DYNO Tuning graphs

This page came about due to the incessant demand by all & sundry clamouring "I want to see some graphs" ;)
Dyno's measure rear wheel power & that is what I will be concentrating on, in kW.
Flywheel power & torque are normally calculated measurements. The factories usually measure the power on the FW, often using their own standards.

Nm =

kW x 9549
RPM

Some Dyno's calculate this better than others. MAHA being one of them.
I have found this rear wheel to crank HP guesstimator. Remember we take NO responsibility !
Here you can convert kW to Hp

Unless otherwise stated the before run shows a standard car, whilst the after car is after tuning the engine management for optimal efficiency. i.e. Fuelling, Timing, boost etc
If you want to find out what your vehicle might do with your specifically envisaged modifications, and can't find it above, then go to my page listing modification results.

I normally do not show Automatics due to the varying losses in the drive-train/lock-up and because they are difficult to hold in gear.

So, if you see a power graph that is totally different from what you expect, then please first read up on why this might differ from what your expectations.
If you bring me an older car or project, reading this article will prove beneficial The Ultimate Dyno Session Preparation Guide

This is what Dastek has to say about the Dyno report.

With each .jpg of the Dyno power measured at selected points on the rear wheels will be a short explanation on what we did and at the bottom of the graph a nomenclature explaining what each curve represents.
You can expect this page to be updated reasonably often. The last time a graph was published, was on 29 November 2024
If you have any suggestions on how to improve this service...
