MPH vs MPG

[turbotoaster]

according to the latest info i could find, they pay about £1.02 per litre currently, so cheaper than us.

and why would a rotary that produces decent MPG when your in vacuum suddenly make it perform worse.

if your prepared to map it properly theres no reason why you can have the traditional rotary performance with the fuel economy associated with its piston equivalent.

With fuel only going up, do we really want to have our rotarys priced off the road.

alot of people need to use them as daily drivers to save against 2 lots of insurance/mot/tax

There is certain threshold between deteriorating of BSFC as load decreases and increased power from higher speed. Basically, engine should have variable displacement and compression ratio and work unthrottled - always use only so much power for given speed with optimal BSFC. Of course, traditional wankel engine can´t do this.

Cruising economy deteriorates with any porting, but tuning can make huge difference.

As you said your engine is standard I would find the point at which your engine is not boosting off ofthe turbos, note the mph and stay at that.

If the the turbos are in sequential set up still then search for what rpm the first turbo kicks in and stay below that point.
No boost means no extra fuel.

that\'ll be 1800rpm then
