I've got at superjet with a 62t motor. I'm considering going with a single 44 intake setup for better fuel economy. So far I have only found two setups.
Blowsion (I think this setup is a joke. It's an adapter for a kawi 650 manifold)

ATP (This one seems nicer.)

I know dasa makes a manifold, but it's a bit out of my price range and I'm pretty sure it only uses v force reeds. Are there any other options out there? So far it looks like ATP is the best way to go.

I had an ATP with a single 48 Novi on my RN years ago and it ran awesome. If your looking for a lot of bottom end, that is the way to go.

I'm not too concerned about power. Just how far I can go on a tank. I'm
Hoping that a single 44 will burn less fuel than the stock 38s. I'm doing an endurance race, that's why I'm worried about fuel.

Hard to do better than dual 38s for fuel economy.

For the Hahn Race you cannot change the stock gas tank.

What he said.

I looked up the BCW setup and it's the same thing as Blowsion's setup. I can't seem to find a Riva manifold that is for a single carb. Sounds like ATP might be the best option.


Now I just need to decide if a single 44 will burn less fuel than dual 38s. On paper the single 44 would burn less fuel, but I could be wrong. Has anyone done a back to back comparison?

BCW is out of business. Riva manifold is discontinued > Blowsion.

You will have to test this stuff yourself. Most people have no idea what will work in a race that is about 5 hours long. Because this is a one time per year event I would just pit every 2 laps instead of 3 if needed.

I've just spent the last week fine tuning a set-up for the Hahn. It sure is nice being 10 minutes from the Lake.

I was told that I can get 3 laps out of a superjet with stock carbs, but that's cutting it pretty close. If a single 44 will burn I'd rather do that just for a piece of mind. I'd really hate to run out of fuel during the race.

Stock 38's are very fuel efficient. A single 44 and an ATP manifold may burn less gas but not sure if it will really make a difference. Thats something you may just have to try.

Won't a properly tuned engine use the same amount of fuel regardless of the number of carburetors?

If you wanted to use less fuel could you tune it more lean?....
