38dgas

[Guest John Walton]

Does anyone have any idea what size jets I should be using in my 38 DGAS.

This in a 2ltr Pinto with a Piper 285 Cam' ??

Mains? Airs? Idle? Pump?

[Peter Bell]

John, I have 140 mains, 50 idles with the screws almost right in and not sure about the air possibly 185. I have a 285 and flowed head. These settings are about the best I can get fiddling about but a rolling road would be best.

Hiya John,

I run a 2.0, FR32 cam & big inlet valve head.

I had a DGAS set up on a rolling road & the final sizes were...

 

2B settings 2.3 V6 settings 3.0 GT Capri

Main 155 135 145

Air corrector 185 185 185

Emulsion tube f50 f50 f50

pump jet 70 55 70

needle valve 2.5 ?? 2.5

idle jet 45 50 45

 

For lower states of tune, I'd come down on the main jet say 142 or 145

These may not be perfect, but they'll get you up & running.

Thanks for the info chaps, I'll give it a go.

One more thing to add to my things to do list

Does the DGAS bolt directly onto a standard DGAV pinto manifold?

[Guest John Walton]

Hi Geoff,

 

No problem fitting the DGAS, it goes strait on.

Now you can have the fun of guessing what jets to use

[Guest JWezley]

Hi Guys,

Just read this thread and was wonderign what is a DGAS and why would i wnt one.

[Longboarder]

Its a twin choke weber carb thats good for power outputs up to about 150BHP on the standard manifold with good fuel economy and easy fitting. Recognise it by the quadrant gears on the butterfly spindles.

Where do I get one from?

[Guest John Walton]

Hi Guy,

 

finding a DGAS/DGMS is not that simple.

I think they came off 3 litre capris and granadas and it will tke some time to find one. That being said you may find one in the first scrap yard you try.

They are available new.

Southern Carbs and injection would get you one. 0208 540 2723

If you are oop north you could try Bert Houldings. 01772 254971 but houldings will order from Southern Carbs anyway

[Big Jim]

Bert Houldings are closed, finished, retired, gone, as from this week I think, although we do have the phone number of "Andy" who was their engineer for tuning purposes.

Hi,

New ones are bloody expensive, I got a quote from carbs Uk and they wanted £285 plus vat, I managed to get a Pierburg version from a 3.0l capri off ebay for 35 Squidlies, Don't know if it works or owt as I'm going with standard 2.0l for SVA to keep the noise down. Theory being more fuel in, more energy dispersion and more noise.

 

My tuppenth worth.
