Jack fuel economy after extrictor removal

Hi Boldjack,
Its a 3.5 manual which is supposed to be the moswt economical combination. Its also only got mild ats on it at monent with 45lb front and 35lb in the back tyres.
Yes a noticable improvement in power above 2000rpm, slight loss of torque below 1500rpm only noticable in first gear high range.
On a light throttle their is no noise increase but when you floor it their is an increase in noise(not unpleasent) The Jack I brought was the quickest of the ones I test drove. Its now quicker than the bosses v8 100 . I find I catch sedans on long steep pulls , and that is good for a 2 ton 4wd
Cheers Pete

Hi Pete
We have a 3.5 auto with 265/75 all terrains and like you say they are quite quick.
I like all your comments, except I am slightly concerned about the loss of torque at low rpm. Do you think it's enough to effect low speed steep hill (low range) stuff? You know, when you're trying to use the throttle nice and steady over uneven rocks.
Cheers BoldJack

Hi bold jack,
The fuel fig was obtained using 96oct. THe loss of low down torque is only evident in high first towing a trailer up a quite steep hill.
Do not forget your speedo and odo will be reading up to 10% slow because of the large tyres. As soon as we put larger tyres on the paj the economy dropped. I get better economy towing a 4.2 metre boat than the paj does with a canadian canoe on the roof(15l100). Pumping the tyres up helpes and I added an oil based additive to the drive line for extra protection and this could slighty cut friction. Also I try and coast up to lights and use cruise to maintain a constant speed .
I found before the throttle was too touchy, . First time I have had to much power..lol
Member Brad is a weath of info on this
Cheers Pete

Hi Pete
I calculated a 7.3 % difference in speed with 265/75s,that is when your speedo indicates 100 km/h your really doing 107.3 km/h. Also when you're doing your fuel calcs your odometer is showing less distance than what you actually travelled. In our case we must remember add 7.3% ,that is for every 100km indicated on the odometer we actually travelled 107.3 km. I think some people may forget to allow for this and blame the tyres for more than they actually impact fuel consumption.
It looks like there are more pros than cons .

Thanks BoldJack

LOL , at lest you new what I ment, footie thanks mate
. Long time since I went to school
Cheers Pete

Mate dirt roads and aggressive tyres will knock your fuel economy arround, and stick to a speed where the vehicle is doing it easy. Mine has got a bbar and driving lights on it . Also read my reply above on fuel
Cheers Pete

Hi Barry,
The manuals seem to be much better than the autos. Its seems to be better than my old 22r fourrunner towing my boat, its doesnot know its their were as the runner use to struggle a bit.
Biggest problem to getting good economy is me, darn hard vehicle to drive sedately. But about 90 seems a good speed if you can bear it. You will notice a bit more noise pulling hard in 4th gear towing .
The 3.5 compares favourably to the 4lt hilux at work. It gets coarse above 3500 rpm where as the Jack is silky smooth for a v6
Going to get a Uni filter shortly and try that
Cheers Pete
