fuel slosh in pressurized carb

[kirkallen143]

I have a question:
when carb is pressurized will fuel slosh be the same, more or less? I plan on additions such as extended jets and what ever else there is, but just wondering since I tend to use my bronco off road. Thanks for any info.

Kirk,
I believe fuel slosh will be the same. We haven't noticed any difference anyway. The only problem we've had is that the fuel does lift the float under hard acceleration thereby shutting off the fuel flow. So we went to a circle track float that has a beveled portion that will allow the float to drop when the fuel sloshes toward the rear of the car.
All of the above is assuming that you have a sideways mounted (float bowl facing the shock tower/inner fender) Holley like we do.
If you're 4 wheelin' then this might be a good idea. Also make sure the float is a solid Nitrofyle (sp?) style.
Later,
Will

Thank you for the reply, and I believe you have something there with the circle track float, it just might work for the best. "You are a gentleman and a scholar, and I will dance at your next wedding."

No problem!

Will,
Have you ever looked into the "Circle Track" carb that Holley offers? They have no choke mechanism, the choke rod holes have been sealed, the throttle shaft has been metal cupped sealed on one side, etc...
Basically sounds like what you have done to your carb, or close. I believe they call it the "Kieth Dorton" series. Might be something to check out even though it is probably 3 times the price.

Cool I'll check that out!
But I bet it's a bunch more than three times the price! We've got around $65 into our carb.

Kelly's Falcon is by far the cheapest mid. 12 sec. car I've ever seen!

Just to let y'all know, Moroso puts out a anti-fuel slosh kit for the holley. It is about $50.00 and adds about 40% more volume to the bowl area. It is intended to be used with the jet extensions and notched float and includes fuel cell foam to knock down on the slosh. If it works, I do not know, have asked around and nobody could tell me either. Might have to find out one day.

My goodness you Americans are lucky!

The way we mount Holleys on Aussie engines is different.

Because you Americans run log heads, there is no space to mount the carb perpendicular to the crank centreline and still actuate the accelerator linkage.

This allows the power valve and one of the main jets to be exposed under very hard (almost 1 g) launches. The old Lemans style float bowl and jet inlet extensions help.



It really doesn't matter, you guys don't have corners like we do.
