F40 LM Restoration

Ah I can see now that the perspex headlight covers are smaller than the ones you will actually be using on the clam, so they do allow the indent for the correct size ones and that part of the mould they cover will probably be cut out.

The headlight bucket no doubt will then be moulded separately and the finished items bonded to the clam from inside.

 

looking the molds I see that the lock system in LM and Standard version is different... How lock the front hood with the quarterpannel in the LM???

 

I'm still confused on how they get your original bonnet out??

If the mould was made in one piece then you would never be able to pop the original out of the mould, as the original would be captured in the mould by some of the internal curves. You simply detach one section of the mould at a time along the flange points until such time as the main flatter part has room to pop out.

Think of it like a suit of armour, you need to detach each section around you in order to eventually get out.

The original will come out like jelly comes out of its mould, or a cake out of a cake tin, as long as the surface tension is broken between the gelcoat and the original via the hand wax and release agent on top of that then it should pop out nicely, the problem arises where the odd spot is missed and the gel coat bonds directly to the original.

To make a part you then bolt all the flanges back together, fill any mould joints with clay, wax the mould a few times, apply a layer of release agent, then gel coat the entire mould and start laying the laminate.

 

Sounds sad but I love that jack.

 

More images of molds please . I like to see this finish .

Could you show the lock system of LM, is different with the OEM lock system in F40

Harbor Freight, I have 2 of these exact low profile jacks. You can spot the color a mile away lol. It's actually lasted a few years now compared to most other cheap crap they sell

That one is probably sold under Snap-On or some other brand name but it's the same OEM.

 

Yep I have one -- mostly aluminum and they are good value for the money.

Nice power! Wow

 

That's an extraordinary output given the low boost pressure.

 

I'm no expert on such matters but I guess one moves to bigger injectors if one needs to flow more fuel.

Personally though, I'd question the chase for power and settle on what has already been achieved. 600+bhp at the rear wheels is more than enough for this beauty. What drivers will you have that can handle that power (and more) without putting the entire project at risk?

I'd be over the moon with that level of output and if it can be achieved with a red-line and boost pressure that doesn't risk the motor I'd be all the more happy. It's a very light car and is going to go like a rocket with that power-to-weight anyway.

I've seen / heard of too many boosted cars melting bits & pieces. My inclination would be to call it a day and just work on making it super-smooth and responsive.

p.s. Please feel free to ignore everything above and do what pleases you. Following your thread has been a joy and an education.

 

Fantastic power already!

Is it a 2.9, 3.5 or 3.6 engine? I've completely missed that in the thread...

 

What fuel pressure are you running? Might be able to squeeze the extra flow you need out of the existing injectors if you bump up the pressure and your pump can keep up with that.

 

You won't be able to turn up the boost until you sort out the fuel issue. Running a boosted car at max fuel capacity is a recipe for disaster. You likely need to go to a larger injector as well as a larger/higher volume fuel pump(s).

Do you know what specs you currently have for both?

Tim, my engine management set up is similar to yours (MoTeC M800 and CDI-8). Also switched to the newer Bosch EV14 injectors and went from 2 per cylinder to 1 per cylinder to get around the problem you are facing. The old injectors are already at the limit and raise the risk considerably in high boost situations.

On the 2.9L block at stock compression (7.1:1), we got 625 whp @ 1.5 bar (21 psi) on pump gas (93 octane US = 97 RON). If you are already getting 600 whp at 0.7 bar (10 psi), you have a monster motor on your hands. Are you running pump gas or race gas?
