weber 32/36 dgv carb info

should be good for up to about 140bhp, over that you can move up to the 3 litre capri non progressive version but they are quite dear now, better options for the money these days.

You can get a lot more than 140hp from them. The Brisca F2 boys use them and are getting 170+.

Yes, they are limited to the 32/36 - the 170+ bhp the top drivers get is true & you are right in that it's the carb that is the primary power restriction - you'd not see that on a road spec engine on a 32/36, these are fully built race engines built to rev like there is no tomorrow - same torque + more revs = more bhp, at sensible rpm, the bhp figure would be rather less.

The 3.0 Capri/Granada V6 Weber is the 38DGAS - about £50-60 on egay at the moment... If you put one of them on a 4 pot then be prepared to visit the pump a lot (been there, done that), they have synchronised throttles and will throw buckets of fuel in on part throttle VS a DGAV. The DGAV has fairly lean jetting on the primary (smaller) throttle which opens first, and richer jetting on the secondary (larger) which only starts to open at 1/2 throttle & more, so they give a good balance of power/economy - the DGAS doesn't, unless you fabricate or can buy a different throttle linkage?

There is also the DFV series of carbs which go up to 40 DFAV from the 3.0 scimitar and zodiac - currentl £60-90 on egay. Anything bigger that that and you are into the esoteric stuff & might as well buy performance carbs like the DCNF/DCOE's. The DFV is a good racing carb as it can be fitted with a vacum power enrichment circuit (like a continuous accelerator pump that operates on vacum demand) & was used in Formula Ford etc...

The jets etc... are interchangeable between DGAS, DGAV, DFAV etc... & I usually scavenge scrap carbs for bits to set other ones up!

My Zetec is running a 32/36 from a 2 litre. The Zetec is a 1800 130bhp standard unit apart from running megajolt. It rolling roaded at 139bhp. The carb still had to be jetted downwards as it was running far too rich. The same carb set up is now going on a 2 litre set up, again standard 136 cams plus the megajolt. It will be interesting to see what this comes out at when that is rolling roaded. I would have thought that as long as the carb can cope with the increased airflow then you will have no problem getting the hp dependant of course, on the engine its attached to.
The only reason the racing pinto mentioned earlier has all the cams etc is because they are are poor flowing head in standard form & they not allowed to do that much to them per the rules so have to increase the head breathing capability in other ways, plus the fact its 40 year old technology.

You can also get a progressive throttle kit for the DGAS as welll should you want to go that route. Cant remember where i saw it though.
