Sniper might work well if it's installed correctly just like a MS system.
How fast is the injector control time on a modern port injection system? It had me wondering if there is enough control to do a port injection on a single port engine with the injector only firing while each valve was open. There would be only 2 injectors. One side would fire twice, then the other side twice. With a slight percent shift for cylinder filling differences. It would be an interesting academic issue, not necessarily of much practical value.

Putting TBI is as worse as putting progressive carb on bug engine.

It will never work perfectly.

You have to be willing to stretch beyond all the naysayers who have NEVER even tried it but think because they have fought carbs for 30 years, are either too scared to try, or too ignorant to want to. Mine fires right up EVERY time. runs a closed loop system and runs learning mode all the time so it is always changing just like temps and atmospheric pressures do. I used an old weber manifold and a $15 Holley adaptor, no heat risers, and haven't had any issues with it. I stopped coming here very often because of how many purists cant figure out how they got both legs in one side of the panties, and now are too proud to admit they don't/can't figure it out. for those who are even semi curious. And can afford it, do yourself a HUGE favor. Invest in EFI. I absolutely LOVE the Sniper set up, and will NEVER go back carb.

Thats an awesome setup you have there. Any more info about the holley adaptor or the air cleaner? Great job!

How close to bolt-on, self tune, & drive away is this setup. I’m interested in any headaches you’ve had to overcome if any to get to the point you’re at.

Here is my super sniper 2300 on my 2 liter. Running the progressive intake. I would like one with more of Y on the bottom instead of T. Also opened up the end castings. Runs strong. Working on anohter one for my bus.

I am interested in seeing your intake with the carb mounted like you have in the pic a couple pics above. What intake are you using?

I used to buy a lot of jets and had fun trying them out. Now with the sniper and my laptop, I can try different configs and then review them on datalogs. Its fun learning about efi and what you can do with AFR, startup enrichment, acel enrichment. You can dial in idle, cruise, adn wot. Also has the handheld screen with customization gauges. This is basic system but pretty impressed with what you can do with it. I need to post pic of datalog and all the different settings you can review and compare, its endless.

I think I'd prefer one of these Solex pattern throttle bodies for TBI applications. I haven't got a problem with wiring in an ECU and a lot of the issues of the Holley TB setup are resolved.
This is a dyno set up so excuse all the messyness of the install

Paul , is that just one injector feeding that engine ?

Yes just one 630cc injector

Love the setup! New here but not to the VW world. Was curious if you might be able to help out on the setup i have going on in my Ghia. I just cant seem to get the tuning right on it. It idles and drives but when i go to stab at the throttle it cuts out. also running very rich. debating on starting over from scratch but if you have some tips thatd be awesome! I cant PM yet as a new user so figured id ask here!

Good looking setup. Have you done a datalog and see what is happening when you stab it? Going lean or too much fuel? How does your acceleration enrichment look?
Are you using timing control? I am in process of doing that now.

Send me a PM when you can.

I used EFI pros to help with my tune and its spot on. It worth the spending the money, Chris really knows how to tune.

Ill definitely give them a shot. according to the handheld its leaning out. Havent done a log yet on it was trying to remedy and have it learn before that. it was my next step just ran outta day light and time to get the car back out on the road. Idle spark is enabled yes. and acel enrich is gradual curve from 0.0 to 57.7 (havent touched this yet). I think it says 24 hours for PM ability

So much of VW lore is based on what happens in LA. / Southern California coastal areas.

Where it is never really cold , ( although back in the 90's when I was there for work in Sunnyvale it was 30 degrees... ) and usually centre mount carburettors dont need extra heat. So anything similar works well there too.

But try driving the same setup somewhere damp or cold and the story changes. So what runs well in EMPI's back yard judders and spits in London UK...

So " it works well " and. "It does not work well" depend a lot on where you are.

Automatically closed loop pouring extra fuel in to cover up a cold centre mount manifold will work too.
Just there are reasons why cost sensitive mass producers of vehicles use more expensive and complex multi point injection setups.
