1966 Mk1 cortina GT She Drives!

5 minute(s) of a 319 minute read

With the bodywork taking a lifetime I've been looking at superchargers - I wrote my dissertation on this years ago, it's all theory but the practical side needs to be worked out.

I managed to find a bad ebay listing so figured I'd take the plunge!

It's not far off being the right length and the current idea would be run it as a draw through setup as going blow through would ideally be a full injection setup.

I think I'll need to fabricate a new inlet manifold and pulleys but itll be a fun project and one that I'll take lightly. Plus boost and whining noises

I'd not looked at pintos with them, I've been doing some research over the last few weeks and this a quick breakdown of what I'd like to do.

Using the 1590 that I've got:

•drop the static CR to 8.5:1 min 8
would be better

•run the boost to 7psi approx (I'll work this out - thr dissertation was 10 to 12 psi which is too high for now)

•find a lucas distributor that I can play with and lock the advance off (still researching this)

Draw through setups

Weber 28/36 DCD

Pros:

•There's jets and tuning parts
•I have spares

Cons
•weighty when hanging off the back of a blower - they crack inlet manifold as they are! Ford had to add supports to the manifold
•height I think itll be too close to the bonnet but to be confirmed

SU's

Pros
•they work!
•not a complicated carb

Cons
•I don't know a lot about them!

Fazer 600s

I know it's a weber but hear me out! I bought 2 sets of fazer 600 carbs for the cortina years ago but never progressed far from making a basic manifold. It's a CV carb like the SU so I'd use these and they have a 34mm choke like a weber dcoe 40 would have

Pros
•they were cheap and gathering dust
•small and can be mounted anywhere

Cons
•more head scratching to get them running
•I know little about them other than basic information I found for them being used on a crossflow

Blow through

Weber 28/36

They leak from the throttle shafts as standard! But the 32/36 has been used on blow through setups in Australia

From what I've read so far I'd need to change the float to plastic from brass, Bush the shafts along with end seals, runs pilot tube above the throttle to the shaft to stop it blowing out, pressurise the fuel bowl to make sure fuel comes through as it should under boost and change the gasket to neoprene bug I'll CAD some up and get a local firm to cut these

It wouldn't need anything modifying for inlets or throttle linkage and I have some spares but not enough to build a carb but given the modifications I'm not writing off a serviceable carb

Su/ renault 5

They work and can take power as far as my research has shown but they're few and far between which Jack's the price up! Given the prices I've seen off expired ebay listings I'd sack carbs off and build a speeduino ecu.

SUs would need an elbow to work with the GT manifold which is more fab work than the renault 5 solex which is an adaptor plate

Fazer 600s - i don't see the point in fitting itbs with a blower. Unless they're the lotus dhla dellortos but I'm not snoop dogg - I cant make it rain dollar bills!

Out of these ideas the 2 taht stand out are the fazer draw through and the weber blow through


I'm excited about the challenge as it's been 10 years since I started writing the dissertation and it's fun for me as I'm an engineer!

Allard did it back in the day and even built a 1650cc methanol powered anglia making 220 brake back in the 60s!

Here's an anglia to finish off my rambling!
