Turbo or supercharged 2Ts?

Not actually the case in F4.
The forced induction option is 2/3 capacity of the NA, 100cc versus 150cc.
For the watercooled 2T capacity limit of 100cc applying the same ratio would make 66cc, rounded up to 70cc.
In reality what's the likelihood of one being built, and raced, and winning or even getting close. Stop yakking about it, support the amendment and see what comes out of it.

I see the new rule changes are out.

F4 2T 55-110cc

and

Supercharged/Turbocharged 70cc 2T's

Ahh fuck
So the 22.1.3 is quite specific on crashing. The F4 rule is out to 110 not 107, for some reason but no dickhead changed the 24mm carb rule so it is pointless. Glad its not my concern anymore.

Appendix H – 125 Grand Prix/250 Mono
1.1 - All machines must be fitted with an integral lower fairing dam (belly pan) or separate catch tray which must be constructed and fitted to trap and hold engine oil and coolant with a capacity of not less than, four strokes = 3.5 litres or two strokes = 2.5 litres.

Why are they worried about the 2T 125 getting oil everywhere?

I see they have not removed the S

I see they never fixed the Carb wording for over 104 either.
A 70cc supercharged unlimited fuel system is interesting.

Yeah, forgot to Menton the s but i did during feedback through two different channels

It should save a few people some money on crankpins and or pistons anyway so its a good move with the 110cc.
You might be able to move that pin around a bit to stroke it now Dave.
looks like a 54.5 doesn't need to be de-stroked with a os 85mx piston.
Plus conversely a 53mm Kt100 and a bit piston can be used with a MB100 49.5mm crank.
52.5 and a bit KT100 piston can be used with the others that have a 50.6mm stroke.

None of that matters as Buckets is a self regulating class.

I would ignore the crashing part, the precedent has been set now.

Don't see any rule disallowing rocket launchers or rotary cannons either...
