A hole new begging
This is the start of scariest thing I've done to my Alfa yet. Having decided that I would like to become more 'hands on' with my car, I have taken on a new project.
In order to get as much cold air as possible into the air intake (K&N), my car needs a vent in the bonnet. This is nothing unusual as many modified cars have vents and scoops. But few have Properly designed NACA ducts.
A NACA duct is an air intake designed by NASA in the middle of last century. For a good few years it was top secret. By the 60's every body had worked out how they work and the best places to use them. The whole idea behind a NACA duct is to intake air at a slightly increased pressure without creating drag in the air flow of the vehicle.
One of the most famous uses of NACA ducts is on the front of a Ferrari F40.
Why is this such a big deal for my car? Well I'm going to make it myself. I have never used Fiberglas before and even more scary is, I've never made a big hole in the bonnet of my car before! [img]smilies/eek.gif[/img]
The first step is to make the mould for the Fiberglas. I've just come back form the hobby shop with a load of balsa wood.
I have already designed my duct and I will make the mould over the weekend..
WATCH THIS SPACE!
Monday should be test run on spare Fiberglas. All being well then Tuesday/Wednesday should be the real thing.. gulp :/
I will have my car back from the garage on wed/thurs so Friday is the BIG day.. the day I cut a hole in my car!!
Then the weekend should be fitting and painting [img]smilies/smile.gif[/img]
I'll post up all the developments during the week. wish me luck!
Oh and any tips would be much appreciated.
if life was easy, everyone would do it.
