Innovate Motorsports wideband O2 system installed! Question about 6bbl intake

[biomedtechguy]

I have the gauge that shows both O2 sensor readings in real time as A/F ratio or Lambda. Since I have the Edelbrock/Chrysler aluminum 6 bbl intake, which side of the intake feeds which side of the engine? Does the intake cross over or do the carburetors mainly feed the same side of the engine the venturi is on?
Or is it pretty much a mix? Any difference in that equation for the center carb vs the outboard carbs?
Thanks

it is a duel plain intake witch is a uper and lower runners. this is for street ability with that said when you watch the air fuel ratio most gauges give you an avg number. the o2's is so fast unless you have 2 gage i.e. left and right make small changes to the fuel air ratio so you can get an avg, number be around 13.5 to 1. 14.1 is stoichiometric [ sorry i cant spell well ] witch is perfect hard to get stay around 13 to 1 at w.o.t . remember that a lower number is rich and a higher number is lean to lean and we get a piston b.b.q now if you had a 4 gas analyzer well that is the best tool for tuning a carb set up.

Thank you. The 1 gauge displays both sides simultaneously, in 2 separate displays within the 1 gauge.
I know it's a dual plane intake, but I don't know if the flow is mostly mixed, mostly across from one side of the carbs feeding the opposite side of the engine, or the same side of the engine.

look at a pic of the intake you will see that 1 hole is on the uper side and the second hole is on the lower so the front carb for instance the left side will feed no 1 cylinder on the hi side of intake and the lower will feed right side cylinder about to fire for the intake charge . might be cyl 4. haven't looked at the inside of that intake for a while. look down the carb ventures you can see which carbs feed witch plane hi or low.

It's an interesting tool...
The "lean spike" when the outboard carbs open was only something I read about. Now I see it! When I'm cruising on the center carb and stomp it, the AFR goes from around 13.5 to 20 for a second!
Not the time to, for instance, add a nitrous shot!

How do you like the Innovate wideband system?
Is it easy to use and do you really see the fine adjustments you make?

I have 2 one barrel carbs,the lean spike alarmed me at first also!.....LOL

I have one on my crossram hemi and love it really helped me tune for all phases of the car idle cruise and acceleration small changes in jet or idle mixture show up still making small changes. The crossram manifold each carb feeds one side not sure how the sixpack works.

I think that Hemirunner demonstrated the answer pretty well here:

It's a dual plane.
If I use it instead of the ModMan 6bbl intake, I would strongly consider having Wilson manifolds do a Vanke modification to it, as well as discussing with @IQ52 the "port runner roof raising" (IIRC) mod that Jim wrote about having done to a stroker RB 6bbl.

I am making a conscious effort to drive my car to local monthly car show venues, just about every Saturday through each month there is a local, casual event. The point being that I'm 57 and not getting younger, and I want to enjoy my car.
I bring this up because I have made ZERO adjustments to my timing or my carbs since I got the wideband O2 system installed, and that is mainly from not having time to do it.
A rich/lean condition at the O2 sensors could be affected by advancing/retarding the timing too, right? In other words, if the engine is under light throttle, like cruising along at 35-45 mph on the center carb, or at idle, more advance would cause more efficient/complete burning of fuel?? Conversely if it's a bit lean, a little less timing could help??
CERTAINLY my first focus is jet sizes for on the throttle/hammer down tuning, and all 3 carburetors idle mixture screws for idle engine RPMs.
I am sure the O2 sensor system is going to help, I just need time to WRENCH.

Here is one article that I used to set my carbs.
It's half way down the page.

Another good article.

and another good article by promax. I used there metering plates to make it easier to change jets on outboard carbs.

Have you driven the car with the new gauge?

 

[biomedtechguy]

I had the last 2 bookmarked already. Thanks

I have. See post #7 in this thread as an example of one of my observations:

I need some more seat time and wrench time. It's so freaking HOT and HUMID right now, cruising isn't as much fun as the spring and fall.

Made a few passes at SMR in 90* heat....Black firesuit in a black car
Went 6.3 in the 1/8

Yeah, but yours is a street driven, supercharged, Gen 2 HEMI
Honestly, I would like to spend more time driving and wrenching and tuning, and I am making a conscious effort to go to more local shows/events in my Roadrunner, because YOLO, and I'm not getting any younger, and some of my "car activities" are actually causing me some significant aches and pains, which I am concerned may get worse as time passes.
Until I get the front suspension system installed, and the Wilwood 4 wheel disc brake system installed (both are related from a "geographical" position in that the front suspension and front brakes are all in the same area of work) and the mechanic shop who has worked on my car (Dana gear swap) and did the 9" Quick Performance rear axle assembly swap in, and UMI suspension parts, and 4 wheel disc brake system on my wife's GTO is going to do all of that, I'm not going to the track...I would just get frustrated and I also want the car to be safer than it is for the speeds I get to at the track.
I will still need to get the triangulated rear suspension system installed to really get down at the track, and the hydraulic clutch and HitMaster launch control are something that I'd like to have too, but I don't know if I can stay away from the track that long.
