LPG and Turbo

[Skotty]

I've been looking into running a turbo setup on my EF, and my car is on gas... can anyone shread some light onto running turbo EF/EL's with the GRA setup? I've seen it been done, I've been told by the mob doing my install its not realy worth it tho?

Does anyone have some links on where I can research some more..

thanks!

[pHaT`eL]

check out either EFFalcon's or Sundeep's threads in the workshop build to see what can be done with Gas turbos.

[Skotty]

Last I say, EFFalcons EF only mate 178rwkw? I'm aiming for the 250ish rwkw...

I was told I could run a boost controller, on LPG run it on low boost its all save, then on petrol I *should* be able to wind it up some?

[EFFalcon]

my EF only made 179rwkw on 6psi, on a motor with screwed rings.
ask anyone who followed me about the oil smoke

you can run high boost on LPG so i don't see the issue.

[LTDHO]

EFFalcon made power with a dieing motor that would not die.

It has the benefit of respectable power and cheap to run.

[EFFalcon]

haha... they stopped running it on the dyno coz it was fuming up too much

[YBYAVL]

i had the GRA setup on my 250
wen it was in the XE it made 220kw@rw on 7psi
couldnt boost it coz it was starvin for gas...
i ended up bolting it all in a TE cortina an set it up with a 2nd gas line an converter but never got around to finishing it
would have gone good me thinks =/

Ill be running my set up with GRA, twin B2s and twin tanks on a wagon. the only proof ive ever needed that GRA turbo 6 is the only way to go is the XE running nines owned by a guy named jason and gas-747 vl running low tens.

to be truthful i cannot understand why more people arent going this way, you dont have to worry about ecu, injectors, pumps, tuning as frequent and carbon build up.

and the best part about it you can buy 100% propane from supagas which they claim has an octane rating of 113.

My wagon will be run in on vpower racing with 260cc injectors and a walbro stndrd ecu and then booked into swift for a gas install which will be partially funded by the government.

[EFFalcon]

sounds like a good plan
swift did my initial GRA install

lets not encourage people to go to LPG, will make prices go up

[YBYAVL]

jason used to live at the end of my street untill the shit hit the fan....

fuk his silver XE was tuff....full 100% street trim on ghia rims.... 11.071
the day he took me for a ride in that was wen i turnd to LPG...
usd to sit on the front nature strip lol,
onli thing that gave it away was the slix an rubber up the guards...
he had a cream 1 aswell, that thing was a mint sleeper...

that an Adicted performance apprentice's VL goes 10.80


RESPECT GAS!!!

[Skotty]

So, my understanding so far is, that I could run a GRA setup still, and have my car on dual fuel - once turbo...?

Once I get the stinger ems tuned on petrol, will it still be able to run or will the petrol tune be too good?

Would I be best looking at a cappa eliminator switch?

[Yianni]

Gra is only for straight gas set ups, your original throttle body is replaced with the gra unit to suit your power. No duel fuel, plus I don't think it would be viable to have a performane motor set up correctly on the 2 fuels

[Yianni]

forgot to mention you can use other gas set ups to acheive dual fuel, but very hard to both to perform 100%. Set it up to run LPG from the start and you won't regret it. 60 c a litre and higher octane cleaner burning

[Dansedgli]

You just need to fit a stock TPS and sort out the isc and you can run dual fuel with GRA on a efi car.

[Yianni]

I stand corrected then? I'm only going from info I received from swift. Question is if you have LPG and it set up is suited why would u want petrol?

[nothin suss]

Because LPG is hard to keep contained in a jerry can when you run out.
I will be going single fuel when my car is no longer a daily to clear some space in the engine bay, i just cant bring myself to doing it right now, my car is real reliable on LPG but there is always the risk of running out.

[Yianni]

That one negative can't way out all the positives and that's easily fixed with an $80 Racv membership if your prone to running out of fuel.

[Dansedgli]

There isnt that many positives. If you have a good aftermarket ECU and a decent fuel setup there is no reason you cant run both.

[EFFalcon]

exactly, theres no reason u can't run both, but it does seem a bit of a waste of money.
why spend big on an LPG system and a petrol system.
concentrate on one and spend the money elsewhere.

if you're concerned about running out, keep the fuel system in the car but leave it stock.
then you can atleast use it to limp to a servo or what ever.
just don't let the petrol system run dry as you'll kill the pump.

my car was dual fuel for the first 6 months of turbo!

[Yianni]

I understand where your coming from but i cant understand the reasoning behind it apart from thrwoing money away? Again im refering to an all out performance set up, not a cruiser with low boost.

[Dansedgli]

For a decent turbo setup you need an aftermarket ECU anyway. Injectors and a fuel pump are like $600. Thats not that much cash so I would do it but thats just me.

I wouldnt want to do an interstate run on LPG only car again.

Oh and if you wanted an all out performance setup wouldnt you choose a fuel that more than 3 people know how to tune?

What do you mean 3 people? you refering to LPG? If you are, you have lost me as there are many people who can tune LPG and its not rocket science.

Each to their own, i personally think LPG is the way to go and love the fact its less than half price of ulp. All this is theory at the moment so i may have a different opinion once my daily driver turbod wag is complete. Time will tell.

[Dansedgli]

Im just saying you can count all the 9 and 10 second LPG cars on 1 hand.

The majority of which were built by Jason Ghiller and last I heard it was kinda hard to book your car in with him.

I agree thats its a good idea, just not ideal for available tuners with proven results and shit house if you want to go on a long trip away from a petrol station that sells LPG. I would love to put the maverick on straight gas so I could turbo it but some of the weekend trips we do cover a lot of K's and LPG only wont make the distance.

[EFFalcon]

dan's right on the tuning issue.
its hard to get a decent tuner... yes LPG generally is easy to Tune, but GRA isnt ya average LPG setup and many people don't know how to do it effectively.
some LPG places still refuse the fact that LPG + Turbo actually works.

[Yianni]

thanks for the Info I'll be asking swift and rapid alot more questions before I book in.

[YBYAVL]

well apart from the price, the onli reason im on straight gas is to stik a big dik up EPA's ass...
no emissions laws =)
where as a 308 with a holley in a VK is illegal....
ino this dusnt concern EFI but u still have all the ugly emmisions control shit all over the engine bay..
and with dual fuel u still have tor un all ur emissions gear, as far as EPA r converd if u have any part of a fuel system in ur car
u gota pass emissions standards...
so ye...straight gas is the way to go
and to correct nothin_sus
u can store LPG in a lil BBQ bottle with a fitting to transfer it into the car
ive ran outa gas b4 an it sux lol

*flips the bird to EPA*

[EFFalcon]

the EPA still applies to post 87 cars

so straight LPG on an Eseries still needs emmisions testng.
