twin 40s

[FlashCadillac]

so... we're talking carbs now therefore you are talking to a complete novice

 

 

twin 40s on a 1300 Xflow? yes/no?

 

i need a new carb and was looking for a twin choke webber but saw some twin 40s

 

how much should they cost? and how easy to re jet?

hmm you say that but i hear they can fetch 20 + to the gallon if tuned properly! thats just what i hear though...

it depends on what state of tune your engine is, if it was a balls out rally spec lump then 40's for sure, standard lump then the downdraft is probably best.

 

I ran a group A Irmscher 1300 Nova in the early 90's on twin 40's, 102 brake at the wheels & would still do 30mpg, I used it daily without any hassles so it can be done unless you have lead boots.

my car does about 30/35 now

overkill unless full race

 

twin choke is best

its one of them things i have outside my back door for the prefect

 

will try to get a pic tomorrow

basically its a manifold for a single 40, lynx is the manufacturer and its a proper period mod for xflows, normally about £100 for carb and manifold

one of these but without the 55 on it and for an OHV???

thats the kiddy

[tim]

or u can do somthing like this

 

which is basicly 2 halfs of twins 40/45 etc so your runnin 1 chock per 2 cylinders

[FlashCadillac]

buying the snazzy manifold looks easier??? but i guess they are quite rare???

 

 

so my next question is 40/45/50/55s?? i asume the bigger the number the more gas it saps??? singe 40 big enough for a 1300?

[Twinkle]

a single 40 will be fine m8

 

i got mine from gs escorts, someone else did offer me one after i got it but i cant remember who it was

[tim]

single 40 be fine for a xflow

I hope I'm not teaching to suck eggs but it's fuel to air ratio that matters not big carbs. Adding more fuel to a stock engine that doesn't breathe anymore air would simply flood it.

 

twin 40's are a carb method to fuel each cylinder individually and provide enough fuel for a race engine that takes in a lot of air because they are built to rev high. a single 40 is an intermediate step. a twin choke is a moderate street mod. some mild 1600 xflows use these like the mex and XR2. so a twin choke on a stock 1300 would be more than ample. they are probably the cheapest mod to go for also.

 

hope this helps
