F40 LM Restoration

I assume you are happy with Mechanikers info, but if you need more info, let me know.

 

Update on the mechanical side of things having now spoken in more detail to those whom were there on Dyno day, and we have agreed a plan.

It was somewhat of an un intended result that we actually got that 604 reading, regardless of the ensuing discussion, as that was not the point of the session. The real point was to ensure that we had successfully integrated the Motec installation with our new engine and turbo set up, that all was good on the engine installation and know we are producing adequate power. That told us we need to fit new injectors to get enough fuel into the cylinders for when we ramp the boost up and go for power. If we fit the injectors now, we will have to have another dyno session just to get the engine to run satisfactorily, but with so few hours on the new motor, we would not be in a position to do a full power run. In short, pointless.

Consequently, we have decided to finish off the car and actually get it on the track for a limited shakedown and see what other issues we have to resolve. We then need to get a total of say 600 miles or so under our belt to ensure the motor is properly bedded in.

After that we will fit the new injectors and return to the dyno for a full power session, turning up the boost and revs, as right now we have kept it low so as to minimise stress on all components. We also have to decide where to fix our rev limit, 7,500 being safe, but we are pretty confident we can go further, again something for the later session. I am thinking 8,000.

Overall the plan after a hard and expensive 20 months is softly softly, tempting though it may be to rush things and just go for a big dyno figure.

It will probably be a combination of road and track, given the car will be road legal, however, it will definitely start on track and it will take what it does, but hopefully not too long.

 

The core we used is made by " 3D core "contact details www.esccomposite .com .......... all layers are held in place with the contact adhesive which must be used sparingly as over application will weaken the components resin.

I believe that type of honeycomb is used with Prepreg as the Carbon Fibre material only adheres to the surface areas of the honeycomb . If we used that type of material with the resin infusion method all the voids within the honeycomb would fill with resin resulting in an over heavy brittle piece.

 

First of a series of pics showing the three " sacrificial layers " being laid down with spray glue, which will enable the expoy resin infusion.

The 1st stripy material is a rip film, the 2nd layer is " donut paper " and the 3rd is a netting which maintains a space which aids resin flow when a vacuum is pulled. The butyl strip which will adhere the edges of the vacuum bagging is in place but covered with a protective tape to keep it clean.

Original and flattering-thank you and I hope we manage to keep your interest for the rest of the project.

And now the piping to infuse the resin.

Hoping to see something in the next few days so might have something to post as a starter next week.

 

Just for interest, this is the cordless cutting tool used to trim the CF.
