Automatic bonnet vents
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

So if the turbo is connected to the bonnet, how do you lift the bonnet?
yours, Pete
I went into the RSPCA office the other day. It was so small you could hardly swing a cat in there.

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.
If your not living life on the edge you're taking up too much room!

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.

Paul,
Hence the reason for the pressure reservoir. I'm aiming for a litre or two of air with a pinprick hole so vent should stay open for a minute
after boost goes off.
As for weight, I can lose more than what it would "cost" on a day - ie no more than a couple of pound. Bicycle pumps only weigh a few
oz's
