Flat spot

[vRS Carl]

As i said im not witch hunting.

I'd just like to know which is the correct method as then i know who's dyno results will be more accurate.

The correct method is the one used by Mike of DynoDynamics in the video posted on the previous page. The more power a car has, the more it will climb, the amount of climb doesnt affect the result, just as long as the car pulls away from the rear roller. Lower power cars wont climb quite as much as higher hp cars.

For those that are interested, here is the reply I recieved from DynoDynamics regarding strapping and climbing the roller:

Letting a car climb the front roller will make sure it makes traction on the gripped roller, strapping the car so it can't climb means it will not be allowed to make grip. A car will naturally want to climb and the bigger power cars have to be secured to prevent them climbing too much

If a couple of you want to come along and carry out some testing on the dyno then feel free, we will run the cars free of charge and show you the different strapping methods and explain why they are used.
