M35 Stagea Dimensions For Lpg

[iamhe77]

i was expecting the gains to be about 10-15%.. the ECU will advance the timing automatically within reason.. (same way it retards it when you put shit fuel in it). all the LPG will do is ensure that the intake temps are always icy cold and that there is plenty of octane available.. the ECU should do the rest.. my mate even ran on pure propane for awhile which has an octane rating of 110 and is a couple of cents cheaper than LPG.

though yes your right to take advantage you would need aftermarket engine management.. i am hoping one day nistune work out the VQ25DET as i much prefer piggyback to completely new ECUs.

Supagas on Dandenong have "premium LPG" on pump that is guaranteed 110RON

i bet its propane! or just more propane than butane

[Sage222]

went down and had a chat to the guy today. he reckons we can fit a 45L in the spare wheel.. bit small for my liking.. though he is going to see if we can get a 50.. reckons between $4500-$5000 installed. plus you get $1500 from the government.. sounding promising..

So why don't people use LPG for kw gains as well??

Its too hard to evaporate enough gas out of the tank with a vapour system, liquid just costs too much I think.

[Chris Rogers]

well I will say one thing. it certainly did not lose power when on gas. I have driven this car and its not noticeable just cheaper to run. unsure what it will do distance wise with the cruise on though.

[Sage222]

i would never go a vapor system.. just too much f*king around with tuning.. liquid is far more simple.. i have heard issues with AFM and o2 sensors with vapor though no issues with liquid.. you pay the premium though especially with a 10-20% increase in power its worth it imo. (tho saying that iam sure there are a lot of people who have never had an issue with vapor too).

[Sage222]

ok gents.. im booked in tuesday week.. only took filling that 80L tank once with 98 premium to convince me! $103!!

My car did 13L per 100.. with the power gain i will be wrapped. ended up being $4600 installed and get back $1500 from the government

thats $19.50 for every 100kms.

on gas with 5% more consumption (call it 15L per 100)

$9 per 100.

Will let you know how it goes.

Excellent!

Is that with 1 or 2 pumps in the tank?

I asked for something that could handle around 500-600hp in case I decide to power it up that high in the future and was told that two pumps in the tank were required to move enough LPG for those power levels (only an extra $150-200 if I recall correctly).

Did he give you a max volume per min that your setup can deliver?

Definitely look forward to seeing the quality of install as I hadn't spoken to them about a system.

[ironpaw]

Let us know how it goes...I'm definately interested if the results are good.

[Sage222]

will do. I asked him about what sort of power can it flow. he reckons essentially all the injectors are the same.. (has installed this system on a 500HP V8) they just use different nozzle's basing it on the injector its currently running. so as i said early.. they take out the factory injector and then put on a nozzle on the lpg injector than can flow the same amount.. so the factory ECU controls the LPG injector thats what makes this setup so sweet.

So if you wanted more grunt down the line.. i guess you could just bring them a different injector and they could match the nozzle to that.. though if you didnt actually install that petrol injector you would want to be EXTREMELY careful if you then run the car on petrol.. with completely different flows and less octane your asking for trouble

dont know its one or two pumps.. i imagine 1.. i told him that they car should make approx 230kw and 460nm and he said no problem.

He reckons he can get a 50L into the spare wheel well though if he cant might have to be a 45L. Either way should be good for a bit over 300Kms per tank.

Thats a plus, im getting just over 250km on 98 - car isnt tuned yet

Interesting to see how it goes!

Jeeeeez...how long you been doing this? Think you would've saved the $650 needed to fit and tune emanage by now!

[Sunkist]

Dude the eManage is installed.. I was about to get the trans done but the turbo died again lol.

FYI My M35 axis autech 2002 takes 51 usable litres which is a gross tank size of around 60 something

So you've done the conversion?

EDIT: so Chris Rogers was referring to your M35 when he mentioned it didn't lose any power?

DONE!! M35 now on liquid injection! Tamme at Seaview Auto Gas conversions in seaford was great!

So now what everyone is curious about how do i like it..

well...

its f*kn awesome! i swear the car feels smoother on this and pulls harder than it used too! id say 10% feels about right from my asscheck dyno.. if the volvo made %14 more grunt then i guess it should be about right..

to be perfectly honest if no one told me i wouldnt have picked it was on gas at all.. it just feels exactly like petrol except that even though it 21c on the drive home it felt like i was driving it on crispy cold morning at 5am..

idle is perfect and so is everything else.. start the car cold on petrol then after about 30 seconds you hear a beep and your on gas.. cant even feel the changeover.. they did a sweet install and spent a little bit longer to ensure the plastic covers all went back on.. they even managed to get the gas filler just under the petrol one so all nice an tidy.

and the best part of it all?

$30 for 50Litres! (61c per litre)

vs

$74 for 50 litres of 98 octane (1.48 per litre).

also asked him about making the injectors flow more if you put on aftermarket ecu he said not a problem.. prob an hour or so to change the nozzles on the gas injectors.

couldnt be happier.

f**king awesome. I'm down for this after emanage is installed...

U should get it dynoed

So far win/win ! Please let us know what range you are getting on the gas after you've been thru a few tanks. That will give the true story of the economy gains. It's great that it's running so well.

[iamhe77]

Awesome mate, just awesome.

Glad it all turned out well.

$30 for 60L... definitely on my must do list.

Any chance of an engine bay pic without the engine cover to see what is going on in there?
