There isnt a viable system for the T's around yet anyway. If you want a frugal high economy car a 1700kg four door sedan with a 4ltr turbo charged motor probably isnt the best place to start...

xr6boi Member 14 Member For: 20y 4m 23d Location: Albury, New South Wales Posted 01/05/06 02:53 PM Posted 01/05/06 02:53 PM yeah cause I mean everybody always says LPG runs out faster then petrol so I dunno...I would rather pay the extra for power...then again if the price keeps on rising I dunno, what u reckon?

I thought LPG had a lower calorific value (hence why you need 4 times as much of it) but a higher octane rating...Thus dedicated LPG systems can run a much higher compression ratio... ??Please explain??

To achieve the same amount of "energy" from LPG you have to use approximately 40% more by volume compared to petrol. There is no reason at all why you can't achieve the same power from LPG as you do from petrol, turbo motor or not. You just have to have the correct compression, valve timing, and ignition timing to allow for the different burn charactistics of LPG.
ZAP No boost, no bottle, just my foot on the throttle!

The problem comes with the delivery of LPG in the T when it is under boost. LPG for some reason is not being developed enough for performance applications.Pity really as Oz could be self sufficuent, as most of the worlds LPG comes from here.

Posted 02/05/06 06:37 AM Posted 02/05/06 06:37 AM 380kms DTE reads. full tank 95RON ULP and I have a K&N filter.is this super bad?2nd CAI about to go in. hopefully will see better kms. is this average for you guys?←380!!! Your doing well.I filled my car up this morning, now I do drive it like it was designed.My DTE was showing 279kms and it cost me 90.00 dollars to fill the *beep*!
