I thought I would start this topic to show how many people around the world have been on a dyno with their Coopers/Ones.
This is a Cooper with software, K&N Typhoon and exhaust.
It shows three lines for HP and Torque.
The green one shows the stock HP.
The other two show the HP with all his mods and a more finely tuned software is what created the black line.
HP : 122 at flywheel
Stock : 111hp
Drivetrain loss : 17%
Dyno :Cartec
This is a Cooper with aFe intake and custom exhaust.
He produced 119,7hp at the flywheel and 101hp at the wheels.
Drivetrain loss = 18%.
Dyno : Superflow
This is a Mini One which had 88hp stock.
With Bluefin software, K&N Typhoon with custom heatshield and exhaust he now has 121,7hp at the flywheel and 103hp at the wheels.
His custom heatshield:
His dyno sheet:
Dyno : Superflow
Mini Cooper
Software
Supersprint headers
Supersprint midpipe
Supersprint exhaust
Pipercross Viper intake
HP : 128hp at the flywheel
Nm : 178
Drivetrain loss : 19%
This guy pulled 102 and 103hp at the wheels.
This puts him at about 116 - 117hp at the flywheel.
Dyno : Mustang dyno

He didn't include a dyno sheet, so these are his words:
so I took the mini to the dyno and my first pull was 102hp and 108 tq.
then I pulled a 103 with 99 tq
then 100 with 98 tq
sad day on the mustang haha...
I was kinda hoping for 125 range but I guess the cooper wasnt true to the stock 115. whatever formula the guy used on his calculator said I gained about 8 hp from the intake and exhaust.
Also, a Dutch group of Mini Cooper owners (8 cars) did a dyno day.
They collected all the data and put it in a pdf file.
Note how all the Cooper produce around 115hp at the flywheel stock.
The pdf file also includes all the modifications.
The highest was 121hp (flywheel) with software, intake, exhaust.
Drivetrain loss was around 22%.
This guy called "Beek Autoracing" is the number 1 tuner in Holland.
He builds racecars and works together with some of the best known European tuners.
Many people don't believe in MTH anymore because 99% of the people who bought MTH software, produced about 10hp less than was promised to them.
They sent several letters, e-mails and got no real answer from MTH.
Some of them got their money back, some didn't.
...testing of any kind, be it on a dyno, a flowbench, or even a road test, the results are only as good as the testing method, and more importantly, the ethics of the tester. False or inflated claims, however, have a way a coming around to bite the ones who foster them on their unsuspecting customers...
Again, not the number of mods that are required to get that amount of power.
This package does not come cheap.
A modded One is at the same level as a modded Cooper.
So a Cooper with the same mods, wil produce the same power as this One.
The reason why a One gains so much power, is because it's a detuned version of the Cooper.
Part of that detuning is the software that restricts the engine power.
So with a software upgrade a One can gain a lot of that restricted power back and on top of that the same amount of power that you gain with a Cooper.
You can almost predict where yours might be from the variation of samples here.
I tried to emulate the original JCW tuning kit which MINI stated was 126 HP on my '06.
So with
JCW Intake
JCW Head
JCW Exhaust
JCW Software
I'd be happy to be around ~125. If I win a free pull from the local MINI club it would be nice to hook it up.
Anyone know if the midlands vs getrag make a difference on drivetrain loss?
