ersko pat

hi guys, i have a 4.2 efi gq patrol and had a set of extractors fitted to it about a month ago. the difference in mid range power and torque amazed me as i wasnt expecting a performance lift i just wanted some improved economy.
my patrol went from around 20 -22l/100 km to 14.25l/100km an amazing improvement. the exhaust gas sensor also was found to be faulty when the extractors were fitted. i am really happy with the results on an otherwise standard vehicle ( including the rest of the exhaust). i have hurricane headers on it and they cost me $375 fitted, add $95 for the sensor and it will have paid for itself by christmas!! thoroughly recomended!!!!!

LMAO Bill n Di means, Laugh My Arse Off, Truckster having a dig.
Before i had it done i was getting around 700-750k out of 150 litre tank. recently i am getting 840 out of 120 litres. I'm sure the exhaust gas sensor had something to do with it as well because it measures the unburned fuel in the exhaust and adjusts the air/fuel ratio accordingly as im sure Truckster would know being the expert he is!!!!! Do you think if i send him a calculator he would be able to work the figures out ...... maybe i would need to teach him how to press the buttons.

Ersko..

Yours would go down in history as the only Patrol to put extractors on a car and get 8k's a ltr better, get a trillion more KW, and actually believe it. 99/100 GQ owners that put extractors on get 0 difference, but all defend their $ investment, otherwise you would look stupid stating that you spent a grand and got nothing from it wouldnt it?

You should have alook at the Poll on the GQ list... yours would be about the only Petrol getting anything like those figures..

Maybe they should all buy Hurricane extractors and new gas sensors eh.

LMAO..

Truckster,
if u look further down the page there is another who is getting similar figures, and if u and looked at my previous question (dated 14th july post number 14656) u would notice that there are a couple of more guys saying the same thing, maybe some of us can drive without our foot on the floor.
I never made any claim of A TRILLION KW what i said was that i got a noticable improvement which i wasn't expecting, i was just hoping for some fuel economy.
I cetainly don't feel the need to defend my "$1000" investment to anyone on this forum as i happen to earn my own money and will spend it how ever i please, also as i have stated the extractors never cost me anywhere near that.
I also have tried to briefly explain how an exhaust gas sensor works and the effect it has on the air fuel ratio, but maybe u just don't want to hear it because its a "stupid" persons argument.
if the ecu is not getting an input from the exhaust gas sensor, or any other sensor is will default so the vehicle will continue running. 100/100 times it will put too much fuel in.
i have always said that i'm sure the new sensor has had a bit to do with the increased economy.

Heres the results of the GQ Patrol forum thread on TB42s on petrol only

15-17/100 50.00%
18-20 / 100 1 10.00%
I dream of better than that 3 30.00%

Heres the results of the GQ Patrol forum thread on TB42s on LPG
13-14 ltrs/100klm 11.11%
15-17/100 22.22%
18-20/100 22.22%
I dream of better than that 44.44%

Having personally installed extractors and zaust system, and mate who I 4b with all the time, both got ZERO result.. As have numerous others.

Thats why the mass disbelief, not only from me...

Hi Uppy,
Thanks for the support!! I paid $375 for the extractors fitted but had quotes up to $680 for extraxctors alone and $950 for a complete system so shop around. The guy I got to do mine said that they would have been $425 but he had a set in stock so I could have them cheaper.
I recently drove to batemans bay and back (around 520 kays) and the rest of the 840 kms was running around sydney, so theres a bit of both in there. My city kms are not real good as i only travel 8ks each way to work, i let it warm up for at least 5 mins b 4 driving and stop to get the paper and leave it going at the servo so its actually sitting idleing more than its doing any kays. (but dont tell truckster cause he won't believe that either lol). That was on pulp as i run it thru every 3rd tank.

"They can go anywhere the desiels go,so whats the problem"

bleepfuel economy to start with. Meaning you have to leave 1/2 your stuff behind to go same distance as a diesel so you can stack your car with jerrys.

Ask 3 blokes in our club - one is property manager Trevor Heale... who traded his 4.5 in on a 4.2 diesel, and has done more trips now since he doesnt have to carry jerrys. Not sure which trip it was, he stated he had to carry 10-15 jerrys... Trev does 1 major trip a yr, + numerous others (eg Robe, cape), and likes being remote away from stores and stuff.

