Hi,

I am looking at motorising the bonnet vents/flaps on the Sag and was sure someone on here had done it already but I can't find the info.

So, has anyone done this and could save me re-inventing the wheel ?

I know TVR didn't bother as it kept cooking the motor which, for some reason, they put in the hottest place in the engine bay. I'm sure it's possible by moving the motor elsewhere.
Just considering the various options at the moment.

Any info/suggestions very much appreciated.

Thanks Paul.

I was thinking of mounting the motor elsewhere and not on the service bonnet and using some kind of linkage to the flaps.

I'll see if I can track down who did it.

Strangely enough it was the LAM3 actuator I was looking at.

Only problem is it's rated at upto 60C, it's got to get hotter than that mounted above the manifold hasn't it ?

Did think of indvidual motors (small) on each flap with worm drive.

Also got to ensure the bonnet can be opened if the motor fails.

Lots to think about and experiment with.

Wasn't at all sure of the kind of pressures that would be on the flaps.

I've just undone the existing retaing bolt on the lower flap to see what it looks like when closed.

The seperator between the top/bottom flaps is arched, unfortunately the lower flap isn't (or is but not as much) and you get a step between the flap and the service bonnet at the top and it looks rubbish !

Looked at the LAM3 actuator, struggling to find a uk supplier. Current price is £191 + delivery.

Looking for cheaper alternative or way of doing it.

I've never used pneumatics at all so wouldn't have a clue what I'm looking for or what I'd need.
Any pointers ? I didn't get far with finding info on your Saab suggestion above.
