How many points are carburetors?

My 72, 914, has been converted to carburetors?

How many points is that for AX?

I’ve been told both 4 and 8.

Thanks, Chris

The answer can be found here on the rules page which links to the Zone 8 rules page.

F. Induction system modification:
1. Electronic or CIS to carbs/mechanical injection 4-points
2. Venturis or fuel distributor/controller other than original 4-points

The 8-point rule was revised in previous years.

I guess I should have been a little more specific the first time, my fault.

I need some clarification on F.2 Venturis or fuel distributor/controller other than original 4-points. What exactly do they mean here?

Thanks!

It doesn't apply to your car.
You take 4-points for switching from electronic to carburetors.
If you had a 69-911T with 27mm carburetor venturis and installed 34mm venturis for increased air flow you would take 4-points.

Fuel distributor change is for CIS cars that install a high flow rate unit.
Controller is any modification to an electronic fuel injection computer, such as a chip in a motronic car.

If you take 4-points for the Weber's you put on (with 28mm venturis and you installed 34mm units you don't take the additional points; 4 is the maximum.

Thanks! That's what I needed to know.

"Controller is any modification to an electronic fuel injection computer, such as a chip in a motronic car. "

Steve,
I had always assumed that aftermarket chips on a non-turbo car were free. Apparently they are 4 points.
Is this new or has it always been that way.

Thomas the rule has gone back and forth over the years.
4-points is how she reads for 07...

Turbo cars can have a 4-point chip if boost is stock, increase boost and it is 7-points.
