The graph is showing the wheels horse power.

But the figure it made at the flywheel was 123bhp.

Ive scanned both of the graphs to help clear things up a bit:



The TOP graph shows the WHEEL torque & horsepower.

The one BELOW shows the CLUTCH (Flywheel) power.

I dont thinks its technically "De-EcoTec"ing it, but its just a general way of saying those bits are removed lol!

Thats what i was thinking Sean. It should redline at 6600, but the graph says different!

Its revs to 6600 on the rev counter, and it was ran to the redline on the rollers. Strange!

Cant see what would make the curve drop at the end, except the rollors beigh out slightly. The power doesnt feel to drop off whatsoever whilst driving...

Rev counter isn't 100% accurate. Like the speedo, it does over-read.

The curve drop is normal for the inlet layout and map on the X16.

Pmsl, of course it did if you believe every rolling road printout
So you've made about 40hp from a skimmed head?


Back to the thread, results sound about right, torques a bit lower than normal, but the torque graph is quite flat which is good

I'm a bit confused so a standard 1.6 makes 106 at the fly or wheels?

Because if you've only made 17bhp from all those mods then
