Bridgeport Carb.......Opinions
Hey guys just curious on some of your opinions. I was wondering what kind of carb set ups you Full Bridgeport guys are running. Anybody with any experience from previous set ups feel free to chime in. I'm looking into some carb set ups for my Bridgeport build so I'm looking at things like tune-ability, drive-ability, boost friendly(eventually will go turbo). I have one in mind but I want to see some opinions and creative thinking and here what you guys have to say. Discuss

overall, i feel your best choice is a Weber - IDA if you're going to keep it N/A (god, help you if you need to drive in the winter 
) and DCOE if you plan to turbocharge. nothing less than 48 to 50 on with either style.
all the bridges i've ever worked with (a whopping 3!) were Holley-powered and they ran okay, but the Weber ones i've seen (i didn't work on them) seemed to run better. furthermore, i think you'll have much better support with a Weber.

ive got a full bridgeport and i use a 12a 4 barrell niki carb with bigger jets in it with mechcanical secondarys and it goes hard, love the sound of the secondarys opening up! otherwise i would buy a 48 ml weber ida or a 51 ml ida.

I have used both the 51 IDA and the Holley 650 DP carb on my full J bridged motors and I had better 1/4 mile times with the Holley. My powerband with the Holley came on around 7000 rpm's to 9800 rpm's.
The 51 IDA had a better lower end response and the powerband kicked in around 6400 rpm's to 9300 rpm's. I also prefer the Holley setup running NOS. Either way; I had alot of fun with both.

What does everyone think of just a standard Holley 600? I can find one cheap. I like finding good stuff cheap. How did you guys like tuning the Holley? Weber guys? I had a weber on my 20R motor and I honestly wasn't impressed with it. Didn't seem like it wanted to tune worth a damn

standard Holley? be very careful and know what you're considering. there are certain things that MUST be done to get a Holley to play nice with a rotary. personally, i like them on the street, perhaps it's because they behave like the Nikki - just amped!!! however, i think tuning Webers is so much easier. Weber on a 20R is worlds apart from a Weber on a rotary. hell, even a jacked up 20R is a slight bore (in my opinion) - not really to be compared to a rotary here. did you have any headwork on your former 20R?

I will be running my OER 45 on my bridgie. It may be a wee undercarburetored, but I cannot justify spending 500$+ for a new 48 carb and manifold, just to squeeze 10 more horses. I will be running the same carb for a small turbo, so its not like it will not get enough air.

Im currently working on a TII bridgeported block with a fully modified 51 IDA. Cant give any any tuning tips as it is in break in period. However, I can tell you that with 80 idle jet and 46 venturies, this ****** hawls ***. Im able to drop the idle down to 1,000. Well, thats all for now. I stil got about 700 miles to go before I can really punch it hard.

I wanted to see what kind of opinions I got here. Eventually I will talk with Robert and see his opinion on it. I just don't want to be spending alot of money on a carb set up that's only going to be good for the break in period then useless for any power when I can find something cheaper that is capable of of maing the power I want. I want to be able to have this motor back in the car and running next summer so the cheaper the better. If I have to I'll just use the stock Nikki for break in until I can afford the set up I would like

You want my real opinion: Buy a 48IDA . You can get away with just a 48 IDA with larger venturies and such. you can use it too on other application such as streetport and stock inlcuding P-Port. Its a one time investment period
anyone else wanna get into deeper discussion?

What application are you setting up for? 1/4 mile, auto x, road racing circuit....???
Holley carb all the way!!! JMO. I love them 4 barrels.
Hey wacky???/ What's a 48 IDA? You meant 62.5 right? 
they all work good when properly modded & tuned.

The car will be set up for, Drag, Autocross, Road course, and possibly Gymkhana. The car will be broken in N/A and then mated with a hybrid HT-18 turbo pushing 18psi. I want something that's going to be boost friendly obviously but not going to be overbearing in N/A form. I love hearing the opinions and more are certainly welcome. I guess I'm being lazy and want a carb I can put on and run great N/A and put all the turbo stuff on and not have to re-jet it. Also, what are your guys' thought's on an RB Bridge intake vs. a stripped down Nikki intake that's ported?

Dont just slap on an over-the-counter item and say its good coz they said it is good.
My own definition of tuning is to know what is best for your engine and driving habit. If you cant change or play with different jets and venturies, then you its a half-*** job. Tuning is not a simple task.

If you're gonna go turbo, than check with Robert at Rotaryshack (680rwhp) and get a side draft setup for turbo and use it n/a until you are ready to turbo. Holley/edelbrock etc take modifications to work properly, I'm gonna learn the hard way about this with mine.
