Dual Dawes Setup

I am about to connect the plumbing for my Dawes setup. I need confirmation that:

1) The hose from the air filter Resonator connects directly to the needle valve
2) The three ports in the Vacuum solenoid are blocked off

It LOOKS simple, but given the work to get this far, I would hate to screw up.

Thanks in advance

Have you googled Chaz Yellowfoot for his drawings, very well written as well.
Hard to stuff up, that vacuum solenoid I think I looped to ports together the third went into the air cleaner box
seems so long ago now Boots did mine

Yes, I have Chaz' write-up, and yes it looks straight forward--just a final check before I disable existing stuff.

1 is yes and 2 is also yes.

whats the reason for the dual dawes set up, I cant see the logic in it tbh.
Maybe Rumjas can fill me in

Hi boost equates to higher fuel consumption pretty much. So having two max boost options I suppose you can keep your fuel consumption down.
But it all depends on how you drive your car.
Me. I tend to be hard on the pedal most times so for me it would be a waste to do it. But having said that if I had the time I would fit one up just to see the difference.

Still cant see the point but thanks,

Each to their own John.:D

According to Chaz 'write up and recent email correspondence, if I set low boost around 14 psi and high boost around 17 psi, I SHOULD get reasonable economy around town, and plenty of GO with heavy throttle. That setup also (according to Chaz) keeps EGT at sensible levels.
It also prevents boost above set levels, and the factory setup can get really high boost on occasions.
Worst case: it does not perform as documented, and I just reconnect the original set-up or just run a single Dawes to limit boost.
All good fun.:clownredpuff:

So you would use the lower value boost if touring for example.
TBH never thought high boost meant high fuel consumption.
anything to save on fuel has to be a good thing eh,
Do you know your fuel figures now for comparison?
