New idea for mounting Weber carb

[Anonymous]

The DCOE comes in sizes big enough to feed most any 200, why not attach tubes near ports 2 and 5 that curve up over the valve cover and mount the big Weber up there. I really like the idea of just tuning one carb. The original carb mount would get a cover plate.
Any idears on how big a DCOE a 150 hp six would need?

Well, lessee....off the top of my head...... You need about .5 lbs of fuel per horsepower per hour so 150 hp is 75 lbs an hour and the fuel air ratio needs to be about 13:1 on average so you need 975 lbs of air every hour or 16.25 lbs every minute which is 260oz and at about 70 F air weighs about 1.19 oz/cubic foot so you need about 218.455 cfm to support 150 hp..............but that's just a guess......

Keeping the fuel in suspension would be the challenge. 48mm DHLA carb might be "cheap" and cheerful.

At the 34 mm venturi mark, DCOE 40, 42 AND 45 carbs can flow about 180 cfm per barrel, so its a 360 cfm carb at 1.5"Hg. It works okay, and you'd get up to 200 hp or so if the manifold was good. In idependant runner specs, three carbs could flow 1080 cfm technically at 1.5"Hg, but independent runners have next to now fuel suspension drop-out and a re very, very good at atomising the fuel air mix.

In Australia, form the start of the six banger power wars in the 60's, GM Holden 179 cube engines could be had with an aftermarket DCOE 45 or DHLA 48 intake from Lynx. Quite a good set up, even if the porting to the siameshed port head was a little 'odd'. I think those little engines used to almost hit the 200 hp mark without too much trouble.

Sounds like another good idea. Just watch out for the spring tower!

Humm, those spring towers are kinda short in a fox body.

Then have yourself some fun! It's a great idea!
