Here is the video of our dyno day when the car spat it's toys out the pram
Luckily no damage has been done and on the good side we've found out why it's doing this so hopefully will be resolved today :?

They seemed very long power runs pablo - do they always wind it up for so long?

Glade to hear no damage mate, looks like she got a tad warm.

Yes mate they do as the car has no ecu he uses a device similar to a stephascope to listen to the engine for any signs of pinking as he winds it up. Some of the earlier runs were also to check how the car was fuelling once she came on boost.
The problem wasn't over-heating, it is sucking in air into the water system from a small leak point on the water pump causing over pressuriseing of the water system. :?

Run times vary from dyno to dyno I'm guessing that one is a Maha? Dynodynamix have much car friendly run times and is probably much more accurate

Ross, your right it is a Maha rolling road, unfortunatley for us there aren't that many rolling roads that cater for 4wd in the west midlands.
