Sjorzie Member 27 Member For: 14y 11m 1d Posted 17/02/11 06:30 AM Share Posted 17/02/11 06:30 AM Hey guys, I have a BA XR6T with a parnell lpg system, I have done the following bigger cooler Crow valve springs Walboro fp Deka 60 ngk .7mm copperI got a cutom tune done and only got 268rwkw on petrol, he thinks there is some exhaust flow issues and reccomends a dump with seperate wastegate port. Is this a logical step?the lpg guy has problems matching the lpg flow rate of the 60lb injectors, I have seen people using the bosh 36lb on lpg cars as they are a cloer match to standard? what sort of power can these make ? im guessing the 42lb are also too big?This xforce one seems better?cheers guys Link to comment Share on other sites More sharing options...

It produces more power then petrol as it's 100+ Ron... And up to 110 RON for 100% propane... My tune was on standard gas (50/50) of butane and propane... But when I put 110 in it, you could feel the difference... Link to comment Share on other sites More sharing options...

(ie 1 gram contains less energy than 1gram of good ol Pedarol)Its harder to burn (hence the 100Ron rating) so it can take more squeeze before it goes back, which also means it loves timing advice.E85 is much the same, cept it also self oxygenates...MMMMMM Oxygen Link to comment Share on other sites More sharing options...
