38 DGAS on an XE ?

Anyone ever tried it? Ive googled it to death but cant find one photo.
My initial plan was to very simply make a weber flange for a standard XE manifold and weld it on, however looking at it again, the downward shape of the manifold is a little concerning with a carb setup?
I know in theory the air and fuel should be well atomised, but its a lot heavier than the air only it was designed to suck up there in the first place.
I can’t afford a splits setup, so this seems the best option for a few events I want to do over here that enforce the two choke rule, simply swap it over and swap it back.
Anyone any comment good bad or indifferent on an XE on a DGAS?

i know someone that did he made a bolt on adapter plate, dunno if was any good, he works part time next door, so if i see him..............

cool thanks Graham, yeah same idea bolt on adapter plate would be fine too, its the only cheap(ish) and easy way round although 38 DGAS seen to vary greatly in price! i might put up a wanted add here see if anyone has one knocking about

although those twists and turns in the inlet manifold cant be good but, it will still be a far better shape manifolds on v8 stages, rover v8s and many many 50's,60's and 70's cars

What about using the original injectors and use the 38 dgas as a throttle body as such? If you have an ecu already fitted to do so.

I don't John I'm only running a megajolt so no option for running fuelling as it is. I can run 4 chokes on 90% of the events I do so it has to be easy to swap over, I don't mind a drop in power once it runs well.

Does port spAcing anywhere near match xf or pinto ?
If so use ford (or other ) twinchoke manifold with an adapter plate. If you look at my westfield thread I did it for xf on A Zetec

Bogg bros over here can make any sort of manifold
They do one for running split bike carbs apparently they run well

i mostly make stainless and inconel manifolds for historic race cars for a living, the manifold is definitely not the problem! :welding:
but also do aluminium too, so thats no problem, im just worried more so what will run the engine best more so.
i have a good few sets of spare bike carbs here that i use as jigs, i suppose i could try knock up a manifold and split a set and see how it goes.
im more worried about the drivability rather than the actual difficulty of fitting different setups.
they should really relook at this silly rule anyway, there is no 'grp4' rally cars going to enter road rallying these days, which is why it was originally enforced :dunno:

Oh yeah of course

Tbh I think you will get good drivability from either splits or a single carb
I'd avoid single forty etc as they seem to struggle
Im undecidable about the rules tbh
How many escorts are running pinto with splits on and getting very similar power figures to running twins

It would certainly be an advantage to me if they changed plus a lot of historic cars would become legal that came with twins from the factory


I currently use a single 40 for road rallies and I'm still battling with it
I have good drivability and power out of it now but it has taken ALOT of messing about

I also have a manifold for twins to go on for any events I can run them and switch back an forwars

But hang on won't you still fall foul of the rules
I thought only 8 valve cars came under the two choke rule
Whereas all 16v engines had to run standard injection

Sounds more like my memory also

Splits are just to let the wealthy have an advantage.
Single carb two chokes max makes far more sense
It was originally to limit power.

Yeah I never actually ran a single dcoe on a 4 port engine (A and B series yes) but I've heard it's a nightmare to get a bad midrange flat spot out, same with pintos. Wonder would a single IDF work? Would a dgv be too small for a stock xe?

Yes you guys are exactly right for road rallies, but our events aren't strictly exact road rallies with no competitive road sections, thryre targa rallies. they generally go by the 'main' rules, but have alot more flexibility, and don't distinguish between that once the rest of your car falls into place . Thry are strict on full interiors, stickers, bumpers, and to a lesser extent hydro handbrakes. I've never actually tried to enter with my current setup yet, and I know 3 or more guys that are running twin 40's and nothing has been said to them (yet) but I'm just planning for the worst case scenario

So ive done a good bit of reading last night and research into the Chinese (apparently weber licenced, but I’m not entirely convinced) EMPI HPMX copies of Weber IDF’s.
I laughed at the start when I first read it, but to my amazement, there actually appears to be some very good reports from reputable people using them, especially on historic alfa race cars.
Id be as sceptical as anyone else with Chinese sh!te, but these appear to have some basis.
For the price, it’s hard to not want to try it

Looks interesting
How much to make a xflow manifold?
