We need more of this pure craftsman on the channel. Big D is a legend.
Where have you guys been? I've missed my Sunday morning videos 👍
Best looking GQ Patrol on CZcams, tasteful mods. Love the Lift and those wheels are lovely. It still looks original. Enjoy it but look after it and know when to stop modifying, don't go too far! Less is more sometimes, and you have such a clean vehicle to start with. Good job!
What a worthwhile dyno session! Eric not only seems to know his shit, he is a really good teacher as well.
Before and after driving comparison must be chalk and cheese! Look forward to seeing how she goes out on the tracks now...
could have done a run with the hat installed but no intake pipe to tell if its the pipe/filter or the hat (I think it might be the hat). However the torque gains down low is really the gains that mattered for offroad and around town driving.
Best thing I did was ditch the LPG. the weight saving alone were worth it plus was finding it annoying to find LPG when remote as it’s not common anymore. Plus todays prices of LPG it’s cheaper to run it on petrol. A GU 90L rear tank bolts straight in and even the hoses are correct for plumbing it.
It doesn't help that the taxi industry has entirely abandoned LPG, plus with Holden and Ford no longer much of a 'thing' in Australia now, and therefore they no longer manufacture cars here, there's no more LPG-only vehicles being made which were briefly a thing, there's very little incentive for servos to continue to offer LPG if next to nobody is buying it.
Cool vid. Nice change from the game changing 79 series on every other channel
would love to see a 75 or a non v8 79 on the channel tho
Yes
If that tuner goes to the airport...I wonder if he gets told, no "fire arms" allowed? :P
Hahaha very clever mate
It’s so good seeing these videos with Eric the bloke is a fountain of knowledge! Love how explains it all what’s going on what he’s doing etc etc!
Well done Dan!
My 2 bobs; the intake shroud over the gas regulator is the culprit - reason I reckon is there is more turbulence at that point (rather than the tube).
Regardless that is an excellent result - fuel economy should be substantially better too now.
Great listening to Eric, man knows his stuff 👍
a mate had an rb30 gq with a t04z on it, i tuned it and we took it to cape york, was a pretty cool car, twin locked on 33's
what a good bloke eric loves his job look how excited he gets most dyno tuners these days don't go into any details don't explain stuff all , just take your money eric makes your car reliable and teaches you all this information you need to know a credit to him well done and you did a awesome job an the old gq keep the vids coming have a soft spot for gq's even tho i drive a landcruiser haha
Always love the videos and appreciate the information and detail that is shared.
Very informative with down-to-earth comparisons and no bullshit. Well done.
Allways good to see a tuner in action
The low down performance improvement is massive, and that's will make the biggest difference.
I was really surprised by that, added 6kw with no filter.
When someone can easily explain what they are doing and why, you know they know what they are talking about
With the extra weight of the additional LPG tank, would you consider getting rid of the LPG setup and just running it on petrol?
Not sure about other states but in vic you have to have your car inspected an approved after you remove the gas system for insurance an rego purposes . Probably more hassle then it’s worth considering it seems like it’s a weekend car only
@Timothy Iorlano except it’s not because the price of gas an it’s efficiency means it’s more or less the same price as petrol at the moment
Register it in your missos name for 6 months then swap it back into your name as petrol... that's what I did in qld...
@@elliot7179 Last time I checked, a 30 cent difference between gas and 91 petrol at the moment, the same between 91 petrol and diesel. But you do get more power and range on petrol.
@@jonathanwishart9104 But you also use more gas for the same kms then if you were running petrol .
Great vid, the restriction is probably not the pipe (an LS runs the same size and makes 400hp) but more likely the shrouding, I read once the clearance after an opening should be equal to or grater then the opening radius as to not restrict flow.
Nice work Dan. You'll feel it on the road and at the bowser now. Enjoy 😉
What fuel economy is Dan getting on petrol vs gas?
That is such a tidy GQ. It's definitely a keeper.
Hey mate, seen a neat craft during work today. On a patrol instead of having the snorkel come out of the fender it came out of the bonnet close to the firewall.
My old 1988 lpg tb42 carby still had the STD air filter on top but between the carby and filter had a similar shaped ring to your inlet adaptor but only the size of the carby diameter roughly 50mm and this just flowed the gas from the LPG converter. My adaptor was only about 25-30mm in height.
Great result and for what you'r doing that is ample.
