Jackaroo Recall and Performance

Yes they are 118 Kw rating.......on a flywheel dyno with no accessories attached.

They went through all their Jackaroo files for the Dyno and none got anywhere near mine with the new exhaust.

Im very pleased with the result and now its onto a Chip modification.

Cheers

Hi Steve..........yes that was the first recall, this is one that came up in June this year with Isuzu finally doing a worldwide recall of the 4JX1 and covers from 1998 to end of production.

This Is a different problem.........Holden told me that its the sleeves that are the problem for this one not the seals.......although the seals suffer degradatio because of it.

Oh just thought Id add a comment to my last. I did the same sort of Mod to my Isuzu MU (Exhaust) and got the same sort of results. And as for warranty its out of original warranty now anyway so it doesnt really matter.

By the way the guys at United told me that even the latest model Nissan, also rated at 118 KW, hasnt gone above 90 on their dyno and yes it accounts for driveline losses etc. So it appears that alternators, Power steering, Fans, Airconditioning all take a fair wack off the rated HP.

Even my tyres suck up about 5kw greater than the standard tyres. But that why Dynos are good. You can test the good with the bad.

Id hate to be paying for the new injectors Steve!!!!!!!!!! Glad its free!!!!!

Gday Jack(Maybe)

Yes it was a good outcome. Ive just been looking over the Dyno test and its actually 120 kw at the back wheels. And it does suffer losses due to the Auto and Big Tyres.

I got the exhaust system through 4wdsystems in South Oz as well as a 133 Litre fuel tank.

The Exhaust was about 900 bucks, 2 3/4 inch mandrel bend system. But im happy as hell with it as Im about to travel to Melbourne to pick up my new offroad Van and the extra power will not go astray having that on the back.

Im also looking at a chip upgrade which if their claims are true.......should give me about 150 kw at the back wheels. Isuzu diesels have always responded well to improvements.

Its not just the exhaust pipe is the muffler too............a free flow muffler makes a world of difference and comes included in the supplied system. Not telling you to suck eggs here Jack, but a mandrel bend system doesnt bend the system out of round on its diameter. It allows for much better flow than a conventional system which creates Eddies etc in the system.

The Guys also did Exhaust temperature tests along the length of the new system and they came up really well.

ANy more questions??

Cheers

Gday Jeff from Geoff,

Yes im also under the same impression about the Rodeo. It went straight from the old 2.8 to the 3.0 and missed the 3.1 Jackaroo engine. It also has a front mounted intercooler rather then the Top Mount, which should actually be better but doesnt look as Sexy!!!

Im led to believe that a chip is available for the Rodeo motor. Also a decent exhaust wouldnt go astray at all!!! So there are some options for you. Ive always liked a good exhaust as it allows much better flow of exhaust gasses and allows the turbo to spin up quicker due to less back pressure. This also increases economy and power in Theory.

I put a 2 1/2 inch system on my Isuzu MU (3.1TD) and its now a pocket rocket for a Diesel. My wife drives it in the City and we still get about 750 Kms out of a tank.
Ill have to put an intercooler on next!!!!!!!! It rated 88 KW at the back wheels when it was supposed to put out 88 KW at the fly wheel.

Dont know about the economy stakes yet with the Jack but Id say Ill get better economy out of her yet!!

Another option is to go for the Gas Conversion for Diesel...........this is interesting as it doesnt replace the Diesel (like a petrol engine) it coexists with it. I was told to expect about 30 percent increase in Power with the Jack and much better economy to boot. So there is another option.

But everything is relative and it costs money. The cheapest thing for you to do is get a Unifilter (better flow than a standard) and even that will make a small difference.

Hope this helps a bit.

Cheers
Geoff

Jeff, Just make sure you find someone that knows what they are doing. They can be a Fiddly motor and having access to a Dyno would also help.
