Sideways mounted carb

Post by psychomotors » Tue Jun 12, 2018 7:52 am

Maybe a dumb question but what would be the benefit? I have seen a very few cars that were drag raced set up this way. I can't remember which type , but I'm thinking double pumpers and in a single carb situation. Thanks.

Sideways carbs are pretty common on tunnel rams.
Had a Super Stock Cleveland with a ported Strip Dominator which made more power with the throttle plates partially closed. Tried mounting the carburetor sideways to see if it would help.

Brasswell is big on mounting single carbs on cast single carb intakes sideways. I know a couple guys who have used their carbs, mounted sideways, and it didn't make a difference. One lost performance, but to be fair, he went from a pro systems sv1 on q16, to the smaller CFM brasswell, mounted sideways on c14. And he couldn't understand why. #-o. They actually told him it should be faster.

The main reason you see a pair double pumpers mounted sideways on a tunnel ram is on some motors they won't fit mounted front to back and on the rest it provides easier access to the float bowls for jet changes

YES ...

The original intent of mounting a Holley sideways was that it became a lot easier for changing jets at the track.

Then fuel control with a side hung float became a plus in some situations.

Most of the time it will require nearly "one to one" throttle opening unless the carb is spaced really high.

Yeah, I get that too. That's why I asked about a single carb installation. Thanks guys , still clear as mud. :lol:
