I am about to do a dyno test here in Paris, i dont know the brand , all i know it is for AWD cars . The tuner told me he will disconect the front diff. for the test ,cause he herd that some porsche awd front diff. were distroy after couple runs ?
Do you guys have any issues with this ?

Cheers

 

they also did that when they dynoed my 4S

but i have heard turbos getting dynoed without having to disconnect the front diff

 

AFAIK....the mustang is one of the only ones that will do a porsche without need for front diff. being removed (mechanical connection of front and rear tumblers). If in doubt disconnect it.
