?

[davetibbs]

Standard boring response: Why not?

Longer answer: It's been a project car (actually my first car) for as long as I can remember. Plans have expanded further and further over the years to the extent that it's reached a point where I want to see just what is possible. And at the end of the day, it was just a Peugeot 405 GL, so it's not like I'm chopping up a classic car.

I'm loving the technical challenge of it, and learning a lot in the process. Thanks for all the support

It's good you're putting all through "by the book", even though it'll be a long slog. Best of luck with it though, I think this is going to be a pretty special build.

How much power are you looking to make? Looks a very intresting project.
