I'd use Mikalor clamps on boost pipes - the weight saving of Jubilees won't be worth curse word compared to the power lost from boost leaks. But are mikalors definitely better than good quality jubilees? Not sure what pressures coolant systems run at, but replacing the mikalors I had with good quality jubilees on the X1/9 fixed all my coolant leaks in one fell swoop... Don't you just love working on cars! It is always the most awkward bolt/nut that breaks or rounds or shears off! Well done on getting it sorted.....and inspiring us with your work. And it is nearly always the last one :-) Thanks, but I hardly think my amateurish efforts would inspire anyone, I see far better stuff all over this site that is way beyond my capabilities. Lays his own carbon fibre 'Amateurish efforts' Something's not adding up here

Pity you not running AC, putting a evaporator in front of the intercooler certainly will bring intake temps down.

How about sanding off the black paint and then paint it with bright aluminium paint - shiny heat reflective duct with no weight gain - win win. Thought about that but it would have very little effect due to lack of any air gap, paint will still get hot IMO. The answer was lying under the car! I have been dismantling my large curing oven so I can use the materials to build v2 in the new garage. The interior was lined with a double sided aluminium/foam sandwich insulation sheet. This has shrunk due to the high temps so I have ripped it out and a section was sitting under the car. Cut a piece off and stuck it on. It weighs 52gms :-)

52grms!! Maybe put some holes in it?

Not sure if it is of any help, but have just discovered a good source of lightweight stainless pipe. Mine is 35mm dia. and 1mm wall, if that. This wonder material is commonly available as the long tube on some vacuum cleaners.

Rear boot panel support frame roughed out and aluminium threaded inserts glued into the ends of the long sections. The short angled inserts are a little more complicated as they will be welded to fixing plates. Parachute support plate and frame fixing plate each made from 6 layers of 420gm prepreg carbon.

Making the parachute support is costing me nothing at the moment. I never throw away aluminium bigger than an inch square or bar/rod longer than 10mm so I have draws full of the stuff. This comes in handy for making small items, such as the junctions and fixings for the carbon rods. The rods are also from stock and the plates made from prepreg stored in my workshop freezer. The wood is used mainly as wedges to hold stuff whilst it cures.

Yep, I have an offcuts bucket for little bits and an offcut bin for bigger bits. Very often comes in handy!

Well, obviously, handbags and shoes are far more important than the stuff men collect :-)

Parachute support frame completed, just need to secure boot stiffening frame. If I had made this from steel it would have weighed in at around 3kg (both parts). Made from carbon fibre and aluminium is comes in at just over 600gms :-) The diagonal cross brace wasn't really required but it looked a little spindly so by adding it I will, hopefully, get fewer questions and comments :-) I made one miscalculation. When holding it together whilst the glue cured I needed to put a little twist into it to line everything up. So, as you do with metal, I over twisted it a tad in order to allow for a little spring back. Unfortunately, I had forgotten that carbon doesn't do that so I have a slight twist the other way. Unless you look closely it doesn't show so I will live with it.

Rear panel was a little floppy so added a brace in the boot. It works very well, but it is difficult to video very little movement :-)

Nice work but just musing if your boot lid would have given enough support once fixed in place ? James

Parachute removed from bag for the first time so I can get to the mounting plate. Now hanging up so the material can have a rest after a long squeeze. This should be done at least once a year if the chute isn't used during the season and also between seasons. Leaving it in the bag can have a detrimental effect on the chute material. I am guilty of this as this is the first time the chute has been unfurled since I bought it around four years ago. However it looks to have survived.

Looking at how to attach the parachute lines to the car. As the centreline of the crankshaft is halfway up the boot floor and the chassis starts around 600mm from the rear of the car, some careful thought has been taking place. I have decided to see if I can make a carbon extension to the chassis that curves up to crankshaft height. To that end I have made a mould - I look forward to the comments :-)
