Hey everyone just a note on the 6776 Ball bearing precision turbo , unfortunatly the turbo destroyed it self somehow but that isnt the point of this story ...a buddy loaned me a Turbonetics ball bearing 70 and after test running the car and trying to set the boost at the 30 psi i normaly ran with the 6776 bb the car was picking up knock ( Never any with 6776 ) and felt dogged ......the 6776 would get the car so bent out of shape on the street guys were scarred to ride with me ....the car would be all over to keep it in my lane was a chore ....car recently made 535 hp at the wheels and 710 ft lbs of torque on a Mustang dynometer ...........if you are contenplating these Turbos or the newer ones out now i think you will be highly impressed with them in comparison to older units youve run .......
