These look great, would I be better off getting these or 44mm ones from wolf creek?  I'd love to have a set of triples and would like to build up an L28 possibly to 3.1L in the future.  I drive the car daily. 

 

All advice appreciated!

if your going 3.1 you would really want 45's

Hmmm, fuel would be a bit crazy but I guess if you want performance you have to pay the price.  Thanks mate.

If your concerned about fuel and it's a daily you might find you'll be running 16 or 17L per 100km with 3.1L on tripple 44's as I'm getting around 14L/100km on a L28 with 40's but not conerned as it's not a daily driver.

As someone running triple Mikuni's and beginning to get somewhat of a handle on them, I would suggest that if you were looking to race more than street then  go with 44's but 40's will still dump plenty of fuel to a 3.1 and remain both streetable and trackwise.

I think if you are going to do any sort of track work or build a bottom end capable of turning around 7-9000 rpm with a huge cam, then yes, chase up a set of 44-50mm carbs.. Around town or just for the "red light racing" 40mm will be just fine. Six throats versus two, six will always be better

[Glen]

Just a quick question working out flow rates of 40's and 45's. First whats the formula for working out the flow rate of 40mm carbs, and secondly how many variables are there in getting the correct flow rate.

 

cheers

To get in before the others.

 

How long is a piece of string?

That many variables huh, i thought it might be.

I remember finding a formula for working out CFM's for carbies....When I had my 40mm Dellorto's it worked out to around 1200 CFM! Sounds about right when you compare a Holley 1050 Dominator carb with only four huge throats compared to 6 40mm. I'm not sure if that was including the chokes though...

i found out that running the motor @ 90% efficiency and reving to 6500rpm the motor would require 473.958 CFM.
