French Nova Trackcar

[Les Frangins]

Thanks everyone !!!!



Now, we are at the present day of the project.

The future evolutions are to change the final drive ratio and put a Quaife differential in the gearbox.





The original final drive ratio is 3.55 and we bought a 3.94.

We can watch the difference on this graph.

In blue, with the original final drive ratio and in yellow, the new.

The red line is the maximum engine torque.





Then at the same time, we will change the front brakes.

We go to put four pots brake calipers and two pieces 280x25.4mm discs with alloy bells.

Almost all parts are at home.

We just expect the discs and brake pads for make the mounting.


Two pictures of bells and brackets design.




The new differential and brake calipers.




And the machined bells.

Nice!!

[Benn]

Love the bells, will look great behind the wheels. Diff with be great in the car, will really really help in the corners.

Yum yum brakes

[Les Frangins]

Some news with the new rotors from HiSpec.


The final mounting is going to the end, we just have to do some rework machining on the bells and brackets calipers.

awsome project guys.

nice build from start to finish

[Les Frangins]

Thanks guys !!!

Following of brake's evolution !


Here pictures of caliper brackets.















Weight comparison between the two braking systems.


Single-pot caliper, disc Ø256mm ...

Almost 10 kg by side !






4 pot caliper , Ø280mm disc ..

8 kg by side


A weight gain of almost 4 kg on the front axle !!!


And we bought 2 air ducts with ducting hose to cool the brakes.




Mounting soon !

[Benn]

Wow they are huge looking. They will be a huge improvement!

[Les Frangins]

Mounting air duct.

We remove the front bumper and we draw what we'll cut.





After cutting !





When cutting, we removed an attachment of the bumper on the front wing, so we have to recreate it.
2 brackets are manufactured with an aluminum tube (light and stiff) .
We set an insert on it to screw the bumper on this bracket.









For air ducts, it's pretty basic.
We cut two oblong holes in the bottom of the bumper and after many adjustments (cutting, forming hot ...), we fix air ducts inside the bumper by 4 rivets.
