As an ongoing project I have been hotting up my F6 over the years.
To start with I put in a Renault 5 TL engine.
That is a 956cc engine with more 10 HP then the original F6 1108cc 34HP.
Last autumn I found an Abarth sport exhaust for a Renault 5TL and a Deauville spaghetti exhaust manifold that was made to fit a Renault 4.

Last Tuesday I put the Abarth exhaust underneath the F6. The only adjustment I had te make, was a piece of flexible exhaust pipe to make it clear the upper suspension.



with this exhaust Im marginally faster. And the engines reaction to the throttle is better.
Today I started to make a mock up for the spaghetti exhaust manifold.
I put an old engine that is waiting for rebuilding in an engine mount so I can work on a normal hight.

And I put on the wrapped exhaust manifold.
Wrapping keeps the exhaust fumes hotter so they leave the manifold at a higher speed and gives more power.
And I put on the separate inlet manifold with my spare Solex SEIA carburetor.

I also made some adjustments to the traverse that runs in front of the engine because the original is not clearing the manifold.
An update follows when I'm putting in the manifold
