Retro-gone. Posted July 18, 2008 Report Posted July 18, 2008 can anyone explain the dgas term to me? i know its carbs but unsure which, i keep getting told to fit a dgas this and that but ive had no explanation why or what they are fitted to, the only thing i know about ford carbs is the single downdraught and the twin weber, also does a twin weber automatically make a car quicker as apposed to the single ford downdraught? cheers.
60ftman Posted July 18, 2008 Report Posted July 18, 2008 DGAS is the twin-choke downdraft Weber as fitted to the V6 Essex engine where both of the butterflies open at the same time. 38 DGAS (fitted to the 3 litre V6) had two 38mm 'bores' and an automatic choke (I think the DGMS had manual choke, but I could be wrong!).
Retro-gone. Posted July 18, 2008 Author Report Posted July 18, 2008 ok thanks, so what were the standard twin choke weber carbs called, as fitted to 2.0 capris and cortina pintos?
razersedge Posted July 18, 2008 Report Posted July 18, 2008 32/26 DGAV?? i no it's just a typo but it's 32/36 is the standard 2.0 twin choke and it will say on the side of the base plate but there is another carb to keep an eye out for and that is the 40 dgav rare as rocking horse poo (i know because i have one and it cost me a small fortune), it's a old carb because it has covers over the gears on the side i think its off the rs3100 capri but i'm not sure. buy the way just in case you didn't know the numbers stand for the size of the outlet on the base of the carb so if you look at a 32 /36 they are slightly different sizes on a 38 or a 40 they are the same size and both chokes open together
Toby Posted July 18, 2008 Report Posted July 18, 2008 I remeber reading in a mag years ago that a twin choke 32/36 was better than a 38 dgas on a pinto, but a 38 dgas made most people think the car was faster as you get more throttle for any given foot movement. I do not speak from experience
glenbo Posted July 18, 2008 Report Posted July 18, 2008 IF YOU FIT A 38DGAS TO A PINTO YOU WILL NEED TO REJET IT MAINS JETS 145 AIR JETS 185 IDLE JETS 45 EMULSION TUBES F50 PUMP JET 45 THIS IS FOR A STANDARD PINTO
Toby Posted July 18, 2008 Report Posted July 18, 2008 IF YOU FIT A 38DGAS TO A PINTO YOU WILL NEED TO REJET ITMAINS JETS 145 AIR JETS 185 IDLE JETS 45 EMULSION TUBES F50 PUMP JET 45 THIS IS FOR A STANDARD PINTO How do you think it went? Did you go from a twin choke?
Copey Posted July 18, 2008 Report Posted July 18, 2008 32/26 DGAV?? i no it's just a typo but it's 32/36 is the standard 2.0 twin choke lol, should probably check before i post

Copey Posted July 19, 2008 Report Posted July 19, 2008 they do go a lot better than a 32/36, i changed from a 32/36 to a Dgas, made a hell of a difference!
flyingbanana Posted July 19, 2008 Report Posted July 19, 2008 i got 32/36 dgav on my xflow ...dont know if it was re jetted or not...but would that explain why it uses so much petrol ,if it was made for the pinto
RUSTYPUP Posted July 19, 2008 Report Posted July 19, 2008 My first mk2 Tina had a 2.1 pinto. I rejetted the twin choke and went racing at north weald. I changed the carb whilst there for a DGAS. My times were ever so slightly slower with the DGAS. I did notice one big difference............. loads less MPG with the DGAS
