A question for Duddha.

The appendix to K that details damper types suggests that in period F ‘steel bodied, twin tube, double adjuster’ dampers are legal.

BUT, is that ‘legal’ only if proof of period fitment to a particular make and model in international competition exists?

If you read the first paragraph of that 3 page document, you will get your answer, the table is a summary, it shows the technology available back then.

FYI There will be an update coming out 08.03.2019 for the Supplement 1 and reinforcing the period specification aspect.

Thanks. I was asked by someone why they couldn’t have double adjuster dampers on their car, and thought the answer would be because there is no period proof that model used them in period....

Wonder how many are being used though? Difficult to spot if painted in FIA Black.

Wonder how many using can really make profit with all the settings. I remember the 996 Cup having too many for us.

I’m sure many get confused by having too much adjustment!

Unless a car is a complete dog, I tend to adopt the ‘just drive it’ approach......

If its a dog it will stay like this the shocks settings are not everything, fully agree with you! Look the modern stuff, everything's adjustable, low speeds, fast speeds, you need datas and a good engineer.
One thing I find interesting are the hydraulic or air small "ressorts compensateurs" allowing to adjust the ride height remotely. Good in rallye.

I'm trying to confirm valve and choke sizes for App.K Lotus Cortina. Does anyone know or can give me the number of the homologation papers. Thanks

A quick check of the 1966 Homologation papers shows a 40mm choke size for the Carb , & valve diameters of 38.86 mm inlet , 33.66 mm exhaust

We're talking about Grp1 aint we?
Want a nugget? Amendment 4 Evolution or Optional Equipment Group II, 16a # Ref 159 Connecting Rod Weight 650 kgs. (with bolts)
You need four of them… and total weight for the car is 812 kgs (amendment #1)

Robyn having a look to appendix K is worth most of time…

They would be standard diameter (not sprint BVH size then).

40mm choke size or 40 DCOE? I had assumed App.K could use 45DCOEs.

I'm trying to determine if there's a maximum (removeable) choke size.

Thanks

Although I believe the dimensions Robyn is looking for are the same, my take is that it is the earlier 1963 homologation #108 for FiA cars?

The paper I looked at was Gp 1 .
That had the carb size listed as 40 MM , so a 40 DCOE should be used in Gp 1.
If it was running as Gp 2 then carbs were " free " , so any size could be used

The removeable chokes would be sized to suit how it was running , & along with jet sizes were also " free" under Gp 1 rules .

I will have a look through some other papers to see if bigger valves were homologated for later models .