Low down torque is what you want for 4X4 work as that is pulling force.
Getting up hill without revving the guts out of the old girl.
thought about removing the LPG dan?
Blew my mind, even listening to goody talk, very knowledgable! 🤙
Imo bin the gas and fit a larger fuel tank mate 🤙
Erics is an Impressive Dyno operator I have worked with some of the best old-school Cosworth tuners. That long tube is an air intake heater the opposite function of a Turbo cooler. It will cost you big time up in Australia. Cooler air is a massive HP gain, Keep the intake pipes as short as possible in the engine bay. Or you might try insulating the tube, or diverting away from all of the heat sources, I'm not sure if that would work but it might be worth a try. A simple wire air temperature input sensor will show the results.
My thoughts are leading me to think a 4” snorkel, with custom air box with a slip on K&N filter. Kinda like 4” pipe to box, exposed box with kn filter and then four inch head to whatever diameter over the air intake shroud. Hope that makes sense, seems to be that would solve your air intake issues and heck you could probably make it out of pvc as a trial before committing to something custom and permanent 💁🏼♂️. Looking forward to it, and thanks for the video.
Geez look at that 1st gen Camaro - get that thing in a filmed piece! Beautiful.
What great bloke knows his shit and you motor held together well done
YES!! Dan’s back. 👌🏼
Absolutely love the GQ series, seeing it all recapped and presented at a decent technical depth is why I subbed to this channel in the first place
Goody's Garage, what a great name!
Love the TB content, thanks boys
My way of thinking, 10--11kw is 10--11kw that's a good number just by tuning it proper, I'd be happy with that. How much did the dyno tuning cost now days?
Top video, i threw my 300A in the bin, you'll never seal it and idle adjustment is not great. I switched to a 225 mixer which actually seals, has a more refined idle adjustment. I had to make a carby hat like the early hilux types and yep it was all done on exactly your model TB42s. .
Thanks for the cam information 👍
Awesome video mate been waiting for this keep it up boys
Thanks keil!
Wow. That was fascinating. Thank you.
Awesome rig and thanks for the content
Greetings from south africa 🇿🇦 😀
The old flame sleeves haha love it
Good result, you must be chuffed.
Great video too really enjoyed it.
"And that's what we're looking for!!" 🤣🤣
Seriously tho Dan's car is slick!!
i would wrap that cross over pipe try and keep your intake temps down in the bush
Nice to see how the tune went on this.
I was once a lpg/CNG fitter and tuner in NZ. Your Patrol looks like it's using a U.S Impco system. These are not the best for good air flow, they re very restrictive. If you want to get better air flow and so better fuel use, etc I'd look to change your whole system to a better system. Like I said Impco are very restrictive, but the up side is they are very simple. Once you fit a snorkel, as you've now already done, you should notice a difference as you are fitting a simple ram air system with the snorkel. A slightly bigger air box around your gas mixer will make a difference as will fitting an after market performance type air filter element. As you will know the way to make power and torque is to have the engine breath properly. More air in and more out makes a massive difference. You could go to headers and slightly bigger less restrictive exhaust. Might not make gains that you can feel, but should help with economy. Good video. Love watching you guys. I have to say that you are one of the better 4wd channels around. Keep it up
How good coffee and Aussie arvos vid, doesn't get much better
Cheers!
@@AussieArvos i dont know about everyone else, but I'd much rather watch this kind of dyno tune then someone who's Spent an arm and a leg on there car, it's just so much more relateable 🍻 keep up the good work guys
With the Cost of LPG these days i would just ditch the LPG system and gain the intake flow benefits
I tend to agree, but it does give him extra range.
@@BenMitro I removed my 90lt LPG tanks and just put in the standard 90lt Petrol take so I have a 90 and 75 ltr tanks now ... costs a few bucks to full but plenty of range :)
@@Eddastuff
Hey mate , got the same mod with 75 ltr tank waiting for install . What did you do to make the pumps work together .
Good ole tb42 love em
👍Really like the video's Dan! Thanks.
Great work guys
The filter setup on the 3, 4.2 litre is a well known restriction. Those chasing higher power levels replace the filter housing with a flat panel filter set up.
Those airbox lids are very restrictive, absolutely shitbox
Top job mate. It’s literally not HP figures it’s how it feels & drives. EG the idrive. People attack them for not adding Hp. But it’s how good it makes the vehicle feel.
Honestly found this really interesting boys!
