I am going to get some aluminium laser cut to mount a cinqucento radiator and fan.

I have the basic profile and fan location but i've tried numerous different ideas to remove material from the left hand side to allow maximum airflow.

I seem to remember somebody had made similar for a radiator mount may have been andywaller? But the pics have vanished.

Is anyone more artisctic than me and have any ideas on what would look good?

I would say straight horizontal fins.

Hmm its close but i'm not 100% sure

how thick are you planning on going?

3mm should be sufficient. It will be bent at the dotted line and will be attached to the suframe with rubber mounts. And then a suppport from the top of the rad to the body.

That is going to stop a lot of air getting through the radiator

i would remove as much of the material as possbile, if its only a mount and its 3mm thick you only need to have it around 10mm in width offset from your outside edge.

You need to consider the surface area of the rad. Basically take the total area of the rad, then subtract the amount of metal (you will have to guess this). Then you are left with the air in the rad (I hope you are following this). You don'e need any more ait to or from the rad. What you will find is that it is much smaller than you think.

A lot of OEM fans create a route from the rear of the rad to force it through the fans, thus making the fan more efficient and not effecting the forced air performance.

I have the same rad and am planning on just a number plate sized opening. I need to work it out properly yet though.

speed didn't kill me, but taxation probably will

Basically the 3 lugs are the mounting points on the rad. The fan hole is positioned where it needs to be and the rest of the material i can lose.

This will be behind the rad, and the fan is a pull fan. It sits approx 5mm from the core.

why dont you leave metal where the core is on the rad... and just have it machined out where the fins are?

I have just had my cinqucento rad out. Basic measurements show that the surface area is 96600mm sqd. I then looked at how much material that consisted of and it worked out about 57%. So in theory you only need a hole about 42000mm sqd. This is as I guessed about the size of a number plate, which suits my build.

Sorry i'm being a complete dullard. So you mean that the rear of the rad only needs a 42000mm sqd opening in the cowling?

Well basically yes. There are only gaps for 42000mm of air to go through the rad so any bigger than that behind the rad is not needed, in theory at least.

I always find the best thing is to design things like this as quite restrictive and allow for extra holes to be drilled if it gets to hot. that is how we 'tuned' the cooling on the hillclimber.

Perfect will have a play on the cad program and see what i can come up with.
