Weber 48IDA on Stockport 12a
Ok, so looking at RacingBeat's recommendations for the 48IDA setup, it should not be bolted to a 12a stockport. The "lowest" it can be bolted to is a 12a StreetPort.
Venturi: 37mm
Fuel Jet: 170
Air Jet: 150
E-Tube: F-11
Needle Valve: 250
I know it would probably not work with a stockport (and will probably end up with SP jetting) but what would be "comparable" jetting for a stock port?

see if you can find the jetting specs for the dellorto dhla 48mm they sold. I had this on my stock 12a wit hr.b jetting and it did great hell it helped out my mpg even. then after i built my large street port 12a i just rejetted it and blam. I had a a/f meter and if i ran the stock port jetting it would run lean on the higher rpms but did fine under normal driving. i even kept them in a ziplock bag in the glovebox so i could rejet when i was going on a long trip.... mpgs. I was getting over 20mpg on the stock jetting and around 12mpg with the jetting i had for the street port.

I'll let you guys know what jets he has, for searching things.

a good starting point:
40 venturies
150 air
200 main
65 main jet
be sure to ditch the filter @ IDA's inlet.
Too bad, I couldnt find the video when my bro's SA went heads up with a S2000 on the freeway. This with a stock 12-A, 48 IDA and dual exhaust (used a stock motor after he blew the 12-A monster streetport).

Yes he is..and drill out the inlet to the fuel bowl....am running a 48 IDA on a large SP 12A and it is way too much fun....getting shitty mileage atm, but after I change the jets, it will easily get 200+ miles on a full tank, depending on your right foot....
#9
I assume you mean to enlarge the passage in the carb where the fuel gets into the bowl? Wouldn't I need a larger needle?
PS: Currently rockin out on 400+ miles a tank if I can keep out of it
#10
400 a tank, Jeezus is right! porting = yummy fuel.
But yes, under the screen, the tapered hole can be bored out....needle doesn't NEED to be swapped on stockorts, but I recommend a #300 needle. Not a fan of Grossejets...

Your comparing sidedraft to downdraft. Different beasts but the Dell is a 48mm carb. Bolts to the same flange as weber DCOE.
Go to this link to see what the jetting for stockport and SP 12as are for Dells gruntled.
Maybe you get that IDA on your stockport and you can keep up with me on the next meet

I'm no expert but wouldn't a 48 ida be huge for a stockport 12a? Unless you run smaller jets etc... I only thought you'd run an ida on an extend port or above? People over here just run jetted nikki's/ 4 barrels on the smaller ports.

f-11 is great for stock port driveability adn good gasmileage, but it will cause transition problems especially on a stock port 12a. you'll get good gas mileage, but you're going to have a lean stumble at 3000 rpm cruise. If you want to get rid of the cruise stumble you will have to degraded gasmileage.
#25
Also, I do not want the 3000 rpm stumble, so if I lose a mile or two a gallon that is fine. After F11 the next rich e-tube is the F7, correct?
I am sooo ready to order this stuff and get her on!
