138@4000(103kw)
torque 229lb ft@rpm (310 Nm) Thats according to the Jeep Patriot Brochure.

 

So the rolling road checked out you power on the front wheels , so you have screamed it up to higher revs than youve ever done .The coupling is trying to put power to your rears because it senses its needed.The crank bearings are getting hot & the Bores have just done equivilent of 4000 miles wear.Youve never seen so much smoke come out of your muffler...& your steering & suspension are also taking wear because you are riding on 22" wheels that the jeep was never designed .....Ok so " Worse case scenario" but go have an immediate oil change & hope that someone on the Used car lot doesnt ask too many questions!!

 

hmm mate, it was a 4 wheel drive rolling dyno, it was taken to it's peak power (@ 4000rpm). If a jeep cant handle a dyno run (same dyno is also used for diesel chip dyno tuning) then i might as well have bought myself a bicycle.

 

I don't think you can strap a bicycle to a dyno

 

Not sure what tiptronic is trying to say...

So what did the dyno say!? How many ponies is your diesel putting out?

 

How many ponies is your diesel putting out?

138.12 HP

 

engine: 103kw
at all 4 wheels: 88.5kw

 

can rolling roads measure torque ?

that's of more interest to us diesel people ?

 

quite possibly, however the dyno was displaying only power output (was a dyno shootout)

 

Nice! Wheels look awfully purrrtttyyy!!!!

 

Ok... you "almost" got me. I almost posted my question as to where the guy with his foot on the accelerator was... could't see him UNTIL I remembered you guy over on the other end of the pond drive on the wrong side...

sheeeeeeeeeezzzzzzzzzzzzzzzzzzz..............


Uncle Kah has had a rough day. I'm better now. Much better. Really... I am fine now. (twitch)

 

american or aussie horses?

 

American Mustangs...

 

I wouldnt know one horsepower from one donkeypower (is there such thing). converting it, i think Kahbrohn is right. Somewhere around 138-140 all wheel HP, almost one quarter of the power output of my weekend toy

 

Converter program here.

 

why would you dyno test your patriot it's not like it a mean machine from hell.

 

my other car is, its my local workshop i use, they had a dyno day and I dyno'd it.. Get over it

yeah im from eastern way, not even the suburbs ( 2 hours east of melbourne)

 

i'm guessing he's from broadmeadows!

they do things weird up there!

(meant in good humour broadz)

me from western suburbs

 

well lookin at the sign in the background hes in morwell so its more eastern than western

 

ahhh....the valley

 

Thanks for posting your experience, I found it interesting as it's not something I have come across before in relation to quantifying how much power is lost through the 4 wheel drive system on 4 wheel drive off road vehicles.

So correctly me if I'm wrong, the dyno calculated 108 kw (138 HP) at the flywheel/engine and measured 88 kw at the wheels (118 HP) so hopefully I have calculated correctly that equates to 15% loss through the transmission etc.

No idea if that is a typical figure, but obviously 4 wheel drive does sap more power than 2 wheel drive, but just goes to show 20 HP lost through all those bevel gears at maximum power. I bet the axles and transfer box must get quite warm, as 20 HP equates to 14 kw, so that's like having 7 x 2kw electric heaters on the go

I'll get my coat...
Cheers
