Engine size

[S2T]

Just browsing through various regulations. Why does the Westfield Speed Series use a cut off of 1800cc for say roadgoing whereas the various other Speed Championships use 1700cc. Just struck me as being a bit odd but I am sure someone will enlighten me as to the reason

[XTR2Turbo]

I understand it was requested by the factory as 1800 Zetec Westfield was a popular car.

[Terry Everall]

originally the 1700cc crossflow was popular but then when the factory started to make and sell kits for the Zetec 1800cc engine it was thought that it probably had the same power as a tuned crossflow and so our limit was raised to 1800cc. I personally think we would be better dropping it to 1700cc like other clubs so our classes are the same in capacity

It came from competitors rather than the factory. Was a much debated item.

As a former K series owner (Elise), I can vouch for this  .

If you were setting it today without any prior constraints I guess it would be 1600 and 2000

I doubt it! Look at the engine capacities for classes as events. Nat A is upto 1400 and 1401 - 2000 and nat B is upto 1700 and over 1700

[XTR2Turbo]

I said without constraint not based on existing classes

Is there a 1.7 litre engine made today?

I thought some of the road going Caterhams ran ZZR tyres which were fitted as OE
