If you're worried about loosing performance then why run it on Gas? You must be able to grab an old diesel for under a grand.... That'd save a few pennys too

Lengthen the tailpipe from the back box. longer tail outlet pipe=quieter exhaust tone according to my mate that desgns Jag exhaust sytsems. A couple mor einches should make an appreciable difference

LPG runs the same performance as petrol. It becomes dual fuel anyway which means you can select pertol or LPG.

Yeah I only have the 1 silencer at the moment with a 5" tail pipe. I might do something with that as it's a bit loud for everyday use.

The 95 RON stuff? I've seen something about LPG with an octane rating of 110! I assume that's not at the pump though and it could be as low as 90!

At the end of the day, if I can do normal driving for 32p per litre (that's the current price here) and switch to Optimax if I want to go on the track, etc. then it's perfect. I don't need top performance to cruise along the B roads and sit in traffic!

Yes, I heard gas is 110RON as well.

to my knowledge its only a slight difference in power and you will cover the cost of the conversion as lpg is cheaper so the more milage you do the cost of the conversion is covered

I was only thinking that the lower the RON the more likely Detonation or pre-ignition is, you may need to "de-tune" it a bit thus making it less fun when you do want to go for a burn. Taking a small step back can feel like a country mile when you're really used to something.

Seriously though, hat's off to you for doing it, you obviously really enjoy the car and want to find a way to use it all the time. It's not a route I'd consider but it doesn't mean I don't respect what you're doing. I didn't mean to come across like I was having a dig.
