Carby choices

So how is economy on a 45dcoe compared to twin 40's? Something i have to look at soon, my car just blew it's head gasket and i gotta get the next motor in.....that motor came at just the right time

I have heard a few reports that the twins are more efficient. I don't really know of anyone that has a single with a Lynx manifold that works properly. No3 always runs rich.

its because the lynx manifold has a weird firing pattern, the dissi needs to be modified i believe

I reckon it would be more of a case with the brake booster vacuum signal upsetting both #3 & #4 cyl's off #4. These manifold's are grouped as pair's eg. 1 & 2, 3 & 4 so 1 & 2 are basically on there own & are fine.

You have to run the passenger side (3 & 4) mixture richer to even out for the brake booster vacuum signal on #4 the catch 22 is that #3 run's richer than the rest.

With twin carb's you can tune out the descrepancy in #4. I've had to do this on my 2L excort with twin 40 dell's.

you'de need to do a lot more to change the firing order mate

but no, it not necessary to do that - mollins setup seems to run just fine with his dcoe on lynx.

got a TS manifold today (cheers loon ) so on the lookout for a dgav now.

I'm guessing that a TS Passat manifold and a DGAV from a Cortina just bolt straight on to one another or is there a need for an adapter plate?

That's right they were made for each other! No need for an adaptor plate.

There is an adaptor that will allow the DGAV to go on a standard 1600 manifold, it's basically a funnel. I doubt performance would be fantastic.

Excellent.. All I need to do is get a TS Manifold and steal the DGAV from my girlfirends RS2000 mwahaha Haha, Can anyone tell me what the performance is like with a Dgav setup on a 1600?

[gldgti]

might be able to in a couple of weeks ()

Excellent.. Keep me posted.. i'm keen to try the set-up myself
