Hi all :)
I just got back from easter break and wanted to ask if I should be worried about my 98 mod 100 ser LC diesel with a safari turbo I am towing a van that weighs about 1350 kg dry I have built a new rear bar 20kg to carry my folding boat trailer which weighs about 80kg and I removed the two 4kg gas bottle holders and 1 bottle and replaced it with a 9kg bottle and ring I also made a bracket forward of the draw bar for my 6hp outboard and a bracket to hold the bike rack and a couple of bikes , on the roof of the cruiser I have a fuel tank, tinnie floor ,anchor and bucket and a 3.1 mtr tinnie I have draws in the back as well as a 40ltr fridge ,so the thing is that everyone that I talk to says that it should easily tow but I find myself dropping back to 3rd gear and doing 60-70 kph flat stick on hills it makes for uncomfortable driving and I would like to know if this is normal ??
If anyone can advise me on this I would really love to hear from you guys as I'm a bit worried , thanks guys for taking the time to read this I really appreciate it .

Regards J.B.

Over Easter I was up north and found that there was a very strong head wimd through the canefields which dragged me back. I could not get to 100kph sometimes but this all went away when we went inland and got away from the wind.

It does not sound usual but you may have driving into a headwind?

Hi JB, how ong since al the fuel filters were changed? We just had a similar problem before Easter up hiils. We dont have a turbo I know, but the main fuel filter was clogged to buggery on the GU, and also the small fine gauze filter on the injector pump. chenged both and she runs much better up hills now(for a non turbo anyway!)

Hi uncle
I did the filters a short while ago so I would hope it would not be that but if need be I will do them again but I have my doubts, One thing I have been thinking about is the Turbo and who I should see about whether its boost is set right I'm in western SYD if any one can recommend someone ??

Cheers John.

Denco at Wagga, They made my old man's 105 sing with the 3t caravan on the back. They can dyno it before and after.

How does the truck perform without the load?
Probably the first thing you should do is put the loaded rig onto a weighbridge. You might get a surprise at just how much weight you are dragging around. It all adds up pretty quickly.

p.s. forgot to add, check your tow ball weight while your on the bridge. That could also be a 'surprise' for you.

As for someone in west Sydney, I can recommend "West End Diesel" at Wetherill Pk.

I have found them to be helpful and reliable.

www.westenddiesel.com.au/

Check them out, even if they just go over it a get a little more out of it that's good.

If all else fails you may consider upgrading to a Nissan LOL.

Checking power output and weght makes sense . You have committed yourself to lots of drag , and thats a lifestyle decision and means lower speed .

Horsepower is proportional [ roughly ] to engine revs and in any one gear revs are proportional to speed . You love high gearing for economy so when you see low revs in overdrive , and if it still gives some overtaking performance , you think the vehicle designer has done the right thing . But remember that the vehicle designer was thinking light weight and higher speeds . If you approach a hill at low speed [ for a given gear ] horse power is barely able to maintain speed let alone start a climb . My rig is a petrol Disco pulling a camper weighing about 1200kg . I cruise at about 100ks and if I hit a big hill at that speed I wouldn't make it up in overdrive . But if I hit 110ks at the bottom of the hill [ no lectures please ] , I will breeze up it . If I towed a full sized caravan I would travel slower and I would go up hills one or two gears lower .

Austalians tend to have underpowered tow vehicles . If an American was thinking towing with a deisel he would start at 6.5ltrs . Talk to Bilbo .

So true. Aussies seem to worship feeble diesel motors. I think it's a hangup from the horrible old Pommie cars we grew up with.

The number of times I've heard someone tell me how well their big torquey diesel tows and yet I seem to see them struggling to get up even gentle hills unladen in 3rd gear.

They don't tow well and they aren't torquey. They do the job, but with virtually nothing in reserve. For the life of me I don't know why we love them. I was getting better fuel economy out of my 6.5 V8 than a 1HZJ and my mates 7.3 V8 gets better economy again, yet will hold 110kmh up and down any hill with ease.

We get sold pups.

As suggested weigh the rig, you might get a horrible shock especially comparing your weight to the manufacturers GVM and then add the weight of your trailer loaded. Don't forget the weight of driver and passengers as well.
Are your tyres taller/wider/more aggressive than standard, if so all will decrease the performance.
With a boat on top and trailer on the back the wind drag and weight are all against you.

When a Cruiser faults, the most obvious source of problem is an aftermarket add-on, which in this case is the Safari turbo.

However it is good advice to drag the van across a weighbridge next time you are packed up and going.

I wouldn't waste your time weighing the van. By the sounds of it it is a 15 FT or so at that weight, even with all the other gear you carry weight shouldn't be an issue. I guess you would know if you had a head wind.

I tow a 16 FT van (approx 1700 kg) with a Prado Td manual, even with extra weight on the roof and in the wagon I can still manage 90 - 100 KPH, so I would see why a 4.2 diesel would have problems.

I would get the Turbo setup checked and/or get an intercooler and better exhaust.

Thanx all I have taken all comments on-board and will try weighing everything 1st then I'm getting the Turbo checked out as I have been told that safari's are set at between 7-10 and allot of guys I have spoke to are running 12-14 so I'm keen to do some research on this alone so thanx again guys.
