Just thought i would put up my thoughts on my new take on Gas Research LPG system.
As much as i would love to go Liquid or Vapour LPG injection it seems at the moment that i can't justify spending 5-6g+ on a setup, maybe in 3years + when i can get my next LPG grant and hopefully the prices come down a little

But for now i am keen to hear peoples thought and sugestions on a setup simliar to this for my in the build 355 LH. Has to be under bonnet no scoops etc.
Really don't like the look of the standard GRA twin T/B convertor setup, but this i do like the look of






Yes i think its a Ford, and know i wont have twin turbo's YET.
Would prob joint the two pipes at the front and run it under the rad hose and into a pod or airbox where the charcoal canister goes or into the guard. Convertors i will try to hide under the guard if the hose isn't deemed to long for this.
Planning to go single turbo later on so this setup should be easily adapted to that at a later stage.
Do you guys think that this "active" style hat will flow ok?? I was thinking of using one of the active hats buy have heard that they don't flow that great in NA.


Also peoples thought on tank location: In the LPG standard under the parcel shelf setup i am told this is good because it keeps the weight over the rear axel, better handleing???????? or does the higher centre of gravity undo any advantages????
Like Knoath, large tank in tub cut into the boot floor, std petrol tank position, were the car was desiged to take the weight??????
Don't care about boot volume loss just wana know whats going to handle better!
Not looking into the manifold tanks coz they have a smaller capacity and are harder to plumb a true twin oulet, twin line setup into which i need for my power levels


These look awsome but are not to proven in higher HP NA and Forced induction setups that i know of yet, but will still look into them as i would prefer the stock look. Anyone know of a fitter installer that would fit one of these in Melbourne???
Or any reports on them????

I'm working at APA at the moment and have looked into the best tanks to fit into a Torana. The best tanks we have are the manifold tanks. Look a bit like 3 scuba bottles. They hold 59 litres of gas and should go where the standard tank goes. Not entirely sure on the clearance with the spare wheel well but apart from that it would work quite well. Also have a look at the factory Ford LPG tanks. The Wagon and Ute tanks would be the ones to look at and carry about 90 litres of gas. However their size may be a problem.
Although one thing I have looked at is, the Ford ute tanks are two tanks bolted together and linked with external pipes. There are 2 different sizes of the 2 tanks one about 35 litres and the other about 55 litres. So to gain clearance you may be able to use 2 small tanks bolted together with the necessary piping to link the two tanks. The tanks are 285mm in diameter so I'm not sure with clearance underneath however my thinking was it was about the depth of a droptank. This set up will get you a greater volume of gas to the about manifold tank but clearance may be a problem.

Oh and you do want the tank as low as possible so anywhere near the standard tank location will be the best for handling.

I guess alot of torana's have drop tanks and still seem to handle ok so extra weight in the std pertol tank location would prob be ok.
Anyone notice a significant difference in there cars handling with a full->empty drop tank? better, worse?????

lhmusl do u have any more gas pics??or any of ur old set up???

what bout twin 425 impco carbs on a tunnel ram.got pica of this on a 308 and is pretty decent set up!

[Guns n roses]

twin 425s on a 308 with 2 converters.

[LhMusL]

Yeah i would go twin impco 425's IF there was a low rise twin carb manifold for VN heads!! Has to be under bonnet so no tunnel rams for me. Have seen twin 425's on a similar GRA setup but that looks the same as a GRA setup and thats not to my tastes.
Would really like to go the technocarb path so it can look stock, just researching it more. But the twin GRA front mount setup would look killer when i get a turbo though
Old setup was out the bonnet and a bit of a head F$&k so not doing that again, Here she is

[Peter UC]

I've been doing a bit more research on the tanks and the manifold tank I was talking about doesn't fit under the car as it is too long and the two Ford tanks would be too low. So unfortunately without more research and expense it seems the only real alternative is the tank in the boot, which would be a A86 which holds 68 litres or a F84 which holds 60 litres.

Smithy's Car Repairs in Bayswater said he fitted a manifold tank in the std torana tank position years ago, although i don't know what other mods were involded. Didn't someone who got there system fitted at Rapid Flow get like a 90ltr tank under the parcel shelf in there LH??????????

[Guns n roses]

im not sure wat size my tank is but its under the parcel shelf and i dont need speaker spacers for 6 x 9s..

hey luke do you know how much those techno carbs are worth??

[LhMusL]

Think i got quoted about 1500ish for a whole front end setup, then you just get a tank and lines + fitting and tuning, so prob similar to a GRA setup or a bit cheaper.
TorqueGas in QLD is a australian distributor for them they seem helpfull but the dude was trying to say how good they are when they got 200 rwHp out of one...... i want 270+ rwHp

[Guns n roses]

wonder what the cars are worth on just there own.i got gas research and was looking to do something else cause i really rather a air cleaner or something throught the bonnet.like twin impcos or twin technocarbs on a tunnel ram

[LhMusL]

800cmf techno carb was about $950 i think.

[Guns n roses]

hmm hope the 660s are a bit cheaper!!!
