60mm in the front window and 50mm is allowed in the roof for fueling as well unless you need the hole intruding into part of the roof and window to be able to refuel, then only the 60mm hole is permitted.

I just looked it up in the ROAR rule book and it says you can cut out 2/3 of the windshield, but I know that's wrong.

The windshield cooling hole cannot be more than 60mm in any direction. Best way to do that is a circle. 50mm is just a little bit smaller than 2 inches.

The refueling hole in the roof cannot be more that 30mm in any direction, and cannot intersect the windshield cooling hole (ie it has to be 2 distinct holes).

The rule was changed from 50mm to 60mm.
rule 6.1.13 on pg.28

Great information but the next question... What do you guys use to cut this out?? I'm looking for a trick or hot tip….

robert maestrey

you can use a hole saw attachment on a drill...or try a circle cutter.

WARDO

You know, this is just my opinion, but that rule makes no sense to me.I don't think IFMAR has that rule (maybe they do).But rules should keep things fair, when you can take a pair of sissors(or dremel)and improve performance,why have a rule against it? It's not like only a select few have sissors or a dremel.
But that is just my opinion. Don't they have enough to tech already?

You can either get a circle cutter (kinda looks like a protractor with an xacto blade), or I use a hole saw attached to my cordless drill.

you may find the handling of the car changes too with the hole at 60mm

but what is the new if it is new ruling on the side windows

ALG

I think you can intersect the hole on the windshield with the refuel hole, the only MUST is the the area must be the same 50% on the windshiel and 50% on the roof.
If the hole is 60mm diam. you can have a redius of 30mm on the roof and 300mm on the windshield.... or is this just ifmar?????

There is nothing in the rules indicating where the hole must be located. I think everyone believes 30mm is too small to bother with two holes and we all just use the 60mm for fuel directly above the tank.

6.1.13 Cooling holes: Bodies for on-road fuel-powered cars (other than touring vehicle bodies)
may have up to 1/3 of the windshield cut out. Bodies used on off-road fuel-powered cars
may have up to 1/2 the windshield cut out. For touring vehicle windshields, one cooling
opening is permitted, limited to a maximum of 60mm in any direction.
6.1.14 Refueling holes: A refueling hole is permitted in any body type for fuel-powered cars. The
following restrictions apply:
6.1.14.1 The hole must be centered directly above the fuel tank filler neck
6.1.14.3 For closed-roof bodies, such as Touring Car bodies, where the filler cap does not
extend above the body roofline when open, the hole may be a maximum of 30mm in any
direction, and may not intersect with any other hole in the body. Holes for use of the glow
igniter and carburetor tuning are allowed.
