I have a Terri Turbo with good 2YO vapour LPG injection, and that introduces petrol at high load for sure. The Liquid LPG is system very high pressure, higher than petrol (and very cold) and so doesn't need petrol added in. Link to comment Share on other sites More sharing options...
Bizkets is Drunk? Too heavy needs boost Member 5,929 Member For: 11y 3m 18d Gender: Male Location: Adelaide Posted 04/08/14 06:47 AM Share Posted 04/08/14 06:47 AM - I now have 275rwkw, and 620nm torque. Proven, on the dyno. That's power to weight of 220w/kg. Not too many cars in that group. That power equates to roughly 390kw at the flywheel. That's roughly 525HP in the old. Its a lot. Too much for my crappy Stiletto Blue Streak tyresso your saying you think you are making 390kw at the fly and 275rwkw. so a loss of 115kw through the drive line doesn't sound right. the not to many cars in that group comment. love it. Because there aren't to many cars on this forum under 300rwkw so I guess not to many in that group. Link to comment Share on other sites More sharing options...

There's an outside chance that you might know a bit more about it than me ;-) If you have a better method for determining approx engine kw from known rwkw, please let me know. 275rwkw is more than enough for a crap driver like me.

tburke Member 15 Member For: 10y 4m 6d Gender: Male Posted 06/08/14 12:55 AM Share Posted 06/08/14 12:55 AM To answer the question. Yes. For me, doing lots of kms/year it'll be paid for in under 12 months, and I got a performance tune thrown in. TXR05 Link to comment Share on other sites More sharing options...
barnz Member 3,047 Member For: 11y 3d Gender: Male Location: Brisbane Posted 07/11/14 02:40 AM Share Posted 07/11/14 02:40 AM (edited) Well after reading this thread and owning a 5l au2 on lpg for a few weeks im getting pretty serious about gas on the g6et.Could anybody recommend someone in brisbane to do a dedicated liquid injection setup on an fg turbo? Is it even possible to do dedicated yet? Edited 07/11/14 02:41 AM by barnz Link to comment Share on other sites More sharing options...

barnz Member 3,047 Member For: 11y 3d Gender: Male Location: Brisbane Posted 07/11/14 08:57 AM Share Posted 07/11/14 08:57 AM (edited) Ah okay makes sense. Well I know you have installed a fair few setups on these cars now Ratter, is there any particular setup you would use and recommend? Do you know of any reputable installers in brisbane? I was thinking of seeing if FPT could do it. Or do I need to drive to Frankston..my AU came from Frankston...Also do I need to do petrol injectors as well if I want to make around the 300rwkw mark.
