Agreed. Certainly not a way to control costs.

Doesn't Jos Goodyears Raptor compete in the under 2litre? and i would say that is far far from uncompetitive against the bigger engined cars so being in the over 2litre would make no difference surely

Or is that not turbo or supercharged?

Under Section J of the current Blue Book

"Common Regulations for Competitors: Vehicles

Engines
5.4.1. If forced induction is used, the coefficient will be 1.7:1. unless stated otherwise in Specific Technical Regulations or SRs."

It seems that all other forms of UK Motorsport use 1.7 as a multiplier, so this appears to be a case of bringing our corner of the sport in line. If you were at Gurston on Sunday you wouldn't think that Dave Uren was giving much away to the "big bangers".

Was a road car engine not the base for the 1980s bmw f1 power plant. 1500cc and power outputs over 1000 hp. That's the issue applying factors. The only limiting factor is money and development time with forced induction. To be fair they need to apply air intake restrictor size.

That was in the days when F1 was either 3 litres normally aspirated or 1.5 litres forced induction, so 2:1 equivalence factor

Radical has a spectacular aura about Radical has a spectacular aura about
The change is overdue to reconcile with other disciplines such as rallying and the developments of turbo/supercharging efficiency.

The Car v Bike engine is a separate debate.

Class divisions are set be the individual clubs and championships and already vary from place to place, if required they can adjust.

Can't really start comparing 80's F1 engines to a Renault 5 Turbos
