I'm running duel fuel, yes i know dont bag me I want to score more power out of it by adjusting the cam to about 20 BTDC. Is this ok do to running LPG? I have cold air induction, K&N Filter, Extractors and 2.5 zorst. LPG is said to have a higer octane, so in theory i should be able to advance the cam a fair bit right? Thanks Some original photos have not been recovered yet.

Dual fuel here too .. and after asking this question for ages both here and aus.cars and not getting much in the way of an answer, I decided to try it .. runs beautifully .. running about 22bdtc at the moment (dizzy advance only, not cam belt advanced) and its definitly notibly different .. i like it Runs nice on petrol too, tho i think thats more the Fueltronics ECU taking over there Some original photos have not been recovered yet.

Have you had ur car on the dyno? if so how much rwkw did it pull? With 2.5zorst and Extractors mine got 87rwkw, since then i have added K&N filter & Cold Air Induction. With these mods and timing advanced i was hoping for 100rwkw.

nah .. never dyno'd it .. almost did .. had the car in for service on the LPG tank (buggered multi-valve) and noticed the place had a dyno .. enquired about rates .. seemed decent .. got scared off the idea when he mentioned the waver you have to sign and how its likly to screw the tranny .. untill i can afford to repair/replace stuff if it does break, im not gonna do it only mods to mine are cold air intake, air filter, advanced timing and fueltronics ECU .. when iv got some cash spare, extractors will be next .. would be interested to dyno it on both fuels and see the differences .. which fuel was yours done on?

on ULP i got 87rwkw. On LPG 82rwkw. Sign a waver? **** THAT! a dyno shoulndt screw the transmission, ask around, find one that's good, i'm in the sticks so mine will be of no use to you. I'm hoping with advanced cam i'll get out of petrol 100rwkw, but i think i'm hoping a little too much :P Hopefully i'll be getting a VLTC very soon so my N/A will then become my GF's, so i wont care too much about the power then.... well for the NA anyways :twisted: Some original photos have not been recovered yet.

I'd be interested to see what mine is actually putting out with such relatively small/cheap mods .. WIsh i could have done a before and after with the fueltronics ECU .. i'd almost be tempted to borrow one and do a comparison sometime .. I dunno .. the guy just said for cars older then 10 years they require everyone to sign a waver, as things can go bad .. kinda scared me off a lil bit Some original photos have not been recovered yet.
