Chaps,

Let me know what you think of this idea.

Planning twin turbos which will be mounted above each exhaust manifold.

As they'll be quite close to bonnet was thinking of some ventilation.

Got carried away and thought of boost operated bonnet vents.

As boost rises, pressure is fed via a one way valve to a small air reservoir, from there to a pneumatic ram (with spring return), opening vent.

As boost pressure drops the air reservoir carries on keeping vent open until return spring overcomes pressure (via a small bleed hole), thereby closing vent.

Cool huh

very creative!

So if the turbo is connected to the bonnet, how do you lift the bonnet?

Pete,

No, turbos connected to the pressure vessle and then to rams via plastic/rubber pipe. Will stick some dry breaks in line, so can be undone quickly.

Sounds a cool "gadget" but extra weight if I was to give my honest opinion....I'd just cut some vents and leave it at that if it were me.....Oli.

But as you come off of boost the turbo will be spanking hot, & then the vent closes.
Heat soak etc...

Suppose you could just make sure that its always on boost

Sounds like fun. I had a camaro with a cowl induction that opened up when you were at WOT. I always thought it was kind of silly but other people liked it .

Have a look at carb parts for cheap actuators. IE a vacuum choke pull off.
Another way to do it is using a thermistor. That way it's directly related to underhood temps. Again look at carbed engines that use a "Thermac air cleaner". Very common, very cheap and only a couple ounces of weight.
Cheers.