Hi Truckster,Im surprise that you ,Dont know that you can order 220lts of fuel to be delivered in remote parts of the outback.If you order and pay in advance.So you dont need to carry as many jerrycans.And I do have to unload half my wagon to get over a sand dune.

"Get over this problem you have regarding petrols."
SO your saying, follow my thinking as its the only option.... dont think for yourself??

So, who would go further on 145ltrs of fuel, TD42, or a 4.8 Petrol.

Simple question - same section of road, same conditions same speed and driver.

Get over this wet dream you have regarding petrols..

That is a big improvement might have to look in to it so hurricane headers is the brand of the extractors? (sorry just never heard of them) where did you get them installed?

i had them installed at cobra exhaust, penrith nsw. yes hurricane is the brand but Lukey, Perry and i'm sure many others' make them its just that the exhaust mob i used are huricane dealers so i went with them. I'm sure the other brands would work just as well.

Eric, i don't know about other GQ's but mine is a '92 model TI first of the injected models. it certainly didn't have a style exhaust system on it, mine had a big heavy restrictive exhaust manifold.

it dosnt actually mater what it looks like , its the way the outlets are made to flow in firing order . Headers are set up so that when a cylinder fires, it asists the removal of gases in the next firing order , so yes they can be bulky . Restrictive can be a exaust system .

I have a 92 EFI GQ also, I had Genie extractors fitted many years ago, and found the low to mid range tourque increase was impressive to say the least (left the rest of the exhaust as the restrictive standard system). I didnt get a single bit of fuel econemoy improvement, but wasnt looking for it either, was chasing imprved low end tourque.. last year finally replaced the rest of the exhaust as the muffler had finally rusted out, put a 2.5 inch system all the way thru with a hi-flow muffler and resonator to reduce the noise (the system is all Genie brand).. This is where it gets semi interesting,, my power and tourque increased slightly, where i thought it should have got alot more as the exhaust was now a free flowing one to help the extractors do their job.. and the fuel econemomy actually went down by approx 1-1.5l/100km for country touring... Replaced the ignition leads with new Bosch inductive leads and got an increase in power/tourque.(had it re-dynoed while tracking bad spark issues).. old orginal crappy leads proven were old and crappy :-)
output at rear wheels according to the Genie Dyno are 99kw at 3700rpm, and 271Nm at 2000rpm.. It would be nice to know how much power is lost thru the drive system so I could get an idea how much is being approximately output at the engine...
I get around town on average 15.5l/100km and highway crusing at 100-110km is on average 14-14.5l/100km. these are the figures I get after the last of the exhaust was changed...
I can email the dyno scan if anyone is interested, it has the before and after outputs on it....

anyway my 2.5 cents worth (before tax and GST).. to at least support ersko's findings that his ecomnomy figures are comparable to mine.. but I certainly never had as bad as to what esrko had...

I am sure ersko only said what he said to do some fishing....I am an ex-owner of a well tuned 4.2 EFI Patrol and can say the words " NO WAY JOSE"....

When we quote fuel consumption we should burn 1000litres and then do the calculation, which takes away the dodgey fuel bowser counter, the hair trigger bowser which wasnt an issue when you filled up b4.,, etc etc.....

hi voxson, i can see where you are coming from but unfortunately my patrol only has a 150lt tank not 1000lts. i filled the tank, drove 840kms pulled into a servo and could only get 120.23 litres back into the tank. i wouldnt think that the servo owner would err in my favour therefore there is no way that i put more than 120.23 litres in! i havent stopped the clock at 1/4 tank, drove a bit, filled and then when it was at 1/4 again on the gauge, said ok thats 840 out of ???? litres. from a full tank where u cant get any more in, then drive ( even 200 k's) and fill back to where u can't get any more in again is about as accurate as u can get! on this thread there is now another guy who says he is getting the same and if u look back to my original question dated 14 jul post number 14656 there are a couple more guys there saying the same thing. i guess maybe it was a colder day the 2nd time i filled up and the tank had shrunk.....................
