Thanks.
It originally came on my radar back in 2015 when I wanted t use E85 in racing, but they wouldn't allow it despite being a 'pump fuel' lol.
I'll be using the injector piggy back method, the kit is no longer hundreds but £34
Yes, can be difficult to start in cold days, the chap I know who's ran it for years simply puts in a tenner of regular then brims the tank with E85.
Lots of advantages to E85, such as winding up the boost, cooler running, less det/knock etc.
I had a factory lpg/petrol dual fuel car years ago and it was dog slow, even slower and really thirsty on lpg.
whereas e85 set up right is more efficient, more power and also allows higher boost, so whilst it uses 30% more fuel I think the reality will be 25% because one will drive using less throttle to achieve the same speed, whereas with LPG you have to use more throttle.
At .70 per ltr as apposed to 1.60euro for petrol, I reckon the equivalent cost will be 87-90 per litre (25-30% extra)
So a rough estimate, I think the running cost in fuel would be similar to a car that does 42-45mpg, but also at 200bhp with good torque which should be just enough power to make it fun.
Combined with zero road tax and hopefully a car which won't loose value, perhaps even gain a little value and you see why I don't mind investing a little to make it good, because its a car for long term.