Absolute master!
The restriction is the hole setup from the filter to the pipe to the shroud
Any car will make an improvement with the intake off,
Eric, you my mate are a mechanics mechanic. What a change from the suck and see jockeys who keep bolting shit on without understanding how engines actually work. Yes kids, this is what you call a tradesman
Has he noticed any difference in fuel economy? Thinking of doing the same thing to my tb45
You must have been happy with stand at the Melbourne four wheel drive expo. Thanks for talking the time to speak to me, I know it must have been hectic.
Yeah it was awesome Robert! we had a great time! No worries Robert! Thanks for saying hello !!
Good Results!
Is the air intake touching the engine? Because that wont take long before the intake pipe gets a hole
Legend
The 90deg bend in the top of the gu filter box is very restrictive. It looks 3” but actually is about 1.5” because the bottom of the tubing is flattened.
What torque did you make??? what clutch? Love the GQ
You should have run it on the dyno with just the carb hat and no pipe to check if it is the restriction
I see your still standin around with ya hands in ya pockets Dan. Nothing much has changed. Lol.
Should have disconnected the chrome pipe from the air box lid and ran it like that, would have given a good indication too where the restriction is
Please post a camping video! That'll be much interesting
Any plans to turbo it in the future
congrats nice video!😎🤙🛻📹
Another really good video.
You must be pretty happy with that nate.
Send it lad..
Im getting 78rwkw from my claped tb42 stocker no cam or head work currently building a new engine simalar comp ratio with a few more mods going for about 100 110rwkw na mines delco efi aswell
This man has stole restraint from the rest of us. I want it back!
If it was meant to be a racecar it wouldn't be shaped like a brick good job mate
Bigger cam more air. I reacon put a tad bigger carby on, and give it some juice. Ahaha. But in saying that. Will a 4inch pip n new airbox with 4inch snorkel help???!!! Questions to be answered
You Left me waiting too long :D
Pity you didn't do a run with just the hat on, without the 3" pipe. That would have been good info.
Don’t cut that virgin guard for a snorkel
My thoughts exactly
Would the snorkel make a difference with air intake?
Your back!!!!!!
Back! 👌
Nice Looking Patrol! I think Better not Push it too much! It is not racing car!
What kinda fuel economy you getting with that cam?
I went to the KISS concert on the Gold Coast last night, & now I'm thinking about your petrol/gas Patrol Dan. Keep It Simple Stoopid. Buy a diesel
Can I throw a question in here to get everyone thinking
With all the increae in touque. Especially on an older motor what extra strain is that likely to have on the crankshaft and pistons.
I have seen a couple of new ranger, hilux , Navra, that have been rechiped , remapped to pull vans that have a greater tare weight than the towing vehicle. Retuned for higher power , torque etc .
Pistons cracking , crankshaft breaking .etc
Was the increase in torque significant enough to create problems with the bottom end of the motor later down the track to me that is about a 10% gain in power and torque.
Interested on everyone's opinion
I don't think it would be an issue Andrew. A couple of mates GQ's have similar modifications and they haven't had any dramas. TB42's are pretty solid engines. Might be a different story if he went all out and turbocharged it and wound the boost right up.
I'd say that the Ranger/Hilux/Navara's that you're referring to are being taken way beyond what they were designed and engineered for.....significant power/torque increases and heavy towing will eventually find a short coming. Especially when you're talking small 4 cylinder common rail diesels that are highly strung.
Get rid of all of it and put a Holly sniper on it
no videos of you driving it?
are the petrol gu airboxes any bigger than the gu diesel airboxes
Just take the pipe off the housing then run it. Gawdd dam. Easy. Then you will know whats what
Man said tuning on lgp on bottom Text
Ah dual fuel and carb, the worst of both worlds.
Yep, go one or the other not both.
It's the percentage of difference and not the total number.
100~hp 🤔
Put an ls3 in it ! I've got one in a gu with 6sp auto . Magnificent!!! 204 kws at the wheels. 77 kws WTF im pretty sure i have a kitchen appliance with more grunt! Regards Tony.
More.
All cars make more power with no filter
It's been a while...
Oh dear. Wouldn't you try it with just the hat,then hat and pipe, then hat,pipe and filter.........
So what was the actual TORQUE figure before and after?
Went from 100nm to 125nm
Put a inline Fan between intake and intake Manifold. RAM THAT AIR DOWN THERE
