Diesel turbo engine capacity equivalence

[windy]

Anyone recall what the engine equivalence for a diesel engine is?

I know the turbo rule is 1.4 multiplied by engine cc. What is the reduction for a diesel? 0.7?

So to get to the point what would a 1.9 turbo diesel engine's capacity be once the engine equivalence rules are applied?

Are the rules applied across the board at all MSA sanctioned events or is it only for those organising clubs that choose to put it in their supplementary regulations?

Thanks in advance

Questions like this are springing up all over the place!

If the interest in the diesel engined alternative becomes anything more than a few people running their shopping trolleys there may be the need for some new classes!

The ACSMC run to "Cars using forced induction will be classified as having an engine capacity increase of 40%, those using diesel fuel a reduction of 50% (e.g. a 2000cc turbo diesel will be considered to be the equivalent to a 1400cc normally aspirated petrol engine)."

I've never seen anything different.

In the ASWMC championships, "All cars with engines running on diesel fuel will be subject to a 30% capacity reduction. e.g. 2000cc diesel engines equate to 1400cc and will be eligible for class A1" (Note that only petrol turbo engines are subject to the +40% capacity rule)

Its only a matter of time before someone starts competing in something like a Seat Leon Diesel FR130 chipped by Revo or similar to 190 BHP / 290 ft-Lb against the petrol 1400's.

A Leon tdi came second in class at the Pegasus sprint last year (at Combe).. I agree that it's only time that they start to demolish the petrol 1400cc cars. Although performance diesels are still rather pricey. MG ZS being perhaps the cheapest option??

Certainly the newer common rail Diesels are the ones to go for; the older diesel engines being far too heavy.

I seem to recall a chap in Scotland fitting a diesel engine into a Locaterfield a few years back and doing quite well with it!

A 130PS diesel Ibiza must be reasonable value these days..

A diesel MG ZS was used last year in the MGCC series, but got written off at Wiscombe I believe.

What class would one of those old 1l diesel Daihatsu Charades fit into?
That could be an interesting one. Might be a bit heavy for the back of an open wheeler.

Slightly outclassed by motor bike engines I would have thought...
