I am cerious of the specs for a Mazdaracing 45dco, 48dco, and 50dco weber sidedraft carbs.


What is the pilot jets, emulsion tubes, main jets, air jets, pilot jets, accerator pump nozzles, outer venturis, inner venturis, etc, etc, etc?

Note: I don't care about the specs from IDA carbs so please don't bring that up.

 

Here's what i'm running... no guarantees its whats recommended but it's the kit I was sold and it works well on mine.

2x 40 Choke
2x F11 E.Tubes
2x 180 Main
2x 175 Air
2x 85 Pump
2x 60F9 Idle
1x 50 Pump/Ex.

p.s. this stuff aint cheap

 

THanks, does anyone have the specs of the 50DCO kit from MazdaRacing?

 

Wouldn't they sell the carbs with different specs for whatever porting you have?

 

talk to them.. i am sure that they will custom make you a kit with what ever specs will work best for your car..

what porting do you have, what size engine? if you have a stock port , then there is really no reason to go with a 50dco.

 

Nope, I have a bridgeport. IF I had a stock or mildport like before, I'd just stick with the Mikuni 44PHH I'm using.
I am aquiring a 55mm weber body carb with 50mm throttles like the ones sold from Mazdaracing. Only outside difference is I will need to machine my own metering oil jets and rod for the oil metering. I want to buy all the closest to right venturis, etc, jets, to get it to a starting point for tuning and go from there. I already got a reply from MazdaRacing. I just wanted to get someothers info on what they were using as their setup. Venturi size, main jets, air bleed jets, acc, nozzles, pilot jets, emulsion tubes, needle size, etc.

I am very aware of the best and adquate clause with different bore carbs, etc, etc, etc. I was just hoping to get some numbers on what they found to work best.
