Just wanted to know if the Weber 48 IDA is too much for a stock port 12A. Any info would be great. Thanks guys!

nope! it will just all depend on the jetting. PM wackyracer since he owns a 48 IDA atop of the 12a

I had it, and it works BEAUTIFULLY.

the only problem I had was getting an air filter in there. K &N makes one that will fit, but get the shortest one you can... otherwise the hood won't close.


BTW...here's the jetting I used on a stock port:
Air jets: 135
Fuel (aka "Main") jets: 180
emulsion tube: F11
Needle seat: 3mm
Venturi: 40mm

Fuel pressure: 2.75psi
Fuel pump: Holley Blue

It ran rich as hell down low (idle-2500), but above 2500, the a/f ratio smoothed out, and was dead on the rest of the powerband. Words of advice: IT'S THIRSTY. I averaged 12mpg on the hwy, and about 6-10 in town, depending on how much I got on it. (I love the way the RB Streetport exhaust sounds at WOT, and the carb is loud as hell too... so, your results may vary )


Hope that helps.

Thanks for the info Chef!

40mm venturis are probably a bit big for a stock port. I'd go with 38's.
