pwede kaya upgrade from carb type to sgi???

afaik, yung injectors ng lpg kit ng sgi is adapted to the injectors din ng engine talaga ata. so i think hindi pwede. that's with the macro's sgi kit anyways.

is there anyone with a macro kit here? share experience..?

I just wanted to post... I drove my Corolla to Baguio and back over the weekend. I had both my LPG and gasoline fuel tanks filled. When I got back to Manila, my odometer was reading over 650 kilometers. I did over 400km on LPG (started with 83% tank capacity) and the rest on gasoline (gasoline gauge was reading a touch over half remaining). The LPG tank wasn't dry-empty but the meter was reading zero for over 15 minutes before I switched over to gasoline.

While in Baguio, I was running on gasoline because the thinner air resulted in one very under powered Corolla which was able to so slowly around but it was inefficient on the fuel used.

The portion of the trip to baguio was mainly done in rain but I was still able to maintain a speed of between 100 to 125 kph along the expressway. If I maintained a lower speed (like 90kph) all the way, I might have achieved better fuel millage but I was trying to cut the travel time. Manila to Baguio in five hours. Baguio to Manila in four hours.

naexperience ko to when checking the lpg gauges na nakalagay sa dash ng naiadss kit. meron kami units ng taxi na hindi sya accurate reading. meron din nagpagawa kasi nagstall yung taxi nya thinking may laman pa kasi sa gauge meron pa tapos wala na din pala. so i guess d kami alone on this. i guess even private cars experience this as well?

it's no big deal naman though. check na lang gauge sa likod i guess.

share ko lang din. sabi samin ng macro they did consumption tests and that on their 1 full tank, it reached 550+kms. sa taxi, normal samin making more than 450+kms tapos d pa fully-emptied yung tank.

share ulet: given na 1full tank would be something like 1.4k then 23petot/liter... tapos 450kms flat kunwari.. that's something like 7.39kms/liter of lpg. para lang dun sa curious regarding consumption.

mga sir tanong ko lang po kung kamusta ang expedition pag pina convert po sa LPG. ano po ang LPG tsaka gas consumption?

[ssalonga]

mga sir, may gumagamit ba sa inyo dito ng made in turkey lpg kits? mas mura kasi by 10k compared to tartarini and marini..... i believe i need to do a convertion asap as i am now spending 15k/month for my gasoline

the Turkish "otogas" industry is quite advanced. The Turks have partnered with UK and Dutch manufacturers to produce some of the most advanced equipment for road going LPG conversions.

I really could have done more with my tank of LPG. First, I started with 83% tank capacity (previous out of town trips had the tank gauge reading over 90%). Next, I have traveling faster on the NLEX than it was good for economy. I was around 125kph, economy driving would have pegged me at 90kph. Then I was accelerating hard to overtake some of the slower vehicles on the way on the rest of the way to and from Baguio. And then considering the climb up via Marcos Highway.

I just filled my tank yesterday (warning beeps for the last 20km) and it only filled to 44L of LPG before the pump cut off.

Consumption should roughly be the same as gasoline, especially if you would get the SGI LPG kit for an Expedition. Personally, I haven't seen an XP refilling with LPG but I have seen a Ford F150 with a LPG kit installed in one of the past car shows (LPG tank in the flatbed hidden in a big "toolbox").

looking to upgrade your LPG performance?

[chuaed]

looking to upgrade your LPG performance?

yes... pwede kaya?

[ghosthunter]

yes... pwede kaya?

http://www.difflock.com/lpg/systems.shtml

from the looks, I think you will need to replace the whole system.

[chuaed]

thats sucks...

thank you sir... this is the brand i am referring to. it is being installed by a company located at pinagbuhatan, pasig. they are the ones manufacturing the tanks also (to include the petron gasul lpg tanks). they also carry another brand, italian made, and a bit more expensive. may poster po dito with the voltran kit? inputs pls

OT: this company at pasig is the most professional lpg provider i dealt with (pero di pa po ako nagpapakabit as i am still undecided on what brand to install). i highly recommend them

How can you recommend them when you haven't dealt with them yet?

why do you say they are the most professional...eh you havent tried them yet?

hector angel,

you asked if carbed cars could be installed with SGI. The answer is yes but the technology may have to be assembled from various suppliers and will require a "stand-alone" ECU with programmable firmware.

Also the resulting installation will only approximate (in some cases) exceed the original petrol performance if the engine itself is modified to work as dedicated system.

I am currently assembling such a system and will begin installing on my 1985 MB 200 W123 sedan probably by next month.

Actually if you already have a venturi kit installed -- the boot end (tank multivalve and vapor box) remains the same and usable.

The "front-end" will need a new regulator, fuel rail, and the vapor injectors tapped directly into the manifold. Its probably wise to get the front end as a set. Prins of the Netherlands has the best injectors which are OEM from Keihin of Japan, makers of injectors to major manufacturers.

PS. May I have the name and address of the Pinagbuhatan installer? I live in cainta and would like to visit with them soon!

how can i get in touch with them?

BTW, if you are looking for more options for local converters, you might check out an importer of kits from New Delhi, India which are just as good as korean and italian kits:

mga sirs, ano na po update dito? interesado pa naman akong i-LPG ang ride ko. its a carburated 2.6L 2dr pajero. thanks.

what kind of update do you want?... we have been using LPG in our vehicles and have encountered no major problems.

maybe you can just summarize the effects of converting to LPH...

Reduction in fuel economy (if for example you get 6/ltr on gas...how much reduction will you get on LPG

Reduction in HP (i heard that HP of car will deteriorate when switching to LPG)

other effects....

thanks!

fuel economy:
switching to LPG carb system will result in a general decrease in fuel economy. So if you are getting 7 or 8 km/L in gasoline, expect 5 to 10% decrease. If you choose the more expensive SGI LPG system, expect your fuel economy to be the same as gasoline.

horsepower:
horsepower output for a typical 1.6L efi engine is claimed to decrease by 5hp. My view on this is that the "mixer" is the culprit since the venturi system constricts the flow of air going to engine. At higher RPM, I can see higher vacuum pressures in my intake manifold than before the LPG system was installed, especially at WOT. If you choose the SGI LPG system, your horsepower might increase by 5%.

system leaks:
as long as you keep the gauge cover installed, any typical leaks would be vented to the outside and disperse to the environment. The "smell" will not enter your car's cabin. If you have a leak, simply take it to your installer and they will fix it. In my one year of driving with a LPG system, only one leak occurred and was fixed by tightening a couple bolts.

long term maintenance:
You will need to clean your air filter more often for the LPG carb kits. SGI kits would have no change. Contrary to what the LPG people say, oil and sparkplug change schedules should be maintained as with as if you were running on gasoline. Also remember to drain the LPG evaporator once every six to twelve months (depending on your mileage). This takes less than five minutes at your LPG installer.

thanks!!! am thinking about having my camry converted...anyone here have experience on this? also, how much would it cost to have it converted....

thanks again
