is a 1.5inch su and a hiff44 carby the same? do they have the same size Mounting Flange?

No, the HIF44 has 4 mounting holes, the 1 1/s su has 2, carbs are completely different, the IF in HIF means internal float.

Doogie

Hay, it's not about the car, it's not about the venue, it's about the people that come here. Peter Dwyer, Mayor of Hay NSW.

Pretty sure the hif44 is 1 3/4in with a squareish mounting flange.

Why do you want one? What size is your motor?

thinking of setting up my stroked 998 to 1100 with the supercharger kit from Ben 92.

i was just looking at that one im gonna keep a eye on it.

The 44 in HIF44 is its size in millimetres.
It's less than half a mm from 1.75 inches.

yeah i just seen a 1 1/2 su and hope i could use that on the 1100 instead of the hif44 since im thinking about using it on a smaller engine instead of a 1275. it might work a bit better

an 1 1/2" SU can either be a HS4 or a HIF38 - the size is the same for these carbs - 1.5 inches, or 38mm - same thing

a 1 3/4" SU can either be a HS6, or a HIF44 - same again, 1.75" is 44mm

the mounting pattern for a HS6 is the same as a HIF44, they will mount to the same manifold

an 1100 with or without a supercharger will benefit from having a 1.75" carb fitted, doesn't matter whether it's a HS6 or a HIF44, as long as it has the needle to suit the engine, it will be superior to a 1.5" carb

ahhh ok thanks for this info.

If using Ben's SC12 supercharger kit, and HIF fits much better than an HS. You can fit and HS but you'll probably needs to get some spacers, I found some on a Rover 3500 that would work but found it was easier and looked cleaner just to use an HIF44.

I'd go the bigger HIF44 because 1, it's bigger and 2 if you want later on you can move the 'charger setup onto a 1275 quite well (with the correct needle fitted of course).

My HIF44 is actually from a Range Rover, although from what I've seen these had Stromberg carbies standard but there's possible a late model that had them. I also got an HIF44 from a motorbike off ebay. I used both to make a good one.
